Description
Technical field
The utility model belongs to truck mixer, especially relates to a kind of water route protective device of truck mixer.
Background technology
The water supply cleaning device of existing concrete agitating lorry normally adopts vapour-pressure type to supply water, in air inlet pipeline, only add pressure-reducing valve and ball valve, guarantee the pressure of water tank by the pressure-reducing valve set pressure, though the shortcoming of this water supply installation is the pressure of supply water that has guaranteed water tank, but can not guarantee the pressure of source of the gas and chassis air feed gas bag, be easy to cause gas bag hypotony or routed gas, in case air pressure is low excessively, tend to cause car brakeing malfunctioning, bring certain potential safety hazard to traffic safety.
Summary of the invention
The purpose of this utility model provides a kind of truck mixer pressure water supply water route protective device, can guarantee the pressure of supply water of water tank, can guarantee the pressure of air feed source of the gas again, and the traffic safety of vehicle is played a protective role.
The purpose of this utility model is achieved like this: a kind of truck mixer pressure water supply water route protective device, comprise ball valve and pressure-reducing valve, it is characterized in that: support is welded on the side of the front stall of truck mixer water tank downside, on this support, rectangular box is installed, on the and arranged on left and right sides wall of casing, offers installing hole respectively with the right part of front side wall with bolt; The left transit joint of hollow is installed with nut on the installing hole on the casing left side wall, the right section of this left side transit joint stretches in the inner chamber of casing, be connected with the inlet end of ball valve, its left side section then is connected with gas bag by pipeline II, and gas bag then is connected with source of the gas (air compressor machine) by pipeline III; The outlet side of ball valve is connected with the inlet end of single tube road gas shield valve with the transit joint of hollow, the outlet side of single tube road gas shield valve is connected with the inlet end of pressure-reducing valve with the transit joint of hollow again, this pressure-reducing valve is installed on the bearing on box bottom of being welded in the casing, in addition, in the dead ahead of pressure-reducing valve one Pressure gauge is installed, this Pressure gauge and pressure-reducing valve link together by screw pair, and allow this Pressure gauge be inlaid in the installing hole on the casing front side wall, can be seen by the user, the right side port of pressure-reducing valve connects with right transit joint, in the installing hole on the right side of casing, the inner chamber in the outlet side of right transit joint (right-hand member) with pipeline I and water tank is connected this right side transit joint with nut check; Required air pressure is braked more than 6bar in the chassis of truck mixer, be lower than 6bar and can influence braking ability, the pressure of water tank requires to guarantee at 2bar, before the work, with the pressure setting of single tube road gas shield valve at 6bar, the pressure-reducing valve pressure setting is at 2bar, during work, source of the gas work, gas process pipeline III is to gas bag, ball valve is opened, and gas arrives water tank from gas bag through pipeline II, ball valve, single tube road gas shield valve, Pressure gauge, pressure-reducing valve and pipeline I; If gas bag pressure is lower than 6bar; can not reach the opening pressure of single tube road gas shield valve; gas does not arrive water tank; if gas bag pressure is higher than 6bar; reach the opening pressure of single tube road gas shield valve; gas shield valve in single tube road is opened; gas arrives pressure-reducing valve; arrive water tank through pipeline I again; if tank pressure reaches the set pressure 2bar of pressure-reducing valve, then pressure-reducing valve cuts out, and so on the one hand tank pressure is remained under the pressure of regulation; the pressure of gas bag also remains at the pressure 6bar that gas shield valve in single tube road is set on the other hand, has so just guaranteed the brake safe of driving.
The truck mixer pressure water supply water route protective device that the utility model proposed, rational in infrastructure, safe and reliable, can guarantee the pressure of supply water of water tank, can guarantee the pressure of air feed source of the gas again, the traffic safety of vehicle is played a protective role.
Now in conjunction with the accompanying drawings and embodiments the truck mixer pressure water supply water route protective device that the utility model proposed is further described.
Description of drawings
Fig. 1 is that the master of the truck mixer pressure water supply water route protective device that proposes of the utility model looks schematic diagram.
Fig. 2 is the local schematic top plan view of the truck mixer pressure water supply water route protective device that proposes of the utility model.
Among Fig. 1, Fig. 2: 1, source of the gas 2, gas bag 3, ball valve 4, single tube road gas shield valve 5, Pressure gauge 6, pressure-reducing valve 7, water tank 8, casing 9, pipeline I 10, front stall 11, bearing 12, pipeline II 13, pipeline III 14, support
Specific implementation method
From Fig. 1, Fig. 2 as can be seen: a kind of truck mixer pressure water supply water route protective device, comprise ball valve 3 and pressure-reducing valve 6, it is characterized in that: support 14 is welded on the side of the front stall 10 of truck mixer water tank 7 downsides, on this support 14, cuboid casing 8 is installed, on the and arranged on left and right sides wall of casing 8, is offered installing hole respectively with the right part of front side wall with bolt; The left transit joint of hollow is installed with nut on the installing hole on casing 8 left side walls, the right section of this left side transit joint stretches in the inner chamber of casing 8, be connected with the inlet end of ball valve 3, its left side section then is connected with gas bag 2 by pipeline II 12, and 2 of gas bags are connected with source of the gas (air compressor machine) 1 by pipeline III 13; The outlet side of ball valve 3 is connected with the inlet end of single tube road gas shield valve 4 with the transit joint of hollow, the outlet side of single tube road gas shield valve 4 is connected with the inlet end of pressure-reducing valve 6 with the transit joint of hollow again, this pressure-reducing valve 6 is installed on the bearing 11 on box bottom of being welded in the casing 8, in addition, a Pressure gauge 5 that communicates with it is installed in dead ahead at pressure-reducing valve 6, this Pressure gauge 5 and pressure-reducing valve 6 link together by screw pair, and allow this Pressure gauge 5 be inlaid in the installing hole of right part on casing 8 front side walls, can be seen by the user, the right side port of pressure-reducing valve 6 connects with right transit joint, this right side transit joint, is connected with the inner chamber of water tank 7 with pipeline I 9 in the outlet side of right transit joint (right-hand member) in the installing hole on the right side of casing 8 with nut check; Required air pressure is braked more than 6bar in the chassis of concrete mixing and transporting car, be lower than 6bar and can influence braking ability, the pressure of water tank 7 requires to guarantee at 2bar, before the work, with the pressure setting of single tube road gas shield valve 4 at 6bar, pressure-reducing valve 6 pressure settings are at 2bar, during work, source of the gas 1 work, gas arrives gas bag 2 through pipeline III 13, ball valve 3 is opened, and gas arrives water tank 7 from gas bag 2 through pipeline II 12, ball valve 3, single tube road gas shield valve 4, Pressure gauge 5, pressure-reducing valve 6 and pipeline I 9; If gas bag 2 pressure are lower than 6bar; can not reach the opening pressure of single tube road gas shield valve 4; gas does not arrive water tank 7; if gas bag 2 pressure are higher than 6bar; reach the opening pressure of single tube road gas shield valve 4; single tube road gas shield valve 4 is opened; gas just arrives pressure-reducing valve 6; arrive water tank 7 through pipeline I 9 again; when water tank 7 pressure reach the set pressure 2bar of pressure-reducing valve 6, then pressure-reducing valve 6 cuts out, and so on the one hand water tank 7 pressure is remained under the pressure of regulation; the pressure of gas bag 2 also remains at the pressure 6bar that single tube road gas shield valve 4 is set on the other hand, has so just guaranteed the brake safe of driving.
