Abstract
The utility model relates to a valve which is installed on an air compressor. The valve is characterized in that a valve plug made up of the metal is movably arranged on an inlet passage of a valve body, an exhaust plug is movably arranged on an exhaust opening on the valve body which is on the right lower part of the valve plug, and a magnet is arranged on the exhaust plug. The utility model integrates a checking valve and an exhaust valve. The utility model has double functions of the non-return function and the exhaust function. The structure of the air compressor system is greatly simplified. Meanwhile, the performance is reliable, and the use is convenient.
Description
The utility model relates to a kind of valve that is contained on the air compressor.
Air compressor we productive life and work in be found everywhere, be to depress in nothing to carry out in order to make air compressor, thereby avoid the motor excess load that reduce starting current, air compressor generally also is equipped with outlet valve when safety check is housed when starting once more.Existing outlet valve is a kind of to be manually operated valve, when starting air compressor, all need use the handling valve at every turn, and residual air is discharged, shed pressure, use pretty troublesomely, convenient inadequately, a kind of is solenoid valve, though exempted the each manual trouble of manually operated valve, price is expensive, reliability is also poor.
The purpose of this utility model is exactly a kind of non-return unloading valve that provides at above-mentioned situation, and it integrates safety check and outlet valve, and is simple in structure, easy to use, reliable performance.
Solution of the present utility model is: the valve plug that is made of metal is equipped with in activity on the gas-entered passageway of valve body, and venting plug is equipped with in activity on the relief opening of the valve body under the valve plug, and the venting plug upper end is contained in magnet, and its detailed content is described below referring to accompanying drawing:
Referring to accompanying drawing, non-return unloading valve of the present utility model, it is characterized in that the valve plug (6) that is made of metal is equipped with in activity on the gas-entered passageway of valve body (5), in the process that valve plug (6) moves up and down, promptly enter valve body when starting air compressor pressurized air, its pressure promotes valve plug (6) and moves upward, gas-entered passageway is opened, and pressurized air enters gas holder through this valve, closes air compressor, valve plug (6) moves downward under action of gravity, closes gas-entered passageway.Relief opening (13) on the valve body (5) under the valve plug (6) is gone up activity venting plug (11) is housed, magnet (10) is equipped with in venting plug (11) upper end, when valve plug (6) when being in closed condition, under magnetic force, the venting plug (11) that magnet (10) are housed is attracted on the valve plug (6) that is made of metal, relief opening (13) is opened, residual gas in the valve body (5) is discharged from relief opening (13), make motor depress starting once more in nothing, starting has energy-saving effect rapidly.When starting air compressor once more, pressurized air enters valve body (5), overcomes magnetic force, promote valve plug (6) and move upward, open gas-entered passageway, meanwhile, venting plug (11) moves downward losing under the situation of magnetic force, and relief opening (13) is closed.Valve plug of the present utility model (6) is cross, the upper end puts in the elongate recesses of the bonnet (3) that is connected with valve body (5), the lower end puts in and is contained in the valve plug cover (8) that has certain altitude on the valve body (5), in the process that valve plug (6) moves up and down, play the guiding role, simultaneously, valve plug cover (8) with certain altitude can be closed and all the time can exhaust valve plug (6) venting plug (11) in the process of opening very soon, seal ring (7) and valve body (5) sealing are equipped with in the centre, guarantee that the sealing after gas-entered passageway is closed is reliable.The lower end of venting plug of the present utility model (11) is taper, cooperate with the cone shape hole on the relief opening (13) of valve body (5), sealing is strong, the centre has its top of a step to pass to be contained in the hole of the vent plug cylinder (12) that has aperture (18) on the valve body (5), motion to venting plug (11) play the guiding role, when venting plug (11) moves upward, open exhaust port (13), residual gas in the valve body (5) enters in the vent plug cylinder (12) from aperture (18), discharge from relief opening (13) again, thereby reach the purpose of release, step plays position-limiting action.
The non-return unloading valve that the utility model provides, integrate safety check and outlet valve, have the function of safety check and outlet valve concurrently, overall structure is greatly simplified, utilize the characteristic of magnet to come the designing and arranging air valve, make its structure become very simple, reliable performance, the valve plug Analysis of Nested Design becomes certain altitude, guarantees that air compressor starts the final vacuum plug and can close soon, and it is the unlikely exhaust that is in operation, and easy to use.
Accompanying drawing is represented specific embodiments of the present utility model.
Accompanying drawing is represented structural drawing of the present utility model.
According to embodiment shown in the drawings, valve plug cover (8) with certain altitude is housed at the middle part of valve body (5), cross valve plug (6) lower end that is made of metal puts in the valve plug cover (8), seal ring (7) is equipped with at the middle part, bonnet (3) is equipped with by bolt (11) and spring washer (2) in the top of valve body (5), the top of valve plug (6) puts in the concave elongated of valve gap (3), between valve body (5) and the valve gap (3) sealing gasket (4) is housed, have relief opening (13) in the bottom of valve body (5), top is taper, vent plug cylinder (12) is housed, its side has aperture (18), vent plug cylinder (12) is passed on the top of venting plug (11), and be connected with magnet (10) by sunk screw (9), the bottom of venting plug (11) is taper, there is a step at the middle part, between vent plug cylinder (12) and the valve body (5) sealing gasket (14) is housed, valve body (5) bottom is by bolt (15), spring washer (17) is equipped with bottom flange (16).
Claims (3)
1, a kind of non-return unloading valve, feature of the present utility model is the movable valve plug (6) that is made of metal that is equipped with on the gas-entered passageway of valve body (5), relief opening (13) on valve body (5) under the valve plug (6) is gone up activity venting plug (11) is housed, and magnet (10) is equipped with in venting plug (11) upper end.
2, non-return unloading valve according to claim 1, it is characterized in that valve plug (6) is for cross, the upper end puts in the elongate recesses of the bonnet (3) that is connected with valve body (5), the lower end puts in and is contained in the valve plug cover (8) that has certain altitude on the valve body (5), and seal ring (7) and valve body (5) sealing are equipped with in the centre.
