Abstract
The utility model relates to a power saving mass flow switch valve without leakage, which is composed of a valve body, a valve cap, a partition board, a piston, a piston rod, and a valve core. The valve body has mass flow through holes, and the through holes are connected with the inner pore canal and the through hole on the valve cap respectively. The valve cover is provided with four small screwed valves used for controlling the communication and the blockage of the inner pore canal, the through hole and the piston cylinder. The utility model has the advantages of compact structure, labour saving, no leakage, and easy operation. The utility model is suitable for larger valves, and can be used for the liquid delivery or the air delivery.
Description
The utility model technical field valve kind, the particularly a kind of nothing laborsaving logistics switch valve that leaks outside.
At present, the normally used valve of people is to lean on to open and close valve with screw thread rotation, the rotation friction of valve core sealed cover surface, and the outside seal filler also is that rotation rubs, and sealing is easy to destroyed, and phenomenon easily leaks outside.Have some nothings valve that leaks outside to lean spool in the hope of automatic compensate for wear amount, but spring works and be easy to corrosion in liquid (or gas), also easily produce elastic force and weaken, cause structure malfunctioning, the generation leakage phenomenon by spring force.
The purpose of this utility model provides a kind of nothing that opens or closes by logistics pressure control spool laborsaving logistics switch valve that leaks outside.
Task of the present utility model is finished with the following methods: it is made of valve body, valve gap, dividing plate, piston, piston rod and spool.Have the logistics through hole to be communicated with inlet hole on the housing of valve body and have through hole to be communicated with exit orifice, and all with the valve body exterior.Valve gap leans on the inlet hole side of valve body to have inner duct jljl opening to communicate in correspondence, and valve gap has through hole in the exit orifice side of corresponding valve body, and its two ends are interlinked to the outside with through hole and valve gap respectively.The valve gap both sides are upper and lower respectively to have a through hole to pass valve gap, and minor thread valve and locknut respectively are housed.The dividing plate spinning is on valve body, and there is piston the piston rod upper end and passes the dividing plate lower end is equipped with spool, and fastening with locking nut.The valve gap top is integrally closed or unlimited sealing with plug, and valve gap connects with being threaded into structure or connecting with flange plate structure with valve body.The area of piston is bigger than spool area.
The utility model compact structure, the opening and closing valve is laborsaving, does not produce to leak outside, and handles easily, is applicable to bigger valve, all can use this valve to carrying liquid or gas.
Fig. 1 the utility model sectional view,
Below in conjunction with accompanying drawing the utility model is described in further detail:
This switch valve is made of valve body (1), valve gap (5), piston (9), piston rod (18), spool (13), dividing plate (17) and minor thread valve (3), locknut (4).This valve adopts one to control greater than the piston (9) of spool (13) area and 4 minor thread valves (3), locknut (4) and logistics pressure and to finish.This kind valve can use under two kinds of operating conditions: the one, and the logistics environmentally safe discharges micro-material, for example pressurized air when opening and closing; The 2nd, logistics has pollution to environment, but the logistics import and export have the certain pressure difference to come the opening and closing valve.
Have logistics through hole (2) and through hole (11) to be communicated with valve body (1) inlet hole and exit orifice respectively on valve body (1) housing, and same valve body (1) is interlinked to the outside.Valve gap (5) both sides are upper and lower respectively to have a through hole to pass valve gap (5), and a minor thread valve (3) and locknut (4) all are housed thereon.Dividing plate (17) spinning is on valve body (1).Piston rod (18) upper end is equipped with piston (19) and is passed dividing plate (17) lower end spool (13) is housed, and is fastening with locking nut (15).Valve gap (5) has inner via hole (16) to be communicated with the hole of upper and lower two the dress minor thread valves of this side (3) by valve body (1) inlet hole side, and can communicate by jljl opening (2).Valve gap (5) has through hole (8) to be communicated with the hole of upper and lower two the dress minor thread valves of this side (3) by valve body (1) exit orifice side, and an end communicates with through hole (11), and the another port leads to outside the valve gap (5).Better for guaranteeing sealing, piston (9), dividing plate (17) sliding position all are equipped with seal ring (10).The same valve body of dividing plate (17) (1) contact position is equipped with seal ring (12).Spool (13) is equipped with seal ring (14) with valve body (1) surface of contact place.Through hole (8) is tapped through hole (7) at valve gap (5) top outlet section, mainly is that this valve screws in plug when being used in contaminated material and carrying and seals this channel outlet.The top of valve gap (5) screws in sealing with plug (6).
Working procedure is as follows: drive valve 1.: logistics enters logistics through hole (2) from valve body (1) inlet, open the minor thread valve (3) on valve gap (5) top of valve gap (5) bottom of entrance point and outlet end, the minor thread valve (3) of closing entrance point top and outlet section bottom.Band presses logistics to enter the bottom of piston (9) through the through hole of logistics through hole (2) and valve gap (5) bottom minor thread valve (3), utilizes logistics pressure that piston is moved upward, and spool (13) also moves upward, and valve is opened.2, close valve: close the minor thread valve (3) on valve gap (5) top of valve gap (5) bottom of entrance point and outlet end, open entrance point top minor thread valve (3) and outlet end bottom minor thread valve (3).Logistics enters piston (9) top from the through hole of valve gap (5) the top minor thread valve (3) of entrance point, by material pressure piston (9) is moved downward, and spool (13) also moves downward, and valve is closed.
When switch valve, residual air is discharged by tapped through hole (7) or through hole (11) then by through hole (8) in the former piston.Tapped through hole (7) is used for nonpollution environment to be used, and through hole this moment (11) is stifled to be closed; Tapped through hole (11) is used to have under the befouling environment situation and uses, and tapped through hole this moment (7) stops up.
Minor thread valve (3) all can only not controlled inner duct (16) and through hole (8) and the interior logical or pass of piston cylinder because of opening or closing of minor thread valve (3) influences the unimpeded of inner duct (16) and through hole (8).There is locknut (4) minor thread valve (3) outside, is with pretightening force after minor thread valve (3) open and close, and logistics can not leaked from screw thread.
