Description
Technical field
The utility model is related to slide-valve design technical field, more particularly to a kind of guiding valve for vacuum excrement collector system.
Background technology
Guiding valve uses relatively broad as a kind of valve for controlling fluid flow in current every field, and guiding valve mainly includes
Arrangement valve block in slide valve and cylinder, slide valve, cylinder drives the valve block in slide valve to make translational motion under the influence of air pressure
Realize the control of fluid flow, when guiding valve is applied in vacuum excrement collector system, slide valve both sides by through hole respectively and
Transferring box, the blow-off pipe of closet are connected, and guiding valve is controlled logical between transferring box and closet by controlling the movement of internal valve block
Disconnected, during blowdown, guiding valve is closed, and malleation is become by negative pressure in transferring box, and the dirt of transferring box is discharged into casing, valve block and transferring box
The one side being connected is malleation, and the one side that valve block is connected with closet is that atmospheric pressure, i.e. valve block two sides produce pressure difference, in pressure
May cause valve block slight deformation and make seal failure under difference effect so that pressure rise in piston chamber body and cause slide valve
Split and damage, the service life of guiding valve is shorter.
Utility model content
The purpose of this utility model be overcome prior art exist defect, there is provided a kind of service life it is more long for true
The guiding valve of empty set closet system.
The utility model solves the technical scheme that its technical problem used：A kind of cunning for vacuum excrement collector system
Valve, including slide valve and cylinder, arrangement valve block in slide valve, the both sides of slide valve offer hole position it is relative to and transfer
The connected first through hole of case, closet and the second through hole, open up third through-hole, between the both sides plate face and slide valve of valve block on valve block
The first sealing ring and the second sealing ring are respectively arranged, cylinder realizes closing and the opening of guiding valve with moving valve plate movement, on slide valve
Arrangement pressure relief opening.
Beneficial effect：When valve block makes seal failure because of pressure difference slight deformation, after air pressure enters in the chamber of slide valve, gas
Press and the external world is discharged to by the pressure relief opening set on slide valve, the pressure in the chamber of active balance slide valve prevents guiding valve
Body ruptures because air pressure is raised, and effectively improves the service life of guiding valve.
Brief description of the drawings
Fig. 1 is structural representation when the utility model guiding valve is closed.
In figure：10- slide valves, 11- first through hole, the through holes of 12- second；20- cylinders；30- valve blocks, 31- third through-holes；
The sealing rings of 41- first；The sealing rings of 42- second；50- check valves.
Specific embodiment
With reference to Fig. 1, the utility model will be further described.
Arrangement valve block in a kind of guiding valve for vacuum excrement collector system, including slide valve 10 and cylinder 20, slide valve 10
30, the both sides of slide valve 10 offer hole position it is relative to the through hole of first through hole 11 and second that is connected with transferring box, closet
12, third through-hole 31 is opened up on valve block 30, it is respectively arranged the first sealing ring 41 between the both sides plate face and slide valve 10 of valve block 30
With the second sealing ring 42, cylinder 20 moved with moving valve plate 30 and realizes closing and the opening of guiding valve, and pressure relief opening is arranged on slide valve 10
13。
When the utility model is used, when guiding valve is closed, the first sealing ring 41, the second sealing ring 42 correspond to the respectively
Sealing effectiveness is realized in one through hole 11, the position of the second through hole 12, restarts cylinder 20 and valve block 30 is moved into third through-hole 31 and
One through hole 11, the relative opening for realizing guiding valve in the position of the second through hole 12.During blowdown, guiding valve is closed, and is become by negative pressure in transferring box
Malleation, the one side that valve block 30 is connected with transferring box is malleation, and the one side that valve block 30 is connected with closet is atmospheric pressure, i.e. valve
The pressure of the two sides of piece 30 is unequal, the slight deformation of valve block 30 may be caused under differential pressure action and makes seal failure, and sealing is lost
After effect, air pressure enters in the chamber of slide valve 10, afterwards, the air pressure row of pressure relief opening 13 directly by being set on slide valve 10
Go out, the pressure in the chamber of active balance slide valve 10, prevent slide valve 10 from being ruptured because pressure is excessive, effectively improve guiding valve
Service life.
Further, the connection of the pressure relief opening 13 check valve 50, after the failure of the interior sealing of slide valve 10, air pressure enters slide valve
Cavity indoor pressure is raised in 10 chamber, after the pressure in the chamber of slide valve 10 reaches certain limit value, check valve
50 are opened, and air pressure is discharged by the pressure relief opening 13 set on slide valve 10, the pressure in the chamber of active balance slide valve 10,
Meanwhile, check valve 50 can prevent ambient atmos, dust etc. from entering in the chamber of slide valve 10.
Preferably, the pressure relief opening 13 and check valve 50 are at least each sets one.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With new.The obvious change or variation extended out by spirit of the present utility model are still in protection of the present utility model
Among scope.
