Description
Technical field
Pump valve field of mechanical technique is the utility model is related to, is specially a kind of fuel charger shut-off valve.
Background technology
Shut-off valve belongs to forced seal formula valve, so when valve is closed, it is necessary to apply pressure to flap, it is close to force
Front cover does not leak, and when medium is by entering valve below flap, the resistance that overcomes required for operating force, is rubbing for valve rod and filler
Power and the thrust as caused by the pressure of medium are wiped, the power of closing valve is bigger than the power of valve opening door, so the diameter of valve rod is big, it is no
The failure of valve rod bending can then occur, be divided into three kinds by connection mode：Flanged joint, screwed connection, be welded to connect, from self sealss
Valve occur after, the medium of shut-off valve flow direction just changes by entering valve chamber above flap, at this moment under pressure medium effect, pass valve
The power of door is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly, meanwhile, under medium effect, this form
Valve is also tighter.
1. existing fuel charger is driving flap to move down with shut-off valve using engineering transfer silk valve rod, so that by valve
Close, but flap can be rotated with silk valve rod is turned, such flap just has valve inner wall and produces friction, so will result in valve
Valve is worn, and causes valve to end imprecision.
2. existing fuel charger shut-off valve easily occurs in use, the sealing performance between flap and connector is relatively low
Leakage situation, it is not very convenient to open, and when flap is worn because of the erosion of fluid media (medium), may result in flap without
Method is blocked communication port, causes the generation of leakage, this just needs the flap that worker frequently more renews, and causes work efficiency to drop
It is low, reduce the service life of shut-off valve.
Utility model content
It is proposed in the above background technology to solve the purpose of this utility model is to provide a kind of fuel charger shut-off valve
Problem.
To achieve the above object, the utility model provides following technical solution：A kind of fuel charger shut-off valve, including valve deck
It is described and valve body, the valve deck bottom are installed with valve body by locking nut, are plugged with inside the valve deck and turn silk valve rod
Turn to be fixedly connected with handle at the top of silk valve rod outer wall, be rotatably connected to mandril nut at the top of the valve deck, the valve body side is opened
Equipped with oil inlet passage, the valve body opposite side offers oil discharge passage, and connector, the connection are offered at the valve body axle center
Recessed mouth is offered on the outside of mouthful, the recessed mouth inner homogeneous is bonded with sealing ring, flap, institute are connected with inside the connector
State side of the flap away from connector and be installed with fixed frame, cooperation is installed with the top of the fixed frame and turns silk valve rod
Threaded hole, the side at the top of the fixed frame are fixedly connected with sliding block, and the side of the valve interior wall is installed with cooperation and slides
The slide bar of block.
Preferably, the crevice place of the valve deck and valve body is uniformly bonded with gasket.
Preferably, the crevice place of the mandril nut and handle is socketed with mandril gasket.
Preferably, the described turn of one end of silk valve rod away from handle is fixedly connected with limited block.
Preferably, the recessed mouth coordinates with flap.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model drives flap to move by fixed frame, ensure that flap will not be sent out during moving up and down
Row rotates, and improves the service life of flap, and when in use, by rotational handle, handle band turn silk valve rod rotates, fixed frame
As the rotation for turning silk valve rod is moved down along slide bar direction, so as to drive flap to move down, which prevent flap to exist
It can rotate in mobile process, rub so as to avoid flap and valve interior wall, improve the service life of flap.
2nd, the utility model is coordinated by flap and recessed mouth, and sealing ring will make the leakproofness of shut-off valve more with valve flap contacts
It is good, while also prevent flap and produce friction with recessed mouth, after fixed frame drives flap to be moved down into connector position, flap
It can be connected in recessed mouth, the sealing ring in recessed mouth separates flap and recessed mouth, ensure that the better tightness of shut-off valve,
Also prevent flap and recessed mouth at the same time has friction.
