Description
Technical field
The present invention relates to pump valve field of mechanical technique, 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.
The content of the invention
It is an object of the invention to provide a kind of fuel charger shut-off valve, to solve proposed in the above background technology ask
Topic.
To achieve the above object, the present invention provides following technical solution：A kind of fuel charger shut-off valve, including valve deck 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, described turn of silk
Handle is fixedly connected with the top of valve rod outer wall, is rotatably connected to mandril nut at the top of the valve deck, the valve body side offers
Oil inlet passage, the valve body opposite side offer oil discharge passage, offer connector at the valve body axle center, outside the connector
Side offers recessed mouth, and the recessed mouth inner homogeneous is bonded with sealing ring, flap, the valve are connected with inside the connector
Side of the valve away from connector is installed with fixed frame, and the screw thread for coordinating and turning silk valve rod is installed with the top of the fixed frame
Hole, the side at the top of the fixed frame are fixedly connected with sliding block, and the side of the valve interior wall, which is installed with, coordinates sliding block
Slide bar.
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 invention are as follows：
1st, the present invention drives flap to move by fixed frame, ensure that flap will not be issued during moving up and down and turns
It is dynamic, improve the service life of flap, when in use, by rotational handle, handle band turn silk valve rod rotates, fixed frame with
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 in movement
During can rotate, rub so as to avoid flap and valve interior wall, improve the service life of flap.
2nd, the present invention is coordinated by flap and recessed mouth, and sealing ring will make the better tightness of shut-off valve with valve flap contacts,
It also prevent flap at the same time and produce friction with recessed mouth, after fixed frame drives flap to be moved down into connector position, flap meeting
It is connected in recessed mouth, the sealing ring in recessed mouth separates flap and recessed mouth, ensure that the better tightness of shut-off valve, together
When also prevent flap and recessed mouth and have friction.
