Abstract
The utility model relates to a leakproof valve which is suitable for the existing running water valve. The leakproof valve which is suitable for the existing running water valve is mainly composed of a valve rod, a valve cover, hollow hemispherical rubber sealing rings, a valve seat, and a valve core, wherein, the seal between the valve cover and the valve seat is realized through the hollow hemispherical rubber sealing rings. The hollow hemispherical rubber sealing rings are fixed on the inner circles of the valve cover and the valve seat, and is fixedly sealed and connected with the connecting rod of the valve core. When the leakproof valve which is suitable for the existing running water valve is opened, the valve core is made to upwards move by water pressure, and water flows out. When the leakproof valve which is suitable for the existing running water valve is closed, the valve rod is pressed on the water inlet cavity of the valve seat, and the leakproof valve which is suitable for the existing running water valve are closed. The leakproof valve which is suitable for the existing running water valve has the advantages that the leakproof valve which is suitable for the existing running water valve is watertight, and is convenient to be maintained.
Description
The utility model relates to a kind of valve that prevents that water leakage phenomenon from taking place.It is applicable to various common existing valves, in case leak.
That CN90203167.8 discloses is a kind of the water nozzle of phenomenon " can avoid metal run out ", and its spool and valve seat are through improving, and the valve port of closing current is positioned at water-inlet cavity, and when the do time spent of valve rod because of stripped thread switch out of hand, water nozzle can be closed voluntarily.The phenomenon thereby unlikely generation is metalled run out.
In addition, existing valve all adopts asbestos washer to push down the snout cavity leakproof, along with service time along long, the time and water leakage phenomenon arranged.Need throttle down just can repair during maintenance.
Task of the present utility model is a kind of leakproof valve of design, to reach switch freely, purpose water-tight and easy to maintenance.
This leakproof valve adopts following design proposal to realize.
A kind of leakproof valve, it mainly is made up of valve rod, valve gap, rubber seal, valve seat and spool.Its structure characteristic is valve rod and valve gap screw-thread fit, has the hole in the lower end of valve rod, and with the connecting rod Spielpassung of spool.Fixedly rubber seal is arranged on the connecting rod in addition, and valve core is positioned on the water-inlet cavity, valve gap and valve seat scyewed joint.
Described rubber seal is the hollow hemisphere shape.
Accompanying drawing is this leakproof valve overall structure sectional view, and each title is among its figure:
1, valve rod 2, valve gap 3, rubber seal 4, valve seat 5, spool.
Accompanying drawing has provided a specific embodiment of this leakproof valve.
Valve rod 1 is a copper casting, and connects with valve gap 2 thread seals, and valve gap 2 is an ironcasting.Rubber seal 3 is fixed by pad and nut and is sealed on the connecting rod of spool 5, the outer of rubber seal 3 is by garden crush seals in the interior garden of valve gap 2 and the valve seat 4, and promptly sealing between valve gap 2 and the valve seat 4 is that rubber seal 3 by the hollow hemisphere shape realizes.When opening valve, under the pressure effect of tap water, make on the spool 5 and move, and drive rubber seal 3 and move simultaneously, water is flowed out; When cut-off valve left, valve rod 1 was pressed on the water-inlet cavity of spool 5, and (referring to accompanying drawing) makes it to cut off the water supply.
The advantage of this valve is: water-tight, easy to maintenance.
Claims (1)
1, a kind of leakproof valve, it mainly is made up of valve rod, valve gap, rubber seal, valve seat and spool, valve rod and valve gap scyewed joint, valve gap and valve seat scyewed joint, it is characterized in that: between valve gap and the valve seat by the rubber seal crush seal of hollow hemisphere shape, spool is positioned on the water-inlet cavity of valve seat, and the connecting rod of valve core connects with the rubber seal fixing seal, and the connecting rod of spool cooperates with the interporal lacuna of valve rod upper end.
