Technical Field

The utility model relates to a valve field, more specifically say, it relates to a filterable trip valve in area.

Background

The demand of valve products, especially high-performance valve products, for valve households in petrochemical industry, electric power department, metallurgical department, chemical industry, urban construction and the like in China is increasing day by day. In infrastructure, pipeline transportation is often adopted for fluid transportation, and the valve is a control component therein, has functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure, and the like, and plays an indispensable role. Shut-off valves, also called shut-off valves, are commonly used in fluid line systems to control the opening and closing of the medium and to throttle the flow. The normal cut-off valve is composed of valve body, valve cover, valve rod, valve clack and hand wheel, and its closing principle is that the valve clack is riveted on the valve rod, and the opening and closing of the valve port is controlled or the opening of the valve port is regulated with the lifting of the valve rod to achieve the aim of throttling.

The existing gas valve has more defects in the use process, for example, most of existing shut-off valves are inconvenient to filter impurities in the fluid, and the fluid in the shut-off valves is easy to seep out from valve rods to influence the use of the valves.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a take filterable trip valve of area.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a filterable trip valve, includes the valve body, it has the runner to run through in the valve body, the runner both ends are valve port, characterized by: be equipped with the valve gap on the valve body, it has sealed lid to peg graft on the valve gap, sealed internal thread connection of lid has the dwang, the dwang runs through sealed lid and valve gap in proper order and extends in the valve body, the inside seal assembly who encircles the dwang that is equipped with of sealed lid, seal assembly includes fixed block, first sealing washer and inflatable seal circle, be formed with the first annular that is used for placing first sealing washer between fixed block and the sealed lid to and place inflatable seal circle's second annular, set up intercommunication second annular and external through-hole on the sealed lid, be equipped with the valve of connecting inflatable seal circle in the through-hole, the one end that the dwang extended into the valve body is equipped with sealed valve clack, the inside opening part of valve body is equipped with the filter screen.

Through adopting above-mentioned technical scheme, first sealing washer is hugged closely and sealed dwang, and the sealed through-hole simultaneously of dwang is strengthened once more after inflatable seal aerifys, places the fluid and flows out from the through-hole, prevents simultaneously that the filth from getting into the valve from the through-hole, sets up the filter screen, can be at the in-process that this gate valve used, be convenient for carry out filtration treatment to the impurity in the fluid to guaranteed fluidic cleanness, inflatable seal receives the extrusion of fixed block after aerifing and can carry out better sealing to the valve body.

The utility model discloses further set up to: the cover is equipped with the return spare of connecting the valve gap on the dwang, the return spare includes the elastic component and sets up the spring in the elastic component.

Through adopting above-mentioned technical scheme, the dwang can return under the effect of return piece, and is more laborsaving, and the collision that takes place between the sealed valve clack and the valve gap when elastic component and spring fit can prevent the dwang from rising simultaneously.

The utility model discloses further set up to: and a sealing block is arranged on the sealing valve clack.

By adopting the technical scheme, the fluid is better prevented from flowing away through throttling.

The utility model discloses further set up to: the dwang is located external one end and is equipped with the stopper, works as when sealed lid is hugged closely to the stopper, the dwang is fixed.

Through adopting above-mentioned technical scheme, make the more stable fixed of rotation through the stopper when dwang rising state.

The utility model discloses further set up to: the sealing cover is provided with a fixing groove and a fixing thread block which is rotatably arranged on the fixing groove and tightly abuts against the sealing cover.

Through adopting above-mentioned technical scheme, will seal the lid and be fixed in the valve gap.
