Existing plunger valve is generally all applied in liquid line, often with solid particle polluter in liquid medium, these solid particle polluters are along with can to causing wearing and tearing when liquid medium enters into plunger valve, affect the sealing between plunger and valve seat, thus have impact on the working life of plunger valve.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of reasonable in design, can filter the solid particle polluter in liquid medium, and the plunger valve that the solid particle after filtering can conveniently be discharged.
For achieving the above object, the technical solution of the utility model includes valve body, valve gap, valve rod, plunger, plunger guide cover, seal ring and valve rod lifting drive handwheel, valve body is provided with inlet pipeline, outlet conduit, body cavity and valve seat, body cavity is divided into upper chamber and lower chambers by valve seat, the lower end of valve rod is fixed in described plunger interlock, and this plunger longitudinally guiding slippage is arranged in plunger guide cover, and be provided with the seal ring be sealed and matched with outer plunger surface slippage between this valve gap and plunger guide cover, also include filtering mechanism, described filtering mechanism includes hemisphere filter screen, described inlet pipeline outer end fixing seal docking is connected with externally connected pipe, the periphery of described hemisphere filter screen is fixedly installed shirt rim portion, the shirt rim portion of this hemisphere filter screen is fixedly clamped between the exterior edge face and the interior edge face of externally connected pipe of inlet pipeline, hingedly relative to the outer end of hemisphere filter screen on described externally connected pipe inwall be provided with guide plate, this guide plate includes interconnective straight flange plate and arc plate, the outer end of straight flange plate is rounded end, the outer end of arc plate is free end, yielding support spring is provided with between described guide plate and externally connected pipe inwall, described externally connected pipe inwall is provided with solid impurity relative to the lower end of straight flange plate and stores chamber, the inner Residue extraction pipeline storing chamber with solid impurity and be communicated with is provided with in the tube wall of this externally connected pipe, the outer end of this Residue extraction pipeline is connected with flexible rubber pipe, flexible rubber pipe is provided with sealing pipe clamp.
By this setting, liquid medium enters into the inlet pipeline process of valve body from externally connected pipe, in liquid medium, solid particle can by hemisphere strainer filtering, thus prevent solid particle polluter from entering into valve inner, in addition, owing to being provided with guide plate in externally connected pipe, flowing medium understands arc diverted flow to hemisphere filter screen by guide plate, long-pending overlay on solid particle on hemisphere filter screen and can be washed away downwards by the liquid medium of this direction movement after filtration, solid particle is swept solid impurity to store in chamber and assemble temporarily, thus can prevent solid particle from continuing blocking hemisphere filter screen, and after solid impurity stores the full solid particle polluter of chamber storage, by opening sealing pipe clamp, solid housing impurity is stored chamber from solid impurity and draws cleaning, solid impurity can be realized and store reusing of chamber, the utility model said structure designs, reasonable in design, can not only filtering solid particles impurity, the more important thing is the solid housing impurity blocking filter screen that also can not make to filter, ensure the normal use of filter screen.
Further setting is fixedly connected with cooperation by stud with nut between described valve gap and valve body.By this setting, valve gap and valve body are connected stable, easy accessibility.
Further setting is that the upper end of described plunger is provided with valve rod retaining collar, and the lower end of described valve rod is plugged in this valve rod retaining collar, and by divided ring and plunger and cap form both interlock be fixedly connected.By this setting, make between plunger and valve rod, to form stable fixing linkage structure.
In sum, the utility model has the advantages that vibrational power flow is reasonable, can filter solid particle in liquid medium, the more important thing is the solid particle polluter blocking filter screen that also can not make to filter simultaneously, ensured the normal use of filter screen.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
