Description
Technical field
This utility model belongs to stop valve equipment technical field, is specifically related to a kind of sylphon seal stop valve.
Background technology
Valve is control parts in pipeline fluid induction system, and it is used to change path section and media flow direction, have water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are various.Valve can be used for controlling water, steaming
The all kinds such as vapour, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid fluidly flow, the operating pressure of valve can supertension from 0.0013MPa to 1000MPa, operating temperature is from the high temperature of the ultralow temperature of-269 DEG C to 1430 DEG C.
The control of valve can use the multiple kind of drive, as manually, electrically, surge, pneumatic, worm gear, electromagnetic driven, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear driving etc.；Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, valve relies on driving or automechanism makes it lift, sliding, swing or gyration, thus the size changing its flow area controls function to realize it.But existing valve mechanism is complex, and manufacturing cost is higher, opening and closing more inconvenience, service life is shorter.
Utility model content
The purpose of this utility model is to provide a kind of sylphon seal stop valve, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of sylphon seal stop valve, including valve body, described valve body be arranged over clamp nut, the both sides, lower section of described clamp nut are provided with hands wheel, the lower section of described handwheel is provided with control valve, the bosom of described valve body is provided with valve rod, the lower end of described valve rod is provided with corrugated tube, the lower section of described valve rod is provided with flap, the lower section of described flap is provided with passage, the upper cover of described valve body is connected by stud is fixing with the bottom of valve body, the lower left of described valve body is provided with left intake-outlet, the lower right of described valve body is provided with right intake-outlet, it is provided with fixing bar between described left intake-outlet and right intake-outlet and valve body.
Preferably, described stud is provided with Intermediate gasket with the junction of valve body.
Preferably, the outer end of described left intake-outlet and right intake-outlet is both provided with adpting flange.
Preferably, the inner side of described control valve is provided with sealing surface, built-up welding Co base cemented carbide layer on sealing surface.
Compared with prior art, the beneficial effects of the utility model are: this sylphon seal stop valve, and double-layer seal design (corrugated tube+filler) can avoid leakage；Do not have fluid to damage, reduce energy loss, improve safety of factory equipment；By making at sealing surface weld deposit Co base cemented carbide, valve body is more wear-resisting, friction resistant performance is more preferable, service life is longer；By the design of corrugated tube, it is possible to protection valve rod is from erosion medium resistance；This sylphon seal stop valve, have rational in infrastructure, seal reliable, function admirable, the advantage such as handsome in appearance, can significantly extend the service life of stop valve simultaneously, can use with popularity.
