Description
Technical field
The utility model relates to a kind of stop valve, especially a kind of novel cutoff valve.
Background technique
Pipe valve valve, it is one of most popular a kind of valve, why very popular it is, be due in opening and closing process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, be not only applicable to mesolow, and be applicable to high pressure, stop valve mechanical part does not directly contact with medium, be not suitable for using at higher temperature and pressure, therefore be not suitable for using in steam medium, how to design a stop valve, change present stop valve design unreasonable go out, therefore, a kind of novel cutoff valve is devised for the problems referred to above.
Model utility content
The purpose of this utility model is to provide a kind of novel cutoff valve, to solve the problem proposed in above-mentioned background technology.
The purpose of this utility model is achieved by following technical proposals: a kind of novel cutoff valve, comprise valve body, black box, pneumatic head cavity of resorption, mounting hole, exhaust port, pneumatic head epicoele, cluster spring, gas source interface, water-leaking hole, threaded coupling, seal ring, valve rod and sealed base, described valve body is connected with threaded coupling by valve rod, described valve rod lower end arranges sealed base, inside described threaded coupling, seal ring is set, described threaded coupling upper end and be positioned at valve rod exterior edge face black box is set, described black box upper end arranges pneumatic head cavity of resorption, described pneumatic head cavity of resorption lower end arranges water-leaking hole, upper end sidewall arranges gas source interface, described pneumatic head cavity of resorption upper end arranges pneumatic head epicoele, described pneumatic head epicoele upper end arranges mounting hole, inner side arranges cluster spring, exterior edge face arranges exhaust port.
Further, described black box is arranged on valve rod exterior edge face, is positioned within pneumatic head cavity of resorption.
Further, described valve rod upper end and cluster spring are interconnected.
Further, described gas source interface is positioned at pneumatic head cavity of resorption and pneumatic head epicoele joint.
Further, the sealing between described pneumatic head cavity of resorption and valve body is made up of the seal ring of multiple layers of different materials.
Compared with prior art, the beneficial effects of the utility model are these novel a kind of novel cutoff valves, reasonable in design, mechanical part and medium have direct contact to be adapted at higher temperature and pressure use, therefore be comparatively suitable for using in steam medium, working life is of a specified duration, is applicable to promoting the use of.
