Description
Technical field
The utility model belongs to valve processing technique field, relates in particular to a kind of novel elevating safety check.
Background technique
Valve is the controlling component in fluid delivery system, have cut-off, adjusting, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various, produce and use standard without unified, production firm often goes to manufacture according to user's actual demand.
Current, lift check valve is widely applied, and in application process, its non-return piece is owing to contacting with described valve body for a long time, and grown service time, easily produces wearing and tearing, causes sealing effect bad, affects user's use.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel groove safety check, and to solve in prior art, its non-return piece is owing to contacting with described valve body for a long time, and grown service time, easily produces wearing and tearing, causes sealing effect bad, affects the defect of user's use.
In order to realize the purpose of this utility model, the utility model provides a kind of novel elevating safety check, described safety check comprises upper cover, valve body and non-return piece, spring, described upper cover is fixedly connected with by described fixing bolt with described valve body, described upper cover lower end is provided with fixing column, described fixing column is provided with fixed hole, described non-return piece comprises directional post and blocks piece, described fixed hole and described directional post are slidably connected, described fixed hole is connected by spring with described shutter, under normal state, described spring is in compressive state; Described valve body both sides are provided with the first flange and the second flange, and described valve body comprises import and outlet, and the position of described import is lower than the position of described outlet; The described piece lower end surface of blocking is provided with annular flange, described valve body with described in block piece connection and be provided with the groove matching with described flanged structure.
Wherein, described fixing column upper end outer wall is provided with screw thread, and described upper cover is provided with screw thread fixed hole, and described fixing column is threaded with described screw thread fixed hole.
The beneficial effects of the utility model are, compared with prior art, on non-return piece, collar flange is set, on valve body, relevant position arranges groove, makes in closed, flange and contact grooves seal, sealing effect is better, and is not easy wearing and tearing, in addition, the utility model is provided with fixing column adjustable structure, can regulate required pipeline pressure according to the extent of elasticity of spring.
