Abstract
The utility model provides a kind of Novel groove safety check, described safety check comprises: valve body and non-return sheet, described non-return sheet is obliquely installed, its one end is slidably connected with the rotatingshaft being fixed on described valve interior wall, can do radial motion around described rotatingshaft, its other end is connected with the restraining groove that is arranged on valve interior wall bottom; The two ends of described valve body are respectively arranged with the first groove and the second groove, and described the first groove is used for being connected with pipeline with the second groove; On described rotatingshaft, be provided with sensor, described sensor is connected with controller, and described rotatingshaft is also connected with electric motor drive, and described motor is connected with controller.By restraining groove is set, effectively prevent the upset of non-return sheet; Even if it overturns in the past, also can make its automatic turning change of team original position by the structure such as sensor, controller, ensure the normal use of groove safety check, improve working efficiency, be convenient to industrially promotion and application.
Description
Technical field
The utility model belongs to valve processing technique field, relates in particular to a kind of Novel groove 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.
In prior art, the application of groove safety check is very extensive, in the process of use groove safety check, because non-return sheet is that soft material is made, in there is extraordinary situation, there will be larger backflow, thereby make the upset of non-return sheet in the past, make safety check lose due function.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel groove safety check, to solve in prior art, in the process of use groove safety check, because non-return sheet is that soft material is made, in there is extraordinary situation, there will be larger backflow, thereby make the upset of non-return sheet in the past, make safety check lose the defect of due function.
In order to realize the purpose of this utility model, the utility model provides a kind of Novel groove safety check, described safety check comprises: valve body and non-return sheet, described non-return sheet is obliquely installed, its one end is slidably connected with the rotatingshaft being fixed on described valve interior wall, can do radial motion around described rotatingshaft, its other end is connected with the restraining groove that is arranged on valve interior wall bottom; The two ends of described valve body are respectively arranged with the first groove and the second groove, and described the first groove is used for being connected with pipeline with the second groove; On described rotatingshaft, be provided with sensor, described sensor is connected with controller, described rotatingshaft is also connected with electric motor drive, described motor is connected with controller, in the time that described rotatingshaft rotation amplitude is greater than predefined value, described sensor transmits a signal to described controller, and motor rotates described in described controller control, and described motor drives described rotatingshaft to be turned back to predeterminated position.
Wherein, described controller is PLC controller.
Wherein, described rotatingshaft is connected with described electric motor drive, specifically refers to, described rotatingshaft is fixed with the first gear, and described motor output shaft is fixed with the second gear, and described the first gear is connected with the second gear transmission.
The beneficial effects of the utility model are compared with prior art, by restraining groove is set, effectively to prevent the upset of non-return sheet; Even if it overturns in the past, also can make its automatic turning change of team original position by the structure such as sensor, controller, ensure the normal use of groove safety check, improve working efficiency, be convenient to industrially promotion and application.
