Problems solved by technology

[0003] In the process of valve production and processing, it is often necessary to check the valve. Generally, it is necessary to check the connection of the valve port and the air tightness of the valve. The pipe enters the valve port to carry out the connection detection of the valve port, and then circulates the air flow between the two connecting cylinders to detect the air tightness of the valve through the change of air pressure in the sealing chamber. However, in the actual detection process, often due to the clamping and fixing of the valve Tilting affects the actual detection effect, making the actual valve detection not accurate enough

Abstract

The invention, which belongs to the technical field of valves, in particular relates to a detection device for valve machining, thereby solving a problem that in the prior art, valve detection is notaccurate enough. The device comprises a sealed chamber provided with a base, a fixed frame and a top seat which are fixedly connected in sequence; a sealing door is arranged at one end of the fixed frame; air cylinders are fixed to one side of the top of the base and one side of the bottom of the top seat correspondingly, a fixing rack is fixed to one end of each of the air cylinders, a horizontally-arranged electric clamping jaw is fixed to one side of the fixing rack, detection pipes are arranged in the middle of the top of the base and the middle of the bottom of the top seat correspondingly, and the detection pipes are connected with rotary telescopic mechanisms. According to the detection device, the two electric clamping jaws are abutted against the end opening of the valve upwards and downwards through the air cylinders, then the electric clamping jaws are used for clamping and fixing the valve, so that the valve is kept vertically placed after being clamped and fixed, the detection accuracy of the rotary telescopic detection pipe is guaranteed, and the actual valve detection accuracy of the device is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a detection device for valve processing. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications. The valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. . [0003] In the process of valve production and processing, it is often necessary to check the valve. Generally, it is necessary to check the connection of the valve port and the air tightness of the valve. The pipe enters t...
