Abstract

The invention provides a method for manufacturing a bouncing type stop valve to solve the problems. The stop valve can be more easily opened and closed through a bouncing device arranged in a stop valve body, the required time is shorter, and the method is more suitable for material flow systems which need to be rapidly opened and closed. The method for manufacturing the bouncing type stop valve is characterized in that the stop valve body, a pressing handle, a valve rod, a valve cavity, the bouncing device, a spring, a needle valve clack, a material passageway and a passageway groove are adopted, the pressing handle is arranged above the stop valve body, the valve rod is arranged below the pressing handle, the valve cavity is formed below the valve body, the bouncing device is arranged on the upper portion of the valve cavity, the spring is arranged on the lower portion of the valve cavity, and the needle valve clack is arranged below the spring. The method has the advantages that by means of the bouncing device in the valve body, the opening operation time and the closing operation time of the stop valve are shortened, and the effect can be more remarkable for the material flow passageway which needs to be rapidly opened and closed.

Description

technical field [0001] The invention relates to the field of stop valves, in particular to a manufacturing method of a pop-up stop valve. Background technique [0002] The globe valve is a control component in the fluid delivery system, which has the functions of shutting off, regulating, diverting, preventing backflow, stabilizing, shunting or overflowing and releasing pressure. Globe valves used in fluid control systems, from the simplest globe valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. The application range is relatively wide, but its working method is basically through the rotation of the handwheel to achieve the purpose of pressurization or decompression. This increases the operating time. Contents of the invention [0003] The problem to be solved by the present invention is to provide a manufacturing method of a bouncing stop valve, which opens and closes the stop valve through...
