Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, a pneumatic control valve according to the present invention includes a valve body 1 and a pneumatic switch, that is, the valve body 1 and the pneumatic switch constitute the main components of the present invention.

[0013] The first flow channel opening 31 , the second flow channel opening 37 and the valve port 32 are formed on the valve body 1 , and the first flow channel opening 31 communicates with the second flow channel opening 37 through the valve port 32 . Described runner mouth one 31 and runner mouth two 37 can be import and export mutually, and when promptly runner mouth one 31 is import, runner mouth two 37 is outlet, and when runner mouth one 31 is outlet, runner mouth two 37 is import; It can effectively increase the convenience of installation and use of the present invention.

[0014] The valve port 32 is provided w...

Abstract

The invention relates to the technical field of switching valve devices, in particular to a pneumatic control valve. The pneumatic control valve comprises a valve body. A first runner opening, a second runner opening and a valve port are formed on the valve body. The first runner opening is communicated with the second runner opening through the valve port. A pneumatic switch is arranged at the valve port. Rapid switching is achieved through the pneumatic switch. In addition, the first runner opening and the second runner opening can be inlets and outlets with each other, and connection is convenient. The pneumatic control valve has the advantages of being simple in structure, small in size, low in starting pressure and the like.

Description

technical field [0001] The invention relates to the technical field of switch valve devices, in particular to an air pressure control valve. Background technique [0002] Pneumatic valves are valves driven by compressed air. They are easy to use and safe. They can be controlled on site or remotely. They can control a single valve or centralize multiple valves. Control, if combined with an electronic computer, program control can be realized. Pneumatic valves are widely used in various fields such as chemical industry, papermaking, food, medicine, drainage, gas, etc., especially in the field of automatic control of waterways. Existing pneumatic valves include pneumatic ball valves, pneumatic butterfly valves, etc., which mainly rely on the rotation of pneumatic actuators to control the valves and are widely used, but they have the following defects and deficiencies, such as large size, complex structure, slow switching, difficult manufacturing and processing, starting pressu...
