Abstract

The invention discloses a high-pressure balance valve for a proportioning cabinet. The high-pressure balance valve comprises air inlet pipes, valve main bodies, glands and valve covers, wherein each air inlet pipe is arranged on the corresponding valve main body; a valve main body sealing ring is arranged in a groove of the corresponding valve main body; each valve main body is inserted into a hole of the corresponding valve cover and is fastened by a corresponding valve main body nut; each valve cover is pressed on the corresponding gland to form an air chamber; a valve seat is arranged in each valve main body; a valve spring and a valve core are arranged in each valve seat; a valve inner core is arranged in each valve core. The high-pressure balance valve provided by the invention has good use effect on pressure balance of high-pressure gas and high proportioning accuracy and pressure resistance up to 4MPa.

Description

technical field [0001] The invention relates to a gas proportioning cabinet, in particular to a high-pressure balance valve of the proportioning cabinet. Background technique [0002] The pressure resistance of the balance valve of the existing proportioning cabinet is generally below 1.0 MPa, which leads to a limited scope of application, causing too much inconvenience, and needs to be improved. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a high-pressure balance valve of a proportioning cabinet with reasonable design, convenient use, simple operation and high pressure resistance. [0004] The present invention is achieved through the following technical solutions: [0005] A high-pressure balance valve for a proportioning cabinet, which is special in that it includes an air intake pipe, a valve body, a gland, and a valve cover; the air intake pipe is installed on the valve body, and a valve body sea...
