Abstract

The invention provides a valve seat. According to the valve seat, a first hole segment and a second hole segment are formed in the valve seat, and a magnet is mounted in the first hole segment; a limiting ring table and a fixing portion are arranged on the inner walls, located at the two sides of the magnet, in the first hole segment respectively; and when the magnet gets loose, the limiting ringtable and the fixing portion can block the magnet so as to prevent the magnet from falling off. A diaphragm one-way valve is further provided. The diaphragm one-way valve comprises a pipe, wherein thevalve seat, a diaphragm, a support and a filter screen are arranged in the pipe, the filter screen is fixedly arranged on the support, and the diaphragm is movably arranged between the support and the valve seat. A production process of the diaphragm one-way valve is furthermore provided. The production process is used for producing the diaphragm one-way valve. Since the limiting ring table and the fixing portion can limit the magnet in the first hole segment, the magnet is prevented from dislocating or falling out, and therefore failure of the diaphragm one-way valve is prevented.

Description

technical field [0001] The invention relates to the field of one-way valves, in particular to a valve seat, a diaphragm-type one-way valve, and a production process for the diaphragm-type one-way valve. Background technique [0002] Check valves are widely used in the field of refrigeration equipment. The traditional one-way valve is usually provided with a movable valve core and a fixed valve seat, the valve seat has a valve seat hole for the flow of gas, when the air flow moves in one direction, the valve core moves away from the valve seat so that No sealing effect is provided, and the valve core is driven when the air flow moves in the other direction, and the valve core finally moves to the position of blocking the valve seat hole. At this time, the one-way valve is blocked, and the air flow cannot circulate, realizing the one-way interception effect. Effect. There is a diaphragm type check valve in the prior art check valve. The advantage of the diaphragm check valv...
