Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] see Figure 1-2 : An embedded valve plate check valve 3, including a sealing plate 1 and a valve plate 1, the outer ring of the sealing plate 1 has a uniform tooth-shaped gap, which is used for fixing and valve sealing when the injection plastic is vulcanized after being bonded to the valve plate. The seal between the sheet and the sealing plate and the seal with the periphery; there is a hole in the middle for the passage of liquid or gas. The sealing plate 1 is made of stainless steel with a thickness of about 0.5-1.5.

[0021] The outer ring of the valve plate 2 has a tooth-shaped gap corresponding to the outer ring of the sealing plate, and there is an arc-shaped cut in the middle. The arc-shaped cut makes the middle of the valve plate form a shrapnel 4 that can bounce off under force; the valve in the middle of the arc-shaped cut of the valve plate 2 On the sh...

Abstract

The invention relates to a one-way valve with an embedded valve plate. The one-way valve with the embedded valve plate comprises a sealing plate and the valve plate; uniform tooth-shaped gaps are formed in an outer ring of the sealing plate, and a hole is formed in the middle of the sealing plate; tooth-shaped gaps corresponding to the outer ring of the sealing plate are formed in an outer ring of the valve plate, and an arc notch is formed in the middle of the valve plate; the arc notch enables an elastic piece capable of being bounced off by stress to be formed in the middle of the valve plate; the sealing plate is bonded with the valve plate; the tooth-shaped gaps on the outer circle correspond to each other, and are fixed through injection molding vulcanization; and the diameter of the hole in middle of the sealing plate is smaller than the diameter of the elastic piece in middle of the valve plate. A force adjusting opening is formed in a valve plate body in the middle of the arc notch of the valve plate. The one-way valve is mounted in an existing pressing plate of a pipe to realize one-way flowing without adding parts.

Description

technical field [0001] The invention belongs to an automobile air conditioner, in particular to a one-way valve for flow direction control in an automobile air conditioner thermal management system. Background technique [0002] The check valve is a part of the thermal management system of the car. It is widely used in the heat pump system and the battery cooling system. Its main function is to control the flow of the refrigerant. [0003] At present, the check valves used in the refrigerant pipeline in the thermal management system of automobiles mainly include welded type, pressure plate type, and threaded type. Among them, the welded type belongs to the first generation of check valve, and the valve body is sealed by argon arc welding. Before the argon arc welding, the fixed-length aluminum tube needs to be welded by flame; The outlet is connected to the pipeline through a separately designed pressure plate, which can be used on a platform. [0004] The second-generatio...
