Detailed Description

A check valve having a unitary piston-type cartridge according to the present invention will be further described with reference to fig. 1-3.

Referring to fig. 1-3, the check valve with an integral piston type valve core according to the present embodiment includes a valve body 1, and connectors 2 installed at two ends of the valve body 1, and is characterized in that a valve seat 101 is disposed in the valve body 1, a piston type valve core 3 is installed on the valve seat 101, and the piston type valve core 3 includes a connecting rod 301, a sealing gasket 302 disposed at one end of the connecting rod 301, and a limiting block 303 disposed on the connecting rod 301; sealing is realized by matching the sealing gasket 302 with the valve seat 101, and the limiting block 303 can play a role in limiting and fixing the connecting rod 301.

Referring to fig. 2, a flow guiding hole 1011 and a mounting hole 1012 are formed in the valve seat 101, and the connecting rod 301 is mounted in the mounting hole 1012; liquid communication is achieved through the flow guide holes 1011.

Referring to fig. 1, the connector 2 includes a clamping cap 201 installed on a valve body 1, and a clamping jaw 202 installed on the clamping cap 201, an inner end face 102 is arranged in the valve body 1, a sealing ring 4 is installed on the inner end face 102, an installation table 103 is also arranged in the valve body 1, a limiting sleeve 5 is installed on the installation table 103, the sealing ring 4 is installed on the limiting sleeve 5, an outer clamping groove 104 is arranged on the valve body 1, an outer clamping head 2011 matched with the outer clamping groove 104 is arranged on the clamping cap 201, a clamping table 2012 is arranged on the clamping cap 201, and an inner clamping head 2021 matched with the clamping table 2012 is arranged on the clamping jaw 202; increase the leakproofness of valve through sealing washer 4, through outer draw-in groove and outer dop cooperation, will block the cap joint on the valve body, through the cooperation of ka tai and interior dop with the jack catch joint on the card cap, need not ultrasonic bonding, it is more convenient to install.
