[0036] The mounting lug plate 5 is arranged at the bottom of the support seat 1 and is used for fixed connection with the valve member support.

[0037] In one practicable manner, Figure 1 As shown, a second mounting hole is arranged on the mounting ear plate 5, and a fastening bolt is arranged in the second mounting hole to fix the support seat 1 and the valve member support.

[0038] Specifically, one of the assembly holes on the valve support and multiple assembly holes on the connecting flange installed with the pipe fitting are selected, one of the assembly holes is selected to correspond to the second installation hole, and fastening bolts are set in the assembly hole and the second installation hole to install the support seat 1.

[0039] It should be noted that one or two mounting lugs 5 are provided at the bottom of the support seat 1 to adapt to the installation environment of different valve components.

[0041] The portion of the locking member 2 inserted into the first mounting hole is a cylindrical structure, and therefore the locking member 2 can rotate in the first mounting hole. After the support seat 1 is fixedly connected to the valve member support, the locking member 2 is adjusted to rotate in the first mounting hole according to the valve disc position of the valve member, so that the hook 3 corresponds to the valve disc position. After the locking member 2 is inserted downward, the hook 3 hooks the edge of the valve disc and moves downward to limit the rotation of the valve disc and lock the valve member.

[0042] The limiting unit at least includes a first limiting portion and / or a second limiting portion, the first limiting portion and the second limiting portion are inserted into the side of the support seat 1, the first limiting portion or the second limiting portion is inserted in the support seat 1, and the end is abutted against the locking member 2, and the locking member 2 is limited in the vertical direction through the friction between the first limiting portion or the second limiting portion and the outer surface of the locking member 2 to prevent the valve member from being accidentally touched and vibrated to cause free opening.

After the locking member 2 is installed, the eccentric protrusion 4 is rotated so that the contact point between the eccentric protrusion 4 and the locking member 2 is rotated from the small diameter arc segment 41 to the large diameter arc segment 42. The friction between the eccentric protrusion 4 and the locking member 2 can prevent the valve member from being accidentally touched or vibrated to cause free opening.

[0046] Specifically, Figure 3 and Figure 4 As shown, when the small diameter arc segment 41 corresponds to the position of the locking member 2, the locking member 2 can be adjusted up and down. When the large diameter arc segment 42 corresponds to the position of the locking member 2, the large diameter arc segment 42 abuts against the locking member 2, thereby limiting the upward and downward adjustment of the locking member 2.
