Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses strong stability gate valve. Referring to fig. 1 and 2, a strong stability gate valve includes a valve body 1 and a valve cover 2 covering the valve body 1. Be equipped with valve rod 3 in valve body 1, the one end that valve rod 3 is close to valve body 1 is equipped with the valve plate that is used for opening and close the valve, and the other end of valve rod 3 inserts to the valve gap 2 in and is connected with handle 4. The operator can control the rotation of the valve plate by rotating the handle 4.

Referring to fig. 2 and 3, a placing groove 5 is formed in the handle 4, the placing groove 5 penetrates through the handle 4 and is further connected with a control rod 6 in the placing groove 5 in a sliding manner, a connecting rod 8 is fixedly connected to one end of the control rod 6 facing the valve rod 3, a connecting groove 7 for inserting the connecting rod 8 is formed in one side of the valve rod 3 facing the handle 4, the groove shape of the connecting groove 7 is the same as the interface shape of the connecting rod 8, and the connecting groove and the connecting rod 8 are rectangular. When connecting rod 8 inserts to spread groove 7 in, the staff can rotate handle 4, and the rotation of handle 4 drives control lever 6 and rotates, and control lever 6 will drive valve rod 3 and rotate to play the effect of opening and close of control flap.

Referring to fig. 2 and 3, a transverse groove 10 is further formed on the side surface of the handle 4 away from the valve body 1, a transverse block 9 is fixedly connected to one end of the control rod 6, the transverse block 9 can slide in the transverse groove 10, and a pull ring 18 is fixedly connected to one end of the transverse block 9 away from the control rod 6. When the staff will shift out connecting rod 8 from connecting groove 7, the staff accessible is held and is pulled ring 18 to 6 application of force of control lever, makes connecting rod 8 deviate from in the connecting groove 7, because there is the space between connecting rod 8 and the valve rod 3 this moment, when the staff continues to rotate handle 4, connecting rod 8 just can't drive valve rod 3 and rotate to this can play and avoid the staff mistake to touch handle 4 and drive valve rod 3 and take place the mistake and rotate. When the staff will change the operating condition of valve this moment, only need remove connecting rod 8 towards spread groove 7 once more, alright realize the rotation of control valve rod 3 once more. Because the one end that connecting rod 8 kept away from horizontal piece 9 is established to the circular arc end, when connecting rod 8 inserts again in connecting groove 7, insert in connecting groove 7 with the guide connecting block through the circular arc end.

Referring to fig. 3 and 4, a transverse block 9 is fixedly connected to one side of the connecting rod 8 away from the valve rod 3, a transverse groove 10 for placing the transverse block 9 is also formed in the handle 4, and the transverse groove 10 is communicated with the placing groove 5. The handle 4 is provided with a limiting block 11 which is fixedly connected with a notch of the transverse groove 10 and prevents the transverse block 9 and the control rod 6 from being separated from the handle 4, the limiting block 11 comprises a vertical rod 13 and a horizontal rod 12, the horizontal rod 12 is perpendicular to the vertical rod 13, one end of the vertical rod 13 is fixedly connected with the handle 4, and the other end of the vertical rod 13 is detachably connected with the horizontal rod 12. The side wall of the cross bar 12 is located right above the transverse groove 10, and when a worker pulls the pull ring 18, the control rod 6 cannot be separated from the handle 4 due to the presence of the cross bar 12. A magnetic member 14 is also fixedly connected to one side of the cross bar 12 facing the transverse groove 10, when a worker brings the magnetic member 14 into contact with the transverse block 9, the magnetic member 14 and the transverse block 9 attract each other, and a gap exists between the connecting rod 8 and the connecting groove 7.

Referring to fig. 3 and 4, a clamping groove 16 is formed in one side, close to the cross rod 12, of the vertical rod 13, a notch of the clamping groove 16 is located on a side wall of the vertical rod 13, the cross rod 12 is also fixedly connected with the cross rod 12 towards the side provided with the magnetic part 14 and can be inserted into a clamping block 15 in the clamping groove 16, and the edge length of one end, far away from the cross rod 12, of the clamping block 15 is greater than the edge length of one end, close to the cross rod 12, of the clamping block 15. When the engaging blocks 15 are inserted into the engaging grooves 16, the engaging blocks 15 cannot be separated from the vertical rods 13 in the vertical direction due to the design of the engaging blocks 15 with narrow top and wide bottom. And still fixedly connected with one deck rubber layer 17 on the inner wall of joint groove 16, elasticity and frictional force through rubber layer 17 to play the stability that further strengthens joint piece 15 and be located joint groove 16, make joint piece 15 be difficult for following the horizontal direction and deviate from in the joint groove 16.

The embodiment of the application discloses strong stability gate valve's implementation principle does: when the operating condition that the staff will change the valve, the staff only need press horizontal pole for connecting rod 8 inserts to spread groove 7 in, later the staff alright rotate handle 4, thereby reach control flap's operating condition.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
