As shown in fig. 1 and 2, the diaphragm valve opening degree adjusting device of the present disclosure includes a connecting member 1 and an adjusting mechanism.
One end of the connecting piece 1 is connected with the valve rod, and an adjusting channel 11 is arranged in the connecting piece 1. The connection between the connecting piece 1 and the valve rod can be realized by screw connection or pin connection and the like. The connecting piece 1 can drive or drive the valve rod to move, so that the opening degree of the diaphragm valve is adjusted by adjusting the position of the valve rod. The regulating channel 11 has a stopper therein. The adjustment channel 11 extends generally along the length extension of the connection piece 1, and both ends of the adjustment channel 11 are open. The limiting part can be a bulge or a boss, for example.
The adjusting device comprises an adjusting member 2, a support member 3 and an elastic member 4. The adjusting piece 2 is provided with a matching part 21 matched with the limiting part. The fit between the fitting portion 21 and the stopper portion may be, for example, a fit between the circumferential projection and the boss, or a snap fit. The adjusting piece 2 can be retained in the adjusting channel 11 by the engagement between the engaging portion 21 and the retaining portion.
The support member 3 is fixedly connected to the end of the adjusting member 2 adjacent to the connection of the connecting member 1 to the valve stem. The fixed connection between the support member 3 and the adjusting member 2 can be realized by a threaded connection or an integral molding.
The elastic member 4 is located in the adjustment passage 11, and the elastic member 4 is located between the fitting portion 21 and the support member 3 to provide the adjustment member 2 with a force in a direction toward the fitting portion 21. The elastic member 4 may be a spring or a leaf spring, for example. The elastic element 4 may continuously provide a force to the adjustment element 2 such that the adjustment element 2 exerts a force on the support element 3 towards the adjustment channel 11 when not subjected to an external force.
The diaphragm valve opening degree adjusting device disclosed by the utility model can have a locking state and an adjusting state.
In the locked state, the matching portion 21 of the adjusting member 2 matches with the limiting portion of the connecting member 1, and the supporting member 3 enters into the end of the adjusting passage 11 of the connecting member 1, which is matched with the valve stem. Under the supporting action of the supporting piece 3 on the inner wall of the adjusting channel 11, the end part of the connecting piece 1 expands, so that the connecting piece 1 and the valve rod are locked, and the opening degree of the diaphragm valve cannot be adjusted by adjusting the position of the connecting piece 1.

Acting force towards the valve rod is applied to the adjusting piece 2 in the adjusting channel 11 through a hexagon wrench, and the supporting piece 3 can be pushed out of the adjusting channel 11, so that the diaphragm valve opening adjusting device is converted into an adjusting state from a locking state. After the support 3 is pushed out of the adjusting channel 11, the position of the connecting piece 1 in the diaphragm valve can be adjusted by a hexagon wrench, so that the opening degree of the diaphragm valve is adjusted. After the adjustment is completed, the hexagonal wrench is taken out of the adjusting channel 11, the diaphragm valve opening adjusting device is converted into a locking state from the adjusting state under the action of the elastic piece 4, the supporting piece 3 enters the adjusting channel 11 again, and the connecting piece 1 and the valve rod are locked again. Therefore, the diaphragm valve opening adjusting device can adjust the opening through a single hexagonal wrench.
The coupling member 1 of the diaphragm valve opening degree adjustment apparatus of the present disclosure is supported by the support member 3 to assume an end-expanded state, so that the coupling member 1 is locked with the valve stem. Adjusting part 2 can drive support piece 3 and break away from regulation passageway 11 when receiving the exogenic action for the one end that connecting piece 1 is connected with the valve rod resumes to original state by the state of expanding, thereby the position of valve rod is changed to the position of accessible adjustment connecting piece 1, realizes the regulation of diaphragm valve opening. After the diaphragm valve opening is adjusted, the adjusting part 2 is driven by the elastic part 4 to move the supporting part 3, so that the connecting part 1 is in an expanded state again.
The diaphragm valve opening adjusting device can complete the adjustment of the diaphragm valve opening through a single operation tool, and is convenient and quick to operate.
