Description

A butterfly valve control handle

technical field

The utility model relates to the technical field of butterfly valve accessories, in particular to a butterfly valve control handle.

Background technique

Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve that can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. The handle butterfly valve is a kind of butterfly valve. The handle butterfly valve is simple in structure, small in size and light in weight. It is composed of only a few parts, and it can be opened and closed quickly by rotating 90°. The operation is simple. It has good fluid control characteristics. The control handle is a handle used to control the opening and closing state of the handle butterfly valve. The existing butterfly valve control handle presses the handle to keep the limit insert away from the matching toothed plate, and then the handle can drive the disc plate. Rotation, the handle does not have a limit mechanism, so that when the handle is not in use, the operator may easily touch the handle by mistake, so that the handle rotates, and the limit insert on the handle is far away from the matching tooth plate, thus affecting the opening of the butterfly valve.

Please refer to Figures 1-4, an embodiment provided by the present invention: a butterfly valve control handle, including an installation sleeve 3, a first handle 4, a second handle 8, a support handle 9 and a limit piece 11. One end of the first handle 4 is installed with the installation sleeve 3, and the side of the first handle 4 away from the one end of the installation sleeve 3 is installed with a limiting piece 11, and one end of the first handle 4 away from the installation sleeve 3 is far away from the limiter. One side of the position piece 11 is hinged with a supporting handle 9, the bottom of the first handle 4 is mounted with a first hinge shaft 5, and the bottom of the first hinge shaft 5 is hinged with a second handle 8, and the second handle 8 A limiting insert 7 is installed on one end of the top close to the mounting sleeve 3 , and limiting holes 10 are evenly arranged inside the limiting sheet 11 .

In this implementation:

Further, a mounting hole 15 is provided inside the supporting handle 9 , and a limiting rod 16 is installed inside the mounting hole 15 to cooperate with the limiting hole 10 , and the limiting rod 16 is away from one end of the limiting piece 11 A pull plate 18 is installed, and a telescopic spring 17 is sleeved on the outer side of the limit insertion rod 16. One end of the telescopic spring 17 is connected to the support handle 9, and the end of the telescopic spring 17 away from the support handle 9 is connected to the pull plate 18. Connecting, by inserting the limit rods 16 on the support handle 9 into the different limit holes 10 on the limit piece 11, the inclination angle of the support handle 9 can be adjusted, so that the support handle 9 can be The handle 9 is adjusted to a position convenient for the operator to use, and the device is more convenient and comfortable to use.

Further, the end of the top of the second handle 8 away from the limiting insert 7 is hinged with a second limiting rod 14 , and the top of the second limiting rod 14 is hinged with a second hinge shaft 13 , and the top of the second hinge shaft 13 is hinged A first limit rod 12 is hinged, and one end of the first limit rod 12 away from the second hinge shaft 13 is hinged with the first handle 4. When the device is not in use, the first limit rod 12 and the second limit rod 14 It is blocked between the first handle 4 and the second handle 8. When the operator accidentally touches the second handle 8, the second handle 8 is blocked by the first limit rod 12 and the second limit rod 14. It cannot be rotated directly, so as to avoid operator errors affecting the opening and closing state of the butterfly valve.

Further, a return spring 6 is installed at the end of the bottom of the first handle 4 away from the installation sleeve 3, and the end of the return spring 6 away from the first handle 4 is connected with the second handle 8, and the elastic action of the return spring 6 can Help the second handle 8 reset.

Further, the end of the installation sleeve 3 away from the first handle 4 is provided with a nut installation hole 2, and the inner thread of the nut installation hole 2 is installed with a scale indicating nut 1, and the scale indicating nut 1 indicates the scale on the matching tooth plate, It can help the operator to know the degree of opening and closing of the butterfly valve.

Further, the bottom of the second handle 8 is evenly provided with finger grooves, which is convenient for pressing the second handle 8 .

Working principle: When in use, install the device on the butterfly valve, and connect the installation sleeve 3 to the butterfly rod. When the opening and closing state of the butterfly valve needs to be adjusted, the operator can push the second hinge shaft 13 first, so that the second hinge shaft 13 Drive the first limit rod 12 and the second limit rod 14 to rotate, so that a certain inclination angle is generated between the first limit rod 12 and the second limit rod 14 and the first handle 4 and the second handle 8 respectively As shown in FIG. 2, the second handle 8 can be rotated, and then the operator can hold the first handle 4 with his palm, hold the second handle 8 with his fingers, and his hand can rest on the supporting handle 9. The support handle 9 supports the operator's hand to prevent his hand from slipping off the first handle 4. The operator presses the second handle 8 so that the second handle 8 is connected to the first hinge axis along the operator's hand. The hinge position of 5 is the rotation of the center of the circle, so that the limit insert 7 is far away from the matching tooth plate, so that the whole device can be rotated, and the butterfly valve can be opened and closed by the first handle 4 and the installation sleeve 3 to drive the butterfly rod to rotate. To adjust, loosen the second handle 8, the elastic action of the reset spring 6 makes it push the second handle 8 to rotate and reset, so that the limit insert 7 is re-inserted into the tooth plate on the matching tooth plate, thereby completing the adjustment process , when the second handle 8 is reset, the second handle 8 drives the second limit rod 14 to reset, so that the first limit rod 12 and the second limit rod 14 are perpendicular to the first handle 4, and the first limit rod 12 and the second limit rod 14 are blocked between the first handle 4 and the second handle 8. When the operator accidentally touches the second handle 8, the second handle 8 is affected by the first limit rod 12 and the second handle 8. The blocking of the two limit rods 14 cannot be directly rotated, so as to avoid the operator's misoperation to affect the opening and closing state of the butterfly valve. lever 16, so that the pull plate 18 stretches the telescopic spring 17, and pulls the limit insert rod 16 out of the limit hole 10, and releases the limit insert rod 16 from the limit of the support handle 9, and then the operator can push To support the handle 9, make the support handle 9 rotate along its hinged position with the first handle 4 as the center of the circle. The elastic action of the position insertion rod 16 makes it pull the pull plate 18 to reset, so that the pull plate 18 pushes the limit insertion rod 16 to move, and pushes the limit insertion rod 16 into the corresponding limit hole 10 on the limit piece 11, The position insertion rod 16 limits the position of the support handle 9 , thereby fixing the position of the support handle 9 and completing the adjustment process of the support handle 9 .

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principle of the present utility model, any modifications, equivalent replacements, improvements, etc. made shall be included within the protection scope of the present utility model.
