Description

Technical Field

[0001] The utility model relates to the technical field of valve connection devices, and is a valve handwheel connection device. Background Technique

[0002] Valves mainly play a role in control and regulation in natural gas production devices. Employees often open and close various valves in the process flow according to production needs during daily operations. With the increase in the types of natural gas products, the process flow has become increasingly complex, and the operation difficulty for employees has also increased accordingly. Some valves in the natural gas production device area are equipped with valve insulation boxes of different types and sizes due to cold insulation or heat insulation requirements. The main functions are, first, to prevent the loss of cold or heat of the pipeline, resulting in an increase in the load of the production device; second, to effectively prevent the valve from being damaged by external mechanical forces, the atmosphere, sunlight, and corrosive gases; third, to meet the requirements of visual management in the natural gas production device area, with a clean appearance, improving the working cold and hot environment of employees, and preventing personnel from being scalded or frozen. The current problem is that the height of the valve insulation box exceeds the connection point of the ball valve handle, resulting in the inability to install the ball valve handle. Even if some ball valves are installed with handles, due to being too close to the insulation box, the valves cannot be opened or closed. When there is an emergency condition in the device area that requires process switching, the lack of a handle or the inability to open and close will cause immeasurable losses to the safe production of the natural gas production device. Summary of the Invention

[0003] The utility model provides a valve handwheel connection device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problem that the installation of an external insulation box on the existing valve makes the handle inconvenient to rotate or even unable to install the handle, resulting in a safety hazard in the inability to perform opening and closing operations.

[0004] The technical solution of the utility model is realized by the following measures: A valve handwheel connection device includes a body and a handle joint. The upper end of the body is integrally provided with a handle joint, the outside of the handle joint is matched with the handle operation end, the lower end of the body is provided with a valve interface opening downward, and the shape of the valve interface matches the outside of the valve.

[0005] The following is a further optimization or / and improvement of the above-mentioned technical solution of the utility model:

[0006] Preferably, a through installation hole is provided in the upper part of the handle joint, and a handle fixing pin is provided in the installation hole.

[0007] Preferably, a fastening structure capable of fixing the valve and the body is provided on the body.

[0008] Preferably, the fastening structure includes a setscrew. A through fixing hole is provided on the body corresponding to the position of the valve interface, and the setscrew is installed in the fixing hole.

[0009] Preferably, the setscrew is a countersunk head screw.

[0010] The utility model has a reasonable and compact structure and is convenient to use. It is installed on a valve through a set valve interface to extend the end of the valve, and the original handle of the valve can be installed on the handle joint, which can solve the problem that it is inconvenient to install or rotate the handle in a narrow space, resulting in safety hazards in an emergency situation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Appendix Figure 1 It is a schematic perspective view of an embodiment of the utility model.

[0012] The codes in the drawings are respectively: 1 is the body, 2 is the handle joint, 3 is the valve interface, 4 is the mounting hole, and 5 is the fixing hole. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The utility model is not limited by the following embodiments, and the specific implementation manner can be determined according to the technical solution of the utility model and the actual situation.

[0014] In the utility model, for the convenience of description, the description of the relative position relationship of each component is carried out according to the layout mode of the attached drawings of the specification. For example, the position relationships such as front, rear, upper, lower, left, and right are determined according to the layout direction of the attached drawings of the specification. Figure 1 The following will further describe the utility model in conjunction with the embodiments and the drawings:

[0015] The following will further describe the utility model in conjunction with the embodiments and the drawings:

[0016] Embodiment 1: As shown in Figure 1 shown, the valve handwheel connecting device includes a body 1 and a handle joint 2. The handle joint 2 is integrally provided at the upper end of the body 1. The outer side of the handle joint 2 is matched with the handle operating end. The lower end of the body 1 is provided with a valve interface 3 opening downward, and the shape of the valve interface 3 is matched with the outer side of the valve.

[0017] When in use, the valve interface 3 of the body 1 is sleeved on the valve, and then the original handle of the valve is installed on the handle joint 2, so that the normal installation and use of the handle can be realized, and the function of normally installing the handle in a narrow space can be achieved. There is no need to use other tools to rotate the valve, and it can be installed on each valve in a narrow space where it is inconvenient to install and rotate the handle, which can solve the problems of safety hazards and losses caused by the lack of a handle or the inability to switch on and off when there is an emergency working condition in the device area and the process needs to be switched.
