Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a high-sealing valve. Background Art

[0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into: pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] Although the gas ball valve can effectively improve the control stability, under special circumstances, if the plug body cannot be rotated, the ball valve cannot be closed, and it is not convenient to control the size of the gas flow, and the air tightness is still insufficient, which poses a safety hazard. Moreover, the gas valve of the prior art is completely exposed to the outside without any safety protection device. Some children may still open the gas valve out of curiosity or carelessness, which is likely to cause a safety accident. Utility Model Content

[0004] The utility model aims to provide a high-sealing valve, which overcomes the shortcomings of the prior art. The ball is controlled to rotate by turning the handle to control the switch of the device, and the butterfly plate makes the sealing effect of the device better. At the same time, the natural gas flow rate can be adjusted more flexibly. When the ball cannot be closed, the regulating valve can also be turned to close the device. The spring is connected to the lower surface of the regulating valve, and the outer side of the lower end of the telescopic rod is connected to the inner surface of the spring, so that the telescopic rod cannot contact the regulating rod when not in use. In this way, even if others accidentally open the handle and turn the regulating valve, the device cannot be opened to allow the natural gas to flow. The utility model has the characteristics of good sealing effect, strong practicality and safe operation.

[0005] In order to solve the above problems, the technical solutions adopted by the utility model are as follows:

[0006] A high sealing valve, comprising

[0007] The control mechanism comprises an air intake pipe, a sleeve and a sphere, wherein the air intake pipe is provided with a sphere inside, and the top of the sphere is connected with the sleeve;

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model controls the rotation of the sleeve by turning the handle, thereby driving the ball to rotate, so as to control the switch and closing of the device. The butterfly plate makes the sealing effect of the device better, and at the same time, it is more convenient to adjust the natural gas flow rate. When the handle fails to close the device, the regulating valve can also be turned to close the device, thereby increasing the practicality of the device.

[0017] The utility model is connected to the lower surface of the regulating valve through a spring, and the outer side of the lower end of the telescopic rod is connected to the inner surface of the spring, so that the telescopic rod cannot touch the regulating rod when not in use.
