Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel pipeline gas self-closing valve. Background Art

[0002] The pipeline gas self-closing valve is a device installed on the pipeline of the low-pressure gas system. When the pipeline gas supply pressure is under-pressure or over-pressure, it can automatically close without electricity or other external power, and must be opened manually. It is suitable for pipeline natural gas, liquefied petroleum gas, and artificial coal gas. The basic principle of the pipeline gas self-closing valve is to magnetize the permanent magnetic material according to the design requirements to make a multi-pole permanent magnetic linkage mechanism with permanent memory, identify the changes in the gas pressure parameters passing through it, and automatically close the valve when it exceeds the safety set value to cut off the gas source.

[0003] Under normal circumstances, the upper end button of the pipeline gas self-closing valve is in a suspended pressure-waiting state. During use, the button in the suspended pressure-waiting state is sometimes accidentally touched by external objects, causing the button to close and the gas to be cut off, causing certain inconvenience to the user. Therefore, how to design a new type of pipeline gas self-closing valve has become a problem that we currently need to solve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a novel pipeline gas self-closing valve to solve the problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new pipeline gas self-closing valve, comprising a self-closing valve body and a lifting button arranged on the self-closing valve body, a buffer is fixedly installed inside the self-closing valve body, a hollow ring is fixedly installed on the telescopic end of the buffer pointing upward vertically, and an anti-collision plate is arranged on the top of the hollow ring;

[0006] An insertion rod is fixedly installed at the bottom of the anti-collision plate, a slot matched with the insertion rod is opened inside the hollow ring, a spring is fixedly installed inside the hollow ring, a moving block is fixedly installed at one end of the spring, a limiting rod is fixedly penetrated inside the moving block, and a limiting groove matched with the limiting rod is opened inside the insertion rod.

[0007] Preferably, a push switch and a buzzer are respectively installed on the outer surface of the self-closing valve body, the push switch is electrically connected to the buzzer, the buzzer can be connected to an external power supply through an electric wire, the push switch is arranged below the lifting button, and the lifting button falls so that it can touch the lifting button.

[0008] Preferably, one end of the limiting rod passes through the outside of the hollow ring and is fixedly connected to a pull ring.

[0009] Preferably, a rubber anti-skid pad is fixedly mounted on the outer side of the anti-collision plate.

[0010] Preferably, an end of the limiting rod away from the pull ring is provided with a guide angle inclined upward.

[0011] Preferably, sliding blocks are fixedly mounted on opposite sides of the moving block, and a sliding groove matched with the sliding blocks is provided inside the hollow ring.

[0012] The utility model provides a new pipeline gas self-closing valve, which has the following beneficial effects:

[0013] First: during use, when an external object accidentally touches the handle, the anti-collision plate outside the handle can buffer the impact force through the buffer. The accidental touch and bump with a force less than the elastic force of the buffer will not cause the handle to close, thereby reducing the situation where the handle is closed due to accidental touch. In an emergency, the user presses the anti-collision plate with a force greater than the buffer. The anti-collision plate can squeeze the buffer and push the handle to close, cutting off the gas, thereby not affecting the normal use function of the self-closing valve.

[0014] Second, when in use, once the handle falls and closes, the handle may touch the push switch, and the push switch may activate the buzzer to sound an alarm.

[0015] Thirdly, when the anti-collision plate is damaged, the user can pull the pull ring, which can drive the limit rod to move, and the limit rod can drive the moving block to squeeze the spring and separate from the limit groove on the plug rod, so that the anti-collision plate can be quickly removed for replacement.

[0024] Please refer to Figure 2 and Figure 3 The bottom of the anti-collision plate 5 is fixedly installed with an insertion rod 6, the interior of the hollow ring 4 is provided with a slot adapted to the insertion rod 6, the interior of the hollow ring 4 is fixedly installed with a spring 7, one end of the spring 7 is fixedly installed with a moving block 8, the interior of the moving block 8 is fixedly penetrated with a limiting rod 9, and the interior of the insertion rod 6 is provided with a limiting groove adapted to the limiting rod 9. One end of the limiting rod 9 passes through the exterior of the hollow ring 4 and is fixedly connected with a pull ring 12, which can facilitate the user to pull the limiting rod 9.

[0025] Please refer to Figure 2 and Figure 3 The end of the limit rod 9 away from the pull ring 12 is provided with a guide angle 14 inclined upward. When installing the anti-collision plate 5, the insertion rod 6 on the anti-collision plate 5 can push the limit rod 9 to move through the guide angle 14, so that the anti-collision plate 5 and the hollow ring 4 can be quickly installed. Slide blocks 15 are fixedly installed on the opposite sides of the moving block 8. The interior of the hollow ring 4 is provided with a slide groove adapted to the slide block 15.

[0027] The working process of the utility model is as follows: during use, when an external object accidentally touches the lifting button 2, the anti-collision plate 5 outside the lifting button 2 can buffer the impact force through the buffer 3, and the accidental touch and bump with a force smaller than the elastic force of the buffer 3 will not cause the lifting button 2 to be closed, thereby reducing the situation where the lifting button 2 is closed due to accidental touch.
