Description

Technical Field

[0001] This utility model belongs to the field of gas transmission technology, specifically relating to a pressure balancing device for pipelines before and after a gas station valve. Background Technology

[0002] With the development of the industry, the demand for gas is increasing, and the pressure mechanism of pipeline gas transmission is constantly improving. For gas stations, due to the gas transmission pressure and the large inner diameter of the gas station's transmission pipeline, the valves are difficult to open due to the large pressure difference on both sides. Therefore, a pressure balancing device for the pipelines before and after the gas station valves is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a pressure balancing device for pipelines before and after a gas station valve. When the pressure inside the first main pipeline is too high, it pushes the ball valve inside the gas transmission pipe to move, thereby compressing the spring. The high-pressure gas inside the first main pipeline is released into the gas storage tank through the gas transmission pipe, thereby keeping the pressure on the left and right sides of the valve balanced, which facilitates the operation of the valve.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A pressure balancing device for pipelines before and after a gas station valve includes a first main pipeline, a valve, a second main pipeline, and a gas storage tank. The first main pipeline and the second main pipeline are respectively installed on the left and right sides of the valve. A gas transmission pipe is fixedly provided between the front side of the gas storage tank and the first and second main pipelines. A ball valve is slidably installed in each gas transmission pipe, and a spring matching the ball valve is fixedly installed in each gas transmission pipe. The ball valves and springs on the left and right sides are arranged in opposite directions.

[0006] Each gas pipe has a circular groove inside, and each gas pipe has a fixed spherical groove that matches the ball valve.

[0007] Both gas pipes are equipped with several speed reduction plates inside.

[0008] A pressure monitoring gauge is installed on the upper side of the gas storage tank.

[0009] Both of the gas pipelines are installed at an angle.

[0010] When the pressure inside the first main pipeline is too high, this utility model pushes the ball valve inside the gas transmission pipe to move, thereby compressing the spring. The high-pressure gas inside the first main pipeline is released into the gas storage tank through the gas transmission pipe, thereby keeping the pressure on the left and right sides of the valve balanced, which facilitates the operation of the valve.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, the present invention provides a pressure balancing device for pipelines before and after a gas station valve, comprising a first main pipeline 1, a valve 10, a second main pipeline 11, and a gas storage tank 12. The first main pipeline 1 and the second main pipeline 11 are respectively installed on the left and right sides of the valve 10. A gas transmission pipe 13 is fixedly provided between the front side of the gas storage tank 12 and the first main pipeline 1 and the second main pipeline 11. A ball valve 14 is slidably installed in each gas transmission pipe 13. A spring 15 matching the ball valve 14 is fixedly provided in each gas transmission pipe 13. The ball valve 14 and the spring 15 on the left and right sides are arranged in opposite directions.

[0019] Each gas pipe 13 has a circular groove 20 inside, and each gas pipe 13 has a spherical groove 21 that matches the ball valve 14.

[0020] When this invention is in use, when the gas pressure inside the first main pipe 1 increases, the gas inside the first main pipe 1 pushes the ball valve 14 inside the interconnected gas transmission pipe 13 to slide. During the movement of the ball valve 14, the spring 15 is compressed, and the high-pressure gas inside the first main pipe 1 is released into the gas storage tank 12 through the gas transmission pipe 13, thereby keeping the pressure inside the first main pipe 1 stable. Under the elastic action of the spring 14, the ball valve 14 is made to fit with the ball groove 21, thereby closing the gas transmission pipe 13. When there is too much gas stored in the gas storage tank 12, the pressure inside the gas storage tank 12 increases, thereby pushing the ball valve 14 inside the gas transmission pipe 13 on the other side to move, so that the gas inside the gas storage tank 12 flows into the second main pipe 11 through the gas transmission pipe 14, thereby keeping the pressure inside the gas storage tank 12 stable without the need for manual pressure relief.

[0021] When the pressure inside the first main pipeline is too high, this utility model pushes the ball valve inside the gas transmission pipe to move, thereby compressing the spring. The high-pressure gas inside the first main pipeline is released into the gas storage tank through the gas transmission pipe, thereby keeping the pressure on the left and right sides of the valve balanced, which facilitates the operation of the valve.

[0022] Several speed reduction plates 22 are fixedly installed inside both gas supply pipes 13 to slow down the gas passing through the gas supply pipes 13 and ensure the smooth operation of the device.

[0023] A pressure monitoring gauge 25 is installed on the upper side of the gas storage tank 12 to monitor the pressure inside the gas storage tank 12 and ensure the safe use of this device.

[0024] Both gas supply pipes 13 are inclined to facilitate gas inflow and outflow.

[0025] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
