Description

Technical Field

[0001] The utility model relates to a water seal structure, in particular to a cylindrical positive and negative water seal structure. Background Art

[0002] The working principle of water seal is to form a closed space at the contact point between the rotating ring and the stationary ring, and use fluids such as water or oil as the medium to achieve the purpose of sealing. Common working principles include: dynamic seal, static seal, skeleton oil seal, etc. At present, water seals are generally replaced by breathing valves, but the working pressure of breathing valves will deviate after long-term operation, and regular inspection is required.

[0003] In order to solve the above problems, the purpose of the utility model is to provide a cylindrical positive and negative water seal structure.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a cylindrical positive and negative water seal structure, including a closed cylinder and a water inlet and a water outlet arranged up and down on one side of the cylinder, a vertical partition is arranged in the center of the cylinder, and the partition only leaves a gap structure at the bottom, so that there are enough cavities connected through the gap structure at the bottom, the lower end of the first inlet pipe extends to the bottom of the left cavity of the cylinder, and the side wall of the first inlet pipe outside the cylinder is provided with a second inlet pipe connected to the top of the right cavity of the cylinder, the lower end of the first outlet pipe extends to the middle part of the right cavity of the cylinder, and the second outlet pipe connected to the side wall of the first outlet pipe outside the cylinder is connected to the top of the left cavity of the cylinder.

[0005] Furthermore, a connecting flange is provided at the top of the cavity connected to the first inlet pipe.

[0006] Furthermore, the cylinder is welded from stainless steel.

[0007] Furthermore, the upper end of the first outlet pipe is bent downward.

[0008] Furthermore, the lower end of the first outlet pipe is higher than the lower end of the first inlet pipe.

[0009] Furthermore, each inlet and outlet pipe is fixedly connected to the cylinder body by welding.

[0010] The advantages of the utility model are: the utility model is a preferred alternative product for the breathing valve, and the utility model has an improved structure: that is, the lower end of the first inlet pipe extends to the bottom of the left cavity of the cylinder, and the side wall of the first inlet pipe outside the cylinder is provided with a second inlet pipe connected to the top of the right cavity of the cylinder, the lower end of the first outlet pipe extends to the middle part of the right cavity of the cylinder, and the second outlet pipe connected to the side wall of the first outlet pipe outside the cylinder is connected to the top of the left cavity of the cylinder. As long as the water level in the cylinder is appropriate, the internal pressure will remain stable during operation, which can effectively ensure the water sealing effect and enable the container to maintain a certain stable pressure.

[0015] like Figure 1-3 As shown, a cylindrical positive and negative water seal structure includes a sealed cylinder 1 and a water inlet 2 and a water outlet 3 arranged up and down on one side of the cylinder 1, a vertical partition is arranged in the center of the cylinder 1, and the partition only leaves a gap structure 4 at the bottom, so that two cavities are connected through the gap structure 4 at the bottom, the lower end of the first inlet pipe 5 extends to the bottom of the left cavity of the cylinder 1, and the side wall of the first inlet pipe 5 outside the cylinder 1 is provided with a second inlet pipe 6 connected to the top of the right cavity of the cylinder 1, the lower end of the first outlet pipe 7 extends to the middle part of the right cavity of the cylinder 1, and the second outlet pipe 8 connected to the side wall of the first outlet pipe 7 outside the cylinder 1 is connected to the top of the left cavity of the cylinder 1.

[0016] In addition, a connecting flange 9 is provided at the top of the cavity connected to the first inlet pipe 5. The cylinder 1 is welded with stainless steel. The upper end of the first outlet pipe 7 is bent downward, and the lower end of the first outlet pipe 7 is higher than the lower end of the first inlet pipe 5. Each inlet and outlet pipe is fixedly connected to the cylinder 1 by welding.

[0017] Working principle of this utility model:

[0018] The first inlet pipe 5 is connected to the pressure container (i.e., the tank body), and the first outlet pipe 7 is connected to the gas supply container. When the pressure is positive, the gas enters the tank body through the first outlet pipe 7 and passes through the cylinder body 1-the second inlet pipe 6-the first inlet pipe 5 in sequence (the pressure of the passage of the first outlet pipe 7-the second outlet pipe 8-the cylinder body 1-the first inlet pipe 5 will be higher and impassable). When the pressure is negative, the gas in the container is discharged from the first inlet pipe 5-the cylinder body 1-the second outlet pipe 8-the first outlet pipe 7 (similarly, the pressure of the passage of the first inlet pipe 5-the second inlet pipe 6-the cylinder body 1-the first outlet pipe 7 will be higher and impassable).

[0019] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
