Description

Technical Field

[0001] This utility model relates to the field of air release valve technology, specifically an air release valve for a water supply pipeline. Background Technology

[0002] When the gas pressure in the water supply pipe is too high, the gas will rise up along the pipe and eventually accumulate at the highest point. The air vent valve is usually installed at the highest point of the water supply pipe. However, the air vent valves used in water supply pipes in the prior art cannot adjust the air intake and exhaust volume, which makes it impossible to quickly raise the pressure in the pipe to the normal level under low pressure. Therefore, those skilled in the art have provided an air vent valve for water supply pipes to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a water supply pipeline air vent valve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water supply pipeline air vent valve, comprising a mounting shell, a valve seat fixedly connected to the bottom of the mounting shell, a threaded pipe connected to the bottom of the valve seat, a perforated water inlet pipe connected to the bottom of the threaded pipe, a floating block placed inside the mounting shell, a sealing ring fixedly connected to the top of the floating block, a sealing plug fixedly connected to the top of the sealing ring, and the sealing plug sealingly penetrating the top inner wall of the mounting shell.

[0005] As a further improvement of this utility model: a transparent shell is fixedly embedded on the outer wall of the mounting shell, and the sealing plug is inserted through the air hole.

[0006] As a further improvement of this utility model: the top of the sealing ring and the top inner wall of the mounting shell are sealed together, and the floating block is located above the threaded pipe.

[0007] As a further improvement of this utility model: the hollow water inlet pipe and the threaded pipe are connected, and the threaded pipe is connected to the mounting shell.

[0008] As a further improvement of this utility model: the floating block has a hollow cavity inside, and the floating block is made of rubber.

[0009] As a further improvement of this utility model: multiple rectangular holes are arranged in a ring on the outer wall of the hollow water inlet pipe, and the diameter of the hollow water inlet pipe is smaller than the diameter of the threaded pipe.

[0010] As a further improvement of this utility model: the diameter of the threaded tube is smaller than the diameter of the mounting shell, and the outer wall of the floating block is in contact with the inner wall of the mounting shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The threaded pipe can be inserted into the water supply pipe for threaded installation. Water from the water supply pipe can enter the hollow inlet pipe and the threaded pipe. When the water enters the mounting shell, it can lift the float block and the sealing ring. After the sealing ring rises, it can drive the sealing plug into the air hole for sealing. When the amount of gas in the pipe is too small, the sealing plug, sealing ring, and float block will descend. At this time, the air hole will be fully opened, and a large amount of gas will enter the water supply pipe to stabilize the air pressure.

[0012] This invention is simple to use. The air pressure in the water supply pipe will cause the sealing ring and sealing plug to drop in stages. This allows the gas to be slowly discharged through the gap between the sealing plug and the air hole only when the sealing ring drops. When the sealing plug drops to the point of being completely separated from the air hole, the sealing plug can be fully opened. This allows the gas to quickly enter the mounting shell and the water supply pipe to restore the normal level. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 In this embodiment of the utility model, a water supply pipeline air vent valve, such as... Figure 1 As shown, the water supply pipe air vent valve of this embodiment includes a mounting shell 1. A valve seat 4 is fixedly connected to the bottom of the mounting shell 1. A threaded pipe 5 is connected to the bottom of the valve seat 4. A hollow water inlet pipe 6 is connected to the bottom of the threaded pipe 5. A float block 8 is placed inside the mounting shell 1. A sealing ring 9 is fixedly connected to the top of the float block 8. A sealing plug 3 is fixedly connected to the top of the sealing ring 9, and the sealing plug 3 seals through the top inner wall of the mounting shell 1.

[0017] In this embodiment, a transparent shell 2 is fixedly embedded on the outer wall of the mounting shell 1, and a sealing plug 3 is inserted through the air hole 7.

[0018] In this embodiment, the top of the sealing ring 9 is sealed and fitted to the top inner wall of the mounting shell 1, and the floating block 8 is located above the threaded tube 5.

[0019] In this embodiment, the hollow water inlet pipe 6 and the threaded pipe 5 are connected, and the threaded pipe 5 is connected to the mounting shell 1.

[0020] In this embodiment, a hollow cavity 10 is provided inside the floating block 8, and the floating block 8 is made of rubber.

[0021] In this embodiment, multiple rectangular holes are arranged in a ring on the outer wall of the hollow water inlet pipe 6, and the diameter of the hollow water inlet pipe 6 is smaller than the diameter of the threaded pipe 5.

[0022] In this embodiment, the diameter of the threaded pipe 5 is smaller than the diameter of the mounting shell 1. The outer wall of the float block 8 fits against the inner wall of the mounting shell 1. A hollow cavity 10 is opened inside the float block 8, which can reduce the weight of the float block 8 and make it easier for the float block 8 to float and rise. When the air pressure inside the mounting shell 1 is stable, the float block 8 will only drive the sealing ring 9 to descend and open the air hole 7. The gas will be slowly discharged through the gap between the air hole 7 and the sealing plug 3. This can be applied to the daily venting of water supply pipes.

[0023] The working principle of this utility model is as follows: the threaded pipe 5 can be inserted into the water supply pipe for threaded installation. Water can enter the water supply pipe through the hollow water inlet pipe 6 and the threaded pipe 5. When the water enters the mounting shell 1, it can lift the float block 8 and the sealing ring 9. After the sealing ring 9 rises, it can drive the sealing plug 3 into the air hole 7 for sealing. When the amount of gas in the pipe is too small, the sealing plug 3, the sealing ring 9, and the float block 8 will descend. At this time, the air hole 7 will be fully opened, and a large amount of gas will enter the water supply pipe to stabilize the air pressure.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
