Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valve connecting pipe fittings, in particular to an exhaust valve connecting pipe fitting which is convenient for inspection and maintenance. Background Art

[0002] An exhaust valve is a pipe device that is mainly used to discharge excess gas in a pipe or container to maintain the pressure balance inside the system. In a liquid pipeline, an exhaust valve can remove bubbles to prevent gas accumulation from causing pipe blockage or excessive pressure. In addition, an exhaust valve can also adjust the pressure inside the system to keep it within a set range.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the water supply pipeline is shut down for maintenance or the old pipeline network is repaired, a manhole needs to be set up to facilitate the entry and exit of personnel and equipment. The exhaust valve and the manhole in the prior art are usually set separately, and multiple inspection wells need to be set up, which increases the project investment and construction time. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an exhaust valve connecting pipe fitting which is easy to inspect and maintain.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] By adopting the above technical solution, the exhaust valve body exhausts the inside of the water supply pipe. When the water supply pipe needs to be inspected and repaired, the staff only needs to rotate the connecting pipe to make the connecting pipe disengage from the threaded through hole upward, and then release the fixing effect of multiple bolts on the upper flange and the lower flange, so as to remove the upper flange and the sealing plate from the mounting pipe. The staff can enter the water supply pipe through the mounting pipe for maintenance and inspection, eliminating the tedious operation of separately setting the exhaust valve and the manhole, thereby reducing the project investment and construction time.

[0008] Furthermore, an annular limiting plate is fixed to the bottom of the sealing plate.

[0009] By adopting the above technical solution, the annular limiting plate limits the position of the connecting pipe, preventing the connecting pipe from moving too much downward into the installation pipe, which is conducive to the normal use of the connecting pipe fitting.

[0010] Furthermore, an annular rubber sheet is embedded on the upper surface of the annular limiting plate.

[0011] By adopting the above technical solution, the annular rubber sheet is made of rubber material with good sealing performance. The connecting pipe cooperates with the annular limiting plate and presses against the annular rubber sheet, thereby enhancing the sealing between the annular limiting plate and the connecting pipe.

[0012] Furthermore, a plurality of booster rods are fixed to the side wall of the connecting pipe, and the plurality of booster rods are evenly distributed about the axis of the connecting pipe.

[0013] By adopting the above technical solution, the power-assisting rod makes it easier for workers to rotate the connecting pipe, making it convenient for workers to disassemble the connecting pipe and open the cover to perform maintenance and repair on the water supply pipe.

[0014] Furthermore, the inner diameter of the installation pipe is greater than or equal to 0.5m.

[0015] By adopting the above technical solution, the inner diameter of the installation pipe above 0.5m is convenient for the staff and equipment to enter and exit, which is conducive to the maintenance and repair of the water supply pipeline.

[0016] Furthermore, a branch pipe connected to the mounting pipe is fixed on the side wall of the mounting pipe, and a second valve gate is fixed on one end of the branch pipe away from the mounting pipe.

[0017] By adopting the above technical solution, the branch pipe and the second valve gate are set up, so that the connecting pipe is equipped with a new water outlet, which is convenient for adding user branches at a later time.

[0018] Furthermore, a support rod is fixed to the bottom of the second valve gate, and the lower end of the support rod is fixed to the side wall of the water supply pipe.

[0019] By adopting the above technical solution, the support rod supports and reinforces the second valve gate, thereby improving the stability of the second valve gate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, the exhaust valve body exhausts the inside of the water supply pipe. When the water supply pipe needs to be repaired, the staff only needs to rotate the connecting pipe to make the connecting pipe disengage upward from the threaded through hole, and then release the fixing effect of multiple bolts on the upper flange and the lower flange, so as to remove the upper flange and the sealing plate from the mounting pipe. The staff can enter the water supply pipe through the mounting pipe for maintenance and repair, eliminating the cumbersome operation of separately setting the exhaust valve and the manhole, reducing the project investment and construction time;

[0022] 2. In this application, the annular limiting plate limits the position of the connecting pipe, preventing the connecting pipe from moving too much downward into the installation pipe, which is conducive to the normal use of the connecting pipe fittings;

The sealing plate 4 is a circular plate-shaped structure, and the sealing plate 4 is arranged on the upper end of the mounting pipe 2, and is used to close the pipe opening at the upper end of the mounting pipe 2. The upper surface of the sealing plate 4 is penetrated with a threaded through hole 41. The upper flange 5 is an upper flange 5 commonly used in the prior art and applicable to the present embodiment, and the upper flange 5 is fixedly sleeved on the sealing plate 4, and the upper flange 5 and the lower flange 3 are fixed by a plurality of bolts 6. The connecting pipe 7 is a vertically arranged circular tubular structure, and the connecting pipe 7 is arranged on the sealing plate 4 and is threadedly connected to the threaded through hole 41. The first valve gate 8 is a first valve gate 8 commonly used in the prior art and applicable to the present embodiment, and the first valve gate 8 is fixed on the upper end of the connecting pipe 7. The exhaust valve body 9 is an exhaust valve body 9 commonly used in the prior art and applicable to the present embodiment. The exhaust valve body 9 is fixed to the upper end of the first valve gate 8 .

[0032] The exhaust valve body 9 exhausts the inside of the water supply pipe 1. When the water supply pipe 1 needs to be inspected and repaired, the staff only needs to rotate the connecting pipe 7 to make the connecting pipe 7 disengage from the threaded through hole 41 upward, and then release the fixing effect of multiple bolts 6 on the upper flange 5 and the lower flange 3, so as to remove the upper flange 5 and the sealing plate 4 from the mounting pipe 2. The staff can enter the water supply pipe 1 through the mounting pipe 2 for maintenance and inspection, eliminating the tedious operation of separately setting the exhaust valve and the manhole, thereby reducing the project investment and construction time.

[0033] In order to prevent the connecting pipe 7 from moving too much downward, an annular limit plate 10 is fixed at the bottom of the sealing plate 4.

[0037] The use principle of an exhaust valve connecting pipe fitting that is easy to inspect and maintain in the present embodiment is as follows: the exhaust valve body 9 exhausts the inside of the water supply pipe 1. When the water supply pipe 1 needs to be inspected and maintained, the staff only needs to rotate the connecting pipe 7 to make the connecting pipe 7 disengage from the threaded through hole 41 upward, and then release the fixing effect of multiple bolts 6 on the upper flange 5 and the lower flange 3, so as to remove the upper flange 5 and the sealing plate 4 from the mounting pipe 2. The staff can enter the water supply pipe 1 through the mounting pipe 2 for maintenance and inspection, eliminating the tedious operation of separately setting up the exhaust valve and the manhole, thereby reducing the project investment and construction period.
