Description

Technical Field

[0001] The utility model relates to the technical field of valve splicing, and particularly relates to a valve for a quick-assembly pipeline component. Background Art

[0002] Pipe fittings are components used to connect and control the flow of fluids in a pipeline system, such as elbows, tees, crosses, etc. A joint is a key component for connecting pipe fittings to each other and to equipment. Common joints include flange joints, threaded joints, grooved joints, etc. There are various connection methods, including threaded connection, flange connection, welding connection, and grooved connection. These connection methods ensure a tight connection between pipe fittings and joints, preventing fluid leakage. The valve switch for pipe fitting connection is also an essential component, which can control the opening and closing of the flowing medium. As the terminal device of the pipeline system, the sprinkler head is widely used in fields such as fire protection, industry, and agriculture. The connection between the sprinkler head and the pipe network mostly adopts the joint connection method, that is, using accessories such as valves, joints, and pipe fittings to connect the sprinkler head and the pipe network to ensure that the sprinkler head can receive sufficient fluid pressure and spray evenly.

[0003] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: Some traditional pipeline connection methods (such as flange connection) require the cooperation of multiple steps and multiple components to complete;

[0004] For example, it is necessary to first weld the flange on the pipeline, and then connect the valve to the flange through bolts and gaskets. These steps are not only cumbersome but also require a certain level of technical skills and experience to ensure the installation quality. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4As shown in the figure, a valve for a quick-installation pipeline assembly includes a pipeline 1. A quick-installation joint cylinder 2 is provided at the top of the pipeline 1. A valve pipe fitting 3 is provided above the quick-installation joint cylinder 2. A nozzle 4 is provided above the valve pipe fitting 3. An externally threaded connecting pipe 41 is provided at one end of the nozzle 4 close to the valve pipe fitting 3. The externally threaded connecting pipe 41 is inserted into the inner top of the valve pipe fitting 3 and is threadedly connected thereto. A bottom connector 32 is provided at one end of the valve pipe fitting 3 away from the nozzle 4. A pressure ring 33 is provided at the bottom of the bottom connector 32. A valve switch 31 is provided at the external part of the valve pipe fitting 3 between the nozzle 4 and the bottom connector 32. An upper groove 211 is drilled at the top of the quick-installation joint cylinder 2. A lower groove 212 is drilled at the inner bottom of the quick-installation joint cylinder 2 where the upper groove 211 is located. A screw groove 213 is drilled at the inner wall of one end of the upper groove 211 away from the lower groove 212. Two half cylinders 22 are inserted into the inner bottom of the upper groove 211 close to the lower groove 212. Upper edge plates 23 are provided at the tops of the half cylinders 22. Ring grooves 231 are drilled at the tops of the upper edge plates 23. A sealing ring 232 is embedded inside between the ring grooves 231. A nut 5 is sleeved on the external part of the pipeline 1. External screw teeth 6 are provided on the outer walls at the bottoms of the half cylinders 22 and on the outer wall of the bottom connector 32.

[0022] In this embodiment, both the bottom connector 32 and the pressure ring 33 are inserted into the inner top of the upper groove 211, and the bottom connector 32 is threadedly connected to the screw groove 213 through the external screw teeth 6 on its outer wall.

[0023] In this embodiment, the bottom of the pressure ring 33 is in contact with the top of the sealing ring 232 to ensure the sealing performance of the fit between the pressure ring 33 and the upper edge plate 23.

[0024] In this embodiment, the half cylinders 22 are respectively communicated with the quick-installation joint cylinder 2 through the lower grooves 212, and the external screw teeth 6 on the outer walls of the half cylinders 22 are all located outside the bottom of the quick-installation joint cylinder 2. The nut 5 is sleeved on the external end of the half cylinder 22 passing through the lower groove 212, and the half cylinders 22 are both threadedly connected to the nut 5 through the external screw teeth 6. By rotating the nut 5 and threadedly connecting it at the external screw teeth 6 after the half cylinder 22 passes through the lower groove 212, the bottom connector 32 and the nut 5 squeeze and clamp the quick-installation joint cylinder 2 and the upper edge plate 23, further increasing the connection stability.

[0025] In this embodiment, sealing tapes are wound on the outer walls of the half cylinders 22 and the bottom connector 32 at the positions of the external screw teeth 6 and on the outer wall of the externally threaded connecting pipe 41, which has the effects of preventing thread wear and corrosion at the connection points.

[0026] In this embodiment, the inner diameter size formed between the upper edge plates 23 matches the inner diameter size of the upper groove 211, avoiding the situation of shaking after the quick-installation joint cylinder 2 is connected to the half cylinders 22 and the bottom connector 32, and ensuring the connection stability.

At this time, lift the quick-connect fitting cylinder 2. After the half cylinder 22 is inserted into the upper groove 211, it passes through the lower groove 212. At this time, the external screw teeth 6 at its bottom pass through the lower groove 212, and the bottom of the upper edge plate 23 touches the inside of the upper groove 211. Subsequently, the bottom connector 32 is inserted into the upper groove 211 and threadedly connected to the screw groove 213 through the external screw teeth 6. After being screwed in deeply, the pressure ring 33 presses on the sealing ring 232 on the top of the upper edge plate 23 to ensure the sealing performance after connection. Then, rotate the nut 5 and threadedly connect it to the external screw teeth 6 after the half cylinder 22 passes through the lower groove 212, so that the bottom connector 32 and the nut 5 squeeze and clamp the quick-connect fitting cylinder 2 and the upper edge plate 23, further increasing the connection stability and sealing performance. Finally, threadedly connect the external thread connecting pipe 41 to the inner top of the valve fitting 3. This installation method can quickly complete the rapid assembly among the pipe 1, the valve fitting 3, and the nozzle 4 in a short time, ensuring that the nozzle 4 can be used quickly.
