Description

Technical Field

[0001] This application relates to the field of valve pipe technology, and in particular to a valve pipe fitting. Background Technology

[0002] In fluid transport systems, valves and pipe fittings are key components for connecting pipelines, controlling on / off states, and regulating flow. Their main function is to effectively connect different pipe sections, while controlling the flow and shut-off of fluids through built-in valve structures. They are widely used in many scenarios such as industrial production, building water supply and drainage, HVAC, and mechanical equipment cooling systems.

[0003] Traditional valve pipe fittings typically employ a straight-line structure, meaning the inlet and outlet are on the same straight line, with fluid flowing in a straight direction. This structure works well in scenarios with ample space and a straight fluid flow direction. However, it is unsuitable for scenarios with limited space where water needs to flow from bottom to top. For example, in some small equipment, due to the compact layout of components, the reserved space for pipe installation is very limited. If it is necessary to guide water from the lower source to the upper liquid-requiring component, the straight-line valve pipe fitting will occupy too much vertical or horizontal space due to its own structure, making it impossible to coordinate with the surrounding components. Utility Model Content

[0004] This application provides a space-saving valve fitting.

[0005] The valve pipe fitting provided in this application adopts the following technical solution:

[0006] A valve fitting includes a valve body having a vertical channel and a horizontal channel communicating with each other. The horizontal channel is located above the vertical channel, and a liquid outlet is formed on one side of the horizontal channel. A liquid outlet thread is formed inside the liquid outlet. The vertical channel is a variable diameter channel, with its larger diameter section located below its smaller diameter section and forming a liquid inlet. A liquid inlet thread is formed inside the liquid inlet. A check valve component is provided in the smaller diameter section of the vertical channel. The check valve component includes a spring assembly and a valve core. The spring assembly is connected to the valve body and located in the smaller diameter section of the vertical channel. The valve core is fixed to the upper end of the spring assembly and includes a concave bottom. The valve core is used to open or close the vertical channel by moving vertically through the spring assembly.

[0007] Preferably, the spring assembly includes two springs connected to the bottom of the valve core; two support columns are provided on the valve body, the two support columns are located below the small diameter section of the vertical channel, and the two springs pass through the small diameter section of the vertical channel and are respectively connected to the two support columns.

[0008] Preferably, the valve core includes a core body and two sealing posts disposed on both sides of the core body; the small-diameter section of the vertical channel includes two grooves that match the two sealing posts; the two springs are respectively connected to the bottom of the two sealing posts and respectively pass through the two grooves.

[0009] Preferably, it also includes a conversion connector, wherein the diameter of the inlet of the conversion connector is smaller or larger than the diameter of its outlet, and is provided with threads, and the outlet of the conversion connector is threadedly connected to the inlet thread of the valve body.

[0010] Preferably, the top of the adapter is provided with a sealing gasket, which is used to abut against the top of the large-diameter section of the vertical channel.

[0011] Preferably, the valve body is provided with a buffer pad, which is located directly above the valve core and is used to provide cushioning when in contact with the valve core.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. This application improves space utilization through the design of a right-angle structure between the vertical and horizontal channels, making it suitable for compact environments. A valve core is elastically connected within the vertical channel, allowing it to move upwards under liquid impact to open the vertical channel, connecting it to the horizontal channel and allowing liquid to enter. After the liquid flow stops, the valve core moves downwards under elastic force to close the vertical channel, adapting to the bottom-to-top liquid flow path and achieving dynamic sealing of the valve core. The structure is simple, requires no manual operation, and saves costs.

[0014] 2. By using a conversion adapter connected to the inlet thread, the valve body can be flexibly adjusted to match the size of the external pipeline for connection.

[0015] 3. By setting sealing posts on both sides of the core, and providing grooves for the vertical channel corresponding to the sealing posts, the sealing performance between the valve core and the vertical channel is enhanced. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a valve pipe fitting, such as Figures 1 to 6 As shown, the valve includes a valve body 1, which is made of stainless steel. The valve body 1 has interconnected vertical and horizontal channels. The horizontal channel is located above the vertical channel. One side of the horizontal channel has an outlet with an outlet thread 11. The other side of the horizontal channel is closed. The vertical channel is located below the middle of the horizontal channel and is a variable diameter channel, with its larger diameter section below the smaller diameter section. An inlet is formed in the vertical channel with an inlet thread 12. The valve body 1 can be connected to an external pipe via the inlet thread 12. The inlet can also be detachably connected to a conversion connector 3. The inlet diameter of the adapter 3 is smaller or larger than its outlet diameter and is threaded. The outlet thread 11 of the adapter 3 is connected to the inlet thread 12 of the valve body 1. A sealing gasket 4 is provided on the top of the adapter 3. The sealing gasket 4 is used to abut against the top of the large-diameter section of the vertical channel to improve the sealing performance between the adapter 3 and the valve body 1. The thread of the adapter 3 is compatible with the external pipeline. By adding the adapter 3, when the inlet size of the valve body 1 is not compatible with the external pipeline, the adapter 3 can be more flexibly adapted to the size of the external pipeline and connected to the external pipeline without replacing the valve body 1, thus improving the installation efficiency.

[0025] like Figure 2 , Figure 5 and Figure 6As shown, a check valve component 2 is installed in the small-diameter section of the vertical channel. The check valve component 2 includes a valve core 22 and a spring 211 assembly 21. The valve core 22 includes a core body 222 and two sealing posts 223 disposed on both sides of the core body 222. The core body 222 is a cylindrical core body 222, and the bottom of the core body 222 is a concave bottom 221. The two sealing posts 223 are distributed at a 180° interval on both sides of the cylindrical core body 222. The sealing posts 223 are made of rubber. The spring 211 assembly 21 includes two springs 211. The upper ends of the springs 211 are respectively located at the bottom of the two sealing pillars 223. The small diameter section of the vertical channel includes two grooves 14 that match the two sealing pillars 223. The cross section of the small diameter section matches the cross section of the valve core 22. Two support pillars 13 are provided below the two sealing pillars 223. The two springs 211 are respectively located on the two support pillars 13 and are respectively inserted into the two grooves 14. The valve core 22 moves along the axial direction of the vertical channel by the elasticity of the springs 211, that is, moves vertically, to open or close the vertical channel.

[0026] like Figure 2 As shown, a buffer pad 5 is provided at the top inside the valve body 1. The buffer pad 5 is located directly above the valve core 22 and is used to provide cushioning when in contact with the valve core 22.

[0027] In practical use, the valve pipe fitting of this application bridges two external pipes through the inlet and outlet of the valve body 1. It should be noted that since the adapter 3 is threadedly connected to the inlet, the adapter 3 can be removed from the valve body 1 as needed to connect the inlet to the external pipe. When the size of the inlet does not match the external pipe, the adapter 3 can be installed to connect the adapter 3 to the external pipe. Liquid from the inlet or adapter 3 impacts the valve body 1. Through the concave bottom 221 of the valve body 1, the impact force received by the valve body 1 is concentrated in the middle, enhancing the impact effect. The valve body 1 moves upward under force until it moves out of the vertical channel, connecting the vertical channel and the horizontal channel. If the impact force of the water flow is too large, the valve core 22 will push against the buffer pad 5. Under the action of the buffer pad 5, the valve core 22 is prevented from being damaged. After the water flow stops, the valve core 22 moves downward under the action of elastic force to be embedded in the vertical channel to close the vertical channel. When the sealing column 223 is embedded in the vertical channel, the sealing performance of the vertical channel in the closed state is stronger. It should be noted that the liquid transported by the external pipeline bridged by the valve pipe joint of this application has sufficient impact force to push the valve core 22 out of the vertical channel.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
