Description

Technical Field

[0001] The utility model relates to the technical field of distribution valves, in particular to a distribution valve with a gap adjustment structure. Background Art

[0002] In the fluid distribution system, the distribution valve plays a vital role. It is not only a key component for controlling the direction and flow of fluid, but also directly related to the stability and efficiency of the entire system. The precise adjustment capability of the distribution valve is of irreplaceable importance in ensuring the on-demand distribution of fluid, avoiding resource waste and ensuring the safe operation of the system.

[0003] Traditional distribution valves have limitations in providing precise flow regulation and can usually only achieve basic fluid switching functions. Their performance is particularly insufficient in application scenarios that require frequent adjustment or high-precision control. In addition, some distribution valves often require users to perform complex operations during the adjustment process, such as disassembling the valve and adjusting internal components, which undoubtedly increases the complexity and inconvenience of operation.

[0004] Therefore, in view of the fact that the above-mentioned traditional distribution valve can only realize the basic fluid switching function but does not have the fluid flow regulation function, a distribution valve with a gap adjustment structure can be designed. Through the rotating structure and observation window, the user can easily adjust the position of the valve core in the No. 2 fluid channel, and then accurately control the gap width when the fluid flows through, so as to achieve the purpose of flexible flow regulation. Utility Model Content

[0005] In order to overcome the problem that traditional distribution valves can only realize basic fluid switching functions but do not have fluid flow regulation functions.

[0006] The technical solution of the utility model is: a distribution valve with a gap adjustment structure, comprising a shell, a water inlet pipe installed at the left end of the shell and a distribution pipe installed at the side end of the shell, a No. 1 fluid channel is opened in the shell and the No. 1 fluid channel is connected to the pipe mouth of the water inlet pipe, the water outlet of the No. 1 fluid channel is provided with a No. 2 fluid channel for adjusting the gap, a No. 3 fluid channel is opened in the shell and the water outlet of the No. 3 fluid channel is connected to the distribution pipe, the water inlet of the No. 3 fluid channel is connected to the No. 2 fluid channel, a rotating structure is installed at the upper end of the shell and the rotating structure is located in the No. 2 fluid channel, a valve core is installed at the lower end of the rotating structure, a sealing ring adapted to the water inlet of the No. 2 fluid channel is installed on the surface of the valve core, and the valve core is movably connected in the No. 2 fluid channel.

[0007] Preferably, the No. 2 fluid channel is composed of a vertical portion and a tapered portion, and the tapered portion is located below the vertical portion. The valve core adjusts the water outlet gap by vertically moving in the tapered portion.

[0008] Preferably, the rotating structure includes a screw, a knob and a sealing ring; the upper end of the shell is threadedly connected to the screw, the contact surface between the screw and the shell is provided with a sealing ring, and one end of the screw is fixedly connected to the knob.

[0009] Preferably, the side wall of the knob is provided with anti-slip grooves, and the rotation of the knob drives the screw to move vertically.

[0010] Preferably, an observation window is installed at the front end of the shell, through which the position of the valve core in the second fluid channel can be observed.

[0011] Preferably, the valve core is a columnar structure and the cross section of the valve core is adapted to the water inlet of the second fluid channel.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared to traditional distribution valves, this solution uses a rotating structure that allows users to easily adjust the position of the valve core in the No. 2 fluid channel by rotating it, thereby precisely controlling the gap width as the fluid flows through it, achieving the purpose of flexible flow adjustment. In addition, the equipped observation window function allows users to intuitively view the specific position of the valve core in the No. 2 fluid channel without disassembly, which significantly improves the convenience and accuracy of operation.

[0014] 2. The inner wall of the tapered portion gradually shrinks to form a gradually smaller space. When the valve core moves vertically in the tapered portion, the gap between the valve core and the tapered portion will change, thereby changing the flow rate of the fluid.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 5The utility model provides an embodiment: a distribution valve with a gap adjustment structure, comprising a shell 1, a water inlet pipe 2 installed at the left end of the shell 1 and a distribution pipe 3 installed at the side end of the shell 1, a No. 1 fluid channel 4 is opened in the shell 1 and the No. 1 fluid channel 4 is connected to the pipe mouth of the water inlet pipe 2, the water outlet of the No. 1 fluid channel 4 is provided with a No. 2 fluid channel 5 for adjusting the gap, a No. 3 fluid channel 6 is opened in the shell 1 and the water outlet of the No. 3 fluid channel 6 is connected to the distribution pipe 3, the water inlet of the No. 3 fluid channel 6 is connected to the No. 2 fluid channel 5, a rotating structure is installed at the upper end of the shell 1 and the rotating structure is located In the No. 2 fluid channel 5, a valve core 7 is installed at the lower end of the rotating structure, and a sealing ring 8 adapted to the water inlet of the No. 2 fluid channel 5 is installed on the surface of the valve core 7. The valve core 7 is movably connected to the No. 2 fluid channel 5. The shell 1 is the main structure of the entire distribution valve, which wraps and protects the internal fluid channel and adjustment structure. The water inlet pipe 2 is the input end of the distribution valve, which is used to introduce the fluid into the distribution valve and is connected to the No. 1 fluid channel 4 inside the shell 1. The distribution pipe 3 is the output end of the distribution valve, which is used to transport the regulated fluid to the required place and is connected to the No. 3 fluid channel 6 inside the shell 1. The distribution pipe 3 is connected to the No. 1 fluid channel 6 inside the shell 1. The number is designed according to actual needs to meet the needs of different fluid distribution. The No. 1 fluid channel 4 is one of the main fluid channels inside the distribution valve. It connects the water inlet pipe 2 and the No. 2 fluid channel 5. The water outlet of the No. 1 fluid channel 4 is connected to the water inlet of the No. 2 fluid channel 5 to form a complete fluid path. The No. 2 fluid channel 5 is the gap adjustment structure inside the distribution valve. The water inlet of the No. 2 fluid channel 5 adopts a conical design so that the fluid can be regulated by the valve core 7 when passing through, thereby changing the flow rate of the fluid, thereby realizing the adjustment function. The No. 3 fluid channel 6 connects the No. 2 fluid channel 5 and the distribution valve. Tube 3, through the No. 3 fluid channel 6, the regulated fluid is transported to where it is needed. The design of the rotating structure allows the user to change the position of the valve core 7 by rotating it, thereby adjusting the gap size in the No. 2 fluid channel 5. It is also equipped with a sealing ring 8 to prevent leakage. The valve core 7 is the core regulating mechanism inside the distribution valve. The surface of the valve core 7 is installed with a sealing ring 8 that is adapted to the water inlet of the No. 2 fluid channel 5 to ensure that the fluid will not leak when the valve core 7 is closed. By changing the position of the valve core 7 in the No. 2 fluid channel 5, the user can adjust the gap size when the fluid passes through, thereby changing the flow rate of the fluid.

[0023] See also Figure 5In this embodiment, the second fluid channel 5 is composed of a vertical portion 9 and a tapered portion 10, and the tapered portion 10 is located at the lower side of the vertical portion 9. The valve core 7 adjusts the water outlet gap by vertically moving in the tapered portion 10. The vertical portion 9 is the upper half of the second fluid channel 5. The shape of the vertical portion 9 is cylindrical or similar. The lower end of the vertical portion 9 is connected to the tapered portion 10. The tapered portion 10 is the lower half of the second fluid channel 5. It is connected to the water outlet of the first fluid channel 4. The shape of the tapered portion 10 is conical. Or a similar shape, its inner wall gradually shrinks to form a gradually smaller space. The design of the tapered portion 10 allows the fluid to be regulated by the valve core 7 when passing through. When the valve core 7 moves vertically in the tapered portion 10, the gap between the valve core 7 and the tapered portion 10 will change, thereby changing the flow rate of the fluid. Specifically, when the valve core 7 moves upward, the water outlet gap gradually increases, and the fluid flow or pressure increases accordingly. When the valve core 7 moves downward, the water outlet gap gradually decreases, and the fluid flow or pressure decreases accordingly.

[0024] See also Figure 4 In this embodiment, the rotating structure includes a screw 11, a knob 12 and a sealing ring 13; the upper end of the shell 1 is threadedly connected to the screw 11, and a sealing ring 13 is provided on the contact surface between the screw 11 and the shell 1. One end of the screw 11 is fixedly connected to the knob 12, and the side wall of the knob 12 is provided with an anti-slip groove 14. The rotation of the knob 12 drives the screw 11 to move vertically. The knob 12 is an operating component of the rotating structure. It directly contacts the user's hand, allowing the user to drive the screw 11 to move vertically by rotating the operation, thereby driving the valve core 7 to move vertically. The material of the knob 12 is selected from plastic, metal or alloy, etc., which is lightweight, strong and easy to process, to ensure that the user can easily hold and rotate it. The sealing ring 13 is used to prevent the fluid from leaking from the gap between the screw 11 and the shell 1. The material of the sealing ring 13 is usually selected from rubber or silicone materials with good elasticity and corrosion resistance. Its shape and size match the contact surface of the screw 11 and the shell 1 to ensure that a tight sealing effect can be maintained.

[0025] See also Figure 1 and Figure 5 In this embodiment, an observation window 15 is installed at the front end of the shell 1, through which the position of the valve core 7 in the No. 2 fluid channel 5 can be observed. The valve core 7 is a columnar structure and the cross-section of the valve core 7 is adapted to the water inlet of the No. 2 fluid channel 5. The observation window 15 is made of a transparent and high-pressure resistant material, such as tempered glass, which allows the user to directly observe the position of the valve core 7 in the No. 2 fluid channel 5 without disassembling the shell 1. This design improves the convenience of operation. The valve core 7 is designed to be a columnar structure, and its cross-section is fully adapted to the water inlet of the No. 2 fluid channel 5. This design ensures that the valve core 7 can tightly seal the water inlet of the No. 1 fluid channel 4 when it is closed to prevent fluid leakage.

[0026] During operation, the water inlet pipe 2 and the distribution pipe 3 are first connected to the external pipeline. Then, the fluid flows into the No. 1 fluid channel 4 through the water inlet pipe 2. Since the valve core 7 is in the closed state at this time, the fluid cannot enter the No. 2 fluid channel 5.

[0027] Next, rotate the knob 12, and the screw 11 moves vertically by the transmission principle of the thread, driving the valve core 7 to move vertically synchronously. At this time, the fluid can flow into the second fluid channel 5 through the gap between the valve core 7 and the tapered portion 10. At the same time, the specific position of the valve core 7 can be observed through the observation window 15, so as to more accurately adjust the size of the gap.

[0028] After entering the No. 2 fluid channel 5 , the fluid will continue to flow into the No. 3 fluid channel 6 through the water inlet of the No. 3 fluid channel 6 , and finally enter the distribution pipe 3 , thereby achieving the fluid distribution effect.

[0029] Through the above steps, compared with the traditional distribution valve, this solution uses a rotating structure to enable the user to easily adjust the position of the valve core 7 in the No. 2 fluid channel 5 through a rotating action, and then accurately control the gap width when the fluid flows through, so as to achieve the purpose of flexibly adjusting the flow rate. In addition, the equipped observation window 15 function allows the user to intuitively view the specific position of the valve core 7 in the No. 2 fluid channel 5 without disassembly. This feature significantly improves the convenience and accuracy of operation, and solves the problem that the traditional distribution valve can only realize the basic fluid switching function but does not have the fluid flow regulation function.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
