Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, specifically a one-way valve with a guiding structure. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] According to Chinese Patent Publication No. CN222067690U, a one-way valve belongs to the field of valve technology and aims to solve the problem of existing one-way valves. During installation, the valve requires metal connectors at both ends, resulting in a heavy overall weight that is inconvenient for use. This one-way valve includes a valve body with a protruding seat. Cylindrical welding ends and connecting ends are respectively installed on both sides of the protruding seat. A connecting joint protrudes from the outer edge of the connecting end. The welding end and connecting end extend laterally to form a water guiding cavity. A connecting cavity is provided in the middle section of the water guiding cavity, and a one-way sealing component for auxiliary sealing is installed inside the water guiding cavity. The above technology uses welding ends to connect to the pipeline, which is inconvenient for installation and requires damage to the welding ends during disassembly, potentially damaging the pipeline and valve, causing inconvenience to workers and hindering valve disassembly and maintenance. Therefore, a one-way valve with a guiding structure is proposed to solve the above problems. Utility Model Content

[0019] like Figure 1-3As shown, this utility model provides a one-way valve with a guiding structure, including a valve body 1. A sealing block 5 is disposed inside the valve body 1. A connecting assembly 2 is disposed at the right end of the valve body 1. The connecting assembly 2 includes a first ring 21, a second ring 22, an annular sealing groove 23, and a sealing ring 24. The first ring 21 is connected to the right end of the valve body 1. The second ring 22 is disposed to the right of the first ring 21. The annular sealing groove 23 is formed to the right of the first ring 21. The sealing ring 24 is connected to the left of the second ring 22 and inserted into the annular sealing groove 23. A circular groove is formed on the outer wall of the sealing ring 24. A semi-circular strip 25 is attached to the outer wall of the first ring 21. A circular rod 26 is connected to the inner wall of the semi-circular strip 25 and passes through the first ring 21. The outer wall is inserted into the inside of the circular groove. The circular rod 26 is slidably connected to the circular ring 21. There are two semicircular bars 25, which surround the outer wall of the circular ring 21 in a circle. Multiple circular rods 26 are set on a single semicircular bar 25, and the circular rods 26 are of different lengths. With the circular groove of corresponding depth, the circular rods 26 can be vertically inserted into the circular groove when the semicircular bar 25 is in contact with the circular ring 21. The outer wall of the semicircular bar 25 is connected to an L-shaped plate 27, and the L-shaped plate 27 is threaded with a bolt 28. The bolt 28 is threadedly connected to the threaded groove on the left side of the circular ring 21. Three sets of L-shaped plates 27 and bolts 28 are set on a single semicircular bar 25 to improve the firmness after installation. When setting the bolt 28, the nut can be turned with one hand without the need for tools.

[0020] Specifically, by pre-welding the second ring 22 to the outlet of the pipeline, when installing the valve body 1, the sealing ring 24 is aligned with the annular sealing groove 23 and inserted, and then the semi-circular strip 25 is assembled so that the round rod 26 is inserted into the round groove to fix the sealing ring 24. Then the bolt 28 is tightened to complete the installation. When disassembling, the bolt 28 is loosened and the semi-circular strip 25 is removed to complete the disassembly, which brings convenience to the staff.

[0021] In this embodiment, the left end of the valve body 1 is threaded with a connecting end 3, and the outer wall of the connecting end 3 is connected with a connecting section 4. There are multiple connecting sections 4, which are linearly and equidistantly distributed. By fixing the connecting sections 4 to the outer wall of the connecting end 3, it is convenient to assemble the nylon tube later. The valve body 1 is internally connected with a cross plate 7, and the outer wall of the sealing block 5 is connected with a connecting rod 6. The connecting rod 6 passes through the cross plate 7 and is slidably connected to the cross plate 7. The right end of the connecting rod 6 is connected with a connecting plate 8, and the outer wall of the connecting rod 6 is fitted with a spring 9. The two ends of the spring 9 are respectively connected to the outer wall of the connecting plate 8 and the outer wall of the cross plate 7.

There are four guide rods 10, which are arranged in a circular array on the left side of the connecting plate 8.

[0022] Specifically, by threading the connecting end 3 to the valve body 1, it is easy to unscrew and maintain the inside of the valve body 1. By setting four guide rods 10, the sealing block 5 can be guided to prevent the sealing block 5 from shifting after long-term use and to improve the service life of the one-way valve. After the valve body 1 is installed, the liquid in the pipeline pushes the sealing block 5 to the right, which compresses the spring 9. The connecting end 3 is connected to the valve body 1, so that the liquid can flow in one direction. When the sealing block 5 is not pushed to the right, the spring 9 drives the sealing block 5 to reset and seal the connecting end 3.
