Description

Technical Field

[0001] This application relates to the field of drain valves, and more particularly to a drain valve. Background Technology

[0002] Currently, drain valves are devices used to drain water or harmful liquids and are widely used in many fields. The following will provide a detailed introduction from aspects such as basic information, common types and characteristics, application scenarios, and technical parameters. Drain valves are suitable for draining water or harmful liquids from compressed air storage tanks or other gas pressure vessels. They are mainly composed of valve body, valve cover, valve core, spring, adjusting bolt, drain hole, and valve body through hole, etc. They are characterized by simple structure, easy manufacturing, small size, and convenient use. They can completely drain water or other harmful liquids and can replace the lower plug of the compressor air receiver and the drain stop valve at the bottom of the air receiver, ensuring gas quality and preventing corrosion of pneumatic tools and pipeline components.

[0003] When existing drain valves are to be operated using non-manual control methods, solenoid valves are usually used. Solenoid valves are a type of electric valve that uses the magnetic field generated by an electromagnetic coil to pull the valve core, thereby changing the opening and closing of the valve body. When the coil is de-energized, the valve core returns to its original position due to the pressure of the spring. Solenoid valves are usually more expensive, which can lead to higher operating costs when drain valves are used extensively in normal circumstances. Utility Model Content

A first connecting ring 2 is fixed through the middle of the other side of the valve body 1. A miniature hydraulic telescopic rod 3 is fixed inside the first connecting ring 2. The miniature hydraulic telescopic rod 33 is fixed to the valve body 1 through the first connecting ring 2. A connecting rod 32 is fixed to the power output end of the miniature hydraulic telescopic rod 3. A baffle 33 is fixed to one end of the connecting rod 32. The baffle 33 and the connecting rod are both made of waterproof material. The water inlet pipe 6 and the drain pipe 7 are arranged vertically, so that when the baffle 33 blocks the water inlet pipe 6, water will not continue to flow out of the drain pipe 7. When the baffle 33 contracts, the water in the water inlet pipe 6 can be discharged from the drain pipe 7.

[0029] Reference Appendix Figure 1 and 2 The miniature hydraulic telescopic rod 3 has connecting holes 31 fixed through both ends of its outer wall. The connecting rod 32 is located on the inner wall of the valve body 1, and a sealing gasket 34 is fixed on the side of the baffle 33 near the water inlet pipe 6. By connecting the two connecting holes 31 to the external hydraulic device, the movement of the connecting rod 32 is controlled by the hydraulic device, thereby controlling the position of the baffle 33. The sealing gasket 34 is used to fill the gap between the baffle 33 and the water inlet pipe 6 to prevent water leakage during use.

[0030] Reference Appendix Figure 2 The length of the connecting rod 32 is matched with the width of the inner wall of the valve body 1, and the diameter of the baffle 33 is greater than the diameter of the inlet pipe 6, so that when the connecting rod 32 is extended to its maximum length, the baffle 33 can abut against one end of the inlet pipe 6, and the baffle 33 can completely cover one end of the inlet pipe 6.

[0031] Reference Appendix Figure 2 and 3 The valve body 1 has threaded connecting rings 8 fixed in the middle of both the front and rear sides. One of the threaded connecting rings 8 has a threaded sleeve 9 inside, and the threaded sleeve 9 has a threaded telescopic rod 10 inside. The threaded sleeve 9 is connected to the threaded connecting ring 8 through the threaded connection, so that when installing the valve body 1, the threaded sleeve 9 can be connected to the threaded connecting ring 8 at the bottom according to the position of the valve body 1 after installation.

[0032] Reference Appendix Figure 2The threaded telescopic rod 10 is rotatably connected to a limiting block 11 at one end. The limiting block 11 is U-shaped. A threaded rod 12 is threadedly connected through the middle of one side of the limiting block 11. A knob 13 is fixed at one end of the threaded rod 12, and a pressing block 14 is rotatably connected to the other end of the threaded rod 12. When using the limiting block 11 for installation, the position of the limiting block 11 is adjusted by rotating the threaded telescopic rod 10 inside the threaded sleeve rod 9. After adjustment, the limiting block 11 is connected to the external pipeline. By rotating the knob 13, the threaded rod 12 is rotated, so that the pressing block 14 and the limiting block 11 cooperate to fix it.

[0033] Reference Appendix Figure 2 The valve body 1 is fixed with connecting blocks 4 on all four sides of the top. One of the connecting blocks 4 is detachably connected to a support block 5 on one side. The support block 5 can be selected for installation according to the external installation environment. By connecting the support block 5 with the connecting block 4 and fixing the support block 5 to the outside, the valve body 1 is fixed.

[0034] Reference Appendix Figure 2 and 4 The inlet pipe 6 and the outlet pipe 7 are both fixed with connecting pipes 15. The outer wall of the connecting pipe 15 is provided with a clamp 16. After the valve body 1 is installed, the external connecting pipe 15 is inserted into the outer wall of the inlet pipe 6 and the outlet pipe 7, and then the clamp 16 is used to fix the connecting pipe 15 to complete the installation.

[0035] The implementation principle of a drain valve according to an embodiment of this application is as follows: First, the installation method is selected according to the external installation environment. Alternatively, the valve body 1 can be fixed by connecting the support block 5 to the connecting block 4 and then fixing the support block 5 to the external environment. Or, the threaded sleeve 9 can be connected to the threaded connecting ring 8 via a threaded connection. This allows the threaded sleeve 9 to be connected to the threaded connecting ring 8 at the bottom, depending on the position of the valve body 1 after installation. The position of the limiting block 11 is adjusted by rotating the threaded telescopic rod 10 inside the threaded sleeve 9. After adjustment, the limiting block 11 is connected to the external pipeline. Rotating the knob 13 drives the threaded rod 12 to rotate, causing the compression block 14 and... The limiting block 11 is used for fixation. Finally, the external connecting pipe 15 is inserted into the outer wall of the water inlet pipe 6 and the drain pipe 7. The connecting pipe 15 is then fixed with the clamp 16 to complete the installation. By connecting the two connecting holes 31 to the external hydraulic device, the movement of the connecting rod 32 is controlled by the hydraulic device, thereby controlling the position of the baffle 33. The sealing gasket 34 is used to fill the gap between the baffle 33 and the water inlet pipe 6 to prevent water leakage during use. When the connecting rod 32 is extended to its maximum length, the baffle 33 can abut against one end of the water inlet pipe 6. At the same time, the baffle 33 can completely cover one end of the water inlet pipe 6, and water will not continue to flow out of the drain pipe 7. When the baffle 33 retracts, the water in the water inlet pipe 6 can be discharged from the drain pipe 7.
