Description

Technical Field

[0001] The utility model relates to the technical field of regulating valve equipment, in particular to a self-cleaning multi-stage pressure-reducing regulating valve. Background Art

[0002] At present, conventional multi-stage pressure reduction and noise reduction valves generally reduce pressure and noise by increasing the damping of the flow channel to reduce the energy of the fluid.

[0003] The application number is CN202322876932.X, which discloses a multi-stage pressure-reducing regulating valve, including a valve body, a valve seat, a valve core, a valve cover, a valve stem and a packing; a sleeve assembly, a balancing cylinder and a balancing sealing ring are arranged in the valve body, the sleeve assembly is arranged on the valve seat, and the balancing cylinder is arranged on the sleeve assembly; the sleeve assembly includes a top ring, an adjusting ring and a bottom ring; one or more regulating channels are opened on the upper surface or the lower surface of the adjusting ring, and the regulating channel includes a regulating channel inlet section, a damping channel section and a regulating channel outlet section, and the regulating channel inlet section is connected to the regulating channel outlet section through a first-level damping channel section or a multi-stage damping channel section connected end to end; the damping channel section includes a first and a second damping channel, and the outlet end of the first damping channel merges with the outlet end of the second damping channel and the convergence angle is greater than or equal to 90°. The valve of the utility model has better effects in reducing pressure, speed and noise, and has better adjustment accuracy and stability.

[0004] A multi-stage pressure-reducing regulating valve disclosed in the above document has the following defects: during use of the regulating valve, it is necessary to connect the port of the valve body to a pipeline for liquid circulation, and to achieve the functions of pressure reduction, speed reduction and noise reduction through a damping flow channel. When the connection between the connecting pipe and the port of the valve body is affected by the air pressure in the valve, it is necessary to set a corresponding reinforcement component to make the liquid circulation more stable and prevent liquid leakage.

[0005] It can be seen from this that the existing multi-stage pressure-reducing regulating valve does not have the function of ensuring stable flow of liquid, and it is necessary to improve the existing deficiencies and provide a function that can reinforce the port and the pipe connection end to ensure stable flow of liquid.

Through the setting of the stop valve block 104, the flow of the liquid at the input end 102 is controlled. The regulating valve block 105 regulates the flow rate of the liquid at the output end 103. The port of the output end 103 is provided with an inclined surface sleeve block 108. Since the sealing ring 201 is made of deformable rubber material, the sealing ring 201 is sleeved forward and deformed along the narrow diameter of the inclined surface sleeve block 108. The inclined surface sleeve block 108 facilitates the forward movement of the sealing ring 201. Finally, the sealing ring 201 is fixed on the outer wall of the inclined surface sleeve block 108.
