Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valves, specifically a piston flow regulating and pressure regulating valve. Background Technology

[0002] A pressure regulating valve is a device used to regulate the pressure of fluids (gas or liquid). It mainly consists of a valve body, a valve core, a spring, and other components. When in operation, the size of the fluid passage is controlled by changing the position of the valve core, thereby regulating the pressure. For example, in a gas pipeline, when the inlet pressure is too high, the pressure regulating valve can reduce it to the set value.

[0003] A piston flow and pressure regulating valve is a type of valve used to control the flow rate and pressure of fluids (liquid or gas). Its core component is the piston. The flow rate is adjusted by changing the cross-sectional area of ​​the fluid passage through the movement of the piston within the valve body. In terms of pressure regulation, the pressure difference on both sides of the piston interacts with an internal elastic element (such as a spring) to automatically balance the pressure.

[0004] Existing piston flow regulating valves have the following problems: they do not have the function of filtering and handling impurities. When impurities are present, the valve is usually closed, the pipeline is disassembled, and tools are used to remove the blockage. This results in a high workload and consumes labor costs. To address the above problems, a piston flow regulating valve is proposed. Utility Model Content

[0036] The working principle is as follows: The entire device is installed via the first flange 1 and the second flange 8. When the brake motor 6 is turned on, its output rotates, driving the rotating rod 30 and gear 29 to rotate. This causes the rack 32 to slide along the second slide groove 31, which in turn causes the plug 27 and the leaking ring 26 to slide along the inner wall of the first slide groove 28. When the plug 27 disengages from the connecting pipe 9, the hole in the leaking ring 26 is pulled into the valve body 10, allowing water to flow out through the hole in the leaking ring 26. Returning all components to their original positions stops the water flow. When there are impurities in the water, they are intercepted by the filter screen 17. Heavier impurities settle to the bottom of the filter screen 17, while lighter impurities adhere to it. Rotating the cover 12 will drive the first rotating rod 19 and scraper 20 to rotate. The special inclined structure of the scraper 20 can send impurities to the bottom of the filter screen 17, and the upper end of the filter screen 17 can continue to ensure the smooth flow of water. A huge vibration will be generated at the moment of shutdown, or vibration will also be generated when other large machines in the factory are working for a long time. At this time, the mounting plate 7 presses down on the damping spring damper 5 to reduce vibration for the first time. At the same time, the rotating plate 24 rotates along the second ring 25 and the first ring 23, which will cause the first ring 23 to pull the damper 21, thus reducing vibration again. Through the damping spring damper 5 and the damper 21, the vibration can be quickly relieved.
