Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a self-operated pressure stabilizing and balancing valve. Background Technology

[0002] Pressure regulating valves, also known as self-regulating balancing valves, flow control valves, flow controllers, dynamic balancing valves, and flow balancing valves, are intuitive and simple flow regulation and control devices. In pipeline networks, flow regulating valves allow for direct flow setting according to design specifications. Under the action of water, the valve automatically eliminates flow deviations caused by residual head and pressure fluctuations in the pipeline, maintaining a constant set flow rate regardless of system pressure changes. These functions enable one-step flow regulation, transforming network adjustment into simple flow distribution and effectively resolving hydraulic imbalances in the pipeline network. Flow regulating valves are mainly used in centralized heating (cooling) water systems to distribute pipeline flow as needed, eliminate hydraulic imbalances in the water system, and solve problems of uneven heating and cooling.

[0003] For example, Chinese patent application number 201610240380.5 discloses a self-operated pressure stabilizing valve, which consists of an upper end cover, a pressure cap, an adjusting rod, a gasket, a valve, an upper valve body, a valve seat, a lower valve body, a diaphragm, a lower end cover, a locking cap, a pressure adjusting shaft, a spring, a spring seat, a valve stem, a baffle, a valve body gasket, and a sealing gasket. The adjusting rod passes through the central hole from the large end of the upper end cover, and the stud head is screwed into the corresponding thread. After the valve and valve stem are fixed together, the rod passes through the upper valve body, valve seat, valve body gasket, lower valve body, baffle, diaphragm, and is threadedly connected to the spring seat. The pressure adjusting shaft is screwed into the lower end cover, and a spring is installed at the cylindrical end of the pressure adjusting shaft. The lower end cover abuts against the diaphragm and fastens onto the lower valve body. A sealing gasket is placed between the upper end cover and the upper valve body, with the side planes aligned. Bolts are inserted into the assembly hole for tightening. A gasket is embedded at the output end of the adjusting rod on the upper end cover, and a pressure cap is screwed in. A locking cap is screwed into the threaded end of the pressure adjusting shaft. This invention is connected in series in each branch and adjusts itself around the set value to ensure the relative stability of flow and pressure at the working end.

[0004] However, this self-regulating pressure balancing valve still has some shortcomings in actual use. For example, it lacks the necessary filter components at the inlet end. Once impurities in the pipeline enter the valve, these substances will damage the valve seat and ball core, thereby reducing the service life of the balancing valve. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: including a main component 1, a filter liquid inlet component 2 is fixedly installed on one side of the main component 1, the main component 1 includes a valve body 101, and a valve core 102 is inserted into the top of the valve body 101;

[0022] The filtration and liquid inlet assembly 2 includes an inlet pipe 201. A second-order hexagonal nut 202 is fixedly installed at one end of the inlet pipe 201. An outer filter plate 203 is fixedly embedded inside the inlet pipe 201. A circular groove is formed inside the outer filter plate 203. An inner filter plate 204 is rotatably installed inside the circular groove. An arc-shaped toothed plate 205 is fixedly embedded on one side of the inner filter plate 204. An installation block 206 is fixedly installed on the outside of the inlet pipe 201. An installation groove 207 is formed inside the installation block 206. A gear 208 is rotatably installed on the side of the middle of the installation groove 207 near the inlet pipe 201. A threaded vertical rod 209 is rotatably installed on the other side of the installation groove 207. A lifting toothed plate 210 is threaded onto the rod of the threaded vertical rod 209. A servo motor 211 is fixedly installed on the top surface of the installation block 206. A debris collection pipe 212 is fixedly embedded at the bottom of the outside of the inlet pipe 201.

[0023] In this embodiment, a valve cover 103 is provided at the top of the valve core 102, and a liquid outlet pipe 104 is fixedly installed on one side of the valve body 101. A first-joint hexagonal nut 105 is fixedly installed at one end of the liquid outlet pipe 104. The balance valve can be conveniently installed in the pipeline path through the first-joint hexagonal nut 105 and the second-joint hexagonal nut 202.

[0024] Meanwhile, the lifting gear plate 210 is slidably installed in the mounting groove 207. Filter ports are provided on the surfaces of both the outer filter plate 203 and the inner filter plate 204. The liquid inlet pipe 201 is fixedly installed on the outer side of the valve body 101. The bottom end of the output shaft of the servo motor 211 is fixedly connected to the top end of the threaded vertical rod 209. The gear 208 is located between the arc-shaped gear plate 205 and the lifting gear plate 210. Both sides of the gear 208 are respectively meshed with the arc-shaped gear plate 205 and the lifting gear plate 210, allowing the servo motor 211 to be started. The servo motor 211 drives the threaded vertical rod. Rotation of 209 causes the threaded vertical rod 209 to move the lifting gear plate 210 up and down within the mounting slot 207. The movement of the lifting gear plate 210 causes the gear 208 to rotate, which in turn causes the arc-shaped gear plate 205 to move. The movement of the arc-shaped gear plate 205 causes the inner filter plate 204 to rotate within the outer filter plate 203. The rotation of the inner filter plate 204 changes the alignment of the filter openings on the inner filter plate 204 with the filter openings on the surface of the outer filter plate 203 from complete overlap to partial overlap and then to no overlap, thus allowing for easy adjustment of the filter opening diameter.

[0025] The top of the collection tube 212 is connected to the inside of the inlet tube 201. The bottom end of the collection tube 212 is threaded with a threaded cap 213. By unscrewing the threaded cap 213 and adjusting the diameter of the filter port to be completely closed, flushing water can be injected. The water will flush out the filtered impurities from the collection tube 212, thereby conveniently and quickly discharging the impurities from the inlet tube 201 and reducing the difficulty of cleaning the balance valve.

[0026] In use, liquid is injected from one end of the inlet pipe 201. After entering, it first passes through the outer filter plate 203 and the inner filter plate 204, which filter the liquid entering the valve, effectively preventing impurities from entering the valve and damaging the valve seat and ball core, thus avoiding a reduction in the service life of the balancing valve. When this balancing valve is used in different environments, the filtration requirements will vary. Therefore, when it is necessary to change the filtration effect, the servo motor 211 can be activated. The servo motor 211 drives the threaded vertical rod 209 to rotate. The rotation of the threaded vertical rod 209 drives the lifting gear plate 210 to move up and down within the mounting groove 207. The movement of the lifting gear plate 210 drives the gear 208 to rotate. The arc-shaped toothed plate 205 can be moved, and the movement of the arc-shaped toothed plate 205 can cause the inner filter plate 204 to rotate inside the outer filter plate 203. The rotation of the inner filter plate 204 can change the filter port on the inner filter plate 204 from completely overlapping to partially overlapping and completely non-overlapping with the filter port on the surface of the outer filter plate 203, thereby making it easy to change the size of the filter port diameter. At the same time, after filtering for a period of time, in order to prevent impurities from accumulating at the inlet of the liquid inlet pipe 201, the threaded cap 213 can be unscrewed, and then the diameter of the filter port can be adjusted to be completely closed. At this time, flushing water is injected, and the water will flush out the filtered impurities from the impurity collection pipe 212, thereby conveniently and quickly discharging impurities from the liquid inlet pipe 201 and reducing the cleaning difficulty of the balance valve.

[0027] In summary, this self-regulating pressure balancing valve, through the external filter plate 203 and the internal filter plate 204, can filter the liquid entering the valve, effectively preventing impurities from entering the valve and damaging the valve seat and ball core, thus avoiding a reduction in the service life of the balancing valve. Furthermore, the internal filter plate 204 can be easily rotated to change the alignment of its filter openings with those on the surface of the external filter plate 203, from complete overlap to partial overlap or complete non-overlap, thereby easily changing the size of the filter openings to adapt to different working environments and enhancing its practicality.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
