Description

Technical Field

[0001] This utility model belongs to the field of valve equipment, and specifically relates to a freeze-resistant and anti-clogging throttling valve assembly. Background Technology

[0002] Throttling valve assemblies are fluid control devices for throttling, regulating, and guiding media flow. Existing throttling valve assemblies are prone to problems such as flow channel blockage, operational jamming, and reduced sealing performance in low-temperature environments or when conveying media containing easily crystallizing or particulate matter. These problems stem from the temperature drop effect caused by sudden pressure changes during throttling, which may promote the formation of hydrates or crystals in the media. Simultaneously, conventional flow channel designs easily lead to impurity retention, and conventional materials and sealing structures tend to lose toughness and elasticity at low temperatures. Conventional solutions often involve replacing sealing components with those marked with low-temperature resistance ratings or increasing the frequency of manual flushing and drainage; in some scenarios, sealing components are replaced periodically. However, these methods have significant drawbacks. Manual maintenance not only increases labor costs but also makes it difficult to guarantee the timeliness of flushing and drainage, potentially leading to downtime. Frequent replacement of sealing components affects system stability and fails to fundamentally alleviate the impact of low temperatures on the valve body structure and the problem of media crystallization and deposition, making it difficult to meet the long-term stable operation requirements under complex conditions. Therefore, a new structure is needed to solve the aforementioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a freeze-resistant and anti-clogging throttling valve assembly to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a freeze-resistant and anti-clogging throttling valve assembly, comprising: an antifreeze component and a valve assembly, wherein the valve assembly is installed inside the antifreeze component, the antifreeze component includes a housing for freeze protection, and a cover plate for sealing is respectively installed on the upper and lower surfaces of the housing, the valve assembly includes a valve body, an adjusting component for adjustment is installed on the upper surface of the valve body through a connecting seat, an outlet pipe and an inlet pipe for water outlet and water inlet are installed on the outer surface of the valve body, and a flushing pipe for anti-clogging is installed on the outer surface of the valve body.

[0005] In a preferred embodiment, the cross-section of the outer shell is U-shaped, and both the upper and lower surfaces of the outer shell are designed with openings. The inner wall of the outer shell is provided with an insulation board for heat preservation and a heat insulation board for frost protection. A sealing ring is glued to the openings on both the upper and lower surfaces of the outer shell, and a cover plate is bolted to the openings on both the upper and lower surfaces of the outer shell.

[0006] In a preferred embodiment, a circular through hole 1 is provided at the center of the surface of the cover plate. The diameter of the circular through hole 1 on the upper surface of the cover plate is smaller than the diameter of the circular through hole 1 on the lower surface of the cover plate. A circular through hole 2 is provided on both the front and rear surfaces of the outer shell. A sealing ring is provided on the inner wall of both the circular through hole 1 and the circular through hole 2. In use, the outer shell provides stable protection for the internal valve assembly. Together with the insulation board and the heat insulation board, it forms a double heat insulation structure, which can effectively block the conduction of low temperature from the outside and prevent the valve assembly from failing due to low temperature brittleness or freezing of the medium.

[0007] In a preferred embodiment, an outlet pipe for water discharge is installed on the lower surface of the valve body, and an inlet pipe for water intake is installed on the front surface of the valve body. The inlet pipe and the outlet pipe have the same structure. A flushing hole for rinsing is opened on the side surface of the valve body away from the inlet pipe. A flushing pipe is installed at an angle on the front surface of the flushing hole. During use, the flushing pipe on the outside of the valve body can promptly introduce clean medium for rinsing when particle deposition or crystal blockage occurs in the flow channel. This effectively avoids a sudden drop in flow or valve failure caused by blockage, significantly reduces maintenance difficulty and downtime, and ensures long-term stable and efficient operation of the valve assembly under complex working conditions.

[0008] In a preferred embodiment, the end of the flushing pipe away from the valve body is connected to an external water supply device via a hose. The flushing pipe is connected to the interior of the valve body. The connecting seat includes a first sealing seat, a connecting column, and a second sealing seat. The connecting column is installed on the upper surface of the valve body via the first sealing seat.

[0009] In a preferred embodiment, a second sealing seat is threadedly installed at the end of the connecting column away from the first sealing seat. The adjusting component includes an adjusting knob, a connecting block, and an adjusting rod. The adjusting rod is threadedly installed through the upper surface of the connecting seat, and the connecting block is installed at the end of the adjusting rod away from the connecting seat.

[0010] In a preferred embodiment, an adjustment knob is provided at the end of the connecting block away from the adjustment rod. The adjustment rod is located inside the valve body, which is installed inside the outer casing. A water inlet pipe is provided inside the second circular through hole on the front surface of the outer casing, and a flushing pipe is provided inside the second circular through hole on the rear surface of the outer casing.

[0011] In a preferred embodiment, an adjusting rod is provided inside the circular through hole of the upper cover plate, and a water outlet pipe is provided inside the circular through hole of the lower cover plate.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1.

The antifreeze component includes a shell for antifreeze, and a heat insulation board and a heat insulation board are set inside the shell. A cover plate for sealing is installed on the upper and lower surfaces of the shell respectively. When in use, the shell provides stable protection for the internal valve component. Together with the heat insulation board and the heat insulation board, a double heat insulation structure is formed, which can effectively block the conduction of low temperature from the outside and prevent the valve component from failing due to low temperature brittleness and freezing of the medium.

[0013] 2. By setting up a valve assembly, the valve assembly includes a valve body. The upper surface of the valve body is equipped with an adjusting element for adjustment via a connecting seat. The outer surface of the valve body is equipped with an outlet pipe and an inlet pipe for water inlet and outlet.

[0025] 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.

[0026] Please see Figures 1 to 6 As the first embodiment of this utility model: a freeze-resistant and anti-clogging throttling valve assembly, comprising: an antifreeze component and a valve assembly, wherein the valve assembly is installed inside the antifreeze component, the antifreeze component includes a housing 100 for antifreeze, and a cover plate 120 for sealing is respectively installed on the upper and lower surfaces of the housing 100, the valve assembly includes a valve body 200, an adjusting component for adjustment is installed on the upper surface of the valve body 200 through a connecting seat, an outlet pipe 240 and an inlet pipe 250 for water outlet and water inlet are installed on the outer surface of the valve body 200, and a flushing pipe 400 for anti-clogging is installed on the outer surface of the valve body 200;

[0027] The cross-section of the outer shell 100 is U-shaped. Both the upper and lower surfaces of the outer shell 100 are designed with openings. The inner wall of the outer shell 100 is provided with an insulation board 130 for heat preservation and an insulation board 140 for frost protection. A sealing ring 110 is glued to the openings on the upper and lower surfaces of the outer shell 100. A cover plate 120 is bolted to the openings on the upper and lower surfaces of the outer shell 100 respectively.

[0028] A circular through hole 121 is provided at the center of the surface of the cover plate 120. The diameter of the circular through hole 121 on the surface of the upper cover plate 120 is smaller than the diameter of the circular through hole 121 on the surface of the lower cover plate 120. A circular through hole 101 is provided on the front and rear surfaces of the outer shell 100. A sealing ring 110 is provided on the inner wall of both the circular through hole 121 and the circular through hole 101.

[0029] A water outlet pipe 240 for water outlet is installed on the lower surface of the valve body 200, and a water inlet pipe 250 for water inlet is installed on the front surface of the valve body 200. The water inlet pipe 250 and the water outlet pipe 240 have the same structure. A flushing hole 201 for flushing is opened on the side surface of the valve body 200 away from the water inlet pipe 250. A flushing pipe 400 is installed on the front surface of the flushing hole 201 at an angle.

[0030] The end of the flushing pipe 400 away from the valve body 200 is connected to an external water supply device through a hose. The flushing pipe 400 is connected to the inside of the valve body 200. The connecting seat includes a sealing seat 1 210, a connecting column 220 and a sealing seat 230. The connecting column 220 is installed on the upper surface of the valve body 200 through the sealing seat 1 210.

[0031] The end of the connecting column 220 away from the sealing seat 210 is threadedly fitted with the sealing seat 230. The adjusting component includes an adjusting knob 310, a connecting block 300, and an adjusting rod 320. The adjusting rod 320 is threadedly fitted through the upper surface of the connecting seat. The connecting block 300 is installed at the end of the adjusting rod 320 away from the connecting seat.

[0032] In use, the user first opens the cover plates 120 on the upper and lower surfaces of the outer casing 100, exposing the openings on the upper and lower surfaces of the outer casing 100. The outlet pipe 240, inlet pipe 250, and flushing pipe 400 on the outer surface of the valve body 200 are all threadedly connected to the outer surface of the valve body 200. After preparing the outer casing 100, the valve body 200 is then installed inside the outer casing 100. Then, the above steps are reversed to install the cover plate 120 on the upper surface. When installing the cover plate 120 on the upper surface, the adjusting rod... 320 requires threaded removal of the connector. After the upper and lower surface cover plates 120 are installed, the user can then use the above steps to seal and thread the flushing pipe 400, outlet pipe 240, inlet pipe 250, and adjusting rod 320 to the valve body 200. At this time, the outer shell 100 will wrap and protect the valve body 200, providing stable protection for the internal valve components. Together with the insulation plate 130 and the heat insulation plate 140, a double heat insulation structure is formed, which can effectively block the conduction of low external temperature and prevent the valve components from failing due to low temperature brittleness or medium freezing.

[0033] Please see Figures 1 to 6 As a second embodiment of this utility model: based on the description in the above embodiments, further, an adjustment knob 310 is provided at the end of the connecting block 300 away from the adjustment rod 320, the adjustment rod 320 is provided inside the valve body 200, the valve body 200 is installed inside the outer shell 100, a water inlet pipe 250 is provided inside the circular through hole 2 101 on the front surface of the outer shell 100, and a flushing pipe 400 is provided inside the circular through hole 2 101 on the rear surface of the outer shell 100.

[0034] An adjusting rod 320 is installed inside the circular through hole 121 of the upper cover plate 120, and a water outlet pipe 240 is installed inside the circular through hole 121 of the lower cover plate 120.

[0035] When in use, after the valve assembly is installed inside the antifreeze assembly through the operation steps of the first embodiment, the valve assembly can be used (the specific structure and connection principle of the valve assembly are existing technologies and will not be described in detail here). After the valve assembly has been used for a period of time, sediment will be generated inside the valve assembly due to water quality and other reasons, and then deposited at the connection between the outlet pipe 240 and the inlet pipe 250. At this time, the user can start the external high-pressure water supply equipment, so that the equipment supplies water to the flushing pipe 400 through the hose. Then the valve on the outer surface of the flushing pipe 400 is opened, so that the flushing pipe 400 performs reverse flushing on the inside of the valve body 200, thereby flushing the sediment deposited inside the valve body 200. Then the valve body 200 is started to form a primary passage to discharge the internal sediment and impurities. Because the flushing pipe 400 on the outside of the valve body 200 can promptly introduce clean medium for flushing when particle deposition or crystal blockage occurs in the flow channel, it effectively avoids the sudden drop in flow or valve failure caused by blockage, greatly reduces maintenance difficulty and downtime, and ensures that the valve assembly operates stably and efficiently for a long time under complex working conditions.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
