Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel pressure regulating valve. Background Art

[0002] The pressure regulating valve is an intuitive and simple flow control device. It is mainly used to stabilize the pressure in the fluid system and control the pressure change by automatically adjusting the cross-sectional area of ​​the fluid inlet and outlet to achieve the set pressure requirement.

[0003] A pressure regulating valve is disclosed in a Chinese utility model patent with publication number CN219388751U. The mounting ring is connected to the connecting ring by providing a mounting block and a mounting groove that are movably plugged in. During the connection process, the plug rod is plugged into the groove to lock the mounting block to enhance the connection stability. When disassembly is required, the movable block is moved outward to contract the spring, so that the plug rod is disengaged from the groove, the mounting block is pulled out of the mounting groove, and the filter screen in the connecting ring is replaced and cleaned. The placement groove is protected by a bellows to prevent external dust and humid air from entering the placement groove as much as possible. The latch is provided and pulled out after the mounting ring is disassembled, so that the filter screen is easy to disassemble and clean.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] Although the convenience of installing and disassembling the filter plate is ensured through the cooperation of various components, during the use of the pressure regulating valve, impurities in the fluid, such as sand, soil, leaves, etc., will accumulate on the surface of the filter plate under the filtering effect of the filter plate. Therefore, in order to ensure the smooth flow of the fluid and the filtering effect of the filter plate on the fluid, the filter plate needs to be disassembled and cleaned regularly. The time point for disassembly and cleaning of the existing filter plate is determined by the experience of the staff, which can easily cause the filter plate to be disassembled and cleaned too early or too late. If it is cleaned too early, the frequency of disassembly and installation of the filter plate and the cumbersomeness of the operation will be increased. If it is cleaned too late, the circulation and filtering effect of the fluid will be affected. Utility Model Content

[0033] Example 1

[0034] See also Figure 1-Figure 5 , a new type of pressure regulating valve shown in the figure includes a valve body 101 and a liquid inlet pipe 104 connected to the liquid inlet end of the valve body 101 through a first flange 102 and a second flange 103, a filter plate 105 is provided on one side of the valve body 101 close to the liquid inlet end, and also includes an early warning mechanism arranged on the first flange 102 for early warning of the accumulation of debris on the surface of the filter plate 105;

[0035] The early warning mechanism includes a mounting hole 201 opened on the side of the first flange 102 close to the second flange 103, two early warning tubes 202 symmetrically arranged are fixedly connected to the bottom wall of the mounting hole 201, early warning plates 203 are slidably connected in the two early warning tubes 202, distance sensors 204 of model AC-M18-A50 / 100 are arranged on the bottom walls of the two early warning tubes 202, the detection ends of the two distance sensors 204 are arranged opposite to the early warning plate 203, and an early warning lamp 205 is arranged on the valve body 101, and the two distance sensors 204 are electrically connected to the early warning lamp 205 through a controller;

[0036] It should be noted here that: through the setting of the early warning mechanism, under the fixing action of the fixing mechanism, while ensuring the convenience of installation and disassembly of the filter plate 105, under the early warning action of the early warning light 205, the staff is warned to clean the filter plate 105, thereby improving the timeliness of cleaning the filter plate 105, avoiding frequent disassembly or assembly or affecting the circulation and filtering effect of the fluid due to cleaning the filter plate 105 too early or too late, thereby improving the filtering effect of the filter plate 105.

[0037] It is worth noting that: as a prior art, the specific structure and working principle of the pressure regulating valve have been mastered by people in this field, and will not be elaborated here.

[0038] See also Figure 4 The two warning tubes 202 shown in the figure are slidably connected with sliding rods 206, one end of the two sliding rods 206 is connected to the warning plate 203, and the other end of the two sliding rods 206 is fixedly connected with a mounting plate 207, and the two mounting plates 207 are provided with a fixing mechanism for fixing the filter plate 105;

[0039] It should be noted here that the filter plate 105 can be easily installed and fixed by providing the sliding rod 206 and the mounting plate 207 .

[0040] See also Figure 4 , the two warning tubes 202 shown in the figure are provided with first springs 3, and the two ends of the two first springs 3 are respectively connected to the warning plate 203 and the bottom wall of the warning tube 202;

[0041] It should be noted here that the provision of the first spring 3 facilitates the resetting of the warning plate 203 .

[0042] Working principle: When the valve body 101 is in use, the filter plate 105 is first installed at the liquid inlet end of the valve body 101 by using a fixing mechanism, and then the fluid can flow. During the fluid flow, the impurities in the fluid will be filtered by the filtering action of the filter plate 105, thereby ensuring the cleanliness of the fluid;

[0043] During the long-term filtration of the fluid by the filter plate 105, impurities in the fluid will adhere to the surface of the filter plate 105. As the impurities continue to accumulate, the resistance of the fluid passing through the filter plate 105 will increase, so that under the pressure of the fluid, the filter plate 105 will be pushed away from the liquid inlet pipe 104. During the movement of the filter plate 105, the early warning plate 203 will be pushed to slide in the early warning pipe 202 under the action of the driving force. When the distance sensor 204 detects that the moving distance of the early warning plate 203 exceeds the set distance, an electrical signal will be sent to the controller, so that under the action of the controller, the early warning light 205 flashes and emits a buzzing sound. Under the early warning effect of the early warning light 205, the staff is warned to clean the filter plate 105, thereby improving the timeliness of cleaning the filter plate 105, avoiding frequent disassembly and assembly or affecting the circulation and filtering effect of the fluid due to cleaning the filter plate 105 too early or too late, thereby improving the filtering effect of the filter plate 105.

[0046] It should be noted here that: through the setting of the fixing mechanism, utilizing the connection between the first flange 102 and the second flange 103, under the drive of the driving mechanism, the two fixing plates 403 will be pushed to move away from each other, so that under the blocking effect of the two fixing plates 403, the filter plate 105 is installed. When the filter plate 105 is disassembled, it is only necessary to remove the bolt connection between the first flange 102 and the second flange 103 and separate the first flange 102 and the second flange 103 to release the limit on the filter plate 105. The operation is simple and the implementation is convenient, thereby ensuring the convenience of installation and disassembly of the filter plate 105.
