Description

Technical Field

[0001] This utility model relates to the field of pressure reducing valve assembly technology, and in particular to the structure of an adjustable municipal water supply pipeline pressure reducing valve assembly. Background Technology

[0002] A pressure reducing valve assembly is a complete set of devices used to control the pressure of fluids (such as gas and liquid). It consists of multiple components working together to stably reduce the higher pressure upstream to the set pressure required downstream, and maintain the stability of the downstream pressure when operating conditions change. It is widely used in water supply and drainage, HVAC, gas supply, industrial production and other fields, and is a key component to ensure the safe operation of the system and the normal operation of the equipment.

[0003] Although existing pressure reducing valve assemblies are equipped with a filter structure, their filter structure cannot simultaneously perform pressure reduction adjustment and emergency shut-off, resulting in poor functionality. Utility Model Content

[0004] This utility model relates to the structure of an adjustable municipal water supply pipeline pressure reducing valve assembly, which solves the problem that although the existing pressure reducing valve assembly is equipped with a filter structure, its filter structure cannot simultaneously perform pressure reduction adjustment and emergency interception, resulting in poor functionality.

[0005] This utility model provides an adjustable municipal water supply pipeline pressure reducing valve assembly structure, specifically including: a filter box; a cover plate is fixed on the filter box, an inlet pipe is fixed on the left end face of the filter box, a discharge pipe is fixed on the right end face of the filter box, a filter plate is fixed inside the filter box, and filter holes are equidistantly opened on the filter plate; two electric cylinders are symmetrically fixed on the right end face of the filter box, and the extended ends of the two electric cylinders are fixed on the mounting bracket. Unblocking rods are welded equidistantly on the mounting bracket, the unblocking rods are aligned with the filter holes, and one end of the unblocking rod is a pointed structure.

[0006] Preferably, a connecting pipe is connected to the discharge pipe, a pressure reducing valve is installed on the connecting pipe, and a first pressure gauge is installed on the connecting pipe, with the first pressure gauge located to the left of the pressure reducing valve.

[0007] Preferably, a first shut-off valve is installed on the pressure reducing valve, and the first shut-off valve is located to the left of the first pressure gauge.

[0008] Preferably, the connecting pipe is connected to three branch pipes, and each branch pipe is equipped with a second pressure gauge.

[0009] Preferably, each of the diversion pipes is equipped with a second shut-off valve, and the three second shut-off valves are located to the left of the three second pressure gauges.

[0010] Preferably, a sealing rod is welded onto the mounting bracket, and the sealing rod is aligned with the discharge pipe. When the electric cylinder retracts, the sealing rod contacts the discharge pipe.

[0011] This utility model provides an adjustable pressure reducing valve assembly structure for municipal water supply pipelines, which has the following beneficial effects:

[0012] 1. The filter plate and the unblocking rod in the filter box of this application form a linkage adjustment mechanism. The unblocking rod is driven by an electric cylinder to precisely align with the filter holes. It can not only efficiently remove blockages through the pointed structure to ensure smooth water flow, but also change the actual flow area of ​​the filter holes by adjusting the insertion depth of the unblocking rod, so as to flexibly control the filtration accuracy and flow capacity. At the same time, the change in flow volume can achieve preliminary water pressure adjustment, reducing the load on the subsequent pressure reducing device.

[0013] 2. The pressure reduction and monitoring system of this application has a reasonable layout. The pressure reducing valve on the connecting pipe can stably reduce the water pressure. The first pressure gauge on the left side provides real-time feedback on the pressure status before pressure reduction, which facilitates timely monitoring of the system's operating condition. The first shut-off valve is located between the pressure gauge and the pressure reducing valve, which can quickly cut off the water flow during maintenance, avoiding water waste and operational risks. Furthermore, the diversion structure design takes into account both functionality and ease of maintenance. Each of the three diversion pipes is equipped with a second pressure gauge and a second shut-off valve, which not only enables independent monitoring of the pressure of each branch to ensure water supply stability, but also allows for safe replacement of the pressure gauge by closing the shut-off valve, reducing the impact of maintenance on the overall system.

[0014] 3. The emergency interception mechanism of this application improves the reliability of the system. The sealing rod on the mounting bracket is precisely aligned with the discharge pipe. When the first shut-off valve fails, the electric cylinder retracts to drive the sealing rod to achieve a mechanical seal, forming a double interception guarantee and effectively avoiding the problem of failure to intercept due to the failure of a single valve.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes an adjustable municipal water supply pipeline pressure reducing valve assembly structure, including: a filter box 1; a cover plate 101 is fixed on the filter box 1, an inlet pipe 102 is fixed on the left end face of the filter box 1, a discharge pipe 103 is fixed on the right end face of the filter box 1, a filter plate 104 is fixed inside the filter box 1, and filter holes 105 are equidistantly opened on the filter plate 104; two electric cylinders 2 are symmetrically fixed on the right end face of the filter box 1, and the extended ends of the two electric cylinders 2 are fixed on the mounting bracket 201. Unblocking rods 202 are welded equidistantly on the mounting bracket 201, the unblocking rods 202 are aligned with the filter holes 105, and the left end of the unblocking rods 202 is a pointed structure. When unblocking the filter holes 105 and adjusting the size of the filter holes 105, the electric cylinders 2 can be driven to extend. By adjusting the position of the unblocking rods 202, the unblocking of the filter holes 105 and the size of the filter holes can be adjusted, and the water pressure can also be adjusted.

[0029] The discharge pipe 103 is connected to a connecting pipe 3, a pressure reducing valve 5 is installed on the connecting pipe 3, and a first pressure gauge 7 is installed on the connecting pipe 3. The first pressure gauge 7 is located to the left of the pressure reducing valve 5. When in use, the pressure reducing valve 5 can reduce the pressure, and the first pressure gauge 7 can be used to monitor the water pressure in a timely manner.

[0030] The pressure reducing valve 5 is equipped with a first shut-off valve 6, which is located to the left of the first pressure gauge 7. When in use, the first shut-off valve 6 can be used to intercept the liquid, which facilitates the maintenance of the pressure reducing valve 5.

[0031] Among them, the connecting pipe 3 is connected to three diversion pipes 4, and each diversion pipe 4 is equipped with a second pressure gauge 9. In use, the pressure at the diversion pipe 4 can be detected by the three second pressure gauges 9.

[0032] Each diversion pipe 4 is equipped with a second shut-off valve 8. The three second shut-off valves 8 are located to the left of the three second pressure gauges 9. In use, the diversion pipe 4 can be blocked by the three second shut-off valves 8, which makes it convenient to replace the second pressure gauges 9.

[0033] Example 2, based on Example 1, such as Figures 1 to 6 As shown, a sealing rod 203 is welded onto the mounting bracket 201. The sealing rod 203 is aligned with the discharge pipe 103. When the electric cylinder 2 retracts, the sealing rod 203 contacts the discharge pipe 103. In use, the retraction of the electric cylinder 2 can drive the sealing rod 203 to move, thereby achieving the interception of the discharge pipe 103 through the sealing rod 203, avoiding the phenomenon of failure to intercept due to damage to the first shut-off valve 6.

[0034] The working principle of this embodiment is as follows: When cleaning and adjusting the size of the filter hole 105, the electric cylinder 2 is extended. The position adjustment of the cleaning rod 202 can achieve the cleaning of the filter hole 105 and the adjustment of the filter size, and can also achieve water pressure adjustment. In case of emergency interception, the electric cylinder 2 is retracted. The retraction of the electric cylinder 2 can drive the sealing rod 203 to move, and the sealing rod 203 can then intercept the discharge pipe 103.
