Technical Field

[0001] The utility model belongs to the technical field of pressure regulating valves, in particular to a split regulating valve which is easy to clean. Background Art

[0002] The core technology of the existing piston-type flow and pressure regulating valve is the opening method of the regulating component. There are three main types: spray hole type, slot type and fan blade type. Among them, the spray hole type and slot type are widely used in various working conditions and have good regulation and pressure reduction performance. However, with the emergence of various applications, especially the large-scale application in raw water systems, the blockage of these orifices has become an industry problem. When the orifice is blocked by debris, the valve basically loses its regulating function. Therefore, cleaning the blocked orifice has become a key and difficult point in engineering applications.

[0027] The end of the upstream valve body 1 is provided with a plurality of evenly distributed first mounting holes along the circumference; the end of the downstream valve body 2 is provided with a plurality of evenly distributed second mounting holes along the circumference; the end of the upstream valve body 1 and the end of the downstream valve body 2 are connected by a first mounting bolt 5.

[0028] The valve core 3 and the throttling sleeve 4 are arranged on one side of the valve body pipeline through the valve core 3 bracket, and the valve core 3 and the throttling sleeve 4 are connected by bolts; one end of the telescopic adjustment component is connected to the downstream valve body 2, and the other end of the telescopic adjustment component is installed on the pipeline by bolts; after the upstream valve body 1 and the downstream valve body 2 are disassembled, the positions of the valve core 3 and the throttling sleeve 4 remain unchanged.

[0029] The telescopic adjustment assembly includes a telescopic sleeve 6, a guide cylinder 7, and a guide rod 8; one end of the telescopic sleeve 6 is sleeved on the guide cylinder 7, and the other end of the telescopic sleeve 6 is connected to the downstream valve body 2 through a second mounting bolt 12; one end of a plurality of guide rods 8 is circumferentially arranged on the guide cylinder 7, and the other ends of a plurality of guide rods 8 pass through the telescopic sleeve 6 and the downstream valve body 2; the guide cylinder 7 is connected to the upstream valve body 1.

[0030] The downstream valve body 2 and the telescopic sleeve 6 are both provided with sliding holes 9 through which a plurality of guide rods 8 can pass; the guide rods 8 limit the telescopic sleeve 6 through the first nut 11 .

[0031] The telescopic adjustment assembly further comprises a telescopic flange 10 , which is arranged at an end away from the throttling sleeve 4 through an adjusting rod 13 , and the telescopic flange 10 can slide on a plurality of guide rods 8 .
