[0022] like Figure 1 As shown, the split pressure regulating valve of the utility model comprises a valve seat 1, a housing 6 and a valve core assembly;

[0023] The valve seat 1 and the shell 6 are prefabricated separately, and then the shell 6 is fixed to the upper end of the valve seat 1 by the retaining spring 4; specifically, slots for inserting the retaining spring 4 are reserved on the overlapping surfaces of the valve seat 1 and the shell 6, and after the retaining spring 4 is inserted into the aligned slots, the position of the retaining spring 4 can be rotated to achieve retaining.

[0024] The pressure regulating valve of the utility model adopts a split structure of the valve seat 1 and the housing 6 as a whole, which is simple to open the mold, improves the machining efficiency, and effectively improves the production efficiency by about 20%. At the same time, the depth of the internal space of the valve seat 1 and the housing 6 is reduced, and the processing of the inside of the valve seat 1 and the housing 6 is easier and more convenient, which simplifies the internal processing technology of the valve body, and the qualified rate of the regulating valve is also improved to more than 99%.

[0025] In this embodiment, the outer surfaces of the valve seat 1 and the housing 6 are both sleeved with sealing rings 8 and 3 for sealing with the connected pipeline, thereby effectively achieving sealing.

[0026] The valve core assembly is installed in the axial hole that passes through the valve seat 1 and the middle of the housing 6. Specifically, the valve core assembly includes a valve core 2, a spring seat 5, a spring 7 and a regulator 13; the valve core 2 is arranged in the valve seat 1 and is located between the water inlet and the water outlet of the valve seat, the spring seat 5 is arranged at the end of the valve core 2, the spring seat 5 is connected to the bottom of the spring 7, the end of the spring 7 is plugged into the inside of the regulator 13, the regulator 13 is arranged in the housing 6, and the end of the regulator 13 extends out of the end of the housing 6. An O-ring 9 and a retaining ring 10 are installed between the outer surface of the regulator 13 near the bottom and the inner surface of the housing 6 to achieve sealing.
