Embodiment 1

[0017] Such as figure 1 As shown, a pressure-adjusting pressure reducing valve includes a power head 1, a valve body 2, a valve core 3, an annular valve seat 4, and an adjusting screw 7. The power head 1 is installed on the annular valve seat 4, and the annular valve There are two seats 4, which are arranged oppositely. The power head 1 is installed on one of the annular valve seats 4, and a valve core 3 is installed between the two annular valve seats 4. A movable valve body is formed in the middle of the valve body 2. The channel for the flow of liquid medium, the contact surface of the valve body 2 and the two annular valve seats 4 and the slow direction of the flange end respectively have an inclination angle of 5-10°, and the two annular valve seats 4 are far away from the power head 1. One end is provided with adjusting screw 7.

[0018] Preferably, the power head 1 is a handle structure.

[0019] Preferably, the longitudinal sections of the two annular valve seats 4 a...

Abstract

The invention discloses a pressure adjustment type pressure reducing valve. The pressure reducing valve comprises a power head, a valve body, a valve core, two opposite annular valve seats and adjusting screws. The power head is mounted on one of the annular valve seats, the valve core is mounted between the two annular valve seats, and a flow passage allowing a liquid medium to flow is formed in the middle of the valve body. An inclination angle of 5-10 degrees is formed between a contact face of the valve body with each of the two annular valve seats and a flange end slow direction, and one end, away from the power head, of each of the two annular valve seats is provided with one adjusting screw. According to the technical scheme, by arrangement of the adjusting screws, the opposite position of the valve core to the valve body can be adjusted, a gap between each valve seat and the valve core can be partially adjusted, and an integral valve starting torque can be adjusted as well.

Description

technical field [0001] The invention relates to the technical field of valve accessories, in particular to a pressure-adjusting pressure reducing valve. Background technique [0002] Pressure reducer, because the pressure in the gas cylinder is high, but the pressure required for gas welding and gas cutting and the point of use is relatively small, so a pressure reducer is needed to reduce the high-pressure gas stored in the gas cylinder to low-pressure gas , and should ensure that the required working pressure remains stable throughout. In short, the pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and keeps the pressure and flow of the output gas stable. However, the existing valves cannot be adaptively adjusted according to the adjustment of the fluid flow rate, and cannot meet the needs. [0003] Based on this, research and development of a pressure regulating pressure reducing valve. Contents of the invention [0004] The i...
