Embodiment 1

[0026] as attached figure 1 As shown, a pressure controller includes a valve body 1 and a valve core 2 placed therein, and the valve core 2 is hollow. One end of the valve body 1 is provided with a disc-shaped fixed seat 11, and six threaded holes 12 are provided in the circumferential direction. The fixed seat 11 is connected with an outlet valve section 3, which is in the form of a threaded pipe, and the outlet valve section 3 There is a fluid limiter 31 inside, one end of the fluid limiter 31 is clamped on the shoulder 32 in the outlet valve section 3, and the other end is placed in the valve core 2; the outer circumferential direction of the fluid limiter 31 is evenly distributed Stop protrusion 33 is arranged, and the top of spool 2 abuts on the stop protrusion 33 (as Figure 5a , 5b shown). An elastic diaphragm 5 is provided at the joint between the valve core 2 and the valve body 1. One end of the elastic diaphragm 5 is crimped by the outlet valve section 3 and the v...

Embodiment 2

[0029] Such as figure 2 As shown, a pressure controller includes a valve body 1 and a valve core 2 disposed therein. Both ends of the valve body 1 are connected with an inlet valve section 4 and an outlet valve section 3, and an inlet valve section 4 and an outlet valve section 3 All are in the form of French blue plates. The valve body 1 is provided with a fixed seat 11, and the outlet valve section 3 is connected with the fixed seat 11 on the valve body 1 through bolts. The tail end of the valve body 1 is provided with threads, and the inlet valve section 4 is connected with the valve body 1 through threads. At one end of the outlet valve section 3, the valve body 1 and the valve core 2 are sealed by an O-ring 51, and this structure is applied to high pressure occasions. All the other are the same with embodiment 1.

Abstract

The invention relates to a pressure regulator, in particular to a pressure controller applied to a fluid system. It includes a valve body, a valve core is arranged in the valve body, a spring is connected outside the valve core, seals are provided at both ends of the valve core, a number of guide grooves are arranged in the axial direction on the valve body, and the spring is close to the inlet end. One side is provided with an adjusting cap, and the adjusting cap is sleeved on the valve core. The adjusting cap is provided with a number of angles, and the angles are inserted into the guide groove and fit with the guide groove. The present invention mainly provides a pressure controller that can continuously adjust the outlet pressure when the inlet pressure is constant, and has good versatility; it solves the problem that the pressure difference between the inlet and outlet of the pressure controller in the prior art is constant , a technical problem with poor versatility.

Description

technical field [0001] The invention relates to a pressure regulator, in particular to a pressure controller applied to a fluid system. Background technique [0002] Usually, from the pressure supply source to the user end in the fluid system, it is necessary to pass through a pressure controller to adjust the pressure difference between the two, or to perform pressure conversion. After the pressure controller is set, the pressure difference between the inlet and outlet is a fixed value, that is, the outlet pressure is the inlet pressure minus a constant pressure difference. Now the urban tap water supply system adopts mechanical pressurization, so when the tap water reaches each user, the pressure will be different due to the location and time. Some places have high pressure, and some places have low pressure. As people With the improvement of living standards, some devices in the family need no-pressure or low-pressure water supply, such as solar water heaters, etc. In ot...
