Problems solved by technology

[0005] Existing accumulators can only store energy in one direction due to design problems, and regulating valves, as a connection with control capabilities, are sometimes connected in two-way flow pipelines, and in two-way flow pipelines, In order to protect the regulating valve and make the regulating valve work normally, two accumulators need to be installed, which will cause the volume of the regulating valve to become larger and affect the normal assembly of the regulating valve

Embodiment 1

[0044] see Figure 1-2 , an energy storage type two-way pressure regulating valve, including a two-way regulating valve casing 1, and an inlet A2, an inlet B3 and a piston passage 4 are dug on the two-way regulating valve casing 1, and the inside of the two-way regulating valve casing 1 passes through the inlet A2, the inlet B3 and the piston Road 4 is connected with the outside world, and the entrance A2 matches the entrance B3. A sealing piston 5 matching itself is placed in the piston road 4. The upper end of the sealing piston 5 is connected with a torsion bar 6, which is far away from the sealing piston 5. One end runs through the piston passage 4 and extends to the outside of the two-way control valve housing 1. The end of the torsion bar 6 away from the sealing piston 5 is connected to a turntable 7. The turntable 7 is convenient for the staff to adjust the sealing piston 5. The two-way control valve housing 1 is connected with Two-way energy storage ring 8, the two-way...

Abstract

The invention discloses an energy storage type two-way pressure regulating valve, which belongs to the field of two-way regulating valves. An energy storage type two-way pressure regulating valve can reduce the pressure generated in the fluid in the pipeline when the regulating valve is quickly adjusted through the two-way accumulator. For the impact on the regulating valve, since the two-way accumulators have a completely symmetrical layout, the two two-way accumulators can bear the load evenly, so that the wear of the two two-way accumulators is roughly the same, and it is not easy to be affected by the layout of the two-way accumulators. The problem causes excessive loss of a certain two-way accumulator and shortens the working life of the regulating valve. At the same time, through the cooperation of two two-way accumulators, the impact of hydraulic pressure on the regulating valve is reduced, and the impact of high-pressure fluid on the regulating valve is minimized. The scouring loss of the inner wall of the valve and the accumulator greatly reduces the working loss of the regulating valve and accumulator during normal operation, prolongs the service life of the regulating valve and accumulator, and reduces the daily maintenance work of the staff.

Description

technical field [0001] The invention relates to the field of two-way regulating valves, in particular to an energy storage type two-way pressure regulating valve. Background technique [0002] Regulating valve, also known as control valve, is the final control element used in the field of industrial automation process control to change the process parameters such as medium flow, pressure, temperature and liquid level by means of power operation by receiving the control signal output by the regulating control unit. Generally, it is composed of an actuator and a valve. According to the stroke characteristics, the regulating valve can be divided into straight stroke and angular stroke. [0003] The accumulator is an energy storage device in the hydraulic pneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compression energy or potential energy into hydr...
