Novel automatic decompression voltage and current stabilizer

Abstract

The invention belongs to the technical field of hydraulic transmission and discloses a novel automatic decompression voltage and current stabilizer, wherein a liquid inlet and a liquid outlet are arranged on the side wall of a shell, an upper end cover and a lower end cover are respectively connected on the upper end and the lower end of the shell, a valve seat is arranged at the middle part of the inner cavity of the shell, a valve rod component is inserted in the valve seat, the upper and lower ends of the valve rod component respectively stretch out from the upper and lower ends of the valve seat, the valve rod component stretching out from the upper end of the valve seat divides the inner cavity of the shell into an upper cavity and a lower cavity, which are not communicated with each other, the upper part of the valve rod component is in slide and seal fit with the upper opening of the valve seat, a pressure regulating device is arranged between the valve rod component stretching out from the upper end of the valve seat and the upper end cover, a valve core matched with the pressure regulating device and the valve seat for controlling the liquid pressure and flow rate in the shell is arranged on the valve rod component stretching out from the lower end of the valve seat, the liquid inlet is communicated with the inner cavity of the valve seat, and the liquid outlet is communicated with the lower cavity of the shell. The novel automatic decompression voltage and current stabilizer disclosed by the invention saves energy and water and has good decompression voltage and current stabilization effects, so that the novel automatic decompression voltage and current stabilizer is suitable for such fields as toilet bowl without a water tank.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic transmission, and specifically refers to a new type of automatic decompression stabilizer with the advantages of reducing outlet pressure, stabilizing pressure, stabilizing flow, high adjustment accuracy, adaptable to high and low pressure working environments, small outlet pressure fluctuations and flow changes. pressure regulator. Background technique: [0002] The function of the ordinary valve is to open and close the fluid pipeline, and its flow control is usually controlled by adjusting the opening of the spool. But in actual use, the pressure at the inlet end of the valve is unstable, so its flow rate is also unstable. Moreover, in most cases, the fluid pressure at the inlet end of the valve or the fluid pressure in the fluid supply pipeline is usually high and inconvenient to use directly. The output pressure at the outlet of the valve is usually directly related to the flow rate. Spec...

AI Technical Summary

Problems solved by technology

The existing pressure reducing valves have the following disadvantages: low adjustment accuracy, narrow adaptability to occasions (generally only work in high-pressure or low-pressure environments)

And there are defects such as normal work at high pressure, failure to open at low pressure, normal work at low pressure, poor decompression effect at high pressure, large fluctuations in outlet pressure, large vibration of the valve core, large noise during work, and unstable flow.
