Automatic pressure reducing flow stable valve

Abstract

The disclosed steady flow valve includes valve body, valve core, liquid inlet, and liquid outlet. Characters are that spring cavity, inlet cavity and outlet cavity is setup in inner cavity of valve body; current limiting hole is setup between inlet cavity and outlet cavity; a through hole is setup between spring cavity and inlet cavity, and area of the through hole is larger than area of the current limiting hole; elastic seal membrane piece is at left side of the through hole, moveable piston withstands left side of the elastic seal membrane piece, and compression spring is at left side of the moveable piston; push rod withstands right end of the valve core; the seal membrane piece provides thrust force for the push rod, and thrust force of the seal membrane piece is from liquid pressure at liquid outlet cavity. The steady flow valve reduces pressure at output end and stabilizes flux. The valve is suitable to matching water heater and equipment needed decompression and steady flow.

Description

technical field [0001] The invention relates to a valve, in particular to an automatic pressure-reducing and steady-flow valve with functions of reducing outlet pressure and stabilizing flow. Background technique [0002] The function of ordinary valves is to open and close fluid pipelines, and its flow control is generally controlled by adjusting the opening of the valve. But in actual use, the fluid pressure at the inlet end of the valve is usually unstable, so its flow rate is also unstable. Moreover, in most applications, the fluid pressure at the inlet end of the valve or the fluid pressure of the fluid supply pipe network is usually higher than that of the fluid supply network. It is easy to use directly, and the output pressure at the outlet of ordinary valves is usually directly related to the flow rate. Specifically, the larger the flow rate, the smaller the decompression effect, and the larger the output pressure, and vice versa. Therefore, ordinary valves cannot ...

AI Technical Summary

Problems solved by technology

The level of the water temperature is generally achieved by adjusting the channel area of ​​the valve to change the flow of water. However, because the water pressure in the public water pipe network is not stable, the position of the valve adjustment knob is fixed. The size is also not stable, which directly causes the temperature of the hot water to fluctuate, causing users to frequently adjust the valve without much trouble

When the water pressure of the public water pipe network fluctuates too much, it may even affect the normal use of the water heater
