Problems solved by technology

[0002] At present, the pressure regulators commonly used in the market have poor automatic adjustment stability, large fluctuations in air supply pressure, and most of the pressure regulator valve seats and air inlets are manufactured in segments and sealed with rubber. However, for high-pressure regulators Said that the working pressure can reach up to 20MPa, the rubber seal is far from meeting the requirements, the metal seal is used, the machining accuracy and assembly requirements are very high, and the coaxiality of the valve seat is difficult to guarantee, thus affecting the sealing performance of the entire pressure regulator

Abstract

The invention discloses a high-pressure automatic pressure regulator, comprising a valve block provided with a one-way valve component, a safety valve component, a breaker valve component and a regulating valve component. The one-way valve component includes a gas inlet tube connector, a one-way valve and a gas outlet tube connector which are communicated with one another; the intake end of the gas inlet tube connector is connected with an air compressor; the exhaust end of the gas inlet tube connector and the intake end of the one-way valve are communicated with the breaker valve component; the breaker valve component is communicated with the safety valve component and the regulating valve component; the regulating valve component is communicated with outside air; the regulating valve component, the exhaust end of the one-way valve and the intake end of the gas outlet tube connector are sealed via pistons; the exhaust end of the gas outlet tube connector is connected with an operatingend. The high-pressure automatic pressure regulator provides an automatic regulation function and a stable pressure supply function; regulating and stabilizing upon high pressure are more efficient;a valve seat and a gas inlet are integrated, coaxiality of the valve seat is improved, and tightness of the whole regulator is improved.

Description

technical field [0001] The invention relates to the technical field of voltage regulators, in particular to a high-pressure automatic voltage regulator. Background technique [0002] At present, the pressure regulators commonly used in the market have poor automatic adjustment stability, large fluctuations in air supply pressure, and most of the pressure regulator valve seats and air inlets are manufactured in segments and sealed with rubber. However, for high-pressure regulators Said that the working pressure can reach up to 20MPa, the rubber seal is far from meeting the requirements, the metal seal is used, the machining accuracy and assembly requirements are very high, and the coaxiality of the valve seat is difficult to guarantee, thus affecting the sealing performance of the entire pressure regulator. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a high-pressure automatic voltage regu...
