Problems solved by technology

The traditional pressure regulating device is mainly composed of a flexible diaphragm, a rigid diaphragm and a pressure regulating spring. The spring is used to balance the air pressure in the diaphragm cavity to adjust the pressure. Since the spring force has a linear relationship with the displacement, the pressure regulating spring cannot be quickly and quickly. Stable Regulated Gas Pressure

Abstract

The invention discloses a pressure regulating device and a pressure regulator thereof. The pressure regulating device comprises a membrane cavity and a magnetic module. The membrane cavity comprises a flexible membrane (11), a rigid membrane (12), a membrane shaft (13) fixedly connected with the flexible membrane (11) and the rigid membrane (12), a pressure regulating spring seat (14) and a pressure regulating spring (15). One end of the pressure regulating spring (15) is sleeved on the pressure regulating spring seat (14), and the other end of the pressure regulating spring (15) is butted against the rigid membrane (12). The magnetic module comprises a pair of magnetic parts (21 and 22) subjected to magnetic force. The magnetic parts (21 and 22) and the pressure regulating spring (15) are arranged on the same axis (18) in a linkage manner. The pressure regulating device and the pressure regulator thereof has the advantages of short balance cycle, stable outlet pressure, low closing pressure, safety, quickness and stability.

Description

technical field [0001] The invention relates to the field of decompression and pressure regulators, in particular to a pressure regulating device and a pressure regulator with short balance period, stable outlet pressure value, low closing pressure value, safety, speed and stability. Background technique [0002] The main principle of the pressure regulator is throttling. After the high-pressure gas enters the pressure regulator, the pressure opens the valve seat, the flow rate increases, the gas enters the diaphragm cavity, and the pressure in the cavity increases, so that the pressure acting on the diaphragm increases. , and overcome the spring force outside the diaphragm to change the opening of the valve flap to achieve dynamic balance, so that the pressure of the gas in the main diaphragm cavity meets the set value. The pressure regulating device is the core and key component of the pressure regulator, which is used to adjust the high-pressure gas entering from the air ...
