Description

Technical Field

[0001] The utility model relates to the technical field of air pressure regulation, in particular to a pressure regulating device for compressed air delivery. Background Art

[0002] An air valve is a special valve designed to prevent negative pressure within a pipeline caused by transient decompression waves. It is typically installed at high points in the pipeline where dynamic water pressure is low during normal operation and where liquid column separation may occur during transient flow. Air is drawn in when the pressure in the pipeline falls below atmospheric pressure and exhausted when the pressure rises above atmospheric pressure. During the exhaust process, the valve automatically closes when the liquid in the pipeline fills the pipeline, preventing the liquid from escaping into the atmosphere.

[0003] Chinese patent publication number CN205781154U discloses a pressure regulating device. The technical solution provided in the patent document is as follows: it includes a housing with a valve opening at the bottom, an exhaust hole on the housing, a valve plate and a spring acting on the valve plate within the housing; a pressure rod constrained within the housing that can only move up and down, a threaded hole at the center of the pressure rod, a transmission threaded rod threadedly connected within the threaded hole, a pointer connected to the top of the transmission threaded rod for rotating the transmission threaded rod, the pointer exposed from the top of the housing for easy manual tightening, a scale corresponding to the pointer indicating the air pressure required to open the valve plate at the top of the housing, the upper end of the spring supported on the pressure rod, and the lower end of the spring supported on the valve plate. It is a pressure regulating device with adjustable safety pressure that can be used for inflatable products or equipment, and can also be used as a safety pressure measuring tool.

[0004] In order to solve the problem that the safety pressure of the safety valve of the existing device cannot be adjusted, the existing technology uses the rotation of the pointer to drive the transmission threaded rod to rotate, and according to the principle of threaded transmission, drives the pressure rod to move up and down, thereby adjusting the elastic force applied by the spring to the valve plate, and finally achieving the size of the air pressure required to open the valve port. However, there is still a problem that wear and tear on the outside of the device body cannot be avoided, which leads to a problem of reduced service life. Utility Model Content
