Knob-type pressure regulating valve with pressure gauge and compressor provided with pressure regulating valve

Abstract

The invention belongs to the technical field of fluid machinery, and relates to a structure and layout of a pressure gauge for monitoring and modulating the pressure condition of a fluid medium. The knob-type pressure regulating valve is characterized in that the condition that the pressure gauge and the pressure regulating valve of a traditional fluid mechanical device are of independent structures and in a distributed installation layout mode is improved, and the pressure gauge is accommodated into the pressure regulating valve in another way, thereby integrating the pressure gauge and the pressure regulating valve into one component. A hollow cavity is arranged on the pressure regulating valve to accommodate the pressure gauge for monitoring the pressure condition of the fluid; the pressure regulating valve is provided with pressure regulating components, such as a knob, a spinning sleeve, a pressure regulating core, a pressure regulating piston and a pressure regulating spring for regulating and controlling the output pressure of the fluid medium. Integral structure design and installation layout form are adopted by the pressure gauge and the pressure regulating valve, so that the space occupied by the whole device is more compact, the pressure gauge can be prevented from being crashed and scratched, and meanwhile, the compressor with the pressure regulating valve has higher reliability, smaller volume and a better appearance.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery, and relates to the structure and layout of a knob-type pressure regulating valve, in particular to the structure and layout of a knob-type pressure regulating valve with a pressure indicating gauge, and the structure and layout of the knob-type pressure regulating valve equipped with the regulating valve. Air compressor with pressure valve. Background technique [0002] Fluid machinery is a mechanical device used to transport fluid working medium or increase the pressure of fluid working medium, such as various water pumps, hydraulic pumps, hydraulic motors and air compressors, etc. Machinery. As we all know, in the process of transporting fluid, it is often necessary to monitor and adjust the pressure of the fluid working medium according to the specific requirements of the user. For this reason, setting a pressure regulating valve and a pressure indicating gauge (hereinafter referred ...

AI Technical Summary

Problems solved by technology

[0004] 1) Independently equipped pressure regulating valves and pressure gauges will inevitably have a negative impact on the reliability of the compressor device

This is due to the fact that pressure regulating valves and pressure gauges must be used explicitly, so they can only be designed with an exposed layout. In this way, these components, especially the pressure gauge, are often subject to collisions in frequent mobile operations. and scratches, so that connection failure accidents such as loosening, shifting or even falling off become the norm. In other words, the more exposed components and components, the more the working reliability of the compressor device will be reduced;

[0005] 2) The pressure regulating valve and pressure gauge equipped independently will inevitably have an adverse effect on the compact design of the compressor unit

It is obvious that after the pressure regulating valve and the pressure gauge adopt an independent structure and independent installation, the space they occupy will inevitably increase, which is obviously not conducive to the compact design of the portable air compressor that is strictly limited in volume. That is to say, the more independent structures and independently installed components, the less able to meet the compact design requirements of portable air compressor devices;

[0006] 3) The pressure regulating valve and pressure gauge equipped independently will inevitably have an adverse effect on the appearance design of the compressor device

This is because the exposed layout design of the pressure regulating valve and pressure gauge will inevitably lead to a complicated overall appearance of the compressor device. It is noted that small air compressors are mainly portable, and the limited volume requires that the external shape of the device should not be too much. Only in this way can the cover be designed calmly. Obviously, the more independent structures and components installed independently, the less conducive to the appearance of the compressor

[0007] In summary, the existing independent pressure regulating valves and pressure gauges are very unfavorable for fluid mechanical devices to achieve the layout requirements of high reliability, small volume and beautiful appearance, especially for small air compressors
