Self-reliance type pressure regulating the application and principle of pneumatic valve

type pressure regulating pneumatic valve themselves because they do not need other foreign energy such as electricity, gas, only rely on media's own energy to drive, both energy saving and environmental protection, easy to use, after the installation is set pressure value can be put into automatic operation, so the control accuracy is not high, and the lack of electricity, gas, has been more and more widely used. But in use process, must pay attention to the particularity of selection, otherwise easy to cause accident. In use process, must pay attention to the use of selection and installation environment, therefore, detailed understanding of self-reliance type pressure regulating the working principle and structure of the pneumatic valve is very important.
, purpose and scope of the
self-reliance type pressure regulating pneumatic valve ( Hereinafter referred to as pressure pneumatic valve) Equipped with comprehensive survey, execution, control function. Widely used in petroleum, chemical industry, metallurgy, light industry and other industrial sectors and urban heating, for eh system. This product can be used in the corrosive ( The highest temperature ℃) The media such as liquid, gas, and steam pressure control device.

process, structure and working principle of medium pneumatic valve, pneumatic pressure Pl after pneumatic valve core seat before throttling, to pneumatic valve after pressure P. Pneumatic control valve after pressure. P role in particular of force also will increase. Until a particular force and spring force balance. Making the P down to a set value. This is the working principle of pneumatic pressure regulation valve later. Can adjust the adjusting nut.
and technical features:
self-reliance type pressure regulating pneumatic valve is does not require any additional energy, USES the energy of modulated medium to achieve automatic adjustment of the actuator products. The biggest characteristic of products can work in places where no electricity, no gas, at the same time, save energy, pressure setting can be adjusted freely in the run. Use quick opening traffic characteristics, action quick, sealed performance is good, so it is widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and residential building blocks, all kinds of industrial equipment of all kinds of gas, liquid and steam decompression, medium voltage ( After used in pneumatic valve adjusting) , or pressure, holding pressure ( Used in pneumatic valve adjustment) The automatic control. Attached the condenser can be used in ℃ temperature or less.
