Abstract

The invention discloses a YZ valve pneumatic control box, and relates to the technical field of natural gas valve control. The YZ valve pneumatic control box specifically comprises a box body and hinges; a cabinet door is arranged outside the front end of the box body; a box body bottom plate is installed at the rear end in the box body; a steel pipe is arranged in the box body; a second clamping sleeve check valve is installed in the lower end of the steel pipe; a second AFV director is installed at one end of the outer portion of the second clamping sleeve check valve; and a second stainless steel clamping sleeve tee joint is arranged at the upper end of the second AFV director. According to the YZ valve pneumatic control box, fluid in the steel pipe can be automatically controlled, namely, the hydraulic flowing direction is controlled through the design of an electromagnetic valve in a two-position five-way valve; in a natural gas pipeline, an electromagnetic control reversing valve is used for controlling opening and closing of an airflow channel or changing the flowing direction of compressed air; and the main working principle is that electromagnetic force generated by an electromagnetic coil is utilized to push a valve element to be switched, and therefore reversing of airflow is achieved.

Description

technical field [0001] The invention relates to the technical field of natural gas valve control, in particular to a YZ valve pneumatic control box. Background technique [0002] The gas valve is a new type of safety supporting device for gas pipeline engineering; it is used to cut off, connect and adjust the gas in the pipeline, and has good control characteristics and closing and sealing performance; it is suitable for city gas, liquefied petroleum gas, natural gas, On various gas medium pipelines such as oxygen, valve pneumatic control boxes need to be used during the installation and use of gas pipelines. [0003] The existing natural gas valve control box is inconvenient to perform sufficient anti-backflow treatment on the gas inside the pipeline during use, and it is inconvenient to cut off the natural gas fluid in the pipeline more conveniently. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a YZ valve...
