Medical gas area valve box

Abstract

The invention relates to the field of valve boxes, in particular to a medical gas area valve box. A box body, a controller, a first air inlet pipeline, a second air inlet pipeline, a third air inlet pipeline, a convergence air row, a gas pressure reduction adjusting valve, a flow dividing air row and an air conveying pipeline are included. The convergence air row and the flow dividing air row arein communication through the gas pressure reduction adjusting valve. The air outlet ends of the first air inlet pipeline, the second air inlet pipeline and the third air inlet pipeline communicate with the convergence air row, and the air inlet end of the air conveying pipeline communicates with the flow dividing air row. An air inlet air row is provided with a first air pressure sensor, and the convergence air row is provided with a second air pressure sensor. An emergency air supply pipeline is additionally arranged in the valve box, so that the medical gas source disconnection risk is reduced, each air supply pipeline can be manually opened, and accordingly, the medical gas source disconnection risk is further reduced; and a sound and light alarm can be used for guiding a worker to adjust the gas pressure reduction adjusting valve, and the air pressure value in the flow dividing air row conforms to the total air pressure value required by the opened air conveying pipeline.

Description

technical field [0001] The invention relates to the field of valve boxes, in particular to a valve box in a medical gas area. Background technique [0002] The gas manifold is suitable for enterprises with large gas consumption. Its principle is to input bottled gas to the main pipeline of the manifold through clamps and hoses. After decompression and adjustment, it is transported to the use site through pipelines. It is widely used in hospitals , chemical industry, welding, electronics and scientific research units. The basic performance of the gas manifold connects the gas from multiple steel cylinders to the main manifold through the conduit, and after decompression and stabilization, it is transported to the special equipment by the pipeline to the place of use, so as to ensure that the pressure of the gas source of the gas appliance is stable and adjustable. Generally, there are two One group of gas cylinders, one group of gas supply, one group of backup, manual or aut...
