The cylinder valve high pressure

 

(57) Abstract:

The valve is to shut-off devices for high-pressure cylinders. The valve includes a housing with a fitting for connection to the breathing apparatus and the control rod to move the valve. Installed in the housing radial seal. The rod is provided with radial and axial channels. When closed, the valve radial channel is above the seal and reports the cavity connecting the fitting with the environment, and when you open the valve below the seal, blocking the message cavity connecting the fitting with the environment. The valve is located on the side of the working pressure and is spring-loaded. The valve allows you to easily and safely remove the cylinder, for example, when replacing it with a new breathing apparatus. 2 Il.

The invention relates to locking devices for high-pressure cylinders used, for example, in breathing apparatus designed for individual protection of respiratory organs and eyes of a person from the harmful effects of aggressive environment during routine and emergency operations.

Known cylinder valve high pressure, comprising a housing with a socket for connection of, for example, to the apparatus is s working pressure (DE 807346 A. 28.06. 1951).

The disadvantage of this construction is that after closing the valve in the cavity connecting fitting remains working air pressure, which complicates the undocking of the valve cylinder from the breathing apparatus, for example, when replacing with the new one, requiring great effort and making it unsafe, especially in an emergency situation.

Technical result achieved in the implementation of this invention is to create a cylinder valve high pressure high reliability.

This technical result is achieved in that the cylinder valve high pressure, comprising a housing with a socket for connection of, for example, to the breathing apparatus and the handwheel with the rod for opening and closing the spring-loaded valve located on the side of the working pressure, according to the invention provided with a radial seal positioned in the housing, and the rod-side valve contains interconnected axial and radial channels, and when closed, the valve radial channel is above the seal for the message cavity connecting the fitting with the environment, and when you open the valve below the seal, to overlap the cavity of the treatment tip can the Ana in the drawing, where:

in Fig. 1 shows a General view of the valve in the closed valve;

in Fig. 2 - General view of the valve in an open valve.

The valve consists of a housing 1 with a connecting fitting 2, a seat 3 and a radial seal 4, shaft 5, the bottom of which is made 6 axial and radial 7 channels, and in the upper part of the fixed wheel 8. The rod in the middle part has a through channel 9 and the thread by which it is moved in the housing. In the upper part of the body has hard nut 10, and the lower part is spring-loaded valve 11. Lower the body cavity communicated with the cavity of the connecting fitting through channel 12.

Operates the valve as follows. Turning the handwheel 8 clockwise moving the rod 5 up until it stops in the nut 10. The valve 11 under the action of the spring and the pressure in the cylinder (shown conventionally) moves with the rod 5 and sits on the seat 3. Thus, the valve closes. When this radial channel 7 is moved above the seal 4 and will automatically inform the cavity connecting the nozzle 2 through the channels 12, 6, 7, and 9, and also the gaps between the rod 5 and the nut 10, the flywheel 8 and the outer surface of the housing 1 with the environment.

Thus, the fitting is automatically discharged to a value of the ambient pressure. Therefore, you can easily and safely remove the valve from the container, for example, when replacing the new one in the breathing apparatus. This is especially important in an emergency situation.

Turning the handwheel 8 counterclockwise moving the rod 5 downward until it stops in the housing 1. When this radial channel 7 in the rod 5 moves below the seal 4 on the connection cavity connecting fitting 2 with the environment, and the lower end of the rod 5 will open the valve 11, providing free passage of air from the cylinder.

The cylinder valve high pressure, comprising a housing with a socket for connection of, for example, to the breathing apparatus and the handwheel with the rod for opening and closing the spring-loaded valve located on the side of the working pressure, characterized in that it is provided with a radial seal positioned in the housing, and the rod-side valve contains interconnected axial and radial channels, and when closed, the valve radial channel is above the seal for the message cavity connecting the fitting with the environment, and when you open the valve below the seal, to overlap the cavity connecting the fitting with the environment.
