Problems solved by technology
The structure of the existing constant pressure valve is complicated, and when it loses its function due to failure, it is often easy to cause the valve to be completely closed. In this way, it is easy to cause the pressure of the fluid to continuously rise to a dangerous level due to the inability to discharge it in time. high pressure

The present invention relates to a constraint pressure valve. It is characterized by that it is made up by using a tube and an elastic plastic or rubber flexible hose which is placed in the tube interior and whose two ends are sealed respectively in two ends of said tube, on the side wall of said tube a gas inlet is set.
Description
Technical field: [0001] The invention relates to a valve. Background technique: [0002] The function of the constant pressure valve is that when the fluid pressure in the system reaches the set value, the constant pressure valve starts to act to make the fluid pass through the constant pressure valve, thus ensuring that the fluid has a certain pressure before passing through the constant pressure valve. The structure of the existing constant pressure valve is complicated, and when it loses its function due to failure, it is often easy to cause the valve to be completely closed. In this way, it is easy to cause the pressure of the fluid to continuously rise to a dangerous level due to the inability to discharge it in time. of high pressure. Invention content: [0003] The object of the present invention is to provide a safe constant pressure valve which has a simple structure and will not completely close the valve even if the valve fails. [0004] The present invention ...
