Embodiment 1

[0040] The stop valve provided by the present invention, such as Figure 1 to Figure 2 As shown, it includes a valve body component, a sealing component and an executive component; the valve body component includes a valve seat 2, a valve cover 7, a first valve body 1, a second valve body 16, a valve disc 3 and a valve stem 4; the valve seat 2 has The first cavity, the first opening, the second opening, and the third opening; the valve cover 7 is fixed on the valve seat 2 to close the first opening; the first valve body 1 communicates with the second opening, and the second valve body 16 Connected with the third opening; the valve flap 3 is connected with the valve stem 4, the valve flap 3 is arranged in the first cavity, and the end of the valve stem 4 away from the valve flap 3 extends out of the valve cover 7; the actuator is connected with the valve stem 4 for Drive the valve flap 3 toward or away from the second opening to close or open the second opening; the sealing assem...

Embodiment 2

[0086] The hydrogen-oxygen recombination system provided in this embodiment includes the shut-off valve described in Embodiment 1. When the valve flap 3 moves away from the second opening, the second opening is opened and the medium flows into the first cavity. Because the bellows 5 can be compressed and abut the valve cover 7, it can seal the valve stem 4 and the valve cover 7. The gap between the valve cover 7 and the valve seat 2 is provided with a gasket 6 to seal the gap between the valve cover 7 and the valve seat 2. In addition, the packing 8 can seal the valve stem 4 and the valve cover 7 again The gap between them can reduce the leakage of the medium, and the gasket 6 and the bellows 5 are made of radioactive shielding materials, which can control the leakage of radioactive materials to the outside, so as to meet the requirements of the hydrogen-oxygen recombination system. Run safely and smoothly.

Abstract

The invention provides a stop valve and a hydrogen-oxygen recombination system and relates to the technical field of valves. The stop valve comprises a valve body assembly, a sealing assembly and an executing assembly, wherein the valve body assembly comprises a valve seat, a valve cover, a first valve body, a second valve body, a valve clack and a valve rod; the sealing assembly comprises a corrugated pipe, a gasket and filler; the corrugated pipe is made from a metal material, the corrugated pipe is arranged on the valve rod in a sleeving mode, the corrugated pipe is located in a first cavity, and the corrugated pipe can be compressed when the valve clack moves far away from a second opening, and the corrugated pipe leans against the valve cover; the gasket is made from a silver materialand is arranged between the valve cover and the valve seat; and the filler is arranged between the valve rod and the valve cover. The gasket and the corrugated pipe are made from radioactive shielding materials, and the leakage amount of radioactive substances to the outer side can be controlled, so that the using demand on the hydrogen-oxygen recombination system is met, and the hydrogen-oxygenrecombination system operates safely and stably.

Description

Technical field [0001] The present invention relates to the technical field of valves, in particular to a shut-off valve and a hydrogen-oxygen composite system with the shut-off valve. Background technique [0002] Pneumatic stop valve plays a very important role in the hydrogen-oxygen composite system and is used in the pipeline of the high-temperature hydrogen-oxygen composite system. The ring that passes through the stop valve in the hydrogen-oxygen composite system is mainly high-temperature helium and hydrogen containing solid medium and radioactivity, and its penetration is very strong, so the sealing performance of the stop valve is very high. [0003] However, the stop valve in the prior art is sealed by sealing materials such as graphite or asbestos, which is likely to cause radioactive leakage. Therefore, the stop valve in the prior art cannot meet the requirements of the hydrogen-oxygen composite system, and cannot make the hydrogen-oxygen composite system operate safel...
