Panel type angle stop valve for oxygen cabin

Abstract

The invention provides a panel type angle stop valve for an oxygen cabin. The panel type angle stop valve comprises a valve body, a first sealing gasket, a valve rod, a mounting panel, a valve fixing seat, a sealing nut and a locking nut. The first sealing gasket is arranged in the valve body. The upper end of the valve rod is arranged outside the valve body, and the lower end extends into the valve body from a valve hole and is detachably connected with the first sealing gasket. The valve fixing seat is in threaded connection with the valve rod. The top of the sealing nut is integrally fixed at the bottom of the valve fixing seat, and the bottom of the sealing nut is screwed into the valve hole. The locking nut is in threaded connection with the upper portion of the valve fixing seat. According to the panel type angle stop valve, the installation requirements of panels with different thicknesses, various installation angles and any position can be met, the sealing gasket can be replaced on the premise that a pipeline is not affected, the permission of system equipment can be better maintained, and the adverse effect of the valve on a system is greatly reduced. The function that the overall performance of the valve can be recovered only by replacing the sealing gasket can be achieved, the maintenance cost is reduced, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of supply and exhaust devices for oxygen chambers, and in particular relates to a panel-type angle stop valve for oxygen chambers. Background technique [0002] Oxygen chamber refers to a manned pressure vessel that uses breathable gas such as air, oxygen or mixed gas as the pressure medium, and is used for the treatment and adaptive training of personnel in the chamber. It is listed in category A5 in the national catalog of special equipment production licenses. Widely used in hospitals, sanatoriums, health clubs, etc. for patients to inhale high-pressure oxygen. Under the effect of hyperbaric oxygen, the patient's alveolar oxygen partial pressure increases, blood oxygen content increases, arterial blood oxygen tension also increases correspondingly, and blood oxygen diffusion capacity increases at the same time, which significantly improves the oxygen supply to organs and tissues, and reverses the process...

AI Technical Summary

Problems solved by technology

[0003] Existing stop valves for oxygen chambers are mostly set outside the oxygen chamber, lacking effective support, so that when the valve stem rotates in the valve body, the valve body is also easy to shake with the valve stem, and then the sealing gasket at the bottom of the valve stem is in contact with the valve body. The increase of friction will reduce the service life of the gasket; and because the valve body lacks effective support, the position of the valve body will be affected by the pipeline connected to it, which makes it difficult to meet the installation requirements of various installation angles and arbitrary positions, and it is also difficult to quickly Replacement of gaskets and other sealing components is inconvenient for installation and maintenance, and the maintenance cost is high
