Multipurpose thimbleshaped valve respiration valve

Abstract

The invention discloses a multipurpose cap-shape valve respiratory valve, comprising a valve seat, a valve core and a fixed sleeve; the valve core is of cap shape and made of elastic rubber; the cap rim of the valve core is fixed between the valve seat and the fixed sleeve; the cap body is sheathed in the central hole of the valve seat or the fixed sleeve; furthermore, the top of the cap of the valve core is provided with at least two lancings so that at least one valve clack is formed at the top of the cap. the lancings are distributed all around in a radial pattern from the axle center projected at the top of the cap to form a taper angle shape valve clack, or a C shape, V shape, U shape or opening polygon shape valve clack to cause the end part projected at the top of the cap to form a flip-shell valve clack or cause the lateral side projected at the top of the cap to form at least two valve clacks. The invention has the advantages of simple structure, few faults, long service life, low manufacturing cost, multiple functions and extensive usage, is favorable for environment protection, and has good social and economical benefits.

Description

1. Technical field: [0001] The invention relates to a breathing valve, in particular to a multipurpose hat-shaped valve breathing valve. 2. Background technology: [0002] At present, the basic structure of the known breathing valve is that two one-way valves in opposite directions are butted together, one end is connected to the pipeline or container through a pipeline, and the other ends of the one-way valve are respectively communicated with the outside world. The two valves are commonly referred to as the exhalation valve and the inhalation valve. The spring limit valve plate of the exhalation valve is supported inward by springs, so that the blades fit and close with the valve seat; the spring limit valve plate of the suction valve is supported outward by springs, so that the blades fit and close with the valve seat. The basic principle is: the working principle of the breathing valve is to use a spring limit valve plate, which is determined by the positive and negativ...

AI Technical Summary

Problems solved by technology

When the pressure inside the container is within the range of the two spring elastic values ​​of the exhalation valve, the spring limit valve plate is closed; when the pressure inside the container is greater than the spring force of the exhalation valve, the valve plate opens to release the pressure; when the pressure inside the container is less than When the spring of the suction valve is elastic, the valve plate is opened to pressurize. The first disadvantage is: when used in a high-temperature scale environment, the spring, the limit valve plate, and the valve seat are prone to fouling, which reduces or even loses the elasticity of the spring. 1. The valve seat is not tightly sealed, and the scaling is stuck, resulting in the limit valve plate not moving in place, making it difficult to open or close, resulting in leakage. The second disadvantage is: when used in an acid-base environment, the spring, limit valve It is prone to rust and reduces the elasticity of the spring, causing the limit valve plate to not move in place, making it difficult to open or close, and even causing accidents; the third disadvantage is that when there are suspended particulate matter in the liquid, it is easy to cause the valve to get stuck and blocked. cause failure; the fourth disadvantage is: complex structure, high manufacturing cost, high failure rate, short life, and great accident hazard; the fifth disadvantage is: single function, only suitable for specific devices
