Abstract
The utility model relates to a sterile-type breather valve which comprises a cylinder body, a seat body and a valve body, wherein the cylinder body and the seat body are fixedly connected and a valve opening is formed on the seat body. The sterile-type breather valve is characterized in that the valve body is cylindrical and hollow, a valve cover is arranged at the upper end of the valve body, an air hole is formed on the side wall of the valve body, an expiration hole is formed at the lower end of the valve body, a movable ball body is arranged at the lower end of the inner side of the valve body, an aspiration spring is clamped on the outer side of the valve body between the valve cover and the seat body, an expiration spring is clamped between the valve cover and the ball body, an air hole is formed on the seat body, and a connecting end is arranged at the lower end of the seat body. The sterile-type breather valve is hermetically and detachably connected with a storage tank through the connecting end, so that the sterile-type breather valve is conveniently assembled or disassembled. When the gas pressure is too large inside the storage tank, the ball body is pushed upwards under the internal pressure of the storage tank; the expiration spring is compressed; and the gas inside the storage tank is discharged through the expiration hole on the lower side of the valve body, then flows into the cylinder body through the air hole on the side wall of the valve body and finally is exhausted through the air hole of the seat body. When the gas pressure is too low inside the storage tank, the ball body is pushed downwards under the pressure, and the external air flows into the storage tank through the air hole on the side wall of the valve body. The sterile-type breather valve has the advantages of simple structure, convenience for disassembly and cleaning and good pressure control performance.

The utility model sterile type inhalation valve technological scheme is further set: described pedestal upper side is provided with the groove that is provided with ringwise, described air-breathing spring lower end places in the groove, described spheroid upper end is provided with convex annular wall, and described expiration spring lower end places protruding wall inboard.By setting like this, can effectively air-breathing spring be positioned in the pedestal groove, the expiration spring is positioned in the spheroid convex annular wall, thus more effective having prevented because spring is subjected to displacement the deviation that makes the elastic potential energy of the spring deviation and cause the storage tank internal air pressure.
The utility model sterile type inhalation valve technological scheme is further set: described cylindrical shell is fixedlyed connected with described pedestal sidewall by screw-thread fit.So be provided with, make that cylindrical shell and pedestal assembly and disassembly are convenient, when inhalation valve is unclean in the long-time use of process back, can takes inhalation valve apart cleaning easily, thereby improve the spatter property of inhalation valve.
The utility model sterile type inhalation valve technological scheme is simple in structure, and disassembly, cleaning are convenient, and further have the good advantage of pressure adjusting function.
