摘要： Disclosed is a medical oxygen mixing valve comprising a valve body, a valve cap, a spring, spool assembly, dial assembly and knob assembly. An axial hole is set inside the valve body. The spool components capable of sliding in an axial direction along the wall of the hole are set in the hole. An air input hole, oxygen input hole and gas mixture output hole which are in communication with the hole are set in the radial direction of the valve body. The knob components are used for adjusting the position of the spool components in the hole set in the axial direction of the valve body to adjust the sizes of the air input hole and oxygen input hole blocked by the spool components, thereby adjusting the output of the oxygen concentration. The oxygen mixing valve has the advantages of a simple structure, and easy machining, installation and debugging.

摘要： A bypass device for an absorption tank comprises a two-position three-way valve, a micro switch, a control circuit board, and a micro switch actuation mechanism. When an absorption tank needs to be replaced, in the process of rotating a handle, a contact wheel of the micro switch is pressed to send an electrical signal to the control circuit board, and the control circuit board controls a solenoid valve, thereby controlling a gas path of the two-position three-way valve, and bypassing the absorption tank effectively and timely. After the absorption tank is replaced, it is only required to rotate the handle to the original position, so that the entire replacement process involves simple operations and is effective, and the sealing effect of the gas path is desirable.
