Embodiment Construction

[0019] Such as figure 1 , figure 2 The antibiotic stop valve shown includes a valve body 1, a valve cover 2, a valve disc 3 and a valve stem 4 with a linkage valve disc 3. The valve body 1 is provided with a medium inlet channel 11 and a medium outflow channel 12. The medium The connection between the inlet channel 11 and the medium outflow channel 12 is conducted through the connecting channel 13, and the sealing or separation of the valve disc 3 and the sealing seat 131 at the connecting channel 13 constitutes the sealing or communication between the medium inlet channel 11 and the medium outflow channel 12 (when the valve When the flap 3 is attached to the sealing seat 131, the connecting channel 13 is closed, and at this time, the medium inlet channel 11 and the medium outflow channel 12 cannot be conducted; when the valve disc 3 is separated from the sealing seat 131, the connecting channel 13 is connected. At this time, the medium inlet channel 11 and the medium outflo...

Abstract

The invention relates to a valve, in particular to an antibiotic stop valve which is used in medicinal biochemistry field and takes antibiotic as medium. The invention provides the following technical scheme: an antibiotic stop valve comprises a valve body, a valve cap, a valve clack and a valve rod linked with the valve clack; wherein the valve cap is internally provided with a valve rod moving space which is vertically arranged to the connecting passage on the valve body, the valve clack comprises a coupling end and a sealed end, the coupling end thereof is extended into the moving space on the valve cap and is connected with the valve, the sealed end is arranged in the connecting passage and is arranged toward a sealing socket, a sealing assembly which forms sealing between the moving space and the connecting passage is arranged between the moving space of the valve cap and the connecting passage of the valve body, the sealing assembly is arranged between the coupling end and the sealed end of the valve clack, and the sealing assembly comprises a plurality of seal rings. By adopting the technical scheme, an antibiotic stop valve with easy assembly, simple structure, sterile source and low cost is provided.

Description

technical field [0001] The invention relates to a valve, in particular to an antibiotic cut-off valve used in the field of medical biochemistry with antibiotics as the medium. Background technique [0002] Antibiotic valves are mainly used in the field of medicine, biochemical industry, and have high requirements for the control of bacterial infection rate during use. [0003] At present, the antibiotic valves appearing on the market and materials are mainly composed of valve body, valve cover, valve disc and valve stem of the linkage valve disc. The valve body is provided with a medium inlet channel and a medium outflow channel. The sealing or separation of the valve disc and the sealing seat at the connecting channel constitutes the sealing or conducting of the medium inlet channel and the medium outflow channel; usually, the connection between the valve cover and the valve body is equipped with a valve stem to pass through. The movable space of the valve stem passes thro...
