Abstract
The utility model discloses a three-channel antibiotics valve, which comprises a valve body, a valve cover, a valve rod, a valve clack and a valve rod driving mechanism, the valve body is provided with an inlet cavity and an outlet cavity, a communicating hole which is horizontal and matched with the valve clack is arranged between the inlet cavity and the outlet cavity, one side of the inlet cavity of the valve body is integrally provided with three fluid channels, and an O-seal ring is arranged between the valve cover and the valve rod. The utility model has the advantages of convenient switching, good tightness and stable and reliable running.
Description
Technical field
The utility model relates to a kind of threeway antibiotics valve.
Background technique
The valve that the special process of industries such as biofermentation, medicine, fine chemistry industry, medical bioengineering requires on this technology, to use need satisfy do not leak, not microbiological contamination, performance such as tank switching not, otherwise will cause the production bacterium source of valve applications enterprise to pollute and a large amount of wastes of material.In prior biological medicine fermenting and producing; Seeding tank divides the adapted valve often all to adopt stop valve, ball valve, membrane valve, be welded to form with pipe fitting; So a plurality of valves not only take up room on same pipeline, more than on the pipeline dead angle and leakage point, increase the frequent blending operation of workman in addition; Time-consuming, the waste device resource.The applicant has has formerly researched and developed a kind of three-channel antibiotics valve that has for this reason, thereby needs to arrange that to solve tradition a plurality of valves bring the problem that the dead angle is many on the pipeline, leakage point is many.But the packing seal that it adopts, the application inventor finds that in follow-up research and development packing seal switch resistance is bigger, is unfavorable for operation.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and provides a kind of switch convenient, a kind of three-passage antibiotic valve of good airproof performance, stable and reliable operation.
For realizing above-mentioned purpose; The technological scheme of the utility model is to include valve body, valve gap, valve rod, flap and valve rod driving mechanism; Said valve body is provided with snout cavity and outlet plenum; Be provided with between snout cavity and the outlet plenum level and with the suitable connecting port of flap, snout cavity one side of described valve body has been wholely set three fluid passages, is provided with O-ring seals between described valve gap and the valve rod.Through this setting, adopt 0 shape seal ring to replace packing seal, open and close are more free and relaxed like this, and good seal performance, stable equipment operation.
Further being provided with is that described valve rod includes upper valve rod and lower valve rod, detachably is fixedly connected through clamp ring between this upper valve rod and the lower valve rod.Through this setting, valve inner does not have other and connects internals, therefore can reach no dead angle, no microbiological contamination source, and outside coupling is a clamp ring, therefore is easy to installation, care and maintenance.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation.
Embodiment
The embodiment of the utility model as shown in Figure 1; Include valve body 1, valve gap 2, valve rod 3, flap 4 and valve rod driving mechanism; The described valve rod driving mechanism of present embodiment is preferably handwheel 6, and this handwheel 6 is linked with valve rod 3, constitutes the driving to valve rod; Said valve body 1 is provided with snout cavity 11 and outlet plenum 12; Be provided with between snout cavity 11 and the outlet plenum 12 level and with the suitable connecting port 13 of flap, snout cavity 11 1 sides of described valve body 1 have been wholely set three fluid passages 14, are provided with O-ring seals 5 between described valve gap 2 and the valve rod 3.In addition; The described valve rod 3 of present embodiment includes upper valve rod 31 and lower valve rod 32, detachably is fixedly connected through clamp ring 33 between this upper valve rod 31 and the lower valve rod 32, and so valve inner does not have other connection internals; Therefore can reach no dead angle; No microbiological contamination source, outside coupling are a clamp ring, therefore are easy to installation, care and maintenance.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
