Abstract
The utility model discloses a three-way antimicrobial valve which comprises a valve body, a valve hood installed on the upper portion of the valve body and a support connected with the valve hood through an installation bolt, a middle headrest is fixedly arranged on the joint between the support and the valve hood, a valve rod penetrates through the support and the valve hood and is connected with a valve element, the valve rod is in thread connection with the support, the valve element moves along with the valve rod to open or close an antimicrobial valve circulation channel, sealing filler is arranged on the sliding joint between the valve rod and the support in a surrounding mode, and a sealing pad is arranged on a contact position between the valve element and the antimicrobial valve circulation channel. According to the three-way antimicrobial valve, threads of the valve rod do not make contact with feed liquid; the streamlined channel enables pressure loss to be little; the sealing pad can be replaced and is more convenient to disassemble and low in maintenance cost. The sealing pad, the middle headrest and the sealing filler are all made of polytetrafluoroethylene materials. The three-way antimicrobial valve is low in service life and resistant to corrosion, and guarantees non inside and outside leakage.
Description
Technical field
The utility model relates to a kind of valve body, is specifically related to the antibiotic valve of a kind of threeway.
Background technique
Antibiotic valve is mainly used in the material, water, vapour of biofermentation, medicine and beer fermentation, amino acid fermentation, biological pesticide fermentation, bio-feritlizer fermentation, various antibiotic fermentation, biology, biochemistry, chemical pharmacy, the cold fields such as control.Antibiotic valve has stronger sterilization, detoxicating can prevent the product microbiological contamination, improves constantly the fermentation recovery rate of applying unit and the economic benefit of enterprise.
Existing antibiotic valve seal is bad, easily from the leakage of screw mandrel joint, and contaminated material not only, and easily corrode screw mandrel, working life is short.
The model utility content
The technical problems to be solved in the utility model is to provide the antibiotic valve of a kind of threeway, reasonable in design, without dead angle, can effectively reduce the microbiological contamination rate in pharmaceutical manufacturing, for the antibiotics sterile production provides reliable assurance; Good seal performance, stopped run, drip, leak, saved energy consumption; Material is reliable, it is meticulous, durable in use to make, and sealing adopts teflon, and decay resistance is strong.
For achieving the above object, the technical solution of the utility model is as follows:
The antibiotic valve of a kind of threeway comprises:
One valve body,
One is arranged on the valve gap on valve body top,
One connects the support of valve gap by construction bolt, and described support and valve gap joint are fixedly installed the headrest in,
Valve rod runs through support and valve gap connects a spool, and described spool arranges three circulation passage intersections, and valve rod is threaded with support, and described spool is followed stem movement, opens or closes antibiotic valve circulation passage,
Described valve rod and the support place of being slidably connected are surrounded with stuffing box packing, and spool and antibiotic valve circulation passage contacting point arrange a sealing gasket.
In a preferred embodiment of the present utility model, the valve rod end connects a handwheel.
In a preferred embodiment of the present utility model, described support upper end, be symmetrically arranged with a connection handle near the valve rod end.
In a preferred embodiment of the present utility model, also comprise that one arranges the petcock of valve body downside, regularly open petcock, the dirt in discharge route.
In a preferred embodiment of the present utility model, described sealing gasket, the middle headrest and stuffing box packing all adopt polytetrafluoroethylmaterial material to be made.
By technique scheme, the beneficial effects of the utility model are:
The utility model threaded stem does not contact with feed liquid; Fairshaped runner, make the pressure loss little; Sealing gasket is replaceable, dismantles more conveniently, and maintenance cost is low.
And sealing gasket, the middle headrest and stuffing box packing all adopt polytetrafluoroethylmaterial material to be made.Life-span is long, corrosion-resistant, guarantees to leak outside in nothing.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is sectional view of the present utility model.
Fig. 2 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
See figures.1.and.2, the antibiotic valve of a kind of threeway comprises:
One valve body 2,
One is arranged on the valve gap 11 on valve body 2 tops,
One by the support 7 of construction bolt 8 connection valve gaps 11, and described support 7 is fixedly installed the headrest 6 in valve gap 11 joints,
Valve rod 5 runs through support 7 and valve gap 11 connects a spool 4, and described spool arranges three circulation passage intersections, and valve rod 5 is threaded with support 7, and described spool 4 is followed valve rod 5 motions, opens or closes antibiotic valve circulation passage,
Described valve rod 4 is surrounded with stuffing box packing 9 with support 7 places of being slidably connected, and spool 4 arranges a sealing gasket 3 with antibiotic valve circulation passage contacting point.
In a preferred embodiment of the present utility model, valve rod 5 ends connect a handwheel 10.
In a preferred embodiment of the present utility model, described support 7 upper ends, be symmetrically arranged with a connection handle 12 near valve rod 5 ends.
