Abstract

The utility model discloses a straight-through antibiosis valve which comprises a valve body, a valve deck installed on the upper portion of the valve body and a support connected with the valve deck through an installation bolt. A middle head gasket is fixedly arranged in the connecting position of the support and the valve deck, a valve rod penetrates through the support and the valve deck and is connected with a valve element, the valve rod is connected with the support in a threaded mode, the valve element moves along with the valve rod so that an antibiosis valve flow channel can be opened or closed, sealing packing is arranged around the sliding connecting position of the valve rod and the support, and a sealing gasket is arranged in the contact position of the valve element and the antibiosis valve flow channel. According to the straight-through antibiosis valve, threads of the valve rod are not in contact with material liquid; the flow channel is of a streamlined shape so that the pressure loss can be small; the sealing gasket is replaceable so that disassembly can be convenient and the maintenance cost can be low. The sealing gasket, the middle head gasket and the sealing packing are all made of polytetrafluoroethylene, so that the straight-through antibiosis valve is long in service life, resistant to corrosion and capable of guaranteeing that inside and outside leakage is avoided.

Description

A kind of straight-through antibiotic valve
Technical field
The utility model relates to a kind of valve body, is specifically related to a kind of straight-through antibiotic valve.
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 a kind of straight-through antibiotic valve, adopts fairshaped runner, without dead angle, makes the pressure loss little.Seal ring in valve body, stem packing all adopts the high-quality polytetrafluoroethylmaterial material, guarantees without inside and outside leakage, corrosion-resistant, long service life.Sealing gasket is replaceable, dismantles more conveniently, and maintenance cost is low.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of straight-through antibiotic valve 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 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, and described connection handle is U-shaped.
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 structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
