Description

Antibiotic stop valve

Technical field

The present invention relates to a kind of shut-off valves, more particularly to a kind of using antibiotic as the antibiotic stop valve of medium.

Background technique

Shut-off valve refers to that the valve that opening and closing element (flap) is moved along valve seat center line, flap do straight line along the center line of valve seat Movement since to open or close stroke relatively short for the valve rod of such valve, and has very reliable cutting function, and by In the variation of valve seat port and the stroke proportional of flap, it is very suitable for the adjusting to flow.

Antibiotic stop valve is the shut-off valve for being mainly used in biofermentation, medicine and other fields, is mainly to be situated between with antibiotic Matter leads to product microbiological contamination in order to avoid antibiotic medium residual, therefore needs often to all parts that can contact antibiotic medium It cleaned, killed virus.

Existing antibiotic stop valve cleaning and sterilization is difficult, and cleaning effect is poor, and medium is caused to remain, product microbiological contamination.

Summary of the invention

In order to overcome the shortcomings of that background technique, the present invention provide a kind of antibiotic stop valve, existing antibiotic cut-off is solved The problem of valve cleaning and sterilization is difficult, and cleaning effect is poor, and medium is caused to remain, product microbiological contamination.

The technical solution adopted in the present invention: a kind of antibiotic stop valve, including valve body, flap, valve rod, valve deck, it is described Valve body includes that medium enters channel, lumen, medium flow pass, and it includes that horizontal straight-through import is logical that the medium, which enters channel, Road, the vertical channel for being arranged vertically and being connected to lumen；The medium flow pass includes horizontal straight-through exit passageway, inclination Arrange the access ramp being connected to lumen；The terminal bottom of the intake channel is arranged the first sewage draining exit, before the exit passageway Hold bottom that the second sewage draining exit is set.

The intake channel diameter is greater than vertical channel diameter.

Pass through arc-shaped transition between the intake channel and vertical channel；The arc-shaped design of ramp way.

The flap includes flap ontology, and flap ontology one end is equipped with the mounting groove for cooperating with valve rod, another Sealing element is arranged in end, is additionally provided with the cleaning hole that two radial directions lead to mounting groove on the flap ontology.

The cleaning outer end of hole mouth is in horn-like.

The valve rod and the arc-shaped structure in one end of flap cooperation design.

Flap body end center is equipped with threaded rod, and the sealing element is set on threaded rod, and with flap ontology End face fitting；The sealing element is locked by fixture nut, and elastomeric pad is equipped between the sealing element and fixture nut.

Flat pad is equipped between the elastomeric pad and sealing element.

It is wholely set on the end face of flap ontology one end and encloses protective case around sealing element one.

The beneficial effects of the present invention are: using above scheme, it is easier to it cleans, and without dead angle, medium is effectively prevent to be detained, Avoid product microbiological contamination.

Specific embodiment

Embodiments of the present invention is further illustrated with reference to the accompanying drawing:

As shown in Figs. 1-2, a kind of antibiotic stop valve, including valve body 1, flap 2, valve rod 3, valve deck 4, the valve body 1 wrap It includes medium and enters channel 11, lumen 12, medium flow pass 13, it includes that horizontal straight-through import is logical that the medium, which enters channel 11, Road 111, the vertical channel 112 for being arranged vertically and being connected to lumen 12；The medium flow pass 13, which includes that level is straight-through, to be gone out Mouth channel 131, be in tilted layout the access ramp 132 being connected to lumen 12；First row is arranged in the terminal bottom of the intake channel 111 The second sewage draining exit 15 is arranged in the front bottom end of dirty mouth 14, the exit passageway 131.

Intake channel 111, exit passageway 131 use horizontal put-through channel, not only more convenient processing, but also put-through channel It is more advantageous to sterilization, detoxicating, medium is prevented to be detained certain.

In addition, the first sewage draining exit 14, the second sewage draining exit 15 are respectively at intake channel 111,131 bottom of exit passageway, place It, can be more effectively by the residual medium in valve channel from the first sewage draining exit 14 when being cleaned in same low-level position Or second sewage draining exit 15 be discharged, cleaning effect is more preferable.

And the first sewage draining exit 14 is arranged in the terminal of intake channel 111, exit passageway is arranged in the second sewage draining exit 15 Leading portion, can take multiple valves, and disjunction cleaning can greatly reduce wash number, reduce the wasting of resources.

As shown in Fig. 2, 111 diameter of intake channel is greater than 112 diameter of vertical channel, closed-entry design can be more Be conducive to media flow.

As shown in Fig. 2, passing through arc-shaped transition between the intake channel 111 and vertical channel 112；The ramp way 32 Arc-shaped design, the structure design of arc can medium spurt into the intracorporal all directions of valve to keep pressure consistent, medium flow field It is logical more steady, the impact to flap is reduced, the service life of flap is greatly prolonged, while in cleaning, guaranteeing valve inner Without dead angle, it is more advantageous to valve body cleaning, avoids product microbiological contamination.

As shown in Figure 3-4, the flap 2 include flap ontology 21, described 21 one end of flap ontology be equipped with for valve rod 3 The mounting groove 211 of cooperation, the other end are arranged sealing element 22, are additionally provided with two radial directions on the flap ontology 21 and lead to mounting groove 211 cleaning hole 212.

It regard one of cleaning hole 212 as high-pressure water inlet hole, another cleaning hole 212 is used as low level drain hole, uses V mouthfuls of water rifles of high pressure directly carry out jet cleaning, change conventional clean mode, without disassembly, not only clean it is more convenient, but also Cleaning effect is good, prevents product microbiological contamination.

Wherein, 212 external port of cleaning hole is designed to horn-like, when cleaning, is more convenient hydraulic giant insertion cleaning hole 12, side Just it cleans.

As shown in Fig. 1, Fig. 5, Fig. 6, the valve rod 3 is designed with the arc-shaped structure in one end that flap 2 cooperates, with V mouthfuls of water When rifle jet cleaning flap 2 and valve rod 3, the arcuate structure of 3 end of valve rod makes valve rod 3 without dead angle, is more advantageous to cleaning effect.

As shown in figure 3,21 end center of flap ontology is equipped with threaded rod 214, the sealing element 22 is set in screw thread On bar 214, and it is bonded with 21 end face of flap ontology；The sealing element 22 is locked by fixture nut 24, the sealing element Elastomeric pad 23 is equipped between 22 and fixture nut 24.

Using elastomeric pad 23, spring energy guarantees that fixture nut 24 will not accidentally slip out after the nut 24 that is locked, Ensure non-internal leakage, is used compared with threaded rod 214 punches and is inserted into alignment pin with the prior art, installation and removal are more square Just.

Further, it is equipped with flat pad 25 between the elastomeric pad 23 and sealing element 22, increases and sealing element 22 Contact area guarantees that sealing element is fixed and is unlikely to deform.

Protective case 213 is enclosed around sealing element 22 1 as shown, being wholely set on the end face of described 21 one end of flap ontology, The protective case 213 reduce medium washing away to sealing element 22, guarantee will not deformation failure, improve sealing element 22 service life.

In addition, the above-mentioned sealing element 22 referred to uses polytetrafluoroethylsealed sealed pad, there is the etch-proof effect of preferable high temperature high voltage resistant Fruit can guarantee sealing effect.

Embodiment is not construed as the limitation to invention, but any based on spiritual improvements introduced of the invention, all Ying Ben Within the protection scope of invention.
