Abstract

The utility model relates to a bacteriophage disconnecting valve employing antibiotic as medium used in the biological and chemical pharmacy field, comprising a valve body, a valve cover, a valve rod connected with the valve cover through the screw at the middle of the cover, a flapper at the downside of the valve rod connected with the cavity of the valve body, fillings in the top of the valve rod, a pressing cover on the fillings and a handwheel fixed on the upside of the valve rod outside the valve body. The valve body's import directional through channel A has a horizontal beeline type. The output directional through channel B has an inclined beeline type. Upper extreme C of the flapper has a cone angle type. The lower end surface E of the valve cover also has a cone angle type. The joint D between the valve body and the valve cover has a tenon slot type. The utility model has compact conformation, artistic exterior, superior sealing property, long performance life, fluent inner cavity and entire through channel in the valve body, no adhesives, and no dead angle, therefore, the chances of bacterium infecting the valve are reduced greatly and the quality of the antibiotic spicery is guarantied, thereby the utility model has the value for spreading and using.

Description

The antibiotic stop valve

Technical field

The utility model relates to a kind of pipeline valve, specifically is that a kind of being used in the biology, chemical pharmacy field with the antibiotics is the antibiotic stop valve of medium.

Background technique

The antibiotic stop valve is to use in biochemistry pharmacy special dimension, so it in use controls the requirement with strictness to the microbiological contamination rate.But present existing antibiotic stop valve does not design at the antibiotic technological requirement specially, and mostly be to adopt traditional common stop valve to substitute, only flap valve is done to change and increase a soft seal pad to form slightly, therefore often exist following defective: 1, because of valve body latus rectum runner is curved type, the inboard can not be polished, and water passage surface is rough, cause media flow not smooth, easily produce sizing, the dead angle is arranged, cause local infection, make the microbiological contamination rate rise; 2, general prominent face structure is adopted in liner soft seal sheet joint between valve body and the valve gap, easily produces the cold flow phenomenon, causes leakage; 3, fixedly flap valve soft seal pad adopts the through hole hexagon nut, so outstanding outside thread still exposes outside on the flap valve, it will make the medium residual flow wherein easily, causes infection, and the soft seal pad is common Tetrafluoro spacer, so working life is short, changes frequent; 4, valve gap is the rising stem (RS.) structure, and the threaded stem position is exposed for a long time, easily gets rusty, and adopts traditional filling-material structure, and poor sealing performance is prone to " run, emit, leak " phenomenon, and changes very inconvenience of filler.

The model utility content

The purpose of this utility model be to overcome the defective that prior art exists and provide a kind of compact structure, aesthetic in appearance, medium is smooth, the microbiological contamination rate is low, the antibiotic stop valve of good seal performance, long service life.

The purpose of this utility model realizes by following technological scheme: a kind of antibiotic stop valve, comprise by valve body, valve gap, pass and be connected the endoceliac flap valve of valve, valve rod top filler, filler gland and valve body outer fixing with its valve rod that is threaded, valve rod lower end in the middle of the valve gap and constitute at the handwheel on the valve rod, its described valve body import, exports to latus rectum runner B to being the tilt angle straight line type for being the straight horizontal line style to latus rectum runner A; Described flap valve upper-end surface C is for being the cone angle type; Described valve gap lower end surface E is for being the cone angle type; Described valve body and valve gap joint D are for being the tongue-and-groove type.

The utility model antibiotic stop valve is fixed with special soft seal pad by the blind hole hexagon nut on the wherein said flap valve lower end surface

The utility model antibiotic stop valve is lined with the soft seal pad between wherein said valve body and the valve gap joint D.

The utility model antibiotic stop valve, wherein said blind hole hexagon nut lower end surface is tapered.

Antibiotic stop valve of the present utility model, wherein said valve gap is for being half rising stem (RS.) type, and the threaded stem position is enclosed in the valve gap.

Antibiotic stop valve of the present utility model is provided with the O RunddichtringO between wherein said valve rod middle part and the valve gap.

The utility model adopts technique scheme, its valve body latus rectum is imported and exported to runner type linearly, the surface is smooth through polishing, again because of valve gap lower end surface and flap valve upper-end surface for being the cone angle type, and on the flap valve lower end surface fixedly the soft seal pad adopt the blind hole hexagon nut of taper, make medium smoothness in whole valve body latus rectum runner and the chamber, not sizing, no dead angle, reduce residual medium, greatly reduced the microbiological contamination rate of valve, guaranteed the quality of antibiotic spice.Be lined with special soft seal pad on the flap valve lower end surface, prolonged working life.The threaded stem position is enclosed in and is difficult in the valve gap getting rusty and packing seal is strong, it is convenient to change.The valve rod middle part is lined with O type circle, has prevented that medium is excessive.Adopt tongue-and-groove type structure between valve body and the valve gap joint and be lined with the soft seal pad, can prevent to produce cold flow and middle part and leak, so the utlity model has popularizing value.

Description of drawings

Fig. 1 is the utility model structure sectional view.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

As shown in Figure 1, a kind of antibiotic stop valve, comprise by valve body 1, valve gap 7, pass and be connected the endoceliac flap valve 3 of valve, valve rod top filler 8, filler gland 9 and valve body outer fixing with its valve rod that is threaded 4, valve rod lower end in the middle of the valve gap and constitute at the handwheel 10 on the valve rod, its valve body 1 import is designed to the straight horizontal line style to latus rectum runner A, outlet is designed to the tilt angle straight line type to latus rectum runner B, the smooth and sizing not of water passage surface runner after polishing.Its flap valve 3 upper-end surface C are designed to the cone angle type, valve gap 7 lower end surface E also are designed to the cone angle type, reach and adopt fixedly soft seal pad 2 of blind hole hexagon nut 11 on flap valve 3 lower end surfaces, make that whole valve body latus rectum runner is unimpeded, media flow is quick and smooth in the valve pocket, can not form the material dead angle, has reduced residual medium, greatly reduce the microbiological contamination rate of valve, guaranteed the quality of antibiotic spice.Valve body 1 is designed to tongue-and-groove type structure with valve gap 6 joint D, is lined with soft seal pad 6 between the D of joint simultaneously, and so tight chimeric connection and lining sealing gasket can prevent to produce cold flow and middle part and leak.Its blind hole hexagon nut 11 underparts are designed to taper, in the time of can reducing media flow resistance or when closing the underpart stop raffinate.Its valve gap 7 is designed to half rising stem (RS.) type, makes valve rod 4 screw thread positions be enclosed in the valve gap 7, and the screw thread position is difficult for getting rusty like this, and uses the strong filler of sealing, and it is convenient to change.Its soft seal pad 2 is for to be made by special material, and it has prolonged working life, has removed frequent replacing from.Between valve rod 4 middle parts and valve gap 7, be provided with O RunddichtringO 5, play sealing and prevent the effect that medium leaks.
