Abstract
The utility model relates to an electronic aseptic stop valve of manual pneumatics, including valve body, valve gap, valve rod, bellows, there is the valve pocket in the valve body, valve rod one end is provided with the case, and this end is equipped with the bellows in stretching into the valve pocket on the valve rod, still include the diaphragm that is used for keeping apart valve gap and valve pocket, bellows top and diaphragm seal fixed connection, bellows bottom and the sealed fixed connection of case make and are kept apart totally by the seal structure that diaphragm, bellows and case enclosed between valve rod and the valve body. The utility model discloses the fluid can not be followed the interstitial flow and gone into the ripple intraduct, results in valve rod and bellows inner gap bacterial growing.
Description
Technical field
The utility model relates to a kind of stop valve, is the electronic aseptic stop valve of a kind of hand-operated pneumatic specifically.
Background technique
Stop valve, be one of most popular a kind of valve, why very popular it is, be due in opening and closing process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, is not only applicable to mesolow, and is applicable to high pressure.Stop valve can be divided into straight-through stop valve, Oblique Stop Valve, Angle Stop valves and plunger stop valve by channel direction.Current stop valve structure mainly comprises the seal bellows of handwheel, valve rod, valve gap, valve body, spool and spool outside, handwheel connects valve rod, is formed with valve pocket in valve body, and valve rod is connected with valve pocket inner spool through valve gap.Closed principle is, relies on valve thick stick pressure, spool and valve body are fitted tightly, and stops medium circulation.
There is following shortcoming in this stop valve: the first, and sealing is poor, has space between spool and bellows, and seal imperfection between valve rod and bellows, and fluid can enter bellows interior from the gap between spool and bellows, easy breed bacteria.The second, also have gap between bellows and the diaphragm on its top, fluid can enter bellows interior from the gap between diaphragm and bellows, easy breed bacteria.3rd, the sealing configuration performance of diaphragm and valve body is perfect not.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of hand-operated pneumatic electronic aseptic stop valve, the bellows top of stem exterior is fixedly connected with the diaphragm seal of valve body with isolation valve seat, be fixedly connected with seal spool bottom bellows, the structure that the outer fringe seal of diaphragm, bellows and spool is formed by connecting makes valve rod and valve body is completely isolated comes, fluid can not flow into bellows interior from gap, causes valve rod and bellows internal clearance dead angle bacteria breed.In addition, diaphragm adopts straight formula diaphragm, and valve body top is provided with straight formula seal groove, and the straight formula seal groove close contact of straight formula diaphragm and valve body, reaches sealing purpose.
To achieve these goals, the technical solution of the utility model is as follows:
The electronic aseptic stop valve of hand-operated pneumatic, comprise valve body, valve gap, valve rod, bellows, have valve pocket in valve body, valve rod one end is provided with spool, and this end stretches in valve pocket, valve rod is provided with bellows, it is characterized in that, also comprise the diaphragm of isolating valve gap and valve pocket, described bellows top is fixedly connected with diaphragm seal, be fixedly connected with seal spool bottom bellows, make between valve rod and valve body by diaphragm, bellows and spool the sealing configuration that surrounds is completely isolated comes.
The concrete Placement that described bellows top and diaphragm seal are fixedly connected with is for welding.
The concrete Placement be fixedly connected with seal spool bottom described bellows is for welding.
Described diaphragm is straight formula diaphragm, and valve body top is provided with straight formula seal groove, and the straight formula seal groove close contact of straight formula diaphragm and valve body, reaches sealing purpose.
Described diaphragm is the trapezoidal diaphragm of bottom with angle of inclination, and valve body top is provided with trapezoidal seal groove, and the trapezoidal seal groove close contact of trapezoidal diaphragm and valve body, reaches sealing purpose.
Described diaphragm is arc diaphragm, and valve body top is provided with arc seal groove, and the arc seal groove close contact of arc diaphragm and valve body, reaches sealing purpose.
Also comprise teflon gasket, teflon gasket is located at bottom spool, is bolted to connection on spool.
Described valve body is straight-through type valve body or angie type valve body.
Also comprise handwheel, handwheel is arranged on valve stem top.Described handwheel can replace to rotary pneumatic final controlling element or electronic many revolution final controlling element regulate to replace handwheel handmade rotary, the rotary actuator of Pneumatic/electric adopts the pneumatic or electronic master control system that coordinates to complete adjustment automatically or cut-off novel asepsis diaphragm shutoff valve, and automaticity is high.
Adopt arc transition between described valve pocket inwall and inclined-plane, without dead angle design, ensure that valve pocket can not material stock, liquid fluidity is good.
The utility model has the advantages that: the bellows top of stem exterior is fixedly connected with the diaphragm seal of valve body with isolation valve seat, be fixedly connected with seal spool bottom bellows, the structure that the outer fringe seal of diaphragm, bellows and spool is formed by connecting makes valve rod and valve body is completely isolated comes, fluid can not flow into bellows interior from gap, causes valve rod and bellows internal clearance dead angle bacteria breed.
