Description
Technical field
The utility model belongs to technical field of sealing technology, and in particular to one kind is without dead angle valve element.
Background technology
In fields such as food, pharmacy, for sterilizing the demand such as antibacterial, it is desirable to the inside of stop valve can accomplish no dead angle,
Remained without hydrops.But in the prior art, for the purpose of compensation mismachining tolerance, cut-off valve core is with valve rod typically using work
Dynamic connection, such as it is threadedly coupled or links up with connection.Although this connected mode can guarantee that sealing property, but a large amount of dead angles be present, hold
Easy hydrops, is not suitable for the field of food pharmaceutical, and valve element is done with valve rod it is integral, although as shown in Fig. 2 can eliminate
Dead angle, but mismachining tolerance can not be compensated, therefore it is very high to the requirement on machining accuracy of stop valve, processing, assembly precision are slightly worse, will
Cause valve leak.
Therefore it provides a kind of cut-off valve core at no dead angle, and mismachining tolerance can be compensated, become those skilled in the art
Urgent problem to be solved.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of without dead angle valve element, solution cut-off work in the prior art
The problem of a large amount of dead angles, valve element and the valve rod of integral type can not compensate mismachining tolerance be present with valve rod in the valve element of dynamic connection.
To achieve the above object, the technical solution adopted in the utility model is as follows：
One kind offers the installation for installing valve rod without dead angle valve element, including insert body, insert body center of top
Groove, insert body are detachably connected by mounting groove and valve rod lower end, and being provided with a circle around mounting groove at the top of insert body protects
Circle, valve rod bottom are arranged with a bellows, and top and the valve rod outer wall of bellows weld, the bottom of bellows and insert body
Top surface welding.
Further, the welding position of bellows and insert body is in the inner side of guard ring.
Further, the internal thread of mutual cooperation and outer spiral shell are respectively equipped with the inwall of mounting groove and the outer wall of valve rod lower end
Line, insert body and valve rod are detachably connected by screw thread.
Further, valve rod lower end is circumferentially with a circle projection, and projection and valve rod lower end be integral type structure, mounting groove and
Valve rod lower end is engaged, and valve rod lower end is detachably mounted by projection with insert body.
Compared with prior art, the utility model has the advantages that：
The utility model is simple in construction, and design science is reasonable, no dead angle, and can compensate mismachining tolerance, be extremely suitable for food,
The fields such as pharmacy use.
The utility model welds by the way that bellows-sheathed is located at into valve rod bottom, and by its top with valve rod outer wall, bottom with
The top surface welding of insert body, eliminates valve element and is connected the dead angles such as the fine crack to be formed, screw thread with valve rod, and liquid is in gravity during sealing
Can be flowed away completely under effect, in the absence of hydrops problem, will not the harmful substance such as breed bacteria, food and medicine can be effectively ensured
It is safe and healthy.
Bellows of the present utility model has certain elastic deformation, can compensate mismachining tolerance by deforming, ensure close
Seal effect.
