Description
Technical field
The utility model belongs to pump valve field of mechanical technique, and in particular to a kind of helixseal formula stop valve.
Background technology
Stop valve is one of most popular valve, because the frictional force between sealing surface during opening and closing is small, is compared
It is durable, it is adapted to mesolow or high pressure valve, cardinal principle is, by valve rod pressure, valve clack sealing surface is closely pasted with breaking-out sealing surface
Close, prevent flow of media, in the prior art in order to improve the sealing effectiveness of stop valve, it will usually in flowing hole with respect to the one of flap
Antifriction metal (AFM) layer is welded on face edge, the antifriction metal (AFM) coordinated with it of being burn-on in flap relevant position passes through the knot of antifriction metal (AFM)
Close and improve sealing effectiveness, but the sealing means in this mode belong to pressing sealing, are concentric fits, in assembling and processing
Claimed accuracy is higher, if not reaching standard, drainage easily occurs, to problem above, Application No.
201521003145.3 patent is proposed by setting sealing station to improve sealing effectiveness in flowing hole, because sealing station front end is
Flexible structure, sealing station in extrusion process, easily damages flexible structure into sealing ring, influences sealing effectiveness, utilizes rotation stop
Bolt is mortgaged onto valve neck, improves the frictional force between rotation stop bolt and valve neck, so that the rotation stop effect of handwheel is improved, but by scheming
In understand, during rotation stop bolt rotation stop require in the relevant position of valve neck, position when being stopped to handwheel is required, and is sealed
Platform front end is flexible structure, and the position that handwheel is stopped during sealing is not known, it is therefore also possible to which its rotation stop can be influenceed.
Utility model content
The purpose of this utility model is that there is provided a kind of helixseal formula stop valve for existing issue.
The utility model is achieved through the following technical solutions：A kind of helixseal formula stop valve, including valve body, valve body
Including inlet channel and outlet conduit, flowing hole is provided between inlet channel and outlet conduit, interposition is installed in valve body
There is the valve rod spun with it by screw thread, valve rod bottom is provided with flap, and flap bottom is provided with external screw thread, and flowing hole internal upper part is provided with
The internal thread matched with external screw thread on flap, the internal thread bottom of flowing hole is provided with the annular type glue of installing in groove one, groove one
Pad, the bottom of groove one correspondence centre position is provided with installing pressure sensor in groove two, groove two, and valve stem top is provided with rotation hand
Wheel, provided with the valve neck being connected with valve body below rotation hand wheel, valve neck side is provided with the through hole vertical with valve rod, through hole and is provided with
Positioning screw.
As further improvement of these options, the cross section of the flowing hole is arc type structure, its further groove one
In the bending being recessed to the left, on the right for bending to the right be located on the vertical center line of groove one.
As further improvement of these options, the rotation hand wheel by controlling or gathering information using sensor manually
Electronic control.
The utility model has advantages below compared with prior art：By spirally setting valve rod, make valve rod in valve body
Spiral is set, and is then set external screw thread in flap bottom periphery, match with the internal thread in flowing hole, using ring-shaped rubber pad and
Stem bottom periphery is pressurizeed, raising sealing effectiveness, ring-shaped rubber pad convenient disassembly in groove one, it is possible to increase maintenance efficiency,
Pressure sensor is set in ring-shaped rubber pad bottom, will can be used for controlling opening for handwheel after the incoming control device of the information of harvesting
Stop；In valve neck side, wall sets positioning screw, and the friction using screw rod bottom surface and valve rod side positions it, can not stopped by handwheel
The limitation that stop bit is put, applicability is wider, compared with prior art, and operation more facilitates, easily maintenance, sealing reinforcement and not rapid wear
Service life that is bad, can extending at sealing.
