The present invention has the advantages that the setting of scraper, has the adhesive that can strike off ball seal face, it is ensured that ball seal
Face keeps cleaning, prevents ball seal surface damage, has cleaning valve clack sealing surface, does not allow to be also easy to produce leakage, is with long service life
The advantages of；The setting of conversion sleeve has the advantages that ensure that the direction of rotation of scraper is opposite with the direction of rotation of V-type sphere.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of V-type ball valve of the present invention.
Specific embodiment
As can be seen from FIG. 1, a kind of V-type ball valve, comprising: valve body 1, valve seat 2, V-type sphere 3, valve deck 5, bracket 7, valve rod
4, filler 9, gland 8 and driving device 6, valve deck 5 are fixed at 1 middle part upper end of valve body, and 5 upper end of valve deck is equipped with packing groove, pressure
Lid 8 is mounted on above packing groove, and filler 9 is glanded 8 and is fixedly installed at packing groove, and 7 lower end of bracket is fixedly connected with valve deck 5,
Driving device 6 is fixed at 7 upper end of bracket, and V-type sphere 3 is integrally placed at 1 inner cavity of valve body, and 3 outer surface of V-type sphere is equipped with spherical shape
Valve clack sealing surface, 4 upper end of valve rod connect with driving device 6, and 4 lower end of valve rod is passed down through bracket 7, gland 8, filler 9, valve deck
5 and V-type sphere 3 after protrude into 1 inner cavity lower part of valve body, for the setting of valve seat 2 in 1 inner cavity of valve body, valve seat 2 is equipped with can be with valve clack sealing surface shape
It at the sealing surface of seat of sealing, rotates V-type sphere 3 and matches to be formed with valve seat 2 and open or close valve, which also wraps
Include scraper 10 and conversion sleeve 11, the scraper 10 is placed in 1 inner cavity of valve body and is arranged outside V-type sphere 3, the scraper 10 be equipped with
Valve clack sealing surface can strike off the arc-shaped blade of valve clack sealing surface surface dielectric, 10 upper end of scraper and the formation of valve rod 4 after matching
Keyed connection, 10 lower part of scraper are equipped with locating ring, and locating ring protrudes into 1 lower end of valve body and matched on limitation scraper 10 with valve body 1
Lower movement, the V-type sphere 3 are also fixed with positioning sleeve, and the positioning sleeve is at circular pipe type structure and covers at 4 outer circle of valve rod,
It is equipped at the positioning sleeve using 4 axis of valve rod as the spiral groove of center line, the setting of conversion sleeve 11 turns in positioning sleeve lower part
It changes 11 tops of set and is equipped with the locating rod for protruding into spiral groove, 11 inside of conversion sleeve is threadedly coupled with the formation of valve rod 4, conversion sleeve 11
Lower part is equipped with the straight-bar for protruding into 1 lower end of valve body and capable of preventing conversion sleeve 11 from rotating, and the gland 8 passes through standard fasteners and valve deck
5 upper ends form connection.
When valve is opened by closed state, if the valve using dielectric viscosity it is higher, be easy crystallization or easy coking or
When medium contains sundries, medium or sundries are easy to be bonded at valve clack sealing surface, rotate clockwise valve rod, scraper is together with valve rod
Equidirectional rotation, at this moment, due to being to be threadedly coupled between conversion sleeve and valve rod, in valve rod rotation, conversion sleeve is moved up,
Again because the locating rod on conversion sleeve top protrudes into spiral groove, when conversion sleeve and locating rod claim dynamic upwards, V-type ball
Body is rotated by center line of valve rod axis, and the direction of rotation of V-type sphere and scraper direction of rotation be on the contrary, for rotation counterclockwise,
Scraper strikes off the medium at flap sealing, while valve opening at this time.
Similarly, when valve is closed by open state, rotary valve rod counterclockwise, scraper rotates counterclockwise, while conversion sleeve
It is moved down with locating rod, V-type sphere is driven to rotate clockwise, scraper strikes off the medium at valve clack sealing surface, while valve closes
It closes.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
