Further, the gland is attached to the upper end of the bonnet by standard fasteners.
The invention has the advantages that: the scraper is arranged, so that the adhesive on the sealing surface of the ball body can be scraped, the sealing surface of the ball body can be kept clean, the sealing surface of the ball body can be prevented from being damaged, and the scraper has the advantages of cleaning the sealing surface of the valve clack, being not easy to leak and having long service life; the arrangement of the conversion sleeve has the advantage of ensuring that the rotation direction of the scraper is opposite to the rotation direction of the V-shaped ball.
Drawings
Fig. 1 is a schematic structural diagram of a V-shaped ball valve according to the present invention.
Detailed Description
As can be seen from fig. 1, the V-shaped ball valve includes: the valve comprises a valve body 1, a valve seat 2, a V-shaped ball 3, a valve cover 5, a support 7, a valve rod 4, a packing 9, a gland 8 and a driving device 6, wherein the valve cover 5 is fixedly arranged at the upper end of the middle part of the valve body 1, the upper end of the valve cover 5 is provided with a packing groove, the gland 8 is arranged above the packing groove, the packing 9 is fixedly arranged at the packing groove by the gland 8, the lower end of the support 7 is fixedly connected with the valve cover 5, the driving device 6 is fixedly arranged at the upper end of the support 7, the V-shaped ball 3 is integrally arranged in the inner cavity of the valve body 1, the outer surface of the V-shaped ball 3 is provided with a spherical valve clack sealing surface, the upper end of the valve rod 4 is connected with the driving device 6, the lower end of the valve rod 4 downwards penetrates through the support 7, the gland 8, the packing 9, the valve cover 5 and the V-shaped ball 3 and, the valve also comprises a scraper 10 and a conversion sleeve 11, wherein the scraper 10 is arranged in the inner cavity of the valve body 1 and is arranged outside the V-shaped ball body 3, the scraper 10 is provided with an arc-shaped blade which can scrape a medium on the surface of the sealing surface of the valve clack after being matched with the sealing surface of the valve clack, the upper end of the scraper 10 is in key connection with the valve rod 4, the lower part of the scraper 10 is provided with a positioning ring, the positioning ring extends into the lower end of the valve body 1 and is matched with the valve body 1 to limit the scraper 10 to move up and down, the V-shaped ball body 3 is also fixedly provided with a positioning sleeve which is in a circular tube type structure and is sleeved at the outer circle part of the valve rod 4, a spiral groove which takes the axis of the valve rod 4 as the central line is arranged at the positioning sleeve, the conversion sleeve 11 is arranged at the lower part of the positioning sleeve, the upper part of the conversion sleeve 11, the gland 8 is connected to the upper end of the bonnet 5 by standard fasteners.
When the valve is opened from a closed state, if the valve uses a medium which is high in viscosity and easy to crystallize or coke or the medium contains impurities, the medium or the impurities are easy to adhere to the sealing surface of the valve clack, the valve rod is rotated clockwise, the scraper and the valve rod rotate together in the same direction, at the moment, because the conversion sleeve is in threaded connection with the valve rod, the conversion sleeve moves upwards when the valve rod rotates, and because the positioning rod on the upper part of the conversion sleeve extends into the spiral groove, when the conversion sleeve and the positioning rod are upwards weighed, the V-shaped ball rotates by taking the axis of the valve rod as a central line, the rotating direction of the V-shaped ball is opposite to that of the scraper and rotates anticlockwise, at the moment, the scraper scrapes the medium at the sealing position of the.
In a similar way, when the valve is closed by the opening state, the valve rod is rotated anticlockwise, the scraper rotates anticlockwise, the conversion sleeve and the positioning rod move downwards to drive the V-shaped ball body to rotate clockwise, the scraper scrapes a medium at the sealing surface of the valve clack, and the valve is closed simultaneously.
