Abstract
A hemispherical valve with valve core track is composed of spherical valve body, valve cover, valve shaft seat, spherical crankshaft between valve shaft seats, spherical valve core, valve body sealing ring at outlet in valve body, valve core sealing ring matched with valve body sealing ring, valve driver on valve cover, and roller on radial short shaft. The valve core is hinged on the spherical crankshaft, and the valve core rotates under the constraint of the circular arc track under the drive of the spherical crankshaft, so that the valve body sealing ring and the valve core sealing ring are less in abrasion during opening and closing, and the sealing pair can be matched after long-term use.
Description
Technical Field
The invention relates to a top-mounted half ball valve, in particular to a track of a spherical crown valve core of the top-mounted half ball valve and a connection between the spherical crown valve core and a spherical crankshaft.
Background
The upper-mounted half ball valve is provided with a spherical valve body, an outlet is arranged in front of the valve body, an inlet is arranged at the rear of the valve body, a valve cover is arranged above the valve body, valve shaft seats are respectively arranged below the upper cover and the valve body, a spherical crankshaft is arranged between the valve shaft seats, a spherical crown-shaped valve core is connected in the middle of the spherical crankshaft, a valve body sealing ring is arranged at the outlet in the valve body, a valve core sealing ring matched with the valve body sealing ring is arranged on the valve core, and a valve driving device connected with the upper end of the spherical crankshaft is arranged on the valve cover.
The driving device drives the spherical crankshaft to rotate along the valve shaft to drive the spherical crown valve core to rotate in the forward direction and the reverse direction along the valve shaft, so that the half ball valve is opened and closed.
In the prior art, the middle of the spherical crown-shaped valve core of the half ball valve is connected in the middle of the spherical crankshaft in a positioning manner and is of a cantilever structure, when the half ball valve is opened and closed, the abrasion of the valve body sealing ring and the valve core sealing ring is large, after a period of use, the valve core and the spherical crankshaft are connected loose, and the sealing pair cannot be matched for a long time after long-term use.
Disclosure of Invention
The invention aims to overcome the defects, and provides the half ball valve with the spool rail, which has the advantages that the abrasion of the valve body sealing ring and the spool sealing ring is small when the half ball valve is opened and closed, and the sealing pair can be matched with the spool rail after long-term use.
The invention is realized by the following method.
The hemispherical valve with valve core track has spherical valve body, outlet in front of the valve body, inlet in back of the valve body, valve cover above the valve body, valve shaft seat below the upper cover and the valve body, spherical crankshaft between the valve shaft seats, spherical crown valve core connected to the middle of the spherical crankshaft, valve body sealing ring in the outlet of the valve body, valve core sealing ring matched with the valve body sealing ring, valve driving device connected to the upper end of the spherical crankshaft on the valve cover,
the middle of the valve core is hinged in the middle of the spherical crankshaft, the upper and lower parts of the outer circumference of the valve core are provided with radial short shafts, the radial short shafts are provided with rollers, and a section of circular arc-shaped track which is perpendicular to the valve shaft and matched with the rollers is arranged below the valve cover and below the valve body respectively.
The middle of the valve core is hinged in the middle of the spherical crankshaft, the upper part and the lower part of the outer circumference of the valve core are provided with radial short shafts, the radial short shafts are provided with rollers, and a section of circular arc-shaped track which is perpendicular to the valve shaft and matched with the rollers is arranged on the plane below the valve cover and below the valve body. When the spherical valve is used, the driving device drives the spherical crankshaft to rotate forwards and reversely along the valve shaft, and the spherical crown valve core can be driven to rotate forwards and reversely along the valve shaft under the constraint of the circular arc track. When the valve is opened, the driving device drives the spherical crankshaft to rotate forward along the valve shaft, the valve core moves radially for a small distance under the driving of the spherical crankshaft and leaves the valve body sealing ring, a certain gap is reserved between the valve core sealing ring and the valve body sealing ring, then the valve core rotates forward along the valve shaft under the constraint of the circular arc track to open the valve, when the valve is closed, the driving device drives the spherical crankshaft to rotate reversely along the valve shaft, and before the valve core rotates reversely under the constraint of the circular arc track under the driving of the spherical crankshaft to reach the position of the valve body sealing ring, the valve core sealing ring and the valve body sealing ring can have a certain gap, and then the driving device drives the spherical crankshaft to rotate reversely for a small distance along the valve shaft, so that the sealing pair is attached.
The middle of the valve core is hinged in the middle of the spherical crankshaft, the upper part and the lower part of the outer circumference of the valve core are provided with radial short shafts, the radial short shafts are provided with rollers, and a section of circular arc-shaped track which is perpendicular to the valve shaft and matched with the rollers is arranged on the plane below the valve cover and below the valve body. When the valve is opened and closed, the abrasion of the valve body sealing ring and the valve core sealing ring is small, the valve core rotates under the constraint of the circular arc track under the drive of the spherical crankshaft, and the sealing pair can be matched even if the valve is used for a long time.
The invention will be further described with reference to the accompanying drawings.
