A wedge-shaped gate valve, comprising a valve body, a valve stem, a gate plate, and a lifting sleeve matched with the valve stem; the two gate plates are symmetrical in position, and are respectively slidingly connected with the lifting sleeve through a connecting piece; the valve stem is fixedly connected by steel bars There are sleeves.

How much do you know about the manufacturing method of wedge gate valve? Follow the editor of rubber wedge gate valve For sale to have a simple understanding!
A wedge-shaped gate valve, comprising a valve body, a valve stem, a gate plate, and a lifting sleeve matched with the valve stem; the two gate plates are symmetrical in position, and are respectively slidingly connected with the lifting sleeve through a connecting piece; the valve stem is fixedly connected by steel bars There is a sleeve; the outer surface of the sleeve has an external thread whose pitch is greater than the thread pitch on the valve stem; the sleeve is provided with a compression sleeve matching the sleeve; the lower end of the compression sleeve is connected with a compression sleeve plate. When the handwheel is rotated, the valve stem and the sleeve rotate coaxially, and the pitch of the sleeve is large, so the pressure plate descends faster than the gate plate; when the gate plate falls into the closed position, the pressure plate just presses the gate plate against the valve. On the valve seat of the body; previously the compression plate is in a position with a large gap above the gate, and does not compress the gate, thus reducing the wear of the seal. The principle of the gate opening process is the same as the gate closing process, but the process is opposite.


Preferably, the inner diameter of the sleeve is larger than the outer diameter of the lifting sleeve. When the gate valve is opened, the lifting sleeve can be raised into the sleeve, saving space.
Preferably, the compression sleeve and the compression plate are detachably connected. When the wedge gate valve is used for a long time and the accuracy of the pressing plate is reduced, the pressing plate can be removed, and the screwing length between the sleeve and the pressing sleeve can be adjusted to adjust the pressing accuracy of the pressing plate.
Preferably, the connecting member includes a connecting rod that is vertically fixed on the gate and a sleeve that is vertically fixed on the lifting sleeve; the outer diameter of the connecting rod corresponds to the inner diameter of the sleeve, the The connecting rod can slide in the sleeve.
Preferably, the surface of the connecting rod is provided with an axially long groove, and the top end of the corresponding position of the sleeve is provided with a protrusion. This structure can not only ensure the sliding stability, but also ensure that the gate and the lifting sleeve will not be separated.
The above is the introduction of rubber wedge gate valve For sale editor: about the production method of wedge gate valve.
