Design Features:
1.Body structure
The valve body of our DBB Plug Valve includes valve body, valve core, valve disc (embedded in main sealing ring), end cover, chassis, packing and other main components. The valve core and disc are the core of the valve body part. The valve core is fixed in the valve body with the upper and lower trunnions, the flow channel opening is in the middle, and the two sides are wedge-shaped surfaces. The wedge face mill has dovetail guide rails that are attached to two discs on both sides. The disc is the main sealing element and has a cylindrical surface. Accuracy of Class B hard seal can be achieved. The cylindrical surface is milled with a groove circle, and the main sealing ring is permanently embedded with fluorine rubber or nitrile rubber, etc. by molding and vulcanization, which plays the role of hard sealing and soft sealing when the valve is closed.
2.Manipulator structure
The manipulator is mainly composed of signs, hand wheel, spindle bushings, ball pins, brackets and other components, which are fixed on the end cover and connected with the spool rod by connecting pins. The manipulator part is the actuator of the action. Close the valve from the open position, turn the hand wheel clockwise, the valve core rotates 90° first, and drives the valve disc to rotate to the valve body flow channel position. Then the valve core moves down in a straight line, driving the valve disc to expand radially and approach the inner wall of the valve until the soft seal is pressed into the groove, so that the surface of the valve disc is in contact with the inner wall of the valve.
3. Close the process.
Open the valve from the closed position, turn the handwheel counterclockwise, the valve core first moves straight up, and then rotates 90° after reaching a certain position, so that the valve is in a conducting state.
4. DBB or DIB Function
The DBB Plug Valve (double block and bleed plug valve) also named GENERAL VALVE, Twin Seal plug valve. this constant wear by using two seating slips mounted independently on a tapered plug by dovetails, which mechanically retract from the seating surface prior to rotating. This provides a bubble-tight verifiable dual seal without seal abrasion.
