The drilling mud tank bottom valve, also known as the mud tank bottom flow valve or seabed valve, is an important part of the drilling mud tank. This valve is mainly used to control the suction and discharge of mud in the mud tank, and as a switch for inter-chamber balance control.
In terms of structure, the drilling mud tank bottom valve usually adopts an end-face sealing valve plate and a rotary lifting mechanism to achieve the connection and isolation of the tank bottom pipeline. It is mainly composed of valve body, valve stem, hand wheel, lifting rod, valve plate, bearing and other components. The opening and closing of the valve is driven by the rotating hand wheel to drive the lead screw, so that the valve stem moves up and down, and then drives the valve plate to produce a lifting effect, so as to achieve the clutch of the valve plate and the sealing seat.
In drilling operations, the role of the mud tank bottom valve is crucial. It not only needs to withstand harsh conditions such as high pressure, high temperature and corrosion, but also needs to ensure the smooth suction and discharge of mud to maintain the normal progress of drilling operations. Therefore, the performance and service life of the mud tank bottom valve directly affect the efficiency and cost of drilling operations.
In general, the drilling mud tank bottom valve is a key control device. Its compact structure, stable performance and reliable sealing performance make it widely used in drilling operations. At the same time, with the continuous development of drilling technology, the mud tank bottom valve is also constantly improved and optimized to adapt to more complex and harsh drilling environments.
