Z23X-350Drilling high-pressure mud gate valveproduct overview:

High pressure mud gate valve is used in oil and mineral drilling mud circulation system equipment to control mud flow and closure,The connection form is trapezoidal thread or flange type, which is fast and convenient to install, strong in rigidity, safe and reliable, with good sealing effect between the valve seat and the gate plate, and easy to open. Both ends of the valve are connected to the pipeline for sealing, using spherical movable contact and0The movable joint combined with rubber sealing rings has reliable structural performance and is particularly suitable for situations where the center requirements at both ends of the pipeline are not high.

Working principle and purpose:

High pressure mud gate valves come in two types: non-metallic seals and metal seals. They are mainly used in oil and mineral drilling mud circulation system equipment to control mud flow and closure,The connection form is trapezoidal thread or flange type, which is fast and convenient to install, strong in rigidity, safe and reliable, with good sealing effect between the valve seat and the gate plate, and easy to open. Both ends of the valve are connected to the pipeline for sealing, using spherical movable contact and0The movable joint combined with rubber sealing rings has reliable structural performance and is particularly suitable for situations where the center requirements at both ends of the pipeline are not high.
Valve suitable for controlling mud mixture during drilling process——Abbreviated as mud valve, it belongs to the field of high-pressure valve technology. The valve comprises a valve body with inlet and outlet ends, and a flat plate gate is installed in the valve seat between the inlet and outlet ends of the valve body. The upper end of the flat plate gate is connected to the valve stem, and the valve stem is connected to the handwheel through a threaded pair. The improvement lies in that the valve seat is composed of two circular ring inner skeletons covered with rubber and a support ring to form a channel, and its horizontal cross-section is an elliptical shape with the long axis consistent with the direction of liquid flow. It is embedded in the blind hole between the inlet and outlet ends of the valve body. There is a circular arc groove with a width smaller than the thickness of the flat plate gate between the two circular ring inner skeletons covered with rubber. Due to the interference fit between the elliptical cross-section valve seat and the blind hole on the valve body, it reduces the large area of interference with the valve body, thus producing an ideal sealing effect. The circular inner skeleton in the valve seat maintains the basic shape of the valve seat for a long time, giving it sufficient service life.
