What Are the Working Principles and Characteristics of the High Pressure Mud Gate Valve?

Ⅰ. Product essentials of high-pressure mud gate valve

High-pressure mud gate valves have two kinds: non-metallic seal and metallic seal, mainly used in slurry circulating system device of oilfield drilling, to control distribution and closure of serum gas.

Connecting format is trapezoidal thread or flange type, easy to install, with strong rigidity and stability. The high-pressure mud gate valve's seat and wedge are sealed well, easy to open up.

Connect and seal both ends of the valve and air tube, and adopt movable joint combined sphere's movable contact with 0-type rubber seal. The product has reliable structural performance and is especially suitable for undemanding ends and the center of the air tube.

Ⅱ. Working principles of the high-pressure mud gate valve

The valve suitable for drilling fluid mixture is called mud pump valve for short, belonging to high-pressure valve technical field. This valve has a valve body with access fluid ends, the flat gate valve is installed on the valve seat between access fluid ends, and the top flat gate is connected to the valve rod.

The valve rod and handwheel are connected by a screw. The improvement point is that the valve seat's passage is made up of hoops' inner frame and supporting ring.

The horizontal section of the high-pressure mud gate valve shows a long axis and oval flow direction. The blind hole between in-and-out fluid ends has the gap between the skeleton within two rings surrounding rubber. Valve seat in oval section reduces large-area excess with valve body in a blind hole, which can reach an ideal sealing effect.

However, the skeleton within rings keeps the basic shape of the valve seat, so it has enough lifetime. It is suitable for drilling and oilfields. Relevant products include parallel gate valve of clamped-in style, parallel gate valve of sulfur resistant welding type, parallel gate valve of flange type, and flat gate valve.

Ⅲ. Features of the high-pressure mud gate valve

1. Shutter's bottom opens a pilot hole.

2. Valve body has high loading capacity.

3. Channel is linear with small flow resistance.

4. High-pressure mud gate valve has reliable sealing and small friction.

5. Double seal.

6. Realize adjustable flow.

7. Adopt a floating valve seat, two-way switch, reliable sealing, and flexible switch.
