ZJGH4"-5000PSI(10000PSI)Meeting of the drilling fluid By Mud valveHigh pressure from azelaicThree linksStoneElbowHigh-pressure hoseShort FestivalComposed Pressure Gauge. Valve Group used the ground goose-shaped structure of three, A compact structure, Small fluid resistance, To give full play to power characteristics. Drilling Taiwan group using different-diameter valve Stone, Single-tube can be used directly, Ease of use at the scene. Azelaic used by the high-pressure high-strength alloy steel manufacturing, And after heat treatment. Mud valve and the valve seat gate are used carbide spray, Scour with tolerance, Corrosion resistance characteristics, Life improved valve, Small and operating torque, Open Light. Meeting of the elbow, Reducer, Direct links and Stone, and other high-strength alloy steel casting, Thickening of the wall, And the heat treatment, To fully meet the requirements of strength and corrosion resistance. The high accuracy of the parts used for processing, To ensure manufacturing quality, High-pressure parts of the former have been assembling in hydrostatic strength and sealing test, Strict quality assurance factory.

Installation:
1. Installation, All should be thoroughly cleansed by the sealing surface and seals the previous trench, Smear oil, removal of offal pipeline.
2. Carefully check whether fastening linking different parts.
3. When the relocation of parts can be open, Clean pipeline,
Oil and occupies a position after bandaging Tu, So the milk and Touch
Bad Silk Deductionand enter the sealing surface.

The use of points, and maintenance:
1) regularly to add the slurry valve calcium-based grease, maintenance valve.
2) periodic inspection of the site and connect the fixed bolts loosening.
3) found leakage sealing parts, and replace seals.
4) maintain the appearance of a clean periodic anti-corrosion paint.
Note: only as a slurry pipeline gate valve closed, Opening them, Not to throttle use, The use of salt to prevent bad expenditure sealing surface.
