DZF.OO three-purpose valve is a main component on DZ mining single hydraulic prop, it is the heart part of the prop, it can complete the working degree of the prop up column, initial support and down column, and can make the post stable It is highly known that maintaining the rated working resistance makes it a constant resistance pillar, which can ensure a safer working environment on the coal mining face.
Three-Purpose Valve Of External Injection Type Single Hydraulic Prop For Mine
There are many specifications of three-way valve. Below we will explain the parameters with common anti-flying three-way valve.
1. Rated working pressure: 30 ～ 50MPa
2. Safety valve allows Z large overflow flow: 3L / min
3. Working liquid: emulsified liquid containing 1-2% M10 or MDT emulsifier
Unloading torque: <100N. m
4. Failure analysis and elimination
5. Storage
① When the safety valve is stored, the liquid in the clean cavity should be drained, cleaned, and coated with No. 5 anti-rust hydraulic oil
② Put the plastic plug in the inlet and return port at the same time, and put it in a clean and dry place
