Description
The three-way valve is the core component of the single hydraulic prop, which directly affects the life and use of the single hydraulic prop. The three-way valve is a key part of the single hydraulic prop. It acts as a liquid injection column, overload overflow, and a load drop column.
The three-way valve is the core component of the single hydraulic prop, which directly affects the life and use of the single hydraulic prop. The three-way valve is a key part of the single hydraulic prop. It acts as a liquid injection column, overload overflow, and a load drop column.
The three-purpose valve is composed of a one-way valve, an unloading valve and a safety valve, and is the heart of the externally-injected single hydraulic prop. The pillar is opened and supported by its one-way valve; the recovery of the pillar is completed by its unloading valve; The safety valve is used to slowly lower the struts when the struts are overloaded, and the protection struts are not damaged.
The three-purpose valve of the externally-injected single-unit hydraulic prop is a valve group that controls three steps of lifting, carrying and lowering the external hydraulic unit of the external injection type, and is composed of a one-way valve, a safety valve and an unloading valve member. The valve is the heart of the hydraulic strut. It is threaded on the post of the column with the threads of all the cylinders and sealed with the stud by an O-ring on the valve barrel.
If there is no single-valve hydraulic prop, it can’t be used. If the single hydraulic prop can’t be used, it can’t be used. If it can’t be constructed, it will affect the overall progress. You said that it is important! How much money was lost in the day of the delay? The white flowers were ran like this, and the tables were light.
The three-purpose valve is composed of a one-way valve, an unloading valve and a safety valve. During operation, the high-pressure liquid opens the one-way valve of the injection valve body through the liquid injection gun, and the high-pressure liquid enters the lower cavity of the pillar, and the living column rises.
After the injection is stopped, the check valve is automatically closed and the post is fixed at a certain position. When the pressure of the top plate increases and the pressure in the inner cavity of the pillar exceeds the set pressure of the safety valve, the safety valve opens the liquid overflow, and the pressure in the inner cavity of the pillar decreases. When the pressure in the inner cavity of the pillar is lower than the pressure of the safety valve closing valve, the safety valve is closed. When the column is lowered, the unloading handle is turned, the valve sleeve is moved axially, the unloading valve is opened, the emulsion in the column overflows, and the living column is retracted under the action of the self-weight and the return spring.
