Two-way hydraulic lock is two hydraulically controlled one-way valves used together. It is usually used in load-bearing hydraulic cylinders or motor oil circuits to prevent the hydraulic cylinder or motor from sliding down by itself under the action of heavy objects. When action is required, it must be The other channel supplies oil, and the one-way valve is opened through the internal control oil circuit to connect the oil circuit, so that the hydraulic cylinder or motor can operate. Due to the structure of the product itself, during the movement of the hydraulic cylinder, due to the dead weight of the load, an instantaneous pressure loss is often caused in the main working chamber, resulting in a vacuum, which closes the one-way valve and then continues to supply oil, causing the pressure in the working chamber to rise again. Open the one-way valve. Due to the frequent opening and closing actions, the load will produce large impact and vibration during the falling process. Therefore, the two-way hydraulic lock is usually not recommended for high-speed and heavy-load conditions, but is often used for long support times and movements. Latching circuit with low speed. What is the principle of a two-way hydraulic lock? Is there a schematic diagram? Two night sky one-way valves form a two-way hydraulic lock. The principle is that the two hydraulically controlled one-way valves take the pressure of the other's oil line as the pilot oil. When there is no pressure in one line , the other side is closed at the same time.
The hydraulic lock can be regarded as a stop valve. When it is opened, the oil path is open. When it is closed, the oil path is cut off and oil cannot pass. It is used to close the oil cylinder so that the oil in the oil cylinder cannot come out. Therefore, the oil cylinder cannot move and is locked, so it is called hydraulic lock. The principle is similar to the working situation of shuttle valve. If the pressure in the working chamber is increased and then the one-way valve is opened, the load will produce greater impact and vibration during the falling process. The two-way hydraulic lock is usually not recommended for high-speed and heavy-load conditions and locking circuits with low movement speed. It is usually used in the load-bearing hydraulic cylinder or motor oil circuit and must supply oil to another circuit. Due to the structure of the product itself, it often causes instantaneous pressure loss in the main working chamber. Therefore, it is often used for long support times. Due to the frequent opening and closing actions, the hydraulic cylinder continues to supply oil during movement. The one-way valve is opened through the internal control oil circuit to connect the oil circuit. The two-way hydraulic lock is two hydraulic control one-way valves used together. A vacuum is generated to close the one-way valve so that the hydraulic cylinder or motor can operate. When action is required, it is used to prevent the hydraulic cylinder or motor from sliding down under the action of heavy objects due to the dead weight of the load. Hydraulic lock is also called compression locking valve. It is used in hydraulic systems such as cranes, tunnel boring machines, loaders and other load-bearing cylinders in mining, engineering, hoisting, ports and other machinery. In these hydraulic systems, when the oil pump stops supplying oil, or when the reversing valve is in the neutral position, the load-bearing cylinder bears unfixed forces in two directions. The pressure oil in the cylinder easily leaks from the reversing valve gap, so when A hydraulic lock is placed between the reversing valve and the cylinder to maintain pressure, prevent leakage, ensure the stability of the load-bearing cylinder piston, and ensure the normal operation of the machinery. Hydraulic control check valve. Please enumerate the principle of two-way hydraulic lock. The scientific name should be called superimposed hydraulic control check valve. Its principle is that when oil is supplied to chamber A, there is a control oil in chamber A that will force open the check valve of chamber B. On the contrary, when chamber B supplies oil There will be a check valve that controls the oil to force open the A chamber. If neither chamber is supplied with oil, both chambers AB will be closed into a one-way valve state. If both chambers AB are supplied with pressure oil, both chambers AB will will be opened simultaneously and will no longer have a one-way effect.
