Various types of hydraulic control valve specifications, the system can be the highest pressure and the actual flow through the valve (from the condition map and system diagram) as the basis and consider the valve control characteristics, stability and port size, dimensions, Installation and connection methods, methods of operation, etc., from product samples or catalog selection. Jin Ze hydraulic production hydraulic system supporting various types of hydraulic control valve selection precautions are as follows: 1, the actual flow of hydraulic valve The actual flow of hydraulic valve and the oil string, parallel connection: tandem oil flow throughout the same; at the same time work The flow of the parallel oil circuit is equal to the sum of the flow of each oil circuit. In addition, for systems using a single-piston cylinder, pay attention to the difference in oil return flow when the piston is extended and retracted: the ratio of the flow rate of the rod-less oil into the rod- Two cavity area ratio equal. 2, the rated pressure of the hydraulic valve and the rated flow The hydraulic control valve rated pressure and rated flow should generally be close to its use of pressure and flow. For systems requiring high reliability, the valve should be rated at a pressure higher than its operating pressure. If the rated pressure and the rated flow is less than the use of pressure and flow, it is easy to cause hydraulic clamping and hydraulic power and the valve work quality adversely affect the sequence valves and valves in the system, the flow through the flow should not be much smaller than rated Flow, otherwise easy to produce vibration or other unstable phenomenon. For flow valves, attention should be paid to their minimum steady flow. 3, the installation and connection of the hydraulic valve As the valve installation and connection of the follow-up design of the hydraulic device structure has a decisive influence, so the choice of hydraulic valve hydraulic control device should be integrated approach to what is known. For example, the hydraulic valve plate connection, because the valve can be mounted on the circuit board or block, on the one hand to facilitate system integration and hydraulic device design rationalization, on the other hand when replacing the hydraulic valve without removing the tubing, installation and maintenance more convenient; If stacked valves are used, the series of profiles of stacked valves should be studied for pressure and flow, and so on. 4, the direction of the control valve for the simple structure of the ordinary check valve, the main should pay attention to its opening pressure reasonable choice: lower cracking pressure, can reduce the flow through the check valve resistance loss; However, for the back Check valve used in the one-way valve, the opening pressure is higher, in order to ensure adequate back pressure. For the pilot operated check valve, in addition to the relevant notes in this valve, in order to avoid abnormal vibration and noise caused by the system, it should also pay attention to the reasonable selection of its relief mode: When there is a back Pressure, should use the leak-style, other cases optional internal bleed-style. For the valve, should pay attention to meet the system requirements for automation and operation cycle starting from the manual, mechanical, electromagnetic, electro-hydraulic and other types of reasonable choice of its type. Correct selection of the valve slide valve median performance and grasp the transitional quasi-state function. For hydraulic lock (double check valve) to lock the hydraulic actuator system should be used, "H", "Y" shape of the central function of the spool valve, so that the valve when the center, The control chambers of the two pilot operated check valves are all connected with the fuel tank to ensure the reliable reset of the hydraulic check valve and the good locking status of the hydraulic actuator. The selected spool valve reversing valve position in the transition to the transitional position, the oil should not be completely blocked situation, otherwise it will lead to infinite pressure system instantaneous and lead to pipeline explosion and other accidents.
