The usage method of superimposed relief valve mainly involves installation, pressure adjustment and daily maintenance. The following is a detailed introduction: Installing superimposed relief valves is usually installed between the reversing valve and the bottom plate. Superimposed valves of the same diameter are superimposed in a certain order and connected in series with bolts. When installing, you need to pay attention to the damping holes on the oil circuit or main valve core. The pressure valve unit with the damping hole is the pressure valve unit, and the direction valve unit without the damping hole is the direction valve unit. Ensure the connection is correct. For example, during the installation process, it is necessary to ensure that the connection between the main oil circuit of the cone valve and the pilot valve and the control oil circuit is accurate to avoid the system from operating normally due to connection errors. Pressure adjustment and adjustment steps: When performing pressure adjustment, first loosen the lock nut and rotate the pressure adjustment screw clockwise, and the pressure will rise. After adjustment is completed, the lock nut must be tightened to prevent the pressure adjustment screw from loosening, resulting in unstable pressure. Note: The minimum adjustment pressure is equal to the characteristics of the minimum adjustment pressure

The use of solenoid reversing valve mainly includes the following aspects: Power connection: Before use, confirm the power type and rated voltage used by the solenoid valve, and connect the power supply as required. The solenoid is divided into DC or AC, so the control power supply parameters must be consistent with the solenoid valve, otherwise the reversing valve may not work properly or the solenoid is burned. Slide valve function inspection: Solenoid valves have multiple slide valve functions, and there are differences between formal and reverse installation when leaving the factory. When using it, check whether the slide valve function meets the requirements to avoid affecting the normal operation of the system. Oil cleanliness: Ensure that the cleanliness of the oil meets the requirements. Since the fitting gap between the valve core of the solenoid valve and the valve body hole is small, impurities may cause the valve core to be stuck, so the filtration accuracy of the oil must be strictly controlled. Oil return port pressure: Note that the pressure of the solenoid valve oil return port T should not exceed the allowable oil return back pressure. For example, an electromagnetic reversing valve with a rated pressure of 21MPa and 31.5MPa has an oil return port.

The advantages of superimposed hydraulically controlled check valves are mainly reflected in the following aspects: compact structure and space saving: superimposed hydraulically controlled check valves adopt superimposed structure, and multiple valve spools can be stacked together to form a whole without the need for pipe connections, thereby reducing the space required by the system. This compact design makes the hydraulic system smaller and lighter, making it easier to install and layout. Easy to install and easy to maintain: The installation process of the superimposed hydraulically controlled check valve is relatively simple and the assembly cycle is short. Since the pipeless connection between the components is achieved, leakage, vibration and noise caused by oil pipes, pipe fittings, etc. is eliminated, making the system maintenance and maintenance easier. Stable performance and high reliability: the superimposed hydraulic control check valve has the characteristics of small leakage, low vibration and low noise, which can ensure the stable operation of the hydraulic system. At the same time, its high-precision grinding technology and high-quality sealing materials also improve the sealing and accuracy of the valve, further enhancing the reliability of the system

The choice of single-head solenoid reversing valve and double-head solenoid reversing valve must be determined based on the specific application scenario. Both have their own advantages and disadvantages, and it is impossible to generalize which one is better. 1. Characteristics and applicable scenario structure and function of single-head solenoid reversing valve. Single outlet design: There is only one fluid outlet, suitable for one-way flow control. Single function: Only the fluid can enter or discharge from one direction, and cannot be switched in two directions. Advantages and simple structure: small size, low cost, convenient installation and maintenance. Fast response speed: The solenoid force directly drives the valve core and moves quickly. Applicable scenarios for one-way flow control: such as one-way oil circuit switching in hydraulic systems and one-way air flow control in pneumatic systems. Cost-sensitive projects: scenarios where equipment costs are strictly limited. 2. Characteristics and applicable scenario structure and function of double-head solenoid reversing valve. Double outlet design: It has two fluid outlets, which can realize bidirectional flow control. Diverse functions: It can control the forward flow of fluid and reverse flow, flexible

The use of single-head solenoid reversing valve mainly includes steps such as installation, power connection, function inspection and manual operation. The details are as follows: Installation: The axis of the solenoid reversing valve must be installed in the horizontal direction, and installation in the vertical direction may lead to abnormal reversal or reset. The surface of the installation base plate should be ground to ensure that the flatness meets the requirements and avoids protrusions. The mounting screws should not be too loose, otherwise oil leakage may occur at the junction between the plate-type connection solenoid reversing valve and the bottom plate. Check whether the oil chamber pressure at both ends of the solenoid valve is too high. If the oil drain or oil return pipes of multiple solenoid valves are connected together, the back pressure should be too high, they should be connected to the oil tank separately. Power connection: Before use, confirm the power type and rated voltage of the solenoid on the solenoid valve, and connect the power supply as required. The solenoid should be consistent with the control power supply parameters, otherwise it may cause the reversing valve to fail to work properly or burn the solenoid. Functional inspection: Check whether the slide valve function of the solenoid valve meets the requirements, the solenoid valve is shipped from the factory

Single-head electromagnetic reversing valve is a valve that controls the flow direction of fluid through electromagnetic force, and is widely used in industrial automation, mechanical manufacturing, energy, environmental protection and other fields. Its core function is to use the on-off power of the solenoid to switch the valve core position, thereby controlling the direction of fluid in the hydraulic or pneumatic system. The following are its main application scope: 1. Hydraulic and pneumatic system control application scenarios for industrial automation and mechanical manufacturing: hydraulic systems of machine tools, injection molding machines, die casting machines, stamping machines and other equipment, and control the movement direction of actuators (such as hydraulic cylinders and cylinders). Advantages: Fast response speed (millisecond level), high control accuracy, and adapt to high frequency action needs. Application scenarios of automated production lines: material conveying, assembly lines, robots, etc., to realize clamping, positioning, and moving workpieces. Advantages: Compact structure and easy to integrate into automated control systems. 2.
