Valve core adjustment and sealing effect of shallow Manifold block hydraulic valve – working principle of Manifold block valve
Manifold Block hydraulic valve manufacturer: In the process of use, the Manifold Block hydraulic valve can be adjusted by using the area of the throttle port between the regulating valve core and the valve body and the local resistance convection generated by the equipment, so that the operation speed of the actuator of the Manifold Block hydraulic valve can be controlled.

After the adjustment of the hydraulic valve orifice area, in use can be the load pressure change little and operation uniformity requirements of the actuator movement speed basically keep its stable, in the process of load pressure change, can keep the throttle valve inlet and outlet pressure difference for a fixed value.
In operation, the Manifold Block hydraulic valve is mainly used to control the pressure, direction and flow of the liquid, and the damage of the sealing element is a common phenomenon, the main factor is the impurities in the working fluid. These impurities grind between the sealing elements, causing the valve to leak, if the filter accuracy of 3 / um filter, hydraulic valve life can be compared to 10 times the use of 10um.
Manifold Block hydraulic valve manufacturers say that although the parts of the hydraulic valve are mostly bolted, the product is designed for non-disassembly. If there is no special equipment or technology, forced disassembly is likely to cause damage to the hydraulic valve. Therefore, before disassembly, we should master the structure of the hydraulic valve and the connection between the parts, and record the position relationship between the parts when disassembly.
The above is the information sharing brought by Manifold Block hydraulic valve manufacturers, to learn more about the introduction of relevant knowledge, welcome to pay attention to our official website.
The working principle of diverting and collecting valve
Diverting and collecting valve, also known as: synchronous valve, is a set of hydraulic diverting valve, collecting valve function in one of the independent hydraulic devices. Is the hydraulic valve in the diverting valve, collecting valve, one-way diverting valve, one-way collecting valve and proportional diverting valve. The synchronous valve is mainly used in the two-cylinder and multi-cylinder synchronous control hydraulic system. Usually there are many methods to realize synchronous movement, but among them, the synchronous control hydraulic system which adopts the diverting and collecting valve – synchronous valve has many advantages, such as simple structure, low cost, easy manufacture, strong reliability and so on, so the synchronous valve has been widely used in the hydraulic system. The synchronization of shunt collecting valve is speed synchronization, that is, when two cylinders or more cylinders respectively bear different loads, the shunt collecting valve automatically adjusts through the internal pressure and flow sensitive parts, so that the cylinder movement keeps synchronous.
Diverting collecting valve according to the adjustment mode is divided into: fixed diverting collecting valve, adjustable diverting collecting valve and self-regulating diverting collecting valve. The fixed structure of the synchronous valve can be divided into reversing piston and hook type two structures. Diverting and collecting valve according to the flow distribution mode can also be divided into: equal flow and proportional flow, proportional flow is often 2:1 flow distribution mode.
The diverting and collecting valve is mainly used in the hydraulic double-cylinder and multi-cylinder synchronous control system. There are many ways to realize synchronous movement, but among them, the synchronous control hydraulic system using the split collecting valve has many advantages, such as simple structure, low cost, design, complete set, easy debugging and use, strong reliability, so the split collecting valve has been widely used in the hydraulic system.
The function of the shunt valve is to make the hydraulic system by the same oil source to two or more executive components supply the same flow (equal shunt), or according to a certain proportion to the two executive components supply flow (proportional shunt), in order to achieve the speed of the two executive components to keep synchronous or fixed ratio relationship. The function of the collector valve is to collect equal flow or proportional oil return from the two actuator elements in order to achieve speed synchronization or fixed ratio relationship. Diverting collecting valve has the function of diverting valve and collecting valve.
The accuracy of the diverter valve is generally 2%, which means that when the stroke of two cylinders is 1m, when one of the cylinders reaches the stroke end, the distance between the other cylinder and the stroke end is within 20mm. In other words, when one cylinder reaches 500mm, the other cylinder is within the range of 500±10mm (as long as the requirements of the valve are met).
