Multi directional valves play an important role in hydraulic systems, as they can achieve various functions of the hydraulic system, such as controlling the forward and backward movement of hydraulic cylinders, and controlling the forward and reverse rotation of hydraulic motors.
Multi directional valve is a combination valve composed of two or more directional valves as the main body. According to the requirements of different hydraulic systems, valves such as main safety valve, one-way valve, overload valve, oil replenishment valve, diversion valve, brake valve, etc. are often combined together. Therefore, the multi way directional valve has the advantages of compact structure, simple pipeline, low pressure loss, and easy installation. Widely used in walking machinery. To prevent hydraulic pump overload, a main safety valve is installed in the oil inlet chamber of various directional valves as the overall safety valve of the entire hydraulic system. According to different valve body structures, a one-way valve is installed in the inlet chamber or slide valve of the valve body. Its function is to prevent pressure oil from flowing back to the oil tank when the slide valve changes direction, thereby overcoming the nodding phenomenon during operation. When the hydraulic cylinder of a certain mechanism is not working, the corresponding slide valve is in the neutral position, and the two working oil ports are blocked. At this time, due to the work of other mechanisms, the oil pressure of this hydraulic cylinder can be very high. To prevent overloading of the hydraulic cylinder and its oil pipes, an overload valve should be installed at this oil port. In some hydraulic machinery, when the inertia of the working mechanism is large or the load drops faster than the speed generated by the oil supply flow rate, the Dalan hydraulic system Necessary oil replenishment valves can be installed inside the multi way directional valve to avoid suction phenomenon. Sometimes two working hydraulic systems share a hydraulic pump. When one of the hydraulic systems only requires partial flow from the pump, a diversion valve can also be installed inside the multi way directional valve. Considering certain institutions that require the engine head to be turned off Do not manipulate the handle by mistake. The danger of cargo tipping over and prevention of hydraulic cylinder emptying; Or in vehicles with static fluid transmission, in order to overcome acceleration on slopes, a brake valve needs to be installed in the multi way directional valve
