Speaking of hydraulic synchronous valves, you may not have heard of them very much. In fact, they are widely used in many industrial fields. So, is it good? Today, let's take a look at the relevant introduction of hydraulic synchronous valves through the following content. What is a hydraulic synchronous valveHydraulic synchronous valve, also known as speed synchronous valve, is a general term for diversion valve, collection valve, one-way diversion valve, one-way collection valve and proportional diversion valve in hydraulic valves. Synchronous valve is mainly used in dual cylinder and multi cylinder synchronous control hydraulic systems. There are many methods to achieve synchronous motion, but among them, the synchronous control hydraulic system using a diversion valve synchronous valve has many advantages such as simple structure, low cost, easy manufacturing, and strong reliability. Therefore, synchronous valves have been widely used in hydraulic systems. The synchronization of the diversion and collection valve is speed synchronization. When two or more cylinders are subjected to different loads, the diversion and collection valve can still ensure their synchronous movement.Types of hydraulic synchronous valvesAccording to the adjustment method, it can be divided into fixed diversion and collection valves, self-adjusting diversion and collection valves, adjustable diversion and collection valves, as well as combination adjustable diversion and collection valves with self-adjusting and adjustable combinations. The above series of hydraulic valves can be designed as small flow diversion and collection valves, among which fixed structure synchronous valves can be divided into two structures: directional piston type and hook type.This series of hydraulic valves can also be divided into equal flow diversion valves and proportional flow diversion valves according to the flow distribution method, and the commonly used ratio is 2:1. It can also be designed as a small flow synchronous valve according to the required ratio.Working principle of hydraulic synchronous valveThe hydraulic synchronous valve is a special and comprehensive hydraulic bridge consisting of two A-type hydraulic half bridges composed of a valve core d and a valve body c, as well as two variable throttling hydraulic resistance control bridges. It can be represented as a hydraulic bridge form.The lower chambers of the two hydraulic cylinders are controlled by two A-type hydraulic half bridges, and the upper chambers of the two hydraulic cylinders are controlled by two variable throttling fluid resistances. The A-type hydraulic half bridge is composed of two variable throttling dampers; The B-type hydraulic half bridge consists of a fixed throttling damping and a variable throttling damping; The C-type hydraulic bridge consists of a variable throttling damping and a fixed throttling damping, with their pressure and flow gain characteristics. As can be seen, the pressure and flow gain of A-type hydraulic half bridge are the highest, twice that of B-type and C-type half bridges, which means that the control accuracy of A-type hydraulic half bridge is the highest.
