Directional control valve pilot valve innovative design tips
First, the pilot valve Overview: Directional valve hydraulic system is the most commonly used in a valve. How its performance will be directly related to the performance of the entire hydraulic system thus affecting the quality of the system operation. The large flow valve reliability depends mainly on the reliability of its pilot valve commutation [2]. The current pilot valve pilot valve are mostly cone valve or needle valve, these valves often because of the working medium pollution caused by system failure. Among them, the inherent deficiency of the pilot valve is an important reason. Second, the structure and working principle Pilot valve is composed of a wet valve solenoid, spool, transmission plunger, valve sleeve, thimble rod, steel ball, ball seat, reset spring. Spool and valve body thread. One end of the transmission plunger is connected with the armature of the electromagnet, and the other end is pressed against the steel ball. Therefore, whether it is the upper end of the electromagnet thrust or the lower end of the spring force makes the two balls and the thimble into a relationship. Each end of the thimble rod and the spool has a ring-shaped control chamber and is respectively communicated with the radial bore on the spool. This is a two-position three-way double ball normally closed solenoid valve. When the electromagnet is powered off, the pressure oil entering from the P cavity directly acts on the ball seat of the pilot valve, and the elastic force of the reset spring also acts on the ball seat, so that the lower valve port of the pilot valve is closed and the upper valve port is opened , So that the pressure oil circuit and the control circuit A block, control circuit and the oil return circuit T open. In this case, the control circuit is under unloading condition. When the electromagnet is energized, the transmission plunger pushes the upper steel ball to move downward, the upper valve port closes and the lower valve port opens. Thus blocking the control of the oil circuit and the return of the channel, at the same time the pressure circuit and the control of the oil circuit opened. Pressure oil through the pilot valve control chamber into the body of the inclined hole to control the oil in working condition. Third, the pilot valve innovative design tips: starting from the structure of innovative design. Prominent feature is the use of a double-ball valve structure and its plug in the main valve body, which will be reversing its reliability, sensitivity, anti-pollution ability, life and other performance indicators greatly improved, the system failure rate is greatly reduced. After years of widespread use of the user to reflect well. First, the traditional pilot valve is a separate part and is usually connected to the main valve in some way. The innovation of this design is that its pilot valve is presented in the form of a spool. It is a cartridge with the main valve share a valve body. This not only eliminates the need for a valve body to simplify the overall structure and as a pilot valve can be flexibly mounted on the various types of directional valve. In particular, it is more convenient to use the solenoid valve. In this local area similar to a common part. 2, Secondly, most of the pilot valves in the current domestic and foreign directional control valves are needle valves or cone valves. Such as the United States SAUERSUNDSTRAND MC34X-type valve for the two pilot valve is normally closed two two-way valve. MC series of products with its advanced technology marketing around the world, in our country also has its vast market. However, due to its pilot valve is a needle valve, the seat hole diameter is very small, together with the main valve orifice orifice diameter is small, which only works in the case of high cleanliness of the medium to work properly. Otherwise it is easy to block. The valve with double ball valve structure, not only good sealing, less leakage, and there is no hydraulic clamping problem, even if the oil in the larger particles of pollutants, there will be no blockage, but also to ensure the normal operation of the hydraulic system. This is its salient features. 3, the development of various types of directional control valve series, due to the use of advanced proprietary pilot valve with independent intellectual property rights, so that it reverses the work of reliable, sensitive and long life. In particular, the use of ball valve structure so that they are extremely anti-pollution ability, coupled with simple structure, easy to use and maintain, but also the price of natural advantages, which is the hydraulic system to control the direction of the valve to replace imported products, the ideal hydraulic parts
