Sany Zoomlion Logic Valve Customizable For Concrete Pump Truck Hydraulic Spare

Product Specification

Sany Zoomlion Logic valve can be customizable for Concrete Pump Truck hydraulic spare parts

Product Description/Features:
  

The logic valve, also known as the taper valve, has two pipe connection ports A, B and a control port C. The upper chamber of the taper valve is connected with the pilot control valve, which is communicated with the control oil circuit.

From the working principle, it is equivalent to A hydraulic control check valve, when the control oil port C is connected to the fuel tank, the taper valve is opened, and the two oil ports A and B are connected, so the pilot control valve is used to relieve or pressurize the C port, and the opening and closing of the taper valve can be realized. The control mode can be divided into single guide, multiple guide, flow control, electromagnetic control and so on.

The combination of taper valve and small flow solenoid valve can form a direction valve. The combination of taper valve and various pilot pressure valves can form a variety of pressure control valves. If the B chamber is the oil return chamber, the valve acts as an relief valve. If chamber B is a branch of the connected system, the valve acts as a sequence valve.

The valve body is placed in the oil circuit plate, the noise is small, the vibration is small, the mechanical operation is stable, the multi-functional characteristics simplify the needs of other valves, and avoid the oil leakage caused by pipeline installation, easy installation and reduce costs.
It can be seen that a cone valve is correspondingly equipped with a solenoid valve and pilot pressure valve and take speed regulation measures, you can play the role of reversing valve, pressure valve and throttle valve in the system, at present, this valve is used for high pressure, large flow or large flow hydraulic system. Applicable machinery range: large machine tool, folding machine, die casting machine, plastic injection molding machine, copper rolling machine and all kinds of heavy industrial machinery and vehicles and ships.

The working principle of the logic valve  is mainly based on control signals and logical operations.
The logic valve is composed of a working element, a control element and a spring, through which the control signal is received and input into the working element, thereby changing the working state of the working element. These control signals can be digital signals or analog signals, digital signals are discrete, only two states, namely 0 or 1; Analog signals, on the other hand, are continuous and can take any value within a certain range. Inside the logic valve, the input signal is converted to a digital signal for calculation, and the output signal is converted to an analog signal output.

In addition, the working principle of the logic valve is also similar to the logic gate circuit, through the input signal and its own internal logic operation, an output signal is obtained to control the system. The logic valve contains a plurality of input terminals and an output terminal, each input terminal receives a signal, and an output signal is obtained according to the logic operation. For example, the logical operation rule of an and gate is: if and only if all input signals are 1, the output signal is 1, otherwise the output signal is 0.
