Hydraulic multi-way directional pneumatic valve of the self

pneumatic valve or multi-channel pneumatic hydraulic multi-way directional valve, is a kind of hydraulic actuators can control multiple directional control pneumatic valve combination, it is more than two reversing pneumatic valve as the main body, set the reversing pneumatic valve, one-way pneumatic valve, relief valve, pneumatic valve and brake valve of oil and gas is equal to the integration of multi-function integrated pneumatic valve. With the arrival of it, the walk, including engineering machinery, mechanical hydraulic system becomes compact structure, simple line, small pressure loss. Below is the detail all kinds of hydraulic multi-way directional pneumatic valve:
( ） According to the structure of pneumatic valve is mainly divided into integral type and divided. Integral multi-channel pneumatic valve will each directional control of pneumatic valve and various functions of the pneumatic valve integrated in a pneumatic valve body. It has compact structure, light weight, and the advantages of small pressure loss, but also has the generality is not strong, the pneumatic valve casting requirements higher shortcomings. Shard type multi-channel pneumatic valve, pneumatic valve is also called modular multiplexed by a certain number of reversing pneumatic valve unit, its replacement is simple, easy maintenance, use range wide, but the volume and weight of the pneumatic valve is larger, and are more likely to leak.
（ ） According to the form of oil can be divided into parallel, serial, parallel and composite oil, etc. Oil multichannel parallel pneumatic valve of each part of the reversing pneumatic valve inlet pressure are equal, oil return directly with total oil mouth is same. In multigang reversing pneumatic valve moves at the same time, the pressure oil will enter first load of smaller actuators. Series oil multi-channel pneumatic valve in addition to the first, the rest of the league of the oil inlet is connected with a united oil mouth, use this form of multi-channel pneumatic valve, hydraulic pump to provide must be able to overcome the pressure of the sum of all the working load of the actuator pressure, therefore the operation when the resistance is bigger. Series-parallel oil multi-channel pneumatic valve refers to the union the reversing of the pneumatic valve inlet used in tandem, oil return mouth with connected in parallel with the total oil mouth. Compound oil is to point to by two or more of the above oil combination form of oil.
