Product Description
Product Description
Waste air valve is also called oil and gas separator, pressure control valve. The separation between the compressor outlet and the condenser inlet improves the heat transfer in the condenser and evaporator.
Pneumatic valves are driven by compressed air. Pneumatic valve procurement only clear specifications, categories, industrial pressure to meet the procurement requirements of the practice, can be used to control air, water, steam, all kinds of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. It is not perfect in the current market economy environment. Because pneumatic valve manufacturers in order to product competition, they are in the pneumatic valve unified design concept, different innovation, the formation of their own enterprise standards and product personality. Therefore, it is very necessary to put forward detailed technical requirements in the procurement of pneumatic valves and achieve consensus in coordination with manufacturers as an attachment to the procurement contract of pneumatic valves. This type of valve should generally be installed horizontally in the pipeline.
The use of compressed air to drive the movement of multiple groups of combined pneumatic piston in the actuator, the transmission of force to the beam and the characteristics of the inner curve track, drive the hollow spindle for rotating movement, compressed air disc to each cylinder, change the inlet and outlet gas position to change the direction of spindle rotation, according to the load (valve) required rotational torque requirements, can adjust the number of cylinder combination, drive the load (valve) work.
Two five-way solenoid valve is usually used with double acting pneumatic actuator, two is two positions controllable: open - off, five is five channels of ventilation, one of which is connected with the air source, two of which are connected with the air inlet and outlet of the external air chamber of the double acting cylinder, two of which are connected with the air inlet and outlet of the internal air chamber. The specific working principle can be referred to the working principle of the double acting pneumatic actuator. Due to the increasing number of control methods and means, there are many methods used to control pneumatic actuators in actual industrial production and control, which are commonly used as follows.
Intelligent display instrument
Intelligent display instrument is used to monitor the working state of the valve, and control the valve execution period of the work of the instrument, it through two way position sensor monitoring the working state of the valve, determine whether the valve is in the open or closed state, through programming record valve switch numbers, and there are two ways and the valve opening corresponding to 4 ~ 20mA output and bipedal normally open normally closed output contact. Through these output signals, control valve switching action.
Control system
The application of PLC in the control system is more and more widely, because this program is developed on the PLC of OMRON, so the PLC of OMRON is introduced.
Hardware components: 1 computer, 1 set of PLC(including CPU, I/O module, ID212, OC224, AD003 module), 2 relays, 2 solenoid valves, 1 pneumatic valve actuator.
General requirement
Pneumatic valve
Pneumatic Valve (11 sheets)
1. Specifications and categories of pneumatic valves produced shall meet the requirements of pipeline design documents.
2, the model of the pneumatic valve should be indicated according to the national standard number requirements. If the enterprise standard, should indicate the relevant description of the model.
3, pneumatic valve working pressure, requirements ≥ pipeline working pressure, without affecting the price of the premise, the valve can withstand the working pressure should be greater than the actual pipeline pressure; Pneumatic valve closed condition of any side should be able to withstand 1.1 times the valve pressure value without leakage; Valve open condition, the valve body should be able to withstand the requirements of two times the valve pressure.
4, pneumatic valve manufacturing standards, should indicate the basis of the national standard number, if the enterprise standard, the procurement contract should be attached to the enterprise documents.
