Pneumatic control valve to find lanuo valve pneumatic control valve input signal


Pneumatic control valve, pneumatic plastic film valve, pneumatic fluorine lining valve, pneumatic continuous high temperature control valve to accept industrial automation automatic control system to adjust the data signal to adjust the pipeline medium total flow, working pressure, temperature and other main processing parameters. Pneumatic plastic film regulating valve is characterized by simple operation, rapid response, and safety system, without the use of explosion-proof countermeasures.
N can be integrated directly acting valve such as: Angle seat valve, cut-off valve, pulse damper valve, etc., the selection of external line phase sensor constituted valve automatic control system; And can be integrated Angle stroke arrangement pneumatic actuator valves such as: valve, disc valve, and diaphragm pneumatic control valve, selection of embedded Angle stroke arrangement sensors constitute the valve automatic control system

Pneumatic control valve is an automatic adjustment of medium working pressure, total flow, temperature of the valve, the structure of pneumatic plastic film electric actuator, regulating valve, and other accessories. Pneumatic control valve work to compressed gas as the driving force, pneumatic actuator as the driving method, control valve as throttle valve medium overcurrent total area size, cooperate with each other to accept digital signal quantity 4-20mah, complete the pipeline medium total flow, working pressure and other technical parameters of fine manipulation. Pneumatic control valve structure basic principle:
Under the rapid development of industrial control automation level, pneumatic control valve as an excellent actuator has also been applied, this control valve has the characteristics of reliable posture, simple structure, in order to ensure the optimal operation of the system has a very key practical significance, The following is a further analysis of the selection and use of pneumatic control valve in the whole process of chemical plant automatic control system.
For the valve that the working pressure is too greater than and has the disconnection effect on the main stem pipe, the compressive strength and air tightness test experiment should be carried out, and the application is allowed after reaching the standard. Pneumatic control valve is powered by compressed air device, cylinder, for electric actuators, and valves, converter, vacuum electromagnetic valve, a valve, air cylinder, gas filters, such as accessories to push valve, complete the switch quantity or proportion adjustment, accept the regulation of automatic control in the automatic control system data signals to adjust line medium: Total flow, working pressure, temperature, liquid level meter and other main parameters of the whole process of processing. Pneumatic control valve is characterized by simple operation, quick response, and safety system, without the use of explosion-proof countermeasures.
In the whole process of the use of pneumatic control valve, cavitation and flash are two common conditions, especially in the case of large pressure difference. Cavitation and flash will obviously harm the surface of the regulating valve, resulting in the leakage of the regulating valve surface, and even the loss of the ability to adjust the work. Therefore, pneumatic control valve in the design of the need to be based on the technical standards on the spot, scientific and reasonable design scheme. So, what is the way to prevent cavitation and flash pneumatic control valve
Assembly production equipment for every industry is relatively serious, how much more the principle of pneumatic control valve of sensitivity is high then the complete assembly process, to ensure that the appropriate assembly? We tend to focus on the principle of pneumatic control valve assembly method, anxiety is due to no accurate assembly, it will be difficult to ensure that applications can smoothly in the future, Then there will be many common failures, which directly affect the service life of the pneumatic control valve.
Leke valve to strengthen the concept of market competition, to build a sense of team. Adopted the operation mode of the traded won impressive score on the test in the field of the valve, make the competition in the business services, it may come from companies to adhere to the relentless pursuit of perfection, the quality of the products to adjust quality and have the mechanical equipment machinery and equipment mainly USES pneumatic – valve to the masses, the masses.
The difference between electric control valve and pneumatic control valve depends on the application of different driving equipment, that is, the executive body, and the valve itself is no difference. The difference between the implementation of the main working conditions, such as chemical plants and other provisions of explosion-proof type of place, the most common application is pneumatic valve, due to high safety factor demand, and the price is low, with intelligent locator can be on the system bus, the control method is also simple.
Company has established a sound quality management and service security system, pneumatic control valve enterprises have passed and many national invention patents, lasting three years to get excellent jiading company, with the help of a group of new material product research and development and quality control, ensure technical goods, promote enterprise technology innovation, build * * company competition ability. The products are used in food, biological medicine, steel and metallurgical industry, textile industry, petrochemical industry and many other well-known enterprises and major engineering projects, and create a good cooperative relationship with customers.
Valve locator: By different period, the development trend of the pedal, there are all intelligent, also have other types, the early valve locator is the key to the control valve accessories, pneumatic – valve facilities often and application, it accepts the input and output data of automatic control system of signal, and then to its input and output data signal to control pneumatic control valve, when the valve position, Seat offset is fed back to the valve locator according to the mechanical equipment. Valve position can be based on electronic signals, or in addition to the valve position power switch to send data data signals to the power monitoring system
