Instrument valve is the use of analog signal regulator, also known as analog meter valve. It determines the controlled object parameters of the analog form of the measured value and the deviation of the given value, and according to a certain regulation law to produce analog output signal to promote the actuator to eliminate bias, the controlled parameters remain in the vicinity of a given value or change in accordance with a predetermined law. In automation instrumentation, instrumentation valves are often used to integrate instrumentation output signals in order to control the manufacturing process. The adjusted parameters include temperature, pressure, flow, level, composition and so on. Meter Valve Category: Meter valve according to the energy used is divided into pneumatic instrument valve, hydraulic instrument valve and electric instrument valve three categories; According to the principle and structure can be divided into self-meter valve, base regulator instrument valve, easy to adjust the instrument valve , Unit combination meter valve and assembly type integrated control device and so on. Meter valve by adjusting the role of the instrument is divided into two, proportional instrumentation valve, PI instrument valve (proportional integral instrument valve), PID instrument valve (proportional integral differential regulator), feed-forward instrument valve. A self-acting instrument valve to be adjusted medium itself energy or after a simple conversion control valve driven to achieve automatic adjustment. Float level regulator (such as the bathroom) is the use of float on the surface of the buoyancy control valve. This regulator does not require external energy, is an on-site adjustment of the device. It is simple in structure, easy to maintain and suitable for single parameter control system with low control precision. It is very similar in principle and structure to a pneumatic actuator and is often classified as an actuator. 2 Base Instrumentation Valve An indicating recorder with an additional adjustment mechanism. It receives the signal sent by the detection element, by indicating the action of the recording mechanism drives the adjusting mechanism to send the control signal to the actuator for automatic adjustment. Dynamic indicator instruments, electric and pneumatic recorders with electric or pneumatic regulators fall into this category and are used extensively to control individual production equipment. Simple instrument valve, a signal that can directly accept the detection components, without instructions agencies, and strong specificity of the simple structure of the instrument. It also accepts the transmitter's signal. No indicator regulator and temperature alarm are easy to adjust the instrument, widely used in small and medium enterprises. 3 Unit The instrument consists of a set of regulating instruments consisting of several standard cells with independent functions. It is fully adapted to the requirements of large units and process control, enabling complex control of multiple circuits (see electric unit instrument cluster, pneumatic unit instrument cluster). 4 assembly type integrated control device referred to as the assembly type instrument, is in accordance with the requirements of a large unit or process control, use a variety of independent functional components into a combination of dedicated control device. It can be assembled according to the needs of the user, and therefore has great flexibility.
Grow Light Folding 8 Strips
Floding grow light has premium aluminum as body and heat sink,the heat dissipation is fast, but slight.
The light souce has Red, Blue, UV and IR. Blue wavelength promote the boots grow, leafy fast, Red promote blooming, flowering and fruiting.UV can kill harmful virus, IR can increase the red wavelength,make plants grow faster. Our led plant grow light is full spectrum light,can meet all the light and wavelength all the plants needs at any phases.
