With the continuous expansion and development of the LED industry in the Chinese market, and the continuous improvement of the level of science and technology in the LED industry, the emergence of LED publicity vehicles has been brought about. As a new type of advertising transmission method, it has a relatively high degree of heat in recent years. So what are the characteristics of this type of LED promotional vehicle? Let's take a look at it.
First: Multifunction
The most prominent feature of LED advertising vehicles is the fast speed of transmission, which can directly receive cable television signals or wireless television signals. If you want to broadcast to the studio, it is also allowed. At the same time this video can also be uploaded directly to the Internet, want to see the playback screen, want to see the classic part can be seen again. The true meaning of LED publicity vehicle realizes the combination of dynamic and static. So, in general, LED promotional vehicles are versatile.
Second: Energy Saving
The LED publicity vehicle mainly uses the light of the outside world to change the brightness of the electronic screen. In addition, if this screen is used, the time can also be very sufficient. Generally, it can be used for more than 100,000 hours. And the entire structure of this type of car is relatively simple, so we are more convenient when dismantling, which greatly saves energy and saves manpower and material resources.
Third: Security
Although the LED publicity vehicle is relatively simple in construction, its safety factor is very high. This is because the body of this type of vehicle is equipped with two systems, a handbrake and a crash brake, which also ensures safe operation. In addition, such vehicles are also very safe in the face of natural disasters such as earthquake and rain.
Fourth: A wide range of propaganda
LED publicity vehicles are mainly aimed at the broad masses of people, so it can be based on the requirements put forward by the business, these for these groups of people, so as to achieve the maximum efficiency of propaganda.
The above is the four propagation characteristics of LED advertising vehicles that Xiaobian has summarized for everyone. I believe everyone has a more comprehensive and profound understanding of it. In general, this type of car brings a whole new experience to people, both from the visual and audiovisual perspectives. The effect of the dissemination is very significant.
A Solenoid Valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.
Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
Besides the plunger-type actuator which is used most frequently, pivoted-armature actuators and rocker actuators are also used.
Solenoid valve designs have many variations and challenges.
Common components of a solenoid valve:
-
Solenoid subassembly
- Retaining clip (a.k.a. coil clip)
-
Solenoid Valve Timer
- Solenoid Coil (with magnetic return path)
- Core tube (a.k.a. armature tube, plunger tube, solenoid valve tube, sleeve, guide assembly)
- Plugnut (a.k.a. fixed core)
- Shading coil (a.k.a. shading ring)
- Core spring (a.k.a. counter spring)
- Core (a.k.a. plunger, armature)
- Core tube–bonnet seal
- Bonnet (a.k.a. cover)
- Bonnet–diaphram–body seal
- Hanger spring
- Backup washer
-
Diaphram
- Bleed hole
- Disk
-
Valve body
- Seat
- air valve
- water inlet valve
-
control valve
The core or plunger is the magnetic component that moves when the solenoid is energized. The core is coaxial with the solenoid. The core's movement will make or break the seals that control the movement of the fluid. When the coil is not energized, springs will hold the core in its normal position.
The plugnut is also coaxial.
The core tube contains and guides the core. It also retains the plugnut and may seal the fluid. To optimize the movement of the core, the core tube needs to be nonmagnetic. If the core tube were magnetic, then it would offer a shunt path for the field lines. In some designs, the core tube is an enclosed metal shell produced by deep drawing. Such a design simplifies the sealing problems because the fluid cannot escape from the enclosure, but the design also increases the magnetic path resistance because the magnetic path must traverse the thickness of the core tube twice: once near the plugnut and once near the core. In some other designs, the core tube is not closed but rather an open tube that slips over one end of the plugnut. To retain the plugnut, the tube might be crimped to the plugnut. An O-ring seal between the tube and the plugnut will prevent the fluid from escaping.
The solenoid coil consists of many turns of copper wire that surround the core tube and induce the movement of the core. The coil is often encapsulated in epoxy. The coil also has an iron frame that provides a low magnetic path resistance.
