Piston flow control valve works and applications

Germany VAG valve company's RKV, RKV RIKO piston flow control valve. Piston Flow Regulators Unlike butterfly and gate valves, which are used only for pipeline shut-off, piston valves are valves that fulfill a variety of special regulatory requirements. The adjustment function is based on a piston-like cylinder in the valve cavity for axial movement to achieve its stroke and the direction of the water flow is consistent. Flow from the axial arc into the shell, piston valve spool for the axis of symmetry, the fluid flow does not produce turbulence. The change of the area of ​​the flow passage is achieved by a piston moving linearly along the pipe axis. No matter where the piston is, the water in the valve chamber no matter the piston moves to any position, regardless of the location of the valve cavity of the flow cross-section are annular, at the exit to the axis of contraction, so as to achieve the best anti-cavitation, to avoid Cavitation that may occur due to throttling damages valves and pipes. Piston valve body designed as a whole, with high flow capacity, opening and flow into a linear relationship, can effectively avoid cavitation and vibration. The inner shell has a streamlined guide rib connected with the shell, the stainless steel piston is guided reliably and slides to prevent tilting or poor running. The upstream face of the inner shell is spherical, forming a gradual change of water flow. The piston is operated by a crank rod mounted in the shell. Piston valve metal and metal and rubber double seal, to achieve two-way bubble-level seal. So to achieve long life sealing system, close tight. Due to the special structure of the piston valve, the valve's water-passing characteristics can be adjusted by the type of the outlet part of the outlet of the valve (replaceable outlet part) according to the operating conditions so as to meet the requirements of different working conditions and achieve the best The transfer effect. There are four types of outlet-regulated components: The first E-type, with straight straightening and sudden enlargement of the structure along the downstream cross-section, eliminates cavitation damage. For flow control, high pressure, back pressure large occasions, and cut straight, cross-section suddenly enlarged structure can reduce the cavitation effect. The second S-type, with its closed guide part having a slotted sleeve. For flow control, high pressure differential adjustment and sufficient back pressure large occasions, its regulation and fluid state match, you can achieve better results. The third F-type, the body part of the outlet has a short diffuser effect, suitable for regulating and opening and closing occasions, play the role of switch. Opening and closing head loss is very small, fully open when the resistance is small. The fourth type of LH or SZ, the piston-closed guide element in the valve chamber is fitted with a porous ring with cavitation protection for adjustment, cavitation prevention, high differential pressure, small backpressure (reservoir inlet) , It's flow control features and operating conditions require the best match, so as to achieve the elimination of cavitation effect. VAG piston valve can be used as a relief valve and explosion-proof pipe valve in the water diversion, VAG piston valve LH type, E type can be used as a liquid level or pressure regulating valve during storage, VAG piston valve LH, S type Can be used as a flow control valve, type E, LH or SZ can be used as a drain valve or pipe filling valve, sewage, water treatment VAG piston valve can be used as a pump start protection valve, or with special regulating outlet components , Can also be used in water treatment plant flow control valve, E-type piston valve can also be used as a sewage treatment plant gas control valve on the water VAG piston valve according to liquid conditions using different outlet components for pressure / flow control Valves, such as pipe network pressure balance.

Car Air Purifier

The function of Car Air Purifier:

Car air purifier refers to vehicle air purifier. It refers to air purification equipment specially used to purify PM2.5, toxic and harmful gases (formaldehyde, benzene series, TVOC, etc.), peculiar smell, bacteria and viruses in the air in the vehicle. Vehicle mounted purifier is also called vehicle purifier or vehicle mounted air purifier. It is usually composed of high-voltage generation circuit, anion generator, breeze fan, air filter and other systems.

Advantages of Car air purifier

Efficient purification mode
Get rid of the filter screen of desktop Air Purifier - passive purification mode, and the active purification mode of ion technology shows its efficient purification effect. The traditional passive purification method of combining multiple filters to firmly absorb dust can not purify every corner of the car, but ion technology can solve this problem. Spraying ions from the on-board air purifier will reach every corner of the car and play a complete purification effect.

High strength sterilization
High quality ion technology is needed to achieve high-strength sterilization. General vehicle air purifiers will adopt silver ion purification technology and low-temperature plasma technology; Some advanced will use negative ion technology and photocatalyst technology; The more advanced will use the net ion group technology.

Fashionable appearance, gifts
Nowadays, the popular style of small household appliances is no longer elegant European and American style, but simple and fashionable Japanese style. The same is true of car air purifiers. Pure color and fashionable appearance are more popular. Modern people who pay attention to practicality pay more and more attention to vehicle air purifier when choosing gifts. Whether it is a new house gift, wedding gift or business gift, the car air purifier has become the first choice.

Authoritative certification, sales assurance and perfect after-sales service
An on-board air purifier can obtain a number of international authoritative certifications and professional experimental verification, which is the recognition of its safety and purification ability by professional departments; The sales volume is the trust guarantee of the customer group; In addition, the perfect after-sales service can generally reach the level of national joint guarantee and door-to-door warranty, so it is called the perfect on-board air purifier
