Comparative advantages of full-function ultra-light regulating valve and regulating valve
CLICLS:563
Good regulation function
The regulating function is one of the main functions of the regulating valve, manifested as (1) flow characteristics; ② Adjustable ratio R; (3) small opening performance; (4) flow coefficient; ⑤ Adjust the speed. Full-function ultra-light regulating valve R=100, so that the small opening adjustability is good; Kv value is large, is 2 ~ 3 times of single and double seat valve, sleeve valve.
Cut off function good
The cut-off function reflects the intrinsic quality of the valve. Straight stroke valve standard leakage rate is usually 10 ~ 10; The standard leakage rate of the full-function ultra-light regulating valve is 10, 100 ~ 1000 times higher than the single-double seat valve and sleeve valve.
Overcome large pressure differential
To overcome the differential pressure function is the premise of cutting off, which is inseparable from cutting off function. Two-seat valve allows large pressure difference, but large leakage; Single seat valve small leakage, but allow small differential pressure. The full-function ultra-light regulating valve better solves the problem of large pressure difference and small leakage, and the allowable pressure difference can reach PN value.
Good corrosion resistance
Corrosion resistance function to ensure that the valve can resist medium corrosion, erosion, cavitation and other damage, prolong the service life. The full-function ultra-light regulating valve adopts corrosion-resistant and erosion-resistant materials and preventive measures, which has better corrosion resistance.
Good blocking function
Good blocking function can effectively ensure the normal operation of the valve in unclean media occasions. According to the principle of fluid mechanics development and design of the full function of ultra-light valve, with simple flow, less dead zone vortex, medium straight not easy settlement, good self-cleaning function, has become the high viscosity, suspension, pulp, thick pulp, containing particles and other unclean media applications of the preferred products.
High compressive strength
Pressure function is the safety assurance of the valve. The body structure of the full-function ultra-light valve is single-piece integrated structure, which improves the structural integrity of the pressure limit and improves the pressure strength. High pressure using forged structure, further improve the pressure strength of the valve body, pressure strength can reach more than 32MPa.
Good temperature resistance
Temperature resistance function is the guarantee that the valve ADAPTS to different temperatures. Full-function ultra-light regulating valve adopts rigid and flexible elastic hard seal to solve the core and seat card problems caused by expansion at high temperature; High temperature wear-resistant packing is used to ensure the reliability of stem sealing at high temperature.
Good appearance and light weight
Appearance and weight function reflect the valve miniaturization, light, instrument characteristics. Full-function ultra-light regulating valve adopts integrated valve body structure and appearance optimization design, and matched with a simple and reliable direct connection with the actuator, compact structure, small size, light weight, good appearance. Compared with the traditional leading single seat, double seat, sleeve regulator, the weight of the full-function ultra-light regulator is reduced by 60-80%, and it is 40-60% lighter than CV3000 and fine small regulator. Take DN100 electric valve as an example, the sleeve regulator weighs about 150Kg, and the full-function ultra-light regulator only weighs 40Kg (electronic), 73% lighter.
