High-performance double eccentric butterfly valve is a commonly used control valve, which adopts a new type of double eccentric structure, which has the advantages of small flow resistance, good sealing and flexible operation, and is widely used in petrochemical, electric power, metallurgy, fertilizer, pharmaceutical and other industries. This article will introduce the design characteristics, classification, applicable working conditions and summary of high-performance double eccentric butterfly valves in detail.

Prvo, dizajn značajke

The high-performance double ekscentric butterfly valve adopts double ekscentric structure, which is uglavnom composed of valve disc, ventil seat, ležaj, etc. Its design features are as follows:

1. Double ekscentrična struktura: Compared with the Traditional butterfly ventil, the Shaft and brtvljenje surface of the double ekscentric butterfly valve are not on the the same center line, which can Effective reduce the Resistance of The fluid.

2. Višeslojni metal brtvljenje prsten: The višeslojni metal brtvljenje prsten je usvojeno, što ima dobro visoko temperatura otpor, trošenje otpor i korozija otpor, i ensures the brtvljenje performanse of ventil.

3. Adjustable clearance between valve seat and valve disc: The gap between valve seat and valve disc can be adjusted to ensure its tightness and flow control.

4. Ležaj podrška: the use of ležajevi for podrška, the ventil runs more glatko, not easy to leakage, ometanje i ostalo problemi.

II. Klasifikacija

Visoke performanse dvostruko ekscentrično leptir ventili can be podijeljeno into sljedeće kategorije prema prema različite strukture i upotrebe:

1. Intermediate high-performance double eccentric butterfly ventil: The main feature of medium high-performance double ekscentric butterfly valve is good brtvljenje, which can be widely used to transport gas, liquid and solid under various work conditions.

2. Flanged high-performance double eccentric butterfly valve: The main features of flanged high-performance double-eccentric butterfly valve are easy to use, convenient maintenance, and relatively simple disassembly, replacement of bearings, seals and other components.

3. Jacketed high-performance double-ekscentric butterfly ventil: Jacketed high-performance double-ekscentric butterfly valve is uglavnom used in special environments such as high temperatura, high pressure and corosion in chemical procesi.

4. Hranjenje tip visoke performanse dvostruko ekscentrično leptir ventil: Hranjenje tip visoke performanse dvostruko ekscentrično leptir ventil je prikladno za hranjenje ili pražnjenje prigode in metalurgija, farmaceutska i druge industrije.

3. Primjenjivo Radni uvjeti

Visoke performanse dvostruki ekscentrični leptir ventili are široko korišteni in a variety of rad uvjeti, ali različiti materijali i modeli potreba to be selected accord to specific working conditions. In general, it is appropriateable for the following types of working conditions:

1. Niska temperatura i visoka temperatura radni uvjeti: različito brtvljenje materijali i hladno i toplina kompenzacija konstrukcije can be korišteno to adapt to to različito temperatura zahtjevi.

2. High viscosity and high sand content: select high-quality ležajevi and brtvljenje materijali to ensure njih normal rad.

3. Korozivno fluid radni uvjeti: use prikladno ventil tijelo materijali i brtvljenje materijali to ensure to oni mogu withstand korozivne fluidne.

IV. Sažetak

Visoke performanse dvostruko ekscentrično leptir ventil a a vrsta control ventil s mali protok otpor, dobro brtvljenje i fleksibilno rad. It je široko korišteno in petrokemija, električna snaga, metalurgija, gnojivo, farmaceutski i ostalo industrija. Visoke performanse dvostruki ekscentrični leptir ventili različiti modeli i materijali, prikladni za različiti radni uvjeti, s good installation, održavanje i ease of korištenje.
