1.Top entry eccentric semi-ball valve Product Description:

Top coat eccentric hemispherical valve is suitable for sewage treatment, pulp, alumina, urban heating and heating, oil, natural gas, liquid two phases of mixed or easily chemical crystallization of media and other requirements of the occasion is strictly prohibited. Can be used instead of: General valves, special valves for the oil and chemical industry, special valves for gas, special valves for slurry, special valves for pulverized coal ash and the like.

Overbalance hemisphere eccentric eccentric structure principle, through the transmission mechanism to achieve the purpose of tightness, regulation, closure. The double-eccentric structure ball valve is hidden in the valve cavity when the ball valve is opened, and the flow surface is large. When the valve is closed, the spherical surface of the valve core gradually advances along the valve seat, and has a shearing function so as to effectively remove fouling obstacles and achieve reliable sealing.
 

2.Top entry eccentric semi-ball valve works:

This series of ball valve is the crystallization of the traditional ball valve spiritual changes, it is fixed to the metal ball crown on the eccentric ball, eccentric rotation of the crankshaft by 90 degrees to achieve the valve opening and closing, and metal ball sealing surface contact with the metal seat in the Axial and radial float to compensate for the ball and valve seat with the valve. Simple and reliable structure and effective sealing method makes it not only can replace the gate valve, but also can be used in non-useable system. It can be widely used in petroleum, chemical, power and metallurgy industries. Its core technology is the first in China, and it has unique design and novel structure. Its structure adopts the principle of eccentric tightness to achieve the purpose of locking, adjusting and closing through the transmission mechanism. The sealing pair is a hard-surface contact seal of a metal surface ring belt. When the double-eccentric structure is opened, the valve core is located in a Tibetan ball room, The valve is not washed, the valve core is not washed off when it is closed, and when the valve core is opened, the valve core gradually advances along the valve seat to effectively remove scaling problems and achieve reliable sealing. It is particularly effective for mixed flow delivery of two-phase flow-prone fouling solids.
 

3.Loading eccentric hemisphere valve Features:

1, sealed tightly, delivering zero harmful gas leakage.

2, the valve hemisphere with bimetallic, base metal surfacing on different alloys, the valve seat is also the corresponding surfacing by special treatment, the sealing surface into anti-corrosion, wear-resistant, high strength and other types to meet the needs of different occasions .

3, the seal of the deputy left the amount of compensation valve, when the valve to do wear, turning off a little while, any reliable sealing, extending the service life. In addition, the user will squeeze the nut twist off, seat adjustment or replacement valve is still available, to avoid the failure of the valve seal, the entire scrap defects.

4, the structure of the principle of eccentric tight tight through the transmission mechanism to achieve the purpose of regulating, closing, sealing pair is a metal surface with hard-surface contact seal, the double-eccentric structure in the open when the spool is located in possession of the ball room, large flow cross-section , And the valve is not washed, the valve core is not washed off when closed, open when the valve core gradual progress along the valve seat, the effective removal of scaling obstacles to achieve a reliable seal. It is particularly effective for mixed flow delivery of two-phase flow-prone fouling solids.
