Product Description

The model of QBQ**1 is a worm-gear actuator, flanged connection and straight through valve. It can be classed 4 different types according to its difficult sealing materials (W, H, M,M1);

A Type of QBQ**1W valve is suitable for water, steam, sewage, pulp etc.

B Type of QBQ**1H gas special valve is used to petrochemical industries. It is suitable for various kinds of nature gas (oil field gas and coal gas), coke furnace gas, water gas, and liquefied gas in the petrochemical industries which are featured with high pressure, flammability, explosivity, and causticity. It can also be used for some process flow which includes gas containing impurity or tar or easy to scale. Good sealing performance and anticorrosive capability are suitable for the distribution of coke furnace gas, water gas and city nature gas in the pipelines and pressurization stations. This type of valve exceeds ball valve and gate valve. It is easy to close and has a good sealing performance. The fouling on the surface of the valve parts can be easily erased, so that it is anticorrosive, anti-high-temperature and better than ball vale.

C Type of QBQ**1M 

A special slurry valve is used on the pipeline which may have influence on the pipeline flow as the medium may be easy to precipitate, scale, or crystallize and separate out or may contain impurities. It is easy to open and can be closed smoothly after breaking the fouling. It also has a good sealing performance and can be widely used in metallurgy, chemical industries, ash transportation and so on.

D Type QBQ**1M1

Valve is specially used for coal powder, spraying and alumina powder transportation. It is a perfect equipment to control dusty gas, fluid containing large particle, two-phase fluids and powder solid medium. It is applied to transport powder spraying, milling system and dust precipitation system. This kind of valve has the following features:

a)        Straight through. It is made for single direction sealing and an eccentric structure, especially suitable for the two-phase fluid medium in coal powder spraying and alumina conveying system. The valve core deviates from seat when opening, making it impossible for the flow to be jammed by accumulated ash.

b)        Easy open and close. There is no contact between the valve core and the valve seat when opening, therefore causing little torque and free turning. While the function of squeezing and cutting between the semi-sphere and seat removes the fouling and adhesives on the sealing surfaces when closing, therefore assuring a tight and reliable sealing.

c)        The eccentric structure of the sealing surface enables an automatic repairing of the spherical wearing. This results in a good sealing, long working life, and safety and reliability. No leakage will occur due to wearing even after a long period of service.

d)        The valve is a kind of hard sealing structure. The material of the sealing set is anti-abrasive alloy of Cr-Mo-V. It is made by special treatment. The valve core apart from direct flushing, therefore lessening abrasive effect and lengthening the service life.
