Gate valve manual gate valve electro-hydraulic gate valve Tianjin MCC spot sales

  Manual gate valves are mostly used for the matching use of unloaders, which are divided into two types: square and round
It has compact structure, wear resistance, small leakage, simple operation, flexible action, labor saving and other characteristics, and can work normally under high temperature, high dust and strong magnetic environment
The mouth shape should be selected according to the shape of the unloader
Welded with high-quality carbon steel, it is widely used in metallurgy, carbon, chemical industry, building materials and other industries
It is mainly used for flue gas regulation and switching in flue gas pipeline system of flue gas purification system The electric gate valve, also known as the electric screw gate valve, is mainly composed of motor, reducer, frame, gate plate, lead screw, chain, gear, controller, etc
the chain or direct connection drive can be used to drive the gate plate up and down to achieve the purpose of opening and closing
Generally, the electric gate valve adopts flange connection, which is divided into two series: square flange and circular flange
There are dozens of specifications and sizes available for selection (the main specifications are dn200× 200~dn800× 800)
It can also be customized according to the installation size requirements The opening and closing part of the electric gate valve is a ram, and the movement direction of the ram is perpendicular to the fluid direction
The electric gate valve can only be fully opened and closed, and cannot be adjusted or throttled
The ram has two sealing surfaces
The two sealing surfaces of the most commonly used Mode RAM valve form a wedge, and the wedge angle varies with the valve parameters
The electric gate valve is a kind of main control equipment for the flow or conveying capacity of powder, granular, granular and small materials
It has the advantages of simple structure, flexible operation, light weight, no jamming and fast cut-off
It is widely used in the dust flow control and management of building materials, metallurgy, mining, electric power, chemical industry, grain and other industries
It is an ideal equipment for controlling the flow of dust materials Installation and description editing: 1 Before the installation of the gate valve, check the valve cavity, sealing surface and other parts, and no dirt or sand is allowed to adhere; 2
bolts at all connecting parts shall be tightened evenly; 3
check that the packing parts shall be compacted to ensure the sealing of the packing and the flexible opening of the ram; 4
before installing the valve, the user must check the valve model, connection size and pay attention to the medium flow direction to ensure the consistency with the valve requirements
5
when installing the valve, the user must reserve the necessary space for valve driving; 6
the wiring of the driving device must be carried out according to the circuit diagram; 7
the gate valve must be maintained regularly and shall not be collided or squeezed at will to avoid affecting the sealing
