Linear electric flange ball valve:
one The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in vacuum systems.

Detailed introduction

First, linear electric flange gate valve use

Ball valve in oil, natural gas, coal and ore mining, refining processing and pipeline transportation system; In the production of chemical products, pharmaceuticals and food; In hydroelectric, thermal and nuclear power generation systems; In water supply and drainage, heat supply, and gas supply systems of urban and industrial enterprises; In the drainage and irrigation system of farmland; It has been widely used in the gold production system, and is an important mechanical product closely related to production construction, national defense construction and people's life. Ball valve closed in all kinds of pipeline systems are used to cut off or connect the medium flow, so that the medium is transported to various points in accordance with the predetermined program.

Two, linear electric flange gate valve features and advantages

1, the manual part can be made of steel plate pressing handle or stainless steel casting handle. The handle is provided with a limit structure to set a limit at the opening and closing positions of the valve. When the valve is used on the key device, the limit block is provided with a lock hole to lock the switch position to avoid misoperation. The handle is clearly marked on and off.

2, the valve stem adopts A182F (1Cr13) integral forging and modulation treatment, the hardness reaches HB220 ~ 250. The valve stem is connected with the handle by a flat key or spline or square, which is versatile and easy to disassemble and assemble. The valve stem is provided with an anti-blowout structure.

3. The packing of the valve is braided, flexible graphite sealing ring or tetrafluoroene sealing ring, so that the valve stem can achieve reliable sealing under certain lubrication conditions.

4, according to the need, the ball valve can be designed into an anti-static structure, in the sphere and the stem, the stem and the valve body between the conductive spring, to avoid electrostatic ignition ignition flammable substances, to ensure system safety.

5. Various forms of sealing. According to different working conditions can choose soft seal, hard seal, fire valve seat and other structures; The floating ball form is below DN150 and the fixed ball form is below DN200.

6, the ball valve seat can be equipped with an auxiliary sealing structure, in the seat and stem parts of the grease valve, emergency can be temporarily sealed, and according to the need to extend the valve stem to suitable for buried laying places

Third, linear electric flange gate valve electric installation working environment and main technical parameters

1 Power supply: three-phase AC motor, 380V (special order 660V or 220V 24V),

50Hz (60Hz for special orders);

The control line is 220V, 50Hz (60Hz for special orders);

Remote control is 24VDC.

2. Working environment:

2.1 Ambient temperature: -20~+60℃ (-40~+80℃ for special orders).

2.2 Relative humidity: ≤90% (25℃).

2.3 Protection type: ordinary type and outdoor type are used in places without inflammable, explosive and non-corrosive media, of which ordinary type is used indoors; There are two kinds of flameproof products: dⅠ and dⅡBT4. dⅠ is suitable for non-mining working face of coal mine. dⅡBT4 is used in factories, suitable for explosive gas mixtures in the environment of Ⅱ, ⅱB class T1~T4 groups. (See GB3836.1 for details)

2.4 Protection level: IP65 for outdoor and explosion-proof types (IP67 for special orders).

3 Working time: short time 15 minutes (special order 30 minutes).
