The valve can be used for opening and closing on pipelines and equipment with non corrosive medium, and generally it is not used for throttling.
The main body is made of grey cast iron, and the applicable temperature for copper sealing is -10 ℃ ~ 200 ℃; Applicable medium: water and steam.
The applicable temperature of iron seal is -10 ℃ ~ 100 ℃; Applicable medium: general oil.
1. simple shape, good manufacturability, wide application range and easy installation.
2. the structure is reasonable and compact, the volume is small, and the closing piece (RAM) adopts wedge structure, which can automatically compensate the deformation of the valve body caused by abnormal load or temperature during operation, and the sealing is safe and reliable.
3. the medium can flow in any direction from both sides of the gate valve to achieve the purpose of connection or disconnection.
1. the valve is flange connected;
2. the valve is composed of valve body, bonnet, gate, valve rod, hand wheel and other parts. By rotating the hand wheel, the
The valve rod rises or falls, thus driving the ram to rise or fall, making a linear displacement perpendicular to the fluid,
To achieve the purpose of opening and closing.
| Possible failure | Cause of failure | Elimination method |
| Leakage of sealing surface | 1. dirt and other objects are mixed between sealing surfaces. | 1 clean the dirt on the sealing surface. |
| 2. the sealing surface is damaged. | 2. correct the sealing surface again. | |
| Packing leakage | 1. the packing cover is not compacted. | 1. tighten the nuts evenly to compress the packing. |
| 2. insufficient packing. | 2. add filler. | |
| 3. packing failure. | 3. replace with new packing. | |
| Leakage of flange connection sealing surface | 1. flange bolts are not tightened or the tightness is uneven | 1. tighten the bolts evenly and symmetrically. |
| 2. the connection sealing surface is damaged | 2. refinish the flange sealing surface. |
