1. Product introduction
Application and structural characteristics
1. Use:
Check valves are used in industrial pipelines as a device to prevent media counterflow. By selecting different materials, it can be used for water, steam, oil, and nitrate
Quality.
2. Structural features:
Cast steel swing check valve adopts bolted disc, single disc swing structure, is an international common structure,
3. Valve seat:
There are several types of seats for different pressures and specifications:
a: The valve seat ring is threaded or welded to the valve body. The threaded connection is easy to maintain and replace the valve seat.
b: surfacing the sealing material directly on the valve body.
c: For stainless steel valves, the sealing surface of the valve seat is generally processed directly on the valve body
4. Middle flange gasket:
The sealing of the middle channel is ensured by the use of metal wound graphite filled with a flat, convex or gasket or octagonal ring pad with the inner ring.
Iii. Storage
1. The valve should be stored in a dry and ventilated room.
2. During the storage period, the opening and closing parts should be in the open position, the channel should be tightly covered by the cover, and take anti-rust measures.
3. Long-term placement should be regularly checked on the sealing surface and other parts, remove dirt and dust, and wipe new anti-rust oil.
Four, installation
1. When the check valve is transported to the installation site, the valve disc should be opened and completely fixed before it can be transported.
2. When installing, it should be intended to ensure that the flow of the medium is consistent with the direction of the arrow on the valve body.
3. The valve should be installed horizontally on the pipeline, the valve body can not bear the weight of the pipeline, and the necessary support should be added to the large-caliber valve.
4. Before installation, the parameters on the nameplate must be carefully checked to meet the requirements of the pipeline.
5. Use
1. Do not knock the valve during use.
2. Pay attention to the cleanliness of the medium during use, and pay attention to the viscosity of the pipeline medium should not be too large.
3. It is normal to have a slight "water hammer" during use.
