The Advantages Of Fixed Ball Valve:

  1.Sealed tight grease injection and rescue: Because the foreign material in the medium or the fire caused the valve seat seal to accidentally fail, the grease injection valve provides the connection with the speed of the grease gun, and the imported pump can write the seal grease to the valve seat quickly and conveniently parts to reduce leakage.

2.With a solid stem seal and low operating torque.

3.Full diameter or reduced diameter: can use full diameter or reduced diameter structure according to demand. Full-diameter valve flow orifice is shared with the inner diameter of the pipeline to facilitate the cleaning of the pipeline.

 

4.The valve stem can be lengthened: according to the needs of installation or operation, the forged steel ball valve stem can be lengthened. The extended stem ball valve is particularly suitable for applications where city gas and other demands are buried in pipelines. Extended stems are sized to customer requirements.

 

5.Sensitive operation: Select valve seats and stem bearings with small friction coefficient and outstanding self-lubrication, greatly reducing the operating torque of the ball valve. As a result, the valve can be operated for a long period of time even without the supply of a sealed grease.

 

 

Fixed Ball Valve Features:

  1.Double clogging and discharge function: The fixed stainless steel ball valve adopts the spring to tighten the float valve seat, regardless of whether the valve is in the fully open or fully closed state, the upstream and downstream side valve seats block the fluid, and the valve body cavity stays through the discharge valve. secretion.

2.Active pressure relief function: the body cavity of the valve to stay in the medium to increase the temperature caused by abnormal pressure, do not need to go through the safety valve, but only rely on the valve seat function can be actively pressure relief, which to ensure the safety of the valve in the delivery of liquid media Very important.

3.Fire safety structure: the gost ball valves have a fire safety function, its planning, manufacturing are subject to API 607 and API 6FA specifications request.

City Water Supply System Valve Operation Management

The valve is used as an important control equipment signal of the pipeline network. The butterfly valve is not operated frequently. To ensure that the valve is opened and closed at a critical moment, in addition to the proper valve quality and type selection, the valve application problem must be solved from the source; Installation, meticulous construction; also need to pay attention to the daily maintenance of the valve and maintenance, maintenance.

Good operation management is mainly reflected in the following aspects:

1. The technical data of the gost gate valve is complete and complete. 

2. The valve operation management quality requirements include that the valve should be closed tightly or basically tightly; the valve packing should not leak; the valve should be opened and closed lightly and the instructions should be in good condition.

3. Valve well management

Valve well daily management includes valve well masonry conforming to the design requirements; the well cover is intact and the road surface is intact; the hole position of the valve is accurate; there is no debris and sewage in the well; and the valve surface is free of rust spots.

4.Apply scientific and technological means to improve management.

 

Application Of Hard Seal Butterfly Valve

  1. The butterfly valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with more and more tight sealing function.

2. The seal ring is made of stainless steel. It has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance under low temperature and high temperature conditions, and has the characteristics of corrosion resistance and long service life.

3. The plate sealing surface using surfacing cobalt-based carbide, sealing surface wear resistance, long service life.

4. The large size butterfly board adopts truss structure, high strength, large flow area, and small flow resistance.

5. The valve has a two-way sealing function, the installation is not limited by the flow of the media, but also by the location of space, can be installed in any direction.

6. The drive device can be multi-station (rotated 90 ° or 180 °) installation, user-friendly. Flanged center line butterfly valve is a nice one.

 

Application Of Soft Seal Butterfly Valve

  The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully opened.

The characteristics of the new high-life 20K butterfly valve and the use of the butterfly valve in the use process are generally horizontal. Soft seal butterfly valve can be divided into flange type soft seal butterfly valve,wafer and lug type butterfly valve and welded soft seal butterfly valve according to the connection mode.
