First, product [BQ71F on clip type insulation ball valve] detailed information:

Product Name: clip type jacket insulation ball valve

Product model: Q71F

Product Description: BQ71F wafer type jacket insulation valve has good heat insulation properties, in addition to reducing insulation valve, the valve diameter and the diameter of one to medium linear flow resistance is small, can effectively reduce the heat loss of the medium in pipelines, therefore, the liquid medium high viscosity, easy to solidification with excellent performance. In addition to the two piece insulation ball valve, the whole body adopts integral jacket design, more uniform insulation, cold protection. The jacket and the outer side of the valve are welded with the jacket nozzle, allowing the maximum pressure of steam or cold water to be 1MPa. BQ71F clip type insulation ball valve, also known as BQ71F clip type jacket insulation ball valve, due to the use of steam jacket insulation, so even if the external temperature below zero degrees, the valve is still flexible operation, to ensure that the oil pipeline can be opened and closed. The advantage is that other control valves do not have, it is the ideal control valve of heavy oil pipeline.

BQ71F connection mode of clip type insulation ball valve jacket:

1. Internal thread connection is optional. DN15~DN20G3/8, DN25~DN150G1/2, DN200 above G3/4.

2, flange connection can be selected. DN15~DN50 is 15 flanges, DN65~DN150 is 20 flanges, and DN200 is more than 25 flanges.

Structural features of clip type insulation ball valve two and BQ71F:

Heat preservation ball valve, also known as jacketed insulation ball valve, is based on the ball valve welding metal jacket, used for injection of steam or other insulation, cold medium, to ensure that the medium in the valve can work properly. Insulation ball valve structure according to different, there is a whole two piece ball valve, insulation insulation ball valve, clamp type insulation ball valve structure, thermal insulation ball valve with good cooling characteristics, with the diameter of the valve diameter and, at the same time can effectively reduce the heat loss of pipeline media. The working principle of BQ71F on clip type heat preservation ball valve is to make the valve unblocked or blocked by rotary valve. Ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and sphere often closed state, not easy to be medium erosion, widely used in various industries. It is mainly used in petroleum, chemical, metallurgical, pharmaceutical, food and other systems, to transport high viscosity medium which will solidify at normal temperature.

BQ71F clip type insulation ball valve is mainly used in the pipeline to do cutting, distribution and change the flow direction of the medium. Ball valve is widely used in recent years, a new type of valve, it has the following advantages:
1., the fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2. simple structure, small size, light weight.
3., close and reliable, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum system has been widely used.
4. easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5. convenient maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. in the full open or full closed, the ball and seat sealing surface and media isolation, the media through, will not cause the valve sealing surface erosion.
7., a wide range of applications, diameter from a few millimeters, large to several meters, from high vacuum, high pressure can be applied. When the ball rotates 90 degrees, all the spherical surfaces should be presented at the inlet and outlet,

Matters needing attention in installation and maintenance:
1. keep the rotating position of the valve handle.
2. can not be used as throttling.
The ball valve of 3 belt drive mechanism should be installed upright.
