Abstract
The utility model discloses a water-cooling heat-insulation hot-blast valve, comprising a valve plate, a valve cap 2 and a valve seat 1, wherein, the valve seat 1 is composed of a water-cooling seat ring 5, a seat ring outer shell hollow cavity 3, a refractory material protective jacket 4, etc.; the inner part of the valve cap 2 is bundled by refractory materials; the water cooling seat ring 5 is lined with the refractory material protective jacket 4; the section of the refractory material protective jacket 4 forms a square or an arc to increase the thickness of the refractory materials, so that the service life of the hot-blast valve is enhanced. The seat ring and the outer shell of the hot blast valve use proper cavity size in cooling, and use a cascade water-feeding mode to control water flow speed in a certain range for saving cooling water consumption. The utility model can be used for cutting the conveying of high temperature gas.
Description
The utility model relates to a kind of water-cooled adiabatic heat air-valve.
Existing hot-blast valve mostly is the adiabatic heat air-valve of whole-water-cooling.It has following shortcoming:
What 1. the cooling of the shell of hot-blast valve seat ring was adopted is big cavity, and the cooling water flow velocity is low, heat exchanging function is little;
2. the refractory material of hot-blast valve seat ring protection is oblique protecting jacket, because refractory material protecting jacket thin thickness, thereby influences working life of hot-blast valve.
The purpose of this utility model is that a kind of hot-blast valve of design satisfies following requirement: 1. the cooling of the shell of hot-blast valve seat ring is adopted suitable cavity tandem water supply and controlled water flow speed within the specific limits, with using water wisely.2. change the shape of the refractory material protecting jacket of seat ring, to improve the working life of hot-blast valve.
For achieving the above object, adopted following design proposal, hot-blast valve comprises valve plate, bonnet and valve seat.Valve seat is made up of institutes such as water-cooled seat ring and seat ring cavity pocket of outer cover.Bonnet is above valve seat, and the bonnet internal surface is wrapped up with refractory material.Water-cooled seat ring lining is with the refractory material protecting jacket, and the section of protecting jacket is square or arc.The sectional dimension of cavity reduces 1/2 than conventional cross-section size, and water velocity is accelerated, and has improved heat transfer condition, and adopts tandem to supply water, and has reduced water consumption.
The utility model has been compared following advantage with existing whole-water-cooling hot-blast valve:
1. the reducing and adopt tandem to supply water of water-cooled seat ring, seat ring shell water-cooled cavity can reduce water consumption.
2. the refractory material protecting jacket changes into square or arc by oblique, has increased refractory thickness, therefore the working life that helps improving hot-blast valve.
The utility model is described in further detail below in conjunction with accompanying drawing.
The front view of Fig. 1 hot-blast valve
The side view of Fig. 2 hot-blast valve
Above valve seat 1, be provided with bonnet 2, in valve seat 1, be provided with water-cooled cavity 3 and square or arc protecting jacket 4, also be provided with water-cooled seat ring 5.Bonnet 2 inner faces are cancelled water cooling with the adiabatic wrapping of refractory material.All passing to the tandem cooling water in cavity 3 and the seat ring 5 cools off.Be that cooling water is discharged after water-cooled seat ring 5 enters 3 circulations of seat ring cavity pocket of outer cover.
The utility model can be used for the cut-out in the high-temperature gas conveying, is≤1300 ℃ hot blast break-make as temperature.
