Abstract
The utility model relates to a valve plate of a valve with high wind, warm water, and cold and hot air. The utility model mainly comprises a hollow-shaped valve plate core composed of a left and right cover plates and water flow channels inside an inner cavity of the valve plate core, which are divided by water dividing plates. The water flow channels of the utility model are waney helical water flow channels. The valve plate with the structure increases the flow rate of cooling water, and the adhesion and the deposition of impurities in the cooling water can be decreased. Thereby, the heat conducting effect can be strengthened. The service life of the valve plate can be effectively improved, and the failure rate of the valve plate can be reduced.
Description
The utility model discloses a kind of valve plate of high wind-warm syndrome water-cooled Hot-blast valve.
The valve plate of existing and hot-blast valve adapted mainly is made up of the flow channel that water-stop sheet is separated into valve plate core and valve plate in-core chamber that cover plate constitutes, and its flow channel is first-class gauge structure, because the diameter of its flow channel is identical, the flow velocity of the cooling water in it is equal.Thereby easily causing the internal junction trowel used for plastering of flow channel, influence is to the cooling function of valve plate.
The purpose of this utility model is to provide a kind of and reduces adhering to and precipitating of impurity in the cooling water, improves the valve plate of heat conducting high wind-warm syndrome water-cooled Hot-blast valve.
The purpose of this utility model is achieved in that a kind of valve plate of high wind-warm syndrome water-cooled Hot-blast valve, it comprises mainly by left and right cover plate and constitutes the valve plate core of hollow shape and the flow channel that valve plate in-core chamber is separated into by water-stop sheet that flow channel is a waney helical.
The latus rectum of its underpart of latus rectum size of flow channel upper end portion.Center line under the flow channel is lower than valve plate center line 8-12mm.
The technological progress that the utility model is obtained is: flow channel adopts the Different Diameter body, increase the flow velocity of cooling water, has reduced adhering to and precipitating of impurity in the cooling water, thereby has strengthened transmission of heat, has improved the working life of valve plate, has reduced the rate of fault of valve plate.
Be that embodiment further describes the utility model below with the accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
As shown in Figure 1 and Figure 2, constitute the valve plate core of a hollow shape by left and right cover plate 1, be separated to form flow channel 3 by water-stop sheet 2 in its inner chamber, flow channel 3 respectively with intake-outlet 4,5 UNICOMs, flow channel 3 is a waney helical, the outer likeness in form one " incense coil " of its integral body.The latus rectum of the upper end portion of flow channel 3 has promptly formed cooling water path wide at the top and narrow at the bottom greater than the latus rectum of underpart.Relatively read plate center line 10mm under flow channel 3 center lines.Establish many V-type nail hooks in the outside of valve plate core, so that reinforce refractory insulating layer 6.
Claims (3)
1, a kind of valve plate of high wind-warm syndrome water-cooled Hot-blast valve, it mainly comprises by left and right cover plate and constitutes the valve plate core of hollow shape and valve plate in-core chamber by the flow channel that water-stop sheet is separated into, and it is characterized in that flow channel is a waney helical.
2, valve plate according to claim 1 is characterized in that the latus rectum of the latus rectum of said flow channel upper end portion greater than its underpart.
3, valve plate according to claim 1 and 2 is characterized in that the center line under the said flow channel is lower than valve plate center line 8-12mm.
