Abstract
The invention discloses an ultra high temperature three-way adjusting butterfly valve, which comprises a valve rod, a valve core, a valve seat, a valve body and an operating mechanism, etc. Two media outlet openings and a media inlet opening are arranged on the valve body, a cavity for containing the valve core is formed in the valve body, one end of the valve rod is rotatablely arranged in the valve body and firmly connected with the valve body, and the other end extended out the valve body is connected with the operating mechanism through flat keys. The two media outlet openings and the valve rod are symmetrically arranged, two sealing surfaces of the valve core can be respectively engaged and sealed with the sealing surfaces of the two media outlet openings through the rotating of the valve core, and also can be opened for a certain angle, and thus the media flow quantity adjusting is realized. The invention is characterized in that air cooling channels are arranged in the valve rod, the valve core and the valve seats of the two media outlet openings.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of three-way adjusting butterfly valve.
Background technique
Three-way adjusting butterfly valve is widely used in fields such as petrochemical industry, power station, metallurgy, military project, and its medium of flowing through is a high-temperature gas, and temperature generally is higher than 900 ℃, and pressure is greater than 2.5Mpa.Valve is in the superhigh temperature working state for a long time, if do not take heat insulation cooling method, is cisco unity malfunction.Particularly valve rod, spool, valve seat part are stressed bigger, must remain on a relatively low operating temperature.The present common three-way adjusting butterfly valve type of cooling generally is the water-cooled cooling, and this type of cooling is easy to generate incrustation scale, and the three-way adjusting butterfly valve water cooling, and explosion easily takes place excessive temperature differentials.This in addition type of cooling can be taken away a large amount of heats, and heat-energy losses is bigger.
Summary of the invention
Temperature height when the objective of the invention is to overcome common three-way adjusting butterfly valve valve rod, spool, valve seat work, mechanical strength are low, defectives such as working life is short, a kind of ultra-high temperature three-way adjusting butterfly valve is provided, the valve rod of this valve, spool, valve seat construction compactness, low, the long service life of temperature during work.
In order to realize above purpose, the present invention is by the following technical solutions: a kind of ultra-high temperature three-way adjusting butterfly valve, comprise valve rod, spool, valve seat, valve body, valve gap and operating mechanism etc., valve body is provided with two media outlets and a medium import, form a cavity that holds spool in the valve body, valve rod one end is located in the valve body and with spool rotationally fixedlys connected, the other end stretches out valve body and links to each other with operating mechanism, two media outlets and valve rod are symmetrical arranged, two sealing surfaces of spool are by the rotatably identical and sealing with the sealing surface of seat in two outlet ports respectively of spool, valve rod, all be provided with the cooling channel in the valve seat of spool and two media outlets.
Compared with prior art, beneficial effect of the present invention is: valve seat, spool and valve rod at two media outlets all are provided with the cooling channel, with valve rod, spool and the valve seat of air cooling valve, the operating temperature of valve is reduced, mechanical strength, the working life of valve greatly increase.It is little that the water-cooled cooling range is compared in air cooling, and valve is difficult for explosion.Valve body, valve gap and import and export runner are all filled aluminosilicate fiber cotton heat-insulation and heat-preservation material, make the operating temperature of valve body remain on 100 ℃～110 ℃.
Further describe below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Embodiment
As shown in Figure 1 and Figure 2, the present invention includes valve rod 1, spool 5, valve body 19, bonnet 17, bottom flange 18 and operating mechanism 2.Valve body is provided with two media outlets 3 and 4, two media outlets 3 of a medium import are located at valve rod 1 both sides symmetrically, forms a cavity that holds spool in the valve body.One end of valve rod 1 stretches in the valve body, and the other end stretches out valve body and is connected with operating device 2.Operating device in the present embodiment is an Electric actuator, drives valve rod by Electric actuator and rotates, and can certainly select manual operating device for use, Pneumatic actuator.Spool 5 is high-temperature alloy members, and this spool 5 is enclosed within on the valve rod 1, and with valve rod 1 coaxial rotation.Spool 5 peripheral hardware matcoveredns 7, this protective layer 7 can prevent that insulating layer material from not taken away by air-flow.Be provided with thermal-protective coating 6 between spool 5 outer surfaces and the protective layer.The inwall of valve body and valve gap also is provided with thermal-protective coating and protective layer.
The protective layer evagination of spool 5 both sides forms the adjustment cone 14 that cooperates with two media outlet rotary seals.Valve rod 1 drives spool 5 and rotates, and two cone governors 14 seal or open corresponding two media outlets 3.
Key of the present invention is to be provided with cooling air channel in the valve seat of spool 5, valve rod 1 and two media outlets.Two cooling channels 9,11 back and forth are set in the valve rod 1 vertically with one heart, and valve rod 1 same end is provided with cooling air suction port 8 and air outlet 10.Turning back in the underpart of valve rod in the cooling channel, forms cylindrical runner 16.Cooling channel 9 is communicated with suction port 8, and cooling channel 11 is communicated with air outlet 10.Be provided with the cooling channel 12 of arc in the spool 5, these 12 lower ends, arc cooling channel are communicated with cooling channel 9, and the upper end is communicated with cooling channel 11.The profile phase coupling in the shape of spool cooling channel 12 and spool cross section.Two cooling channels 9 in arc cooling channel 12 in the spool 5 and the valve rod 1 constitute a cooling air return flow line, and cooling air enters from suction port 8, and through cooling channel 9, arc cooling channel 12, cooling channel 11,10 go out from the air outlet successively.Cooling air is taken away valve rod 1 and spool 5 part heats, the operating temperature of valve rod 1, spool 5 is reduced, thereby increase valve rod, spool mechanical strength, life-saving.
Also be provided with cooling channel 13 in the valve seat 15 of two media outlets 3, an end of this cooling channel is communicated with atmosphere, and the other end stretches into valve seat inside.Air enters cooling valve seat in the valve seat.
