Description
Technical field
The utility model relates to field of combustion technology, relates in particular to a kind of heat-accumulation combustor selector valve.
Background technique
Regenerative Combustion Technology is an industry heating/heat treatment furnace field important energy saving technology, and all the other heat recovery rates can reach 80%.For Regenerative Combustion Technology, adopt heat-storage type fume residual heat recovering device mostly, alternately switch air or gaseous fuel and flue gas; Make it the heat retainer of flowing through; Can reclaim the waste heat of high-temperature flue gas to the full extent, temperature of exhaust fume can drop to below 180 ℃, can combustion-supporting medium or gaseous fuel be preheating to more than 1000 ℃; Form the novel flame type different, and make through reversing combustion that temperature distribution more becomes even in the stove with traditional flame.In the heat-storage type fume residual heat recovering device, selector valve is one of key equipment.Selector valve generally includes valve body, valve gap, the live axle that is connected with drive unit, spool, and said valve gap is located at the valve body upper end, and said spool is located on the valve body through live axle rotationally, thereby changes the flow direction of air-flow through the position that changes spool.Spool is general to adopt high temperature resistant, corrosion resistant special rubber materials sealing, but its easy ageing distortion even come off in hot environment, sealing is poor, and working life is short.And adopt the sealing means of tight contact-type, and because commutating frequency is high, friction is frequent, and easy abrasion can cause sealing poor equally, and working life is short, also influences commutating speed simultaneously.
The model utility content
Therefore, to above-mentioned problem, the utility model proposes a kind of simple in structure, good sealing effect, long service life, the fast heat-accumulation combustor selector valve of commutating speed.
For realizing above-mentioned purpose; The utility model has adopted following technological scheme: a kind of heat-accumulation combustor selector valve; Comprise valve body, valve gap, the live axle that is connected with drive unit, spool; Said valve body is a circular cylinder body, and said valve gap is located at the valve body upper end, and said spool is located on the valve body through live axle rotationally; The air flue interface that said body wall is provided with the thermal accumulator interface that is communicated with heat-accumulation combustor that is positioned at same horizontal plane, the flue interface that is communicated with flue, is communicated with air flue; Said thermal accumulator interface, flue interface, air flue interface are communicated with valve body respectively, and said flue interface, air flue interface are symmetrically set in the both sides of thermal accumulator interface, are provided with the passage that is communicated with thermal accumulator interface and flue interface in the said spool; The breach that is provided with respect to an end of passage on the said spool, the sidewall of said spool except that the breach end is infinitely closely near valve interior wall.
Further, evenly be provided with some cellular holes on the said spool outer wall.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the existing selector valve sealing means that adopt tight contact-type more; Mostly sealing material is high temperature resistant, corrosion resistant special rubber; But under high temperature and quick working environment easy ageing, be out of shape and come off, sealing is poor, inefficiency, working life are short; This heat-accumulation combustor selector valve is simple in structure, and is not easy to wear, is difficult for wearing out, is out of shape, comes off, good sealing effect, high working efficiency, long service life.

Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
With reference to figure 1,2,3,4,5; A kind of heat-accumulation combustor selector valve of the utility model; Comprise valve body 1, valve gap 2, the live axle 3 that is connected with drive unit, spool 4, said valve body 1 is a circular cylinder body, and said valve gap 2 is located at valve body 1 upper end; Said spool 4 is located on the valve body 1 through live axle 3 rotationally; The air flue interface 7 that said valve body 1 sidewall is provided with the thermal accumulator interface 5 that is communicated with heat-accumulation combustor that is positioned at same horizontal plane, the flue interface 6 that is communicated with flue, is communicated with air flue, said thermal accumulator interface 5, flue interface 6, air flue interface 7 are communicated with valve body 1 respectively, and said flue interface 6, air flue interface 7 are symmetrically set in the both sides of thermal accumulator interface 5; Be provided with the passage 41 that is communicated with thermal accumulator interface 5 and flue interface 6 in the said spool 4; The breach 42 that is provided with respect to an end of passage 41 on the said spool 4, the sidewall of said spool 4 except that breach 42 ends evenly is provided with some cellular holes 43 infinitely closely near valve body 1 madial wall on said spool 4 sidewalls.
In use there are three kinds of states in the utility model embodiment: like Fig. 3, heat-accumulation combustor is communicated with air or fuel gas; Like Fig. 4, heat-accumulation combustor is communicated with flue; Like Fig. 5, thermal accumulator interface, flue interface, air flue interface are not communicated with mutually.The effect of the live axle through connecting drive unit, the position of spool constantly changes, the conversion of several states more than the realization, thus realize the frequent switching of air (or fuel gas) and flue gas, realize that heat retainer reclaims the limit of fume afterheat.
The existing selector valve sealing means that adopt tight contact-type more, mostly sealing material is high temperature resistant, corrosion resistant special rubber, but under high temperature and quick working environment easy ageing, be out of shape and come off, sealing is poor, inefficiency, working life are short; This heat-accumulation combustor selector valve is simple in structure, and is not easy to wear, is difficult for wearing out, is out of shape, comes off, good sealing effect, high working efficiency, long service life.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
