For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of double sealing lift valve, can make high-temperature systems flue close rear without leaking, ensure the normal use of the sack cleaner of the normal work of steam generator system.
The technical solution of the utility model is achieved in that
A kind of double sealing lift valve, comprise valve body, valve plate and the lifting driving device being connected with valve plate, described valve inner is provided with upper strata valve seat and lower floor's valve seat, on described upper strata valve seat and described lower floor valve seat, be provided with Stamping Steel Ribbon, and, lower floor's valve plate that described valve plate comprises the upper strata valve plate that matches with described upper strata valve seat and matches with described lower floor valve seat, is provided with holddown spring between described upper strata valve plate and described lower floor valve plate.
Further, described valve plate is connected with described lifting driving device by promoting guide rod.
Further, described double sealing lift valve also comprises: guiding pole socket, described guiding pole socket is arranged at described valve inner, and is connected with described lifting guide rod.
Further, described guiding pole socket and described lifting guide rod are connected and comprise: on described guiding pole socket, be provided with groove, the up and down motion in described groove of described lifting guide rod.
Further, between described guiding pole socket and described lifting guide rod, be provided with seal ring.
Preferably, the area of described upper strata valve plate is greater than the area of described lower floor valve plate.
Preferably, the shape of described upper strata valve plate comprises circle.
Preferably, the shape of described lower floor valve plate comprises circle.
The utility model by arranging double-deck valve seat in valve body, and configure corresponding double-deck valve plate, and between double-deck valve plate, holddown spring is set, provide repulsion by holddown spring for double-deck valve plate, thereby effective sealing that has ensured poppet valve, prevent that valve seat from occurring because distortion or grieshoch cause the problem that sealing reduces, and then effectively raise the Security of dust pelletizing system, can effectively ensure the normal work of steam generator system.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation during according to the utility model embodiment's double sealing lift valve open mode;
Fig. 2 is the structural representation during according to the utility model embodiment's double sealing lift valve closed condition.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope that the utility model is protected.
According to embodiment of the present utility model, provide a kind of double sealing lift valve.
As shown in Fig. 1 to 2, comprise valve body 1, valve plate 2 and the lifting driving device 3 being connected with valve plate 2 according to the utility model embodiment's double sealing lift valve, described valve body 1 inside is provided with upper strata valve seat 4 and lower floor's valve seat 5, on described upper strata valve seat 4 and described lower floor valve seat 5, be provided with Stamping Steel Ribbon, and, lower floor's valve plate 202 that described valve plate 2 comprises the upper strata valve plate 201 that matches with described upper strata valve seat 4 and matches with described lower floor valve seat 5, is provided with holddown spring 6 between described upper strata valve plate 201 and described lower floor valve plate 202.
In the time of practical application, in order to make poppet valve there is good guide function, can connect valve plate 2 and lifting driving device 3 by lifting guide rod 7 is set, simultaneously in order to make poppet valve there is good locating function, guiding pole socket 8 also can be set in the inside of valve body 1, and the pole socket 8 that makes to lead is connected with lifting guide rod 7.
And for being connected between guiding pole socket 8 and lifting guide rod 7, can on guiding pole socket 8, groove be set, and promote guide rod 7 up and down motion in described groove, wherein, the gap promoting between guide rod 7 and groove is preferably 0.5mm.
Certainly,, for the sealing of poppet valve is further provided, also can and promotes between guide rod 7 at guiding pole socket 8 and be provided with seal ring.
In addition, in the time of practical application, the area of upper strata valve plate 201 can be set to be greater than the area of lower floor's valve plate 202, the shape of upper strata valve 201 plates can be set to circle simultaneously, the shape of lower floor's valve plate 202 can arrange circle, certainly,, in the time of practical application, area and the shape of valve plate 2 also can be set according to actual needs.
In addition, in the time of practical application, for adapting to the application of large-scale wind pipeline, multiple double sealing lift valves one-tenth in parallel combination brake switch and proporting can be used.
When concrete use, for example, drive valve plate 2 to move up and down by the lifting driving device 3 (, electric pushrod, cylinder unit or electric actuator) of top.In the time of valve closing, double-deck valve plate 2 moves downward, and first lower floor's valve plate 202 contact with lower floor valve seat 5 Stamping Steel Ribbons, and contact afterwards holddown spring 8 starts stressed, in the time that holddown spring 6 is compressed to certain stroke, upper strata sealing plate 201 contacts compression with the Stamping Steel Ribbon of upper strata valve seat 4.When impacting force is applied to certain pressure, lifting driving device 3 stop motion pressurizes, at this moment upper strata valve plate 201 leans on the pressure of lifting driving device 3, valve plate 2 and Stamping Steel Ribbon close contact.Lower floor's valve plate 202 and the pressure close contact of lower floor's valve seat 5 by holddown spring 6.Ensured the sealing effect of valve, impelling leak-down rate is 0.
In addition,, in the time of concrete use, owing to being provided with holddown spring 6 between upper strata valve plate 201 and lower floor's valve plate 202, thereby also effectively compensate amount of deformation that steel structure at high temperature produces and the slow-action amount of lifting driving device.
