Abstract
The utility model relates to a high-temperature gate valve, which belongs to the technical field of high-temperature sealing valves. The high-temperature gate valve comprises a valve body and a valve plate mounted in the valve body, the valve plate is connected with a driving device mounted at the upper end of the valve body via a transmission shaft, a connecting pipe is disposed on the valve body at the position with the valve plate, a circular blind plate is arranged at the upper end of the valve plate, a run-through pore plate is disposed at the lower end of the valve plate, and at least one end of the blind plate is an elastic sealing structure. The high-temperature gate valve has the advantages that the high-temperature gate valve is simple in structure and convenient in operation, and the elastic sealing structure not only is favorable for opening and closing of the valve and avoids jamming the valve plate, but also eliminates attachment gaps due to deformation of the valve plate, avoids leakage of high-temperature media, and has better sealing effect.
Description
Technical field
The utility model relates to a kind of high temperature media flue shut-off means, and especially a kind of high temperature gate valve belongs to the elevated-temperature seal valve technology field.
Background technique
The cut-out mode of understanding the high temperature media flue according to the claimant has two kinds now, what often adopt at present is the gate valve blocking-up, when using gate valve to cut off flue for valve plate and valve body are fitted tightly to reach leak free purpose, valve plate must adopt whole processing, so just cause easily and make difficulty, cost increases.Simultaneously, for further sealing, the blind plate sealing face of valve plate must be with the pore plate by sealing face measure-alike, but so just make the dust that is trapped in the valve body not have Free up Memory, quicken the wearing and tearing of valve body and valve plate, caused leakage easily, and under the high temperature media operating mode, the valve plate inhomogeneous meeting of being heated causes valve plate distortion, also causes valve plate stuck or leak easily.In addition, also exist a kind of artificial blind plate to cut off the mode of flue, still this mode can not onlinely be cut off, and operating environment is poor, and labor intensity is big, and the operating time is long, has finally influenced normal production and personal device security.
The model utility content
The purpose of this utility model is: at the problem that above-mentioned prior art exists, propose a kind of simple in structurely, easily manufactured, good sealing effect can be carried out the high temperature gate valve that does not have the blocking-up of leaking to the high temperature media flue.
In order to reach above purpose, high temperature gate valve of the present utility model, comprise valve body and be installed in the interior valve plate of valve body, its improvements are, described valve plate is connected with the drive unit that is installed in the valve body upper end by transmission shaft, the valve plate position is installed on described valve body is provided with adapter, and the upper end of described valve plate is provided with circular blind plate, the lower end is provided with the orifice plate of conducting, and at least one end of described blind plate is an elastic sealing structure.
It is that described elastic sealing structure is spliced relatively by two floating seal plates, evenly is furnished with one group of spring assembly on the circumferencial direction of the position that keeps to the side in the cavity that described two floating seal plates are spliced to form that the utility model further improves.
It is that the inside edge of described floating seal plate is provided with the L type chimb that matches with the groove of limit stoper that the utility model further improves again.
It is evenly to be provided with one group of chamfering on the circumferencial direction of described floating seal plate outer ledge that the utility model further improves.
The beneficial effects of the utility model are: high temperature gate valve of the present utility model is simple in structure, easy to operate, the elastic sealing structure of employing not only helps the switch of valve, has avoided valve plate stuck, can also overcome the applying gap that causes because of the valve plate distortion, avoid the leakage of high temperature media.In a word, the utility model is easily manufactured, and is with low cost, and good sealing effect is applicable to mass production.

Embodiment
Embodiment one
The high temperature gate valve of present embodiment, as depicted in figs. 1 and 2, comprise valve body 2 and the valve plate 3 that is installed in the valve body 2, the upper end of valve body 2 is provided with drive unit 1, and the lower end is provided with ash-discharge opening 11, and drive unit 1 is connected with valve plate 3 by transmission shaft, driving valve plate 3 moves up and down in valve body 2, drive unit 1 adopts electric actuator, and transmission shaft is a screw type, can realize the online cut-out of gate valve; Be provided with outside the Seal cage of valve body 2 installation valve plates 3 and take over 4, the upper end of valve plate 3 is provided with circular blind plate 5, and the lower end is provided with orifice plate 6 (see figure 3)s of conducting; Blind plate 5 at least one ends are elastic sealing structure, elastic sealing structure is spliced relatively by two circular floating seal plates 7, in the cavity that two floating seal plates 7 are spliced to form, evenly be furnished with one group of spring assembly 8 near on the circumferencial direction of cavity marginal position, spring assembly 8 comprises the spring seat that is fixed on floating seal plate 7 inboards and is enclosed within spring on the spring seat, the position, inside edge of floating seal plate 7 is provided with the L type chimb that matches with the groove of limit stoper 9, and limit stoper 9 is formed (see figure 4) by two by bolt limiting stopper together.In addition, on the circumferencial direction of floating seal plate 7 outer ledges, evenly be provided with one group of chamfering 10 (see figure 5).
When valve plate 3 moves downward under drive unit 1 effect, chamfering 10 automatic Seal cages on the floating seal plate 7 with valve plate 3 guiding valve bodies 2, and compress floating seal plate 7, make spring assembly 8 be in compressive state, the Seal cage that the reaction force of spring assembly 8 promotes floating seal plate 7 and valve body 2 fits tightly sealing, 9 pairs of two floating seal plates 7 of limit stoper carry out spacing on it repels each other direction, and blind plate 5 is connected with adapter 4 contacts, thereby causes the high temperature gate valve to be closed; When drive unit 1 drive valve plate 3 moves upward, floating seal plate 7 moves laterally under the effect of spring force and is returned to nature until spring assembly 8, orifice plate 6 is connected with adapter 4 contacts simultaneously, the high temperature gate valve is in opening state, and blind plate 5 thickness T 2 of two floating seal plates 7 formations are greater than the thickness T 1 of valve body 2 Seal cages at this moment.
High temperature gate valve of the present utility model is applicable to that medium temperature is greater than 500 ℃ flue, the normal conditions lower valve plate inequality of being heated can deform, but because the reaction force of spring assembly is by the decrement decision of floating seal plate, be the difference that the difference of each spring assembly reaction force depends on corresponding valve plate amount of deformation, cause when valve plate is out of shape, floating seal plate and Seal cage still fit tightly, and the sealing effect of valve plate and valve body is remained unchanged.In addition, in order to reduce the wearing and tearing of high temperature media, on the inner headed face of taking over, lay certain thickness refractory material to valve body.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
