Description
Technical field
The utility model relates to cigarette air valve technical field, in particular to a kind of blinds valve sealing means.
Background technique
Blinds valve is cogeneration and cement producing line key subsidiary engine equipment, and blinds valve needs to have in working condition
There is good leakproofness, generally require slip < 1%, if cannot reach, when cogeneration, waste heat will leak waste energy
Amount, generating efficiency are low.When stopping generating electricity, when overhauling boiler, since blinds valve slip is big, the waste of waste heat is caused, can be given
Production brings certain economic loss, while the high staff of pot in-furnace temperature also cannot be introduced into maintenance.So solving louver valve
Door sealing is extremely important.It is internal again since blinds valve operating temperature is high (generally 300~450 DEG C, reach as high as 600 DEG C)
Blade, axis etc. can all have thermal expansion at work, therefore the sealing for solving blinds valve is again extremely difficult.
Utility model content
In view of this, the utility model is directed to a kind of blinds valve sealing means, seal form is reliable, and convenient for safeguarding
And installation, there is preferable effect.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of blinds valve sealing means, are installed on vane plate, and the vane plate rotation is set on valve body, it is characterised in that
Include:
Diaphragm seal is removably fixedly arranged on the edge of the vane plate；
Be installed with stud in the edge of the vane plate, described diaphragm seal one end is sheathed on the stud, and by with
The fastening nut of the stud cooperation constitutes the diaphragm seal in the fixation on the vane plate.
Further, in being installed with several sharfs on the valve body, the vane plate centered on the sharf and
It rotates and is arranged relative to the valve body.
Further, band steel press strip is equipped between the fastening nut and the diaphragm seal.
Further, relative to the one end connecting with the vane plate, the other end of the diaphragm seal is configured to have
10~15 degree of angle.
Further, the diaphragm seal uses the elastic stainless steel material with high temperature resistance to be made.
Compared with the existing technology, the utility model has the advantage that
(1) diaphragm seal, is detachably secured to the edge of vane plate by blinds valve sealing means described in the utility model,
Convenient for the installation and maintenance to sealing device, while there is preferable effect.
(2) band steel press strip can make fastening nut stronger for the fixation of diaphragm seal.
(3) diaphragm seal is configured to the angle with 10~15 degree, can make sealing effect more preferably.
(4) material uses the elastic stainless steel with high temperature resistance, keeps diaphragm seal more durable, the service life is longer.
Detailed description of the invention
The attached drawing for constituting a part of the utility model is used to provide a further understanding of the present invention, this is practical new
The illustrative embodiments and their description of type are not constituteed improper limits to the present invention for explaining the utility model.?
In attached drawing:
Fig. 1 is the scheme of installation of blinds valve sealing means described in the utility model embodiment；
Fig. 2 is the schematic diagram of blinds valve sealing means closed state described in the utility model embodiment；
Fig. 3 is the schematic diagram of blinds valve sealing means open state described in the utility model embodiment；
Description of symbols:
1- valve body, 2- sharf, 3- vane plate, 4- fastening bolt, 5- stud, 6- band steel press strip, 7- diaphragm seal.
Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, 2, the present embodiment is related to a kind of blinds valve sealing means, the leaf being installed in the valve body 1 of louver valve
In sheet 3, for being sealed to louver valve, to reduce the inleakage of louver valve, boiler afterheat utilization rate is promoted, improve hair
Electricity, wherein vane plate 3 is set on valve body 1 by the rotation of sharf 2.
Specifically, being fixedly installed one or more studs 5 in the edge of the vane plate 3 of louver valve, covered on stud 5
One end of diaphragm seal 7 is fixed on stud 5 equipped with diaphragm seal 7, and with fastening nut 4.Pass through fastening nut 4 and stud 5
Be spirally connected relationship, and diaphragm seal 7 can be made to be detachably secured on vane plate 3, in this way convenient for the installation of diaphragm seal 7 and later period pair
The maintenance and replacement of diaphragm seal 7 have preferable effect.
To make the sealing effect of diaphragm seal 7 more preferably, diaphragm seal 7 is configured to the angle with 10~15 degree, such as Fig. 3 institute
Show, in this way when contacting with adjacent vane plate 3, pressing effect is more preferable, seals closer.
To keep fixation of the diaphragm seal 7 on vane plate 3 stronger, it is additionally provided between fastening nut 4 and diaphragm seal 7 flat
Steel press strip 6, band steel press strip 6 and the gasket of the prior art have the same effect, and details are not described herein.
In the present embodiment, diaphragm seal 7 can make diaphragm seal using having the elastic stainless steel material of high temperature resistance to be made
More durable, the service life is longer, saves the cost of maintenance and repair, has preferable effect.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
