Abstract
The application discloses multilayer seal by-pass valve, including valve gap and disk seat, its characterized in that: the disk seat epirelief is equipped with first ring channel, two annular flanges that set up inside and outside the first ring channel surround with the disk seat and form, the protruding second ring channel that can cover first ring channel at least that is equipped with in the valve bonnet bottom, be equipped with a pair of first sealing strip in the second ring channel, two in the top of annular flange imbeds a pair of first sealing strip respectively, first ring channel bottom is equipped with the second sealing strip, second ring channel internal fixation has the sealed crown plate in the first sealing strip of embedding. This bypass valve passes through the structure cooperation, increases twice first sealing strip, and it is sealed effectual that the valve gap more can the laminating when pushing down to adopt the form of turning back between first sealing strip and the second sealing strip, form the multilayer and block, prevent that the flue gas from spilling over.
Description
Technical Field
The present application relates to the field of bypass valves, and more particularly to a multilayer seal bypass valve.
Background
In the prior art, a bypass valve used in a bag-type dust collector is in a compressed closed state in order to ensure that the discharge does not exceed the standard, and a conventional bypass valve is sealed by a sealing strip, namely a valve cover, and is pressed down to realize sealing, so that air leakage is inevitable in long-term operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a multilayer seal bypass valve to overcome not enough among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme:
the embodiment of the application discloses multilayer seal bypass valve, including valve gap and disk seat, its characterized in that: the disk seat epirelief is equipped with first ring channel, two annular flanges that set up inside and outside the first ring channel surround with the disk seat and form, the protruding second ring channel that can cover first ring channel at least that is equipped with in the valve bonnet bottom, be equipped with a pair of first sealing strip in the second ring channel, two in the top of annular flange imbeds a pair of first sealing strip respectively, first ring channel bottom is equipped with the second sealing strip, second ring channel internal fixation has the sealed crown plate in the first sealing strip of embedding.
Preferably, in the multilayer seal bypass valve described above, the two annular ribs are integrally formed with the valve seat.
Preferably, in the one of the above multilayer seal bypass valves, the seal ring plate is disposed between a pair of the first seal strips.
Preferably, in the above multilayer sealing bypass valve, the first sealing strip is a hollow sealing strip, and the second sealing strip is a solid sealing strip.
Preferably, in the above multilayer sealing bypass valve, the sealing ring plate is integrally formed with the valve cover.
Compared with the prior art, the utility model has the advantages of:
this bypass valve passes through the structure cooperation, increases twice first sealing strip, and it is sealed effectual that the valve gap more can the laminating when pushing down to adopt the form of turning back between first sealing strip and the second sealing strip, form the multilayer and block, prevent that the flue gas from spilling over.
Drawings
In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present application, and it is obvious for those skilled in the art to obtain other drawings based on the drawings without creative efforts.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the multilayer sealing bypass valve in the present embodiment includes a valve cover 1 and a valve seat 2, a first annular groove 3 is convexly disposed on the valve seat 2, the first annular groove 3 is formed by surrounding an inner annular rib 4 and an outer annular rib 4 with the valve seat 2, a second annular groove 5 that can at least cover the first annular groove 3 is convexly disposed at the bottom of the valve cover 1, a pair of first sealing strips 6 is disposed in the second annular groove 5, the top ends of the two annular ribs 4 are respectively embedded into the pair of first sealing strips 6, a second sealing strip 7 is disposed at the bottom of the first annular groove 3, and a sealing ring plate 8 embedded into the first sealing strip 7 is fixed in the second annular groove 5.
Further, the two annular ribs 4 are integrally formed with the valve seat 2.
Further, a seal ring plate 8 is provided between the pair of first seal strips 6.
Further, the first sealing strip 6 is a hollow sealing strip, and the second sealing strip 7 is a solid sealing strip.
Further, the sealing ring plate 8 is integrally formed with the valve cover 1.
In this technical scheme, this bypass valve passes through the structure cooperation, increases twice first sealing strip, and it is sealed effectual that the valve gap more can the laminating when pushing down to adopt the form of turning back between first sealing strip and the second sealing strip, form the multilayer and block, prevent that the flue gas from spilling over.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The foregoing is merely a detailed description of the present application, and it should be noted that modifications and embellishments could be made by those skilled in the art without departing from the principle of the present application, and these should also be considered as the protection scope of the present application.
