Abstract
A kind of guider from open-close type safety relief explosion proof door, the top of upper flange plate sets bonnet, leading truck is at least 3, they are vertically set on the outward flange position of upper flange plate, the cross section of leading truck is in door shape, and its openend is set and the one-to-one guide pad of leading truck respectively towards the center of bonnet, the outward flange end of bonnet, the outer end of each guide pad stretches in corresponding leading truck respectively, to realize that it being capable of vertically moving along leading truck.The utility model compared with prior art there is frictional force to reduce, and running resistance is small, the advantages that being not in bite phenomenon.
Description
Technical field the utility model is related to a kind of explosion proof door, more particularly to a kind of guider of explosion proof door.
Background technology is supplying the fields such as generating, chemical industry, oil, heat supply, to prevent inflammable medium from causing device damage and fire
Calamity, conventional safety device are to be from open-close type safety relief explosion proof door, existing explosion proof door primary structure：Flange
Upper flange plate top set bonnet, bonnet is pressed on the sealing surface of upper flange plate, and uniform vertically-guided bar is set on upper flange plate,
Guide plate corresponding with guide rod, guide rod both pass through the hole on corresponding guide plate, the bonnet respectively at the edge of bonnet
Centre bit install vertical middle guide rod, be socketed buffer spring on the middle guide rod, the top of middle guide rod through respectively with
The support that each guide rod top is fixed, magnetic suction disc is set in the middle part of support, the top of middle guide rod still passes through the magnetic suction disc, in
Between the top of guide rod set upper sucker corresponding with magnetic suction disc, sucker is fixed on the top of middle guide rod by adjusting nut on this
End.The explosion proof door of this structure is to utilize adjustable magneticaction and middle guide rod, buffering between magnetic suction disc and upper sucker
The spring-force driven dual of spring etc., the automatic open close of bonnet is realized, complete venting of dust explosion.Understand, existing explosion proof door is to utilize guide rod
Realized with the cooperation of guide plate and be oriented to and reset, the drawbacks of this guidance mode is present is：Guide plate can produce one to guide rod
Fixed running resistance, increases friction, bite easily occurs, deviates so that being oriented to position；Further, since explosion proof door is in height
Worked under warm environment, guide plate and guide rod can deform for a long time, make guide effect relatively low, so as to ensure that venting of dust explosion is suitable
Profit is carried out.
Content of the invention the purpose of this utility model is that providing one kind can make guide effect more preferable, targeting part not shadow
Ring the guider from open-close type safety relief explosion proof door of venting of dust explosion.
The utility model is mainly in the improvement of the existing targeting part from open-close type safety relief explosion proof door, particular technique
Scheme is as follows：
The utility model mainly includes upper flange plate and bonnet, and the top of upper flange plate sets bonnet, and the utility model is also
Including leading truck and guide pad, wherein leading truck is at least 3, and they are vertically set on the outward flange position of upper flange plate,
The cross section of leading truck is in door shape, and its openend is towards the center of bonnet；The outward flange end of the bonnet is set respectively
With the one-to-one guide pad of leading truck, the outer end of each guide pad stretches in corresponding leading truck respectively, with reality
Now it being capable of vertically moving along leading truck.
As a preferred scheme of the present utility model, the inwall of each leading truck is all provided with ceramic-lined.
As a preferred scheme of the present utility model, the guide pad stretches into guiding in cylinder, its axial outer end portion
In frame.
As a preferred scheme of the present utility model, the cross section of the guide pad is in T shape, and its outer end stretches to
In leading truck.
The utility model does not change existing other parts from open-close type safety relief explosion proof door, is directed to bar and leads
Substituted to plate, the top of leading truck is still to connect the support of explosion proof door, during venting of dust explosion, while bonnet opens and closes, guide pad and
Leading truck plays a part of being oriented to and resetted, and using the guider of the utility model structure, has compared with prior art such as
Lower advantage：
1st, frictional force reduces, and running resistance is small, is not in bite phenomenon, ensures to be oriented to the accuracy of position；
2nd, it will not be deformed under hot environment, ensure guide effect, ensure that venting of dust explosion is smoothed out.
3rd, it is easy to safeguard and repair, it is applied widely.
Illustrate the top cross-sectional view that Fig. 1 is the utility model embodiment 1.
Fig. 2 is the top cross-sectional view of the utility model embodiment 2.
Next embodiment just elaborates to the utility model in conjunction with the accompanying drawings and embodiments
Embodiment 1
A kind of guider from open-close type safety relief explosion proof door, as shown in figure 1, the top of upper flange plate 101 sets valve
Lid 102, the outward flange of upper flange plate are vertically arranged 3 uniform leading trucks 103, and the cross section of leading truck is in door shape, and it is opened
Mouth end is all provided with ceramic-lined 104 towards the center of bonnet, the inwall of each leading truck；The outward flange end part of the bonnet
Guide pad 105 one-to-one with leading truck is not set, and guide pad is in cylinder, and its axial outer end portion is stretched into leading truck, with reality
Now it being capable of vertically moving along leading truck.
Embodiment 2
A kind of guider from open-close type safety relief explosion proof door, as shown in Fig. 2 the top of upper flange plate 201 sets valve
Lid 202, the outward flange of upper flange plate are vertically arranged 3 uniform leading trucks 203, and the cross section of leading truck is in door shape, and it is opened
Mouth end sets guide pad 204 one-to-one with leading truck respectively towards the center of bonnet, the outward flange end of the bonnet,
The cross section of guide pad is in T shape, and its outer end is stretched in leading truck, to realize that it being capable of vertically moving along leading truck.
