Description

A kind of flame proof valve for dust transfer pipeline
Technical field
The utility model relates to safety equipment fields, and in particular to a kind of flame proof valve for dust transfer pipeline.
Background technique
With the country be related to dust conveying industrial enterprise's safe production awareness continuous enhancing, dust transfer pipeline with every The demand of quick-fried valve is also constantly expanding, and selecting up-to-standard product is put in each first paid attention in face of safety in production enterprise Demand.Do not install under normal conditions similar products result be likely to because dust explosion occurs in certain equipment in pipeline after, fire Flame propagates to a nearest equipment, explodes again, until explosion accident occurs in whole producing line, so increasing dust delivery pipe Road is very necessary with flame proof valve.
Dust transfer pipeline flame proof valve must be taken into account and normally produce circulation area, flame barrier property, seal and can Maintainability, four is indispensable, but current flame proof valve is difficult to meet aforementioned four requirement simultaneously or structure is more multiple Miscellaneous, flame proof response speed is slower.
Utility model content
The purpose of this utility model is exactly to provide that a kind of response is fast, knot to overcome the problems of the above-mentioned prior art Structure is simply to the flame proof valve of dust transfer pipeline.
The purpose of this utility model can be achieved through the following technical solutions: a kind of flame proof for dust transfer pipeline Valve, the flame proof valve include hollow flame isolation storehouse, are fixed on the export pipeline of flame isolation storehouse rear end and are plugged in flame Completely cut off the inlet ductwork of storehouse front end, rotation is equipped with the isolation flap for completely cutting off inlet ductwork in flame isolation storehouse, described The middle part for completely cutting off flap is fixed on flame by shaft rotation and completely cuts off in storehouse, and the both ends of the shaft are completely cut off by bearing and flame The inner wall in storehouse connects, and is positioned proximate to switch in junction, and the flame proof valve is equipped with for controlling the control close to switch opening and closing Device processed.Due in normal use, isolation flap be it is in the open state, i.e. isolation flap is not contacted with inlet ductwork, this When close to switch drive shaft rotation, will isolation flap turned upwards, when rotational angle reaches requirement, close to switch stop turn It is dynamic, and remain stationary, so that isolation flap is static and is kept open, at this point, opening angle, which calculates area, is not less than pipeline Sectional area;When dust explosion occurs for upstream device, controller control stops working close to switch, i.e., no longer supports barrier valve Valve, isolation flap rotates down under the effect of gravity, so that block input port pipeline, flame are blocked.The control of the utility model Device can concentrate on the control centre of factory, control flame proof valve all in factory, when control centre monitor it is a certain Place's equipment is exploded, then can simultaneously close off the flame proof valve of all upstream equipments, flame and high temperature and high pressure gas are isolated, no longer Upstream passing, to achieve the purpose that protect upstream equipment and personnel.
The front end of the inlet ductwork and the rear end of export pipeline are equipped with flange, and it is defeated by the flange to be fixed on dust It send in pipeline.
The rear end of the inlet ductwork is chamfer, and notch is in plane.
The side of isolation flap towards the inlet ductwork is fixed with gasket seal, the shape of the gasket seal and Size and the notch of inlet ductwork rear end match.It is arranged by gasket seal and the notch of inlet ductwork rear end, it is ensured that The sealing performance of flame proof valve when closed.
The bottom of the flame proof valve is equipped with cleaning door to be opened/closed.
The side wall in the flame isolation storehouse is equipped with the observation window for observing dust stratification situation.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) close to switch setting, can remote observation and control isolation flap working condition, flame proof valve response speed Rate improves safety;
(2) tight fit for passing through gasket seal and inlet ductwork, ensure that the sealing performance of device, does not have any fire Flower is scurried out;
(3) isolation flap is connected in shaft, and shaft is fixed on shell by bearing, guarantees the rotation flexibility of flap.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model;
Fig. 2 is that the survey of the utility model regards structural schematic diagram.
Wherein, 1 is inlet ductwork, and 2 be gasket seal, and 3 be isolation flap, and 4 completely cut off storehouse for flame, and 5 be export pipeline, 6 To approach switch, 7 be cleaning door, and 8 be observation window, and 9 be shaft.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited In following embodiments.
Embodiment 1
A kind of flame proof valve for dust transfer pipeline, structure is as shown in Figure 1 and Figure 2, completely cuts off storehouse including hollow flame 4, be fixed on flame isolation 4 rear end of storehouse export pipeline 5 and be plugged in flame isolation 4 front end of storehouse inlet ductwork 1, flame every Rotation is equipped with the isolation flap 3 for completely cutting off inlet ductwork 1 in exhausted storehouse 4, and the middle part of isolation flap 3 is fixed by the rotation of shaft 9 In flame isolation storehouse 4, the both ends of shaft 9 are connect by bearing with the inner wall that flame completely cuts off storehouse 4, and are positioned proximate in junction Switch 6, flame proof valve are equipped with for controlling the controller being opened and closed close to switch 6.
Wherein, the front end of inlet ductwork 1 and the rear end of export pipeline 5 are equipped with flange, and are fixed on powder by the flange In dirt transfer pipeline.The rear end of inlet ductwork 1 is chamfer, and notch is in plane.It is solid towards the side of inlet ductwork 1 to completely cut off flap 3 Surely it is equipped with gasket seal 2, the form and dimension of gasket seal 2 and the notch of 1 rear end of inlet ductwork match.Pass through gasket seal 2 are arranged with the notch of 1 rear end of inlet ductwork, it is ensured that the sealing performance of flame proof valve when closed.
The bottom of flame proof valve is equipped with cleaning door 7 to be opened/closed.The side wall that flame completely cuts off storehouse 4 is equipped with for observing dust stratification situation Observation window 8.
In the present embodiment, which is installed in dust transfer pipeline, is series between individual device, mounting distance is pressed As requested does not influence between equipment dusty gas and circulates, and isolation flap is in the open state when normal work, and opening angle is calculated Area is inspected periodically not less than pipe section product, clears up internal dust stratification.When rear end dust processing equipment due to misoperation or its When his reason causes dust explosion, controller control stops working close to switch, so that isolation flap is downward under the effect of gravity Rotation is closed inlet ductwork, and flame and high temperature and high pressure gas are isolated in this, do not transmit further along, to reach protection upstream Equipment and the purpose of personnel.
