Abstract
A storage tank anti-explosion exhaust device comprises a barrel body and an exhaust cap arranged at the top end of the barrel body; a conical waterproof layer is arranged at the bottom end in the barrel body; an insulation layer is arranged at the connection position between the barrel body and the exhaust cap; the diameter of the exhaust cap is larger than that of the barrel body; an insulation guide device is arranged below the protruded position of the exhaust cap. The storage tank anti-explosion exhaust device is reasonable in structural design, and smart and novel in concept, is mounted at the top ends of storage tanks for materials such as petroleum and chemical materials, and is convenient to use and easy for large-scale promotion and application, the accident that the storage tank is damaged due to the rapid overpressure in the tank caused by accidental reasons is avoided, and the safe fire retardance action is achieved. The storage tank anti-explosion exhaust device is convenient to use, and is easy for large-scale popularization and application.
Description
technical field:
The utility model belongs to oil field equipment technical field, is specifically related to a kind of storage tank anti-explosion gas outlet means.
background technology:
The pressure relief device of the material storage tanks such as existing oil, chemical industry is too simple, does not have the effect of back-fire relief, and often because superpressure in tank causes tank body, damages, and affects the normal work of material storage tank.
utility model content:
The purpose of this utility model is in order to overcome weak point of the prior art, and a kind of storage tank anti-explosion gas outlet means is provided, and can ward off and exempt from, because accidental cause causes the accident generation that in tank, sharply superpressure causes storage tank to damage, can play again the effect of safe back-fire relief.
The purpose of this utility model realizes as follows: a kind of storage tank anti-explosion gas outlet means, comprise cylindrical shell, and the exhaust cap of cylinder top, it is characterized in that: the bottom of inner barrel is provided with cone shape waterproof layer, the junction of cylindrical shell and exhaust cap is provided with insulating barrier, the diameter of exhaust cap is greater than the diameter of cylindrical shell, and the outstanding below, position of exhaust cap is provided with insulation guide piece.
Described insulation guide piece by pilot bar, pressure spring, insulation sleeve and fixedly ear form.
Described waterproof layer is made by sieve tray, is covered with regular circular aperture above.
The beneficial effects of the utility model are: reasonable in design, and the novelty that is skillfully constructed, this product is arranged on the material storage tank tops such as oil, chemical industry, can ward off the accident of exempting from because accidental cause causes in tank superpressure sharply to damage storage tank and occur; Can play again safe back-fire relief effect.Easy to use, be easy to large-scale promotion application.
accompanying drawing explanation:
Fig. 1 is planar structure schematic diagram of the present utility model.
the specific embodiment:
With reference to Fig. 1, a kind of storage tank anti-explosion gas outlet means, comprise cylindrical shell 3, and the exhaust cap 1 on cylindrical shell 3 tops, the bottom of cylindrical shell 3 inside is provided with cone shape waterproof layer 4, and cylindrical shell 3 is provided with insulating barrier 2 with the junction of exhaust cap 1, insulating barrier 2 can be avoided metal and metal friction generation spark when exhaust cap 1 falls after rise, thereby play explosion-proof, the diameter of exhaust cap 1 is greater than the diameter of cylindrical shell 3, the outstanding below, position of exhaust cap 1 is provided with insulation guide piece 6.Described insulation guide piece 6 by pilot bar, pressure spring, insulation sleeve and fixedly ear form.Described waterproof layer 4 is made by sieve tray, is covered with regular circular aperture above.
Principle of work: cylindrical shell 3 is arranged on to storage tank upper end by flange 5, when tank inner pressure during in normal operating pressure the utility model in sealing state, when tank inner pressure surpasses normal pressure, when exhaust cap 1 is upwards mentioned rapidly under the effect of pressure, pilot bar drives pressure spring upwards to mention, now pressure spring is in compressive state, at pressure spring and pilot bar and insulation sleeve is fixedly housed between ear, to ward off, exempt from exhaust cap 1 metal and metal friction when pumping and produce spark and ignite fire gases in tank, thereby lay down pressure, after pressure is drained, exhaust cap 1 under the gravity of self and pressure spring under the application force of compression rebound, by pilot bar and fixedly ear accurately get back to original position, after pressure release, exhaust cap 1 sets back.Tank implosion device of air is after continuous gas explosion, pressure can rise gradually and reach certain pressure, exhaust cap 1 is opened gas can carry the upwards sprinkling of large quantity of fluid, now by the most of liquid of waterproof layer 4, can be stopped by waterproof layer 4, avoid spray liquid to the insulating barrier 2 between exhaust cap 1 and cylindrical shell 3, like this with regard to avoided the cold exhaust cap 1 in winter in the north freeze with cylindrical shell 3 together with and make whole failure of apparatus.
