Abstract
The utility model relates to an explosion-proof device of a low temperature heat insulation liquid storage tank. A tapered plug is embedded into two O-shaped rubber sealing rings to be assembled with a taper sleeve, and the taper sleeve is fixedly connected to a tank body through a steel pipe after being solidified with the steel pipe. Due to self structural characteristics of tapered surface fit, parts are not easy to fall off after assembly, tapered surfaces adopt the two O-shaped rubber rings for sealing, so that reliability and stability of sealing are greatly improved, and possibility of leakage is thoroughly avoided. The explosion-proof device is convenient to process and assemble and favorable for organizing production, and can effectively reduce cost for manufactures.
Description
Technical field
The utility model relates to a kind of Cryo Heat Insulation wet tank flameproof apparatus, belongs to the deep cooling chemical technology field.
Background technique
The enterprise of domestic existing production Cryo Heat Insulation wet tank, the flameproof apparatus on its storage tank generally adopts the mode of using the seal with elastometic washer of single O shape between thick walled steel tube and flat cover.Because flameproof apparatus is to carry out work by vacuumizing the formation pretightening force, must vacuumize earlier just and can assemble, otherwise very easily come off between each part, brings inconvenience to production.Single O shape seal with elastometic washer requires each part processing precision high, causes cost of production to increase, and is prone to the situation that poorly sealed generation liquid is revealed.
Summary of the invention
The objective of the invention is the deficiency to above-mentioned existence, provide a kind of and be convenient to processing and assembling, and thoroughly stop the device revealed.
Realize that technological scheme of the present invention is to assemble with tapered sleeve after tapered plug embeds twice O shape rubber seal, the fixed back of tapered sleeve and steel pipe is fixed on the tank body through steel pipe.
The beneficial effect of the utility model is that the cone match of tapered plug and tapered sleeve is because the self structure characteristics make part assembling back be difficult for coming off; Use two O shape seals with elastometic washer between the conical surface; Improve the reliability and stability of sealing greatly, thoroughly stop the possibility of revealing.This device is convenient to processing and assembling, helps tissue production, and can effectively reduce the cost of manufacturer.
Description of drawings
Accompanying drawing is the sectional view of the utility model.
Embodiment
