Abstract
The utility model relates to an exhaust pipe explosion-proof device of a gas engine, comprising a support, a limiting block, a connecting plate, a cover plate, a Tee pipe, a counterweight plate, a sealing ring, an elastic lug, a sleeve and a rotating shaft, wherein the upper part of the Tee pipe is provided with the support and the elastic lug, the sleeve is mounted on the support and connected with the limiting block; the sleeve is internally provided with the rotating shaft which is connected with the cover plate through the connecting plate; the counterweight plate is arranged on the cover plate; and the elastic lug presses the cover plate. The exhaust pipe explosion-proof device of the gas engine is provided with the elastic lug, can reduce the number of the counterweight plates required on the cover plate through the design of deformation control amount, can fit for explosion-proof requirement under different pipeline pressures through changing the size of the elastic lug, greatly reduces the weight of the explosion-proof device and consumptive materials of the explosion-proof device, has the characteristics of simple structure, convenient mounting and maintenance, long service life and the like, and is widely applied in explosion-proof projects of exhaust pipes of gas engines.
Description
One, technical field
The utility model relates to gas engine machine outlet pipe blasting protection facilities, particularly a kind of gas engine outlet pipe flameproof apparatus.
Two, background technique
The flameproof apparatus that uses on traditional gas engine outlet pipe, generally form by spring, cover plate, hinge etc., purpose be prevent by exhaust blow out the fuel gas buring of outlet pipe (enter produce) cause the exhaust manifold overpressure and the outlet pipe explosive accident take place, brought into play effect for the gas engine outlet pipe is explosion-proof, but the flameproof apparatus of this structure exists following shortcoming or deficiency simultaneously: 1. can not automatic opening-closing, poor reliability; 2. can not be under continuous high temperature (more than 500 ℃) environment proper functioning; 3. weight is big, and consumptive material is many; 4. poorly sealed.
Three, summary of the invention
The purpose of this utility model provides a kind of gas engine outlet pipe flameproof apparatus, adopt Weight plate and elasticity hangers to be used, the assurance cover plate can be opened pressure release fast when pipeline pressure surpasses safety value, can automatically reset the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art after the pressure release.
Gas engine outlet pipe flameproof apparatus described in the utility model comprises support, limiting stopper, connecting plate 3, cover plate, three-way pipe, Weight plate, seal ring, elasticity hangers, sleeve pipe, running shaft.Described three-way pipe top is equipped with to be supported and the elasticity hangers, and sleeve pipe is installed in the support, and running shaft is installed in the sleeve pipe, is welded with limiting stopper on the sleeve pipe, and running shaft connects by connecting plate and cover plate, and Weight plate is installed on the cover plate, and the elasticity hangers is pushed down cover plate.
Wherein, described Weight plate by bolt on the cover board.Described cover plate is fixed on the sleeve pipe and can rotates around running shaft.Described cover plate is with connecting plate welding, can rotate between the upper-end surface of three-way pipe and limiting stopper around running shaft.Described elasticity hangers one end is welded on the three-way pipe, and the other end is pushed down cover plate.In the groove on described three-way pipe top seal ring is installed.Described Weight plate is two blocks of semicircle steel plates, and pushes down seal ring after cover plate is connected by bolt.
The utility model has following advantage compared with prior art:
1, the elasticity elasticity hangers of installing on the three-way pipe can prevent the cover plate shake, can automatically reset, and also can play buffer function when cover plate resets, the exhaust heat boiler of protecting engine exhaust pipe and baffler effectively and installing on exhaust manifold.
2, the elasticity elasticity hangers of installing on the three-way pipe by the design of Deformation control amount, can reduce needed Weight plate quantity on the cover plate, by changing the size of elasticity hangers, can adapt to the requirement of explosion proof under the different pipeline pressures.
3, reduce flameproof apparatus weight greatly, reduce the flameproof apparatus consumptive material.
4, convenient, the long service life of simple in structure, installation and maintenance.
Four, description of drawings
