Embodiment

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be benchmark with the direction shown in each figure all, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.

The explosion-proof mechanism of gas engine mixed gas pipeline of the present utility model is by being provided with the flame-out pressure release module that is communicated with mixture pipe, and it is flame-out that the high temperature and high pressure gas that mixture pipe internal cause generation tempering fault is produced carries out pressure release, bursts to prevent mixture pipe.

Embodiment one:

Extremely shown in Figure 5 as Fig. 3; the concrete structure of this explosion-proof mechanism of gas engine mixed gas pipeline comprises: flame-out pressure release module 31; adapter 32 and adapter support 33; flame-out pressure release module 31 is communicated with mixture pipe 34 by taking over 32; adapter 32 is fixed on the body of motor by taking over support 33; like this; when the pressure in the mixture pipe 34 reaches the cracking pressure of flame-out pressure release module 31; flame-out pressure release module 31 is opened; release pressure is normal to the mixture pipe internal pressure; and when in the mixture pipe 34 flame being arranged; flame makes flame be eliminated by flame-out pressure release module 31, guaranteeing not occur the overpressure fault in the mixture pipe 34, and in time eliminates flame.

Flame-out pressure release module 31 is the prior art equipment of buying, and this mechanism selects QFB87-00a model explosion-proof valve for use, and cracking pressure is the 3bar. major function: valve is opened rapidly when pressure surpasses 3bar; Under the situation that is lower than Open valve pressure, keep sealing; Its flame-retardant device can stop explosion time flame to leak; Can close and keep sealing after the pressure release immediately.

Adapter 32 vertically is arranged on the bottom surface, mixture pipe 34 left side of cross setting, its upper end-hole is communicated with mixture pipe 34 driving fits by taking over pad 35, its lower end right openings is communicated with flame-out pressure release module 31 driving fits by flame-out pressure release module pad 36, and it is fixing by rectangle four jiaos of construction bolts of laying 37, at this moment, flame-out pressure release module 31 realizes and being communicated with of mixture pipe 34 by taking over 32, when the pressure in the mixture pipe 34 reaches the setting pressure of flame-out pressure release module 31, flame-out pressure release module 31 is opened pressure release, and the flame in the high temperature and high pressure gas that will pass through is eliminated.

Adapter support 33 is a triangular support structure, and the lower end of a side and mixture pipe 34 is fixed, and opposite side is fixed on the body of motor, and feasible adapter 32 lower ends are fixed by adapter support 33 and are connected with flame-out pressure release module 31, upper end connection mixture pipe 34.Take over 32 and the flame-out pressure release module 31 that connects of lower end fixing by taking over support 33, at utmost reduce the influence of active force that flame-out pressure release module opens to mixture pipe.

Embodiment two:

As shown in Figure 6 and Figure 7, present embodiment is with embodiment one the main distinction: flame-out pressure release module 31 is not to be communicated with flame-out pressure release module 31 by taking over 32, be communicated with it but directly be installed in mixture pipe 34 sides by gasket seal 38, like this, when the mixture pipe internal pressure reaches flame-out pressure release module 31 cracking pressures, flame-out pressure release module 31 is opened, directly the pressure that discharges in the mixture pipe 34 is normal to pressure, and when in the mixture pipe flame being arranged, flame is by flame-out pressure release module 31, and flame is eliminated.Guarantee not occur the overpressure fault in the mixture pipe, and in time eliminate flame.

The explosion-proof working process of mechanism of gas engine mixed gas pipeline is:

During the motor normal working: combustion gas and Air mixing gas enter mixture pipe 34, this moment, mixture pipe 34 internal pressures were normal, and flame-out pressure release module 31 is closed, and mixed gas is by each manifold of mixture pipe, enter each intake duct of cylinder cap, the motor proper functioning.

When the engine mixed gas pipe pressure was too high: combustion gas and Air mixing gas entered mixture pipe 34, this moment, the mixture pipe internal pressure was unusual, when the mixture pipe internal pressure reaches flame-out pressure release module 31 cracking pressures, flame-out pressure release module 31 is opened, and release pressure reaches normal until the mixture pipe internal pressure; And when in the mixture pipe flame being arranged, flame is by flame-out pressure release module 31, and flame is eliminated.This moment, flame-out pressure release module 31 was closed, and mixed gas enters each intake duct of cylinder cap, the motor proper functioning by each manifold of mixture pipe.

This explosion-proof mechanism of gas engine mixed gas pipeline is by being provided with the flame-out pressure release module that is communicated with mixture pipe, and it is flame-out that the high temperature and high pressure gas that mixture pipe internal cause generation tempering fault is produced carries out pressure release, bursts to prevent mixture pipe.

More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
