Background technique
In the prior art, general mixer case can only coordinate with nozzle, plays gas mixed function, and can not be at peripheral sensor installation or other annexes.And natural gas engine requires mixer position setting pressure sensor on air inlet pipeline.Use general mixer case, can only be in engine charge pipeline Shang Lingjia mechanism for sensor installation, the layout of engine charge pipeline is more complicated, and cost is also higher; Meanwhile, general mixer case, when assembling, is fixed nozzle, in long-term work vibration processes, easily loosening, thereby affects the mixing ability of mixer.This is the existing deficiency of prior art.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of technological scheme of used for natural gas engine mixer case, in this scheme, on mixer case, with sensor installation seat, peripheral mechanism need not be additionally added, the layout of engine charge pipeline can be greatly simplified, optimize engine structure, reduce costs; And nozzle is fixed by screws on housing, solved the loosening problem of nozzle in working procedure.
This programme is achieved by the following technical measures: it comprises end cap and base, end cap is fixedly connected with base, base is provided with air intlet and mixed gas outlet, it is characterized in that: described end cap is provided with nozzle mounting hole and end cap mounting hole, end cap inside is provided with natural gas transport passage, described natural gas transport passage is communicated with base intracavity, at base and end cap connection part, base be provided with mixer in the hole that matches of nozzle arrangements, the inwall of base is provided with nozzle fixed groove, the outer wall of base is provided with sensor installation seat, described sensor installation seat is positioned at the top of nozzle fixed groove, nozzle one end in mixer is fixed on end cap by Cock screw, the other end of nozzle is fixed in nozzle fixed groove, solved the loosening problem of mixer nozzle in service.
Described sensor installation seat is provided with installation of sensors hole and sensor probe mounting hole, sensor is fixed on sensor installation seat, the probe of sensor stretches into internal mixer by sensor probe mounting hole through base wall, directly record the pressure of internal mixer, extra additional mechanism providing additional operation, has reduced the cost of mixer.
Described air intlet is positioned at base bottom, and described mixed gas outlet is positioned at base top, and the internal diameter of base is reduced gradually by air intlet to mixed gas outlet, and such design can change airspeed, is conducive to the mixing of gas.
The center line of described nozzle fixed groove overlaps with the center line of natural gas transport channel outlet.
On described end cap, be also provided with seal groove, described end cap mounting hole site is in the periphery of seal groove.
In described seal groove, seal ring is installed, has strengthened the sealing of mixer.
Described base is fixedly connected with by Cock screw with end cap.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due on mixer case in this scheme with sensor installation seat, need not additionally add peripheral mechanism, can greatly simplify the layout of engine charge pipeline, optimize engine structure, reduce costs; Nozzle is screwed on housing simultaneously, has thoroughly solved the loosening problem of nozzle in mixer working procedure.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
