Heat such that it is able to pressure-reducing chamber is preheated, prevents pressure-reducing chamber frosting fault.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention gas-fueled vehicles natural gas pressure-reducing valve.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, be the structural representation of embodiment of the present invention gas-fueled vehicles natural gas pressure-reducing valve.The present embodiment
Gas-fueled vehicles natural gas pressure-reducing valve include metal shell 1, be arranged on the insulation inner shell 2 inside metal shell 1 and peace
It is contained in the ceramic heater 3 in insulation inner shell 2 and pressure-reducing chamber 4, insulation inner shell 2 is provided with phase internal with insulation inner shell 2 respectively
Logical preheating water entrance 21 and preheating water outlet 22, insulation inner shell 2 is additionally provided with the pressurized gas inlet communicated with pressure-reducing chamber 4
23 and gases at high pressure outlet 24, pressurized gas inlet 23 is provided with high pressure admission assembly, and pressurized gas inlet 23 is near pressure-reducing chamber 4
Inwall on be provided with mounting groove, high pressure admission assembly include movable slider 51, spring 52, prism set 53, spheroplast 54, seal
Plug 55, adapter sleeve 56 and inlet suction port 57, adapter sleeve 56 be positioned at pressurized gas inlet and with insulation inner shell 3 company of being screwed
Connecing, inlet suction port 57 is screwed with the outer end of adapter sleeve 56 and is connected, and the logical of the inside and outside two ends of connection is offered in the inside of adapter sleeve 56
The inner of hole and adapter sleeve 56 has dug chute, and prism set 53 is installed in chute slidably, and the two ends of prism set 53 are respectively
Being provided with slot, spheroplast 54 is installed in the slot that prism overlaps 53 the inners, and seal plug 55 is installed in prism and overlaps inserting of 53 outer ends
In groove, movable slider 51 is installed in mounting groove, and movable slider 51 connects installation away from the side of spheroplast 54 by spring 52
