Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises that it is on 3 that the first fittings body 1 and the second fittings body 2, the first fittings bodies 1 and the second fittings body 2 are separately positioned on a railway wagon brake pipe.
As shown in Figure 1 and Figure 2, one end of the first fittings body 1 is provided with a circle sealed groove 11, this end is contact jaw, the other end of the first fittings body 1 is provided with a circle draw-in groove, this end is joint end 12, the access section that the periphery of the first fittings body 1 is provided with the joint end 12 of the first flange body 4, the first fittings bodies 1 and the first flange body 4 is provided with first and adjusts pad 5, the first to adjust between pads 5 and the first fittings body 1 be Spielpassung.
Such as Fig. 1, shown in Figure 3, one of the second fittings body 2 is held level with both hands together, this end is contact jaw 21, the other end of the second fittings body 2 is provided with a circle draw-in groove, this end is joint end 22, the periphery of the second fittings body 2 is provided with the joint end 22 of the second flange body 6, the second fittings bodies 2 and the access section of the second flange body 6 is provided with the second adjustment pad 7; Be Spielpassung between the second adjustment pad 7 and the second fittings body 2.
As shown in Figure 1, be provided with seal ring 8 in the sealed groove 11 of the first fittings body 1.The contact jaw of the first fittings body 1 contacts with the contact jaw of the second fittings body 2, the end contact of the first flange body 4 and the second flange body 6, and by two bolts 9 the first flange body 4 and the second flange body 6 are connected, so with the first fittings body 1 be connected fittings body 2 and connect.
As shown in Figure 4, the first adjustment pad 5 of the present utility model and second is adjusted pad 7 and is the thin slice of ring, and is provided with opening on it, and opening size is 5mm, easy-to-operat personnel assembling.
In above-described embodiment, because it is 0.1～0.4mm that assembling front connector body should be given prominence to the value of flange body end face, after the assembling, size after seal ring 8 compressions should be between 4.9～5.0mm, therefore, in order to improve the airtight quality of existing Flange Joints in Braking Pipeline System for Railway Freight Cars, the utility model is adjusted pad 5 and second by first and is adjusted the critical size that pad 7 adjustment seal, and guarantees that sealing ability of bolted joint is good.Because the specification of flange body and fittings body is different, the fit dimension scope is different, and therefore, the first thickness of adjusting pad 5 and the second adjustment pad 7 can be 0.3mm, 0.5mm and 0.8mm, and each adjusts the size of pad and the size coupling of various fittings body.It is that the different carbon steel of Q235-A thickness is made that the first adjustment pad 5 and the second adjustment pad 7 all adopt material.
