Abstract
The invention discloses a gas return port degassing fixture. The gas return port degassing fixture is characterized in that a circular hole is drilled in the middle of a stainless steel plate, the two ends of the stainless steel plate are respectively connected to hanging plates so as to form a U-shaped structure, the other ends of the two hanging plates are respectively provided with hollow L-shaped hanging holes, a conical hole is drilled in the tail end of a T-shaped double-screw bolt, and a nut is welded in the middle of the stainless steel plate and corresponds to the circular hole so as to ensure that after the T-shaped double-screw bolt is screwed into the nut, the center of the T-shaped double-screw bolt is mutually and tightly matched with an ejector pin of a gas return port. Through the arrangement, the gas return port degassing fixture is simple in structure and convenient to operate, the hanging plates are tightly matched with hanging lugs at the two sides of the gas return port, the stability and accuracy of the degassing fixture are ensured, and the gas return port degassing fixture is relatively safe and reliable.
Description
Technical field
The present invention relates to a kind of frock of gas returning port venting during for vehicle liquefied natural gas bottle topping up.
Background technique
Existing Vehicular liquefied natural gas cylinder, when topping up, need first check that gas cylinder has or not anomaly, determine without starting topping up after the potential safety hazards such as leakage, cannot fill smoothly but its inner bag gas pressure is too high during usually because of topping up, general way is to open gas returning port to exit, cylinder liner gas pressure is reduced, thereby make LNG Liquefied natural gas be charged into smoothly inner bag, and gas cylinder overhauls or while in case of emergency needing to exit, need to open atmospheric valve exits, unload the connecting tube that connects atmospheric valve, opening atmospheric valve can exit, while use after assembling like this, for ensureing the tightness of pipe-line system, need again carry out air tightness test, so not only increase cost, and expend the time.
Summary of the invention
Object of the present invention is that a kind of gas returning port venting frock addressing the above problem is provided.
To achieve these goals, the present invention is drilled with circular hole in the centre of corrosion resistant plate, two ends connect respectively link plate and form U-shaped structure, the L-type hanging hole of hollow out is set respectively at the other end of two link plates, T-shaped double-screw bolt end is drilled with cone shape hole, it is middle and corresponding with circular hole that nut is welded on corrosion resistant plate, to guarantee that T-shaped double-screw bolt makes the center of T-shaped double-screw bolt and the thimble of gas returning port cooperatively interact closely after being screwed in nut.
By above setting, the present invention is not only simple in structure, easy to operate, and link plate coordinates closely with the hanging nose of gas returning port both sides, has guaranteed steadiness and the accuracy of venting frock, safety and reliability.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of link plate.
In figure: 1, corrosion resistant plate, 2, link plate, 3, L-type hanging hole, 4, T-shaped double-screw bolt, 5, nut.
Embodiment
As shown in Figure 1, 2, the present invention is drilled with circular hole in the centre of corrosion resistant plate 1, two ends connect respectively link plate 2 and form U-shaped structure, the L-type hanging hole 3 of hollow out is set respectively at the other end of two link plates 2, T-shaped double-screw bolt 4 ends are drilled with cone shape hole, it is middle and corresponding with circular hole that nut 5 is welded on corrosion resistant plate 1, to guarantee that T-shaped double-screw bolt 4 makes the center of T-shaped double-screw bolt 4 and the thimble of gas returning port cooperatively interact closely after being screwed in nut 5.By above setting, when venting, L-type hanging hole 3 of the present invention is stuck on the hanging nose of gas returning port both sides and is fixed, when the cone shape hole of T-shaped double-screw bolt 4 ends is aimed at the thimble of gas returning port, start to tighten inwards T-shaped double-screw bolt 4, until the jacking of gas returning port thimble is gone, carry out bleed air operation.
Claims (1)
1. a gas returning port venting frock, it is characterized in that: the centre at corrosion resistant plate is drilled with circular hole, two ends connect respectively link plate and form U-shaped structure, the L-type hanging hole of hollow out is set respectively at the other end of two link plates, T-shaped double-screw bolt end is drilled with cone shape hole, it is middle and corresponding with circular hole that nut is welded on corrosion resistant plate, to guarantee that T-shaped double-screw bolt makes the center of T-shaped double-screw bolt and the thimble of gas returning port cooperatively interact closely after being screwed in nut.
