On above-mentioned cross top a ladder can be arranged, make the cross end diameter less than its root and be slightly less than the bayonet end internal diameter of above-mentioned insertion pipe, the endoporus of insertion pipe is inserted in the cross upper end in the time of in insertion pipe inserts snap close piece, makes spool more stable in coal gas stream.
The material of above-mentioned seal ring can be rubber.Above-mentioned link can be connected by internal and external threads with snap close piece.
Link with the gas-tank outlet pipe connection during use is screwed on the outlet valve of gas-tank, insertion pipe one end is connected with reduction valve, depress the outer sleeve of snap close piece, the bayonet end of insertion pipe is inserted in the spliced eye of snap close piece, ball on the snap close piece is stuck in the ball draw-in groove on the insertion pipe, move on the outer sleeve ball is pinned, insertion pipe promptly is connected on the snap close piece.The insertion end of insertion pipe moves down spool to the cross that presses down spool, and the seal ring on the spool disk separates with seal ring in the snap close piece endoporus, and coal gas just can enter the endoporus of insertion pipe through the space between disk perimeter and cross and discharge.The spool cross inserts and is difficult for swing in the insertion pipe.
Push down the outer sleeve of snap close piece downwards, just can extract insertion pipe, the insertion end of insertion pipe is no longer oppressed the cross of spool at this moment, spool moves up under the effect of spring, seal ring in seal ring on the spool and the snap close piece endoporus is pressed together, seal up the endoporus of snap close piece, coal gas can not leaked.
In sum, this gas-tank outlet pipe connection connects and convenient disassembly, and is difficult for gas leakage, and safe, the life-span is long.
Description of drawings
Fig. 1 is a gas-tank outlet pipe connection structural drawing of the present utility model;
Fig. 2 is the plan view of the disk spool of gas-tank outlet pipe connection shown in Figure 1;
Fig. 3 is the structural drawing of the insertion pipe of gas-tank outlet pipe connection when inserting snap close piece.
Embodiment
Below in conjunction with accompanying drawing gas-tank outlet pipe connection of the present utility model is described further.
As shown in Figure 1, gas-tank outlet pipe connection of the present utility model comprises link 1, the snap close piece 2 that links together by screw thread and link 1, is inserted in the insertion pipe 3 on the snap close piece.Link has an endoporus 4, and there is outside thread the lower end, and the upper end has outside thread to be used for being connected with snap close piece 2.
Snap close piece 2 is made up of the outer sleeve 6 and the inner sleeve 5 that are sleeved on together, in the middle of inner sleeve 5 and outer sleeve 6 annular space is arranged, and a spring 7 is equipped with in the inside, and outer sleeve 6 can be slided up and down outside inner sleeve 5.The inner sleeve upper end has the spliced eye 8 of taper to be used for being connected with insertion pipe 3, and the lower end is tapped tapped hole, is used for being connected with link 1.On the top of inner sleeve 5 sidewalls 6 circular holes are arranged, there is ball 9 the circular hole the inside.
A spool 17 is arranged at endoporus 4 tops at link.Be connected with a spring 18 below the spool 17, the spring lower end is installed in the endoporus of link; In conjunction with Fig. 2 as can be seen, a criss-cross support 14 is arranged above the spool, a rubber seal 16 is arranged on the spool 17, the bracket end diameter is less than root diameter (RD).One rubber seal 15 is arranged at the endoporus bottom below snap close piece inner sleeve 5.Spring 18 pressed spools 17 seal up by the endoporus 8 of seal ring 15,16 with snap close piece, can prevent gas leakage.
There is the outside thread 12 that links to each other with reduction valve the upper end of insertion pipe 3, and insertion end 10 shapes of bottom and spliced eye 8 inwalls of snap close piece inner sleeve 5 match, and a circle ball draw-in groove 13 is arranged on insertion end 10.
As shown in Figure 3, when the insertion end 10 of insertion pipe 3 was inserted the spliced eye 8 that overlaps in the snap close piece, the annular ball draw-in groove of insertion pipe 3 was just in time blocked by the ball on the snap close piece inner sleeve 9, and outer sleeve 6 inwardly chokes ball 9, and insertion pipe 3 can not upwards be extracted.The insertion end 10 of insertion pipe 3 contacts with the spliced eye inwall of the inner sleeve 5 of snap close piece coincide.The entry end of the insertion end 10 of insertion pipe 3 withstands the cross 14 above the spool, corrects on the cross 14 in the endoporus that inserts insertion pipe 3, and when swiftly flowing coal gas stream flow through spool 17, spool 17 can not swung.Under the effect of insertion pipe 3, spool 17 moves down certain distance, and the seal ring 15 in seal ring 16 and the snap close piece inner sleeve on the spool is separated, and coal gas can enter the endoporus of insertion pipe by the space between cross.
Gas-tank outlet pipe connection of the present utility model is owing to adopt the plug lock connection mode, and easy to use, the disk spool of middle band cross makes that this joint sealing is tighter, leakiness coal gas not, and Security is good.
