Abstract
An impact-resistant integrated end plug is used for a long-tube trailer gas cylinder for transporting industrial gas or natural gas. A pressure releasing device and, an escape pipe passage, a blowdown pipe passage and a gas inlet and outlet control valve passage are processed on the end plug, so that a blowdown pipe, an escape pipe, a gas inlet and outlet control valve and a pressure releasing device can be connected or mounted onto the end plug intensively, and the structure is simplified. Holes are arranged on the lateral sides of the passages so that the blowdown pipe, the gas inlet and outlet control valve and the pressure releasing device can be connected along the direction perpendicular to the axis of the end plug, the length of a control box is reduced, the length of a container capable of being utilized is increased, and the end plug has the protecting functions for the pipelines and the devices and prevents leakage when an operation box is impacted in accidents. Further, the passages which are independent to each other reduce or eliminate affection of impact waves onto the pressure releasing device, thereby avoiding mistaken explosion of the pressure releasing device.
Description
Technical field
The utility model relates to a kind of shock resistance formula long-tube trailer gas cylinder collection dress end plug, in order to control valve, blowoff line, the blowdown piping of the control gaseous turnover gas cylinder that is integrated and connected, and as the carrier of setting pressure bleeder.
Background technique
In modern industry and the life, various industrial gas, as hydrogen, helium, helium etc., and the use of combustion gas is more and more, because the narrow limitation of pressure piping means of transportation has quite a few industrial gas and combustion gas to adopt long-tube trailer to transport.
The end plug of long-tube trailer use at present, have blowdown and two passages of turnover gas, channel aperture is on the end plug front-end face, the direction of edge and end plug parallel axes is connected blowoff line, turnover gas control valve, and while installation threeway before control valve is drawn branch road and come setting pressure bleeder and blowdown piping.This structure, at first make the connecting pipeline complexity, component are more, secondly these pipelines and device are all stretched in the end plug front-end face outside, make long-tube trailer by blowoff line, the turnover gas control valve, the operating box length that pressure-relieving device and blowdown piping etc. are formed increases, reduce the length that frame type container can effectively utilize, once more since pipeline and device stretch out in the end face outside, as have an accident and make its operating box to being impacted, cause the interior various pipelines of operating box and the damage of device easily, lead to the leakage of loading gas, at last, because pressure-relieving device and turnover gas control valve are connected in same passage, the high speed during turnover gas, the shock wave that high pressure draught produces influences pressure-relieving device upstream side pressure, make its mistake explosion, cause unnecessary gas waste.
Summary of the invention
In order to overcome existing end plug existing problems, the utility model provides a kind of new collection dress end plug, by this end plug, can simplify the connecting pipeline parts, shortens operating box length, improve impact resistance, and this end plug is simple in structure, is easy to manufacturing.
The technological scheme that its technical problem that solves the utility model adopts is:
Shock resistance formula collection dress end plug is processed with the autonomous channel on the end plug, be respectively applied for the setting pressure bleeder and connect blowdown piping, connects the turnover gas control valve, connect blowoff line, and each channel aperture is on the end plug side.
Further, pressure-relieving device by individual passage and the bottle in a gas communication, but and on passage, process the setting pressure bleeder the seat.
Further, each channel aperture is on the side, and according to the end plug use position, each channel selecting is in suitably side perforate.
Further and the connecting thread of blowdown piping, blowoff line, turnover gas control valve can adopt cylindrical thread, also can adopt tapered tread.
This end plug comprises and is used for setting pressure bleeder and the passage that is connected blow-down pipe (6), is used to connect the passage (7) of drain pipe, and is used to be connected the passage (9) that passes in and out gas control valve.It is characterized in that: at first various pipelines and device are concentrated and to be connected or to be installed on the end plug; simplified structure; reduce part; secondly various channel aperture are on the side; make pressure-relieving device; drain pipe; component such as control valve are along connecting perpendicular to the end plug axial direction; shorten operating box length; once more; as have an accident operating box produce impacted since the end plug front-end face stretch be in outside, play the effect of protection pipeline and device; at last; adopt individual passage to connect turnover gas control valve and pressure-relieving device respectively, weaken or eliminated the influence of shock wave, avoid its mistake explosion pressure-relieving device upstream side pressure.

Fig. 2 is the A-A view of Fig. 1.
Among the figure 1. with the gas cylinder connecting thread, 2. seal groove, 3. end plug side, 4. blowdown piping connecting thread, 5. pressure-relieving device fitting seat, 6. pressure-relieving device and emptying passage, 7. drain outlet, 8. blowoff line connecting thread, 9. turnover gas passage, 10. pass in and out gas control valve connecting thread, 11. end plug front-end faces
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
End plug screw thread (1) is used for being connected with gas cylinder, seal groove (2) is used to install seal ring, guarantee the sealing between gas cylinder and end plug, each channel aperture is on end plug side (3), be used to connect each pipeline and device, the force surface that while installs as end plug, pressure-relieving device fitting seat (5) is used to install rupture disk, make the gentle pressure of the inside of a bottle of pressure-relieving device upstream side pressure communicate by passage (6), blowdown piping connecting thread (5) can be processed into cylindrical thread or tapered thread, be used to connect blowdown piping, pressure-relieving device downstream side pressure and atmosphere are communicated, blowoff line connecting thread (7) can be processed into cylindrical thread or tapered thread, is used to connect blowoff line, communicates by drain outlet (8) and gas cylinder inside, turnover gas control valve connecting thread (10) also can be processed into cylindrical thread or tapered thread, be used to connect control valve, communicate, thereby the realization gas cylinder is inflated gas cylinder outside air feed or external air source by passage (9) and gas cylinder.
Claims (4)
1. shock resistance formula collection dress end plug is characterized in that: be processed with the autonomous channel on the end plug, be respectively applied for the setting pressure bleeder and connect blowdown piping, connect the turnover gas control valve, connect blowoff line, and each channel aperture is on the end plug side.
2. shock resistance formula collection according to claim 1 dress end plug is characterized in that: pressure-relieving device is by a gas communication in individual passage and the bottle, but and processes the seat of setting pressure bleeder on passage.
