Accompanying drawing explanation
Fig. 1 is the perspective view of cylinder cap described in the utility model one embodiment.
Fig. 2 is the schematic diagram of steel cylinder system described in the utility model one embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
Usually, at the opening of steel cylinder, namely the upper end of steel cylinder has open-top screw thread, is convenient to the cylinder cap that locks.Existing cylinder cap generally just plays the effect of protection steel cylinder upper bottle valve; but cylinder cap described in the utility model is provided with locking and fastening system; when there is Leakage Gas; the locking of cap body is sealed with the opening of steel cylinder; can guarantee that the gas that steel cylinder exposes can not be leaked in environment; play the effect of protection surrounding environment, therefore require better sealing and fastness.
Fig. 1 is the perspective view of cylinder cap described in the present embodiment.As shown in Figure 1, cylinder cap comprises cap body 100 and the locking and fastening system be positioned on cap body 100.Described locking and fastening system comprises cylinder cap screw thread 1, tightening nut 120 and leak-proof gasket 110.
Cap body 100 is cylindrical body, and described cylindrical body comprises end face 10 and bottom surface 20, and wherein end face 10 seals and bottom surface 20 is opened wide.When steel cylinder leaks air situation, by the bottom surface 20 of cylinder cap towards lower cover in steel cylinder outlet port, the cylinder valve on steel cylinder is contained within cap body 100.Described cylinder cap screw thread 1 is positioned at described cap body 100 inwall one end near described bottom surface 20, the bottom surface 20 of cylinder cap towards lower cover after steel cylinder outlet port, rotating cap body 100 makes cylinder cap screw thread 1 chimeric gradually with steel cylinder screw thread, is sealed within cap body 100 by the cylinder valve of steel cylinder.
In order to realize the chimeric of steel cylinder screw thread and cylinder cap screw thread 1, in correspondence with each other, if namely steel cylinder screw thread is positive tooth, then cylinder cap screw thread 1 is anti-tooth to the screw thread of steel cylinder screw thread and cylinder cap screw thread 1, otherwise if steel cylinder screw thread is anti-tooth, then cylinder cap screw thread 1 is positive tooth.
Locking and fastening system also comprises the tightening nut 120 be positioned on end face 10.Tightening nut 120 is fixed on cap body 100, when cap body 100 covers after on steel cylinder, by fastening tightening nut 120 with spanner and rotating cap body 100, can be fixed on steel cylinder by cap body 120 more closely.
In order to increase sealing further, bottom surface 20 is provided with leak-proof gasket 110.Because bottom surface 20 is unlimited, therefore the ring-type of tightening nut 120 also for opening wide, is fixed on bottom surface 20.The bottom surface 20 of cap body 100 is towards lower cover after steel cylinder outlet port, and first leak-proof gasket 110 will touch the surface of steel cylinder, and along with the rotation of cap body 100, leak-proof gasket 110 can be gradually compressed, and then is shut completely in the gap between steel cylinder and cylinder cap.
Concrete, leak-proof gasket 110 should take durable and that quality is softer material, be Teflon in the present embodiment, but the utility model is not as limit.
In the present embodiment, cylinder cap further comprises the outlet pipe 130 being communicated to cap body 100 inside, its object is to, after steel cylinder is covered cylinder cap and transports scene, the gas leaked in cap body 100 be discharged to process by outlet pipe 130 when post-processed.Concrete, the material of outlet pipe 130 is stainless steel, and its one end is fixed on the side of cap body 100 and is communicated to the inner space of cap body 100, and the other end has interface 133, interface 133 makes outlet pipe 130 can receive on outside exhaust treatment system, to perform the maintenance of steel cylinder.
Outlet pipe 130 has valve 131, and it is in normally closed state, cylinder cap is fixed on after on steel cylinder, can plays the effect of sealing.When steel cylinder is transported scene, and after interface 133 receives exhaust treatment system, Open valve 131 is to get rid of the gas in cap body 100.
Outlet pipe 130 also has pressure gauge 132, for detecting the pressure in cap body 100.The initial value of pressure gauge 132 is zero.When steel cylinder leaks air, be fixed to by cylinder cap on steel cylinder, along with gas drains to cap body 100 inside gradually, the pressure of cap body 100 inside can increase gradually, and the value that specifically can show as pressure gauge 132 is increasing.Operator can judge the pressure in cap body 100 according to the value to pressure gauge 132 read, thus its internal gas of process that takes appropriate measures.
As shown in Figure 2, the utility model additionally provides steel cylinder system, comprises steel cylinder 200 and above-mentioned cylinder cap.The opening of steel cylinder 200 has cylinder valve, and described cylinder valve is positioned at the top of steel cylinder 200.Cylinder cap can be fixed on the opening of steel cylinder 200, is sealed in cap body 100 by described cylinder valve.
Introduce the using method of cylinder cap described in the present embodiment below in detail.
Placing the scene of steel cylinder, usually have the sensor of gas leakage, when there being steel cylinder to occur Leakage Gas, sensor can detect the concrete steel cylinder occurring leaking, and gives the alarm.Staff can learn the appearance of Leakage Gas situation according to alarm and find the concrete steel cylinder occurring leaking.
Now, staff brings Gas feeding respiratory protection tool (SCBA) to enter scene, described cylinder cap is placed on the top of corresponding steel cylinder, and turns tightening nut 120 by instrument, by the inside of the cylinder valve of steel cylinder sealing with cap body 100.
Afterwards, gas cylinder is transported scene by staff, and observe the value of pressure gauge 132, and interface 133 is received exhaust treatment system, opening valve 131 can be discharged to the gas leaked in cap body 100 in exhaust treatment system.
The cylinder cap that the utility model provides has cap body and locking and fastening system, and locking and fastening system includes cylinder cap screw thread, tightening nut and leak-proof gasket, guarantees that the gas that steel cylinder exposes can not be leaked in environment.Cylinder cap also comprises the outlet pipe being communicated to cap body inside, and outlet pipe can connect exhaust treatment system process to be leaked to the gas in cap body.The steel cylinder system that cylinder cap and steel cylinder form, to be locked in the gas that steel cylinder spills in cylinder cap thus to avoid the appearance of serious consequence.
Obviously, those skilled in the art can carry out various change and modification to model utility and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
