Description
Technical field
The utility model relates to a kind of safety interlocking, particularly relates to the mesohigh large-diameter pressure vessel, as the safety interlocking of dry welded high pressure test compartment.
Background technique
At present, mainly can be divided into three kinds of shroud tub type, high pressure type and gerotor types to the repair by welding of submarine pipeline dry type, wherein high pressure dry welding high undersea hydrostatic pressures dry type welding maintenance technique was taken the lead in 1954 proposing by the U.S., began to be used for to produce the successful repair by welding charge book of the existing following deepwater field of 300m in 1966 in marine site, the North Sea.Except life support under water, outside the corollary systems such as the water surface and underwater communication contact, the key problem of underwater dry-type high pressure welding maintenance technique at first is underwater dry-type high pressure welding procedure, because pressure of ambient gas, the environmental gas composition, the variation of factors such as repair by welding subject material characteristic, the capital makes the welding arc characteristic, metallurgy characteristic and welding procedure characteristic are subjected to influence in various degree, thereby before welding repairing work under water, all need welding parameter is studied at every turn, just need set up corresponding high pressure dry STUDY ON THE WELDING testing apparatus, the main body of testing apparatus is exactly the high pressure welding experimental cabin for this reason.
Dry-type high-voltage STUDY ON THE WELDING testing apparatus must can satisfy following requirement: (1) can simulated pressure corresponds to the gaseous environment of the concrete depth of water, promptly can realize reliable pressurized gas sealing; (2) can promptly open and close to change the welding procedure test specimen; (3) can under various pressure ranks, work reliable and securely; Or the like.
At present, the general high pressure welding experimental cabin that has the fast open locking device that uses can satisfy this requirement preferably, but, opening the end cap operation when may there be low residual pressure in the inherence, cabin is danger close, tend to lead to a disaster, this just requires to be provided with a safety interlocking again, and container can boost after it made quick operating valve (lid) arrive the predetermined work position, just can open quick operating valve (lid) after container internal pressure discharges fully, and the warning device synchronous with above-mentioned action preferably can be arranged.Opening now common in the pressure vessel industries soon only is a common manual safety interlock to be installed even just not to be had safety interlocking at all, its resistance to motion that can provide often is difficult to contend with some driving force, therefore because accident in violation of rules and regulations still often appears in aspects such as operator's carelessness.
The model utility content
The purpose of this utility model provides a kind of safety interlocking that is applicable to mesohigh, large-diameter pressure vessel, particularly dry welded high pressure test compartment.
For achieving the above object, the utility model is taked technological scheme: a kind of safety interlocking of dry welded high pressure test compartment, it includes: one takes over, it is arranged near the fast open locking device of described dry welded high pressure test compartment the cabin body, and should take over and cabin body internal communication: a ball valve, it is connected in the described adapter; One discharge pipe, it is connected on the described ball valve; One warning device, it is arranged on the described discharge pipe; One supporting frame, it is arranged between described adapter and the fast open locking device on the body of cabin; One locating stud, it is slidingly installed on the support frame as described above, and an end of this locating stud is articulated on " ヘ " type spanner of described ball valve, the receiving hole that the other end is offered on the fast open locking device.
In practical operation, described adapter can be arranged near the clip circle of described dry welded high pressure test compartment fast open locking device, and corresponding locating stud is provided with described receiving hole on the clip circle.In addition, can be connected by flange between described adapter and the ball valve, also can be connected between described ball valve and the discharge pipe by flange.
In the safety interlocking of above-mentioned dry welded high pressure test compartment, support frame as described above is " " type, and the one end is fixed on the body of cabin, and the other end is fixed on the ball valve.In addition, the warning device place of described discharge pipe also is provided with a reduction valve.
The utility model is owing to take above design, and it has the following advantages:
1, in the utility model, after the clip circle was rotated in place, " ヘ " type spanner of the manual rotary ball valve of operator cut out ball valve, spanner drives the locating stud displacement simultaneously, locating stud is entered in the receiving hole of clip circle, at this moment could be to inflating in the body of cabin, if ball valve is not closed just to inflating in the body of cabin, gas can let out from ball valve, if and the clip circle is not rotated in place, locating stud just can not enter in the receiving hole of clip circle so, and ball valve is closed.
2, make locating stud enter the receiving hole of clip circle after, locating stud just can stop clip circle revolution, also can't make the rotation of clip circle even misoperation occurs when having guaranteed work, avoids having an accident.
3, when finishing, welding procedure test need open fast beginning during lid, gas in the at first necessary emptying high pressure welding experimental cabin, when air pressure becomes normal pressure, " ヘ " type spanner of manual unlocking ball valve, thereby ball valve is opened, also made locating stud withdraw from the receiving hole of clip circle simultaneously; If also have compressed gas in the high pressure welding experimental cabin this moment, compressed gas is just discharged through adapter, ball valve, discharge pipe and reduction valve and alarm hooter so, police whistle sound also sounds thereupon, have only when gas pressure in the high pressure welding experimental cabin is reduced to zero, siren breath sound, can rotate the clip circle this moment, restarts fast beginning lid the cabin body is opened.
4, the utility model is simple in structure, with low cost and effectively avoid having an accident because of misoperation.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
As shown in Figure 1, be the safety interlocking of a kind of dry welded high pressure test compartment that the utility model provides, it includes:
One takes over 1, and it is arranged near the dry welded high pressure test compartment fast open locking device the cabin body 2, and take over 1 with cabin body 2 internal communication;
