Abstract
The utility model relates to a safety remover for the valve and the plug screw of a gas cylinder, comprising a housing, a gas delivery tube communicated with the housing, a screw rod whose top is extend from the housing, the main body of the screw rod is arranged in the cavity of the housing, and the screw rod is spirally connected with the housing, and a clamping head spirally connected with the screw rod. The clamping part of the cross section of the lower part of the clamping head forms a geometry shape which is similar with a cylinder valve body or the cross section of a screw plug, and the shape plays a clamping effect in the clamping head rotating; screw-threads connected with a cylinder valve base or a screw plug base are respectively arranged at the part of the housing and the outer side surface of the housing. The utility model has the advantages of safe cylinder valve and screw plug disassembly, mounting matched with the external screw-thread and the internal screw-thread of the cylinder valve base or the screw plug base.
Description
The utility model belongs to gas cylinder fault treatment mechanical device, in particular for the mechanical device of dismounting cylinder valve or plug screw.
Chinese patent literature discloses a kind of " danger bottle cylinder valve safety stripping attachment " (applying date: 960510; Application number: 96233083.3), it leaks or stops up for cylinder valve and causes gas can not normally derive this class gas cylinder fault of (becoming right bottle), can get rid of safely and effectively.But its shortcoming is one: the gas cylinder plug screw leaks, and it is helpless; Its two: the screw thread of its lower housing portion inboard is with the threads engaged in the cylinder valve valve seat outside, because the screw thread in the cylinder valve valve seat or the plug screw obturating plug outside is subject to mechanical damage, often causes when using, and above-mentioned stripping attachment housing can not be installed with it smoothly.Its three: its housing is installed (the two spiral is connected) on the cylinder valve valve seat need relatively large instrument as more than 20 inches pipe tongs, the outstanding sense inconvenience of operation.
Task of the present utility model be to overcome above-mentioned deficiency and a kind of gas cylinder cylinder valve, plug screw safety stripping attachment are provided, it both can dismantle cylinder valve safely, can dismantle plug screw safely; The screw thread that it cooperates with cylinder valve valve seat or plug screw obturating plug is provided with simultaneously in the inside and outside side of lower housing portion.
Task of the present utility model is realized by the following technical programs: a kind of gas cylinder cylinder valve, plug screw safety stripping attachment, mainly stretched out by housing, the gas eduction tube that is communicated with the housing inner chamber and top that housing, main body place the housing inner chamber, the supporting rod that connects with the housing spiral is formed; Lower housing portion is provided with the screw thread that connects with cylinder valve valve seat or plug screw obturating plug spiral; Above-mentioned supporting rod by the screw rod that connects by thread helix with housing and with screw rod by another thread helix connect, the detachable gripping head of changing forms, this gripping head has two kinds of structural types: perhaps the retained part of gripping head lower cross section for similar to cylinder valve valve body cross-sectional geometry, with its chuck therebetween, play the shape of clamping action during rotation; Perhaps the retained part of gripping head lower cross section for similar to the plug screw cross-sectional geometry, with its chuck therebetween, play the shape of clamping action when rotating; The screw thread that described housing connects with cylinder valve valve seat or plug screw obturating plug spiral is arranged on the inner side surface and outer side surface of lower housing portion simultaneously.
According to above technological scheme, former supporting rod changes screw rod and detachable replacing formula gripping head into, and kit both can be dismantled cylinder valve safely, can dismantle plug screw safely again; The inside and outside side of lower housing portion all is provided with screw thread, both can cooperate with the outside screw of cylinder valve valve seat or plug screw obturating plug, can cooperate with its inside thread again, because having, the inside thread of cylinder valve valve seat or plug screw obturating plug do not subject to mechanical damage, be easy to advantages such as oiling maintenance, and more extensive in the use.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sectional view of the utility model user mode when the dismounting cylinder valve;
Fig. 2 is the sectional drawing along the A-A line shown in Figure 1;
Fig. 3 is the sectional view of the utility model user mode when the dismounting plug screw;
Fig. 4 is the sectional drawing along the B-B line shown in Figure 3;
Among Fig. 1-Fig. 4,1. handwheel; 2. screw rod; 3.3a screw thread; 4. half hole; 5. housing; 6.6a gripping head; 7. cylinder valve valve body; 8. sealing gasket; 9. cylinder valve valve seat; 9a plug screw obturating plug; 10. gas cylinder; 11. packing seal; 12. valve; 13. gas eduction tube; 14. screw thread; 15. ring packing end face; 16.16a screw thread; 17. plug screw.
Among Fig. 1, cylinder valve valve seat 9 is welded on the gas cylinder 10, the screw thread 14 that housing 5 is provided with by its underpart outer side surface connects with cylinder valve valve seat 9 spirals that (housing 5 lower inside surface are provided with screw thread simultaneously, do not draw among Fig. 1, this is a prior art above), the ring packing end face 15 of housing 5 bottoms is withheld on the sealing gasket 8 that places on the cylinder valve valve seat 9, thereby realizes tightness.Gas eduction tube 13 is communicated with housing 5 inner chambers, and gas eduction tube 13 is provided with valve 12.Form supporting rod by screw rod 2 and gripping head 6, gripping head 6 connects with screw rod 2 spirals by screw thread 3a, has detachable replaceability.Housing 5 is stretched out at screw rod 2 tops, and main body places housing 5 inner chambers, connects by screw thread 3 spirals with housing 5, and the top that screw rod 2 stretches out housing 5 is provided with handwheel 1.Screw rod 2 tops are provided with the packing seal 11 that prevents gas leakage through housing 5 overhanging positions, adopt conventional gland nut type packing seal.Offer 4～8 half holes 4 (Φ 12, hole depth 10cm) on the outer side surface of housing 5,, directly use iron rod, can screw in the cylinder valve valve seat 9 housing 5 fixing without other instrument.In conjunction with Fig. 2, the cross section of cylinder valve valve body 7 is a square, and the retained part of gripping head 6 lower cross section is similar squares of geometrical shape with it, and the retained part of gripping head 6 lower cross section can play clamping action during rotation with cylinder valve valve body 7 chucks therebetween.When the dismounting cylinder valve, turn handwheel 1, gripping head 6 are with 7 clampings of cylinder valve valve body and turn, and cylinder valve valve body 7 screws out from the screw thread 16 of cylinder valve valve root, until breaking away from cylinder valve valve seat 9.At last valve 12 is opened, gas in the gas cylinder 10 is imported the designated store container.Fig. 3 illustrates the situation of dismounting plug screw.The gripping head 6 of dismounting cylinder valve among Fig. 1 is unloaded, be replaced by the gripping head 6a (shown in Figure 3) of dismounting plug screw, in conjunction with Fig. 4, the cross section of plug screw 17 is a regular hexagon, the retained part of gripping head 6a lower cross section is the similar regular hexagon of geometrical shape with it, the retained part of gripping head 6a lower cross section can play clamping action during rotation with plug screw 17 chucks therebetween.When 17 cun of dismounting plug screws, turn handwheel 1, gripping head 6a are with plug screw 17 clampings and turn, and plug screw 17 screws out from the screw thread 16a of plug screw obturating plug 9a, until breaking away from plug screw obturating plug 9a.At last, valve 12 is opened, gas in the gas cylinder 10 is imported the designated store container.
