Abstract

The utility model relates to a device for safely dismounting the valve of a cylinder in danger, composed of a housing (4), a gas delivery tube (12), a clamping lever (5) whose body is arranged in the cavity of the housing (4), and spirally connected with the housing (4), etc. The housing (4) is provided with screw thread (14) spirally used for connecting with a gas cylinder valve seat (9); the geometry shape of the cross section of a valve body (7) is similar to the cross section of the lower part of the clamping lever (5), the valve body (7) is sheathed on the clamping lever (5), and the geometry shape is an opening shape which plays a clamping action in rotating. The utility model can disassemble a cylinder valve in a closed condition, and safely draw out the gas of a cylinder in danger. The utility model is suitable for treating a low pressure gas cylinderl.

Description

Danger bottle cylinder valve safety stripping attachment

The utility model relates to the tapping equipment of gas storage container and makes the field, and the tapping equipment that especially relates to the danger bottle that is used for gas cylinder is made the field.

In processes such as the can of gas cylinder, transportation, loading and unloading, use, liquid chlorine gas cylinder for example, owing to fill the chemical corrosivity of gas chlorine, gas cylinder cylinder valve generation corrosion and can not opening; Perhaps because the gas cylinder cylinder valve can not be opened by mechanical damage.What fill in the gas cylinder is the liquid chlorine with height toxicity, and its nominal operating pressure can reach 2MPa.For this class can not normally discharge, the filling gas poisonous and harmful, have the gas cylinder of certain pressure, generally be referred to as the danger bottle.The processing of liquid chlorine danger bottle generally is that operator are with respirator,, with the loosening cylinder valve valve body of spanner chlorine is discharged in the appointed place.Its shortcoming is that operation inconvenience, shortage Security, gas can't be collected, befouling environment.

Task of the present utility model provides a kind of danger bottle cylinder valve safety stripping attachment, and it can dismantle cylinder valve under encapsulation situations, and gas to specified containers is collected in the derivation danger bottle.

Task of the present utility model is finished by the following technical programs: a kind of danger bottle cylinder valve safety stripping attachment, stretched out by housing, the gas eduction tube that is communicated with the housing inner chamber and top mainly that housing, main body place the housing inner chamber, the supporting rod that connects with the housing spiral is formed; The lower inside of housing is provided with the screw thread that gas cylinder valve seat spiral connects; The supporting rod lower cross section for similar to the valve body cross-sectional geometry, with the valve body chuck therebetween, play the opening shape of clamping action when rotating.

After adopting technique scheme, because housing top connects with the supporting rod spiral, the bottom connects with gas cylinder valve seat spiral, therefore, the housing inner chamber forms the enclosed space with unique gas eduction tube path; When supporting rod was subjected to external force to do as the spiral ascending motion, the valve body that is held was in company with doing the spiral ascending motion together, and from gas cylinder valve seat that its spiral connects deviate from, the gas discharge in the gas cylinder is delivered to specified containers through gas eduction tube.Like this, the cylinder valve dismounting is able to carry out under closure state, and gas exports to specified containers in the bottle of will endangering, and is collected; Operator needn't wear the gas defence instrument and just can safely danger bottle gas be derived, and have got rid of any discharging of danger bottle gas with the inflammable characteristic of toxicity and the befouling environment that causes, person poultry poisoning, all hazards such as fire accident.

Fig. 1 is an embodiment's of the utility model a phantom;

Fig. 2 is the amplification view along A-A direction supporting rod shown in Figure 1.

Below in conjunction with accompanying drawing the utility model is elaborated.

Housing 4 and supporting rod 5 adopt quality carbon steel to make.The screw thread 14 of the lower inside of housing 4 matches with the screw thread that is welded on gas cylinder valve seat 9 outers on the gas cylinder 10, and the screw thread of gas cylinder valve seat 9 outers is that the spiral for the gas cylinder valve protection cap connects and is provided with.The ring packing end face 13 that the lower inside of housing 4 is provided with utilizes housing 4 gentle cylinder valve seat 9 spirals to connect the impacting force that produces sealing gasket 8 is compressed, and further enhanced leaktightness performance.The material of sealing gasket 8 is determined according to the gas cylinder medium, as for chlorine, can be adopted materials such as asbestos slate, asbestos packing sheet, fluoroplastic.The screw thread 2 on housing 4 tops matches with screw thread 3 on the supporting rod 5, its thread parameter such as pitch, thread profile shape etc., should consider consistent with cylinder valve valve root screw thread 15, in order to synergy movement.Part was socketed with a handwheel 1 beyond supporting rod 5 stretched out housing 4, and supporting rod 5 tops are the packing seal employing gland nut type packing seal of the top setting of housing 4 to housing 4 overhanging positions.

In conjunction with Fig. 2, present embodiment is under the foursquare situation at the cross section of valve body 7, the lower cross section of supporting rod 5 makes square similarly, and in openings at one side, the stero shape of supporting rod 5 bottoms promptly is an opening, opening simultaneously is in order to vacate the spatial position of cylinder valve outlet 6, its excess-three face correspondence with valve body 7 chucks therebetween, should keep certain interval during chuck, can be in order to supporting rod 5 freely from putting down, with valve body 7 chucks, simultaneously, in the time of must satisfy rotating again to the clamping action of valve body 7.The height of clamp face can be taken as consistent with the height of valve body 7.At the cross section of valve body 7 is to vacate under the regular hexagon situation under the prerequisite of spatial position of cylinder valve outlet 6, and supporting rod 5 sub-body shapes can be made the class formula and handle.Gas eduction tube 12 is welded on the housing 4, communicates with housing 4 inner chambers, and the pipeline of gas eduction tube 12 is provided with valve 11.

When endangering bottle cylinder valve disassembling section, take off valve protection cap, unload the outer gland of packing on the lower bottle valve, add sealing gasket 8, housing 4 and gas cylinder valve seat 9 are connected as spiral, simultaneously, supporting rod 5 correspondences are moved handwheel 1 rotation with valve body 7 chucks therebetween, and supporting rod 5 rotations upwards, the valve body 7 that is held rotates upwards simultaneously, valve body 7 breaks away from from gas cylinder valve seat 9 gradually, and the gas in the gas cylinder 10 is discharged, and enters housing 4 inner chambers, through gas eduction tube 12, valve 11 is directed at specified containers again.
