Abstract

The utility model relates to a leaking stoppage fixture which is mainly used for disposing leakage accidents of a movable pressure container, particularly a movable pressure container leaking stoppage fixture for disposing large leakage accidents of various leakage points of a safety valve or a flange of the movable pressure container. The utility model is a cylindrical device which can be used for covering the whole safety valve or the flange. The upper part of the utility model adopts the same kinds of steel plates, and the upper part is sealed by a steel body welding technique. The center of each steel plate is welded with an air discharge valve, and the purpose of pressure relief can be obtained. Two leading chain grooves are symmetrically welded on the steel plate, so that leading chains can be fixed. Both sides of the utility model are symmetrically welded with two handles, so that the use is convenient in the process of operation. The utility model has the advantages that whatever the leakage pressure is big and the leakage point positions are complicated, the leakage accidents of the safety valve of the movable pressure container can be quickly and effectively disposed by the stoppage fixture. The utility model has the characteristics of convenience, practicality, convenient operation, etc.

Description

Moving pressure container leak stopping anchor clamps

Affiliated technical field

The utility model is mainly used in a kind of leak stopping anchor clamps of disposing the moving pressure container leakage accident, especially can dispose the moving pressure container leak stopping anchor clamps of the bigger leakage accident of the multiple leakage point at moving pressure container safety valve or flange place.

Background technique

As everyone knows, present leak stopper mainly contains sealed type, binding type, pouring-in, magnetic pressure type, stick type.Majority all is used to dispose the container of comparison rule and the leakage accident of pipeline in the middle of these leak stopping modes, is not suitable for erose leak position, for example, and the safety valve place of lng tanker.And above-described leak stopping form all needs colloid to be used basically, and the costing an arm and a leg of colloid, the shelf-life short (generally about 1 year), in the leak stopping process, use very inconveniently, and need several operator's cooperations.In addition, the pressure range that these leak stoppers use is mostly below 1.0Mpa, and most of moving pressure container leakage accident finally will carry out " tank switching " and handles, and " tank switching " technical requirements is generally operated more than 1.3Mpa.So present leak stopper is difficult to the leak stopping work of the safety valve place leakage of competent moving pressure container.

Summary of the invention

In order to overcome the deficiency that existing fire-fighting leak stopper can not satisfy moving pressure container leak stopping job requirement, the purpose of this utility model is, a kind of moving pressure container leak stopping anchor clamps are provided, these anchor clamps can not only be disposed the leakage accident at various moving pressure container safety valves or flange place easily, and can satisfy the operation requirement of pressure more than 1.3Mpa.

The technological scheme that its technical problem that solves the utility model adopts is: according to the relevant criterion of moving pressure container in " GB ", design a cylinder-shaped device that safety valve or flange all can be covered.The radian of this bottom of device design is the radian at tank body of container safety valve or flange place, reaches the purpose of sealing; With steel plate of the same type, adopt steel body welding technique on the top of installing, top seal is lived, unload air valve, reach the purpose of release, on steel plate, be symmetrically welded two guide chain grooves, so that fixedly lead chain one of the center of steel plate welding; At two handles of bilateral symmetry welding of device, so that convenient use during operation.The material that this device adopted is the Q235 steel, and leading chain is brass chain, and the thickness of seal rubber pad is more than 5 millimeters.Usually the pressure of pressurized container leakage point is 1-2Mpa.This device can all cover the valve or the flange at leakage point place, so be not subjected to the restriction of the factors such as shape, size, position of leakage point, after gas leakage or liquid are filled into device inside,, thereby pressure is reduced with the area of contact increase of device.By the means of this principle and above structure and the material of use, the purpose that just can reach the leakage accident of disposing various moving pressure container safety valves or flange place and prevent to explode.

The utility model has the advantages that the pressure that no matter leaks has much, how complicated the position of leakage point is, and these anchor clamps can rapidly, effectively be disposed the leakage accident at moving pressure container safety valve place.Characteristics such as have conveniently, practical, easy to operate.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

In Fig. 1, select the cylindrical body 4 of respective diameters according to the flange size (" GB " has specific requirement) at pressure vessel relief valve place, round barrel cover 5 is welded to the top of

cylindrical body

4,2 guide chain grooves 2 of welding of symmetry on round barrel cover 5, drill through corresponding circular hole at the center of round barrel cover 5, in pressure-relief valve 1 welding, last 2 handles 3 of monosymmetric welding at cylindrical body 4.

In Fig. 3, the bottom car of cylindrical body 4 is become the arc tube 6 of relevant radii according to pressure volume pot body model (" GB " has specific requirement).

The material of cylindrical body 4 and round barrel cover 5 is the Q235 steel; Lead chain 8 and be brass chain; Rubber cushion 9 thickness are more than 5 millimeters.

When specifically carrying out the leak stopping operation, earlier preprepared rubber cushion 9 is cut, place leak, simultaneously, rapidly these anchor clamps are placed into the position (note: the arc 6 that must guarantee the anchor clamps bottom surface is consistent with the cambered surface direction of pressurized container) that covers leakage on the rubber cushion and open anchor clamps pressure-relief valve 1.
