Abstract
The utility model discloses a leak stopper of a tank, which consists of a sealing shell 1, a base 2 and a screw 3; wherein, the bottom of the sealing shell 1 is provided and hermetically connected with the base 2, a screw hole 4 is arranged at the periphery of the top of the sealing shell 1, the screw 3 is inserted into the screw hole 4; the bottom of the sealing shell 1 is provided with a seal groove into which a sealing ring is embedded. The leak stopper of the tank has reasonable design and simple structure, is easy for manufacturing and convenient for operation, is fast, safe and efficient in emergent leak stoppage, and is suitable for being used once a safety valve of a pressure vessel which is filled with hazardous chemical has leakage.
Description
Technical field
The utility model relates to a kind of groove jar leak stopping device, carries out the band indent jar leak stopping device that emergency management and rescue are used when specifically the pressurized container that holds inflammable and explosive hazardous chemical in static or the transportation being taken place to leak.
Background technique
Hazardous chemical is gas or a liquid inflammable, explosive, poisonous, that be corrosive, be harmful to, the pressurized container that holds hazardous chemical has a safety valve at least, various safety valves are owing to manufacture the intrinsic defect of material, damage in the not good and long-term work process of the quality manufactured of processing, and the effect of the high low temperature of burn into, the influence of vibration and factor such as collision is broken, crack or loss of seal, all can cause the leakage of hazardous chemical, if its consequence of untimely leak stopping is hardly imaginable.At present, the blocking method that people generally adopt mainly is a plugging gun, glue is injected leakage seam place, utilize external force to fix, because this plugging gun of particularity at safety valve position can not effectively and fast be blocked the slit, after being exactly the complete or drainage of high-risk chemical leakage fully in addition, welding is leaked seam or is changed safety valve; When other position takes place to leak, also be to adopt said method.
Summary of the invention
The purpose of this utility model aims to provide a kind of quick, effective, the groove jar leak stopping device of safety.
To achieve these goals, groove jar leak stopping device of the present utility model is made up of seal closure, screw rod and base, the bottom of described seal closure is provided with base and is tightly connected, the seal closure bottom is provided with seal groove, seal ring embeds in the seal groove, the seal closure top perimeter is provided with screw, and screw rod inserts in the screw, and screw tip seals with nut; The seal closure center of top is provided with pore, and pipeline is corresponding with pore fixedly connected, and the pipeline upper end connects threeway, and two outlets of threeway connect Decompression valves and pressure gauge respectively; Base diameter is greater than the diameter of seal closure, and base is set to the arc or the shape of a saddle, perhaps with the corresponding shape of the profile at pressure vessel relief valve position; The screw of seal closure top perimeter and the corresponding setting of screw on the pressure vessel relief valve.
Groove jar leak stopping device of the present utility model compared with prior art has following excellent effect:
1, quick: on pressure vessel relief valve, the screw of seal closure top perimeter is corresponding with the screw of pressurized container tank car safety valve with closing cap, inserts screw rod, screws the back and is connected as a single entity with pressurized container;
2, safety, effective: the base shape of seal closure bottom is corresponding with the profile at pressure vessel relief valve position, seal ring in the seal closure base channel is fully with leakage and external isolation, effectively prevented leakage, pressure gauge on the seal closure top duct and Decompression valves have guaranteed the Security of leak stopping;
3, reasonable in design, simple in structure, be easy to manufacture, easy to operate;
4, reduced cost;
5, direct pressure sealing.
Description of drawings
Fig. 1 is the floor map of the utility model groove jar leak stopping device.
Wherein: 1, be seal closure; 2, be base; 3, be screw rod; 4, be screw; 5, be pipeline; 6, be threeway; 7, be Decompression valves; 8, be pressure gauge.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Groove jar leak stopping device shown in Figure 1 is made up of seal closure 1, base 2 and screw rod 3, and the bottom of seal closure 1 is provided with base 2, and makes seal closure 1 and base 2 be linked as integral body, and the top perimeter of seal closure 1 is provided with four screws 4, and screw rod 3 inserts in the screw 4; The center of top of seal closure 1 is provided with a pore, and pipeline 5 is fixedlyed connected with the pore sealed type, and the upper end of pipeline 5 connects threeway 6, and two outlets of threeway 6 connect Decompression valves 7 and pressure gauge 8 respectively; Seal closure 1 bottom is provided with seal groove, and seal ring embeds in the seal groove; The internal diameter of seal closure 1 is greater than the diameter of pressure vessel relief valve, and the diameter of base 2 is greater than the diameter of seal closure 1; Four screws 4 that seal closure 1 top perimeter is provided with are corresponding with the screw on the pressure vessel relief valve, be convenient to screw rod 3 pressurized container and groove jar leak stopping device of the present utility model are connected as a single entity; Base 2 can be set to arc, the shape of a saddle or with the corresponding shape of the profile at pressure vessel relief valve position coincide so that base 2 contacts with the pressure vessel relief valve position, make the maximum sealing usefulness of seal ring performance in the seal closure 1 bottom seal groove.
