1. gas pipe line pressure is limited to some extent, when pipeline pressure surpassed 10KPa, little stopper can't stop a leak, and can be blown;
2. stopper can not be fully and the engagement of leak place, poor sealing;
3. when gas temperature was higher, when reaching more than 120 ℃ as gas temperature, wood materials was difficult to bear long coal gas stream and washes away, and welding packing operation must be carried out fast;
4. the stopper size will be complementary with leak, manipulates inconvenience.
Publication number is CN1311410, open day is September 5 calendar year 2001, the patent documentation that name is called " belt leak stopping device " discloses a kind of belt leak stopping device, as shown in Figure 1, this leak stoppers comprises hydraulic hand-pump 1, high pressure hose 2, high pressure leak stopping colloid-injecting gun 3, anchor clamps 4, leak stopping band 5 and leak stopping glue 6.During work, according to the leak point size, select corresponding anchor clamps 4 and leak stopping band 5, the rapid pipe joint of leak stopping band 5 is buckled on the base plate, and leak stopping band 5 is fixed on the screw to be tightened, and belt leak stopping device anchor clamps 4 are solid on flange, the corresponding glue rod of in colloid-injecting gun body 3, packing into, open the rubber injecting valve switch then, start oil pump, leakage place injecting glue.But the pipeline that above-mentioned belt leak stopping device can't be applied to have certain internal pressure and uniform temperature.
Summary of the invention
The purpose of this utility model provides a kind of gas pipe line leakage-baffling device, this device can solve at gas pipe line pressure under the big or gas temperature conditions of higher can't leak stopping problem, thereby fundamentally stop potential safety hazard in the production process.
Technical conceive of the present utility model is as follows: at first by one " individual " font drag hook silicone rubber is fastened on the tube wall, when making pipeline pressure greater than 10KPa, leakage-baffling device still can effectively use; Next adopts silicone rubber and metal construction high temperature resistant, good airproof performance combined, and gas pipe line is carried out leak stopping, makes this device can be applied in the hot environment below 350 ℃; At last, this device is undertaken fastening by nut, and fitting operation is convenient.
For achieving the above object, the utility model provides a kind of gas pipe line leakage-baffling device, comprises that one is used for the frustum type lost circulation plug of blocking pipe leakage hole, comprises in addition:
One fixing drag hook comprises a resilient barb, and a shank, and the head end of described shank is fixedlyed connected with resilient barb, and the shank tail end is provided with outside thread, and described frustum type lost circulation plug center has through hole, and the frustum type lost circulation plug is placed on the described shank by its through hole;
One baffle ring is placed on the described shank, is connected with the tail end end face contact of described frustum type lost circulation plug, is used for described frustum type lost circulation plug is carried out axially locating;
One nut is connected with described baffle ring contact, and is threaded with described shank tail end.
Said fixing drag hook, baffle ring and nut are used, and the frustum type lost circulation plug can be fixed on the tube wall firmly.
Preferably, described gas pipe line leakage-baffling device also comprises a sleeve pipe, and described sleeve pipe is placed on the described shank, described frustum type lost circulation plug is placed in the head end of sleeve pipe, described baffle ring is placed on the described sleeve pipe fixedlys connected with sleeve pipe, and the tail end of sleeve pipe is provided with a boss, and described nut is connected with the boss contact.This sleeve pipe can be realized the gas in the pipeline is drawn, and is convenient to lost circulation plug is injected leak.
Preferably, described frustum type lost circulation plug is the silicone rubber lost circulation plug.Because silicone rubber has certain elasticity, and is convenient to be processed into the big frustum type in the little rear end of front end, the shape of simultaneous adaptation leak is so use the silicone rubber lost circulation plug can realize and the combining closely of leak.
Preferably, be provided with rubber sheet gasket between the boss of described sleeve pipe tail end and the described nut.
Preferably, described sleeve pipe is a metal sleeve.
The utility model is owing to adopted above technological scheme, make it compared with prior art, can be applicable to that gas temperature is below 350 ℃, the gas pipe line leak stopping that gas pressure 10KPa is above, and can realize online leak stopping, thereby make that blast furnace gas pipeline leak stopping work is convenient, reduced operator's labor intensity, strengthened the Security of leak stopping.
