Abstract
A double-material hole sealing bag comprises an A material room filed with a polyurethane A material and a B material room filled with a polyurethane B material, wherein sealing rooms are disposed between the A material room and the B material room, the sealing rooms are divided into a middle sealing room and a side sealing room, sealing strength of the middle sealing room is lower than the sealing strength of the side sealing room, a gas room and a gas room hole are disposed in the middle of the middle sealing room, one side of the side sealing room which is close to the center of the gas room forms an arch shape and an arc convex part faces towards the gas room center. When high-pressure gas is filled into the gas room, the high-pressure gas will break through the middle sealing room and then communicate the A material room and the B material room. In this way, both the polyurethane A and B materials can be mixed and mixing time of the A and B materials is controlled by controlling rushing time of the high-pressure gas into the gas room, so that the polyurethane A and B materials can be mixed at regular time.
Description
Technical field
The present invention relates to a kind of extra quality hole sealing bag, be especially a kind ofly applicable to carry out under coal mine the extra quality hole sealing bag that sealing of hole is used.
Background technology
At present, when mine carries out gas drainage under suction or gas pressure measurement work, what port closing used mostly is polyurethane material.While using polyurethane, need first A, two kinds of polyurethane materials of B to be poured on towel, then the two is mixed, be in charge of by being bundled into four, then fill in boring.Because the reaction time of polyurethane is limited, thereby cause polyurethane can not deliver to assigned address, can not reach like this hole sealing depth of appointment; Carry out so the as easy as rolling off a log part such as health or arm that makes in the shutoff course of work and directly touch polyurethane material, the healthy of staff impacted simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the weak point in prior art, and a kind of simple in structure, device of mixing when realizing polyurethane A, B and anticipating is provided.
For achieving the above object, extra quality hole sealing bag of the present utility model, comprise the A material chamber of polyurethane A material, the B material chamber that polyurethane B material is housed are housed, between A material chamber and B material chamber, be provided with seal area, seal area is divided into He Bian seal area, seal area, middle part, and the sealing intensity of seal area, middle part is lower than the sealing intensity of seal area, limit, and described middle part, seal area, middle part is provided with air chamber and air chamber mouth, seal area, limit becomes circular-arc near air chamber center one side, and circular arc projection is towards air chamber center.
The physical dimension of described A material chamber and B material chamber is identical, the major axis symmetry of both and air chamber.
The width of described seal area, middle part is 1/5～1/3 of A material chamber width.
Described air chamber ovalize, diameter is 2/3～4/5 of seal area, middle part width.
The width that described seal area, limit is positioned at surrounding part is 1/2 of air chamber minor axis.
Described air chamber mouth is by polytetrafluoroethylene (PTFE) or have flexible material and make.
Beneficial effect: the utility model expects that by A chamber, B material chamber are by A, two kinds of polyurethane material packing of B, the effect of a sealing plane of weakness is played in seal area, middle part, be connected with extraneous high-pressure air source by air chamber, and air chamber sealing plane of weakness around, the timing that can realize polyurethane A, B material mixes, and can not deliver to a difficult problem of specifying hole sealing depth thereby solved polyurethane A, B material.Can realize and being connected fast with plastics sebific duct by air chamber mouth, like this can be conveniently and being connected of extraneous high-pressure air source.In the time being filled with gases at high pressure in air chamber, high pressure gas cognition is broken through seal area, middle part, thereby A is expected to chamber and B material chamber are communicated with.Like this, the A of polyurethane, B material just may be mixed together.Therefore, by controlling the time of pouring of air chamber inner high voltage gas, just can control the incorporation time of A, B material, thereby reach the object that timing mixes polyurethane A, B material.It is simple in structure, easy to use, has practicality widely.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-A expects chamber; 2-B expects chamber; Seal area, 3-limit; Seal area, 4-middle part; 5-air chamber mouth; 6-air chamber.
Detailed description of the invention
Below in conjunction with accompanying drawing, utility model embodiment is further described:
As described in Figure, extra quality hole sealing bag of the present utility model, is mainly made up of A material chamber 1, B material chamber 2, seal area, limit 3, seal area, middle part 4, air chamber mouth 5, air chamber 6.Extra quality hole sealing bag is flexible pouch, and the A material of polyurethane is housed in A material chamber 1, and the B material of polyurethane is housed in B material chamber 2, and the physical dimension of described A material chamber 1 and B material chamber 2 is identical, the major axis symmetry of both and air chamber 6.Between A material chamber 1 and B material chamber 2, be provided with seal area, seal area is divided into seal area 4, middle part and seal area, limit 3, and the sealing intensity of seal area, middle part 4 is lower than the sealing intensity of seal area, limit 3, and the width of described seal area, middle part 4 is 1/5～1/3 of A material chamber 1 width; The width that described seal area, limit 3 is positioned at surrounding part is 1/2 of air chamber 6 minor axises.Described 4 middle parts, seal area, middle part are provided with air chamber 6 and air chamber mouth 5, and described air chamber mouth 5 is by polytetrafluoroethylene (PTFE) or have flexible material and make, and can realize and being connected fast with plastics sebific duct, like this can be conveniently and being connected of extraneous high-pressure air source.Seal area, limit 3 becomes circular-arc near air chamber 6 center one sides, and circular arc projection is towards air chamber 6 centers.Described air chamber 6 ovalizes, diameter is 2/3～4/5 of seal area, middle part 4 width.
Before use, first to check the tightness of extra quality hole sealing bag, leak the extra quality hole sealing bag that need to more renew if any polyurethane.If tightness is good, there is not leakage problem, just can this device be tied up four and is in charge of with adhesive tape or rope, then be connected with air chamber mouth 5 with plastics sebific duct, plastics sebific duct can be realized quick connection with air chamber mouth 5, will ensure both tightness and connection reliability simultaneously.Link together by being in charge of joint one joint by four, just this extra quality hole sealing bag can be delivered to the assigned address of boring, by pressing wind or inflator to be connected plastics sebific duct and down-hole, thereby just gases at high pressure can be able to be injected in air chamber 6.In the time being filled with gases at high pressure in air chamber 6, high pressure gas cognition is broken through seal area, middle part 4, thereby A is expected to chamber 1 and B material chamber 2 are communicated with.Like this, the A of polyurethane, B material just may be mixed together, thereby reaches the object that timing mixes polyurethane A, B material.
