Abstract
The utility model relates to a kind of location Washdown type spacer, is provided with woven bag, complex pocket, charging connector, valve inside, it is characterized in that: described valve inside is by charging connector, and charging connector is welded on complex pocket, and complex pocket is contained in inside woven bag.The utility model design is more reasonable, and annular holddown groove is positioned at charging connector inside, and the pneumatic head coordinated with charging connector is provided with retainer ring, avoids the installation inconvenience that pneumatic head adopts inside fixation slot to bring, easily by problems such as earth clog.
Description
Technical field
The utility model relates to a kind of spacer, specifically a kind of location Washdown type spacer.
Background technology
Easy to operate owing to flinging spacer; the feature such as environmental protection, safety; accept by a lot of large-scale mines; and the use of scale, but in the process used, because gas-charging connection is wanted inevitably and slag in ground or hole and mud contacts; because traditional gas-charging connection is circular hole; more easily fill in mud and slag, and be not easy process especially, the production for scene causes very large impact.
Summary of the invention
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of location Washdown type spacer simple and reasonable for structure, by the rational modification to charging connector, annular holddown groove is placed on the inside of charging connector.
The utility model taked technical scheme that solves the problem is: a kind of location Washdown type spacer, be provided with woven bag, complex pocket, charging connector, valve inside, it is characterized in that: described woven bag is located at outermost layer, described complex pocket is arranged in described woven bag, and described charging connector is located at the side of spacer, and complex pocket is led in one end, the other end leads to space outerpace, its inside is provided with annular holddown groove, and described valve inside is arranged on one end that charging connector leads to complex pocket, and is provided with opening and closing device.
Charging connector described in the utility model be with the pneumatic head of outside with the use of, how described pneumatic head there are retainer ring and sealing ring, when pneumatic head inserts charging connector, retainer ring on pneumatic head is stuck on the annular holddown groove on charging connector, and the sealing ring on pneumatic head and the inwall of charging connector are combined closely.
The utility model is owing to taking said structure, namely gas-charging connection can be fixed by the annular holddown groove of charging connector inside, changing charging connector in the past adopts external stability ring to be fixed on inside the annular holddown groove of pneumatic head, so, easy and simple to handle, gas-charging connection is not easy to be clogged by slag, improves efficiency and the convenience of production operation, is a kind of product being particularly suitable for mine mining field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is the structural representation of charging connector of the present utility model;
Fig. 4 is charging connector of the present utility model and pneumatic head syndeton schematic diagram.
Be labeled as in figure: 1. woven bag, 2. complex pocket, 3. charging connector, 4. valve inside, 5. annular holddown groove, 6. pneumatic head, 7. retainer ring, 8. sealing ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model relates to a kind of location Washdown type spacer, be provided with woven bag 1, complex pocket 2, deflating valve 3, valve inside 4, it is characterized in that: by there being valve inside 4 on described charging connector 3, charging connector 3 is welded on complex pocket 2, and complex pocket 2 is contained in inside woven bag 1.Pneumatic head 6 inserts inside charging connector, ring-shaped fixing rings 7 above pneumatic head 6 is just stuck in inside the annular holddown groove 5 on charging connector 3, sealing ring 8 on pneumatic head can contact with the inner hole wall of charging connector 3, guarantee can not be leaked gas, the snap switch of the front end pressing valve inside 4 of pneumatic head simultaneously, valve inside 4 is just in the state of ventilation, now can fill spacer inflation to positioning straight.
When the utility model uses, directly pneumatic head is connected with the charging connector flung on spacer just passable, method of operating except than common fling spacer simple and convenient except, topmost feature be embodied in charging connector annular holddown groove in the inside of charging connector, change retainer ring in the past in the outside of charging connector, to be attached thereto the pneumatic head connect be the structure of interpolation type, solves in the process of installing and using the difficult problem easily entering sand because pneumatic head is interpolation type structure and be not easy to process and charging connector easily breaks inside pneumatic head.
