Abstract
The utility model relates to a blast-furnace cooling wall pipe test, in particular to a blast-furnace cooling wall pipe internal-expansion pressure testing device which is arranged on the pipeline opening of a blast-furnace cooling wall pipeline, and comprises a water feeding pipe, an elastic sleeve and a water feeding tube, wherein one end of the water feeding pipe is provided with a pipe socket with the outside diameter gradually prolonged, the pipe socket is connected with the cooling pipeline opening and fixed with the cooling pipe opening through a screw cap and a gasket, the inside diameter of the elastic sleeve is matched with the pipe socket connected with the cooling pipe opening, the elastic sleeve is sleeved with the pipe socket, and the water feeding tube is communicated with the other end of the water feeding pipe through a duplexing pipe. The utility model has reliable sealing property, simple structure and convenient test.
Description
Technical field
The test of the utility model blast furnace cooling stave pipeline relates in particular to the blast furnace cooling stave pipeline pressure testing device.
Background technology
Work pressure test is regarded as the important step in the blast furnace cooling stave fixing link always, and the quality of pressure test tool directly has influence on the quality and the progress of construction.Each production, installation unit mostly are the flange wafer type at the pressure test tool of usefulness at present, and its design is complicated, and poor sealing performance is in use very inconvenient, has a strong impact on construction speed and quality.Its installation method is: on the cooling stave pipeline lower flange is installed, fixes by bolt, sealing member is installed again, upper flange is installed at last, by fixing of bolt, thereby finish whole installations.The fastening effect that its shortcoming is embodied in is bad, and when carrying out upper flange bolt fastening, the lower flange bolt can be subjected to displacement usually, does not reach the effect of sealing.When carrying out the work pressure test of steel, two kinds of different cooling staves of copper especially at the same time, traditional pressure test tool does not just possess versatility, because the former is without screw thread but also do not have movable joint and flange not only, be the former top mouth of pipe, and the latter supplies in the mode that is processed into mouth of pipe rib-loop usually, because the softer employing bolting of material of copper will cause mouth of pipe rib-loop to damage.Obviously, traditional flange wafer type instrument can't use.
Summary of the invention
The utility model is intended to solve complicated, the pressure testing problem loaded down with trivial details, poor sealing performance of working of design in the blast furnace cooling stave fixing link, and expansion pressure testing device in a kind of blast furnace cooling stave pipeline is provided.The utility model sealing is reliable, simple in structure, convenient test.
The utility model is achieved in that
Expansion pressure testing device in a kind of blast furnace cooling stave pipeline, it is installed on the pipeline opening of blast furnace cooling stave pipeline, and it comprises:
A water inlet pipe, its end have that external diameter becomes gradually that big hydraucone connects the cooling tube road junction and by a nut and spacers on pipeline opening;
A resilient sleeve, the hydraucone of its internal diameter and connecting tube are complementary and are set on the hydraucone;
A water supply hose, it is communicated with by a transfer tube and the water inlet pipe the other end.
Expansion pressure testing device in the described blast furnace cooling stave pipeline, the other end of described water inlet pipe has outside screw, and described converting interface one end is the internal thread hole that is connected with water inlet pipe, and the other end is for connecting the Link Port of water supply hose.
Expansion pressure testing device in the described blast furnace cooling stave pipeline has a rotating handles on the body of described transfer tube.
The utility model sealing is reliable, simple in structure.The water inlet pipe hydraucone that puts resilient sleeve is filled in the mouth of pipe of cooling stave, with nut screwing clamping, allow pad compress resilient sleeve with spanner, the horn section of water inlet pipe can force resilient sleeve to expand, resilient sleeve after the expansion then is close to the inwall of the mouth of pipe, reaches the purpose of sealing.In the blast furnace cooling stave work pressure test, all install a device of the present utility model in each mouth of pipe additional, except that two mouths of pipe of water-in and water-out, connect with flexible pipe between other every.Water inlet place is joined with pressuring pump, and shutoff is carried out in water outlet place, and installs a tensimeter additional.When reaching test pressure, and after the voltage stabilizing time reached requirement, work pressure test just came to an end.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model synoptic diagram;
Embodiment
As shown in Figure 1: expansion pressure testing device in a kind of blast furnace cooling stave pipeline, it is installed on the pipeline opening 7 of blast furnace cooling stave pipeline, it comprises: a water inlet pipe 1, its end have external diameter and become big hydraucone gradually and connect cooling tube road junction 7 and be fixed on the pipeline opening 7 by a nut 3 and pad 4; A resilient sleeve 5, its internal diameter is complementary with the hydraucone of repeatedly kicking into water pipe 1 and is set on the hydraucone; A water supply hose 8, it is communicated with by a transfer tube 2 and water inlet pipe 1 the other end.The other end of described water inlet pipe 1 has outside screw, and described transfer tube 2 one ends are the internal thread hole that is connected with water inlet pipe 1, and the other end also has a rotating handles 6 for connecting the Link Port of water supply hose 8 on the body of described transfer tube 2.
Claims (3)
1. expansion pressure testing device in the blast furnace cooling stave pipeline, it is installed on the pipeline opening of blast furnace cooling stave pipeline, it is characterized in that, and it comprises:
