Abstract

The utility model relates to a sealing connector which is used to connect flexible pipes. The sealing connector is characterized in that the sealing connector which is used to connect the flexible pipes comprises a connector screw cap (1) and a flexible pipe connecting main body (2), one end of the flexible pipe connecting main body (2) is provided with an inner screw thread which is connected with a rigid pipe, the other end is provided with an outer screw thread which is connected with the connector screw cap (1), the connector screw cap (1) is provided with the inner screw thread, when the connector screw cap (1) and the flexible pipe connecting main body (2) are installed through tightly screwing, and a gap between the connector screw cap (1) and the flexible pipe connecting main body (2) can clamp one end of the flexible pipe (3) which will be connected. The structure is simple, the installment is convenient, and the connecting inconvenience of a flange mode, an adhering mode and a welding mode is avoided. When corrosion-resisting plastic materials are adopted, liquid with strong corrosiveness such as materials with corrosive acid, strong base and strong oxidizing property can be resisted, and simultaneously the sealing connector in particular resists the electrochemical corrosion. The problem of expanding on heating and contracting on cooling when a non-metallic pipeline is rigidly connected is overcome.

Description

A kind of SEALING FITTING that is used to connect flexible pipe
Technical field
The utility model relates to mechanical field, and a kind of SEALING FITTING that is used to connect flexible pipe is provided especially.
Background technique
In liquid line, the Placement that is usually used between hard tubes such as metal and plastics mainly comprises: three kinds of rigid Placements such as flange-type, adhered and welding type.Then employing that be connected between hard tube and flexible pipe tightly pricked flexible pipe the metal pipe collar on hard tube more, and the mechanical reducing by pipe collar makes flexible pipe be out of shape sealing with realization flexible pipe and hard tube.Plastic pipe is usually used in Korrosionsmedium, as strong acid, highly basic or strong oxidizing property material etc.If adopt this moment the metal pipe collar to connect flexible pipe and hard tube, the corrosive gas in the environment or the evaporating, emitting, dripping or leaking of liquid or gas of pipeline easily cause the corrosion of pipe collar, therefore have potential safety hazard.
The model utility content
The purpose of this utility model has provided a kind of SEALING FITTING that is used to connect flexible pipe that prevents the pipe collar corrosion.
A kind of SEALING FITTING that is used to connect flexible pipe, it is characterized in that: the described SEALING FITTING that is used to connect flexible pipe comprises that collar nut (1) is connected main body (2) with flexible pipe, flexible pipe connects main body (2) one ends and has the internal thread that is connected with hard tube, the other end has the outside thread that is connected with collar nut (1), collar nut (1) has internal thread, collar nut (1) is connected main body (2) and screws when installing with flexible pipe, between the slit can clamp an end of the flexible pipe (3) that will connect.
It is cylindrical tube that described flexible pipe connects main body (2).
The end that described flexible pipe connects main body (2) has circular protrusion, and this circular protrusion and cylinder type pipe fitting are one, and its slightly larger in diameter is in the internal diameter of the flexible pipe that will connect (3).
Described flexible pipe connect in the main body (2) externally threaded in the difference of footpath and the external diameter of circular protrusion less than the thickness of the flexible pipe that will be connected (3) tube wall.
When being used to connect flexible pipe, at first hose proof is connected on the hose coupling part of main body at flexible pipe, then collar nut (1) is tightened to gradually on the outside thread of hose coupling part.Because the outside thread of hose coupling part and the thickness of the diameter difference of circular protrusion less than the flexible pipe tube wall, in the process of tightening gradually, flexible pipe (3) closely contacts with circular protrusion on the hose coupling, and formation seals.
Advantage of the present utility model:
Simple in structure, easy for installation, avoided the connection inconvenience of traditional flange-type, adhered and welding type.When adopting the corrosion-resistant plastic material, being able to bear strong corrosion property liquid as strong acid, highly basic, strong oxidizing property material, also tolerates electrochemical corrosion simultaneously especially.The problem of having expanded with heat and contract with cold when having overcome the rigid connection of nonmetal pipeline.
Description of drawings
Below in conjunction with drawings and the embodiments the utility model is described in further detail:
Fig. 1 connects the main body sectional view for flexible pipe;
Fig. 2 is collar nut figure;
Fig. 3 connects main structure chart for flexible pipe;
Fig. 4 is the SEALING FITTING erection drawing.
Embodiment
Embodiment 1
Present embodiment is introduced a kind of SEALING FITTING that is used to connect flexible pipe φ 26 * 3, critical piece is that collar nut (1) is connected main body (2) with flexible pipe, flexible pipe connects main body (2) one ends and has internal thread M18 * 2 that are connected with hard tube, the other end has outside thread M25 * 1.5 that are connected with collar nut (1), and collar nut (1) has internal thread M25 * 1.5.The end that flexible pipe connects main body (2) has formed circular protrusion and the cylinder type pipe fitting is an one from φ 21 gradual change φ 23.When being used to connect flexible pipe, at first hose proof is connected on the hose coupling part of main body at flexible pipe, then collar nut (1) is tightened to gradually on outside thread M25 * 1.5 of hose coupling part.Because the outside thread of hose coupling part and the thickness of the diameter difference of circular protrusion less than the flexible pipe tube wall, in the process of tightening gradually, flexible pipe (3) closely contacts with circular protrusion on the hose coupling, and formation seals.
Embodiment 2
Present embodiment is introduced a kind of SEALING FITTING that is used to connect flexible pipe φ 42 * 5, critical piece is that collar nut (1) is connected main body (2) with flexible pipe, flexible pipe connects main body (2) one ends and has and be used for the pipe fitting socket joint gluing with hard tube φ 40, the other end has outside thread M47 * 2 that are connected with collar nut (1), and collar nut (1) has internal thread M47 * 2.The end that flexible pipe connects main body (2) has formed circular protrusion and the cylinder type pipe fitting is an one from φ 31 gradual change φ 36.When being used to connect flexible pipe, at first hose proof is connected on the hose coupling part of main body at flexible pipe, then collar nut (1) is tightened to gradually on outside thread M47 * 2 of hose coupling part.Because the outside thread of hose coupling part and the thickness of the diameter difference of circular protrusion less than the flexible pipe tube wall, in the process of tightening gradually, flexible pipe (3) closely contacts with circular protrusion on the hose coupling, and formation seals.
