Abstract
The utility model discloses a plumbery piece, in particular a telescopic supplemental core which comprises a supplemental core body (1), a sealing press cap (2) arranged on the joint of the right side supplemental core (7), a rubber sealing ring (3) in the sealing press capand a gasket (4). The utility model is multifunctional and no screw thread is needed on the pipes which are connected with the telescopic supplemental core; when the pipeline is heated, the utility model has flexibility and is not easy to leak, therefore, the installation and maintenance is especially convenient and lots of pipe fittings are saved.
Description
The utility model relates to a kind of hot-water heating spare, particularly a kind of flexible bushing.
At the common used hot-water heating spare in the north of China, an end is installed on the heating installation when using as bushing at present, and the other end has screw thread, and be connected with the heating installation pipe, its shortcoming of this bushing is when the pipeline expanded by heating, does not have stretchability, is easy to leak, near the convenience in order to keep in repair on the pipeline of bushing, a loose joint also need be installed usually, so just bring many troubles, waste a large amount of steel to installation, joint was many more when pipeline was installed, and breakthrough is many more; Our usually used loose joint in addition is the dock structure and since pipe when installing deviation bigger, decentraction so very trouble is installed, is easy to seepage, maintenance difficulty, so just be badly in need of a kind of hot-water heating spare replace bushing, in connect, loose joint, pipeline extension device use one more.
The purpose of this utility model is to provide a kind of, and it is convenient that maintenance is installed, easy to leak not, flexible bushing simple in structure.
The purpose of this utility model is to realize like this, this bushing is made up of bushing main body, seal pressure cap, rubber seal, four main parts of pad, the right side of hexagonal boss has and is processed with externally threaded bushing joint on its bushing main body, and bushing joint inside has platform and connects the shape hole; Its rubber seal center has through hole, and the right side has boss; Its seal pressure cap is a hexagon, and the center, left side has a macropore, and inside is processed with internal thread, and in order to join with the bushing joint, the center, right side has an aperture.Will the bushing main body during installation left side join with radiator, the pipe that the right side will be with rubber seal and pad is packed in the bushing joint, then seal pressure cap is enclosed within on seal ring and the pad, is screwed on the bushing joint and can finishes purpose of the present invention.
The utility model is owing to adopted above-mentioned mounting structure, the pipeline that is connected with this bushing does not need threading, thereby just can replace bushing in the past with a novel bushing part, in connect and loose joint, because the tube end that pipeline links to each other with bushing when installing is not fixed, institute's heart has stretchability, not easy to leak when the heating installation temperature distortion, installation and maintenance are convenient, save material.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1, be flexible bushing perspective view;
Fig. 2, use the installment state cut-away view for flexible bushing;
Fig. 3, partly use the installment state cut-away view for loose joint.
Describe concrete structure of the present utility model and use condition in detail below in conjunction with accompanying drawing.
The utility model is made up of bushing main body 1, seal pressure cap 2, rubber seal 3,4 four main parts of pad, and the right side of hexagonal boss has and is processed with externally threaded bushing joint 7 on its bushing main body, and bushing joint 7 inside have platform and connect the shape hole; Its rubber seal 3 centers have through hole, and the right side has boss; Its seal pressure cap 2 is a hexagon, and the center, left side has a macropore, and inside is processed with internal thread, and in order to join with bushing joint 7, the center, right side has an aperture.During installation bushing main body 1 left side and radiator are joined, the pipe 5 that the right side will be with rubber seal 3 and pad 4 is packed in the bushing joint 7, then seal pressure cap 2 is enclosed within on seal ring 3 and the pad 4, is screwed on the bushing joint 7 and can finishes purpose of the present invention.
Embodiment 1, as Fig. 2, the left end and the radiator of bushing main body 1 join, the end that rubber seal 3, pad 4 are enclosed within pipe 5 is contained in bushing joint 7 places on the bushing main body 1, and its seal pressure cap 2 of screwing on is got final product.
Embodiment 2, and as Fig. 3, this structure also can be applicable to loose joint, bushing main body 1 is become loose joint main body 6, the close circle 3 of rubber, pad 4 are enclosed within an end of pipe 5, it is installed in the joint on loose joint main body 6 right sides, the seal pressure cap 2 of screwing on gets final product, and this kind loose joint installs convenient especially.
Claims (2)
1, a kind of flexible bushing is characterized in that, this bushing comprises bushing main body (1), be installed in seal pressure cap (2) on the right side bushing joint (7), and seal pressure cap in rubber seal (3), pad (4).
2, a kind of flexible bushing according to claim 1 is characterized in that:
The right side that a, bushing main body (1) go up hexagonal boss has and is processed with externally threaded bushing joint (7), and bushing joint (7) inside has platform and connects the shape hole;
B, seal pressure cap (2) are hexagon, and the center, left side has a macropore, and inside is processed with internal thread, and the center, right side has an aperture;
C, rubber seal (3) center have through hole, and the right side has boss.
