Abstract

The utility model relates to a connector which is used for connecting a pipe with one smooth end and a pipe with threads on the other end. The connector is especially suitable for solar water heaters and belongs to the field of hardware fittings. The connector is a hollow pipe, and the inner wall of one end of the hollow pipe is provided with internal threads which are directly connected with a common galvanized pipe; the outer wall of the other end is provided with external threads. A pipe of a solar energy heat collection board is inserted into a spiral ring which is twisted tightly and matched with the external threads. The utility model has the advantages of simple structure, convenient installation and use, good seal and connection performances, long service life, no maintenance and beautiful appearance, and is a novel connector for connecting smooth pipe walls and pipe walls with threads.

Description

The coupling that connects smooth tube wall and screw thread tube wall

The utility model be a kind of be an end that smooth tube, the other end are the coupling that threaded pipeline links together, be particularly suitable for solar water heater and use, belong to the hardware fitting field.

When solar water heater is installed, solar heat-collection plate need be connected with the pipeline of water storage box, because of the pipe wall of plate type solar heat collection plate all is to use aluminium, metallic material such as copper pipe or Stainless Steel Tube is made, its tube wall is thinner, all impossible tapping inside and outside the tube wall, and the pipeline in the hot water storage tank is common water pipe, its tube wall has all been attacked screw thread, so can't they be interconnected with the ordinary water joint for pipe between the two, people have to use a rubber pipe that diameter is suitable, on two tube walls of socket, tightening with iron wire or larynx hoop more respectively, is smooth tube with an end, the other end is that threaded pipeline connects.Though this Placement is simple, its outward appearance is ugly, rubber pipe year in and year out, aging embrittlement is easy to generate and leaks.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, solve people's open question for many years, invent an a kind of end termination and have internal thread, the other end termination has externally threaded volution, and the coupling that is connected smooth tube wall and screw thread tube wall of bung flange that be used with volution, that have internal thread.

The purpose of this utility model be to invent a kind of be specially adapted to connect pipeline between the solar heat-collection plate, by the bung flange with internal thread with have the common coupling that is connected smooth tube wall and screw thread tube wall that form, better tightness of externally threaded volution and swivel nut.

The purpose of this utility model is finished like this: the coupling that connects smooth tube wall and screw thread tube wall, it is characterized in that coupling is a hollow tubular, one end termination inwall has internal thread, the other end termination outer wall has outside thread, reach bung flange with the outside thread coupling, bung flange is concavity, has a through hole in the middle of it, and screw thread is arranged on the madial wall; Between the outside thread (12) and bung flange of coupling one end termination, swivel nut can be housed, a breach is arranged on the swivel nut collar, breach two preferably respectively is 45; Angle β between two terminations of coupling is 60-180 ° of scope, and the two ends outer wall of coupling preferably is the hexagonal shape.

During use, the end termination that coupling (1) is had an internal thread (11) directly with hot water storage tank on common galvanizing pipe get final product by being threaded, the smooth tube of thermal-arrest plate is inserted in the other end termination, loads onto swivel nut (3) and bung flange (2), tightens bung flange (2) and then can.The utility model coupling (1) can be made into through-type (then the angle β between two terminations of coupling is 180 °), also can be made into elbow (then the angle β between two terminations of coupling is 90 °): the available metal material, also can make, as long as can mate mutually between both internal diameters and external diameter and screw thread and the thread of nonmetallic material.Swivel nut (3) is preferably selected for use has the making of necessarily flexible (non-) metallic material, to guarantee sealing.

The utility model coupling has simple in structure, and installation, easy to use connects good seal performance, long service life, and non-maintaining, the advantage of beautiful shape is a kind of novel smooth tube wall of connection and the coupling of screw thread tube wall.

Be described further below in conjunction with accompanying drawing illustrated embodiment structure, but protection domain is not limited to embodiment.

When Fig. 1 is 90 ° for angle β between two terminations of coupling (embodiment), coupling is installed in the user mode schematic representation in the solar water heater.

Fig. 2 is coupling embodiment's shown in Figure 1 sectional view (not comprising swivel nut and bung flange).

Fig. 3 is the plan view of bung flange parts

Fig. 4 is the sectional view of bung flange parts shown in Figure 3.

Fig. 5 is the plan view of turnbuckle parts

Fig. 6 is the sectional view of turnbuckle parts shown in Figure 5.

Fig. 7 is coupling embodiment's shown in Figure 10 sectional view (not comprising swivel nut and bung flange).

Fig. 8 is the A-A direction sectional view of coupling shown in Figure 7.

Fig. 9 is the local cut-away view that amplifies of coupling shown in Figure 1.

When Figure 10 is 180 ° for angle β between two terminations of coupling (another embodiment), coupling is installed in the user mode schematic representation in the solar water heater.

Press Fig. 1 and structure shown in Figure 3, select for use cast iron to make coupling (1), the aperture of one end termination and the pipeline of solar heat-collection plate coupling, its outer wall has outside thread (12); There is internal thread (11) the other end termination, and the thread of its screw thread and common galvanized pipe is complementary.The two ends outer wall of coupling (1) is the hexagonal shape, is convenient to install.Swivel nut (3) selects for use cast iron to make, and breach (31) oblique angle is 45 degree.Bung flange (2) selects for use cast iron to make, the pipeline coupling of through hole (22) size and solar heat-collection plate, and inwall has internal thread (21); During use, with coupling (1) one end directly with common galvanizing pipe (4) by being threaded; Pipeline in thermal-arrest plate (5) puts bung flange (2) and swivel nut (3), the pipeline in the thermal-arrest plate (5) is inserted in another stomidium of coupling (1) again, tightens bung flange (2).Because swivel nut (3) has certain elasticity, so good airproof performance, the profile of whole solar water heater seems more elegant in appearance.
