Description
Technical field
The invention belongs to the pipeline connection technology field, relate to a kind of pipe fitting joint of solar energy heat collection pipe.
Background technique
Solar thermal collector is to be used for absorbing solar radiation to make it the device that converts heat energy into and pass to thermal medium.Existing solar thermal collector; All be the parallel connection type solar heat collector mostly, because the parallel connection of every solar energy heating components and parts all is a thermal-arrest under same initial temperature, thermal-arrest speed is slow; The thermal-arrest time is long; Day just can reach desired temperature half a day to one, can only be used to provide the washing of having a bath and live to use hot water, can not be applied to other field.
For this reason, people have invented a kind of serial solar energy water heater [notice of authorization number be: CN 2833437Y], and it comprises water tank, thermal-arrest plate, intake pipe, outlet pipe and drain valve, and a plurality of thermal-arrest plates adopt serial fashions to connect water tanks; Water tank bottom is provided with a return pipe, and return pipe connects intake pipe, and return pipe is provided with a water pump; During use, open the water source, cold water gets into the thermal-arrest plate through intake pipe; Solar irradiation heating is laggard goes into the water tank insulation, when using hot water, flows out through outlet pipe.
The thermal-arrest plate of this solar water heater links together through heat collecting pipe, and the end of heat collecting pipe offers outside thread, through the attaching nut end of two heat collecting pipes is connected during connection.Owing to offer screw thread in the end of heat collecting pipe, make it make difficult forming, even can't moulding; And the sealing of joint is relatively poor, through regular meeting leakage phenomenon takes place.
Summary of the invention
The objective of the invention is to have the problems referred to above to existing technology, proposed a kind of linkage structure firmly, good airproof performance, the pipe fitting joint that can effectively two pipe fittings be connected.
The object of the invention can be realized through following technical proposal:
This pipe fitting joint; Comprise the sleeve pipe that can be enclosed within on the pipe fitting; It is characterized in that described sleeve pipe middle part has and is used for being fixedly coupled portion with instrument, the two ends of sleeve pipe all are with sealed nut and sealed nut is connected with casing threads; Have the compressing structure that after casing threads is screwed, can compress pipe fitting when sealed nut between described sealed nut and the cannula tip, the described sealed nut outside has and is used for the rotation section that links to each other with instrument.
This pipe fitting joint is inserted into the two ends of sleeve pipe respectively with two pipe fittings when connecting, the sealed nut of screwing then makes compressing structure compress pipe fitting, prevents coming off of pipe fitting.In the process that spins, one of them sealed nut just changes, another sealed nut counter-rotating.The joint that is arranged on the sleeve pipe conveniently is fixedly connected with instrument, and instrument is fixed the joint of pipe fitting to this pipe fitting joint operation the time, through rotated portion, realizes sealed nut is screwed onto on the sleeve pipe.
In above-mentioned pipe fitting joint, described joint is prism-shaped.
Because joint is fixedly connected with instrument, when instrument in rotating process, must prevent that sleeve pipe from rotating with respect to instrument, so joint is arranged to prism-shaped, can realize the purpose of sleeve pipe and instrument axial restraint.
In above-mentioned pipe fitting joint, described joint is hexagonal prism structure.
In above-mentioned pipe fitting joint; Said sealed nut is inner to be connected with above-mentioned casing threads; Described compressing structure be sealed nut outer end to retaining edge of its inboard protrusion be used to be enclosed within the pressure ring on the pipe fitting, the two ends of pressure ring can contact with the retaining edge with cannula tip respectively.
In the process that sealed nut and sleeve pipe spin, sealed nut to the middle part of sleeve pipe near, pressure ring was under pressure and produced deformation this moment, and pipe fitting is locked.Since pipe fitting cannula tip and retaining along between, and sealed nut is connected with casing threads, after pipe fitting is locked by pressure ring, the characteristics that have difficult drop-off, are connected firmly.
In above-mentioned pipe fitting joint, described rotation section is the driven gear in the sealed nut outside.Be provided with like this and make things convenient for the operation of instrument sealed nut.
In above-mentioned pipe fitting joint, described sleeve port place has chamfering, and described sealed nut retaining has chamfering along the inner, and guide portion and guide portion that above-mentioned pressure ring two ends all have inclination can contact with above-mentioned chamfering.
The purpose that is provided with like this is, in the process of the sealed nut of precession, the power of this pressure ring converted sleeve pipe and sealed nut the impacting force of pressure ring to pipe fitting into, makes things convenient for pressure ring generation deformation, and pipe fitting is had better impacting force.
In above-mentioned pipe fitting joint, described sleeve pipe inboard has the position limiting convex ring of protrusion.
Position limiting convex ring mainly plays the role of positioning to the pipe fitting that is inserted in the sleeve pipe, and when connection was installed, the end that is inserted into the two pipe fittings in the sleeve pipe can be resisted against respectively on this position limiting convex ring, reaches the purpose of location.
In above-mentioned pipe fitting joint, described pressure ring adopts softer metals to process.
The purpose that is provided with like this is, makes things convenient for pressure ring to be under pressure back and generation deformation.
In above-mentioned pipe fitting joint, described pressure ring adopts aluminium material to process.
In above-mentioned pipe fitting joint, described pressure ring adopts brass material to process.
Compared with prior art, this pipe fitting joint has the following advantages:
Simple in structure and the operation of this pipe fitting joint and easily manufactured need not be provided with screw thread on joint, reduced the manufacture difficulty and the manufacture cost of pipe fitting.The pressure of pressure ring is converted sealed nut the impacting force of pressure ring to pipe fitting into, through the instrument sealed nut that spins, simple to operate, easy realization.Pressure ring adopts softer metals to process, and the deformation quantity of soft metal is big, and the impacting force of butt joint is just big more, connects back joint difficult drop-off, good stability.
