Abstract
The utility model discloses a solar vacuum tube which comprises a vacuum tube body. A sealing cover is installed at an opening end of the vacuum tube body. A water inlet copper tube and a water outlet copper tube are installed on the sealing cover, the bottom end of a screw rod is installed on the sealing cover, the head end of the screw rod is provided with a nut, the nut is embedded in a rubber plug, and a sealing ring is installed between the rubber plug and the sealing cover. The solar vacuum tube is used for a solar water heater, can achieve effective cost reduction by means of a simple device, reduces machining difficulty, and is good in sealing performance.
Description
Technical field
The utility model relates to a kind of solar energy heat absorption pipe, relates in particular to a kind of solar energy vacuum tube.
Background technology
At present, comparatively loaded down with trivial details at method for blocking and device that the head end of existing solar energy vacuum tube adopts, and head end processing request and the production cost of vacuum tube is very high now, has caused very large waste, processing that must specialty, the cost high efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of good airproof performance, can save the solar energy vacuum tube of cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of solar energy vacuum tube, comprise vacuum tube, the mouth end of vacuum tube is installed seal cover, water inlet copper pipe and water outlet copper pipe are installed on the seal cover, it is characterized in that: the bottom of screw rod is installed on the seal cover, the head end mounting nuts of screw rod, nut is embedded in the rubber stopper, between rubber stopper and the seal cover sealing ring is installed.
The utility model has the advantages of and be: can utilize simple device to realize effective reduction of cost, reduced the difficulty of processing, and sealing be better.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: 1, water inlet copper pipe; 2, screw rod; 3, nut; 4, pad; 5, sealing ring; 6, rubber stopper; 7, vacuum tube; 8, seal cover; 9, water outlet copper pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of solar energy vacuum tube, comprise vacuum tube 7, the mouth end of vacuum tube 7 is installed seal cover 8, water inlet copper pipe 1 and water outlet copper pipe 9 are installed on the seal cover 8, and it is characterized in that: the bottom of screw rod 2 is installed on the seal cover 8, the head end mounting nuts 3 of screw rod 2, nut 3 is embedded in the rubber stopper 6, and sealing ring 5 is installed between rubber stopper 6 and the seal cover 8.
Use principle of the present utility model as shown in Figure 1, water enters into vacuum tube 7 from water inlet copper pipe 1, flow out from water outlet copper pipe 9 after taking away heat, because nut 3 is embedded in the rubber stopper 6, so when tightening screw rod 2, rubber stopper 6 will be compacted, thereby reach the effect of sealing, and sealing ring 5 can increase the effect of sealing.
The utility model can utilize simple device to realize effective reduction of cost, reduced the difficulty of processing, and sealing is better.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model.
