Abstract
The utility model relates to an elastic tube clamp for a solar vacuum tube. The elastic tube clamp for the solar vacuum tube comprises a tube clamp body which is mounted between an outer tube and an inner tube of the solar vacuum tube and is arranged on the outer wall of the inner tube in a sleeved mode. The tube clamp body comprises at least three sections of inner tube brackets, arc-shaped clamps matched with the outer wall of the inner tube are arranged on the inner tube brackets, and an outer tube supporting bracket which protrudes outwards is arranged between every two adjacent inner tube brackets. Each outer tube supporting bracket comprises an arc-shaped elastic supporting ring matched with the inner wall of the outer tube, and the two ends of each arc-shaped elastic supporting ring are connected with the ends of the adjacent inner tube brackets through elastic compensation connecting straps respectively. According to the elastic tube clamp, deformation can be achieved through the arc-shaped elastic supporting rings and the elastic compensation connecting straps, the radial elastic deformation amount is large, mounting is convenient, so that the tube clamp is fixed between the inner tube and the outer tube to enable the inner tube to be fixed inside the outer tube, the diameter of each arc-shaped elastic supporting ring is far smaller than the diameter of the outer tube, hence, the contact area of the arc-shaped elastic supporting rings and the inner wall of the outer tube is small, and heat conduction loss is lowered.
Description
Technical field
The utility model relates to a kind of pipe clamp, particularly a kind of elasticity pipe clamp for solar vacuum heat-collecting pipe.
Background technology
When solar vacuum heat-collecting pipe inner and outer pipes seals, concentric for guaranteeing inner and outer pipes, generally can fill at the mouth of pipe place locating ring, structure as shown in Figure 1,1 ' be inner glass tube, 2 ' be outer glass pipe, 3 ' be round end Spring Card, 4 ' be locating ring, 5 ' be evaporable air-absorbing agent.At present, several having of use, as shown in Figure 2, helical form locating ring 4a.As shown in Figure 3, wavy locating ring 4b.As shown in Figure 4, " U " type locating ring 4c.
Several locating rings above, elastic deformation amount is radially less, installs and uses inconvenience, large with inner and outer pipes contact area, has increased heat waste, and processing technology is relatively loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, and radial elastic deflection is large, the elasticity pipe clamp for solar vacuum heat-collecting pipe easy for installation.
Technical problem to be solved in the utility model is to realize by following technical scheme, a kind of elasticity pipe clamp for solar vacuum heat-collecting pipe, be characterized in: comprise and be arranged between solar vacuum heat-collecting pipe outer tube and inner tube and be sleeved on the pipe clamp body on outer wall of inner tube, described pipe clamp body comprises suit at least 3 sections of inner tube conduit saddles on inner pipe, inner tube conduit saddle is provided with the arc card coordinating with outer wall of inner tube, between adjacent two inner tube conduit saddles, be provided with cambered outwards outer tube supporting bracket, outer tube supporting bracket comprises the arc elastic support ring coordinating with outer tube wall, the two ends of arc elastic support ring are connected with the end of adjacent inner tube conduit saddle by elastic compensating brace respectively.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the described elasticity pipe clamp for solar vacuum heat-collecting pipe, is characterized in: described pipe clamp body is made by sheet or thread stainless steel material.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the described elasticity pipe clamp for solar vacuum heat-collecting pipe, is characterized in: an inner tube conduit saddle is provided with opening therein.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the described elasticity pipe clamp for solar vacuum heat-collecting pipe, is characterized in: the middle part of every section of arc elastic support ring is equipped with the salient point mutually tactile with solar vacuum heat-collecting pipe outer tube wall.
Elastic tube cartoon of the present utility model crosses arc elastic support ring and elastic compensating brace is realized distortion, thereby it is fixing within the outer tube by inner tube that pipe clamp is fixed between inner tube and outer tube, and the diameter of arc elastic support ring is much smaller than outer tube diameter, therefore the contact area of arc elastic support ring and outer tube wall is little, thereby has reduced the conduction loss of heat, compared with prior art, it is simple in structure, be easy to processing and store, radial elastic deflection is large, easy for installation.

The specific embodiment
With reference to figure 5 and Fig. 7, a kind of elasticity pipe clamp for solar vacuum heat-collecting pipe, comprise and be arranged between solar vacuum heat-collecting pipe outer tube 6 and inner tube 5 and be sleeved on the pipe clamp body without film zone position near inner tube 5 outer walls of the mouth of pipe, that described pipe clamp body adopts is high temperature resistant, the good sheet of elasticity or thread stainless steel material crimping are made.
Described pipe clamp body comprises at least 3 sections of inner tube conduit saddles 1 that are sleeved in inner tube 5, and inner tube conduit saddle 1 is provided with the arc card coordinating with inner tube 5 outer walls, and the slightly larger in diameter of inner tube conduit saddle 1 is in inner tube 5 overall diameters.Between adjacent two inner tube conduit saddles 1, be provided with cambered outwards outer tube supporting bracket, the circumcircle of outer tube supporting bracket is slightly larger than outer tube 6 internal diameters.Outer tube supporting bracket comprises the arc elastic support ring 3 coordinating with outer tube 6 inwalls, and the two ends of arc elastic support ring 3 are connected with the end of adjacent inner tube conduit saddle 1 by elastic compensating brace 2 respectively.The diameter of each arc elastic support ring 3 is much smaller than outer tube 6 internal diameters.During installation, when inner tube conduit saddle 1 is sleeved in inner tube 5, under the elastic deformation pressure of arc elastic support ring 3 and elastic compensating brace 2, the middle part of arc elastic support ring 3 tightly withstands on the inwall of outer tube 6, thereby inner tube 5 is positioned in outer tube 6.
An inner tube conduit saddle 1 is provided with opening therein, can solve like this problem of the assembling difficulty causing because of caliber deviation.The middle part of every section of arc elastic support ring 3 is equipped with the salient point 4 mutually tactile with solar vacuum heat-collecting pipe outer tube 6 inwalls, as shown in Figure 6, by this salient point 4, arc elastic support ring 3 is tightly withstood on the inwall of outer tube 6, thereby minimizing contact area, between elasticity pipe clamp and outer tube 6, to contact, reduced greatly heat loss.
