Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Shown in Fig. 1 and Fig. 2, according to embodiment of the present utility model, provide a kind of anti-freezing structure of water circuit system, the anti-freezing structure of the water circuit system of the present embodiment is used in the water circuit system of water heater especially, anti-freezing structure is arranged on the pipeline 40 of water circuit system, anti-freezing structure has the roof 21 for the outlet of shutoff pipeline 40, the outer surface of roof 21 is provided with the cannelure 23 forming stress and concentrate.
Cannelure defines stress at the outer surface of roof and concentrates, therefore Opposite top other place its to bear pressure little, when the unit of water heater is under low temperature environment for a long time, the pipeline inner pressure of water circuit system raises, when pipeline inner pressure exceedes force value (being generally 0.8 ~ 1MPa) that cannelure can bear, roof just annularly the section of groove split, discharge part is not freezed in water circuit system water, make the pressure of water circuit system inside remain on setting pressure.When after unit pressure release, only need to change the unit pipeline bursting by freezing that anti-freezing structure just can prevent water heater in time, after replacing, water heater just can be made normally to run, maintenance operation is convenient.
Anti-freezing structure comprises pipe joint 10 and capping 20, and the first end of pipe joint 10 is fixedly connected on pipeline 40, and pipe joint 10 has the through hole 11 be communicated with the pipeline 40 of water circuit system, and the water in pipeline 40 can enter into the through hole 11 of pipe joint 10.The sidewall 22 that capping 20 has roof 21 and is connected with roof 21, capping 20 is connected on pipe joint 10 by sidewall 22, roof 21 is positioned at the second end of pipe joint 10 and the second end of shutoff pipe joint 10, because the water of pipeline 40 can enter into through hole 11, so the second end of roof 21 shutoff pipe joint 10 is equal to the outlet of shutoff pipeline 40.See Fig. 2 and Fig. 3, the longitudinal section of the cannelure 23 in capping 20 is V-shaped, and cannelure 23 is positioned at the middle part of roof 21.
The roof 21 of the capping 20 of the present embodiment has the cannelure 23 of V-arrangement cross section, V-arrangement section produces stress because of shape sudden change and concentrates, so it is little that pressure bears compared with its elsewhere of capping 20 in place, when unit internal pressure exceedes the force value that V-arrangement cross section can bear, capping 20 is just ruptured at V-arrangement section, makes unit pressure release.
Conveniently keep in repair, the capping 20 in the present embodiment is connected on pipe joint 10.After capping 20 is ruptured, directly capping 20 is carried out replacing just passable, this also reduces the parts of replacing, reduce cost.
See Fig. 1 to Fig. 3, pipe joint 10 has the first boss 12 extended towards radial outside; Sidewall 22 is formed with away from the side of roof 21 the second boss 24, first boss 12 extended towards radial outside and abuts with the second boss 24, and the outward flange of the first boss 12 and the second boss 24 aligns.Abutted by the coupling of the first boss 12 and the second boss 24, facilitate capping 20 and pipe joint 10 to position installation.
Preferably, as shown in Figure 1, Figure 2 and Figure 4, anti-freezing structure also comprises the buckle 30 for realizing snap-fit engagement, and buckle 30 is connected on capping 20 and pipe joint 10, and capping 20 is connected on pipe joint 10 by buckle 30.When installing capping 20, by the cooperation of the first boss and the second boss, capping 20 being placed on the second end of pipe joint 10, then by buckle 30, capping 20 and pipe joint 10 being connected together.
See Fig. 2 and Fig. 4, in the present embodiment, buckle 30 comprises two holders 31 and connector 33, two holders 31 and is oppositely arranged and clamps the two ends that capping 20 and pipe joint 10, two holders 31 are connected to connector 33.Holder 31 is provided with the breach 32 for dodging placement first boss 12 and the second boss 24, and when two holders 31 clamp capping 20 and pipe joint 10, the first boss 12 and the second boss 24 are arranged in breach 32.
The free end of two holders 31 is formed with guide part 34, when clamping is carried out in buckle 30 pairs of cappings 20 and pipe joint 10, guide part 34 can lead to buckle 30, conveniently buckle 30 is inserted on the first boss 12 and the second boss 24, after completing clamping, first boss 12 and the second boss 24 are arranged in breach 32, and the first boss 12 and the second boss 24 are compressed laminating, to complete the clamping clamping to capping 20 and pipe joint 10 by the inwall of breach 32 by buckle 30.Distance between the free end of two holders 31 is identical with the width of connector 33, the clamping force that ensure that two holders 31 so effectively, and buckle 30 is firmly clamped in pipe joint 10 and capping 20.
It should be noted that, in other unshowned embodiments, capping can directly be connected on pipe joint, by arranging buckle respectively in capping and pipe joint and draw-in groove can realize.And the advantage being provided with separately buckle is, after avoiding capping fracture, can not be difficult to take off due to capping distortion, conveniently carry out maintain and replace.
The first end of the pipe joint 10 in the present embodiment is connected with pipeline 40 by screw thread or welding, the other end is connected with capping 20 by buckle 30, consider and need to carry out encapsulation process to water circuit system, so, in the present embodiment, sidewall 22 is set on the outer wall of pipe joint 10 second end, be provided with sealing ring 50 between the inwall of sidewall 22 and the outer wall of pipe joint 10 second end, as shown in Figure 1, the sealing ring 50 in the present embodiment is O-ring seals.
Certainly, be more than preferred embodiment of the present utility model.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model general principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
