The specific embodiment
With reference to the accompanying drawings, be example with the storage-type electric water heater, the specific embodiment of the utility model is carried out detailed explanation.
As shown in Figure 1, electric heater comprises inner bag 1, and magnesium rod 2 and the magnesium rod seat 5 that is used for fixing magnesium rod 2 are installed in this inner bag 1; On inner bag 1, also be fixed with inlet tube and outlet tube stationary pipes 6; This inlet tube and outlet tube stationary pipes 6 is inserted with into water insulation tube 4, water outlet insulation tube 3 respectively in (being equivalent to the water pipe holder); Thereby inlet tube and outlet tube stationary pipes 6 is connected through screw thread with water inlet insulation tube 4 with water outlet insulation tube 3 respectively and realizes fixing water outlet insulation tube 3 and water inlet insulation tube 4; In water outlet insulation tube 3 and the junction of water inlet insulation tube 4 with inlet tube and outlet tube stationary pipes 6; O type circle 7 (being equivalent to sealing ring) also is installed, specifically as shown in Figures 2 and 3.
As shown in Figure 2, the water outlet insulation tube 3 of electric heater comprises water outlet bushing pipe 31, and this water outlet bushing pipe 31 is communicated with the inner chamber of inner bag 1 near the top (as shown in Figure 1) of inner bag 1.As shown in Figure 3, the water inlet insulation tube of electric heater 4 adopts the combining form of water inlet bushing pipes 41 and sleeve pipe 42, and the sleeve pipe 42 body portion cover dress of bushing pipe 41 in inner bag 1 of will intake can pass through bolt-nut (not shown) and fix in the end face junction of two water pipes.On the tube wall of water inlet bushing pipe 41 near the top, have through hole 43, the space between water inlet bushing pipe 41 and the sleeve pipe 42 is a water stream channel, and the sleeve pipe lower end is provided with several delivery ports 44 that communicates with inner bag 1.
As shown in Figures 2 and 3,, be formed with external screw thread 32 and 45 respectively, on water outlet insulation tube 3 and water inlet insulation tube 4, also be set with O type circle 7 in the periphery of metal insert 30,40 at water outlet insulation tube 3 and the chimeric respectively metal insert 30,40 that is fixed with of water inlet insulation tube 4.As shown in Figure 4, on inlet tube and outlet tube stationary pipes 6, be formed with internal thread 61, in addition, on the end face away from inner bag 1 housing of inlet tube and outlet tube stationary pipes 6, be formed with arc groove 8.When water outlet insulation tube 3 is installed with water inlet insulation tube 4; External screw thread 32,45 on the metal insert 30,40 screws with the internal thread 61 of inlet tube and outlet tube stationary pipes 6 respectively mutually; Connecting with the end face of the metal insert of the corresponding water outlet insulation tube 3 and the insulation tube 4 of intaking of inlet tube and outlet tube stationary pipes 6 from inner bag 1 outstanding jag end face; In addition, arc groove 8 is used to accommodate O type circle 7.
With the example that is connected to of water inlet insulation tube 4 and inlet tube and outlet tube stationary pipes 6, its sealing means is described.As shown in Figure 5, during installation, suit O type circle 7 on water inlet insulation tube 4 realizes that through external screw thread 45 and screwing of internal thread 61 water inlet insulation tube 4 is connected with inlet tube and outlet tube stationary pipes 6, and insulation tube 4 is fixed on the inner bag housing intaking.Because the syndeton on the metal insert 40 is an external screw thread 45, thereby can reduce the size of this metal insert 40, thereby has reduced manufacturing cost.In addition, O type circle 7 is pushed chimeric making in its formed space of end face that is clamped in arc groove 8 and metal insert 40.Compressional deformation through O type circle produces plays sealing function to the junction of water inlet insulation tube 4 and inlet tube and outlet tube stationary pipes 6.Adopt this sealing means, possess following two advantages:
(1) external screw thread 45 is set in water inlet on the insulation tube 4, internal thread 61 is set on inlet tube and outlet tube stationary pipes 6, during installation, can be in advance O type circle 7 be socketed in on the water insulation tube 4, thereby supporting construction be provided for O type circle 7.In addition, O type circle 7 is arranged in the formed space of end face of arc groove 8 and metal insert 40, and O type circle 7 is played the certain protection effect, avoids its long term exposure to cause breakage outside.
(2) cross section that is arranged on the groove on the inlet tube and outlet tube stationary pipes 6 is an arc, adopts this structure, on the one hand, and can be from the slip of the axially qualification O type circle 7 of inlet tube and outlet tube stationary pipes 6; On the other hand, can expand outwardly from the O type that radially the limits circle 7 of water inlet pipe and water outlet pipe 6, thereby strengthen sealing effectiveness.
O type circle 7 shown in Fig. 2-5 is circular ring type on the whole and is extruded in the formed space of end face that is entrenched in arc groove 8 and metal insert 40, and this O type circle 7 is an encapsulant, and general the employing has elastically-deformable elastomeric material, for example, and rubber, flexiplast etc.The global shape of its body shape and arc groove 8 is complementary, and is generally circle, certainly, because this O type circle 7 has elastic deformation, also can adopt other shapes.
Above-mentionedly only the sealing means of water inlet insulation tube 4 and inlet tube and outlet tube stationary pipes 6 is described,, does not do at this and give unnecessary details because water outlet insulation tube 3 is similar with it even identical with the sealing means of inlet tube and outlet tube stationary pipes 6.
The above is merely the preferred embodiment of the utility model, not in order to restriction the present invention.For example; In this embodiment, be example with the electric heater, also can adopt gas heater or solar water heater; Wherein structure such as the inner bag of described water heater, magnesium rod is prior art; The utility model focuses on: on water inlet insulation tube 3 and water outlet insulation tube 4, be formed with external screw thread respectively, in the through hole of water pipe holder, be formed with internal thread, making into through screwing of this external screw thread and internal thread, water insulation tube 3 is fixed on the water pipe holder with water outlet insulation tube 4.Adopt O type circle 7 (sealing rings) and 8 formation of arc groove sealing means to water outlet insulation tube 3, water inlet insulation tube 4 and inlet tube and outlet tube stationary pipes 6 junctions.In addition, described arc groove 8 is not limited to all be arranged on the inlet tube and outlet tube stationary pipes 6, also can partly or entirely be arranged on the water outlet insulation tube 3/ water inlet insulation tube 4.
In addition, in the above-mentioned explanation, by inlet tube and outlet tube stationary pipes 6 fixing water inlet insulation tubes 4 and water outlet insulation tube 3, yet also can adopt other fixed seat structures, to improve the intensity of the junction between holder and the inner bag 1.
In a word, all within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
