Abstract
The utility model relates to a water nozzle for a union collecting device of a solar water heating device and aims at providing the water nozzle for the union collecting device. The water nozzle for the union collecting device is simple in structure, low in cost, convenient to install, and capable of preventing a water nozzle connecting portion from water leakage and normal operation of the solar water heating device from being influenced. The water nozzle for the union collecting device comprises a water nozzle body. A ring-shaped protrusion is arranged on the outer circumferential face in the middle of the water nozzle body. As the ring-shaped protrusion is arranged on the outer circumferential face of the water nozzle, when the water nozzle installed in an installation hole of the union collecting device, a sealing ring is arranged on the water nozzle circumferential face at the right end of the ring-shaped protrusion to achieve sealing of the water nozzle and a union collecting device hole, a turning-up edge of a casing of the union collecting device at the installation hole is pressed to the water nozzle to enable the turning-up edge to abut against the right end face of the ring-shaped protrusion of the water nozzle to achieve fixation of the water nozzle. As the water nozzle is not welded to the union collecting device, and the sealing ring is arranged between the installation hole of the union collecting device and the water nozzle, the water nozzle for the union collecting device is capable of effectively preventing the water nozzle connecting portion from water leakage and enables the solar water heating device to work normally.
Description
Technical field
The utility model relates to the coupling device of solar water heater, particularly relates to a kind of water nozzle that is used for the solar water heater coupling device.
Background technology
In daily life; Solar water heater is widely used, and the water nozzle of prior solar water heater coupling device water tank all adopts welding manner to be connected on the coupling device, along with the variation of water temperature; Cracking often takes place and occurs leaking in its weld seam, influences the solar water heater operate as normal.
The utility model content
The technical problem that the utility model will solve provide a kind of simple in structure, cost is low, easy-to-install coupling device water nozzle, can avoid the water nozzle junction to leak and influence the solar water heater operate as normal.
The utility model coupling device water nozzle comprises the water nozzle body, and the outer circumference surface at water nozzle body middle part is provided with annular protrusion.
The utility model coupling device water nozzle, the cross section of wherein said annular protrusion are semicircle.
The utility model coupling device water nozzle, the left end of wherein said water nozzle body curves inwardly, and forms fillet.
The utility model coupling device water nozzle, the radius of wherein said fillet are 3 millimeters.
The utility model coupling device water nozzle difference from prior art is that the utility model is through being provided with annular protrusion on its outer circumference surface; In the time of in being installed in the installing hole of coupling device; On the water nozzle periphery of annular protrusion left end sealing ring is installed, is realized the sealing in water nozzle and coupling device hole, simultaneously the flange of installing hole place coupling device shell is pressed to water nozzle; The shell flange is withstood on the right side of annular protrusion of water nozzle, realize that water nozzle fixes.Because water nozzle is not welded on the coupling device, and between coupling device installing hole and water nozzle, sealing ring is set, and can effectively avoid water nozzle junction flowing water, makes the solar water heater operate as normal.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 looks cutaway view for the master of the utility model coupling device water nozzle;
The master that Fig. 2 is installed in the coupling device for the utility model coupling device water nozzle looks cutaway view.
The specific embodiment
As shown in Figure 1, a kind of coupling device water nozzle comprises water nozzle body 1, and the outer circumference surface at water nozzle body 1 middle part is provided with annular protrusion 2, and the cross section of annular protrusion 2 is semicircle.The left end of water nozzle body 1 curves inwardly, and forms fillet 3, and the radius of fillet 3 is 3 millimeters.
When this device is installed, as shown in Figure 2, at first two rubber seal 4 are enclosed within the left end of water nozzle; Because the left end of water nozzle is provided with fillet 3, can avoid scratching rubber seal 4, then water nozzle is packed in the installing hole 6 of coupling device 5 from right to left; Coupling device 5 mainly is made up of metal shell 7, heat-insulation layer 8 and inner bag 9, and the position that installing hole 6 is positioned at heat-insulation layer 8 is a stepped hole, and the left end of sealing ring 4 is pressed on the step of stepped hole; The right-hand member of sealing ring 4 is pressed on the annular protrusion 2, realizes sealing, and is last; With flange 10 pressings of installing hole 6 place's shells 7, flange 10 is pressed on the right side of annular protrusion 2 of water nozzle, realize the fixing of water nozzle.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
Claims (4)
