Embodiment
Embodiment one
The present embodiment adopts the heat pump water heater of tank seal assembly as shown in Figure 1, the water tank 1(be made up of cylindrical shell 1-2, top cover 1-1 and bottom 1-3 is installed in shell 2 and is commonly called as inner bag), the vertical plug-in mounting of spiral heat exchange coil pipe 3, top cover 1-1 is settled to be used for the anode bar 4 of corrosion protection in this water tank 1.The two ends of coil pipe 3 are passed from the tank seal assembly 5 being arranged in cylindrical shell 1-2 by connecting tube 3-1 respectively, external heat pump circulating system (because analysing and observe in figure, illustrate only a place).
The concrete structure of tank seal assembly 5 as shown in Figure 2, base 5-1 and water tank cylindrical shell 1-2 is all stainless steel, one end of proximity thermal water heater tank cylindrical shell 1-2 is shaped with border V-shaped groove 5-1a, and full weld is fixed on outside the perforation of cylindrical shell 1-2, therefore can form solid and reliable welded seal structure.Perforation has ring-type in-flanges 1-2a, and base 5-1 has the interior threaded hole that latus rectum is greater than penetration hole diameter.Load in base 5-1 and have the sealing plug 5-3 of center through hole, sealing plug 5-3 has small end outer cone outwardly and is extended into the lining ring 5-3a of perforation by through hole, and forms cylinder table stage 5-1b in the inner of outer cone.In through hole, plug-in mounting stretches into copper heat exchange medium pipe (also known as the refrigerant pipe) 3-1 of water-heater water tank cylindrical shell 1-2.Screw in the interior threaded hole of base 5-1 there is the inner cone that to match with sealing plug 5-3 outer cone hollow plug screw 5-4(also known as horn mouth base), the cylindrical pressure holding of its inner, on the annular end face of cylinder table stage 5-1b, plays the effect that powerful pressure holding strengthens sealing.The outer end of base 5-1 has the sunken end face of embedded sealing ring 5-6, and the outer end of hollow plug screw 5-4 has the radial extension edge 5-4a of pressure holding seal ring 5-6, therefore forms two seals and axial vibration insulation structure with cylinder table stage 5-1b.The interior outer end of hole of hollow plug screw 5-4 forms the little horn mouth 5-4b of outer imperial palace, is convenient to plug-in mounting and the turning of connecting tube 3-1.
Because the heat exchange circulation pipeline of heat pump water heater has vibration, therefore the sealing plug reality of the present embodiment also plays a part the vibration of heat exchange medium pipe and water tank cylindrical shell to isolate.And when vibration isolation, vibration displacement compresses the sealing surface positive pressure produced change screwing hollow plug screw under making original state of rest, as improper in pretension, the sealing surface likely causing pretension positive pressure less produces interim leakage.Consider that vibration displacement direction has certain randomness, when therefore wishing each sealing surface pretension, be in the state that positive pressure is basically identical, thus have each to the substantially identical compensation ability overcoming interim leakage.
Theory analysis and experimental research show, (see Fig. 3, place shown in thick line is limited sealing surface) when the sealing plug external taper slope tan θ of Fig. 3 equals radial effective sealing area and axial effective sealing area ratio, the unit area positive pressure in circumference and shaft end seal face can be made basically identical, thus have each to the substantially identical compensation ability overcoming interim leakage.
Radial effective sealing area is determined by the area of contact of sealing plug interior edge face and water tank cylindrical shell appearance, namely equals (D in Fig. 3
2-D1
2) π/4; Axial effective sealing area is determined to the through hole section of interior edge face and pipe cylindrical area of contact from small end by sealing plug, namely equals π dL.
Like this, when tightening hollow plug screw, male cone (strobilus masculinus) by sealing plug is produced radial component F1 and axial thrust load F2, thus form sealing plug endoporus with between pipe outer round surface and unit area positive pressure substantially identical between sealing plug interior edge face and water tank barrel outer surface and decrement, ensure reliable radial and axial sealing under vibrational state simultaneously; And because stainless steel water tank and base and plug screw and copper coin pipe separate completely, therefore while stopping electrochemical corrosion, also by the vibration of pipe and water tank completely isolated, play desirable anti-vibration effect.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
