Description
Technical field
The present invention relates to the metal water tank electric heater of the water flow sensing unit that band decompression is housed.
Background technology
Domestic, electric water heater all in the world at present, inlet pipeline is connected with water source, from water inlet to water tank, other assemblies are not installed, all can not pressure in self-regulating water tank, be all adopt pressure-bearing type structure, rated pressure is generally 0.6Mpa, and test pressure is 1.2Mpa; This pressure there will be many insoluble problems; The water tank that such as expands with heat and contract with cold can crackle, leak, pressure conference blast, be world-famous puzzle.
Summary of the invention
The present invention improves the electric heater that existing metal material makes water tank, for being equipped with the metal water tank electric heater of water flow sensing unit of band decompression after improvement, chewing 9 by shell 1, water inlet pipe 2, outlet pipe 3, the water flow sensing unit 4 with decompression, electrothermal tube 6, water tank 8, water, flange 11, relief valve 14 form.
The described water flow sensing unit 4 with decompression, by main body 4-1, cover plate 4-2, seal 4-3, spring 4-4, cover plate 4-5, sensing element 4-6, binding post 4-7, impeller or rotor or Hall element 4-8, piston 4-9 are installed, interface 4-10, water inlet 4-11 form.The described water flow sensing unit with decompression, is made up of two Functional portions A and B:
Part A, when having water flow, water jet propulsion impeller or rotor or Hall element 4-8 rotate, and by the induction to discharge, output pulse signal or the signal such as electric current, voltage, make auxiliary reclay adhesive, circuit turn-on, one or more groups electrothermal tube energising work; When closing water, water stops flowing, and circuit disconnects, and electrothermal tube stops heating;
Part B, piston 4-9 small end has a cross through hole, and also there is a through hole centre, during water inlet, water, by transverse holes, enters in water tank, during water inlet from piston 4-9 interstitial hole, not the entering of block water, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase, the large end of piston 4-9 produces back pressure, make piston displacement, turn down and even close water inlet 4-11; When discharging water, water inlet repeats to open; Thus can pressure in self-regulating water tank, this function guarantees that pressure in water tank is within 0.15mpa.
The described water flow sensing unit with decompression, A and B can discretely be two stand-alone assemblies, and part A should be contained in inlet pipeline, and part B is arranged on inlet and outlet pipe.
Described water tank adopts metal material to make, and comprises enamel cistern or stainless steel water tank, and on water tank water intake pipeline the water flow sensing unit 4 of mounting strap decompression, and in water tank, be equipped with corresponding relief valve.
Beneficial effect of the present invention and novelty are:
Water inlet tube of electric water heater road, is equipped with the water flow sensing unit 4 of band decompression, within making the pressure in metal water tank reduce 0.1-0.2Mpa by 0.6Mpa, can reduce water tank thickness, save material, can not leak by crackle meanwhile, also can not explode;
Accompanying drawing explanation
Fig. 1 to Fig. 3 is the water flow sensing unit structure chart of band decompression;
Fig. 4 to Fig. 8 is the electric heater schematic diagram of the water flow sensing unit that band decompression is housed;
Detailed description of the invention
Embodiment below in conjunction with accompanying drawing 1 to 8 is described, in accompanying drawing: shell 1, cold water inlet 2, hot water outlet pipe 3, water flow sensing unit 4 with decompression, controller 5, electrothermal tube 6 (upper electrothermal tube 6-1, lower electrothermal tube 6-2), sealing and fixing point 7, water tank 8, water chew 9, thermometric or limit temperature sensor mounting pipe 10, flange 11, relief valve 14.
Fig. 1 to Fig. 3 is the water flow sensing unit 4 with decompression, by main body 4-1, cover plate 4-2, seal 4-3, spring 4-4, cover plate 4-5, sensing element 4-6, binding post 4-7, impeller or rotor or Hall element 4-8, piston 4-9 are installed, interface 4-10, water inlet 4-11 form.The described water flow sensing unit with decompression, is made up of two Functional portions A and B:
Part A, when having water flow, water jet propulsion impeller or rotor or Hall element 4-8 rotate, and by the induction to discharge, output pulse signal or the signal such as electric current, voltage, make auxiliary reclay adhesive, circuit turn-on, one or more groups electrothermal tube energising work; When closing water, water stops flowing, and circuit disconnects, and electrothermal tube stops heating;
Part B, piston 4-9 small end has a cross through hole, and also there is a through hole centre, during water inlet, water, by transverse holes, enters in water tank, during water inlet from piston 4-9 interstitial hole, not the entering of block water, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase, the large end of piston 4-9 produces back pressure, make piston displacement, turn down and even close water inlet 4-11; When discharging water, water inlet repeats to open; Thus can pressure in self-regulating water tank, this function guarantees that pressure in water tank is within 0.15mpa.
Fig. 4 to Fig. 8 is the electric heater structural representation of the water flow sensing unit 4 that band decompression is housed; Water tank water intake, by the water flow sensing unit 4 of band decompression, no matter pipe-line system pressure size, can make water tank fill water fast, and make it be limited in setting range.
In accompanying drawing, water tank adopts enamel or uses stainless steel manufacture, and pressure is limited in 0.15Mpa, and this just thoroughly overcomes water tank makes water tank enamel split because expanding with heat and contract with cold, the problem of bead crack.
In accompanying drawing, electric heater has horizontal type structure, also has vertical structure, can be general, is that single water tank or many water tanks are all general.
In accompanying drawing, the water inlet pipe of water tank and outlet pipe are all the flexible nonmetallic tubings adopting length > 500mm, form physics water resistance, guarantee safety.
If by A and B of the water flow sensing unit 4 of band decompression, be divided into two parts, be arranged in water tank, also within this patent protection; Arrow is water (flow) direction.
