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 nonmetallic materials injection moulding to make, and be tank body and shell are connected as a single entity, be double-decker, or be separated with shell by tank body, water tank is injection molded into single layer structure; Water tank is made up of the first product 8-1 and the second product 8-2 two nonsymmetrical component; First product and the second product open at one end, the other end is closed, and on the end face of unlimited one end, has some attachment screw installing holes, and between and both ends of the surface binding site, installing seal 8-3, is double sealing structure; And the water flow sensing unit of band decompression is installed on the inlet pipeline of water tank; 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 nonmetal injection moulding water tank reduce 0.07-0.15Mpa, realizes, with nonmetal making water tank, to leak by crackle meanwhile, also can not exploding;
Accompanying drawing explanation
Fig. 1 to Fig. 3 is the water flow sensing unit structure chart of band decompression;
Fig. 4 to Fig. 6 is the electric heater schematic diagram of the water flow sensing unit that band decompression is housed;
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to embodiment be 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.
