The described water flow switch 4 with decompression, being made up of A, B bis-functional parts, is multifunctional module:
Part A, in main body 4-1, the passage of water inlet and water outlet is not directly communicate, but separated by cover plate 4-2, when there being water flow, water can be forced promotion cover plate 4-2, simultaneously promotion seal 4-3 with impeller 4-4 and movable contact 4-9 contacted with stationary contact 4-8 or microswitch 4-7 is connected, circuit turn-on: when current are closed, water inlet is closed, and circuit also disconnects.
Part B, piston 4-12 small end has a cross through hole, and centre is also porose, during water inlet, water, by transverse holes, enters in water tank from piston 4-12 interstitial hole, during water inlet, not the entering, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase of block water, piston 4-12, large end produces back pressure, and piston 4-12 is subjected to displacement, and turns down and even closes water inlet 4-14; 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.
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, respectively installing seal 8-3, is double sealing structure; And the water flow switch 4 installed on water tank water intake pipeline with decompression, in water tank, be equipped with corresponding relief valve.
Beneficial effect of the present invention and novelty are:
1. water inlet tube of electric water heater road, is equipped with the water flow switch 4 of band decompression, within making the rated pressure in nonmetal injection moulding water tank reduce 0.1-0.2Mpa, realizes making water tank by nonmetallic materials Shooting Technique, can not leak by crackle meanwhile, also can not explode.
2. the water inlet of water tank and outlet pipe all adopt the flexible nonmetallic tubing of length > 500mm, with nonmetal water tank, jointly form physics water resistance, are perfectly safe.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 4, Fig. 5 are the Water flow switch structure figure of band decompression;
Fig. 3 is microswitch schematic diagram;
Fig. 6 to Fig. 8 is the nonmetal injection moulding water-tank electric water heater schematic diagram of the water flow switch 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 switch 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 nozzle 9, thermometric or temperature limit switch mounting pipe 10, flange 11, relief valve 14, sewage draining exit 15;
Fig. 1, Fig. 3 to Fig. 5 are the water flow switches 4 with decompression, are made up of A, B bis-functional parts.
Part A, in main body 4-1, the passage of water inlet and water outlet is not directly communicate, but separated by cover plate 4-2, when there being water flow, water can be forced promotion cover plate 4-2, simultaneously promotion seal 4-3 with impeller 4-4 and movable contact 4-9 contacted with stationary contact 4-8 or microswitch 4-7 is connected, circuit turn-on: when current are closed, water inlet is closed, and circuit also disconnects.
Part B, piston 4-12 small end has a cross through hole, and centre is also porose, during water inlet, water, by transverse holes, enters in water tank from piston 4-12 interstitial hole, during water inlet, not the entering, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase of block water, piston 4-12, large end produces back pressure, and piston 4-12 is subjected to displacement, and turns down and even closes water inlet 4-14; 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. 6 to Fig. 8 is the nonmetal injection moulding electric heater structural representation of the water flow switch that band decompression is housed; Water tank water intake is by with the water flow switch 4 of decompression, and 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 nonmetal injection moulding manufacture, and pressure is limited in 0.1 to 0.2Mpa, and just thoroughly overcoming water tank makes water tank crackle because expanding with heat and contract with cold for this, leaks water problem.
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 inside and outlet pipe are all the flexible nonmetallic tubings adopting length > 500mm, jointly form physics water resistance, guarantee to be perfectly safe with tank body.
Described electrothermal tube 6 is in metal tube, and dress heating wire, with magnesia powder by heating wire and tube wall isolated insulation, is equipped with binding post at heating wire two ends.
If by A and B of the water flow switch of band decompression, be divided into two assemblies and be contained in water tank, also within this patent protection.
