Abstract

The nonmetal blowing water-tank electric water heater of the water flow switch of band decompression is housed, water tank 8 nonmetallic materials blowing is made, and the water flow switch 4 be equipped with on inlet pipeline with decompression, be made up of A, B bis-parts: part A, in main body 4-1, the passage of water inlet and water outlet is 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; 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.

Description

The nonmetal blowing water-tank electric water heater of the water flow switch of band decompression is housed

Technical field

The present invention relates to the nonmetal blowing water-tank electric water heater of the water flow switch 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, water tank is all adopt pressure-bearing type structure, rated pressure is 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 nonmetal blowing water-tank electric water heater of the water flow switch of band decompression after improvement, be made up of shell 1, water inlet pipe 2, outlet pipe 3, the water flow switch 4 with decompression, electrothermal tube 6, water tank 8, water nozzle 9, flange 11, relief valve 14.

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 blowing to make, namely multilayer blow moulding manufacture technics inner bag is adopted, be made up of one deck or more different materials when described multilayer blow moulding refers to wall of inner container blowing, be send into the different raw material of several performance, disposal molding with multiple hopper simultaneously; And the water flow switch 4 installed on water tank water intake pipeline with decompression, simultaneously in water tank just containing arranging 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 blowing water tank reduce 0.07-0.15Mpa, realizes making water tank with nonmetallic materials blow molding process, 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 and nonmetal tank body jointly to form physics water resistance, are perfectly safe.

Fig. 2 is microswitch schematic diagram;

Fig. 6 to Figure 10 is the nonmetal blowing 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 10 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.(in accompanying drawing, spring or spring leaf 4-5, cover plate 4-6, binding post 4-10)
