Abstract
Water heater equipped with pressure reducing valve is made of shell, water tank, inlet and outlet pipes, electrothermal tube, pressure reducing valve, solenoid valve, water tap etc.；It is that pressure reducing valve (12) are installed on inlet pipeline (2), an or solenoid valve in parallel by pressure reducing valve, inlet pressure is decreased to pressure in the water tank of a certain needs, and makes it keep pressure in water tank constant in certain error range by the kinetic energy of water itself；To make the pressure in water tank can reduce 0.3Mpa to 0.1Mpa.
Description
Technical field
The present invention relates to the electric heaters that pressure reducing valve is housed.
Background technique
All pot-type boiler in the world at present, is all to be born pressure using pressure-bearing type metal water tank and be generally
0.6Mpa, test pressure 1.2Mpa；This pressure will appear many insoluble problems；Therefore, numerous esbablished corporations are all
Reducing the pressure in water tank by every means, such as: the hot water of company, Haier notification number CN101825340B reduction inner liner pressure
Device is to reduce the pressure in water tank using two solenoid valves, and not only structure is complicated, and cost is again expensive, cannot be commercialized；Except this it
Outside, at present the whole world also without any enterprise in the shell of pot-type boiler dress pressure reducing valve, or take other way to drop
Pressure in low flush tank.
Summary of the invention
The electric heater that the present invention makes existing metal water tank and nonmetallic water tank improves, for equipped with subtracting after improvement
The electric heater of pressure valve, by shell 1, water inlet pipe 2, outlet pipe 3, water flow switch 4, electrothermal tube 6, water tank 8, water tap 9, flange 11,
Pressure reducing valve 12, solenoid valve 13, relief valve 14 are constituted；The water heater equipped with pressure reducing valve is that decompression is installed on inlet pipeline 2
Inlet pressure is decreased to pressure in the water tank of a certain needs by the restricting element of valve 12, and by the kinetic energy of water itself make its
Within a certain error range keeps the pressure in water tank constant, such as Fig. 6.
The water heater equipped with pressure reducing valve is the installation pressure reducing valve 12 on inlet pipeline 2, while by pressure reducing valve 12 simultaneously
Join a solenoid valve 13 (such as Fig. 5), inlet pressure is decreased to pressure in the water tank of a certain needs, and by the kinetic energy of water itself
It is set to keep the pressure in water tank constant within a certain error range；
The pressure reducing valve is there are many structure, (1), multiple field automatic pressure reducing valve 12-1 (Fig. 1, Fig. 2), by main body 12-1/1,
Porose rubber parts 12-2, the constrictor 12-3 and spring 12-4 in multiple holes constitute；Different levels constrictor, the diameter in hole is not
Together, the last layer of water outlet, aperture are minimum；With intake pressure difference, constrictor 12-1/3 interstitial hole can be by rubber parts 12-1/
2 block, and different levels are blocked, and the pressure into water tank is different；When system line pressures are low, the kinetic energy of water is not enough to push
Rubber parts 12-1/2, water route are just completely unimpeded.
Since rubber parts 12-1/2 and constrictor 12-1/3 have a some holes, always can not be blocked, therefore the design without
By under any circumstance, water channel be all it is smooth, only when system hydraulic pressure is high, change throttleng surface by the kinetic energy of water itself
Product, to achieve the purpose that decompression, and realizes automatic adjustment.
(2) piston type automatic pressure reducing valve 12-2 (Fig. 3), by shell 12-2/1, piston 12-2/2, rubber parts 12-2/3, bullet
Spring 12-2/4, centre have foraminate constrictor 12-2/5 beside macropore to constitute；Spring 12-2/4 pushes piston 12-2/2 open always,
Open constrictor 12-2/5 interstitial hole；When system intake pressure is big, the kinetic energy by water pushes piston 12-2/2, and macropore is blocked up
Extremely, the water for reducing pressure flows into water tank from the aperture of constrictor 12-2/5.
(3) the hand reducing pressure valve 12-3 (Fig. 4) of other industry universals also can be used by 12-3/1 adjusting screw rod, 12-3/2 bullet
Spring, 12-3/3,12-3/4 diaphragm, 12-3/5 push rod, 12-3/6 valve block, 12-3/7 balancing spring constitute, when manually adjusting spiral shell
When bar 12-3/1, valve block 12-3/6 opening will push, opening degree is different, and the pressure in water tank is just different；It cannot be certainly after levelling
It is dynamic to adjust.
Pressure difference, the minimum rated pressure > of automatic pressure reducing valve are born for metal water tank and nonmetallic Radiator material
0.1Mpa, and middle press-bearing water tank and low press-bearing water tank is respectively prepared in water tank；For this purpose, being equipped with relief valve in outlet system.
The relief valve 14 is to be located at outlet pipeline to release the mechanism of pressure, by main body 14-1, rubber seal 14-2,
Spring 14-3 is constituted；It can ensure that water tank safety；Different depending on water tank making material, pressure of releasing is different.
Novelty of the invention is: electric heater is provided with a solenoid valve in parallel by pressure reducing valve or pressure reducing valve, makes metal
Pressure in water tank is reduced within 0.3Mpa by 0.6Mpa, and pressure is reduced to 0.1Mpa hereinafter, water can be reduced in nonmetallic water tank
Case thickness saves material, meanwhile, it will not crackle leak；Pressure is low to explode；In addition after water tank internal pressure reduces, water
Case can make of nonmetallic materials, thoroughly change the manufacturing process of water tank.
Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3 are the structure charts of automatic pressure reducing valve
Fig. 4 is the structural schematic diagram of the general pressure reducing valve manually adjusted of other industry
Fig. 5, Fig. 6, Fig. 7 are equipped with the electric heater schematic diagram of pressure reducing valve；
Specific embodiment
1 to 7 embodiment is illustrated with reference to the accompanying drawing, in attached drawing: shell 1, cold water inlet 2, hot water outlet pipe
3, water flow switch (comprising dry-reed and electronic type) 4, controller 5, electrothermal tube 6 (upper electrothermal tube 6-1, lower electrothermal tube 6-2), go out
Water pipe fixed pivot 7, water tank 8, water tap 9, thermometric or temperature limit switch installing pipe 10, flange 11,12 (automatic pressure reducing valve of pressure reducing valve
12-1 or 12-2, hand reducing pressure valve 12-3) solenoid valve 13, relief valve 14, sewage draining exit 15.
Fig. 1 and Fig. 2 is automatic pressure-reducing, and structure is different, and function is identical；A spring 12-1/4 is only increased in Fig. 2；Figure
3 be piston type automatic pressure reducing valve；Fig. 4 is other with the hand reducing pressure valve used on water dispenser structure, is not suitable for straight on electric heater
Use is connect, intake pressure cannot be automatically adjusted.
The electric heater that Fig. 5, Fig. 6, Fig. 7 are equipped with pressure reducing valve shows；Installation hair pressure reducing valve 12 in Fig. 5 inlet pipeline, simultaneously
Solenoid valve 13 in parallel, the 1st water inlet is so that water tank is filled water by pressure reducing valve 12, in multichannel water system, any one water
Nozzle 9 discharges water, and water flow switch 4 is notified that solenoid valve 13 is opened to 8 moisturizing of water tank, and the pressure that pressure reducing valve 12 in parallel passes through can be very
It is low, it can make water tank pressure-bearing within 0.15Mpa；In the inlet pipeline 2 of Fig. 6 Fig. 7, it is only mounted with pressure reducing valve 12, when pre- in water tank
Heat, after being warmed to 75 DEG C or so, the pressure in metal water tank 8 be can be improved to 0.3Mpa, and nonmetallic tank pressure can be improved
To 0.15Mpa.
