Abstract
The water heater of pressure-reducing valve is housed, is made up of water tank, electrothermal tube, pressure-reducing valve etc.; Inlet pipeline (2) is provided with pressure-reducing valve (12), pressure in water tank inlet pressure being decreased to a certain needs, and relies on the kinetic energy of water itself to make it in certain error range, keep constant pressure in water tank.
Description
Technical field
The present invention relates to the electric heater that pressure-reducing valve is housed.
Background technology
Pot-type boilers all in the world at present, be all adopt pressure-bearing type metal water tank, bear pressure and be generally 0.6Mpa, test pressure is 1.2Mpa; This pressure there will be many insoluble problems; Therefore, numerous esbablished corporation all reducing the pressure in water tank by every means, such as: the water heater that company of Haier notification number CN101825340B reduces inner liner pressure be employing two magnetic valves to reduce the pressure in water tank, not only complex structure, cost is expensive again, can not commercialization; In addition, the current whole world also without any enterprise at the in-built pressure-reducing valve of the housing of pot-type boiler, or take alternate manner to reduce the pressure in water tank.
Summary of the invention
The present invention improves the electric heater that existing metal water tank and nonmetal water tank make, for being equipped with the electric heater of pressure-reducing valve after improvement, chewing 9 by shell 1, water inlet pipe 2, outlet pipe 3, water flow switch 4, electrothermal tube 6, water tank 8, water, flange 11, pressure-reducing valve 12, magnetic valve 13, relief valve 14 form; The described water heater that pressure-reducing valve is housed, it is the restricting element installing pressure-reducing valve 12 on inlet pipeline 2, pressure in water tank inlet pressure being decreased to a certain needs, and the constant pressure relying on that the kinetic energy of water itself makes it keep in water tank within the scope of certain error, as Fig. 6.
The described water heater that pressure-reducing valve is housed,, on inlet pipeline 2, pressure-reducing valve 12 is installed, simultaneously the other magnetic valve 13 (as Fig. 5) in parallel of pressure-reducing valve 12, pressure in water tank inlet pressure being decreased to a certain needs, and the constant pressure relying on that the kinetic energy of water itself makes it keep in water tank within the scope of certain error;
Described pressure-reducing valve has various structures, (1), multiple field automatic pressure reducing valve 12-1 (Fig. 1, Fig. 2), by main body 12-1/1, porose rubber parts 12-2, has the constrictor 12-3 in multiple hole and spring 12-4 to form; Different levels constrictor, the diameter in hole is different, last one deck of water outlet, and aperture is minimum; Along with intake pressure is different, constrictor 12-1/3 interstitial hole can be blocked by rubber parts 12-1/2, and different levels are blocked, and the pressure entering water tank is different; When system line pressures is low, the kinetic energy of water is not enough to promote rubber parts 12-1/2, and water route is just completely unimpeded.
Because rubber parts 12-1/2 and constrictor 12-1/3 has a some holes, all the time can not be blocked, therefore no matter under any circumstance the design, water channel is all unimpeded, just when system hydraulic pressure height, rely on the kinetic energy of water itself to change orifice size, thus reach the object of decompression, and realize automatically regulating.
(2) piston type automatic pressure reducing valve 12-2 (Fig. 3), has the foraminate constrictor 12-2/5 in macropore side to form by housing 12-2/1, piston 12-2/2, rubber parts 12-2/3, spring 12-2/4, centre; Spring 12-2/4 pushes piston 12-2/2 all the time open, and constrictor 12-2/5 interstitial hole is opened; When system intake pressure is large, the kinetic energy by water promotes piston 12-2/2, is blocked in hole.
(3) the hand reducing pressure valve 12-3 (Fig. 4) of other industry universal also can be adopted to be made up of 12-3/1 adjusting screw(rod), 12-3/2 spring, 12-3/3 seat, 12-3/4 diaphragm, 12-3/5 push rod, 12-3/6 valve block, 12-3/7 balancing spring, as manual adjustments screw rod 12-3/1, valve block 12-3/6 can be promoted open, opening degree is different, and the pressure in water tank is just different; Can not automatically regulate after levelling.
Bear pressure for metal water tank and nonmetal Radiator material different, the minimum rated pressure > 0.1Mpa of automatic pressure reducing valve, and water tank is made respectively middle press-bearing water tank and low press-bearing water tank; For this reason, relief valve is equipped with at outlet system.
Described relief valve 14 is the mechanisms being located at outlet pipeline relieving pressure, is made up of main body 14-1, rubber seal 14-2, spring 14-3; Water tank safety can be guaranteed; Make material depending on water tank different, relieving pressure is different.
Novelty of the present invention is: electric heater is built with pressure-reducing valve or the other magnetic valve in parallel of pressure-reducing valve, within making the pressure in metal water tank reduce 0.3Mpa by 0.6Mpa, in nonmetal water tank, Pressure Drop is low to moderate below 0.1Mpa, water tank thickness can be reduced, save material, meanwhile, can not leak by crackle; Pressure is low can not explode; In addition after water tank internal pressure reduces, water tank can make by nonmetallic materials, thoroughly changes the manufacturing process of water tank.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 3 are the structure charts of automatic pressure reducing valve
Fig. 4 is the structural representation of the pressure-reducing valve of the manual adjustments that other industry is general
Fig. 5, Fig. 6, Fig. 7 are the electric heater schematic diagrames that pressure-reducing valve is housed;
Detailed description of the invention
Embodiment below in conjunction with accompanying drawing 1 to 7 is described, in accompanying 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), outlet pipe fixed pivot 7, water tank 8, water chew 9, thermometric or temperature limit switch mounting pipe 10, flange 11, pressure-reducing valve 12 (automatic pressure reducing valve 12-1 or 12-2, hand reducing pressure valve 12-3) magnetic 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; Just add a spring 12-1/4 in Fig. 2; Fig. 3 is piston type automatic pressure reducing valve; Fig. 4 be other with the hand reducing pressure valve that water mechanism uses, be not suitable for directly using on electric heater, automatically can not regulate intake pressure.
Fig. 5, Fig. 6, Fig. 7 are that the electric heater that pressure-reducing valve is housed shows; Install in Fig. 5 inlet pipeline and send out pressure-reducing valve 12, magnetic valve 13 simultaneously in parallel, 1st water inlet is by pressure-reducing valve 12, water tank is made to fill water, in multichannel water system, any one water is chewed 9 and is discharged water, and water flow switch 4 can notify that magnetic valve 13 is opened to water tank 8 moisturizing, the pressure that pressure-reducing valve 12 in parallel passes through can be very low, can make water tank pressure-bearing within 0.15Mpa; In the inlet pipeline 2 of Fig. 6 Fig. 7, pressure-reducing valve 12 is only installed, when preheating in water tank, after being warmed to about 75 DEG C, within the pressure in metal water tank 8 can be increased to 0.3Mpa, within nonmetal tank pressure can be increased to 0.15Mpa.
