Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 5, the safety relief anticreeper of water heater of the present invention, including
Valve body 1 and tube body 2, the valve body 1 are threadedly coupled with tube body 2, in a preferred embodiment of the invention, the tube body 2 and valve body 1
Between be equipped with the asbestos washer 11 for sealing and be used to support the Water pipe bracket 12 of tube body 2, prevent tube body 2 too long and shake
It shakes, the tube body 2 is also outer to be cased with stainless steel tube 13, prevents water mark from getting rusty or breeding others on the outer surface of tube body 2 thin
Bacterium.In addition, the top of the tube body 2 is equipped with the water pipe plug 9 of adaptation tube body 2, it is preferable that the tube body 2 and water pipe plug 9
It is insulator made of insulating materials PPR.An O-Sealing Rings 14 are additionally provided between water pipe plug 9 and tube body 2, then by water
Pipe plug 9 and tube body 2 heat, and form the anti-electric basic device for having connection features.
PPR pipe is called three type PA tubes, atactic copolymerized polypropene, becomes pipe through extrudable using atactic copolymerized polypropene
Material can also be molded as pipe fitting.Ethylene is most common monomer, it causes the change of polypropylene physical property.With pp homopolymer
It compares, random copolymer improves optical property, improves shock resistance, increases flexibility, fusion temperature is reduced, thus
Also reduce hot melt jointing temp.PPR pipe has energy-saving compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement
Material, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling (avoid encrustation, get rusty caused by water quality " secondary dirt
Dye "), heat-resisting, pressure-resistant, long service life the advantages that.It is demonstrated experimentally that the production energy consumption of energy saving PPR pipe is only the 20% of steel pipe, and
And its thermal coefficient is low [0.2W/(m.K)], is also only the 1/200 of steel pipe, will greatly reduce heat damage applied to hot-water heating system
It loses;The long-term use temperature of PPR pipe can reach 95 DEG C, and short-period used temperature is being 70 DEG C using temperature up to 120 DEG C, work
Under the conditions of pressure is 1.2MPa, long-term to be used continuously, the service life was up to 50 years or more;PPR pipe is easy for installation, is connected firmly, PPR tool
There is good welding performance, tubing, pipe fitting can be used hot melt and connect with electric smelting, and easy for installation, connector is secured, connecting portion
Intensity is greater than the intensity of tubing itself.
As shown in figure 4, being equipped with intake tunnel 3 and outer pressure release passage 4 in the valve body 1, the intake tunnel 3 is equipped with interior
Valve port 31 is let out, the outer pressure release passage 4 is equipped with the valve port 41 that leaks, is equipped in the intake tunnel 3 for balancing in water heater
Valve module 5 is let out in portion's pressure, the interior valve module 5 of letting out is let out valve core 51 and arrived for discharging water heater internal pressure including interior
Let out pull rod 52 in pipeline, it is described in let out pull rod 52 with outer shaft sleeve have in let out spring 53, it is described in let out valve core 51 and let out with interior
It is equipped between valve port 31 and lets out sealing valve port pad 54 in valve port 31 for letting out in sealing;5 housing of valve module is let out in described to be used for
The starting spring 8 of valve module 5 is let out in promotion, in the present embodiment, specifically, is equipped in intake tunnel 3 and is used to support fixation
Start the support base 32 of spring 8, the adjusting nut 33 for letting out pull rod 52 in fixed, adjusting nut 33 are additionally provided on the support base 32
The elasticity of spring 53 is let out in adjustable.When water heater can gradually rise due to constantly heating internal pressure, work as internal pressure
Less than the interior tension for letting out spring 53, then in let out valve core 51 by it is interior let out sealing valve port pad 54 seal in let out valve port 31, have single
To valve function, this function mainly prevents the water inside water heater from falling in the non-water receiving pipe of intake tunnel 3 or anhydrous intake tunnel 3
Stream.When internal pressure is greater than the interior tension for letting out spring 53, then in let out pull rod 52 and move down, then the opening of valve port 31 is let out in meaning,
Water heater internal pressure can be discharged into intake tunnel 3 at this time, play a part of balancing water heater internal pressure.And interior let out valve group
Starting spring 8 is cased with outside part 5, the other end of starting spring 8 is connected with support base 32, when water inlet external pressure is greater than starting spring
When 8 tension, will push and let out that valve module 5 is whole to be shifted up in entire, at this time in let out valve core 51 with interior valve port 31 of letting out from connecing
Closed condition conversion is touched to isolated state, i.e., interior to let out the opening of valve port 31, outside water inlet then flows into water heater.
As shown in figure 4, and being equipped with leak valve module 6 and outer drain port for water heater overvoltage protection in outer pressure release passage 4
7, the valve module 6 that leaks includes leak valve core 61 and the pull rod that leaks for discharging water heater internal pressure to outer drain port 7
62, the pull rod 62 that leaks leaks spring 63 with outer shaft sleeve, and the one end for the spring 63 that leaks is limited by the valve stop nut 65 that leaks,
And the stroke for the spring 63 that leaks is controlled by the valve stop nut 65 that leaks, the size of stroke is exactly the pressure value that control leaks.
The sealing valve port pad 64 that leaks being equipped between valve core 61 and the valve port 41 that leaks for sealing the valve port 41 that leaks that leaks.At this
In the embodiment of invention, it is equipped with the sealing nut 42 for sealing outer pressure release passage 4 in the tail end of outer pressure release passage 4, it is described outer
It lets out pull rod 62 and is fixedly connected with handle 10 by handle fixed pin 101 across sealing nut 42, meanwhile, handle 10 can be drawn leaking
Certain angle is rotated on bar 62, and pulls handle 10 that the pull rod 62 that leaks can be driven to move right, and realizes the mesh of manual pressure release
's.When the pressure value in water heater is not up to critical value, the valve core 61 that leaks is due to the elasticity tension by the spring 63 that leaks
And be compressed tightly against and leaked on valve port 41 by the sealing valve port pad 64 that leaks, form the state for the sealing of valve port 41 that leaks;Work as hot water
When intake pressure is excessively high or excessively high due to continuous heating internal pressure, pressure can not be balanced by interior valve module 5 of letting out, at this time pressure
When value is greater than the tension for the spring 63 that leaks, the valve port 41 that leaks is opened, and pressure is discharged by outer drain port 7, forms over-voltage to water heater
Protection.When long-time does not use water heater, can also there be certain pressure inside water heater, when reusing water heater,
User can pull handle 10, and then the pull rod 62 that leaks is pulled to carry out manual pressure release to water heater, guarantee safety.
In addition, having pawl on the excircle of outer drain port 7, connection PE or PVC hose can be facilitated, conveniently leak and release stress
When water flow discharge.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
