Description
Technical field
The utility model relates to a kind of electric heater, specifically belongs to have the electric heater that valve is pressed in the unidirectional deceleration of balanced type.
Background technology
The safety valve of electric heater has the interior pressure release part and the splenium branch that leaks.Outer pressure release can guarantee that inner container of electric water heater pressure is not higher than secure setting, interior pressure release then can be regulated the balance of intake pressure and inner liner pressure, when inner liner pressure surpasses certain value, a part of water in the inner bag is back to water pipe by interior pressure release passage, besides when water inlet is cut off the water supply, can guarantee to retain certain water yield in the inner bag, prevent that electric heater from burning because of lack of water is empty.Its structure of electric heater relief valve in the prior art, interior pressure releasing valve core is provided with a undergauge groove, valve core upper sleeve has its top of a turriform spring to embed the undergauge groove, the drawback that this structure causes is: 1. the assembling of the assembly of valve own and dismounting are relatively more difficult, 2. valve damage occurs and is difficult to maintenance, 3. equalizing pressure can not be regulated, 4. turriform spring manufacture process control is relatively more difficult, each is unequal to cause this spring pressure easily, can not regulate owing to pressure again, thus the balance of pressure release setting pressure in can not guaranteeing.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks, and the one way pressure-reducing valve of a kind of height rational in infrastructure, safe in utilization, stable, balance hydraulic pressure is provided, and the balanced type one way pressure-reducing valve improves the service life and the security of electric heater.
For achieving the above object:
Have the electric heater of balanced type one way pressure-reducing valve, comprise the heating water bladder, the heating water bladder connects water inlet pipe and outlet pipe respectively, is connected to pressure-reducing valve and check valve on the described heating water bladder;
Pressure-reducing valve comprises triple-valve body, is respectively pressure relief opening, normal pressure mouth and row pressure mouth, be provided with balancing pole in the triple-valve body, the balancing pole two ends are pressed on pressure relief opening, normal pressure mouth respectively, the row pressure mouth is communicated with valve body and is built in a side, the end that balancing pole peaks at pressure relief opening is with sealing gasket, be provided with an elastic mattress between balancing pole and the normal pressure mouth, the balancing pole end peaks on the elastic mattress;
Check valve comprises straight-through valve body, and straight-through valve body is provided with water inlet and delivery port, is provided with nonreturn valve core and the spring that is placed on the spool in the straight-through valve body, and nonreturn valve core peaks at the intake tunnel mouth;
The pressure relief opening of above-mentioned pressure-reducing valve can be communicated with delivery port one end of the straight-through valve body of above-mentioned check valve.
Described balancing pole is " soil " font, and the external diameter of balancing pole is less than the internal diameter of valve hole.
The end that described balancing pole peaks on the elastic mattress is a protuberance.
The top of nonreturn valve core is provided with sealing ring.
Described normal pressure mouth is communicated with water inlet pipe.
Described pressure relief opening is connected on the water pipe channel, or constitutes an integral body with delivery port one end of the straight-through valve body of check valve.
Described row pressure mouth connects drainpipe.
Described water inlet connects water inlet pipe.
Described delivery port connects the heating water bladder.
Elastic mattress between described balancing pole and the normal pressure mouth is closed isolating pad, and elastic mattress does not have through hole.
The beneficial effects of the utility model:
1, is connected to pressure-reducing valve and check valve on the above-mentioned heating water bladder, pressure-reducing valve and check valve can be communicated with formation one whole one way pressure-reducing valve, one way pressure-reducing valve can be controlled the water yield in the heating water bladder, and the water in the heating water bladder can not be flow backwards, and burns because of lack of water is empty to prevent the heating water bladder, when the heating water bladder heats, hydraulic pressure in its water courage increases, water expanded by heating, the pressure relief opening pressurized jack-up balancing pole pressure release of one way pressure-reducing valve, water is discharged by discharge outlet, makes heating water bladder's pressure balance; One way pressure-reducing valve rational in infrastructure can be released unnecessary pressure and water vapour in the heating water bladder, makes its safety, stable, and the normal pressure mouth of one way pressure-reducing valve connects water inlet pipe, and by the light water pressure-controlled, the pressure in the heating water bladder makes its balance in normal pressure;
2, the electric heater of balanced type one way pressure-reducing valve is housed, because pressure relief opening and normal pressure mouth are same source pressure, when if liquid in the heating water bladder of pressure relief opening one end or steam cause pressure to raise owing to reasons such as heating, cause water to expand and the pressure rising, owing to the purpose that realizes draining superfluous water is backed down the pressure relief opening sealing gasket in the effect of power, thereby the realization pressure release is no more than the normal pressure value with the pressure that guarantees pressure relief opening one end in heating process; And when the water of pressure relief opening one end is not heated and keeps pressure with the water of normal pressure mouth one end to be consistent; then balancing pole is motionless; sealing gasket sealing pressure relief opening can not drained phenomenon; thereby deficiency and defective that the electric heater that designs in the past must be set its fixedly pressure release value have been overcome; and the pressure release value that this balanced type pressure-reducing valve has been realized its electric heater with the pressure values of its liquid supplied or gas source the target of dynamic change; guarantee in the pressure values of its liquid of supplying or gas source when low; allow its electric heater needn't bear unnecessary big force value; and guarantee safety and protect service life of electric heater; guarantee simultaneously when normality; liquid or gas in the electric heater do not outflow, and play a kind of valve body; the effect of multipurpose.
