Abstract
The utility model relates to an electric heater with a pressure protection valve, which comprises a liner, a water inlet pipe, a water outlet pipe, a relief valve body, a relief spring, a post rod, a rubber plain cushion, a pressure-adjusting loop coil, a guide joint, and the like, wherein the liner, the water inlet pipe and the water outlet pipe are directly communicated; and the pressure protection device consisting of the relief valve body, the relief spring, the post rod, the rubber plain cushion, the pressure-adjusting loop coil and the guide joint is assembled on one of the liner, the water inlet pipe and the water outlet pipe. When the electric heater is heated to expand or the water supply pressure raises, water flows out of the pressure protection device by relieving pressure and is led out by the guide joint.
Description
Technical field
The utility model relates to a kind of electric heater, and particularly a kind of electric heater that self has pressure protective device belongs to household electrical appliance technical field.
Background technology
Electric heater in use often will be subjected to running water or add pressure effect, the especially closed electrical water heater that thermal expansion produces, and its hydraulic pressure that will bear is bigger; Based on the consideration of safety, present numerous manufacturers have been equipped with a relief valve in the accessory at random of electric heater, when the installation of electric heater, relief valve is connected with electric heater again.
Be equipped with the mode of relief valve,,, have following drawback at least according to the experience of the applicant according to the electric heater of specialty manufacturing for many years though can reach purpose to the electric heater pressure protect:
Be easy to generate in 1 production process that accessory lacks, leakage, wrong phenomenon, management difficulty increase, the especially electric heater of different pressures grade, the relief valve setting pressure of its outfit is different certainly, place the relief valve of high setting pressure as low-pressure grade electric heater, consequence is well imagined;
The fixing link of 2 relief valves is restive, often only depends on on-the-spot installation personnel to realize; But the performance of relief valve is to be subjected to factor affecting such as installation environment, material, under the environment as frosting, may cause relief valve to produce the stifled phenomenon of ice.
3 costs are higher.
Summary of the invention
At above-mentioned deficiency; a kind of electric heater that carries pressure protective device of the utility model innovation; comprise: inner bag, outlet pipe, pressure release valve body, pressure release spring, push rod, rubbery flat gasket, pressure regulation volution, water conservancy diversion joint, U-shaped snap ring, rubber o-ring, water inlet pipe; it is characterized in that: directly be communicated with between inner bag and water inlet pipe, the outlet pipe, and therein one go up the pressure protective device that is made of pressure release valve body, pressure release spring, push rod, rubbery flat gasket, pressure regulation volution, water conservancy diversion joint be set.
The utility model is on inner bag, water inlet pipe or the outlet pipe at electric heater a pressure protective device to be set, inner bag directly is communicated with water inlet pipe, outlet pipe, when the inner container of electric water heater hypertonia, the pressure protective device of setting is understood releasing pressure automatically, reaches the purpose of pressure releasing; The water of pressure release is simultaneously drawn by a water conservancy diversion joint.Solved the present situation that the powered water heater separates with pressure protective device, simultaneously; Also reduce the production and the management cost of electric heater, solved the control difficult point problem of the relief valve installation of electric heater.The pressure protective device that makes electric heater within manufacturer's controllable state, has been eliminated electric heater in the hidden danger of installing or maintenance process may exist all the time.
Description of drawings
Fig. 1 carries the electric heater topology view of pressure protective device for the utility model.
Fig. 2 carries the partial enlarged drawing of the electric heater of pressure protective device for the utility model.
1. inner bags, 2. outlet pipes, 3. pressure release valve bodies, 4. pressure release springs, 5. push rods, 6. rubbery flat gaskets, 7. pressure regulation volutions, 8. water conservancy diversion joint 9.U shape snap rings, 10. rubber o-rings, 11. water inlet pipes among the figure
The specific embodiment
The described electric heater that carries pressure protective device of present embodiment, as shown in Figure 1 and Figure 2; The inner bag 1 of electric heater directly is communicated with outlet pipe 2 and water inlet pipe 11, and outlet pipe 2 machine-shapings have the pilot hole of a pressure release valve body 3, and pressure release valve body 3 inserts pilot hole, by rubber o-ring 10 sealings, is connected by 9 lockings of U-shaped snap ring again; Sealed by rubbery flat gasket 6 between the pressure release through hole of push rod 5 and pressure release valve body 3, compressed by pressure release spring 4, pressure release spring 4 is compressed by pressure regulation volution 7, water conservancy diversion joint 8 and the 3 sealing assemblings of pressure release valve body.
When the water in the inner container of electric water heater is added thermal expansion or pressure of supply water rising, owing to directly be communicated with between inner bag 1 and the outlet pipe 2, pressure is passed to push rod 5 places in the pressure release valve body 3 along outlet pipe 2, when elastic force that pressure produces greater than pressure release spring 4, push rod 5 will be opened, rubbery flat gasket 6 loses sealing function, water in the inner bag 1 is because the effect of being under pressure, will be excreted in pressure release valve body 3 cavitys, and along 8 discharges of water conservancy diversion joint, thereby reach the purpose of the inner liner pressure that reduces electric heater, turn pressure regulation volution 7 can change the elastic force of pressure release spring 4, thereby reaches the rated pressure when setting the electric heater use.
