Description
Technical field
The utility model relates to a kind of water heater burn-proof device, belongs to the improvement technology that improves water heater safety's performance.
Background technology
At present, the no anti-scald functions of the water heater of the market sale overwhelming majority, method of supplying water is that manual left rotation and right rotation is mixed water valve, 75 ℃ of high-temperature water that flow out in the inner bag is mixed adjusting re-use after suitable with running water in the inlet pipeline.In the use because the continuous variation of discharge and hydraulic pressure, have to adjust once more mix water valve the phase reach the effect of wanting, accidentally promptly have in the adjustment process and be higher than 55 ℃ of high-temperature water outflows the people is scalded.In order to solve the sometimes hot and sometimes cold phenomenon of this water outlet, a kind of thermostat is arranged at present, it is installed on the electric heater intake-outlet, thereby makes the delivery port water temperature stability, has reached the purpose of constant temperature bathing basically.But the weak point of this technical scheme is, just in case the thermostat damage is malfunctioning, also can monolaterally has high-temperature-hot-water (or low-temperature cold water) to flow out the people is scalded, and influences the safe in utilization of consumer.
Summary of the invention
The purpose of the utility model is to consider the problems referred to above and provides a kind of installation environment to be required low, and easy operating can guarantee the burn-proof device of closing automatically when the delivery port water temperature is higher than 55 ℃, realizes the water heater burn-proof device of the target of comfortable bathing safety bathing.
In order to achieve the above object; The technical scheme that the utility model adopts is: a kind of water heater burn-proof device; It is characterized in that comprising valve body, spring, piston, hold-down nut, temperature-sensitive housing and temperature sensor with the outlet pipe threaded engagement of mixed water valve; Outside said valve body, be provided with the external screw thread that is connected with gondola water faucet flexible pipe internal thread, in valve body, be provided with stepped hole; Said hold-down nut is installed on the step at water inlet place of stepped hole, on hold-down nut, is provided with the through hole that is communicated with outlet pipe and valve body; Said temperature sensor is installed in the temperature-sensitive housing, and an end of said piston stretches in the temperature-sensitive housing and receives the axial promotion of temperature sensor, the temperature-sensitive housing be installed on the hold-down nut and with outlet pipe and valve body matched in clearance; Said spring is positioned at the delivery port of stepped hole; Spring one end is resisted against on the step in the delivery port; It is H that the other end that the other end stretches out delivery port and support piston makes the end of piston and the gap between the delivery port; The H value in said gap is consistent with the warm numerical value of limit, and piston receives the diameter of spring-supported end diameter greater than the delivery port of stepped hole.
Outside said temperature-sensitive housing, be arranged with spacer sleeve, an end of said spacer sleeve and temperature-sensitive housing against, the other end and hold-down nut against.
On the step at the water inlet place of said stepped hole, be provided with packing ring, said packing ring is positioned at the top of hold-down nut.
The utility model advantage compared with prior art is: owing to adopted the structure of controlling temperature of pure machinery; Do not receive the failure effect of voltage, hydraulic pressure and electrical part; Effectively guaranteed the sensitivity of temperature required control, malfunctioning in the use like thermostat or water admixing device, when the hot water of outflow is higher than 55 ℃; Can moment close delivery port, the assurance consumer's is safe in utilization.Simultaneously, dismounting, cleaning, replacing are very convenient, and applicable surface is very wide.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Like Fig. 1, shown in 2; A kind of water heater burn-proof device; The utility model characteristics are valve body 2, spring 1, piston 3, hold-down nut 4, temperature-sensitive housing 7 and the temperature sensors 8 that comprise with outlet pipe 9 threaded engagement of mixed water valve 10; Outside said valve body 2, be provided with the external screw thread 22 that is connected with gondola water faucet flexible pipe internal thread, in valve body 3, be provided with stepped hole 21; Said hold-down nut 4 is installed on the step at water inlet 211 places of stepped hole 21, on hold-down nut 4, is provided with the through hole 41 that is communicated with outlet pipe 7 and valve body 2; Said temperature sensor 8 is installed in the temperature-sensitive housing 7; Temperature sensor 8 is processed by multiple composite material; One end of said piston 3 stretches in the temperature-sensitive housing 7 and receives the axial promotion of temperature sensor 8, temperature-sensitive housing 7 be installed on the hold-down nut 4 and with outlet pipe 9 and valve body 2 matched in clearance; Said spring 1 is positioned at the delivery port 212 of stepped hole 21; Spring 1 one ends are resisted against on the step in the delivery port 212; It is H that the other end that the other end stretches out delivery port 212 and support piston 3 makes the end of piston 3 and the gap between the delivery port 212; The H value in said gap is consistent with the warm numerical value of limit, and piston 3 receives the diameter of spring-supported end diameter greater than the delivery port 212 of stepped hole 21.
During work, normal condition is mixed the hot water that flows out after water valve mixes and is flowed in the stepped hole 21 of valve body 2 through the through hole 41 that mixes on water valve outlet pipe 9, temperature sensor shell 7, the hold-down nut 4, and the piston 3 under spring 1 acts on flows out with valve body 2 gap H again.
Damage like attemperating unit malfunctioning, when the hot water temperatures in the outlet pipe 9 that mixes water valve of flowing through this moment are higher than human body and scald 55 ℃ of temperature, because the temperature sensor 8 of conduction of heat in temperature-sensitive housing 7; Make temperature sensor 8 axial elongations; Driven plunger 3 overcomes the pressure of spring 1, and making the gap H between piston 3 and the valve body 2 is 0, moment sealing delivery port 212; High-temperature water can not flow out, and has avoided the consumer is scalded.
During installation, earlier temperature sensor 8 is press-fited in the axial long hole to the temperature-sensitive housing 7, axially displaceable piston 3 is equipped with in the bottom, hole, thereby forms the temperature module; With the temperature module and hold-down nut 4 screw-internal thread fit, form water heater burn-proof device assembly part again.
In the present embodiment,, outside said temperature-sensitive housing 7, be arranged with spacer sleeve 6 for fixing and regulate the size of gap H value, an end of said spacer sleeve 6 and temperature-sensitive housing 7 against, the other end and hold-down nut 4 against.
On the step at water inlet 211 places of said stepped hole 21, be provided with packing ring 5, said packing ring 5 is positioned at the top of hold-down nut 4.
