Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
First embodiment, as shown in fig. 1, the present embodiment provides a water heater pressure relief system, including:
the water heater comprises a water heater main body 1, wherein the water heater main body 1 is provided with a water inlet 11 and a water outlet 12;
the water using terminal 2 is connected with the water outlet 12 through a water pipe;
the pressure relief valve 3 is connected between the water using terminal 2 and the water outlet 12;
the check valve 4, the check valve 4 sets up on water inlet 11.
Specifically, during actual use, the water heater body 1 is electrically heated, so that the water inside is heated to a desired temperature. When the user uses hot water, cold water in the tap water pipe enters the water heater main body 1 from the water inlet 11 through the one-way valve 4, and hot water in the water heater main body 1 is output through the water outlet 12 and is output from the water using terminal 2 through the pressure relief valve 3.
Wherein, when the water pressure in the water heater body 1 is high, and the water terminal does not output hot water at this time. Along with the increase of the water pressure, the pressure release valve 3 is opened due to the water pressure, so that the hot water in the water heater main body 1 is discharged through the pressure release valve 3, and the water pressure in the water heater main body 1 is further reduced, so as to meet the requirement of safe use.
In addition, in the pressure relief process, the water in the water heater main body 1 is acted by the check valve 4 arranged on the water inlet 11, so that the backflow phenomenon of hot water in the water heater main body 1 caused by the output of the hot water through the water inlet 11 can be avoided, more importantly, the pressure relief valve 3 is arranged on the pipeline of the water outlet 12, and the phenomenon that the water discharge amount is too large due to the fact that the water inlet pipeline conducts and discharges too much cold water due to pressure relief water flow diversion in the pressure relief process of the water inlet pipeline is avoided.
In some embodiments, the pressure relief valve 3 may be arranged close to the water usage terminal 2 in order to facilitate the connection of the discharged pressure relief valve directly to a floor drain or sewer pipe in the user's home. Specifically, the relief valve 3 may be installed near the water use terminal 2 of the water heater main body 1 on the water path for different types of water use terminals 2 installed in the home of the user, and the following description will be given by way of example.
As shown in fig. 1, the water terminal 2 includes a water mixer 21 and a shower head 22, the shower head 22 is connected to the water mixer 21, and the pressure relief valve 3 is connected between the water mixer 21 and the water outlet 12.
Specifically, in a general case where the water heater main body 1 is placed in a bathroom, which is generally provided with the water mixer 21 and the shower head 22, the pressure release valve 3 may be connected between the water mixer 21 and the water outlet 12, and the pressure release valve 3 is disposed close to the water mixer 21.
Whereas the mixer 21 is usually mounted at a level below the level of the water heater body 1, and the mixer 21 is usually close to a floor drain in the bathroom. Therefore, water flowing out in the pressure relief process of the pressure relief valve 3 can quickly flow into the floor drain.
The pressure release valve 3 is also connected with a drain pipe 30, the drain pipe 30 can be directly inserted into a floor drain to prevent water from flowing to the ground, and meanwhile, the drain pipe 30 is short in length and beneficial to reducing cost.
Preferably, since the mixer 21 is generally provided with a decorative shell, the pressure relief valve 3 may be provided directly on the hot water inlet of the mixer 21, so that the decorative shell of the mixer 21 is used to cover the pressure relief valve 3, thereby enhancing the appearance.
Alternatively, as shown in fig. 2, the water use terminal 2 is a hot water tap, and the pressure release valve 3 is disposed below the hot water tap.
Specifically, under the condition that the hot water cold head is arranged close to the water heater main body 1, the pressure release valve 3 can be arranged below the hot water faucet, and the hot water faucet is usually arranged at the upper part of the washbasin, so that the pressure release valve 3 can be arranged below the washbasin.
In addition, in order to facilitate the drainage of the pressure release valve 3, the drainage pipe connected to the pressure release valve 3 can be directly connected to a sewer pipe on the washbasin, so as to avoid the turbulent flow of the water flowing out from the pressure release.
In some embodiments, the structure of the pressure relief valve 3 is simplified in order to achieve pressure relief. As shown in fig. 3, the relief valve 3 includes:
a pressure relief opening 311 is formed in the pipe wall of the first connecting pipe 31;
a second connecting pipe 32, the second connecting pipe 32 being disposed on the pipe wall of the first connecting pipe 31 and being communicated with the pressure relief opening 311, the second connecting pipe 32 being further provided with a water outlet 321;
a plug 33, wherein the plug 33 can slide in the second connecting pipe 32 and is used for selectively blocking the pressure relief opening 311;
and an elastic member 34, wherein the elastic member 34 is used for applying an elastic force to the plug 33 towards the pressure relief opening 311.
Specifically, during actual installation, the pressure relief valve 3 is connected between the water outlet 12 and the water terminal 2 through the first connection pipe 31, and when pressure relief is required, the water pressure in the first connection pipe 31 pushes the plug 33 to move against the elastic force of the elastic component 34. And the stopper 33 is moved away from the pressure relief port 311 so that the water in the first connection pipe 31 flows into the second connection pipe 32 and is discharged from the discharge port 321.
In one embodiment, the plug 33 is provided with a connecting rod 331, and the connecting rod 331 is hermetically extended to the outside of the second connecting pipe 32. Specifically, the plug 33 can be guided to reciprocate by the connecting rod 331. Also, a pull handle 35 may be further provided on an outer end portion of the connection rod 331 to manually open the relief valve 3 by the pull handle 35.
In order to facilitate the installation of the elastic member 34, the elastic member 34 is a spring fitted over the connection rod 331, and the spring presses between the end of the second connection pipe 32 and the plug 33 so that the plug 33 is always biased toward the relief opening 311 by the spring.
Compared with the prior art, the utility model discloses an advantage is with positive effect: through dispose the check valve on the water inlet to avoid the water in the water heater main part to flow backward because of water pressure, meanwhile, the delivery port configuration relief valve of water heater main part, and then when water pressure in the water heater main part is great, the hot water in the water heater main part will be discharged via the relief valve, and then avoids water conservancy diversion in the water pipe and discharge together with the pressure release water, like this, alright reduce the outer discharge of water when satisfying normal pressure release, and then improve user experience nature.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
