Abstract
The utility model discloses a non-return pressure relief valve used for a water heater, belonging to the technical field of valves. The non-return pressure relief valve comprises a shell, and is characterized in that a water inlet and a water outlet are arranged on the shell, a non-return device is arranged on the water outlet, and a decompressor and a pressure relief device are arranged between the water inlet and the water outlet. The non-return pressure relief valve, provided by the utility model, has the advantages of compact structure and convenience of installation, and a water supply system and the water heater are safer and more reliable in a using process through the decompressor and the pressure relief valve.
Description
Technical field
The utility model relates to the reduction valve technical field, especially relates to a kind of non-return pressure-reducing valve that is used for water heater.
Background technique
At present, all, the non-return Decompression valves realizes pressure release and decompression, even the force value in force value in the pipeline and the utensil reaches safe application performance, like water heater through being connected with reduction valve.Because two kinds of valves generation mechanical connections are not only installed very trouble, expense is big, and the joint is prone to leak, and exists potential safety hazard, high material consumption, and production and user cost are all very high; And take up room, not elegant in appearance.
Therefore a kind of appearance of the reduction valve of gathering Decompression valves and safety check is necessary.
The model utility content
The utility model is for solving the problems of the technologies described above, be that a kind of compact structure is provided, install convenient, be used for water heater non-return pressure-reducing valve.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of non-return pressure-reducing valve that is used for water heater; Comprise housing; It is characterized in that: on said housing, be provided with a water intake and a water outlet, on said water outlet, be provided with a check device, between said water intake and said water outlet, also be provided with decompressor and pressure relief device.
On said pressure relief device, also be provided with one handle, be convenient to operation, manually pressure release.
The utility model beneficial effect is compact structure, it is convenient to install, and makes water system and water heater more safe and reliable in the process of use through decompressor and pressure relief device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
With reference to shown in Figure 1; A kind of non-return pressure-reducing valve that is used for water heater comprises housing 1, on said housing 1, is provided with a water intake 2 and a water outlet 3; On said water outlet 3, be provided with a check device 4, between said water intake 2 and said water outlet 3, also be provided with decompressor 5 and pressure relief device 6.
On pressure relief device 6, be provided with handle 7, manually pressure release.
When the force value in the water system pipes during greater than the valve rated pressure, decompressor 5 beginning automatic vents decompressions make the pressure that gets in the water heater smaller or equal to setting rating value.Through being arranged on the check device 4 on the water outlet 3, prevent that aqueous reflux in the water heater is in system pipeline.When rated pressure value that the force value in the water heater is set greater than pressure relief device 6, pressure relief device 6 is opened pressure releases automatically, gets rid of unnecessary gas and pressure in the water heater.Make water system and water heater more safe and reliable in the process of using.On pressure relief device 6, be provided with handle 7, manually pressure release.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. non-return pressure-reducing valve that is used for water heater; Comprise housing; It is characterized in that: on said housing, be provided with a water intake and a water outlet, on said water outlet, be provided with a check device, between said water intake and said water outlet, also be provided with decompressor and pressure relief device.
2. a kind of non-return pressure-reducing valve that is used for water heater according to claim 1 is characterized in that, on said pressure relief device, also is provided with one handle.
