Description
Technical field
The utility model relates to a kind of float valves, specially float valve device technical field.
Background technique
A water boiler product (shape is as shown in Figure 1) needs a part in actual use to realize following function
Can, water boiler is sealed when supplying water, port help is opened when draining and is drained, and size is necessary
It can be installed to inside water boiler.Due to present on the market not specifically for the product of this functional requirement of water boiler, so
Must designed, designed go out a float valve to realize the requirement of water boiler.
Utility model content
The purpose of this utility model is to provide a kind of float valves, to solve the problems, such as that above-mentioned background technique exists.
To achieve the above object, the utility model provides the following technical solutions: a kind of float valve includes outer main body 1, glue
First 2, floating ball 3, O-ring 4 and coupling 5, outer main body 1 are a metallic object structures, and outer main body 1 has port 1-1, port 1- above
1 with communicated inside outer main body 1, outer main body 1 is internally provided with floating ball 3, and rubber head 2 is mounted on the corresponding position of the upper surface of floating ball 3
It sets, the bottom of floating ball 3 is provided with coupling 5, and coupling 5 is connect by screw thread with outer main body 1, makes rubber head 2, floating ball 3 and O-ring
4 are wrapped in inside outer main body 1, and outer main body 1 and 5 junction of coupling are provided with O-ring 4.
Preferably, the rubber head 2 is made of food grade silicone material, effect is when contact with outer main body 1
Realize sealing；
Preferably, the floating ball 3 is made of food grade plastic, effect is to float at work；
Preferably, the coupling 5 is metallic object structure, coupling 5 is provided with connecing of connecting with water boiler above
Mouth 5-1.
Compared with prior art, the utility model has the beneficial effects that its structure designs advantages of simple, water boiler is supplied
When water seal and drain when open function realization it is targeted, do not need additional operation can realize automatically water boiler draining and
Sealing function.
Detailed description of the invention
Fig. 1 is water boiler schematic diagram of product structure in the utility model background technique；
Fig. 2 is the decomposition texture schematic diagram of float valve in the utility model；
Fig. 3 is the composed structure schematic diagram of float valve in the utility model.
In figure: main body 1, rubber head 2, floating ball 3, O-ring 4 and coupling 5.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 2-3, the utility model provides a kind of technical solution: a kind of float valve include outer main body 1, rubber head 2,
Floating ball 3, O-ring 4 and coupling 5, outer main body 1 are a metallic object structures, and outer main body 1 has a port 1-1 above, port 1-1 with
It being communicated inside outer main body 1, outer main body 1 is internally provided with floating ball 3, and rubber head 2 is mounted on the upper surface of floating ball 3 corresponding position,
The bottom of floating ball 3 is provided with coupling 5, and coupling 5 is connect by screw thread with outer main body 1, wraps rubber head 2, floating ball 3 and O-ring 4
It is rolled in inside outer main body 1, and outer main body 1 and 5 junction of coupling are provided with O-ring 4.
Preferably, the rubber head 2 is made of food grade silicone material, effect is when contact with outer main body 1
Realize sealing；
Preferably, the floating ball 3 is made of food grade plastic, effect is to float at work；
Preferably, the coupling 5 is metallic object structure, coupling 5 is provided with connecing of connecting with water boiler above
Mouth 5-1.
The working principle of the present embodiment is as follows: using float valve when working in water boiler, first using sealant tape or
Interface at the top of the interface of float valve and the liner of water boiler is connected and realizes sealing by person's sealant.To water boiler supply water when
It waits, the top that water level slowly rises to water boiler liner enters float valve, and floating ball 3 drives rubber head 2 one under the promotion of hydraulic pressure at this time
It rises and floats and contacted with outer 1 inner surface of main body, water boiler is made to realize sealing；When draining, water drives floating ball 3 to decline, this
When rubber head 2 separated with outer 1 inner surface of main body, gap is generated inside float valve, enters air inside water boiler from port, is helped
Water boiler is helped to realize draining.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
