Background

In the central air-conditioning system, when a circulating water pump in the system runs, the flow rate of water is suddenly changed when the electric two-way valve is opened or closed, and water flow generates pressure on the valve and the valve is closed, so that water hammer is caused, and great water flow noise is often generated.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that, when circulating water pump moves in the system, the velocity of flow that can make water when opening or closing electronic two-way valve changes suddenly, and rivers can generate pressure to the valve and close to arouse the water hammer, often can produce very big rivers noise, provide one kind for this and be used for fan coil hush air type two-way valve.

The utility model provides a technical scheme that technical problem adopted is: a mute two-way valve for a fan coil comprising: the valve body is a two-way valve, a middle hole is formed in the valve body, and sound insulation cotton is adjusted on the outer wall of the valve body.

As an optimal technical solution of the utility model: the valve body is internally provided with a streamline structure, and a vacuum layer is arranged in the side wall of the valve body.

As an optimal technical solution of the utility model: the sound insulation cotton is sound insulation sponge, one of the sound insulation cotton is provided with a crest-shaped protrusion, and the thickness of the sound insulation surface is 3-5 cm.

As an optimal technical solution of the utility model: the vacuum layer is arranged in the middle of the side wall of the valve body and is in a semi-vacuum state, and the wall thickness of the side walls on the two sides of the vacuum layer is 0.5-1 cm.

As an optimal technical solution of the utility model: the soundproof cotton is of a hollow cylindrical structure, the soundproof cotton is sleeved on the outer wall of the valve body, and the soundproof cotton has plasticity.

As an optimal technical solution of the utility model: the diameter of the middle hole is larger than the calibers of two ends of the valve body, and the control assembly of the valve body is connected to the side wall above the middle hole.

As an optimal technical solution of the utility model: the vacuum layer is a closed space, and fine honeycomb-shaped holes are formed in the soundproof cotton

The utility model has the advantages of it is following: the valve body is internally streamlined to design so that the local resistance coefficient of the valve body is reduced, the flow resistance characteristic of the valve body is optimized, meanwhile, the streamline design can also greatly reduce the generation of vortex-induced bubbles, the problem of noise caused by the bubbles is avoided, the flowing is more stable, meanwhile, the large-drift-diameter design enables the flow velocity of fluid flowing through holes in the valve to be lower under the same load condition, the noise generation probability is lower, and the noise condition can be greatly improved.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1-3, a mute type two-way valve for a fan coil includes: valve body 1, valve body 1 are two-way valve, have seted up mesopore 2 in the

valve body

1, and 1 outer wall of valve body is adjusted there is soundproof cotton 4.

Soundproof cotton 4 is the hollow cylindrical structure, soundproof cotton 4 cup joints on the outer wall of valve body 1, soundproof cotton 4 has plasticity, establish for streamlined structure inside valve body 1, establish vacuum layer 3 in the valve body 1 lateral wall, soundproof cotton 4 is soundproof sponge, establish one of soundproof cotton 4 has the crest of wave form to be protruding, soundproof surface 4 thickness is 3-5cm, vacuum layer 3 is seted up in the centre of valve body 1 lateral wall, vacuum layer 3 is the semi-vacuum state, the wall thickness of 3 both sides lateral walls in vacuum layer is 0.5-1cm, the diameter of mesopore 2 is greater than the bore at the both ends of valve body 1, the control assembly of valve body 1 connects its top lateral wall, vacuum layer 3 is airtight space, set up tiny hole on soundproof cotton 4, soundproof cotton hole
