Abstract

The utility model discloses a water passage silencer, which can be arranged in a water inlet/outlet pipe of a tap and positioned in front or back of a tap valve core. The water passage silencer comprises a hollow pipe body and a guide structure arranged in the pipe body. Through the guide structure in the silencer, the water flow direction and the flowing speed are changed and limited, the pressure of the water is reduced, the agitating resonance of the water flow in a water inlet pipe is retarded, and direct impact and turbulence effect of the water flow on the water inlet pipe are eliminated so as to reduce the noise and achieve the effect of silencing inlet and outlet water at the same time without affecting the water flow rate.

Description

The water channel silencer

Technical field

The utility model relates to the technical field of water tap, refers in particular to a kind of water channel silencer of water tap in the water channel that be installed in.

Background technique

User regular meeting finds in the tap pipeline a kind of very big current sound is arranged when fetching boiling water tap, especially obvious when quiet at night, this is because the water route of water tap is an intake pipe of outside current being introduced tap by a connecting tube usually, after the throttling of leading valve body, enter outlet pipe, because the caliber of leading intake pipe is generally less, pressure increased after water entered intake pipe, flow velocity is fast, throttling via leading valve body further increases hydraulic pressure again, make and produce a kind of noise in the pipeline, research and analyse according to the professional person: the formation of noise mainly contains two kinds of situations, and the first produces a kind of turbulence noise because of the friction of bigger current of pressure and inboard wall of tube body and the resonance of agitating of current itself; It is two fast and when reaching certain value because of in-pipe flow speed, just begin vaporization, can form cavitation bubble in the water, when the pressure that is subjected to when bubble reaches a limiting value, the breakage of will exploding, and explosion time can be at very high pressure and the high speed impact ripple of the local generation of body, form the strong stream of breathing heavily, produce a kind of strong cavitation noise, the big more then noise of the flow velocity of water is also big more, this is the principal element that causes noise, therefore can abate the noise by the flowing velocity and the reduction pressure of restriction water.

The model utility content

For this reason, the purpose of this utility model is to provide a kind of water channel silencer, utilizes the expenditure and pressure effect of silencer, makes in the leading water channel that the water flows gently, reduces the generation of noise.

For achieving the above object, technical solution of the present utility model is:

A kind of water channel silencer can be located at the front and back that are positioned at leading spool in the leading inlet tube and outlet tube, and this silencer is a hollow tube and is located at the interior flow guide structure of body.

This flow guide structure forms a continuous helical guiding gutter for the inwall along hollow tube.

This flow guide structure is the annular chamber of several connections of moulding in hollow tube, respectively is formed with flow blocking piece in this annular chamber.

This flow guide structure is for laying several separately and the spoiler that staggers in hollow tube, and this spoiler tool arcuate surface.

This flow guide structure is the big chamber to the two ends convergent in one middle part of moulding in hollow tube.

This hollow tube is to combine with two parts symmetrical, and its junction is provided with buckling part.

This hollow tube is the one ejection formation.

After adopting such scheme, the utility model can be located at the front and back that are positioned at leading spool in the leading inlet tube and outlet tube, change and limit the pressure of water (flow) direction, water velocity and reduction water by flow guide structure, reduce current and in intake pipe, agitate resonance, eliminate direct impact and the action of turbulent flow of current to intake pipe, and then noise is reduced, reach the effect that the water-in and water-out noise reduction does not influence water flow simultaneously again.

Embodiment

As Fig. 1,1A, 1B, 1C is depicted as first preferred embodiment of the utility model water channel silencer, this water channel silencer can be located at advancing of tap, be positioned at the front and back of leading spool in the outlet pipe, be a hollow tube 1 and be located at flow guide structure 2 in the body, the outside dimension of this hollow tube 1 can corresponding water channel caliber of living in the internal diameter size and establish, can adopt the one ejection formation, it also can be two parts symmetrical 11,12 combine, its junction is provided with buckling part 13, this flow guide structure 2 forms a continuous helical guiding gutter 21 for the inwall along hollow tube 1, make the water that enters body 1 paste the tube wall spiral and go out along helical guiding gutter 21, guiding enters in the tap waterflow stabilization spiral, slow down current and in intake pipe, agitate resonance, eliminate direct impact and the action of turbulent flow of current, and then noise is reduced intake pipe;

Cooperate Fig. 2,2A, 2B, 2C to be depicted as second embodiment of the present utility model, with aforementioned different be that this flow guide structure 2 is the annular chamber 31 of several connections of moulding in hollow tube 1, respectively be formed with a flow blocking piece 32 in this annular chamber 31, make the water that enters body 1 stopping layer by layer and shunt through flow blocking piece 32, slowed down the impact of current to intake pipe, abate the noise, make entering in the tap of waterflow stabilization;

Cooperate shown in Fig. 3,3A, 3B, the 3C, be the 3rd embodiment of the present utility model, with aforementioned different be this flow guide structure 2 for several are set separately and the spoiler 41 that staggers in hollow tube 1, and these spoiler 41 tool arcuate surface 42, make the flow-disturbing effect of the water that enters body 1, change the direction of a stream of water, the stable arcuate surface 42 along each spoiler 41 of water is flowed out through spoiler 41, eliminate direct impact and the action of turbulent flow of current, reduce noise intake pipe;

Cooperate shown in Fig. 4,4A, 4B, the 4C, be the 4th embodiment of the present utility model, with aforementioned different be that this flow guide structure 2 is that moulding one middle part in hollow tube 1 is greatly to the chamber 51 of two ends convergent, make the water that enters body 1 through the extruding of chamber 51, loosen, extruding again, change the pressure of current, reduce the direct impact of current, reduce noise intake pipe.
