Abstract

The utility model provides a high pressure buffer throat for running water, which is characterized in that a short tubular throat body is stacked with a plurality of pairs of throat cores and tongue pieces, which causes the high pressure water to buffered when passing through the buffer throat to eliminate the phenomenon of water hammer and reduce the damage created on a water faucet, a pipeline, etc. by the high pressure water. The utility model has the advantages of simple structure, convenient processing and manufacture, small size, easy installation, and long service life.

Description

High pressure buffer throat for running water

The utility model relates to a kind of tap water high-pressure buffer larynx, and particularly a kind of can be used on the high-rise water-supply line is in order to the high-pressure buffer larynx of buffering high pressure water impact.

As Chinese patent CN2059702U " automatic Regulation water-saving valve ".It is long-pending that this valve adopts valve block, valve spring and variable cross section valve pocket to reduce water flow section, to reduce hydraulic pressure, can will be adjusted into the standard pressure water of an appointment by the high pressure water that changes arbitrarily of pipeline in a certain scope.But owing in this valve spring is housed, and perishable inefficacy, the valve body Machining of Curved Surface is complicated simultaneously, and body size is big, makes application acquire a certain degree of difficulty.

It is a kind of simple in structure, easy to install that the purpose of this utility model is to provide, easily processing, the high-pressure buffer larynx that cost is low.

Main points of the present utility model are alternate several tongue pieces and the larynx cores of being equipped with in the inside of short tube shape larynx body, and wherein tongue piece is the tapered annulus of an inner ring surface, and the larynx core is the disk that a periphery has symmetrical retainingf key.Alternate tongue piece and the larynx core that is installed in larynx body inside, the high pressure water that passes through is entered between larynx core and tongue piece along the annular space between larynx core and larynx body, current are hindered by tongue piece, direction becomes along tongue piece radially, current impact to the center of circle ringwise, thereby the kinetic energy of high pressure water is consumed in impacting mutually and rubbing, through some groups of larynx cores and tongue piece, further lower the pressure of water, reached the buffering purpose.

Advantage of the present utility model is, owing to adopting tongue piece, larynx core to constitute decompression member, makes that processing and making are very simple, and has also reduced the volume of buffering larynx, also makes the lengthening in working life simultaneously, installs also very convenient.

Fig. 2 is the utility model larynx cored structure schematic representation (a) front view (b) sectional drawing

Fig. 3 is the utility model tongue piece structural representation (a) front view (b) sectional drawing

Fig. 4 is the utility model user mode figure.

Introduce an embodiment in detail below in conjunction with accompanying drawing.

As figure (1), larynx body (1) adopts the short silk of corresponding caliber, internal diameter turning is enlarged 1～1.5mm, and at one end reserve a platform (6), in order to fixing some groups of tongue pieces (2) and larynx core (3), the other end at the larynx body processes an annular groove (4), cooperates the fixedly the other end of tongue piece and larynx core with ring washer (5).

As figure (2), the larynx core adopts engineering plastics to make.Its retainingf key external diameter is consistent with processing back larynx body internal diameter.

As figure (3), tongue piece adopts engineering plastics to make, and external diameter is consistent with processing back larynx body internal diameter.The inner ring surface of annular tongue piece is made taper, during installation, a small-bore side towards water inlet, is beneficial to decompression.

Use and install as figure (4), water inlet one side of the present utility model and high pressure line are linked, water outlet one side and water tap link, and within the specific limits, the water that water tap flows out will be mild stable current, not be subjected to the influence of high pressure line pressure.

Claims

1, a kind of tap water high-pressure buffer larynx is characterized in that: the interior closed assembly of short tube shape larynx body (1) has some to larynx core (3) and tongue piece (2).

2,, it is characterized in that said tongue piece (2) for circular, and its inner ring surface is tapered as the said buffering larynx of claim 1.

3,, it is characterized in that said larynx core (3) is the disk that a periphery has several symmetrical retainingf keys as the said buffering larynx of claim 1.
