Description
Technical field
The utility model relates to a kind of throttling set.
Background technology
Be used in a kind of throttling set in the anti-penetration water purifier condensed water discharge pipe; Be commonly referred to the waste water ratio; This waste water of prior art is than all adopt aperture or elongated tubular (also claiming kapillary) throttling basically, for the then aperture of adopting small structure basically between 0.5 millimeter～0.8 millimeter; For adopting the elongated tubular structure, then pipe range is many in 100 millimeters, and bore is generally between 1 millimeter～2 millimeters, and elongated tubular can be straight tube-like or tubulose in the shape of a spiral.This area the professional know, according to fluid mechanics principle, when adopting small structure mainly be lean on water flow section long-pending reduce to reach the throttling purpose; Frictional force and the long-pending dual function that reduces of water flow section of mainly leaning on the elongated tubular inwall to produce when adopting the elongated tubular structure reach the throttling purpose.Above-mentioned waste water is roughly under the pressure of 0.5MMPa than at intake pressure, and the drain discharge of its nominal has 300mL/min, 400mL/min, 500mL/min, 600mL/min, 700mL/min, 800mL/min, 900mL/min, 1000mL/min.On traditional anti-penetration water purifier, the different waste water ratio of these drain discharges is arranged, can meet the demands, that is to say that this is a mature technology.
But, shortage of water resources, water saving is one of direction of industry technical development, in other words, condensed water should reduce as the flow of discharge of wastewater significantly.One skilled in the art will appreciate that if adopt the principle of small structure, drain discharge is reduced significantly, will reduce the diameter of aperture significantly.When drain discharge is reduced to 50ml/min, through calculating, hole diameter will be reduced to below 0.2 millimeter.On the other hand, when the diameter of aperture is very little, just occur easily stopping up, safety is just poor.The reason of stopping up has two, and the one, thing is stifled, and the small particle that possibly exist in the water is with little hole plug; In a single day the 2nd, gas is stifled, bubble occurs in the water, gas rests in the aperture, and current are difficult to therefrom flow through.The aperture is more little, and the situation that occurs stopping up will be serious more.If adopt the elongated tubular structure to reduce flow through the length of lengthening elongated tubular, then the length of elongated tubular will be oversize, causes cost to heighten, and do not have practical value.So, the waste water ratio that adopts the principle of existing waste water ratio to design low discharge be insecure or cost on unacceptable.
The utility model content

In order to solve the problems of the technologies described above, the technical scheme that the utility model provided is: a kind of throttling set comprises body, orifice plate and end socket; One end of said body is provided with big opening, and the other end is provided with pipe interface; One end of said end socket and the big opening of body are tightly connected, and the other end is provided with pipe interface; Said orifice plate is arranged in the inner chamber of body; Said orifice plate is provided with at least ten orifice bores; Said orifice bore is a through hole; Whole orifice bores on the said orifice plate are connected to become a single pass water stream channel through the part near the orifice plate both sides.
A kind of throttling set also comprises gasket; Said orifice plate is provided with at least two, and gasket is provided with at least one; Said orifice plate and gasket respectively are arranged in the inner chamber of body; Said gasket is provided with a gasket hole; Said gasket hole is a through hole.
The minimum place of the orifice bore diameter on the said orifice plate is 0.6～2.0 millimeter, preferred 0.8～1.0 millimeter.
The both sides of said orifice plate also are provided with a plurality of diversion grooves; Said diversion groove is communicated with two orifice bores on the orifice plate, perhaps be communicated with on the orifice plate orifice bore and near a through hole on the part of orifice plate both sides.
A kind of throttling set also comprises backing plate; Said backing plate is provided with a backing plate hole; Said backing plate hole is a through hole; One side of said backing plate is close to end socket, and opposite side is close to gasket or orifice plate.
A kind of throttling set also comprises the silk screen or the fiber filter material of the inlet end that is arranged on body, stops up inner water stream channel so that prevent the PM for particulate matter in the sealing.
Said silk screen or fiber filter material are connected with shim; Said backing plate is provided with and prevents that silk screen or fiber filter material be close to the convex tendon of backing plate, perhaps backing plate be provided with can water guide diversion trench.
After having adopted technique scheme; The utlity model has following beneficial effect: the whole orifice bores on the orifice plate of (1) the utility model are connected to become a single pass water stream channel through the part near the orifice plate both sides; This structure can be when intake pressure is about 0.5MPa be reduced to 50～100ml/min with the drain discharge of the utility model; And keep the section area of water stream channel bigger; Or keep the diameter in water stream channel cross section bigger, and effectively avoid water stream channel to stop up, make the less a kind of throttling set of drain discharge can reliability service; Finally make little waste water reverse osmosis water purifier successfully to come out, be embodied as the purpose of anti-penetration water purifier water saving.
(2) the utility model compact dimensions, volume is little, cost is low, thereby is convenient in little space, can install and use, more owing to low cost being easy to accepted by market.
(3) the utility model is provided with silk screen or fiber filter material at feed-water end, thereby it is inner to stop that effectively PM for particulate matter gets into a kind of throttling set.
