Description of drawings
Fig. 1 is the utility model structure principle chart;
Among the figure, 1 is body, and 2 is pressure cap, and 3 for transferring the stream bar, and 4 is adjustable water nozzle, and 5 is diversion cavity, and 6 is pressure stabilizing cavity, and 7 for discharging water the chamber, and 8 is delivery port, and 9 is the pilot chamber, and 10 is sliding sleeve, and 11 are the pressure regulation bar, and 12 is the level pressure spring, and 13 is plug, and 14 is water inlet.
The specific embodiment
The below further specifies the utility model with drawings and Examples:
As shown in Figure 1, body 1 top and the bottom have screwed hole, are provided with diversion cavity 5 between two screwed holes, 9 three individual cavity with through hole in chamber 7 and pilot chamber discharge water; Body about 1 is provided with water inlet 14 and delivery port 8; Water inlet 14 is communicated with diversion cavity 5 and pilot chamber 9; The chamber 7 that discharges water is communicated with delivery port 8.Pressure cap 2 screw-in bodies 1 upper screwed hole transfers stream bar 3 to screw in the internal thread of pressure caps 2, and adjustable water nozzle 4 tops are embedded on the pressure cap 2, and the bottom cylindrical cuts off the through hole in diversion cavity 5 and the chamber 7 that discharges water, the inner pressure stabilizing cavity 6 that forms; In discharge water chamber 7 and 9 through holes, pilot chamber sliding sleeve 10 is set, insert in the sliding sleeve 10 on pressure regulation bar 11 tops, and level pressure spring 12 is inserted in the bottom; Plug 13 screws in 1 time screwed hole of body.
Principle: when not having current, a certain amount of level pressure spring 12 of precommpression pulls down the pressure regulation bar to bottommost, when current enter from water inlet 14, will be by diversion cavity 5, enter pressure stabilizing cavity 6 by adjustable water nozzle 4 lateral openings and the sheared edge of transferring stream bar 3 lower surfaces to form again, then the lower outlet by adjustable water nozzle 4 enters the chamber 7 that discharges water, and is flowing into delivery port 8.
Current form very big pressure reduction (this moment, pressure stabilizing cavity 6 pressure were near delivery port 8 pressure) at the sheared edge place when entering pressure stabilizing cavity 6 by adjustable water nozzle 4 lateral openings with the sheared edge of transferring stream bar 3 lower surfaces to form, flow is also very big; This pressure reduction passes through the pressure regulating cavity same purpose at pressure regulation bar 11 two ends, this pressure reduction reaches and will compress the level pressure spring behind the certain value pressure regulation bar 11 is moved upward, so that the lower outlet of adjustable water nozzle 4 diminishes, promote thus hydraulic pressure in the pressure stabilizing cavity 6, reduce discharge, vice versa.In other words, when pressure regulation bar 11 stress balances were stablized, the pressure reduction between water inlet 14 and the pressure stabilizing cavity 6 was that a steady state value is the elastic force of precompressed level pressure spring 12.This differential pressure action is in adjustable water nozzle 4 lateral openings and the sheared edge of transferring stream bar 3 lower surfaces to form, so that the water flow that passes through is constant.And rotation transfers stream bar 3 change adjustable water nozzles 4 lateral openings can adjust the water yield with the sheared edge size of transferring stream bar 3 lower surfaces to form.
In sum as can be known, can't help pressure differential control and impact before and after it by the current size of this utility model device, transfer 3 controls of stream bar by rotation only.
