Abstract
The utility model relates to a variable volume constant pressure automatic compensation regulator used in a fluid conveying pipeline, and when flow increases, the pressure also increases correspondingly or keeps constant so as to cause the end service pressure to be kept constant. The utility model is composed of a static pressure regulation device and a dynamic pressure automatic compensation device. The utility model is mainly characterized in that an outlet point is provided with a throttling device, so that when flow increases, a pressure difference generates and acts on an upper and a lower diaphragms, and the opening degree of a valve clack is regulated to cause the service pressure to increase with the increasing of the flow.
Description
The utility model relates to a kind of valving that is used for fluid-transporting tubing, particularly a kind ofly makes the also corresponding increase of pressure or keeps constant when flow increases, thereby can make terminal service pressure keep the automatic compensated regulator of constant variables constant voltage.
The utility model prior art is that " bivalve plug water supply reduction valve " (CN2130225Y), is made of valve gap, valve seat, adjusting screw rod, spring, interlock spool and bivalve plug, and pressure ratio can be regulated significantly before and after it.The claimant also retrieves a kind of fine setting diaphragm type proportional pressure-reducing valve (CN2213264Y), is made up of valve body, bottom flange, stop nut, flap, valve seat, spool, spring, bonnet and adjustable lever, is used for general water system and can obtains desirable working pressure.Above-mentioned two kinds of reduction valve only can make the front and back variation in pressure in proportion, but there is no the function of dynamic pressure Compensation Regulation.
The utility model purpose be design a kind of during with the micrometeor set minimum pressure of supply water be benchmark, and can carry out pressure according to actual water supply flow size and compensate automatically, flow increases the corresponding increase of pressure of supply water, makes the terminal service pressure of water system pipe network keep the automatic compensated regulator of constant variables constant voltage.
The utility model project organization is: the automatic compensated regulator of a kind of variable constant voltage, form by static pressure controlling device and the automatic compensation adjustment device two-part of dynamic pressure, the static pressure controlling device is by screw press, the spring marshall springs, overcoat constitutes, spring seat is positioned on the spring and the overcoat that coexists, the screw press rotation set is on spring seat, the automatic compensation adjustment device of dynamic pressure is by the pedestal of fixedlying connected with overcoat in the static pressure controlling device, upper diaphragm, following diaphragm constitutes, pedestal is provided with water intake D1 and water outlet D2, water outlet D2 adopts the jet pipe that can produce jet, the upper diaphragm circle edge is fixed between overcoat and the pedestal, withstand on the spring above the upper diaphragm, it is connected with the following diaphragm that is fixed on base bottom below by being communicated with bar, spool is fixed on and is communicated with the bar lower end and is positioned at down on the diaphragm, also is shaped on the split channel that is communicated with waterexit end and valve chamber and modulating valve is housed thereon and is communicated with jet pipe pressure chamber and lower membrane chamber or upper diaphragm chamber passage in pedestal.
The diverter valve effect is to be used to regulate the pressure compensation amount, according to opening of valves size decision pressure compensation amount.On jet pipe pressure chamber, can connect two passages (12), one tunnel logical upper diaphragm chamber, another Lu Tong lower membrane chamber.Its Placement also can be that passage (12) only is communicated with a diaphragm chamber, simultaneously with being communicated with bar (7) with upper and lower two diaphragm chamber's conductings.Jet pipe and pedestal (6) can be splits.
The utility model advantage is owing at the water outlet place throttling arrangement is arranged, when increasing, flow produces a pressure reduction that increases with flow, and act on diaphragm and pressure is increased when being installed in the fluid line with flow, adapt to the fluid system-head curve, make terminal service pressure keep constant.
Accompanying drawing is the utility model sectional structure chart.
Embodiment: the automatic compensated regulator of a kind of variable constant voltage, form by the static pressure controlling device on top and automatic compensation adjustment device two-part of dynamic pressure of bottom, the static pressure controlling device on top is by screw press 1, spring seat 2, spring 3, overcoat 4 constitutes, spring seat 2 is positioned on the spring 3 and the overcoat 4 that coexists, can move up and down screw press 1 rotation set on spring seat 2, the automatic compensation adjustment device of dynamic pressure is by the pedestal 6 of fixedlying connected with overcoat 4 in the static pressure controlling device, upper diaphragm 5, following diaphragm 8 constitutes, pedestal 6 is provided with water intake D1 and water outlet D2, water outlet D2 adopts the jet pipe that can produce jet, it is big that this jet pipe is two, middle little pair of flared horn shape, upper diaphragm 5 circle edge are fixed between overcoat 4 and the pedestal 6, withstand on above the upper diaphragm 5 on the spring 3, it is connected with the following diaphragm 8 that is fixed on pedestal 6 bottoms below by being communicated with bar 7, spool 9 is fixed on connection bar 7 lower ends and is positioned on the following diaphragm 8, also being shaped on the split channel 11 that is communicated with waterexit end and valve chamber and modulating valve 10 being housed and connection jet pipe pressure chamber and upper diaphragm chamber passage 12 thereon in pedestal 6, is hollow in order on being communicated with in the middle of the connection bar 7, lower membrane chamber.Below in conjunction with its working principle of description of drawings: when pipeline inner fluid flow is less than normal, P
0, P
2, P
3About equally, thus by the upper and lower regulating spool aperture that moves of top static pressure controlling device regulating spool controlling mechanism, keep outlet pressure constant; When increasing with water flow, P
2＜P
3, its difference increases with flow, make down diaphragm produce one with the big or small relevant downward pulling force of flow, making the increase of spool aperture is P
3Increase, thereby make terminal service pressure constant.
