Abstract
The utility model discloses a dynamic flow balancing valve, which mainly comprises a valve body (1), a valve cover (2), spools I, II and III (3, 4 and 5), a movable valve (6) and a spring (7). The spool I (3) is arranged on the rear of a valve cavity; the spool II (4) is arranged in the front of valve cavity; a diameter-invariable channel (8) is formed between an outer wall of the spool II (4) and the wall of the valve cavity; a spacing channel between the spool I (3) and the spool II (4) is called a diameter-variable channel (9); the spool III (5) is connected inside the spool I (3); the movable valve (6) is arranged inside the spool II (4); an outer wall of the movable valve (6) and an inner wall of the spool II (4) and an inner wall of the movable valve (6) and an outer wall of the spool III (5) are arranged in sliding fit connection; and the spring (7) is fixed between the spool III (5) and the movable valve (6). The dynamic flow balancing valve has the advantages that: the water flow diameter is changed by adopting the principle of the movable valve so as to achieve dynamic balance of flow. The tests prove that the accuracy of the balanced flow is within 10 percent.
Description
Technical field:
The utility model relates to a kind of valve, specifically is a kind of dynamic flow balance valve.
Background technique:
With the tap water is example, and it is very big to flow out the water yield sometimes in the water pipe, and suddenly, it is very little that the water yield that flows out becomes again, the generation of this situation, be because the hydraulic pressure in the water pipe produced change due to.In actual life and industrialized production, it is certain stable that its flow will keep, can not the time little when big, therefore, flow balance valve is installed in pipeline, carry out to ensure the favourable of follow-up life or process water.Existing common equilibrium valve, because of its structural reason, in actual use, the water-outlet quantity of its peace-keeping Hengshui pipe is very undesirable, more can not regulate automatically and the balance rate of discharge.
The model utility content:
The technical problems to be solved in the utility model is, can not regulate problem with the balance rate of discharge automatically at existing common equilibrium valve, and a kind of dynamic flow balance valve is provided.This dynamic flow balance valve can solve the problem of automatic adjusting and balance rate of discharge preferably.
Technical solution of the present utility model is:
A kind of dynamic flow balance valve, mainly be by valve body, valve gap, spool I, spool II, spool III, moving valve and spring are formed, be provided with valve pocket in the valve body, be characterized in, spool I is the bottle cap shape that the bottom has the undergauge hole, be fixed on the valve pocket rear portion, the outer wall of spool I and valve cavity wall are that sealed type is adjacent to together, spool II is the bottle cap shape that top board has the undergauge hole, be fixed on the front portion of valve pocket, leave passage between the outer wall of spool II and the valve cavity wall, be called not variable diameter passage, the spool I opening end of bottle cap shape is the relative formation bar gate type passage in interval with bottle cap shape spool II opening end, but be called variable diameter passage, spool III is the hollow cylindrical of a bottom lock, spool III seated connection cylindraceous is in spool I, moving valve is the cavity cover of a top seal, be installed in the spool II, the inwall of the outer wall of moving valve and spool II is set to sliding connection, the inwall of moving valve is set to be connected movingly with the outer wall cunning of spool III, between both ends of the spring difference fixed spool III and the moving valve, valve gap is connected the front portion of valve body.
The working principle of the utility model dynamic flow balance valve is: the pressure reduction before and after the equilibrium valve is during less than working pressure, because equaling work, the spring pressure of moving valve setting presses, so moving valve can not move, the flow through outer wall of spool II and the not variable diameter passage between the body cavity wall, through the mouth cylinder of the mouth cylinder of spool I and the spool II maximum variable latus rectum of the gate of relative formation at interval, flow is understood the increase of pressure difference and is increased again; Pressure reduction before and after the valve greater than range of working pressure in the time, pressure difference before and after the equilibrium valve acts on the moving valve, overcome length of spring compressed and try hard to recommend moving moving valve toward lower slider, moving valve blocks the part position of mouth cylinder with the gate of the mouth cylinder relative formation in interval of spool II of spool I, promptly regulate variable latus rectum size, thereby regulate the dynamic flow balance automatically with moving of moving valve.This dynamic flow balance adjustment is the flow rate calculation formula that meets " flow=unit cross-sectional area * flow velocity (hydraulic pressure) ".
The utlity model has following advantage: because this dynamic flow balance valve is provided with constant latus rectum and variable latus rectum, employing moving valve principle is dealt with the variation in pressure in the pipeline, promotes moving valve by pressure and changes the current latus rectum, to reach the flow dynamics balance.After tested, in its operating pressure differential scope, the precision of balanced flow is within 10%.
