Pressure equalizer is the critical component that the present invention is able to implementation success.According to the invention needs, pressure equalizer must have the function of block steam and drain water; Has the function that pressure reduction is regulated equal pressure water; Have the large characteristics of flow adjustment range; Has the advantage of not leaking with reliable operation.
The block steam and drain water function of pressure equalizer is determined by structure.Because the osculum of control valve is large more than the valve opening of drain valve in the pressure equalizer, so pressure equalizer can not only satisfy the block steam and drain water of the hot equipment of little usefulness, more be applicable to large many in parallel uses that need not with the block steam and drain water of hot equipment.
The pressure reduction of pressure equalizer is regulated equal pressure water function, is by changing the seat of adjusting screw(rod) on the strip plate of control valve, make it act on spring holder and lower spring, realizing with the thrust between change spool and the valve seat outlet.The successful Application of pressure equalizer, the equal pressure condition that becomes to be as the criterion when the condensate water that different pressures is generated with hot equipment enters the condensate water manifold trunk for realizing centralized drainage, all reclaims condensate water, has created condition for the anisobaric system realizes the closed operation of common network.
For pressure equalizer being had do not leak the advantage with reliable operation, upper design has special-purpose cylindricality float within it, and is furnished with weight in inside, makes its floating just when water level reach a certain height, and stops steam leakage thereby formed a large thickness water seal.The functional reliability of pressure equalizer is then guaranteed by the dedicated regulation valve that designs below float.Be provided with upper spring between sleeve and the valve seat, under the acting in conjunction of the deadweight of buoyancy and float and upper spring expansion force, sleeve is made up and down axially-movable, the aperture of osculum on the control valve seat along the external cylindrical surface of valve seat with the working method that suspends.Because sleeve is in suspended pattern work, whole parts of control valve all exist without the impact wear problem, and its osculum is large more than the valve opening of drain valve, and the possibility of obstruction is extremely small, thereby makes pressure equalizer reach the requirement of not leaking with reliable operation.
Because pressure equalizer has the large advantage of flow adjustment range, every must be disposed a drain valve with hot equipment before, even many drain valve parallel operations are unnecessary.When in the system during with the equating or substantially equate with steam pressure of hot equipment, can not consider with what of hot number of devices, its condensate water is exported connect a pressure equalizer after parallel connection and get final product.Thereby pressure equalizer greatly reduces than the usage quantity of drain valve, and system consists of succinct.
The above-mentioned functions that pressure equalizer has and advantage are for successfully realization of the present invention provides technical support and assurance.
The present invention has obvious advantage compared with the prior art: cancelled the power conveying machineries such as the drain valve that uses in the system and electric pump, system consists of succinct, and maintenance work greatly reduces; Thoroughly solved because being unfavorable for the problem of system's closure after the drain valve inefficacy, realized the closed operation of anisobaric system common network truly; Steam latent heat all discharges in hot equipment, nothing is leaked, and condensate water and sensible heat thereof all effectively reclaim, and system is more energy-conservation; The minimizing of energy resource consumption reduces the discharging of greenhouse gases, is conducive to the improvement of environment; The special equipment such as pressure equalizer and adjusting device is without consumable accessory, and system's reliability of operation is high, and useful life is long.
