Description
Technical field
The present invention relates to valve technology field, especially relate to the device that a kind of evaporative type cooling equipment supplements cooling water automatically.
Background technique
At present, evaporative type cooling equipment is widely used in every field.Evaporative type cooling equipment is applicable to cooled fluid and directly can not contacts with ambient air, has sufficient spray water source, and the occasion that source quality is less scaling.Closed cooling tower, is called for short and closes tower.Close tower and come from devaporizer, the form of this kind of cooling equipment is more, its common feature is at the outer spraying water of dividing wall type heat exchanger and forced ventilation, heat passes to the spraying water outside wall from the cooled fluid in dividing wall type heat exchanger through wall, air is passed to again by the forced convection of spraying water and air, and spraying water is to the heat transfer of air, the Exchange of apparent heat of the latent heat mainly evaporated by spraying water and spraying water and air forms.Due to cooled fluid in dividing wall type heat exchanger and between extraneous manufacturing equipment closed cycle flow, for being different from the general cooling tower that cooled fluid directly contacts with air, therefore have the title of " closing tower ".Close tower compared with air cooling device, close the latent heat of vaporization that tower make use of spraying water, so have the relatively less feature of heat transfer area, but spraying water can be brought to evaporate and scale problems simultaneously.And wall temperature is higher, evaporation and fouling more severe.Along with continuous evaporation and the loss of spraying water, water spray is more and more less, and the efficiency of evaporative type cooling equipment reduces gradually, at this moment, needs moisturizing in Sprayer Circulation system.Traditional water supplementing method is all adopt float valve, but float valve itself takes up space greatly, and the aim pursuing compact structure with evaporative type cooling equipment is wanted to carry on the back; Secondly, the working life of float valve is short, and subsequent maintenance cost is high.Chinese patent Authorization Notice No. CN86207045U, authorized announcement date on September 30th, 1987, the model utility that name is called " Automatic water valve ", disclosed a kind of recloser valve structure.It is by valve body, lower seat, floating drum and rubber tube composition, valve body there is a center hole, there is the hole of a straight-through lower seat center hole side, the cavity of one cross section in " convex " font is arranged at center hole bottom, cavity side has a logical outside dewatering orifice, and in cavity, also have the piston body of a band rubber case, lower seat has center hole, through also porose 12 and hole 7 of center hole, groove in lower seat and hole 12 are connected, floating drum connects with valve rod, and valve rod is inserted in lower seat center hole, valve rod is provided with hole 15, floating drum pin is positioned on lower seat, valve body and lower seat are by scyewed joint, valve body and lower seat and floating drum metal or plastics are made.Floating drum, under the effect of buoyancy of water with its gravity, can make valve rod move up and down, thus the piston in valve body is moved up and down, and determines the opening and closing of water valve.This model utility not only complex structure, manufacture cost is high, and switch water valve to be communicated with hole 12 or hole 7 by hole 15 and to decide, and installs and use is restricted.
Summary of the invention
In order to solve the technical problem that in prior art, evaporative type cooling equipment automatic water-replenishing device takes up space greatly, working life is short, maintenance cost is high, the invention provides a kind of compact structure, long service life, easy to maintenance, automatically can supplement the device of cooling water according to the height of water level electrodeless adjustment moisturizing speed.
Technological scheme of the present invention is: a kind of evaporative type cooling equipment automatic water-replenishing device, it comprises tubular earial drainage part, and earial drainage part upper end is connected with valve body, and valve body is provided with water supplement port, earial drainage part lower end is connected with the buoyancy bucket of cavity body structure, buoyancy bucket lower end is provided with water intake, is provided with drive lead screw in earial drainage part, and drive lead screw upper end is connected with spool, spool and water supplement port match, drive lead screw lower end is connected with buoyancy block, and buoyancy block and buoyancy bucket match, and earial drainage part sidewall is provided with discharge orifice.Spool stroke is short, long service life, reduces maintenance cost.The difference of water level height directly translates into the size of water supplement port switch, not only achieves automatic water supplement, and achieves the electrodeless adjustment to moisturizing speed.Compact structure, conserve space.
As preferably, water supplement port is cylindrical hole, and spool is stepped round platform, and spool upper end diameter is less than water supplement port diameter, and spool lower end diameter is greater than water supplement port diameter; Linear sealing is carried out to water supplement port in spool top, and spool bottom contacts with water supplement port end circular periphery, carries out face sealing.
As preferably, drive lead screw is connected with slide plate, and slide plate is plate-like, and slide plate surrounding and earial drainage part inner chamber match, and slide plate is provided with water port; Drive lead screw can only move up and down, and guarantees spool and water supplement port opening and closing reliable.
