Abstract
The utility model relates to a pressure-equalized continuous water discharge type steam drain valve, which is a water drainage device used in heat consuming equipment in a thermodynamic system. The utility model comprises a drain valve body, the inner part of the drain valve body is provided with a floating ball, and the bottom end of the drain valve body is provided with a non-moving pressure difference drain valve. The utility model has the advantages of automatic and continuous water discharge and drainage, pressure equalizing for water drainage, continuous discharge, etc.
Description
The utility model relates to the steam trap connection that uses with hot equipment in the thermodynamic system.It is a kind of continuous drainage formula Automatic steam trap Trap of all pressing.
At present, mostly use Automatic steam trap Trap to come block steam and drain water with hot equipment in the water heating system.Because existing all kinds of Automatic steam trap Traps cause more flash steam in bigger pressure drop and the waste pipe for being interrupted draining and drain opening through less, it is not smooth that hydrophobic in the waste pipe flowed, and can not pass at a distance.In addition,, act frequently, be easy to cause trap leaking, damage because the Automatic steam trap Trap operating conditions is relatively poor.Obturation often takes place in drain valve, spurts, lets out faults such as vapour, discharge capacity deficiency, and maintenance brings very big difficulty to drain valve, simultaneously, also causes bigger heat loss to thermodynamic system.
The purpose of this utility model is, a kind of continuous drainage formula Automatic steam trap Trap of all pressing is provided, make it have continuous blow-down automatically hydrophobic, make hydrophobicly can all press, advantage such as discharge continuously.
The utility model provides a kind of continuous drainage formula Automatic steam trap Trap of all pressing for finishing the foregoing invention purpose.Its technological scheme is: it has hydrophobic valve body, and ball float is installed in the hydrophobic valve body, and no dynamic pressure difference drain valve is installed in hydrophobic valve body bottom.The structure of no dynamic pressure difference drain valve is, offers water outlet collection chamber on valve seat, and the centre of valve seat is provided with spool, and spool adopts heavy caliber, offers the hole on the spool, and valve pocket is installed in the spool outside, offers the hole on the valve pocket.Spring is set in the spool.
The utility model is owing to adopt the aperture of the height control drain valve of ball float, and the height of float is again by hydrophobic amount decision, and the aperture that this just can reach hydrophobic amount control drain valve can make the utlity model has to reach the hydrophobic advantage of automatic continuous blow-down; Because the utility model has adopted the structure of no dynamic pressure difference drain valve, so, can produce less pressure drop, make hydrophobicly can all press, discharge continuously, the while can make and the utlity model has higher back pressure, can carry hydrophobic advantage at a distance.This reality is novel also to have an external power-free, no rotating component, no easily damaged parts, can avoid the advantage of keeping in repair for a long time.
Description of drawings, accompanying drawing 1 are structural representations of the present utility model; Accompanying drawing 2 is structure for amplifying schematic representation of no dynamic pressure difference drain valve 5 in the utility model accompanying drawing 1.The contrast accompanying drawing: embodiment is described further to the utility model: 1 is the hydrophobic inlet tube of the utility model when using among the figure, the 2nd, and blower line, the 3rd, hydrophobic valve body is installed ball floats 4 in the hydrophobic valve body 3, and no dynamic pressure difference drain valve 5 is installed in hydrophobic valve body 3 bottoms.The structure of no dynamic pressure difference drain valve 5 is, offers water outlet collection chamber 13 on valve seat 8, and the centre of valve seat 8 is provided with spool 10, spool 10 adopts heavy caliber, spool 10 inner upper/lower terminal water inlets have solved the pressure non-uniform phenomenon that unidirectional water inlet produces spool, to reach the purpose of eliminating the dynamic pressure difference.Offer hole 15 on the spool 10, valve pocket 9 is installed in spool 10 outsides, offers hole 16 on the valve pocket 9.On the spool 10 on perforate 15 and the valve pocket 9 perforate 16 produce less pressure drop with progressive the realization, spring 11 is set in the spool 10.When the utility model used, when the hydrophobic amount of steam increased, ball float 4 rose, and the spring 11 that does not at this moment have in the dynamic pressure difference drain valve 5 is mentioned spool 10, increases the drainage area of drain opening, thereby increases hydrophobic water displacement; When the hydrophobic amount of steam reduces, ball float 4 descends, spool 10 is descended, reduce the drainage area of drain opening, thereby reduce hydrophobic discharge capacity: when with the hydrophobic generation of hot equipment no steam out of service, ball float 4 drops to minimum point, will not have dynamic pressure difference drain valve 5 and closes fully, at this moment hydrophobic the stopping of steam discharged, to guarantee in drain valve certain liquid level being arranged.In addition, no dynamic pressure difference drain valve 5 is to change hydrophobic discharge capacity by the size that changes flow area, and the valve port footpath is bigger, pressure drop reduces in the time of can making hydrophobic passing through, the secondary steam that the hydrophobic generation of steam is less is convenient to remote conveying, also is not easy to produce simultaneously blocking phenomenon.6 is hydrophobic water outlet valves among the figure, the 7th, and intake pipe, the 12nd, it is stifled to discharge water, and the 14th, outlet pipe.
