Abstract
The utility model discloses a free type floating ball drain valve used for discharging condensate water. According to the free type floating ball drain valve used for discharging the condensate water, a valve body comprises a low-pressure ventilation channel and a condensate water discharging channel. When the valve works, low-pressure air flow passes through the low-pressure ventilation channel continuously, a low-pressure area is formed in an outlet of the valve so that air sealing of air and the condensate water in the condensate water discharging channel in the valve body can be achieved, the temperature and pressure of air in the valve body are increased when the level of the condensate water rises, an automatic air exhausting device which is controlled by two metal pieces is started, and noncondensing air in the valve body is exhausted; when buoyancy force borne by a buoy in the valve body is larger than the external air sealing pressure, the buoy is separated from a valve clack, and the condensate water is discharged. The drain valve has the advantages that the structure is simple, a good drainage effect and a good sealing effect are achieved by means of effective utilization of differential pressure, requirements for the manufacturing technology of a floating ball are not high, equipment cost is greatly reduced, the valve is resistant to water attack and is not provided with parts easy to damage, maintenance cost is low, and the service life is long.
Description
Technical field
The utility model relates to drain valve technical field, is specifically related to a kind of drain valve structure for condensed water elimination.
Background technique
Free style floating ball hydrophobic water valve is simple in structure, inside only has the stainless steel hollow float of a fine gtinding, be float and open-shut device, utilize the density difference principle of water of condensation and steam, stainless steel hollow float is placed on without restrictions to the valve inner of drain valve, thus when design using stainless steel hollow float itself as the flap that completes on-off action, ball float can freely rise or decline, thereby play the effect of flap, realize open and close valve events.Ball float is with the material of different-thickness, to make upper and lower two hemisphere to be welded.So upper and lower hemispheres can not be shifted when generally, ball float floats.
When equipment has just started work, air in pipeline is discharged through automatic-discharging device of air, low-temperature condensate enters in drain valve, and the liquid level of water of condensation rises, and ball float rises, valve opening, water of condensation is discharged rapidly, the very fast access arrangement of steam, and equipment heats up rapidly, the temperature sensing liquid of automatic-discharging device of air expands, and automatic-discharging device of air is closed.Drain valve starts normal operation, and ball float is with the lifting of water of condensation liquid level, block steam and drain water.The valve seat of loose float trap always, below liquid level, forms water seal, without steam leakage, and good energy-conserving effect.Minimum working pressure power 0.01Mpa, is not subject to the impact of temperature and working pressure fluctuation within from 0.01Mpa to maximum working (operation) pressure (MWP) scope, continuous drainage.Can arrange saturation temperature water of condensation, Minimum subcooled temperature is 0 ℃, and water not in heating plant, can make heating plant reach best heat exchange efficiency.Rate of back pressure is greater than 85%, is one of optimal drain valve of production technology heating plant.
But this drain valve has following vital wound, affected being widely used of it: ball float is an airtight hollow spheres, not water-fast hitting, and soldered be easy to leak under High Temperature High Pressure and corrosion, so that moves malfunctioningly, and ball be difficult for to be repaired again.Once there be impact steam flow, cause ball float to roll, water seal is malfunctioning, causes the leakage of internal gas.
Model utility content
The technical problems to be solved in the utility model is for the existing technical problem of existing free style floating ball hydrophobic water valve technology, provides a kind of simple in structure, and without quick-wear part, cost is low, the drain valve that hydrophobic effect is strong.
The technical solution of the utility model:
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of free style floating ball hydrophobic water valve for condensed water elimination mainly comprises a kind of low pressure venting channels and condensed water elimination passage, utilize the flowing of low-pressure air of venting channels, in condensed water elimination outlet port, form low pressure, contribute to condensed water discharge completely continuously.Pressure in drain valve condensed water housing is during higher than outlet pressure, and ball float and flap are airtight, forms sealing gland, prevents that internal gas from revealing.
As preferably, in condensation water channel, the Stainless Steel Ball of free floating is 304# stainless steel material.
As preferably, in condensation water channel, automatic exhaust valve adopts bimetallic strip as control unit.
Advantage of the present utility model:
The utility model manufacturing process is simple, utilizes the principle of sealing gland, can effectively solve the problem of ball float displacement, greatly reduces the fabricating cost of ball float, and water resistant is hit, and low maintenance has extended working life of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-low pressure breather line suction port, 2-condensed water water intake, 3-ball float, 4-flap, 5 drain valve outlets, 6-automatic exhaust valve.
Embodiment
A kind of mode of execution of the utility model as shown in Figure 1.
During valve working, low-pressure air enters in drain valve breather line from low pressure breather line suction port 1, and flow out from drain valve outlet 5, the drain valve outlet 5 that is flowing in of low-pressure air forms low pressure area, pressure reduction closes ball float 3 and flap 4, automatic exhaust valve 6 closes, and completes the sealing gland to valve inner air and condensed water.Condensed water flows to condensation water collection discharge passage in drain valve by condensed water water intake 2, rising along with liquid level in passage, the temperature sensing metal support of automatic exhaust valve 6 is experienced pressure and temperature effect in valve body, there is deformation, automatic exhaust valve 6 is opened, discharge incondensable gas in valve body, reduce valve body internal pressure.When ball float 3 is subject to condensation buoyancy of water, be greater than extraneous sealing gland pressure, ball float 3 is opened with flap 4, and condensed water, under the drainage of breather line, exports 5 by drain valve, completes the discharge of condensed water.Liquid level reduction along with condensed water.The buoyancy that ball float is received is during lower than the pressure of sealing gland, and ball float 3 is closed with flap 4, reaches the effect of draining choke.
In low pressure venting channels, air-flow can be process seal gas, also can adopt the utilization of high-tension apparatus secondary exhaust gas.As preferably, adopt low-pressure industrial blanket gas.
The utility model has overcome not water-fast hitting of traditional floating ball hydrophobic water valve, and the easy to failure and technical problem that causes internal gas to leak is utilized the principle of sealing gland, efficient solution the problem of ball float displacement certainly, greatly reduce the fabricating cost of ball float, water resistant is hit, low maintenance, has extended working life of equipment.
Above-described the utility model mode of execution, does not form the restriction to the utility model protection domain.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
