Description
Technical field
The utility model refers to a kind of STEAM TRAP that is used for deriving the steam water of condensation especially about a kind of STEAM TRAP.
Background technique
The recovery of water of condensation is an engineering that systematicness is strong, need whole planning and targetedly technology and equipment realize the efficient operation of condensate return system.From the angle of energy-saving and emission-reduction, the quality good or not of drain valve is most important.Good drain valve need switch the worry of process pipelines flow process in the time of can exempting frequent the replacing, for long-term stability production brings guarantee, and bring the easy of maintenance, and need not loaded down with trivial details drain valve and follow the tracks of investigation or testing apparatus, need not to change spare part and kit, this will produce the good condition of creating for safety and stability, and lower working strength of workers.
And steam trap at present commonly used can be divided into three kinds of mechanical-type drain valves, heat static force type drain valve, heat power type drain valve usually, and these three kinds of drain valves ubiquity between usability and functional reliability is contradictory, though it is good all to possess the saturated water of condensation performance of discharging, but because of it has movable part, as lever, spool, owing to reasons such as wearing and tearing, foreign matter obstructions, cause mechanical failure easily.Specific as follows:
Be the density difference that utilizes water of condensation and steam in the mechanical-type drain valve,, make the float lifting drive flap and open or close, reach the block steam and drain water purpose by the water of condensation liquid level change.As: freedom half Ball float steam trap in the mechanical-type drain valve is a movable part by the ball bucket that one and half float-ball types are set, opening down, the ball bucket promptly is an open-shut device, is again Sealing.When device just started, air in the pipeline and low-temperature condensate entered in the drain valve through emission tube, and the bimetallic strip emptying element in the valve flicks the ball bucket, valve opening, and air and low-temperature condensate are discharged rapidly.In steam entered the ball bucket, the ball bucket produced to buoyancy, and the temperature in the valve raises simultaneously, bimetallic strip emptying component shrinkage, and ball is disclosed and is floated to valve port valve closing.Steam in the ball bucket becomes water of condensation, and ball bucket loss of buoyance sinks, valve opening, and water of condensation is discharged rapidly.When steam enters within the ball bucket again, valve is closed again, is interrupted and continuous operation.
The heat static force type drain valve is to utilize the temperature difference of steam and water of condensation to cause the modification of heat responsive element or expand drive valve core opening/shutting valve.As: the main action element of the bellows-type formula drain valve in the heat static force type drain valve is a metal bellows, in fill a kind of gasification temperature liquid lower than water saturation temperature, there have Opening valve temperature to be lower than 15 ℃ of saturation temperature and 30 ℃ two kinds to be selective.During device starting just, cryogenic condensation water appears in pipeline, and the liquid in the bellows is in condensing state, and valve is in the enable possition.When condensate temperature raises gradually, film closes the internal-filling liquid start vaporizer, and film closes internal pressure and rises, and diaphragm drives valve core and moves to closing direction, and before condensed water reached capacity temperature, drain valve began to close.Bellows plays the block steam and drain water effect with vapor (steam) temperature change control valve gate switch.
Heat power type drain valve be by steam and water of condensation by the time flow velocity and the different thermodynamic principle of Volume Changes, make valve block produce different pressure reduction up and down, drive the valve block switch valve. because of the operation power of thermodynamic trap derives from steam, so waste of steam is bigger. noise is arranged, valve block work is frequent, working life is short. as: a movable valve block is arranged in the thermodynamic trap in the heat power type drain valve, be position-sensing unit be again the action actuator. according to steam and water of condensation by the time flow velocity and the different thermodynamic principle of Volume Changes, make valve block produce different pressure reduction up and down, drive the valve block switch valve. leak vapour rate 3%, when device starts, the cooling water of condensation appears in pipeline, water of condensation is pushed valve block open by working pressure, discharging rapidly. when the water of condensation discharging finishes, steam discharges subsequently, because of steam bigger than the volume and the flow velocity of water of condensation, make valve block produce pressure reduction up and down, valve block is being closed rapidly under the suction of steam flow rate. when valve block is closed, valve block is subjected to two surface pressures, lifting surface area below the valve block is less than top lifting surface area, because of the source pressure of drain valve steam chest the inside in vapor pressure, so it is stressed above the valve block greater than following, valve block is closed tightly. and the steam cooling when drain valve steam chest the inside becomes water of condensation, the pressure of steam chest the inside disappears. and water of condensation is pushed valve block open by working pressure, water of condensation continues discharging again, periodic duty is interrupted draining.
As the above analysis, existing drain valve is to utilize the temperature difference, density difference between steam and the water of condensation to cause the modification of heat responsive element or expand to drive the valve core opening/shutting valve, because movable part, as lever, spool, owing to reasons such as wearing and tearing, foreign matter obstructions, cause mechanical failure easily.
