Description of drawings
Fig. 1 is the structural representation of double-action drain valve of the present utility model.
Embodiment
See also Fig. 1, this double-action drain valve comprises: valve chest 20, water intake 21, water outlet 22, suction port 23, air outlet 24, upper floating ball 25 and upper floating ball bindiny mechanism 26;
Wherein, water intake 21, water outlet 22, suction port 23 and air outlet 24 all are arranged on the valve chest 20;
Upper floating ball 25 is positioned at valve chest 20 inside, and is connected with air outlet 24 with suction port 23 by upper floating ball bindiny mechanism 26, and this upper floating ball 25 can rise or descend with the liquid level of valve chest 20 inside around following ball float bindiny mechanism 26;
In valve chest 20 inside, this drain valve 26 also is connected with ball float 28 by following ball float bindiny mechanism 271, and following ball float 28 can rise or descend with the liquid level of valve chest 20 inside around following ball float bindiny mechanism 271.
Wherein, this upper floating ball 25 is positioned at the top of this time ball float 28, upper floating ball bindiny mechanism 26 has one and is used to control the upper floating ball screens mechanism (not shown) of upper floating ball 25 around the distance of 26 risings of upper floating ball bindiny mechanism or decline, because the control of this screens mechanism, extreme lower position and pipeline that this upper floating ball 25 is descended have one at interval, this pipeline of unlikely collision, and same control by this screens mechanism, extreme higher position and valve chest 20 internal surfaces that this upper floating ball 25 is risen have one at interval, unlikely collision valve chest 20.
Equally, following ball float bindiny mechanism 271 has a following ball float screens mechanism (not shown) that is used to control down distance that ball float 28 rises or descend, because the control of this time ball float screens mechanism, the lowest order that extreme higher position that following ball float 28 rises and upper floating ball 25 descend is equipped with one at interval, unlikely two balls bump against, extreme lower position and valve chest 20 internal surfaces that following ball float 28 descends have one at interval, and unlikely this time ball float collides this valve chest 20.
In addition, this valve chest 20, water intake 21, water outlet 22 all adopt carbon steel; This upper floating ball 25, upper floating ball bindiny mechanism 26, down ball float 28, down ball float bindiny mechanism 271, drain valve 27, suction port 23, give vent to anger 24 mouthfuls and all adopt stainless steel material.
Working principle with regard to this double-action drain valve describes below:
When the intake pressure of water intake 21 during greater than the discharge pressure of water outlet 22, following ball float 28 rises with liquid level, by this drain valve 27 unlatchings of ball float bindiny mechanism 271 drives down, water is normally discharged, when water of condensation reduces, liquid level descends, following ball float 28 is with the valve opening flow of liquid level lift adjustment drain valve 27, this moment, upper floating ball 25 was not owing to be subjected to the influence of liquid level, therefore, can not drive upper floating ball bindiny mechanism 26 suction port 23 is opened, at this moment, the water of condensation in this valve chest 20 does not need the power gas of suction port 23 that water of condensation is normally discharged.
(water outlet 22 is equipped with safety check during less than discharge pressure when the intake pressure of water intake 21, water can not flow backwards), following ball float 28 rises with liquid level, though this moment, drain valve 27 was opening states, water still can not be discharged by water outlet 22, this moment, upper floating ball 25 rose with liquid level, drive upper floating ball bindiny mechanism 26, air outlet 24 is closed, and suction port 23 is opened, and at this moment, power gas (as steam or air) enters into valve chest 20 inside from suction port 23, the pump internal pressure is raise, water of condensation is discharged.And this water intake 21 also is equipped with a safety check, and therefore, this water of condensation is discharged from this water outlet 22.
This scheme is by establishing drain valve 27 and following ball float 28 in valve chest 20, rise with the liquid level of valve chest 20 inside and to control the unlatching of drain valve 27, and draining, at this moment, upper floating ball 25 can not drive upper floating ball bindiny mechanism 26 owing to be not subjected to the influence of liquid level, and suction port 23 is opened, therefore, can not enter in the pump housing by dynamic gas yet; And when having only intake pressure when water intake 21 less than discharge pressure, under the situation that water can not be discharged by water outlet 22, upper floating ball 25 rises in liquid level, driving upper floating ball bindiny mechanism 26 opens suction port 23, power gas enters in the valve chest, utilizes the pressure of power gas, and water is discharged; Promptly regulate with drain valve 27 drainings or with the draining of power gas according to the intake pressure of valve chest 20 inside and discharge pressure extent.
The above only is the preferable possible embodiments of the utility model, and is non-so limit to claim of the present utility model, and the equivalent structure that all utilization the utility model specifications and graphic content are done changes, and all in like manner is contained in the utility model scope.
