Technical field
The utility model relates to a kind of device of automatic drain in storage of high pressure air liquid and the draining system, especially adapt to pressure height in oil and gas industry, and the pressure surge scope is big, contains the automatic drain valve of a kind of high-pressure large-displacement that uses under the big situation of amount of liquid.
Background technique
At present, automatic draining device in existing the application is to utilize ball float as power source, utilize lever principle to amplify ball float suffered buoyancy in liquid, suffered buoyancy of ball float and the acting in conjunction of ball float self gravitation realize the unlatching and the sealing of pumping equipment, and sealed mouth and hydrophobic spool are fitted in the valve body in ball float and the pumping equipment.Its structure exists defective mainly to show as: the first, ball float need overcome the difference force of ball float self gravitation and the formation of container inside and outside differential pressure, because difference force is relevant with the aperture of containment system pressure and discharge opeing, difference force is directly proportional with system pressure and liquid port area, big or excursion is bigger when system pressure, when needing lifting rate big, need corresponding the ball float volume be increased, thereby the whole valve body volume also needs to increase; Simultaneously, bigger pressure reduction is arranged inside and outside the ball float, the ball float easy deformation is damaged, thereby ineffective; The second, existing pumping equipment can only be limited to the use of pumping equipment in certain pressure range or the specified lifting rate.
In actual the use, pressure and the excursion of liquid measure in the process of producing in a lot of hydrops devices are very big, and this just requires pumping equipment that bigger adaptive capacity must be arranged, and require bigger pressure surge scope and bigger lifting rate fluctuation.Three, hydrophobic spool sealed mouth and valve nozzle open and close are frequent in existing the application, wearing and tearing easily.Because pumping equipment sealed mouth and hydrophobic valve nozzle are easily damaged parts.Installation and maintenance need will be whole device just can finish after dismembering, the amount of labour is big, and needs the several people to coordinate one or two hour ability simultaneously to change and finish.These problems occur in storage of actual high-voltage gas-liquid and drainage system application in a large number, influence national product.
The model utility content
The purpose of this utility model is in order to adapt in the existing application system pressure surge scope big, the requirement that lifting rate fluctuating demand scope is big, overcome the phenomenon that existing ball float damages easily, overcome existing easily damaged parts and change shortcomings such as complex procedures, the utility model provides a kind of high-pressure large-displacement automatic drain valve, can not only automatically the liquid in the container be discharged fast, and this device can adapt to high pressure, big discharge capacity, and pressure and the big situation of flow oscillation scope, the influence that is not stressed of the power source of this device simultaneously can not damage distortion because of variation in pressure, and easily damaged parts such as sealing surface can be provided for simple replacement of fast by single.
The technological scheme that the utility model proposes realizes as follows:
The automatic drain valve of a kind of high-pressure large-displacement, comprise the upper cylinder and the lower cylinder body that connect by flange, upper cylinder and lower cylinder body are equipped with upper cover and lower seal head respectively, it is characterized in that: the hollow position in the joint of upper cylinder and lower cylinder body is provided with the floating drum of upper end closed lower end opening, and described floating drum is a metal cylinder.
The lower end of described floating drum is fixedly connected with the lever with the floating drum associated movement, and the other end of lever extends in the connecting tube of lower cylinder body outside connection.
The lever end that is positioned at connecting tube is installed on the connecting tube inwall by hinge, and lever end is fixed with sealed mouth, also can be connected lever end by other mechanisms with the hinging manner identical function.
The connecting tube side is connected with liquid-discharging tube, is provided with between connecting tube and the liquid-discharging tube by fixing chuck plate and the fixing hydrophobic spool corresponding with sealed mouth of pressing plate.
Connecting tube is communicated with liquid-discharging tube in the side by taking over.
The upper cylinder side is provided with the inlet tube and the mouth of pipe of symmetry, is fitted with the tubular type filter screen in the inlet tube and the mouth of pipe.
Upper cover is provided with muffler; The lower seal head bottom is provided with scum pipe.
Connecting tube and adapter also can be respectively equipped with the flanged easy-to-dismount mouth of pipe, can dismantle during convenient for maintaining.
Working principle of the present utility model is as follows:
When the utility model installs and uses, at first by muffler to the slow pressurising of cylindrical shell,, pressurized gas that can the storage relevant pressure in the floating drum; Behind the inlet tube of the interior equipped tubular type filter screen of upper cylinder, enter cylindrical shell when system liquid gas fluid-mixing then, liquid-immersed floating drum, floating drum forms the device of a hollow, and this moment, system pressure equated with the floating drum pressure inside by liquid.When liquid gas mixed flow more after a little while, during less than the gravity of floating drum gravity and lever segment, floating drum drives lever and moves down liquid buoyancy, moves on the sealed mouth of lever end in the cylindrical shell outer connecting pipe and hydrophobic spool closure for the active force of floating drum; Along with the increase of liquid, when liquid buoyancy for the active force of floating drum during greater than the gravity of floating drum gravity and lever segment, floating drum drives on the lever and moves, the sealed mouth that drives lever end moves down, sealed mouth separates with hydrophobic spool, realizes discharge opeing; After the discharge opeing, liquid level drops to liquid buoyancy for the active force of floating drum during again less than the gravity of floating drum gravity and lever segment, and floating drum drives lever and moves down, and drives to move on the sealed mouth of lever end and hydrophobic spool closure again, the work that so moves in circles realizes that big discharge capacity is hydrophobic automatically.
The beneficial effects of the utility model are as follows:
The utility model can be discharged the big quantity of fluid in the container automatically fast, floating drum by the hollow open that is provided with is as power source, such spar structures has been avoided the destruction problem that cylinder internal pressure is too high or pressure range causes more greatly, reduce equipment failure rate greatly, can overcome the problem that the ball float high pressure destroys, adapt to high pressure, in pressure and the big situation of flow oscillation scope, the influence that the power source of this device also is not stressed can not damage distortion because of variation in pressure; Be assemblied in outside the cylindrical shell by sealed mouth and hydrophobic spool then, be convenient to remove and install, can change easily damaged partss such as sealing surface fast simply discharge opeing, overcome problem difficult in maintenance, improve the installation quality of pumping equipment, reduced the labor intensity of installation and maintenance, raise labour efficiency.
