Abstract
The utility model discloses a natural gas drain valve. An upper tube body provided with a concave buildup-welded flanged water inlet pipe is butted with a lower tube body provided with a water discharging and connecting pipe 1 through a flange, a flange gasket and an external hexagonal bolt, and an upper elliptical head is connected at the upper end of the upper tube body; a lower elliptical headis connected at the lower end of the upper tube body and installed on a base seat with a flange piece, one end of an elbow blow-off pipe is connected with the bottom of the lower elliptical head, andthe other end is led out of the side of the base seat; a baffle plate is transversely installed below the water inlet pipe on the inner wall of the upper tube body, a ball float component is installedin the lower tube body and connected with a sealing component installed on the water discharging and connecting pipe 1 via a cotter pin, a pin and a flat washer through a lever. The natural gas drainvalve is suitable to be installed and used in a gathering, storage and transportation system of a natural gas mine to realize gas-water separation and automatic discharge of sedimentary water (liquid) in the natural gas storage tank in the natural gas mine without natural gas leakage, and has the optimal energy saving and environment protecting effects.
Description
Technical field
The utility model relate to a kind of in the seal container of natural gas-storing the device of separate discharge connate water, be specifically related to a kind of rock gas drain valve.
Background technique
In the rock gas mine manufacturing operation process of petrochemical industry department, when gathering rock gas, understanding some underground water is accompanied by rock gas and erupts out in the lump and enter in natural gas line and the storage tank system, particularly in natural gas storage tank, can deposit a certain amount of moisture content, for quality grade that guarantees rock gas and the accumulating effectiveness that improves existing pipeline and gas holder system, should the connate water in the natural gas storage tank be drained as far as possible.For this reason, in the manufacturing operation of rock gas mine, be provided with the draining work post specially, by the connate water in the regularly responsible discharging storage tank of special messenger, but, because the artificial drainage operation is subjected to all multifactor influences, be difficult to accurately grasp, be difficult to accomplish just the connate water in the gas holder is just drained, just say at present, when artificial drainage, a large amount of rock gases are usually arranged along with discharge water together leaks out, this not only causes the waste and the environmental pollution of natural gas resource, also can initiation fire even explosive accident when serious, be the factor that is absolutely unsafe in manufacturing operation of current rock gas mine and the storage and transportation process.Recently, though the natural gas storage tank that has has been installed " moisture trap " device, but this device still needs the special messenger to operate, and drainage effect neither be very desirable, rock gas drain valve ball float commonly used is little, and poor sensitivity can't realize evenly linear continuous hydrophobic function of natural-gas, and discharge capacity is less, and sealing surface weares and teares easily, corrodes.
The model utility content:
The utility model is a kind of special messenger's of the need not operation that proposes on the basis of existing technology, and the automatic hydrophobic choke of energy, non-consumes energy can drain the connate water in the gas holder automatically and guarantee that rock gas does not have the rock gas drain valve of a bit leakage.
Its technological scheme is: a kind of rock gas drain valve, the lower cylinder body and the upper cylinder that comprise butt joint, upper end, upper cylinder side is equipped with intake pipe, lower end, lower cylinder body side is equipped with drainage connecting pipe I, below upper cylinder inwall intake pipe, be horizontally installed with baffle plate, in the cylindrical shell of baffle plate below the ball float assembly is installed, the ball float assembly is connected by lever with drainage connecting pipe I, it is characterized in that also comprising that a bottom is equipped with the base of base flange sheet, the fixedly connected ellipse head once in lower cylinder body lower end surface, and be fixedly placed on the base.One elbow drain pipe, one end connects ellipse head bottom down, and the other end is drawn by the base side.Lower cylinder body docks with upper cylinder lower end surface convex flange by its upper-end surface female flange, is lined with flange gasket between flange, and flange is by the outer-hexagonal bolton.The one last ellipse head that pressure gauge stand and pressure gauge, lifting bolt and rings seat, connection block are housed is fixedlyed connected with the upper cylinder upper-end surface.One end of lever is connected with ball float assembly lower end by cotter pin, bearing pin, plain washer, and the other end is connected with drainage connecting pipe I by black box.Drainage connecting pipe I outer end connects drainage connecting pipe II, and the intake pipe outer end connects concave surface built-up welding flange.Hydrophobic valve interior wall is through preservative treatment.
The drain valve internal structure adopts the big ball float of stainless steel.
The sealing surface of drain valve adopts hard alloy overlay welding.
This equipment is automatically worked continuously, and just row of water is arranged, and anhydrously closes connate water (liquid) emission index 100% automatically.Choke is tight, and no rock gas is revealed, and leakage rate is zero.Can the automatic sedimentation dirt, carry out periodical blowdown, stain resistance is strong, non-obstruction phenomenon.Equipment internals material is an all steel, and valve interior wall is through preservative treatment, long service life.Easy for installation, need not debugging, operate steadily, noise free, safe and reliable.The drain valve internal structure adopts big ball float, can increase discharge capacity, increases to 12T/h (same bore) by original 8T (10T)/h, and discharge capacity is evenly linear.Sealing surface adopts hard alloy overlay welding simultaneously, and is wear-resisting, and anti-steam flush is corrosion-resistant, long service life.Adopt arc top cover, outward appearance is more attractive in appearance.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The utility model is a kind of natural gas steam trap; , ( 1 ) ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 ) ( 7 ) ( 8 ) ( 9 ) ( 10 ) ( 11 ) ( 12 ) ( 13 ) ( 14 ) ( 15 ) ( 16 ) Y-60 ( 0-16MPa ( 17 ) ( 18 ) ( 19 ) ( 20 ) ( 21 ) ( 22 ) ( 23 ) ( 24 ) I ( 25 ) II ( 26 ) 。 In operation process, at first intake pipe (14) is connected in the waste pipe of the moisture trap of rock gas gas holder, at this moment connate water enters upper cylinder (12) through intake pipe (14), the rock gas of following connate water together to enter upper cylinder (12) is closed in the top of upper cylinder (12), at this moment ball float (11) is subjected to buoyancy of water bigger, ball float (11) vertically rises, pull lever is opened drainage connecting pipe (25) draining, decline along with water level, the buoyancy of ball float (11) reduces gradually, ball float (11) vertically descends, promote lever and close drainage connecting pipe (25), rock gas can be closed closely, prevent natural gas leaking, in the time of in connate water enters upper cylinder (12) once more, the rock gas gas that tightly is closed in the upper cylinder 12 is replaced back in the storage tank, so repeatedly, utilize gas, the density difference of aqueous medium is poor to the buoyancy that ball float 11 forms, pulling drainage connecting pipe (25) is opened or is closed during ball float 11 oscilaltions, reach the connate water in the gas holder is all drained, can thoroughly stop the purpose of natural gas leaking again.
