Abstract

The utility model relates to an auto-control liquid discharger of an under liquid discharging machine. The utility model is suitable for the liquid discharging which needs to be auto-controlled after the gas and liquid separating unit of natural gas drill site process, and the liquid discharger belongs to the manufacturing technical field of gas-liquid separation automatic control device. The auto-control liquid discharger of an under liquid discharging machine is an omni-mechanical automatic control gas-liquid discharger designed according to the philosophy of bob, handspike and choke seal in the liquid control technique, and the liquid discharging machine inverted is arranged at the bottom of the liquid discharging branch pipe. The utility model comprises three portions of a tube structure component, a bob leverage and a liquid discharging mechanism, solving the problem of that, an electric control device adopted in the present technique is easy to be ineffective and attacked by the gas exhausted from the oil gas drill site, and the utility model also has the advantages that process engineering and equipment is simple, and the liquid discharger can rapidly be repaired and be replaced parts at site.

Description

Underlying drainage mechanism automatic control liquid exhauster

Technical field: a kind of underlying drainage mechanism automatic control liquid exhauster, be applicable to the device that needs to control automatically discharge opeing on the technology of rock gas well site after the gas-liquid separator, be applicable to that also air compression station etc. has the industrial and mineral occasion that gas-liquid separation must the automatic control discharge opeing, belongs to gas-liquid separation and controls equipment manufacturing technology field automatically.

Background technique: the rock gas that comes out owing to underground mining in the gas production process is entrained with associated water; therefore the well site needs to carry out gas-liquid separation and to sedimentation water regular discharge with gas-liquid separator; Electric actuator or electricity-gas linkage are mainly adopted in the discharging of sedimentation water in the prior art; the shortcoming of prior art is: owing to relate generally to Electric actuator and electrical control in the technology that adopts; and contain the sour corrosion medium in the discharge liquid in oil gas well site; therefore; in running; Electric actuator and electric control equipment regular meeting lost efficacy because of corrosion; and the technology of prior art and equipment complexity, easy break-down and difficulty are given maintenance.

The model utility content:

The purpose of this utility model is according to float, lever and throttling sealing principle in the liquid control technique, designs a kind of fully-machinery type, the underlying drainage mechanism automatic control liquid exhauster of the automatic control gas-liquid discharging that is made of float, lever and underlying drainage mechanism.

Technological scheme: the purpose of this utility model is achieved in that this automatic control liquid exhauster is made up of cylinder part, float lever mechanism and drainage mechanism three parts, wherein cylinder part is made up of cylindrical shell, upper flange lid and bolt, nut, bearing, cylindrical shell and drain branch pipe form L shaped structure, the cylindrical shell arranged outside have upper inlet pipe, lower inlet pipe, liquid-discharging tube, on observe plug screw, down blow plug screw, the cylindrical shell internal upper part has been provided with the guiding gusset and has dredged the stream plate; Drainage mechanism is made of drain branch pipe, draining valve, valve seat, spool, and drainage mechanism is being inverted the bottom that is arranged on drain branch pipe; Lever one end and the float of float lever mechanism are hinged, and the fulcrum and the draining valve of the other end are hinged, the middle spool that connects; During the work of automatic control liquid exhauster, according to technological requirement, sedimentation water can be connected with upper inlet pipe or lower inlet pipe through Drainage pipe and enters in the cylindrical shell in the gas-liquid separator of well site, along with the liquid increase make float in the cylindrical shell under guiding gusset guiding to rising, and the drive lever moves upward, the spool that is arranged on the lever centre is lifted off a seat open the passage that liquid flows out, liquid is discharged through liquid-discharging tube, when liquid flows out in the cylindrical shell, liquid level descends, float is also sunk, and drive lever decline, spool is descended contact valve seat and the passage of closing liquid discharging; Last observation plug screw is used to check that liquid level or balance gas insert usefulness, and the down blow plug screw is used to discharge the impurity of sedimentation, at the cylindrical shell inner bottom part dilution that heating coil is used for heating of cold area or thick liquid is set.

The utility model has the advantages that: what the automatic control drainage mechanism adopted is the method for mechanical lever, does not have electric device, as long as material is taked etch-proof measure, just can not make mechanism's corrosion failure because of the acid medium in the gas-liquid.

Description of drawings:

Fig. 1 is a cross-sectional view of the present utility model.

Embodiment: figure below provides embodiment of the present utility model in conjunction with the accompanying drawings: this underlying drainage mechanism automatic control liquid exhauster is made up of cylinder part, float lever mechanism and drainage mechanism three parts, wherein cylinder part is made up of cylindrical shell 3, upper flange lid 10 and bolt 11, nut 12, bearing 1, cylindrical shell 3 forms L shaped structure with drain branch pipe 15, cylindrical shell 3 arranged outside have upper inlet pipe 9, lower inlet pipe 5, on observe plug screw 13, down blow plug screw 2, liquid-discharging tube 19 is arranged on the outlet end of drain branch pipe 15, and cylindrical shell 3 internal upper parts are provided with guiding gusset 6 and dredge stream plate 8; Drainage mechanism is falling to be arranged on the bottom of drain branch pipe 15, constitute by draining valve 18, valve seat 20, spool 16, spool 16 can be spherical, can be the conical surface, also can be the plane, valve seat 20 is inverted the bottom that is installed in drain branch pipe 15, by fixedly plug screw 21 is fixing; One end and the float 7 of the lever 14 of float lever mechanism are hinged, and the other end is that fulcrum 17 is connected with draining valve 18, and spool 16 is connected the centre and the valve seat 20 corresponding positions of lever 14; During the work of automatic control liquid exhauster, requirement according to fluid-discharge technology, the Drainage pipe of sedimentation water can be connected with upper inlet pipe 9 and enters in the cylindrical shell 3 in the gas-liquid separator of well site, also can be connected and enter in the cylindrical shell 3 with lower inlet pipe 5, along with the increase of amount of liquid in the cylindrical shell 3, float 7 rises under the guiding of guiding gusset 6 and drives lever 14 motions, and lever 14 drives spool 16 and upwards lifts off a seat 20, open the discharge passage of liquid, liquid is discharged through liquid-discharging tube 19; After the fluid removal, the liquid levels in the cylindrical shell 3 descend, and float 7 is sunk, and drive lever 14 and move downward, and lever 14 makes spool 16 contact and the discharge passage of closing liquid with valve seat 20 under the effect of the other end fulcrum 17 downwards; Last observation plug screw 13 is used to check liquid level, and the access port that also can be used as balance gas uses; Down blow plug screw 2 is used to discharge the impurity of sedimentation; Being arranged in this automatic control liquid exhauster cylindrical shell the hot coil 4 of bottom can heat to cylindrical shell when cold area uses, or heats and make thick liquid dilution in the cylindrical shell, so that discharging.
