Abstract

The utility model discloses a gas control liquid level alarm comprising a floating drum, a travel staff, an air chamber shell body, an upper air chamber communication pipe, a lower air chamber communication pipe, an upper valve seat, a lower valve seat, an upper air chamber pipeline, a lower air chamber pipeline, an upper touch board, a lower touch board, a main air chamber, an upper air chamber, a lower air chamber and an air horn, which is characterized in that: the upper and lower valve seats are respectively welded on the upper and lower sections on the external wall of the air chamber; the floating drum is connected to the travel staff via a bolt; the upper and lower touch boards are fixed on the travel staff; a high and lower level alarm valves are arranged on the upper and lower valve seats; the upper and lower air chamber pipelines connect the upper and lower air chambers together with the high and lower level alarm valves. When the alarm is arranged on the tank and the liquid level of slurry rises, the floating drum will drive the travel staff to move upwards and downwards, the upper and lower touch boards prop open the high and lower level alarming valve and the air horn blows to forecast possible kick, blowout or circulation loss. With such a structure, the utility model ensures accurate, timely and effective forecast result and greatly reduces omitted and mistaken report, effectively enhances the safety in well site operation. Therefore, with unmanned supervision, the utility model has the advantages of simple structure, low cost, reliable performance, convenient portability and simple operation.

Description

The gas control liquid level alarm

Technical field:

The utility model relates to a kind of in petroleum drilling, workover treatment, as the gas control liquid level alarm of accidents such as prevention, forecast down-hole blowout, leakage.

Background technology:

Because it is sudden that blowout, leakage have, and need do long-time, continual monitoring to mud liquid level variation situation.Before blowout takes place or during the leakage of down-hole, the mud liquid level can produce rapid rising or decline because of well kick, leakage, and when situations such as former mud liquid level ANOMALOUS VARIATIONS took place, the mud liquid level variation was to be shown by scale, estimated supervision by operating personnel.Because careless omission, the paralysis of work can not guarantee the timely and effective of the work of monitoring, and have potential safety hazard.Need to arrange the special messenger to monitor.

Summary of the invention:

The purpose of this utility model provides a kind of use, carries more easily, and simple in structure, dependable performance utilizes siren to report to the police, need not special messenger monitoring, the forecast result timely and effectively, gas circuit control meets well site fire protection requirement, the control liquid level alarm of pressurized air convenient sources.

For achieving the above object, gas control liquid level alarm of the present utility model is mainly by floating drum, walk scale, gas source connector, gas chamber shell, main gas tank, the source of the gas valve, last lower chamber communicating pipe, upper valve base, upper chamber, air horn, the upper chamber pipeline, the scale orienting sleeve, the full level alarm valve, last touch panel, following touch panel, the low alarm valve, lower valve base, the lower chamber pipeline, lower chamber, structures such as separate layer are formed, upper valve base, lower valve base is welded on respectively on the gas chamber shell outer wall, on the hypomere, upper chamber is communicated with by last lower chamber communicating pipe with lower chamber, be weldingly fixed on last lower chamber communicating pipe in the gas chamber shell on, lower chamber separate layer stage casing.Gas chamber shell is a welded structure, main gas tank and upper and lower air chamber separate layer adopt welded structure, gas perverse be connected gas chamber shell upper end by joint screw thread, the scale orienting sleeve is welded on the upper and lower valve seat, floating drum is connected by bolt with walk scale, upper and lower touch panel utilization is bolted on the walk scale, high and low position alarm valve utilizes screw buckle to be connected on the upper and lower valve seat, upper and lower air chamber pipeline adopts thread connecting mode that upper and lower respectively air chamber is linked together with high and low alarm valve, and gas chamber shell is connected on the tank skin by bolt.

After adopting such structure, by using in the well site, forecast is accurate and effective as a result, and that reduces human factor greatly and produced fails to report, misrepresents deliberately, and effectively improves wellsite operation safety.Have gas circuit control and meet the well site fire protection requirement, the pressurized air convenient sources utilizes siren to report to the police, and need not special messenger's monitoring, and the result of accidents such as forecast down-hole blowout, leakage is timely and effective, simple in structure, dependable performance.Advantages such as cost is low, and is easy to carry, easy and simple to handle.

Description of drawings:

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the front elevation of gas control liquid level alarm of the present utility model.

Fig. 2 is the vertical view of gas control liquid level alarm of the present utility model.

Fig. 3 is the left view of gas control liquid level alarm of the present utility model.

Fig. 4 is the right view of gas control liquid level alarm of the present utility model.

Fig. 5 is the fundamental diagram of gas control liquid level alarm of the present utility model.

Among the figure 1, floating drum 2, walk scale 3, gas source connector 4, source of the gas valve 5, gas chamber shell 6, main gas tank 7, go up lower chamber communicating pipe 8, upper valve base 9, upper chamber 10, air horn 11, upper chamber pipeline 12, scale orienting sleeve 13, full level alarm valve 14, go up touch panel 15, touch panel 16, low alarm valve 17, upper valve base 18, lower chamber pipeline 19, lower chamber 20, full level alarm liquid level 21, operate as normal liquid level 22, low alarm liquid level 23, separate layer down.

Embodiment:

Shown in Fig. 1 to Fig. 5, liquid level alarm is behind installation in position on the tank body, the well site staff, warning height according to rising of mud liquid level and decline, the position of touch panel 14, following touch panel 15 and floating drum 1 and full level alarm valve 13, low alarm valve 16 in the adjustment, and will go up touch panel 14, down touch panel 15 is fixed on the walk scale 2, after connecting source of the gas, just be full of pressurized air in main gas tank 6 and upper valve base 8, the lower valve base 17, when the mud liquid level raise or descend, floating drum 1 drove walk scale 2 and moves up and down.When liquid level surpasses full level alarm liquid level 20, last touch panel 14 on the walk scale 2 will back down full level alarm valve 13, pressurized air in the upper valve base 8 arrive upper chambers 9 by upper chamber pipeline 11, air horn 10 warning of will blowing a trumpet, and blowout might take place in indication; When the mud liquid level drops to when being lower than low alarm liquid level 22, following touch panel 15 on the walk scale 2 will back down low alarm valve 16, pressurized air in the lower valve base 17 arrive lower chambers 19 by lower chamber pipeline 18, and air horn 10 warning of will blowing a trumpet is indicating and might advance leakage.In petroleum drilling, workover treatment, mud circulation jar liquid surface height is metastable under the situation of operate as normal liquid level 21, last touch panel 14 and following touch panel 15 on the walk scale can not back down full level alarm valve 13 and low alarm valve 16, perverse 10 warnings of just can not blowing a trumpet of gas are indicating the no abnormal variation of mud liquid level.Therefore, in time understand the ANOMALOUS VARIATIONS of mud liquid level, significant to accidents such as prevention, forecast down-hole well kick, blowout, leakages.
