Abstract

The invention aims to provide a gas-water separating valve, which is characterized by being partitioned into two gas chambers, wherein a first gas chamber (11) comprises a gas inlet (8) and a cylindrical floater (7); a second gas chamber (12) comprises a gas outlet (2), a decompressing valve (3), a filter core (4) and a hollow bolt (5); the first gas chamber (11) is connected with the second gas chamber (12); a ventilation hole is formed between the first gas chamber (11) and the second gas chamber (12), and a piston valve (6) is arranged; when oil gas of a slurry pond (10) enters the first gas chamber (11) from an oil gas collecting device (9) and the gas inlet (8), the piston valve (7) is in an open state, and gas passes through the gas outlet (2) after moisture is filtered; and when water or slurry enters the gas inlet (8), the cylindrical floater (7) is supported and is used for driving the piston valve (6) to be closed, so that water or slurry is prevented from entering the second gas chamber (12) and an oil gas analyzer (1).

Description

The gas-water separation valve

Technical field

The present invention relates to a kind of gas-water separation valve; Relate in particular to a kind of oil and gas gathering gas-water separation valve; This device can filter the moisture in the oil gas in the oil and gas gathering process; And can prevent effectively that sealing or mud are aspirated in the oil-feed gas analytical instrument, the invention belongs to petroleum geology well logging technical equipment field.

Background technology

To carry out the oil and gas gathering analysis to the drilling landwaste at any time in the oilfield drilling,, when liquid level raises, be easy to water or mud are aspirated in the analytical instrument with tracheae, cause instrument to stop up or damage because harvester is closer from the drilling fluid mud pit; Moisture is bigger in the oil gas of gathering in addition, needs often to change drier, influence the oil and gas gathering effect if change untimely meeting.。

Summary of the invention

The objective of the invention is to, the oil gas that makes collection through opening of piston valve smoothly through and carry out moisture filter, after water or mud got into first air chamber, piston valve was closed, anti-sealing or mud get in second air chamber and the oil gas analytical instrument.

To achieve these goals, the present invention reaches through following measure: the gas-water separation valve, and it comprises first air chamber and second air chamber, and the cylinder float is housed in first air chamber, its lower end is an air inlet; Second air chamber upper end be venthole and relief valve, with the fixing filter core of hollow bolt, is provided with piston valve between first air chamber and second air chamber below the gas outlet.

The present invention can produce following good effect:

One, prevent effectively in the oil and gas gathering that through adopting cylinder float and piston valve, having solved water or mud are aspirated the into problem of analytical instrument, after water or mud were aspirated into first air chamber, the cylinder float can rise closed piston valve; Under the situation that does not have pump up water or mud, piston valve is in open mode, can make the oil gas of collection pass through piston valve smoothly;

Two, second air chamber is equipped with filter core, can filter moisture in the oil gas, can save the use of drier, and the moisture after the filtration can flow out through piston valve and air inlet voluntarily, without artificial drainage;

Three, be provided with relief valve, piston valve is closed when pump up water or mud, and second air chamber forms negative pressure, after turning on relief valve, can open piston valve easily;

Four, to be transparent material made for first air chamber and the second air chamber shell, is convenient to observe gas-water separation valve inner case.

Description of drawings:

Fig. 1 is the structural representation of first embodiment of the present invention.

The specific embodiment:

Below in conjunction with accompanying drawing preferred forms of the present invention is elaborated:

Embodiment (referring to Fig. 1): a kind of gas-water separation valve; It comprises first air chamber 11; First air chamber, 11 lower ends are in air inlet 8, the first air chambers 11 cylinder float 7, the first air chambers 11 to be housed and second air chamber 12 interconnects and be equipped with piston valve 6; Second air chamber, 2 set inside filter cores 4 are also fixing with hollow bolt 5, and its upper end is gas outlet 2 and relief valve 3.

Concrete operation instruction:

Start oil gas analytical instrument 1; Air pump begins suction and gathers oil gas; The oil gas that mud Buffer Pool 10 is separated out gets into second air chamber 12 through the piston valve 6 of oil and gas gathering device 9, air inlet 8, cylinder float 7, open mode successively, and the oil gas analysis was carried out with oil gas analytical instrument 1 in entering gas outlet 2 after filter core 4 carried out moisture filter; When mud Buffer Pool 10 liquid levels change; Cause water or mud to get into oil and gas gathering device 9; And after getting into first air chamber 11 through tracheae; Cylinder float 7 rises and promotes piston valve 6 and cuts out, and seals the through hole between first air chamber 11 and second air chamber 12, thereby effectively avoids water or mud to get into second air chamber 12 and oil gas analytical instrument 1; After turning on relief valve 3, can discharge the negative pressure in second air chamber 12, make piston valve 6 smooth opening.

Claims

1. gas-water separation valve, it comprises first air chamber and second air chamber, it is characterized in that; First air chamber comprises air inlet, cylinder float; Second air chamber comprises hollow bolt, filter core, relief valve, gas outlet, between first air chamber and second air chamber passage is arranged, and is provided with piston valve in it; It has gas through the time piston valve be open mode, gas gets into the oil gas analytical instrument through the gas outlet behind filter element filtering moisture; After water or mud got into first air chamber, piston held up through the cylinder float and closes passage, and anti-sealing or mud get into second air chamber and oil gas analytical instrument.

2. according to the said gas-water separation valve of claim 1; It is characterized in that; Said cylinder buoy upper is a column type hollow seal body, and the bottom is the open-type cylinder, and its base is a laciniation; Be convenient to be advanced on the oil gas first air chamber, also be convenient to the water droplet of oil gas after second air chamber filters and flow out through air inlet.

3. according to the said gas-water separation valve of claim 1, it is characterized in that said first air chamber is connected with second air chamber, be transparent material and make, convenient operating position of observing the gas-water separation valve at any time.
