The liquid indicator comprises a buoy, a permanent magnet float and a flap indicator, the buoy is provided with an upper connecting flange and a lower connecting flange communicated with a container, a filter screen is mounted in the buoy at the lower end of the lower connecting flange, an accommodating cavity is formed at the lower end of the filter screen, a magnetic filter is arranged in the accommodating cavity, a metal rigidity seal ball valve and a metal rigidity seal stop valve are arranged on the buoy below the magnetic filter sequentially, and an air vent valve is arranged at the top of the buoy. The special oil-gas field liquid indicator is novel and unique in structure, jamming, failure and inaccuracy in measurement, blockage at the lower portion communication position, unclear liquid indication and the like can be avoided during use, and the problems about sand removal, blowdown and iron removal are well solved.
Description
Technical field
The utility model relates to measuring instrument field, particularly a kind of oil gas Special level meter with blowdown apparatus.
Background technology
While now using magnetic turnover panel, consider and in measured medium, contain the solid mixtures such as gas, liquid and ceramsite sand, in these solid mixtures, there are a lot of close magnetisable materials: iron powder, iron filings, welding slag, iron content ceramsite sand and ferrous mineral etc., traditional magnetic turnover panel is applied in this environment, only have several hours or several days will be because of a large amount of close magnetic impurity absorption to magnetic float, magnetic turnover panel can be stuck malfunctioning at once, loses value.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of oil gas field Special level meter with blowdown apparatus, can effectively solve measurement bite that existing magnetic turnover panel occurs when measurement contains waste residue and iron content ceramsite sand, malfunctioning, inaccurate, bottom and be communicated with the problem such as stop up, liquid level indication is unintelligible.
Its solution is, comprise floating drum, permanent magnetism float and turning plate indicator, floating drum is provided with for the upper adpting flange of connection container and lower adpting flange, in the floating drum of lower adpting flange lower end, screen pack is housed, screen pack lower end is provided with and holds cavity, hold in cavity and be provided with magnetic filter, be provided with successively metal hard-sealing ball valve and metal hard-sealing stop valve on the floating drum under magnetic filter, vent valve is equipped with at described floating drum top.
The utility model novel structure is unique, in use procedure, there will not be measure bite, malfunctioning, inaccurate, bottom connectivity part is stopped up, liquid level is indicated unintelligiblely etc., and well solved the problem of the blowdown of content gauge sand discharge and deironing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
By Fig. 1, provided, the utility model comprises floating drum 1, permanent magnetism float 2 and turning plate indicator 3, floating drum 1 is provided with for the upper adpting flange 4 of connection container and lower adpting flange 5, in the floating drum 1 of lower adpting flange 5 lower ends, screen pack 6 is housed, screen pack 6 lower ends are provided with and hold cavity, hold in cavity and be provided with magnetic filter 7, be provided with successively metal hard-sealing ball valve 8 and metal hard-sealing stop valve 9 on the floating drum 1 under magnetic filter 7, vent valve 10 is equipped with at described floating drum 1 top.
Described metal hard-sealing ball valve 8 is the metal hard-sealing ball valve of tungsten carbide spraying ball valve, the metal hard-sealing stop valve of described metal hard-sealing stop valve 9 use tungsten carbide spraying valve inner parts.
The magnetic of described permanent magnetism float 2 is lower than magnetic filter 7 magnetic, permanent magnetism float 2 adopts relatively weak magnetic Magnet design, this magnetic is only turned over sheet sensitivity to the magnetic on turning plate indicator 3, through test of many times, prove, irony ceramsite sand or iron filings are entering floating drum 1 when interior, are installed in already magnetic filter 7 absorption of bottom, and permanent magnetism float 2 does not have any ferrous material above and is adsorbed, the utility model can, under normal service condition, can guarantee bite phenomenon can not occur in the several years.
Holding cavity can be used for placing magnetic filter 7, can also deposit from container and enter into the ceramsite sand in magnetic turnover panel floating drum 1, prevents that ceramsite sand from too much stopping up the lower connected entrance that is communicated with flange 5 and floating drum 1.
Described magnetic filter 7 adopts the magnetic filter of ultrastrong magnetic field, be used for adsorbing chalybeate ceramsite sand and other irony impurity, irony impurity in liquid is separated from lower adpting flange 5, guarantee the cleaning ambient that permanent magnetism float 2 is measured in range of movement, avoided permanent magnetism float 2 stuck in floating drum 1 cavity.
Described screen pack 6 is husky screen pack for liquid divides, and described screen pack 6 can prevent that permanent magnetism float 2 from dropping in magnetic filter 7.
Described floating drum 1 is connected on the container that needs to measure through upper adpting flange 4, lower adpting flange 5 and flow stop valve.
The utility model blowoff valve adopts double-valve structure, top adopts the metal hard-sealing ball valve 8 of the superhard matter tungsten carbide spraying valve ball of zero leakage, be used for guaranteeing floating drum blowdown shutoff, realize zero leakage, bottom adopts the metal hard-sealing stop valve 9 of tungsten carbide spraying valve inner part, when guaranteeing to get rid of the sediments such as floating drum 1 bottom ceramsite sand, pressure drainage is steady, bivalve all adopts tungsten carbide trim, it is the ultrahigh hardness of considering ceramsite sand, when blowdown sand discharge with pressure, the ceramsite sand of ejection with pressure is very serious to washing away of trim, tungsten carbide trim can guarantee blowoff valve without leaking long enough in application life.
Blowoff valve sand discharge blowdown operation rules are as follows: the first step is first turn-offed the flow stop valve that floating drum 1 is connected with container, second step is the metal hard-sealing ball valve 8 of opening top, the 3rd the metal hard-sealing stop valve 9 of little by little opening bottom, under the depressurization of metal hard-sealing stop valve 9, the deposits such as ceramsite sand in floating drum 1 excrete from metal hard-sealing stop valve 9, by the time floating drum 1 cavity internal pressure is reduced to atmospheric pressure gradually, after ceramsite sand ejects substantially, open the vent valve 10 at floating drum 1 top, along vent valve 10, pour water and rinse floating drum 1 inside, rinse out a small amount of residual ceramsite sand and other sediment of all floating drum 1 cavitys, the 4th is turn-offed metal hard-sealing ball valve 8 successively, metal hard-sealing stop valve 9 and outlet valve 10, the 5th step is first opened the flow stop valve on the top being connected with container, prevent that permanent magnetism float 2 from being blown up by moment, open again the flow stop valve with the bottom of equipment connection, the 6th step the utility model sand discharge dirt is complete, instrument normally comes into operation, sand discharge blowdown with pressure, the ceramsite sand of ejection can be easy to take away the irony impurity of absorption on magnetic filter 7 at a high speed, magnetic filter 7 is automatically cleaned in sand discharge blowdown process.
The utility model novel structure is unique, in use procedure, there will not be measure bite, malfunctioning, inaccurate, bottom connectivity part is stopped up, liquid level is indicated unintelligiblely etc., and well solved the problem of the blowdown of content gauge sand discharge and deironing.
