Description
The utility model relates to a kind of measurement instrument, especially for the instrument of measuring liquid level.
At present the measurement to liquid level generally is the liquid level gauge that adopts throw-in type in petroleum chemical industry, because that anticorrosion problem is not solved result of use effectively is unsatisfactory.There is the people to design the anticorrosion measurement instrument of exogenous again for this reason, as on Dec 8th, 1993 disclosed a kind of＜the level sensing instrument (application number 92235854.0) its primary structure is: the flange at housing two ends respectively with the fluid to be measured tank body on flange and the flange of pressure transducer be connected, be provided with the V-type inner chamber that the both ends horizontal section communicates with flange in the housing, be positioned at the join flange of a side of V-type inner chamber and tank body and be provided with the isolation capsule of end Tourniquet clamping head, in the V-type inner chamber spacer pad is housed.Its weak point is that housing is difficult for processing and manufacturing, the undesirable easy leakage of separator sealing effectiveness.
The purpose of this utility model is to provide the anti-corrosive apparatus of a kind of easy processing simple in structure, the leak free liquid level instrument of separator.
The purpose of this utility model can realize by following measure: a kind of anti-corrosive apparatus of liquid level instrument, it is characterized in that: two sections horizontal housings are established a through hole up and down for every section, respectively establish the vertical short tube that there is plug an end on the hole again, wherein the sample flange of piece housing one end and the flange of basin valve is complementary, the other end has with the be complementary flange of groove of pressure cap and is connected with the flange of pressure transmission piece housing band groove, be equipped with barrier film on this end face of pressure transmission section, establish the pressure cap that end face has small through hole internal perisporium screw thread to link to each other with screw thread on the shell end outer peripheral face on it, the other end of pressure transmission piece housing can link to each other with sensor housing.Be provided with annular groove on the end face of pressure transmission piece housing, the pressure ring that is complementary with this groove places on this groove and fastening by pressure cap across barrier film.
The utility model mainly includes barrier film, pressure cap and housing.It is pressure transmission section and sampling section that its middle shell is divided into two parts, and the pressure transmission piece housing is horizontal body, and it respectively establishes a through hole up and down, respectively establishes the vertical short tube that there is plug an end on the hole again, and last pipe is the liquid injection pipe gas outlet of holding concurrently, and following pipe is a discharging tube.One end of this housing is connected with sensor, and it can be that to weld also can be that flange connects with being connected of the sensor housing that is provided with sensor.Be equipped with barrier film on the end face of the housing other end greater than its aperture.This has the corrosion resistant barrier film of certain intensity and is fixed by pressure cap.The top of this flute profile pressure cap is provided with some small through hole, and it neither influences passing through of fluid and the pressure of liquid can be disperseed, and barrier film is shielded.The screw thread of pressure cap internal perisporium and this shell end outer peripheral face screw thread link to each other.The end face that is preferably in this housing is provided with annular groove, and the pressure ring that is complementary with this groove places on the groove fastening by pressure cap again across barrier film, can increase sealing effectiveness like this.Also be provided with the flange of band groove at this end of this housing.The sampling piece housing also is horizontal body, and it also respectively establishes a through hole up and down, respectively establishes the vertical short tube that a radicle has plug on the hole again.Last pipe is managed down for gas outlet and is discharging tube.A flange is respectively established at the two ends of this housing, the flange of valve is complementary on the flange of one end and the fluid to be measured basin, the flange of the other end has groove, itself and pressure transmission piece housing also are connected to form whole housing with the flange of groove by securing member, and in the folded space of above-mentioned two flanges can be included in pressure cap, barrier film and pressure ring.
The pressure transmission section of this device and the interior housing that pressure transducer arranged and the supporting with it detection system formation height displaying instrument table that links to each other.Earlier inject the non-corrosive neutral liquid of pressure transmitting medium by this device pressure transmission Duan Shangguan in it during use, the sampling section with this device links to each other with the valve of fluid to be measured basin then.The sampling section that valve liquid in it of opening basin during measurement just enters housing contacts with barrier film after the buffering of the aperture on the pressure cap, this barrier film is subjected to the pressure that the weight of fluid column own produces in the jar and is out of shape, the deformation of barrier film passes to pressure-active element on the pressure transducer by pressure transmitting medium, and it becomes electric signal to amplify output current through voltage transitions pressure signal to deliver to display instrument demonstrates fluid to be measured at last with data mode through a series of data processing height value.
Drawing is described as follows:
Fig. 1 is that master of the present utility model looks synoptic diagram.
Fig. 2 is that the master of the utility model embodiment looks synoptic diagram.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the synoptic diagram of the anti-corrosive apparatus of liquid level instrument shown in Figure 1, sampling piece housing 1 is respectively established a radicle up and down has the short tube of plug promptly to go up pipe 2, manage 3 down.A flange is respectively established at the two ends of this housing, and the flange of its left end 4 is complementary with flange on the basin valve, and the flange 5 of right-hand member has the groove that is complementary with pressure cap and is complementary with the flange that has groove of pressure transmission section.Pressure transmission piece housing 6 is also respectively established the short tube that a radicle has plug up and down, promptly goes up pipe 7 and manages 8 down.One end of this housing can be connected with sensor housing, the end face of the other end is provided with annular groove, teflon barrier film 9 places on the end face by pressure ring 10 location that are complementary with annular groove, on pressure ring, be provided with pressure cap 11 again, pressure cap that this housing is threaded top is provided with some small through hole, this end of this housing also be provided with the band groove flange 12 it be connected by securing member with the flange of sampling section right-hand member.
