Description
The utility model relates to a kind of measurement instrument, especially for the instrument of measuring liquid level.
Measurement to liquid level generally is the liquid level gauge that adopts throw-in type in petroleum chemical industry at present, is not gone into meaning not to the utmost because anticorrosion problem solves result of use effectively.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 V-type inner chamber housing is difficult for adding the formula manufacturing, and the teflon in it isolates that capsule is more difficult to add manufacturing, and therefore the valve of isolating capsule and endpiece all can not can make whole anti-corrosive apparatus lose efficacy by high-seal.
The purpose of this utility model is to provide the anticorrosion sensing mechanism of a kind of easy process and assemble simple in structure, the leak free fluid level measuring instrument of sealing.
The purpose of this utility model can realize by following measure: a kind of anticorrosion sensing mechanism of exogenous fluid level measuring instrument, it is characterized in that: establish a through hole above every section of two sections horizontal housing, respectively establish the vertical short tube that there is plug an end on the hole again, wherein the flange of the flange of entrance housing one end and basin valve is complementary, the flange of the other end is connected with the flange of outlet section housing, the outlet section flange that this end face is provided with annular groove is provided with barrier film outward, the barrier film outside is provided with the trim ring that is complementary with annular groove again, outside trim ring, also be provided with the tight flange of envelope, the tight flange of this envelope middle part has on the small through hole periphery screw hole is arranged, screw in the hole is fixed on the flange of outlet section housing, and the flange of the pressure transducer outer end of establishing in the set flange of the other end of outlet section housing and the housing is connected by securing member.Every piece housing following established a through hole, respectively establishes the vertical short tube that there is plug an end on the hole again.Be provided with the orifice plate of small through hole at the interface of the adjacent end of entrance housing with the outlet section housing.
The utility model mainly includes housing, film, trim ring, the tight flange of envelope and pressure transducer (or fluid level transmitter).It is entrance and outlet section that its middle shell is divided into continuous two parts.The entrance that one end flanges can link to each other with fluid to be measured basin valve 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 short tube is a gas outlet, and following short tube is a discharging tube.The flange of this section other end is corresponding with the flange of outlet section housing and can be connected by securing member.The interface that is preferably in the adjacent end with the outlet section housing of entrance housing is provided with the orifice plate of small through hole, and it not only can influence passing through of fluid but also can stop that solid particle can also disperse the pressure of liquid barrier film is shielded simultaneously.The outlet section housing also is horizontal body, and it also 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 short tube is the liquid injection pipe gas outlet of holding concurrently, and following short tube is a discharging tube.Link to each other with the entrance housing end face of an end flanges of outlet section housing is provided with annular groove.Outside this end face, be provided with barrier film greater than the annular groove external diameter.This has the corrosion resistant barrier film of certain intensity and is provided with the annular trim ring that is complementary with annular groove outward again, just barrier film is compressed into groove when it places in the groove and seals.Be provided with the tight flange of envelope again in the outside of trim ring, there is small through hole at this plectane middle part that is located between the two-piece housing flange, and the interior orifice plate of its effect and entrance housing is identical.Be provided with screw hole on the periphery of the tight flange of envelope, the screw that passes this hole can be fastened on the flange of outlet section housing the tight flange of envelope so that trim ring is compressed.The other end of outlet section housing also is provided with flange, and the flange of the sensor outer end of establishing in itself and the housing is complementary and is fastening by securing member.The pressure transducer in this housing and the formation height displaying instrument table that links to each other with its supporting detection system.Earlier in it, inject pressure transmitting medium during use by short tube on the outlet section housing, promptly non-corrosive neutral liquid, the entrance housing with this mechanism links to each other with the valve of fluid to be measured basin then.Its interior liquid of valve of opening basin during measurement just enters the entrance housing, contacts with barrier film after sealing tight flange buffering.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, it becomes electric signal amplification output current to deliver to display instrument through voltage transitions pressure signal, demonstrates the height value of fluid to be measured at last with data mode through a series of data processing.
Drawing is described as follows:
Fig. 1 is that master of the present utility model looks synoptic diagram.
