Abstract
The utility model discloses an on-line insertion-pull convex diaphragm pressure transmitter. A ball valve is connected to a connector of a device or pipe; a short pipe is connected to the ball valve; a packing groove is formed on the inner side of the top of the short pipe; packing is disposed in the packing groove; a pressing ring is disposed on the packing groove for pressing; and a convex diaphragm is inserted in the pipe or device from the top of the short pipe. The on-line insertion-pull convex diaphragm pressure transmitter can be pulled out from or inserted in the device or pipe under the condition that pressure exists in the device or pipe. When the convex diaphragm needs to be pulled out, a user can pull the convex diaphragm outward into the short pipe, then close the ball valve and thus pull out the convex diaphragm for maintenance or replacement. When the convex diaphragm needs to be inserted in the device or pipe, the user can insert the convex diaphragm to the short pipe position first, add the sealing packing, press the pressing ring properly, open the ball valve and then insert the convex diaphragm to the right place.
Description
Technical field
The utility model relates to a kind of pressure unit, specifically, relate to a kind of can be at the protruding pressing diaphragm power transmitter of OIR.
Background technology
Pressure unit is widely used in pressure and the liquid level of measuring equipment or pipeline, and its convexity pressing diaphragm power transmitter is the pressure unit that a kind of diaphragm stretches to equipment or pipe interior.Diaphragm is for experiencing the pressure of medium, and the liquid (being generally silicone oil) by diaphragm inside to transmitter, and is converted into electric signal by transmitter by pressure signal by pressure conduction.
Protruding pressing diaphragm power transmitter is applied to measure thickness, crystallization, autohemagglutination more, containing situations such as solid particles.But current protruding pressing diaphragm power transmitter can't be changed online, in the situation that equipment or pipeline have pressure to change, because can cause the medium ejection in the situation that equipment or pipeline have pressure to extract protruding diaphragm, cause the adverse effect of safety, environment, production.So in normal productive process, if rupture of diaphragm or transmitter damage, can only stop producing and could change transmitter, cause a large amount of economic losses.
Summary of the invention
To be solved in the utility model is the technical matters that protruding pressing diaphragm power transmitter can't be changed online, provides a kind of online plug-in protruding pressing diaphragm power transmitter, can be in the situation that equipment or pipeline have pressure to be changed.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
The protruding pressing diaphragm power transmitter of a kind of online plug-in, protruding diaphragm is mainly connected to form successively by joint flange, extension tubing, the diaphragm at top, and its diaphragm stretches to equipment or pipe interior.Interface at described equipment or pipeline is provided with ball valve, be connected with short tube on described ball valve, described short tube upper inner is provided with packing groove, be filled with airtight and watertight padding between described packing groove and described protruding diaphragm, described short tube top is equipped with compacting ring for compressing described airtight and watertight padding, described protruding diaphragm inserts from described short tube top, through described short tube, described ball valve, stretches to described equipment or pipe interior.
Preferably, described joint flange and described short tube are bolted to connection.
Preferably, described airtight and watertight padding is PTFE or soft graphite.
Preferably, described compacting ring is fixedly connected with described short tube by bolt.
The beneficial effects of the utility model are:
The protruding pressing diaphragm power transmitter of online plug-in of the present utility model can be in the situation that equipment or pipeline have pressure to extract or insert: when needs are extracted protruding diaphragm, first protruding diaphragm is outwards pulled out to short tube, close again ball valve, both can safe continuing extract protruding diaphragm, overhauled or change; When needs insert protruding diaphragm, at first protruding diaphragm is inserted into to the short tube position, then pack into airtight and watertight padding suitable compression compacting ring, then open the protruding diaphragm of ball valve continuation insertion and put in place.If in the situation that in normal productive process, rupture of diaphragm or transmitter damage and can to extract protruding diaphragm and overhauled or change not stopping.
The accompanying drawing explanation
Accompanying drawing is the structural representation of the protruding pressing diaphragm power transmitter of online plug-in provided by the utility model.
In figure: 1: protruding diaphragm; 11: joint flange; 12: extension tubing; 13: connecting pipe; 14: diaphragm; 15: kapillary; 2: equipment interface; 3: ball valve; 31: valve body; 32: valve ball; 33: handle; 34: ball valve seal ring; 4: short tube; 5: airtight and watertight padding; 6: compacting ring.
Embodiment
Below by specific embodiment, the utility model is described in further detail, following examples can make those skilled in the art more fully understand the utility model, but limit never in any form the utility model.
As shown in drawings, the present embodiment has disclosed the protruding pressing diaphragm power transmitter of a kind of online plug-in, for being arranged on equipment interface 2 places, mainly comprises protruding diaphragm 1, ball valve 3, short tube 4, airtight and watertight padding 5, compacting ring 6.Connect ball valve 3 on equipment interface 2, connect short tube 4 on ball valve 3, in short tube 4 inside top, packing groove is set, in the inner filling of packing groove airtight and watertight padding 5, at the airtight and watertight padding top, compacting ring 6 is set for compressing filler.Protruding diaphragm 1 through short tube 4 and ball valve 3 and equipment interface 2, extend into device interior successively.
Protruding diaphragm 1 comprises the joint flange 11 at top, 11 times welding extension tubings 12 of joint flange, extension tubing 12 bottoms are provided with diaphragm 14, and extension tubing 12 inside are provided with connecting pipe 13, the pressure conduction liquid of connecting pipe 13 inside is connected with diaphragm 14, and connecting pipe 13 tops are connected with kapillary 15.Like this, the pressure signal of device interior can be experienced by diaphragm 14, then conducts and be converted to electric signal through kapillary 15 by pressure conduction liquid.
Airtight and watertight padding 5 is filled between the packing groove and extension tubing 12 of short tube 4, makes between short tube 4 and extension tubing 12 to form good sealing.
In addition, the joint flange 11 of protruding diaphragm 1 also can be fixedly connected with the ring flange of short tube 4 upper ends by bolt and nut, to prevent protruding diaphragm 1, by the pressure of device interior, is ejected.
When needs are extracted protruding diaphragm 1, at first unclamp the bolt and nut that its joint flange 11 is connected with short tube 4, then outwards pull out protruding diaphragm 1, when diaphragm 14 is positioned at short tube 4, close ball valve 3, both can safe continuing extract protruding diaphragm 1, in order to overhauled or change.
When needs insert protruding diaphragm 1, at first protruding diaphragm 1 is inserted in short tube 4, make diaphragm 14 be positioned at short tube 4 inside, then the airtight and watertight padding 5 of packing in the packing groove of short tube 4, and suitably compress compacting ring 6, then open ball valve 3, can continue to insert protruding diaphragm 1 and put in place, finally protruding diaphragm 1 is fixed by bolt and nut and short tube, ejected by pressure to prevent protruding diaphragm 1.
