Abstract
The utility model discloses a pressure measurement device for pulsatory high-pressure corrosive medium, which consists of a connecting flange, an isolating diaphragm, a transmissible capillary tube and a pressure transmitter, the connecting flange is mounted on a pipeline for delivering pulsatory high-pressure corrosive medium, the isolating diaphragm is mounted in the flange, one end of the transmissible capillary tube is connected with the connecting flange, the other end of the transmissible capillary tube is connected with the pressure transmitter, and the surface of the isolating diaphragm, which is contacted with the medium, is provided with a hardened layer. The device has the advantages of pulsatory high pressure resistance, high-temperature corrosion resistance, accurate measurement and high stability, and moreover, the service life is relatively prolonged.
Description
Technical field
The utility model relates to the pipeline pressure measurement mechanism, particularly a kind of remote measuring unit of carrying the Korrosionsmedium pipeline pressure.
Background technology
The device for pressure measurement of existing pulsation high pressure Korrosionsmedium mainly is made up of pressure unit and teletransmission packoff; The teletransmission packoff comprises teletransmission flange, isolation diaphragm, teletransmission kapillary (in charge topping up).During work, pressure process transmits filling liquid by isolation diaphragm, and filling liquid transfers the pressure on the pressure-sensitive diaphragm of center sensor, and pressure-sensitive diaphragm is the flexible member of a tensioning, and its displacement changes with institute's pressurized; And the pressure-sensitive diaphragm displacement is directly proportional with the pressure size, and the capacitor plate of both sides detects the position of pressure-sensitive diaphragm, and the difference of electric capacity is converted into corresponding electric current (4～20mA) output signals between pressure-sensitive diaphragm and the capacitor plate.The device for pressure measurement of existing pulsation high pressure Korrosionsmedium, major defect is as follows: (1) elevated temperature corrosion resistant is poor, and when measuring high temperature corrosion and being flow media, isolation diaphragm very easily causes the corrosion resistance reduction breakdown because of high temperature friction washes away; (2) anti-pulsation high pressure is poor, and when measuring dynamic media, owing to belong to the pulsation high pressure, isolation diaphragm is easy to be out of shape by impact extruded even rupture, and causes measuring error even invalid occurring.No matter be which kind of reason causes the isolation diaphragm damage all can't to repair and change, can only allow instrument scrap, cause very big waste.
As from the foregoing, the device for pressure measurement of above-mentioned existing pulsation high pressure Korrosionsmedium obviously has defective and exists, and remains to be improved.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of utility model of reasonable in design and effective above-mentioned defective finally.
Summary of the invention
The purpose of this utility model aims to provide a kind of device for pressure measurement of the high pressure Korrosionsmedium of pulsing, and guaranteeing this device anti-pulsation high pressure, elevated temperature corrosion resistant, measurement precision and to have good stability, and prolong serviceable life relatively.
For reaching above-mentioned purpose, the utility model provides a kind of device for pressure measurement of the high pressure Korrosionsmedium of pulsing, comprise being installed on the connecting flange of carrying on the pulsation high pressure Korrosionsmedium pipeline, be assemblied in the isolation diaphragm in the described flange, and teletransmission kapillary and pressure converter; Teletransmission kapillary one end and described connecting flange link, and the teletransmission other end capillaceous connects with the pressure converter, and the surface in contact of described isolation diaphragm and medium is provided with hardened layer.
The thickness of described hardened layer is 0.5 millimeter.
Because the surface in contact of isolation diaphragm is provided with hardened layer, compared with prior art, the utlity model has following advantage:
1, diaphragm of the present utility model has improved elevated temperature corrosion resistant and wearing quality, has prolonged the serviceable life of diaphragm, has widened the actual scope of application of transmitter, has strengthened the transmitter measuring stability simultaneously.
2, Jia Hou diaphragm can bear more high pressure, especially the pulse impact extruded of high pressure, the diaphragm useful working life prolongs significantly, still working stability is effective to make transmitter be in impact conditions for a long time, transmitter is reduced the restrictive condition of actual condition, improved accuracy and stability that transmitter is measured simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is installed in synoptic diagram on the pipeline for connecting flange;
In the accompanying drawing: 1-isolation diaphragm 2-connecting flange 3-teletransmission kapillary 4-pressure converter 5-pipeline.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, connecting flange 2 is installed in to be carried on the Korrosionsmedium pipeline 5, isolation diaphragm 1 is installed in the connecting flange 2, isolation diaphragm 1 directly contacts with Korrosionsmedium, isolation diaphragm 1 is provided with hardened layer with the surface in contact of medium, the thickness of hardened layer is 0.5 millimeter, and the gross thickness when processing isolation diaphragm 1 will increase by 0.5 millimeter like this; If isolation diaphragm 1 is selected low-carbon (LC) (alloy) steel for use, need that surface in contact is carried out carburizing and quenching and handle; If isolation diaphragm 1 is selected middle carbon (alloy) steel for use, can directly carry out high-frequency quenching to the surface in contact of isolation diaphragm 1 handles, certainly can also adopt other case hardening process, the thickness of hardened layer need be controlled within the specific limits, and 0.5 millimeter hardened layer is a preferred thickness.Teletransmission kapillary 3 connects connecting flange 2 with pressure converter 4, outside larger distance, just can directly measure the pressure of conveyance conduit 5 internal corrosion media like this.
