Abstract
The utility model relates to a pipe thick liquid-delivery pressure-surveying device, comprising a connecting flange which is communicated with a thick liquid-delivery pipe, a membrane shell, a rubber isolation membrane, a pressure guiding chamber, and a pressure meter or a pressure sensor. The pipe thick liquid-delivery pressure-surveying device is suitable for the pressure measurement of pipe delivery thick liquid. The utility model has the advantages of simple structure, low cost, and high measuring precision; the pipe thick liquid-delivery pressure-surveying device can avoid blockage.
Description
The utility model relates to a kind of plurality of fluid pressure gauges, particularly is applicable to the pressure survey of high density slurry pipeline transportation.
In the high density slurry pipeline transportation, the measurement of slurry pressure is not still had measuring equipment preferably at present, generally use ordinarily manometer directly to be installed on the slurry pipeline, very easily result in blockage, measuring error is big, even instrument is damaged.1151 serial condenser type teletransmission flange pressure transmitters of company of Rosemount China Inc. (Rosemount) development, be used in the pressure survey of the defeated slurry of pipeline, it is to import transmitter into by stainless steel isolation diaphragm, kapillary, its oil-extended process complexity, after isolation diaphragm, kapillary damage, maintenance difficult, instrument costs an arm and a leg, be used for pipeline multistage slurry pressure and measure, certainly will invest excessive.The differential teletransmission tensimeter of domestic existing YTT--150A type YP type diaphragm manometer all is applicable to the pressure survey of Korrosionsmedium, steam medium, is diverted to the high density slurry pressure survey, still has blockage problem.
Task of the present utility model provides a kind of slurry pressure measurement mechanism that has the transition putamina on the slurry pipeline that prevents to stop up, directly be installed in.
Its main points are to be communicated with to have the joint flange of leading the slurry short tube on slurry pipeline, putamina of the airtight connection in this joint flange top, slurry enters leads the slurry short tube, and the rubber isolation diaphragm of compressing putamina, its pressure is passed to tensimeter or pressure transducer by silicone oil pilot chamber, pressure guide hole on the rubber isolation diaphragm, measures the pressure of slurry.
Describe the utility model structure and embodiment in detail below in conjunction with accompanying drawing.
The utility model front section view shown in Figure 1.
The defeated slurry of pipeline device for pressure measurement comprises that being welded on leading on the slurry pipeline 1 starches short tube 5 as shown in Figure 1, leads slurry short tube top and is threaded with joint flange 4; Flushing port 3 is set on joint flange, and this flushing port communicates with leading the slurry short tube, in order to the periodic flushing slurry particles, with anti-clogging; Install putamina 10 on binding flange top, the bottom adhesive rubber isolation diaphragm 6 of putamina, putamina central authorities on this isolation diaphragm top form silicone oil pilot chamber 7, top, pilot chamber communicates with pressure guide hole 8, this pressure guide hole plays damping action when slurry has than great fluctuation process, pressure guide hole 8 connects tensimeter or pressure transducer 9 until the putamina top; On putamina, be provided with the oil-filled hole 2 of oil-filled valve, and communicate with silicone oil pilot chamber; Putamina 10 and joint flange 4 usefulness connected nuts 11 airtight connecting as one.
Slurries in the slurry pipeline 1 enter leads slurry short tube 5, and the rubber isolation diaphragm 6 on the compressing putamina 10, import its slurries pressure into pilot chamber 7, affact the sensitive element of tensimeter or pressure transducer, indicate force value by the silicone oil in pilot chamber, the pressure guide hole.
Advantage of the present utility model: simple in structure, cost is low; Adopt rubber isolation diaphragm, replacing and easy to maintenance; Need not vacuumize, can directly fill silicone oil by oil-filled hole to the pilot chamber; Flushing hole is set, and the slurry short tube is led on time flushing, and the generation of stopping to stop up improves certainty of measurement.
Claims (3)
1, the defeated slurry of a kind of pipeline device for pressure measurement, formed by lead slurry short tube 5, joint flange 4, tensimeter or the pressure transducer 9 that are communicated with slurry pipeline, it is characterized in that airtight connection putamina 10 on joint flange, at the bottom of putamina adhesive rubber isolation diaphragm 6, pilot chamber, pressure guide hole are set on isolation diaphragm top.
2,, it is characterized in that on putamina, being provided with the oil-filled hole 2 that has oil-filled valve that communicates with the pilot chamber according to the described device for pressure measurement of claim 1.
