Background technology
The disclosed pressure sensor device of prior art, major part is applicable to the pressure of measuring liquids and gases, small part is suitable for the pressure of measuring the lower two-phase solid-liquid fluid of concentration, for being applicable to that fully the device of carrying high concentration, full-bodied material pressure to change in the measuring channel does not also have.
For common sensor, material can stop up tracting pressuring hole in the process of measuring high concentration sticky material pipeline transportation, makes ducted pressure can't pass to the sensitive element of sensor, therefore also just can't correctly measure ducted pressure; For the sensor of some diaphragm types,,, be easy to be impacted by high viscosity materials grinding abrasion or the solid granule that contained in the material and cause diaphragm breakage so that lost efficacy because its diaphragm is very thin though in measuring process, there is not the tracting pressuring hole blocking problem.
Summary of the invention
The purpose of this utility model is, overcome the defective that common sensor exists, and provide a kind of have a new structure be used for measuring the sticky material pressure sensor device that high viscosity materials pipe material course of conveying pressure changes, technical matters to be solved is to make it can measure the dynamic response characteristic of high viscosity materials pipe material discharge pressure exactly, and can change measuring point at any time, thereby be suitable for practicality more according to different requirements.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of sticky material pressure sensor device that the present invention proposes, it comprises: a short tube that is connected with main line, and two ends, the short tube left and right sides are flange-type structure, the middle part tube wall place opening of short tube and welding flange form a three-way pipe; An oil resistant rubber barrier film that is used to transmit pressure and plays buffer action, this oil resistant rubber barrier film covers the opening on the short tube; An oil cylinder that is full of hydraulic oil, its lower end is connected in the opening part of short tube, and the inner space of oil cylinder separates by the oil resistant rubber barrier film with the inner space of short tube; And a flange form pressure transducer that is used to measure oil pressure, it is connected in the upper end of oil cylinder.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid sticky material pressure sensor device, wherein said short tube is identical with the caliber of main line, and the short tube two ends have two pipeline connecting flanges, and the flange specification is identical with the main line flange; The flange size of three-way pipe does not change with the variation of main line caliber.
Aforesaid sticky material pressure sensor device, being shaped as of wherein said oil resistant rubber barrier film is dish-like, a side of projection material in short tube, material is an oil resistant rubber.
Aforesaid sticky material pressure sensor device, wherein said oil cylinder are the cylinder bodies that two ends have flange, and end flanges is connected with the three-way pipe flange of short tube under it, and another flange is connected with the ring flange of pressure transducer.
Aforesaid sticky material pressure sensor device, wherein said flange form pressure transducer are with flange fixed pressure sensor, and the pressure transducer flange cooperates with the upper flanges of oil cylinder and be fixing.
The utility model is that a kind of sticky material pressure sensor device is made up of short tube, dish-like diaphragm of rubber, oil cylinder and flange form pressure transducer etc.Described short tube is identical with the main line structure, and two ends are pipeline flange connecting, at the three-way pipe of tube wall opening and the flange that is connected the pressure transmission device of short tube; Dish-like diaphragm of rubber is recessed, the flat circular oil resistant rubber film all around in centre; Oil cylinder is the hydraulic oil of sealing up for safekeeping between diaphragm of rubber and the pressure transducer.
When in the pipeline during convey materials, sticky material enters from an end of short tube, and the other end flows out.Because the effect of pressure, sticky material can be full of whole short tube in course of conveying, so just push dish-like diaphragm of rubber.Because the barrier film upper end has been full of hydraulic oil, and the deformation that produces behind the oily pressurized is very little, so barrier film directly passes to in-oil cylinder pressure oil to the pressure of the sticky material that affords.According to the equilibrium of forces principle, the pressure at barrier film two ends equates that promptly the pressure of the interior oil of oil cylinder is the pressure of sticky material in the pipeline.Therefore measure the pressure of oil in the oil cylinder by general pressure transducer, just can obtain the suffered pressure of material in the pipeline.
By technique scheme, the utility model has following advantage at least:
The utility model provides a kind of sensing device that is used for measuring the variation of high viscosity materials pipe material course of conveying pressure of new structure.This device can be measured the dynamic response characteristic of high viscosity materials pipe material discharge pressure exactly, and can change measuring point (as long as in installation pipeline, in the place that is needing gaging pressure short tube being installed in advance) at any time according to different requirements, have advantages such as life-span long (can change impaired diaphragm of rubber easily), dismounting be easy.
The short tube of the utility model sticky material pressure sensor device is connected with transfer pipeline, the physical dimension of the caliber of short tube and two ends joint flange designs according to the size of transfer pipeline fully, variation and fluctuation with regard to can not be different and producing pressure like this because of the size of measuring point and transfer pipeline, thus avoid causing error in the measurement.
Illustrate
Fig. 1 is the sectional view of the utility model sticky material pressure sensor device.
Embodiment
Seeing also shown in Figure 1ly, is the sectional view of the utility model sticky material pressure sensor device.It is that pipeline connecting flange, middle part are the short tube 1 of oil cylinder joint flange that the utility model sticky material pressure sensor device has two ends, 2, one oil-overflow oil cylinders 3 of dish-like diaphragm of rubber and a flange form pressure transducer 4 of measuring oil pressure that plays pressure transmission and buffer action.
