Abstract
The invention discloses a compound flow tube for an ultrasonic heat meter, and is characterized in that: a stainless steel tube is embedded in a plastic tube body; the plastic tube body of the compound flow tube is provided with a water inlet threaded nipple and a water outlet threaded nipple; and the plastic tube body is provided with a matched pair of a temperature sensor installation hole and an ultrasonic transducer installation hole I, II communicated with the stainless steel tube. Because the stainless steel tube is embedded in the plastic tube body, the stainless steel tube serving as the inner wall of the compound flow tube is high in strength, resistant to corrosion, and high in surface smoothness, and the sewage is not easy to hang; the tube body of the compound flow tube is made of plastics, so the tube body is easy for injection molding or compression molding; the water inlet threaded nipple and the water outlet threaded nipple arranged on the plastic tube body of the compound flow tube, and the matched pair of the temperature sensor installation hole and the ultrasonic transducer installation hole I, II communicated with the stainless steel tube arranged on the plastic tube body are all molded by the injection molding or the compressing molding at a time, so the subsequent machining workload is reduced, and the compound flow tube has the advantages of low cost, high cost performance, long service life and the like.
Description
Technical field
The present invention relates to the flow measurement device technical field, is a kind of ultrasonic calorimeter combined type flowtube.
Background technology
At present, the measuring ultrasonic wave flow technology is used on the calorimeter very ripe, mainly is made of flowtube, ultrasonic transmission device and measuring apparatus on the structure, and wherein, flowtube mainly adopts aldary or stainless steel or plastic material manufacturing.The flowtube of being made by aldary generally adopts die forging processing and machining because drawing abillity is good, and production efficiency height, precision are good, are widely adopted, but because the Cu alloy material cost is higher, cause flowtube finished product cost also high; By the flowtube processing technology complexity that stainless steel is made, generally adopt casting method processing, and the stainless steel machinery poor processability, manufacturing cost is higher; Flowtube material cost and the processing cost made by plastic material are all very low, can adopt the injection moulding process moulding, be suitable for producing in enormous quantities, but because the compressive resistance of plastic material own is lower and the back that is heated easily produces distortion and aging, therefore, on the heat quantity flow pipe, seldom adopt.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of cost, ratio of performance to price height, the ultrasonic calorimeter of long service life combined type flowtube.
The objective of the invention is to realize: a kind of ultrasonic calorimeter combined type flowtube by following technical scheme, it is characterized in that: it constitutes by inlay stainless-steel tube in plastic tube body, the plastic tube body of combined type flowtube is provided with water inlet threaded connector and water delivering orifice threaded connector, is provided with the pairing temperature sensor mounting hole, ultrasonic transducer mounting hole I and the ultrasonic transducer mounting hole II that are communicated with stainless-steel tube on the plastic tube body of combined type flowtube.
Because adopting with the combined type flowtube, ultrasonic calorimeter of the present invention in plastic tube body, inlays the stainless-steel tube formation, that is use the mould combined type flowtube that composite plastic is made on stainless-steel tube, its stainless-steel tube intensity height, corrosion resistant, surperficial luminosity height dirt not easy to hang as combined type flowtube inwall with plastics; Be easy to injection moulding or compression molding with plastics as the body of combined type flowtube, the entery and delivery port threaded connector that is provided with on the plastic tube body of combined type flowtube, the pairing temperature sensor mounting hole that is communicated with stainless-steel tube, ultrasonic transducer mounting hole I and the II that are provided with on the plastic tube body are all by injection moulding or compression moulding one-shot forming, reduced follow-up machining workload, it is low to have cost, ratio of performance to price height, advantages such as long service life.
Description of drawings
Fig. 1 is a ultrasonic calorimeter of the present invention combined type flowtube structure cross-sectional schematic.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Fig. 3 is a B-B cross-sectional schematic among Fig. 2.
Among the figure: 1 plastic tube body, 2 ultrasonic transducer mounting hole I, 3 stainless-steel tubes, 4 ultrasonic transducer mounting hole II, 5 water inlet threaded connectors, 6 pairing temperature sensor mounting holes, 7 water delivering orifice threaded connectors.
Embodiment
The invention will be further described to utilize the drawings and specific embodiments below.
With reference to Fig. 1-3, ultrasonic calorimeter of the present invention is to inlay stainless-steel tube 3 to constitute in plastic tube body 1 with the combined type flowtube, the plastic tube body 1 of combined type flowtube is provided with entery and delivery port threaded connector 5,7, is provided with the pairing temperature sensor mounting hole 6, ultrasonic transducer mounting hole I 2 and the ultrasonic transducer mounting hole II 4 that are communicated with stainless-steel tube 3 on the plastic tube body 1 of combined type flowtube.
Stainless-steel tube 3 as combined type flowtube inwall can adopt circle, square or rectangular tube, its diameter of bore or highly be that 15～50mm is corresponding with the calorimeter specification, and wall thickness is generally 0.5～3mm, can determine according to caliber and concrete material.[0017] according to the designing requirement of flowtube pipe in the stainless steel is processed, interior length of tube can with flowtube is isometric also can be slightly short, need flowtube need with position (as transducer mounting hole and the pairing temperature sensor mounting hole etc.) perforate as required that is communicated with outside the pipe.
For guaranteeing the bond strength of stainless-steel tube 3 and plastic tube body 1, can carry out hacking to stainless-steel tube 3 outside surfaces and handle.
Good engineering plastics of intensity and heat resistance or plastic alloy are generally selected in the selection of plastic tube body 1 material for use.
During making, stainless-steel tube 3 is put into mould,, stainless-steel tube 3 is embedded in the plastic tube body 1, make plastic tube body 1 and stainless-steel tube 3 compound becoming one with plastic injection-moulded or compression molding; The entery and delivery port threaded connector 5,7 that is provided with on the plastic tube body 1 of combined type flowtube, the pairing temperature sensor mounting hole 6 that is communicated with stainless-steel tube 3, ultrasonic transducer mounting hole I 2 and the II 4 that are provided with on the plastic tube body 1 are all by injection moulding or compression moulding one-shot forming.
One-time formed method realized when flowtube measuring section endoporus reducing can adopt injection moulding, and reducing place size can partly or entirely be formed by the engineering plastics material
The hole height 15～50mm of pairing temperature sensor mounting hole 6, ultrasonic transducer mounting hole I 2 and the II 4 that is provided with on the plastic tube body 1 of combined type flowtube.
