Description
Technical field
The present invention relates to a kind of device that is used for the measuring media temperature, particularly a kind of corrosion-proof temp-measuring sensor of measuring high temperature, high pressure, strong corrosive environment medium temperature.
Background technology
At present, the temperature probe of measuring various medium temperatures has been widely used in industries such as power station, petrochemical complex, metallurgy, papermaking, weaving, pharmacy.Existing temperature probe adopts contact and contactless structure mostly.Contactless temperature probe is longer serviceable life, corrosion-resistant, but its complex structure, manufacturing cost is higher, and the thermometric accuracy is relatively poor.And the temperature-sensing element of contact structure is assembled in the fixing protection metal pipe of utilization connection bearing, directly places point for measuring temperature, and relatively simple for structure, thermometric is accurate, and sensitivity is higher.Relatively poor because of the physical strength of resistant material commonly used, what have is not easy to machining, so relevant connection parts and protection tube thereof generally adopt the metal material processing manufacturing.Therefore, be subjected to its structure to limit the medium that can not be used for measuring high temperature, high pressure, strong corrosive environment.For overcoming above-mentioned defective, adopt outside surface spraying resistant material protective layer usually at protection metal pipe, because of coating inhomogeneous or its surperficial pore is arranged, so the easy seepage of strong corrosive medium can reduce its serviceable life.The employing fluorine plastic tube that also has adds corrosion-resistant protective layer in the method for protection metal pipe periphery with the stretch flanging press seal.But, because fluorine plastic tube is after the protection metal pipe periphery rolls the stretching press seal, can't stretch that to cause managing arm in uneven thickness to rolling of its existence, produce internal stress, can cause seepage; Flange place behind the flange has stress to concentrate, and bigger stress can not bear in this place, causes disadvantages such as seepage during pressure-bearing easily, detects, and influences it and applies.According to domestic and international open source literature report, up to now, also there is not the sensor of desirable measurement high temperature, high pressure, strong corrosive environment medium temperature.Therefore, existing temperature probe is being treated further improvement.
Summary of the invention
The purpose of this invention is to provide a kind of corrosion-proof temp-measuring sensor, its reasonable in design, encapsulation locking are firmly, sealing is reliable, overcome disadvantages such as easy to leak, serviceable life that prior art exists is low effectively, significantly improve anticorrosion effect and serviceable life, widen the scope of application of measurement.
The object of the present invention is achieved like this: this device comprises that the outside surface that utilizes the connection bearing to fix is compounded with the protection metal pipe of anti-corrosion protecting tube and is assembled in the interior temperature-sensing element of protection metal pipe; it is characterized in that: described anti-corrosion protecting tube together is fixed on protection metal pipe and is connected in the bearing; and utilize anti-corrosion flexible sealing plug and anti-corrosion sealing shroud by split type pair of threaded line pipe encapsulation locking; encapsulate split type pair of threaded line pipe of anti-corrosion flexible sealing plug and anti-corrosion sealing shroud; adopt cylinder lock lock ring or flange form locking strap to lock respectively and reinforce, at last cylinder lock lock ring or flange form locking strap are fixed together with the described bearing that is connected.
Because the present invention is the protective approach that fundamentally changes the protection tube of existing temperature-sensing element; the parts that will contact with strong corrosive medium; whole assemblies that adopt resistant material to make; reasonable in design; encapsulation locking firmly, sealing is reliable, so solved problems such as easy to leak, serviceable life that prior art exists is low effectively.In addition, because of said modules not only can be hunted leak in advance, make it to bear 20MPa with downforce, energy measurement negative pressure again, re-use after guaranteeing not have any leakage, and can use the medium of measuring and different measurement temperature ranges according to reality, selecting different anti-corrosion materials to be processed into corresponding corrosion-resistant piece locking is integral, become the desirable temperature measuring equipment of measuring various media in high temperature, high pressure, the strong corrosive environment, so can significantly improve the anticorrosion effect and the serviceable life of this device, widen the scope of application of measurement.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a kind of concrete structure synoptic diagram that is threaded of the present invention.
Fig. 2 is the concrete structure synoptic diagram that a kind of flange of the present invention connects.
Embodiment
Describe the concrete structure of the present invention and the course of work in detail according to Fig. 1-2.This device is made the structure that the structure that is threaded as shown in Figure 1 is connected with flange as shown in Figure 2 according to request for utilization.It comprises temperature-sensing element 1, anti-corrosion protecting tube 2, protection metal pipe 3, anti-corrosion sealing shroud 4, split type pair of threaded line pipe 5, anti-corrosion flexible sealing plug 6, locking strap 7, connects parts such as bearing 8, flange form locking strap 9.Wherein temperature-sensing element 1 can adopt the temperature-sensing element of various types of commercial sensor, and its end is assembled in the protection metal pipe 3.Protection metal pipe 3 outside surfaces are compounded with anti-corrosion protecting tube 2, and anti-corrosion protecting tube 2 can adopt resistant material, as materials processing moulding such as pottery, fluoroplastic, corrosion resistant metals.Anti-corrosion protecting tube 2 is through after the assay was approved, together is fixed on protection metal pipe 3 to be connected in the bearing 8, carries out sealing-in.Then, utilize again by resistant material, anti-corrosion flexible sealing plug 6 and anti-corrosion sealing shroud 4 as materials processing moulding such as fluoroplastic, soft graphites, by split type pair of threaded line pipe 5 and locking strap 7 or the 9 encapsulation lockings of flange form locking strap, at last, with locking strap 7 or flange form locking strap 9 be connected bearing 8 affixed being integral.
For the ease of assembling processing, encapsulate split type pair of threaded line pipe 5 of anti-corrosion flexible sealing plug 6 and anti-corrosion sealing shroud 4, adopt the cylinder lock lock ring 7 have internal thread or flange form locking strap 9 to lock respectively and reinforce, the present invention is made the structure that the structure that is threaded or flange connect.In addition, in split type pair of threaded line pipe 5, the axial location platform is set, in the locking process, axial float takes place to prevent anti-corrosion flexible sealing plug 6 and anti-corrosion sealing shroud 4.This device is when using below 200 ℃, and above-mentioned corrosion-resistant parts adopt fluoroplastic, make as teflon, perfluoroethylene-propylene or other resistant material etc.Using below 1800 ℃ or during negative pressure, protection metal pipe 3 and anti-corrosion protecting tube 2 can be used Al
2O
3Stupalith or other resistant material are made the complex pipe of integral structure.When surveying hydrochloric acid, anti-corrosion protecting tube 2 also can adopt corrosion resistant metals such as metal tantalum.
