Technical Field
The utility model relates to the technical field of temperature measuring element sleeves, in particular to an anti-corrosion thermometer protective sleeve.
Background
To monitor the temperature of the fluid within the pressure vessel or conduit, a thermometer is inserted into the wall of the pressure vessel or conduit. In order to avoid direct contact between the fluid and the thermometer, the thermometer is arranged in a protective sleeve which is fixed with the pressure vessel or the pipeline. The existing sleeve is generally composed of a connecting flange and a sleeve main body, wherein the bottom end of the sleeve main body is closed, the top end of the sleeve main body is open, and the top end of the sleeve main body is fixed on the inner edge of the connecting flange in a welding mode. In order to ensure the heat-conducting property of the sleeve body, the wall thickness of the sleeve body is not very thick, but only the top end of the sleeve body is fixed with the connecting flange. When the measurement medium is corrosive, a tetrafluoro-sleeve is typically used to protect the thermometer. Because the liquid flows in the pipeline, the sleeve bears a thrust, and when the fluid is unstable, the thermometer protective sleeve also has a back and forth swinging movement trend, so that the temperature protective sleeve is broken, the acid-proof lining is damaged, and the temperature sensing element and the liquid leakage are damaged.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model aims to provide an anti-corrosion thermometer protective sleeve, which solves the problems existing in the prior art, greatly improves the measurement stability and reliability of a thermometer and prevents production faults caused by the breakage of the protective sleeve.
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
As shown in fig. 1, the embodiment provides an anti-corrosion thermometer protection sleeve, which comprises a sleeve body and a connecting flange 1, wherein the connecting flange 1 is coaxially fixed at the upper part of the sleeve body; the part of the sleeve body below the connecting flange 1 is a conical section 3 with gradually reduced diameter from top to bottom, and an anti-corrosion layer is laid on the surface of the conical section 3. The sleeve body is internally and coaxially provided with a blind hole 4 for installing a thermometer, the blind hole 4 extends to the bottom of the conical section 3, and the size of the blind hole 4 is matched with the size of the thermometer.
When in use, the connecting flange 1 is arranged on a pipeline or other container, and the conical section 3 extends into the pipeline or the container; and then the thermometer is inserted into the blind hole 4 for fixing.
The temperature measurement principle of the thermometer is that the medium transfers heat to the sleeve body, and then the sleeve body transfers heat to the thermometer for temperature measurement. Since the bottom end of the blind hole 4 extends to the bottom of the conical section 3 in this embodiment, the measuring end of the thermometer is also located at the thinner end of the conical section 3, where the thickness of the sleeve body is thinner, the heat transfer efficiency is higher, and the measuring accuracy is fully satisfied. Moreover, the larger end of the conical section 3 is connected with the connecting flange 1 in the embodiment, so that the rigidity of the sleeve body is higher, the strength of the connecting position of the sleeve body and the connecting flange 1 is higher, and the shock resistance and the vibration resistance are stronger, thereby greatly improving the measurement stability and the reliability of the thermometer and preventing production faults caused by the breakage of the protective sleeve.
The anti-corrosion layer laid on the surface of the conical section 3 can protect the sleeve body from being corroded by the medium, and the sleeve body can maintain the shape of the anti-corrosion layer. Compared with the sleeve made of the anti-corrosion material in the prior art, the anti-corrosion layer in the embodiment is less prone to bending and damage under the effects of vibration and impact, and can play a role in corrosion resistance for a long time.
Further, in this embodiment, the top of the blind hole 4 has an internal thread for installing a thermometer, and the thermometer generally has an external thread structure, so that the thermometer can be screwed into the blind hole 4. The blind hole 4 in this embodiment may be a cylindrical hole or a stepped hole, and its shape is designed adaptively according to the shape of the thermometer. For example, if the diameter of the external thread of the thermometer is larger than the diameter of the thermometer body extending into the blind hole 4, the blind hole 4 is configured as a stepped hole adapted to the shape of the thermometer.
In this embodiment, the connecting flange 1 and the sleeve body may be integrally formed, but the integral forming process is complex, and preferably, the integral forming process is formed by adopting a welding process.
In the embodiment, the sleeve body comprises a cylindrical section 2 and a conical section 3 which are adjacently connected, and the connecting flange 1 is welded with the cylindrical section 2; the cylindrical section 2 has a preformed section above the connecting flange 1.
In the embodiment, the sleeve body is made of 304 steel, the cost of the 304 steel is low, and the manufacturing cost of the thermometer protective sleeve can be reduced while the structural strength is ensured. However, those skilled in the art may choose different materials for different media in the pipe or vessel, such as 316L, 2205, 904 and other suitable materials for the materials that can be upgraded for the highly corrosive or hazardous media to prevent damage to the tetrafluoro layer. The anticorrosive layer is made of polytetrafluoroethylene material.
In the embodiment, the end face and the side face of the bottom end of the conical section 3 are in fillet transition connection, so that the impact of fluid on the bottom end of the conical section 3 is further reduced.
Further, in this embodiment, the length of the conical section 3 is 280mm to 320mm, the diameter of the top end is 30mm to 35mm, and the diameter of the bottom end is 15mm to 25mm. Of course, the person skilled in the art can reasonably design the dimensions of the conical section 3 according to the actual circumstances.
The adaptation to the actual need is within the scope of the utility model.
It should be noted that it will be apparent to those skilled in the art that the present utility model is not limited to the details of the above-described exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
