Abstract
The utility model belongs to a conveniently installed thermocouple consisting of a terminal box, a protective sleeve and a temperature metering element. The protective sleeve is formed by coaxially mounting an upper protective sleeve and a lower protective sleeve from top to bottom, the upper end of the upper protective sleeve is fixedly installed on the terminal box, the temperature metering element is coaxially arranged in the protective sleeve and the upper end of the temperature metering element is fixedly installed on the terminal box, wherein the lower end of the upper protective sleeveand the upper end of the lower protective sleeve are coaxially installed by an adjustable nut. The conveniently installed thermocouple has simple structure, scientific and rational design, convenientinstallation and detachment, short construction time, lower maintenance cost and good sealing performance, and the utility model relates to a conveniently installed thermocouple with higher safety.
Description
Technical field
The utility model belongs to the thermopair in the temperature sensor field, especially a kind of civilian dress thermopair.
Background technology
Thermopair is one of temperature sensor of using always; thermopair in the temperature sensor adopts the product of the anti-formula of shaking of armouring more; the form that all adopts last protective casing and following protective casing to be separated on the structure; the lower end of last protective casing adopts thread forms to be connected with the upper end of following protective casing; when installing at the scene; can will descend protective casing to be installed on the equipment earlier, will go up protective casing again and partly insert down protective casing and utilize screw thread to screw to get final product.Though this structure can realize that the connection between the protective casing cooperates up and down, still there are the following problems: 1. the electric Way out of terminal box can not be adjusted arbitrarily, the inconvenient field erected situation of final direction can occur; 2. upper and lower protective casing utilizes screw thread to carry out installation and removal, when small product size is big, or goes up protective casing weight when heavier, and operation is inconvenience extremely, influences work efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of civilian dress thermopair is provided, and this thermopair is easy for installation, and the engineering time is short, and the maintenance maintenance cost is lower, good seal performance, and security is higher.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of civilian dress thermopair; constitute by terminal box, protective casing and temperature element; protective casing reaches down by last protective casing, and the upper and lower coaxial installation of protective casing forms; last protective casing upper end is packed on the terminal box; coaxial the placing in the protective casing and on it of temperature element is packed on the terminal box, wherein goes up the lower end of protective casing and installs by active locknut with the upper end of following protective casing is coaxial.
And, between protective casing on the active locknut position and following protective casing, an O-ring seal is installed.
And described terminal box is anti-explosion terminal box or waterproof junction box.
And described temperature element is the armouring temperature element.
Advantage of the present utility model and beneficial effect are:
1. the last protective casing lower end of this civilian dress thermopair installs by active locknut and following protective casing upper end; seal by O-ring seal between last protective casing and the following protective casing; this kind structure makes things convenient for the installation of thermopair; can adjust the electric Way out of terminal box arbitrarily; maintenance maintenance is time saving and energy saving; good seal performance has effectively improved security.
2. the terminal box of this civilian dress thermopair is anti-explosion terminal box or waterproof junction box, prevents that effectively measured medium is excessive, improves security.
3. the utility model is simple in structure, and design science is reasonable, installation, convenient disassembly, and the engineering time is short, and the maintenance maintenance cost is lower, and good seal performance is the higher civilian dress thermopair of a kind of security.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of civilian dress thermopair; by terminal box 1; protective casing and temperature element 7 constitute; terminal box is anti-explosion terminal box or waterproof junction box; present embodiment is an anti-explosion terminal box; protective casing is by on last protective casing 2 and the following protective casing 6; coaxial installation forms down; last protective casing upper end is packed on the terminal box; be fixed with flange 5 on the following protective casing; conveniently be connected with tested cylinder body or container; coaxial the placing in the protective casing and on it of temperature element is packed on the terminal box; temperature element is the armouring temperature element; wherein go up the lower end of protective casing and install by active locknut 3, between protective casing on the active locknut position and following protective casing, seal by O-ring seal 4 with the upper end of following protective casing is coaxial.
The utility model when mounted; the following protective casing that will have flange earlier installs on the tested cylinder body; then temperature element and the terminal box that connects is connected to down on the protective casing by active locknut; this civilian dress thermopair connection finishes; in use, when temperature element damages, only need to go up that protective casing outwards winding is replaceable temperature element; time saving and energy saving, reduced the cost of maintenance maintenance.
Claims (4)
1. civilian dress thermopair; constitute by terminal box, protective casing and temperature element; protective casing reaches down by last protective casing, and the upper and lower coaxial installation of protective casing forms; last protective casing upper end is packed on the terminal box; coaxial the placing in the protective casing and on it of temperature element is packed on the terminal box, it is characterized in that: install by active locknut with the upper end of following protective casing is coaxial the lower end of going up protective casing.
