Abstract
The utility model discloses a bimetal thermometer used for measuring temperature in industry. The utility model is characterized in that a meter box and a meter cover are in thread engagement, glass on a meter surface and sealing rings are combined and arranged between the meter box and the meter cover, one end of a bending pipe is connected with a dial joint, the other end of the bending pipe is connected with a connecting piece of a temperature-sensing element, and a spring assembly with a rotation angle is arranged in the middle of the bending pipe, so that a meter head of the utility model has favorable sealing performance, and simultaneously, disassembly is convenient.
Description
The utility model relates to the instrument and meter for automation field, belongs to a kind of instrument that industrial measurement temperature is used specifically.
All there is poor sealing performance in domestic used various forms bimetallic system cell at present, especially under wet environment, can form steam in the watchcase, thereby cause the instrument square that contracts serviceable life, and influence its precision, and particularly the user often feels the matters of trouble, and the corner spring is exposed to very easily damage of outside simultaneously.
The purpose of this utility model provides a kind of not single gauge outfit good seal performance, can make dial plate and temperature-sensing element tear imperial bimetallic system cell arbitrarily open by bend pipe simultaneously.
For finishing the technical scheme that above-mentioned purpose is taked: for making the gauge outfit good seal performance, watchcase is screw-threaded engagement with the table lid, and watch crystal and O-ring seal combination are arranged between watchcase and the table lid.One end of bend pipe connects the dial plate joint, and the other end of bend pipe connects the temperature-sensing element web member, and the connection of above-mentioned bend pipe is and is threaded, and is convenient to tear open drive and install, and the corner spring assembly is put in the centre of bend pipe.
Gauge outfit of the present utility model adopts watchcase and table to cover screw-threaded engagement, the combination of watch crystal and O-ring seal is set in the middle of it, when threaded together seals owing to O-ring seal, make gauge outfit that excellent sealing performance be arranged, gauge outfit can not form steam in the watchcase under the high environment of humidity, gauge outfit is to be threaded by bend pipe with being connected of temperature-sensing element simultaneously, tear open and drive conveniently, be convenient to install, case and transportation.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1; watchcase 13 covers 16 with table and is screw-threaded engagement; watch crystal 15 and O-ring seal 17 combinations are arranged at watchcase 13 and show covers between 16; establish indicating hand component 12 and dial 14 in the watchcase 13; bend pipe 3 one ends connect dial plate joint 2; the other end of bend pipe 3 connects temperature-sensing element web member 5; put corner spring 4 in the middle of the bend pipe 3; gauge outfit is to be connected with temperature-sensing element by bend pipe 3; above-mentioned dial plate joint 2 is by set nut 11; nut 10; packing ring 1 connects watchcase 13; and above-mentioned temperature-sensing element web member 5 is by nut 6; packing ring 7 male connections 8; nipple 18 connects protection tube 9; temperature-sensing element 20 and steel wire 19 are set in the protection tube 9; one end of steel wire 19 connects temperature-sensing element 20, and the other end connects corner spring assembly 4.
When temperature-sensing element 20 is subjected to temperature influence just, temperature-sensing element is upheld or shortening, and promote or stretching corner springs by steel wire 19, make the pointer rotation, finish the effect of indication.
Claims (1)
