Abstract

The utility model relates to a temperature measurement field, which is a temperature measuring element for temperature measurement of the constant pressure medium of contacted oil and water in a thermal control system. The utility model is characterized in that the top and bottom ends of a fixing head 1 are provided with external screw threads, and the external screw thread is cooperated with a master device; the inner of an upper end hole is provided with a sealing component; the upper end of the seal component 2 is provided with a press plug 3; the upper part and the surroundings of the press plug 3 are provided witha press cap 4 with screw threads; the internal screw thread of the press cap 4 is matched with the external screw thread at the upper end of the fixing head 1. The utility model adopts a seal assembly sheathed on a protective pipe in series, thus, has the advantages of reliable sealing performance, flexible and adjustable length, visible seepage proofing performance and no oil and water leakage, and the utility model can work under the pressure of 1.5 Mpa for a long time.

Description

The adjustable temperature element of leakproof

The utility model relates to the temperature survey field, is a kind of temperature element, is used for the temperature survey of heat control system contact profit equal pressure medium.

At present, the temperature element that uses in this field is series such as CW2 and WRE, its whole device by: draw joint, resistance and leak rubber, temperature element head, element, terminal box and form.

During use, the temperature element head is inserted in the thermometric object hole, links to each other with temperature measurer in terminal box with resistance leakage rubber through drawing joint by element, carry out temperature survey, and be fixed on the main equipment outer wall by drawing being threaded of joint, in use, there is following weak point in this device:

1. when use installing, must earlier element head be inserted in the thermometer hole of main equipment, will draw joint again and twist and be connected on the equipment outer wall screw, twist in the termination process at screw thread, element and then rotates, and usually causes stubborn bad element.Because length can't be aligned, unnecessary can only roll into a ball in the equipment of staying, and therefore easily causes and is ground away.

2. to leak rubber not withstand voltage and easily aging in resistance, with draw between the joint can the generation gap, causes the profit seepage at element.And initiation fire hidden danger thus.

The purpose of this utility model provide a kind of element length adjustable and with the fit string cover of seal group, on element, form reliable sealing and fixing, reach the purpose of reliably anti-profit equal pressure medium seepage.

The purpose of this utility model reaches by following measures: fixed head 1, seal 2, tamponade 3, pressure cap 4 are enclosed within on the armour formula pillar 7 with withstand voltage pad 5 strings, are sealed by another seal 6 between armour formula pillar 7 and the element 10.Tighten fixed head 1 and compress withstand voltage pad 5, make fixed head 1 external thread obtain sealing, tightening pressure cap 4 again forces tamponade to move down compressive seal 2, make and obtain sealing between armour formula pillar 7 and the fixed head 1, owing to be vertical depression all, thereby guaranteed that element 10 is not rotated, and reached the purpose that prevents profit equal pressure medium seepage.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the utility model structural representation.

In Fig. 1, each parts name is called: 1. fixed head, 2. seal, 3. tamponade, 4. pressure cap, 5. withstand voltage pad, 6. another seal, 7. armour formula pillar, 8. temperature element head, 9. terminal box, 10. element

Now describe concrete structure of the present utility model in conjunction with the accompanying drawings in detail.

As shown in Figure 1, fixed head 1, seal 2, tamponade 3, pressure cap 4, withstand voltage pad 5, another seal 6, string are enclosed within on the armour formula pillar 7, and armour formula pillar 7 upper ends connect terminal box 9, and lower end communication member 10 is joined with temperature element head 8.It is characterized in that: the upper and lower side of fixed head 1 is provided with external thread, the lower end screw thread matches with main equipment, seal 2 is housed in the upper end hole, tamponade 3 is equipped with in the upper end of seal 2, tapped pressure cap 4 is equipped with around reaching in the top of tamponade 3, and the internal thread of pressure cap 4 cooperates with the external thread of fixed head 1 upper end.

During use, earlier with in the point for measuring temperature in temperature element head 8 insertion apparatus, adjustable seal assembly is transferred to correct position with leement duration on demand, and withstand voltage pad 5 put into main equipment outer wall screw seat, tighten fixed head 1 and compress withstand voltage pad 5, make and obtain sealing between fixed head 1 and the main equipment, seal between another seal 6 and the element 10, so as long as tighten pressure cap 4 again, force tamponade 3 vertical depression, compressive seal 2 makes between fixed head 1 and the armour formula pillar 7 to be sealed reliably, in this whole operation process, no any turning effort power so element 10 remains former state in equipment, can not be rotated damage on the element 10, join by terminal box 9 and thermometric display system, reach safe and reliable thermometric purpose.

The utlity model has following advantage: 1. owing to adopt gland 1, seal 2, tamponade 3, pressure cap 4 to form sealing The combine component string is enclosed within on the armour formula pillar 7, and therefore easy to use, length is flexibly adjustable. 2. owing to adopted seal assembly Anti-leakage structure, so leakage performance improves greatly. Experiment showed, that the utility model can be for a long time under 1.5Mpa pressure Work. The medium seepages such as no profit.
