Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; the adjustable armoured thermocouple of a kind of multipoint leakage resistance (resistance) is provided; this thermopair has been realized the measuring position of any adjusting temperature element in protective casing; and temperature element is changed convenient; measuring accuracy and security are higher; vibration resistance is better, and serviceable life is longer.
The present invention solves its technical matters and is achieved through the following technical solutions:
The adjustable armoured thermocouple of a kind of multipoint leakage resistance (resistance); constitute by terminal box, protective casing and temperature element; the upper end of protective casing is packed on the terminal box; temperature element is coaxial to be installed in the protective casing and its software line is packed on the terminal box; this temperature element lower end part leaks the sealing socket location and installation by resistance; wherein sealing socket is leaked by the coaxial installation of an active locknut with resistance in the lower end of protective casing, leaks the resistance neglected loading that compresses that temperature element is installed on the sealing socket in resistance and puts.
And described resistance is leaked sealing socket and is packed on the joint flange.
And, describedly compressing the resistance neglected loading and put by hold-down bolt, pressure pad and graphite grazing pad and constitute, temperature element passes the axle center of hold-down bolt, pressure pad and graphite grazing pad, and hold-down bolt leaks the sealing socket engagement with resistance and also compresses pressure pad and graphite grazing pad.
And the temperature element upper end in the described protective casing installs a high temperature joint, is filled with high-temp glue in this high temperature joint.
And described temperature element is the armouring temperature element, and its quantity is N and is packed on the resistance leakage sealing socket that the quantity of N is 2≤N≤24.
Advantage of the present invention and beneficial effect are:
1. the protective casing lower end of the adjustable armoured thermocouple of this multipoint leakage resistance (resistance) installs a resistance leakage sealing socket by an active locknut, and terminal box line outlet direction when mounted can be effectively adjusted in being provided with of this active locknut, makes the installation simple and fast.
2. the temperature element of the adjustable armoured thermocouple of this multipoint leakage resistance (resistance) is put and is fixed on resistance and leaks on the sealing socket by compressing the resistance neglected loading, compressing the resistance neglected loading puts by hold-down bolt, pressure pad and graphite grazing pad and constitutes, temperature element passes the axle center of hold-down bolt, pressure pad and graphite grazing pad, hold-down bolt leaks the sealing socket engagement and compresses pressure pad and graphite grazing pad with resistance, thereby fixing temperature element, this compress the resistance neglected loading put can prevent that temperature element from damaging after, deep-etching gas enters terminal box or enters external environment condition, effectively improves security.
3. the resistance neglected loading that compresses of the adjustable armoured thermocouple of this multipoint leakage resistance (resistance) is put with active locknut and is cooperated the length that can adjust temperature element, adapt to the actual demand of different station, even temperature element damages, as long as change temperature element, without integral replacing, saved the maintenance maintenance cost.
4. the upper end of the temperature element in the protective casing of the adjustable armoured thermocouple of this multipoint leakage resistance (resistance) installs a high temperature joint; can high-temp glue in this high temperature joint; when protective casing and temperature element are damaged; can effectively stop the corrosivity high-temperature medium to enter in the terminal box; prevent unexpected generation, effectively improve security.
5. the present invention has realized the measuring position of any adjusting temperature element in protective casing, and the temperature element replacing is convenient, and measuring accuracy and security are higher, and vibration resistance is better, and serviceable life is longer.
