The utility model discloses have the multilayer protective properties, prolonged life, can change on line, satisfy the connection measurement to important temperature, need not stop work.
Description
Technical field
The utility model relates to temperature measuring equipment, the anti-temperature measuring head that washes away of particularly a kind of multi-stage protection.Be used to measure the temperature of high-speed motion granule medium.Temperature survey as equipment such as the riser in the catalytic cracking unit, reactor, catalyst regenerators.
Background technology
Because of the high-speed motion granule medium has very strong scouring force to thermometric protection tube and primary element, thereby protection tube and temperature element are washed away and damage.If high-temperature medium, this destructive power is bigger.
Summary of the invention
At present; the temperature of the anti-scour medium of domestic measurement; the general method that temperature element is protected with protection tube that all adopts; then, protection tube is plated the anti-alloy that washes away, in the insertion equipment; protection tube outside equipment adds stop valve; in case wash away leakage, just stop valve is cut off, guarantee that medium does not leak.The shortcoming of this method is: have only one deck protection, easily washed away leakage.Can't recover after washing away leakage, cause waste.Continuous coverage in the time of can not guaranteeing to measure the important temperature parameter.
The purpose of this utility model just provides the anti-temperature measuring head that washes away of a kind of multi-stage protection.
The technical solution of the utility model is: comprise temperature element; protection tube; mounting flange; terminal box; protection tube is divided into inner segment and outer section; each is connected with a mounting flange in its junction; being serially connected with ball valve temperature survey element on outer section of described protection tube is positioned at this protection tube and passes described ball valve; the outer end of protection tube is connected with terminal box; the outer end of temperature element is positioned at terminal box; there is the armouring pipe described temperature element outside; also be with intermediate casing outside the temperature element in the inner segment of protection tube; close in this intermediate casing appearance around one deck airduct; the upper end of this airduct causes protection tube outer section middle part and passes protection tube and is connected with gas-charging connection; section also is provided with stuffing-box outside the ball valve of section outside protection tube, and filler is arranged within it.
Being threaded by joint two ends between the outer section of described protection tube and the terminal box.
Armouring tube outer surface at described temperature element is coated with department's titanium Lay alloy-layer.
Described airduct is made by stainless steel.
The utlity model has the protective value of multilayer: after outermost protection tube is by erosion damage, that the airduct of the second layer and intermediate casing have is quiet, moving dual barrier effect, when airduct was washed away leakage, the gas ejection that is higher than pressure medium that charges within it was to moving particle starting barrier effect; The 3rd layer is the outer armouring pipe of temperature element; The 4th layer by packing seal and ball valve cut-out.The protective effect of multilayer had both prolonged serviceable life of the present utility model greatly; also can be after three-layer protection loses efficacy; moving protective effect by the 3rd layer makes granule medium can not enter protection tube; can extract temperature element like this out changes; realize online replacing; can satisfy the connection of important temperature is measured, need not quit work.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
Referring to Fig. 1; the utility model comprises armored temperature element 12, protection tube 8, mounting flange 9, terminal box 2; protection tube 8 is divided into inner segment and outer section; each is connected with a mounting flange 9 in its junction; temperature element 12 is positioned at the axle center of this protection tube 8; the outer end of protection tube 8 is connected with terminal box 2 by a joint 4, and the outer end of temperature element 12 is positioned at terminal box.Also be with intermediate casing 11 outside the temperature element 12 in the inner segment of protection tube 8; close in these intermediate casing 11 appearances around one deck airduct 10; the upper end 7 of this airduct 10 causes protection tube 8 outer section middle parts and passes protection tube 8 and is connected with gas-charging connection 6; outside protection tube 8, also be provided with stuffing-box 5 in the section, filler 51 is arranged within it.String has ball valve 13 on the protection tube 8 between stuffing-box 5 and the gas-charging connection 6.
Armouring tube outer surface at described temperature element 12 is coated with department's titanium Lay alloy-layer.
Described airduct 8 is made by stainless steel.
The utility model charges into the dry air or the nitrogen of certain pressure at its gas-charging connection 6 when work.The gas that is blown into must be that the medium of equipment is receptible, can not influence the operate as normal of equipment; The pressure of gas must be higher than the pressure in the equipment, and pressure reduction remains on 0.01-0.05Mpa; Gaseous tension is less than or equal to 0.6Mpa.
The utility model is because only need on the basis of existing temperature element in addition structural transformation, and simple in structure, cost is low, is easy to realize.
