Abstract
A high-pressure multi-point flexible thermocouple with a leak hunting device comprises a plurality of armored thermocouples, a junction box, an upper adapter, a lower adapter, and a flange. The lower adapter on the upper end of the flange is provided with a pressure gage. The pressure gage is connected with the lower adapter through a valve and a valve joint. The pressure gage can be employed for inspecting whether a welding site of the flange has leakage or not. The high-pressure multi-point flexible thermocouple is also provided with multiple leakage-proof structures and is applicable to internal temperature measurements of high-pressure reactors.
Description
Technical field
The utility model relates to a kind of multiple spot thermopair, relates in particular to a kind of high pressure multi-point flexibly thermopair that has leak-checking apparatus, is applicable to the inside thermometric of high-pressure reactor.
Background technology
A lot of reactors are arranged in the oil-refining chemical production run, its internal pressure is very high, and need the multi-step multi-point temperature measurement, the requirement of arranging because of singularity and the point for measuring temperature of inside reactor structure, need the thermopair use of going for a stroll, also fast because of the response speed of needs measurement, so can not make form with well, need to adopt the flexible thermal galvanic couple.The general required thermocouple temperature measurement of reactor thermometric is counted more than 3 points, counts more manyly when measurement, and the temperature of reactor monitoring is also more accurate.And reactor internal pressure is generally more than 3MPa, high pressure in addition reach more than the 10MPa, as the hydrocracking reactor in the oil refining apparatus, so the thermopair that needs can bear so high pressure, be again that multiple spot is not with sleeve pipe.
Reactor is except high pressure, the medium of the inside all is inflammable and explosive and is poisonous chemical substance, and height for reactor is also higher, thermopair also is to be contained in overhead tens meters high positions, also be difficult in time be found if take place to leak, after long-time leakage, cause near the personnel of leakage point to poison easily, even may cause the security incident of burning or blast.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of high pressure multi-point flexibly thermopair that has leak-checking apparatus, to solve the problem that existing thermopair leaked and can't in time find leakage point easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high pressure multi-point flexibly thermopair that has leak-checking apparatus, comprise many armoured thermocouples, terminal box, upper connecting tube, lower linking tube and flange, the lower linking tube place of described flange upper end is provided with tensimeter, and tensimeter is communicated with lower linking tube by valve and Valve joint.
The further technical scheme of the utility model is: described many armoured thermocouples are fixed by reinforcement pipe and flange respectively, and many armoured thermocouples pass through the welding of reinforcement Guan Bingyu reinforcement pipe two ends, and weld with flange at reinforcement pipe two ends again.
The upper end of described upper connecting tube is provided with pullover greatly, the cold junction of many armoured thermocouples by the multiply compensating wire gather big pullover in and with the glue encapsulation, big pullover placing in the cutting ferrule screw and with the cutting ferrule screw fixedlyed connected with upper connecting tube, upper connecting tube is threaded with terminal box.
Described upper connecting tube is by brazing sheet and lower linking tube welding, and the cold junction of armoured thermocouple is partly handled with the brazing sheet soldering by behind the lower linking tube.The lower flange face of described flange is welded with the thermocouple protection cover.
The utlity model has following beneficial effect: 1, because following pipe joint place is connected to valve and tensimeter, when valve is in opening, as pressure is arranged in the tensimeter, illustrate that the flange weld has leakage, if select the tensimeter with remote transmission function for use, the pressure alarm point can also be set, just can in time find in the pulpit, but valve-off reaches prevention leakage again after defining pressure.2, many armoured thermocouples and reinforcement pipe two ends welding; the welding of weld reinforcement Guan Zaiyu flange; can reduce the damage that welding causes thermopair by the welding of weld reinforcement pipe; the lower flange face of flange is welded with the thermocouple protection cover; protective cover can protect the weld of thermopair not to be destroyed, and can reach two-layer sealing effectiveness.3, many armoured thermocouples by behind the pipe joint down before brazing sheet soldering handle, can effectively play the three-layer sealed effect.4, the multiply compensating wire of many armoured thermocouples gather one big pullover in and with glue encapsulation, be connected with last pipe joint by the cutting ferrule screw, can play the four-layer seal effect.The utility model uses safety applicable to the thermometric of high-pressure reactor inside, and the anti-leak performance is good.
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
