The high-pressure multi-point flexible thermocouple is also provided with multiple leakproof structures, and is suitable for measuring the internal temperature of a high-pressure reactor.
Description
Technical field
The present invention relates to a kind of multipoint thermocouple, relate in particular to a kind of high-tension multipoint flexible thermopair with leak-checking apparatus, be 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, the fast response time of also measuring because of needs so can not make form with well, needs to adopt flexible thermocouple.The general required thermocouple temperature measurement of reactor thermometric is counted more than 3 points, counts 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, such 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 occur to leak, after long-time leakage, cause easily near the personnel of leakage point to poison, even may cause the security incident of burning or blast.
Summary of the invention
Technical matters to be solved by this invention is: a kind of high-tension multipoint flexible thermopair with leak-checking apparatus is provided, leaks and can't in time find easily the problem of leakage point to solve existing thermopair.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of high-tension multipoint flexible thermopair with leak-checking apparatus, comprise branched armoured thermocouple, 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 present invention is: described branched armoured thermocouple is fixed by reinforced tube and flange respectively, branched armoured thermocouple pass through reinforced tube and with reinforced tube two ends welding, the reinforced tube two ends again with flange welding.
The upper end of described upper connecting tube is provided with pullover greatly, the cold junction of branched armoured thermocouple by the multiply compensating wire gather large pullover in and with the rubber seal dress, pulloverly place in the cutting ferrule screw and be fixedly connected with upper connecting tube with the cutting ferrule screw greatly, 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 processed 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 present invention has following beneficial effect: 1, because lower pipe joint place is connected to valve and tensimeter, when valve is in opening, as pressure is arranged in the tensimeter, illustrate that there is leakage at the flange welding place, if select the tensimeter with remote transmission function, the pressure alarm point can also be set, just can in time find in the pulpit, but valve-off reaches again prevention leakage after defining pressure.2, branched armoured thermocouple and reinforced tube two ends welding; weld reinforcement Guan Zaiyu flange welding; 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, branched armoured thermocouple by lower pipe joint after before the brazing sheet soldering process, can effectively play the three-layer sealed effect.4, the multiply compensating wire of branched armoured thermocouple gather one large pullover in and with rubber seal dress, be connected with upper pipe joint by the cutting ferrule screw, can play the four-layer seal effect.The present invention uses safety applicable to the thermometric of high-pressure reactor inside, and the anti-leak performance is good.
The invention will be further described below in conjunction with the drawings and the specific embodiments.
