Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of cold-trap.
Background technology
Cold-trap is a kind of conventional cooling device, is mainly used in adsorbed gas or trapping oil vapour.As shown in Figure 1, cold-trap comprises cylindrical shell 2 and end socket 1, in order conveniently to carry out installation and the maintenance of inner facility, end socket 1 is made to the dismountable structure of flange connect, in cylindrical shell 2, be provided with refrigerant coil pipe 3 or coiled pipe, refrigerant coil pipe 3 or coiled pipe all need to carry out monitoring temperature.Temperature sense head 4 needs to insert in refrigerant pipe, and thermometer boss 5 stretches out from be located at the thermometric outlet 21 end socket 1, and forms hermetically-sealed construction with 21 welding of thermometric outlet.
When cold-trap inner facility need to overhaul, because the refrigerant coil pipe 3 in cold-trap is heavy and be fixed on cylindrical shell 2 inside, can only block thermometric outlet 21 just can open end socket 1 and overhaul, and end socket 1 after resetting needs thermometric outlet 21 to carry out welded seal, conventionally need to adopt multi-layer sealed assembly, after this external welding, need sealing to carry out Check processing, these operations are very numerous and diverse, spended time and need workman to possess certain technology.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of cold-trap that conveniently carries out installation and the maintenance of inner facility is provided.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is:
A kind of cold-trap, the cylindrical shell that comprises end socket, temperature measurement component and upper end open, in described cylindrical shell, be provided with refrigerant coil pipe, described end socket removably seals and is installed on cylindrical shell, described temperature measurement component comprises temperature sense head, thermometer boss and thermometric line, described thermometer boss one end is located in refrigerant coil pipe, the other end is fixedly connected with cylindrical shell, and extend to the outside of cylindrical shell, described temperature sense head is located at the inner chamber that thermometer boss is arranged in refrigerant coil pipe one end, and described thermometric line stretches in thermometer boss and is connected with temperature sense head.
Further improvement as technique scheme:
Described cylindrical shell side is provided with thermometric outlet, and described thermometer boss and thermometric outlet are fixedly connected to form hermetically-sealed construction.
Thermometric outlet and barrel soldering form hermetically-sealed construction.
Described thermometer boss bending extends in refrigerant coil pipe.
The bending angle of described thermometer boss is α, and α is more than or equal to 90 °.
Described thermometric outlet is near the upper end open place of cylindrical shell.
Described temperature measurement component is provided with two covers, and symmetrical.
Compared with prior art, the utility model has the advantage of:
Cold-trap of the present utility model, temperature measurement component is installed on cylindrical shell, does not need to consider the problem of temperature measurement component in the time of need to dismantling end socket again, has facilitated the dismounting of end socket.In the utility model, thermometer boss bending extends in refrigerant coil pipe, and bending angle need be more than or equal to 90 °, and angle too small can cause temperature sense head can not by kink, enter into smoothly the inner chamber of thermometer boss.Cylindrical shell of the present utility model side is fixed with thermometric outlet, and thermometer boss is fixedly connected with thermometric outlet, has guaranteed the sealing of cylindrical shell.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Number in the figure explanation:
1, end socket; 2, cylindrical shell; 21, thermometric outlet; 3, refrigerant coil pipe; 4, temperature sense head; 5, thermometer boss; 6, thermometric line.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further described.
Fig. 2 shows a kind of embodiment of cold-trap of the present utility model, comprise end socket 1, temperature measurement component and cylindrical shell 2, cylindrical shell 2 upper ends are provided with opening, are provided with refrigerant coil pipe 3 in cylindrical shell 2, end socket 1 removably seals and is installed on the opening of cylindrical shell 2, between end socket 1 and cylindrical shell 2, is provided with sealing ring.Temperature measurement component comprises temperature sense head 4, thermometer boss 5 and thermometric line 6, thermometer boss 5 one end are stretched in refrigerant coil pipe 3, the other end is fixedly connected with cylindrical shell 2, and extend to the outside of cylindrical shell 2, thermometer boss 5 is provided with the inner chamber that an end opening is sealed in one end, blind end is arranged in refrigerant coil pipe 3, temperature sense head 4 is located near in the inner chamber of blind end, thermometric line 6 one end connect control device, the other end stretches in the inner chamber of thermometer boss 5 and is connected with temperature sense head 4, and the temperature that temperature sense head 4 is surveyed passes to control device.Cold-trap of the present utility model, does not need to consider the problem of temperature measurement component again in the time of need to dismantling end socket 1, facilitated the dismounting of end socket 1, conveniently carries out installation and the maintenance of inner facility.
