Description
Technical field:
The utility model relates to the used protective device of petrochemical industry instrument, especially combination instrument heat insulation protecting case.
Background technology:
In petrochemical industry, various instrument are various, in order to protect the normal operation of instrument, especially at cold district, the heat insulation protecting device need be installed outside instrument.And instrument heat insulation protecting device influences ordinary production because reasons in structure exists to change and wastes time and energy, employs the problem that equipment is many, cost is high at present.
The utility model content:
Waste time and energy, employ the problem that equipment is many, cost is high in order to solve existing instrument heat insulation protecting device replacing; the utility model provides a kind of combination instrument heat insulation protecting case, this combination instrument heat insulation protecting case have change time saving and energy saving, do not employ equipment, characteristics that cost is low.
The technical solution of the utility model is: this combination instrument heat insulation protecting case comprises casing; casing is made up of preceding casing and rear box; preceding casing and rear box top and bottom are by the circular hole of being made up of semicircle; flanging in preceding casing and rear box contact position are oriented; preceding casing front is connected with the flanging top nut of rear box by screw; preceding casing and rear box contact position are equipped with sealing gasket, in preceding casing and the rear box heat-insulation layer are arranged, and there is door in preceding casing front.
The utlity model has following beneficial effect: this combination instrument heat insulation protecting case is owing to adopt the front and back double-body bike; utilize screw and nut to connect; without equipment cutting pipeline, thus the purpose that reaches quick replacing, significantly reduces labor intensity of operating staff, cuts pipeline, reduction replacement cost without equipment.Thus this combination instrument heat insulation protecting case have change time saving and energy saving, do not employ equipment, characteristics that cost is low.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is Fig. 1 vertical views;
Accompanying drawing 3 is that Figure 1A-A is to cut-open view.
Casing before the 1-among the figure, 2-rear box, 3-screw, 4-nut, 5-sealing gasket, 6-heat-insulation layer, 7-door, 8-circular hole.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings; this combination instrument heat insulation protecting case comprises casing; casing is made up of with rear box 2 preceding casing 1; preceding casing 1 and rear box 2 top and bottom are by the circular hole of being made up of semicircle 8; flanging in preceding casing 1 and rear box 2 contact positions are oriented, preceding casing 1 front is connected with the flanging top nut 4 of rear box 2 by screw 3, and preceding casing 1 is equipped with sealing gasket 5 with rear box 2 contact positions; in preceding casing 1 and the rear box 2 heat-insulation layer 6 is arranged, there is door 7 in preceding casing 1 front.
When reality is changed, rear box 2 is placed instrument and pipeline back, again preceding casing 1 is placed instrument and pipeline front, be connected with nut 4 with screw 3 then, promptly change and finish. because of preceding casing 1 and rear box 2 top and bottom respectively by the circular hole of forming by semicircle 8, so just need not cut off pipeline, thereby not need to employ equipment, only need can finish the replacing operation by a personal monkey wrench, the purpose that realize that finally replacing is time saving and energy saving, do not employ equipment, cost is low.
