Abstract
The utility model discloses a kind of seal connection, belong to engineering element or field of components.Comprise connected element and heat-exchange working medium coil pipe, heat-exchange working medium coil pipe is fixedly connected with connected element, connected element upper end is threaded connection and is provided with the first attaching nut, heat-exchange working medium coil pipe lower end is threaded connection and is provided with the second attaching nut, heat-exchange working medium coil pipe is plugged on connected element, and is fixed by the second attaching nut.The utility model is applied in the connection of heat-exchange working medium coil pipe and heat accumulation casing or blind flange, has the advantage of good leak tightness, safe and reliable, long service life.
Description
Technical field
The utility model belongs to a kind of fastening or fixed component, specifically, particularly relates to a kind of seal connection.
Background technique
At present, the Placement of heat-exchange working medium coil pipe and heat accumulation casing or blind flange is all realized by welding, i.e. punching on heat accumulation casing or blind flange, is first welded on water nozzle on heat accumulation casing or blind flange, to insert in water nozzle in heat-exchange working medium coil pipe and weld again, there is the welding of two places in total.There is following problem with the mode of being tightly connected of heat accumulation casing or blind flange in existing heat-exchange working medium coil pipe: 1, sealing problem: heat-exchange working medium coil pipe is connected with heat accumulation casing or blind flange, and heat-exchange working medium easily produces leakage at high-voltage operation; 2, Welding Problems: existing seal connection exists heat-exchange working medium coil pipe and welds with two places between heat accumulation casing or blind flange with water nozzle, water nozzle, weld quality of parent material changes, be in for a long time in press-bearing water tank, mother metal welding part is easily corroded, working life shortens, and often occurs the problem such as coil pipe and the leakage of flange mouth welding part.
Summary of the invention
The utility model object is to provide a kind of seal connection, to overcome the not good defect be easily corroded with weld of seal connection sealing in prior art.
The utility model realizes by the following technical solutions:
A kind of seal connection, comprise connected element and heat-exchange working medium coil pipe, heat-exchange working medium coil pipe is fixedly connected with connected element, connected element upper end is threaded connection and is provided with the first attaching nut, heat-exchange working medium coil pipe lower end is threaded connection and is provided with the second attaching nut, heat-exchange working medium coil pipe is plugged on connected element, and is fixed by the second attaching nut.
The pad with tapering is provided with between heat-exchange working medium coil pipe and connected element.
First attaching nut is respectively equipped with seal ring fixed groove, is provided with O-ring seals in seal ring fixed groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model is connected on heat accumulation casing or blind flange, good leak tightness, and there is not any welding in whole process, improve working efficiency, reduce cost of labor, there is not the risk destroyed by quality of parent material in Placement, therefore safe and reliable, working life is extended.

In figure: 1, connected element; 2, the first attaching nut; 3, O-ring seals; 4, body is connected; 5, the second attaching nut; 6, pad; 7, heat-exchange working medium coil pipe; 8, blind flange; 9, seal connection; 10, heat accumulation casing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of seal connection, comprise connected element 1 and heat-exchange working medium coil pipe 7, it is inner that heat-exchange working medium coil pipe 7 is plugged on connected element 1, and it is fastening by the second attaching nut 5 with connected element 1, heat-exchange working medium coil pipe 7 and connected element 1 joint are provided with the pad 6 with tapering, and pad 6 is red copper pad preferably, makes its joint No leakage at elevated pressures; First attaching nut 2 and connected element 1 are respectively equipped with seal ring fixed groove, are provided with O-ring seals 3 in seal ring fixed groove, make its joint No leakage at elevated pressures.
As shown in Figure 3, Figure 4, the utility model connects body 4 can be blind flange 8 or heat accumulation casing 10.
When the utility model uses, heat-exchange working medium coil pipe 7 is inserted in connected element 1, by the second attaching nut 5 and the special pad 6 with tapering, heat-exchange working medium coil pipe 7 fixing and locking is sealed, body 4 punching will be connected again, by connected element 1 through connecting body 4, by the first attaching nut 2 by fastening for its pressing, in seal ring fixed groove, O-ring seals 3 is installed, by the first attaching nut 2 and the second attaching nut 5 by connected element 1 be connected body 4 lock sealing, make its under high pressure No leakage.
