Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
With reference to shown in Fig. 1 to Fig. 4, a kind of connection structure for plate heat exchanger, including equipped with externally threaded public connection
Head, if female female connector, ring type seal.The end face of male connector is equipped with annular groove, and ring type seal is placed in
Annular groove, some exposes the end face of male connector to ring type seal, is conformed with the annular groove of male connector, i.e.,
The projection is arranged on the inner wall at annular groove, and ring type seal is equipped with notch, and it is close that the projection of male connector is caught in annular
In the notch of seal, the external screw thread of male connector and the internal thread of female connector carry out thread fitting, and male connector screws in female connect
In connector, it is in contact in female connector formed with step surface, ring type seal with the step surface of female connector.Female connector screws
After in male connector, the step surface of female connector presses ring type seal.
The projection on notch and male connector on ring type seal has a variety of setting forms, Yi Zhongshi：Ring type seal
On notch have multiple, be circumferentially uniformly distributed；The projection of male connector also have it is multiple, circumferentially uniformly point
Cloth.Another kind is：Notch on ring type seal is annular notch, and the projection in male connector is annular projection.Projection and lack
The cooperation of mouth, can guarantee that ring type seal is tightly stuck in annular groove.
Connection structure further includes seal rubber sleeve, and seal rubber sleeve is wrapped in the outside of male connector and the outside of female connector.
Seal rubber sleeve can be further ensured that male connector and the leakproofness of female connector, if while having gas or liquid leakage, a fluid sealant
Set can stick out.
Male connector is axially divided into external thread section, prominent conical section, pipe section.External thread section screws in female
In connector, annular groove is arranged on the end face of external thread section.Pipe section can be welded on plate heat exchanger.Prominent circular cone
On the one hand section can conveniently grip male connector, on the other hand, when pipe section is welded on plate heat exchanger, prominent conical section
Then tightly close to plate heat exchanger.
Female connector is axially equipped with internal thread hole and through hole, the friendship of female connector internal thread hole and through hole successively
Step surface is formed at boundary.As shown in Figure 1, when needing female connector to seal, then female connector is provided only with internal thread hole, no longer sets
Put through hole.
When female connector is equipped with through hole, the internal diameter of the through hole of male connector external thread section and the internal diameter of female connector through hole
