Abstract
The utility model discloses a pipe joint assembly used for an auxiliary flushing and cooling system for a machine pump. The pipe joint assembly comprises a pipe head and a connecting pipe head. The rear end of the pipe head is provided with a tapered head, the outer wall of which is an arc surface. A front-end port portion of the connecting pipe head is a tapered port, in which the tapered head extends. The arc surface of the outer wall of the tapered head is in contact with the inner wall of the tapered port. Threads are respectively arranged on the outer wall at the rear end of the pipe head and the outer wall at the front end of the connecting pipe head and connected with nuts in a screwing mode. The pipe head and the connecting pipe head are connected via the nuts. The pipe joint assembly used for the auxiliary flushing and cooling system for the machine pump has following beneficial effects: the pipe joint assembly is reasonable in structure and excellent in sealing effect; sealing operation is achieved in such a manner that the arc surface of the outer wall of the tapered head is in contact with the inner wall of the tapered port; zero leakage is achieved; and problems including pipeline connection between a mechanical seal flushing and cooling system and a pump product auxiliary cooling system and inconvenient detachment are solved.
Description
Technical field
The utility model relates to the flushing of machine envelope and cooling system, high temperature pump series products auxiliary coolant system field, specifically a kind ofly rinses and cooling tube joint assembly for pump auxiliary system.
Background technique
Along with the development of pump industry, and pump should be in the complexity of the expansion in field and duty parameter, machine envelope is rinsed and cooling system is applied more and more frequent, particularly under the higher operating mode of medium temperature, thereby pump seat, pump cover and bearing support all need to access cooling water reduce pump temperature ensure working life, could facilitate maintenance but must dismantle auxiliary piping in the time that pump needs repairing, this was just need to be not only convenient connects auxiliary piping but also tube joint assembly for convenience detach meets use.
Model utility content
The purpose of this utility model is to provide a kind of for the flushing of pump auxiliary system and cooling tube joint assembly, solves current machine envelope flushing and cooling system, the connection of pump series products auxiliary coolant system pipeline and problem for convenience detach.
The technical solution of the utility model is as follows:
A kind of for the flushing of pump auxiliary system and cooling tube joint assembly, include tube head and be connected tube head, it is characterized in that: the rear end of described tube head has conical head, the outer wall of described conical head is arc shaped surface, the front end oral area of described connection tube head is taper mouth, described conical head extends in taper mouth, and the outer wall arc shaped surface of conical head contacts with the inwall of taper mouth; The outer wall of described tube head rear end be connected the outer wall of tube head front end on be respectively equipped with screw thread and be screwed with nut, described nut by tube head be connected tube head and link together.
Described rinses and cooling tube joint assembly for pump auxiliary system, it is characterized in that: the outer wall of described connection tube head rear end is provided with screw thread.
Described rinses and cooling tube joint assembly for pump auxiliary system, it is characterized in that: on the screw thread on described connection tube head front and back ends outer wall, be wound with respectively polytetrafluoro adhesive tape.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, outer wall arc shaped surface by conical head contacts to realize sealing with the inwall of taper mouth, sealing effect is very good, can reach zero leakage, has solved current machine envelope flushing and cooling system, the connection of pump series products auxiliary coolant system pipeline and problem for convenience detach.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of for the flushing of pump auxiliary system and cooling tube joint assembly, include tube head 1 and be connected tube head 3, the rear end of tube head 1 has conical head 4, the outer wall of conical head 4 is arc shaped surface, the front end oral area that connects tube head 3 is taper mouth 5, and conical head 4 extends in taper mouth 5, and the outer wall arc shaped surface of conical head 4 contacts with the inwall of taper mouth 5; The outer wall of tube head 1 rear end be connected the outer wall of tube head 3 front ends on be respectively equipped with screw thread and be screwed with nut 2, nut 2 by tube head 1 be connected tube head 3 and link together.
In the utility model, the outer wall that connects tube head 3 rear ends is provided with screw thread, is screwed into the part 6 that needs connection; Connect on the screw thread on tube head 3 front and back ends outer walls and be wound with respectively polytetrafluoro adhesive tape.
