Description
Technical Field
The utility model relates to a connection structure of closed cooling tower branch water collector and copper pipe belongs to closed cooling tower system technical field.
Background
The cooling tower is increasingly popularized in a central refrigeration air-conditioning system, and the structure and the service life of components of the cooling tower are one of important indexes for evaluating the performance of the cooling tower. The existing closed cooling tower water distributor-collector is connected with a copper pipe by a rubber flange, and the connecting structure can only bear lower working pressure and has low pressure-resistant grade. When the pressure of the circulating water rises, the copper pipe connecting structure may leak water or even be damaged.
SUMMERY OF THE UTILITY MODEL
For solving the defect that prior art exists, the utility model aims at providing a withstand voltage connection structure of higher closed cooling tower water collection and distribution ware of withstand voltage level and copper pipe.
The technical scheme of the utility model is that: the pressure-resistant connecting structure comprises a locking nut, wherein the copper pipe with a flared end is connected with the locking nut in a clamping sleeve manner, a sealing gasket is arranged at the flared end, the flared end is in sealing connection with a branch pipe of a water collecting and distributing device in the locking nut, and the branch pipe of the water collecting and distributing device is in threaded sealing connection with the locking nut.
The branch pipe of the water collecting and distributing device is in threaded sealing connection with the locking nut through the thread sealing of.
The raw material belt is a polytetrafluoroethylene raw material belt.
The sealing gasket is an annular sealing gasket, and the inner diameter of the annular sealing gasket is the same as that of the branch pipe of the water collecting and distributing device.
The outer diameter of the annular sealing gasket is larger than or equal to the outer diameter of the branch pipe of the water collecting and distributing device.
The utility model has the advantages that: the pressure-resistant grade can be improved, the parts are made of metal materials, the service life is longer, and the replacement frequency and the cost are reduced; the pressure resistance of the connecting structure is about 2.5 times that of the prior art; the connecting structure is easy to operate, the assembling time of the whole closed cooling tower can be reduced, and the assembling efficiency is improved.
Drawings
Fig. 1 is a usage state diagram of the present invention.
The reference numbers in the figures are as follows: 1. copper pipe, 2, seal gasket, 3, lock nut, 4, thread seal area, 5, branch pipe of water collector, 6, flared end.
Detailed Description
The present invention will be further explained with reference to fig. 1:
the utility model provides a withstand voltage connection structure of closed cooling tower water collection and distribution ware and copper pipe, includes lock nut 3, copper pipe 1 that has flaring end 6 with lock nut 3 cutting ferrule formula is connected, flaring end 6 department is equipped with seal gasket 2, and seal gasket 2 is annular seal gasket, annular seal gasket internal diameter is the same with branch pipe 5 internal diameter of branch water collection ware, and annular seal gasket external diameter is greater than or equal to branch pipe 5 external diameter of branch water collection ware, flaring end 6 with branch pipe 5 sealing connection of branch water collection ware in lock nut 3, branch pipe 5 of branch water collection ware is through the raw material area 4 and the 3 threaded seal of lock nut of winding on the external screw thread connection, raw material area 4 is polytetrafluoroethylene raw material area.
Before assembly, firstly, a locking nut 3 is sleeved on a copper pipe 1 in advance, then the copper pipe 1 is flared, and a sealing gasket 2 is placed; before the copper pipe 1 is connected with the branch pipe 5 of the water collecting and distributing device, the raw material belt 4 needs to be wound on the branch pipe 5 of the water collecting and distributing device, and the functions of reinforcing and sealing the connection part are achieved. When the locking nut 3 is screwed with the branch pipe 5 of the water collecting and distributing device, the front sealing gasket 2 of the copper pipe 1 is just matched with the branch pipe 5 of the water collecting and distributing device, so that pressure resistance can be guaranteed, and even if the pressure of a system is increased, water leakage at the connecting part of the copper pipe 1 can be avoided. In the closed cooling tower, the copper pipe 1 is connected with the branch pipe 5 of the water collecting and distributing device by adopting the cutting sleeve type connection mode, so that the pressure-resistant grade of the system can be enhanced, the service life of the connecting part is prolonged, and the cost is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
