Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.

The embodiment of the invention comprises the following steps: the structural schematic diagram of multi-functional pressure gauge installation device is shown in fig. 1 and fig. 2, including fixing base 1, oil pressure joint 2 and cover pressure joint 3, both ends at fixing base 1 are provided with female connector 4 and screwed joint 5 respectively, center at fixing base 1 is provided with the center overflow hole 6 that runs through, radial overflow hole 7 has been seted up symmetrically on fixing base 1's lateral wall, axial overflow hole 8 with radial overflow hole 7 intercommunication is seted up symmetrically in fixing base 1's lateral wall simultaneously, the oral area of crossing hole 8 all is provided with female connector hole 9 in two axial, threaded connection has oil pressure joint 2 and cover pressure joint 3 respectively on two female connector holes 9, the other end of oil pressure joint 2 and cover pressure joint 3 all with pressure gauge 10 threaded connection. Set up the radial test hole 12 with the center through-flow hole 6 intercommunication on the oil pressure connects 2, set up the first axial test hole 13 with radial test hole 12 intercommunication at the center that oil pressure connects 2, and the oral area of first axial test hole 13 contacts with the pressure sensing end of pressure gauge 10, the center that the cover pressure connects 3 is seted up the second axial test hole 11 with the axial through-flow hole 8 intercommunication, and the oral area of second axial test hole 11 contacts with the pressure sensing end of pressure gauge 10. And a sealing ring is arranged at the joint of the pressure gauge 10 and the oil pressure joint 2 or the sleeve pressure joint 3.

The working principle of the invention is as follows:

referring to fig. 3, during the use, connect pressure gauge 10 on fixing base 1, the user can dispose the quantity of pressure gauge 10 according to the test needs, can install two pressure gauges 10 simultaneously and test the internal pressure and the external pressure of oil pipe, also can install a pressure gauge 10 and test the internal pressure or the external pressure of oil pipe. When only one pressure gauge 10 needs to be connected, the other axial overflowing hole 8 in the fixed seat 1 can be plugged by a plug so as to isolate the pressure inside and outside the oil pipe.
