Embodiment 1

[0032] see Figure 1-5 , the quick-connect connector of the disc-type valve operating device of the hydro-generator set, including a male connector 1 and a female connector 2, the end of the male connector 1 is provided with a first connecting nut 3, and the end of the female connector 2 is provided with a second connecting nut 5 , the inside of the first connecting nut 3 and the second connecting nut 5 are provided with a sealing washer 6; the surface of the male connector 1 is provided with an anti-slip buckle 4 at the connection point corresponding to the female connector 2, and the front end of the male connector 1 corresponds to The inner side of the anti-slip buckle 4 is provided with a connecting plate 7, the outer surface of the connecting plate 7 is provided with a through hole 8, the inner side of the through hole 8 is provided with a ball 9, and the outer surface of the connecting plate 7 is provided with a connecting plate 7 corresponding to the inner side of the an...

Embodiment 2

[0041] The installation method of the quick connection joint of the disc valve operating device of the hydroelectric generating set includes the following steps:

[0042] Step 1: Use the first connecting nut 3 to cooperate with the sealing washer 6 to install the male joint 1 on the matching flange surface of the disc valve;

[0043] Step 2: Use the second connecting nut 5 to cooperate with the sealing washer 6 to install the female joint 2 on one end of the mobile oil pump hose;

[0044] Step 3: Insert the female connector 2 into the inside of the male connector 1, and fasten the female connector 2 with the anti-slip buckle 4;

[0045] Step 4: Check the joint for oil leakage.

[0046] In the third step, during the plugging process, the anti-slip buckle 4 is first slid towards the rear end, so that the anti-slip buckle 4 compresses the first spring 11, so that the anti-slip buckle 4 slides along the surface of the connecting ring 10, and at this time the connecting plate 7 T...

Abstract

The invention provides a quick connecting joint for a disc valve operating device of a water-turbine generator set and a mounting method. A first connecting nut is arranged at the tail end of a male connector, a second connecting nut is arranged at the tail end of a female connector, and sealing washers are arranged in the first connecting nut and the second connecting nut; an anti-skid buckle is arranged on the surface,corresponding to the joint of the female connector, of the male connector, a connecting plate is arranged at the front end,corresponding to the inner side of the anti-skid buckle, of the male connector, a through hole is formed in the outer surface of the connecting plate, a ball is arranged on the inner side of the through hole, and a connecting ring is arranged on the outer surface,corresponding to the inner side of the anti-skid buckle, of the connecting plate. A first spring is arranged on the outer surface, corresponding to the side end of the connecting ring, of the connecting plate. A fixing ring is arranged on the outer surface of the front end of the female connector, and ejector rods are arranged on the inner side of the male connector and the inner side of the female connector. The problems that a traditional disc valve and an oil pump are inconvenient to disassemble, sealing performance is not enough after multiple times of disassembly, and oil leakage is prone to occurring are solved.

Description

technical field [0001] The invention relates to the field of a disc valve operating device of a hydroelectric generating set, in particular to a quick connection joint and an installation method of a disc valve operating device of a hydro generating set. Background technique [0002] During the operation of the disc valve of the hydro-generator set, temporary flanges and bolts are used to connect the mobile oil pump and the flange of the disc valve. When replacing the operating disc valve, the bolts and gaskets need to be disassembled, which is inconvenient for disassembly and assembly, and the work efficiency is low. Low; and after repeated disassembly and assembly, the sealing effect of the gasket becomes poor, and oil leakage often occurs due to improper sealing installation during connection. When the flange is removed, some residual oil will flow out from both ends of the flange, wasting oil and polluting the environment. Contents of the invention [0003] The purpose...
