in the figure: 1. a V-shaped bracket; 2. a hold-down bolt; 3. an adjusting plate; 4. the adjusting plate fixes the bolt; 5. the screw rod is connected with a long nut; 6. a screw rod; 7. a compression plate; 8. a water inlet pipe; 9. a tail pipe.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
in the figure: the utility model provides a novel stern tube tightness test device, includes V type support 1, regulating plate 3, inlet tube 8, its characterized in that: a tail pipe 9 is arranged on the V-shaped support 1, sealing gaskets are respectively bonded on two end faces of the tail pipe 9, pressing plates 7 are arranged on the outer sides of the sealing gaskets, adjusting plates 3 are respectively arranged outside the two pressing plates 7, and two pressing bolts 2 for tightly pressing the pressing plates 7 are horizontally arranged above and below the two adjusting plates 3; the two adjusting plates 3 are horizontally connected with a screw rod 6 above a tail pipe 9, and two adjusting plate fixing bolts 4 are respectively and vertically arranged on the top surfaces of the two adjusting plates 3; a screw rod lengthening nut 5 is arranged in the middle of a screw rod 6 between the two adjusting plates 3; a water inlet pipe 8 is also arranged on one of the compression plates 7. The adjusting plate 3 is arranged to be 7-shaped. The two adjusting plates 3 are oppositely arranged and connected together through a screw rod 6. And one end of the screw rod extension nut 5 is provided with a left thread, and the other end of the screw rod extension nut is provided with a right thread.
In specific implementation, the strength of the adjusting plates at two ends and the pressing plate needs to be considered to meet the requirement of the stern tube with the maximum specification diameter for the 0.2MPA tightness test, and the screw rod needs to be freely combined into different lengths according to stern tubes with different lengths by using screw rod extension nuts so as to meet the requirement of the stern tube tightness test. When the tail pipe is installed, the tail pipe is fixed on the V-shaped bracket, and sealing gaskets are bonded on two end faces of the tail pipe; lifting the left and right adjusting plates 3 to the two sides of the tail pipe, and propping the excircle of the tail pipe by four adjusting plate fixing bolts 4 to prevent the adjusting plates 3 from falling off; the screw rod penetrates into the adjusting plate, the length of the screw rod can be lengthened through a screw rod lengthening nut 5, and the screw rod is locked by nuts at two ends; locking the compression bolt 2 on the compression plate 7 to enable the compression plate 7 to tightly push against the end surface of the tail pipe; injecting water into the tail pipe through a water inlet pipe, connecting a manual pump, pressurizing to 0.2MPa, maintaining the pressure for 30min, and avoiding leakage. The utility model discloses conveniently solve the test work of stern tube tightness, improved the efficiency of tightness experiment, practiced thrift manufacturing cost, exerted very big effect for the preparation of boats and ships stern tube.
