Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the hydrophorce fitting seat of the present embodiment, comprise pipeline 1, on a side pipe wall 2 of pipeline 1, have perpendicular hole, the outer end of tube wall 2 is welded with lining 6, lining 6 middle parts have stepped hole, stepped hole increases from top to bottom gradually, is positioned at the first step place entrant sound sleeve pipe 5 is installed, and entrant sound sleeve pipe 5 tops extend in 2 perforates of tube wall, the complete tubulose of entrant sound sleeve pipe 5, the upper surface of entrant sound sleeve pipe 5 is concordant with the internal face of tube wall 2; Be positioned at the second step place seal block 7 is installed, the top and bottom of seal block 7 are respectively arranged with boss, boss place cover has an O type rubber ring 8, seal block 7 forms end face seal by an O type rubber ring 8 at upper and lower end boss place with lining 6, is positioned at the 3rd step place metal washer 9 and locking nut 10 are installed; Seal block 7, metal washer 9 and locking nut 10 middle parts all have hole, and hydrophorce 12 measuring ends are positioned in entrant sound sleeve pipe 5, and hydrophorce 12 fixed blocks are positioned in seal block 7.
The top that is positioned at the perforate of seal block 7 middle part institutes is provided with groove, and groove is installed the 2nd O type rubber ring 11, between the fixed block of seal block 7 and hydrophorce 12, by the 2nd O type rubber ring 11, forms end face seal.
Have a plurality of through holes 4 on the sidewall of entrant sound sleeve pipe 5, on the sidewall of entrant sound sleeve pipe 5 central positions, upper end, have exhaust port 3.
Hydrophorce 12 is the integral type structure.
The wall thickness of lining 6 is greater than 7mm.
In actual using process, the present invention is installed on to the hydrophorce measuring section in test specimen (pump, valve) import and outlet port.
In the as installed process, as shown in Figure 1, the fixed component of hydrophorce 12 puts after the 2nd O type rubber ring 11 in the seal block 7 of packing into; The outer wall upper and lower end step of seal block 7 all puts an O type rubber ring 8; By hydrophorce 12 lines, through metal washer 9 and locking nut 10, entrant sound sleeve pipe 5 is put in hydrophorce 12 ends; The entrant sound sleeve pipe 5, seal block 7, the metal washer 9 that install hydrophorce 12 are put into to lining 6 together with locking nut 10, adjust the position of each parts in lining 6; Finally locking nut 10 is tightened and got final product.
Working principle of the present invention is: the fluid in pipeline 1 flow in lining 6 cavity volumes through the through hole 4 of entrant sound sleeve pipe 5 outer walls, with the liquid in cavity volume, communicate, owing to forming sealing between seal block 7 and hydrophorce 12, lining 6, so the water in cavity volume is immobilising, gas in cavity volume can be discharged by the exhaust port 3 of entrant sound sleeve pipe 5 upper ends, and entrant sound sleeve pipe 5 upper ends flush with tube wall 2, can guarantee that runner is smooth, so do not affect the collection of underwater sound signal, reduced again the interference that aqueous medium flows and brings.Under normal pressure, be mainly that seal action is played in the axial seal formed between the rubber ring that carries of seal block 7 endoporus and hydrophorce 12 fixed blocks; But in the pressurization situation, a little less than axial seal effect, be mainly the groove on seal block 7 tops and the end face seal that hydrophorce 12 fixed blocks form by the 2nd O type rubber ring 11, and seal action is played in the end face seal formed between an O type rubber ring 8 at seal block upper and lower end boss place and lining 6.Form non-rigid the contact by two O type rubber rings between seal block 7 and hydrophorce 12 fixed blocks, reduced the impact of tube wall 2 vibrations on hydrophorce 12 signals collecting; Equally, at seal block 7 upper and lower end boss places, all overlap O type rubber ring arranged, make its with lining 6, metal washer 9 between for non-rigid the contact, secondary reduces the impact of tube wall 2 vibrations on hydrophorce 12 signals collecting.The underwater sound signal collected through hydrophorce 12 is input in computer through signal amplifier, multi-Channels Data Acquisition, is processed the hydrodynamic noise source special parameter that can obtain the piping elements such as pump, valve by the standing wave decomposition method.
Above description is explanation of the invention, is not that limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification to the restriction of invention.
