The Kingston valve comprises a valve body, a valve disk, a valve rod, a packing seal device, a hand wheel mechanism and an inner support structure, wherein the inner support structure comprises three supports, the peaks of the supports are fixed together and end points of the supports are fixed at the lower end of the valve body; the peaks of the three supports are positioned at the centre of a circle of the water outlet of a kinston valve body; the first support is parallel to the water inlet of the kingston valve body, and the angle between the second support and the first support and the angle between the third angle and the first support are both 150 degrees. According to the invention, the inner support structure is embedded with the valve body into a whole, and the structure is simple, convenient to install and easy to realize. The noise of the flow field of the valve can be reduced on the basis that the stability of the original flow field is not damaged.
Description
Technical field
What the present invention relates to is the valve in a kind of vibration and noise reducing field.
Background technique
Along with the progress of development of science and technology with society; A large amount of fluid lines is applied to transfusion or gas transmission system; Pipeline transport has more and more important effect in the development of society; And in the middle of these engineering reality, valve is again indispensable important control, valve the direction of pipe-line system regulate and FLOW CONTROL in play an important role.Along with domestic and international valve technology rapid development, practical applications is also increasingly high to the quality requirement of valve.The hydraulic characteristic of valve is most important for instructing valve design.Yet in valve flowing channel, be accompanied by ubiquity turbulent flow, separation, air pocket, the flow phenomenon that water attack etc. are complicated, the valve noise also day by day becomes emphasis and the difficult point that people overcome.The noise of valve is diversified, mainly comprises mechanical noise, cavitation erosion noise, turbulent flow microseismic noise, eddy current crack and water hammer noise etc.For kingston valve, cavitation erosion noise, eddy current crack are the main sources of valve noise.The cavitation erosion noise be again the most common also be the most incidental.
Kingston valve is submarine internal duct system and the extraneous important device that is connected; Be mainly used in control and adjusting that each pipeline seawater injects and discharges; In the stealthy performance study of submarine; The vibration and noise reducing of kingston valve system is a crucial part, and the quality of its performance directly affects the noise level of each system and even whole ship.
Summary of the invention
The object of the present invention is to provide a kind of kingston valve that reduces valve cavitation erosion noise, eddy current crack, turbulent flow microseismic noise.
The objective of the invention is to realize like this:
A kind of kingston valve of the present invention; Comprise valve body, valve disc, valve rod, stuffing seal, handwheel; It is characterized in that: also comprise the inner support structure, described inner support structure comprises the support that three summits are fixed together, end points is fixed on valve body lower end, and the summit of three supports is positioned at the center of circle of kingston valve body water outlet; The axis of first support and kingston valve body water intake parallels, and second support all becomes 105 degree angles with the 3rd support and first support.
The present invention can also comprise:
When 1, the position of inner support structure in valve body guarantees that valve disc descends not with inner support structure connecting part.
2, the thickness of three of inner support structure supports is 5mm～10mm.
Advantage of the present invention is:
1. on valve body, press three supporting structures of fixed angle, can promote the minimum pressure of kingston valve inner flow passage, thereby more help preventing the generation of cavitation phenomenon.
2. on valve body, press three supporting structures that tilt fixing is installed, can make the velocity distribution of valve body lower end more even, make flow more steady, thereby reduced velocity gradient, reduced eddy current crack.
3. on valve body, press three supporting structures that tilt fixing is installed, can make runner smooth more, reduced the tubulence energy in the whole runner, thereby reduced the turbulent flow microseismic noise.
4. on valve body, press three supporting structures that tilt fixing is installed, can not only fundamentally reduce the noise of kingston valve, and this structure processing is simple, easy for installation.

Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～10, this valve is the right angle valve, and by Fig. 3,4 visible, kingston valve is in water outlet, and fluid in the valve body lower end velocity distribution serious biasing takes place, promptly at the subregional flow velocity of valve body lower end right-hand part obviously greater than the subregional flow velocity in left side.For the flow velocity equilibrium more that makes valve body lower end, and don't the high speed flow of obstruction right-hand member, so this patent installs fixed support additional in valve body lower end.Consider that support too much can influence area of passage, destroy the stability in original flow field, so adopted three supports.
Like Fig. 1, shown in 2; The area of passage that should guarantee right-hand member high speed flow zone is for maximum; Guarantee the left side mobile maintenance symmetry at two ends up and down again; Through taking all factors into consideration and confirm that through optimizing the back support in left side overlaps with the X axle, and two ends and X axle negative direction angle all are 105 ° about on the left of the support, and the angle of other two supports is 150 °.And according to 105 °, 150 °, 105 ° of fixed angles distribute between each support.
Fig. 5, the 6th, the Flow Field Distribution figure behind the valve body mounting bracket; Valve inner fluid speed does not have too big variation; But on the whole flow area of valve body lower end, serious speed biasing phenomenon originally takes a turn for the better to some extent, and three supports have played the effect of buffering, equilibrium velocity.
Fig. 7, the 8th, former valve and improvement valve central cross-section upward pressure distribution map from numerical value, can find out that the minimum pressure of former valve is 3.34MP, and the minimum pressure of new valve are 3.75MP, boost in pressure 13%.Improve minimum pressure, reduced the possibility that cavitation erosion takes place.
Fig. 9, the 10th, the tubulence energy figure on the inner flow passage central cross-section relatively can know, tubulence energy is by original 454m
2/ s
2Be reduced to 406m
2/ s
2, promptly after valve body was installed three fixed supports, tubulence energy reduced 11% in the runner, and the tubulence energy distribution is more even, explained that the flow field is smooth more, and flow velocity is balanced more.Tubulence energy has reduced, and corresponding turbulent flow microseismic noise will decrease, and is beneficial to the valve noise reduction.
The application passes through on valve body according to 105 °; 150 °; 105 ° of tilt fixings embed three fixed supports; To runner and The noise all is conspicuous, and not only is symmetrical on angle at two-part up and down that valve body lower end is divided into by support, on flowing, also is symmetrically distributed.
Can know that through above simulation result three fixed supports that on valve body, embed have good effect for reduction kingston valve cavitation noise, eddy current crack, turbulent flow microseismic noise.
