Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6 is please referred to, the present invention provides a kind of technical solution:
A kind of buffer medium adjusting flow V-type ball valve, including valve body 1,1 inner cavity of valve body are equipped with fluid channel, the fluid channel packet
Intake channel and exit passageway are included, the upper center of valve body 1 is equipped with stuffing-box, is equipped with filler 10, the material of filler 10 in stuffing-box
Matter is made of PTFE material, and the upper end of filler 10 is equipped with gland 12, and gland 12 is solid by adjusting bolt 11 and valve body 1
The inner cavity middle part of fixed connection, valve body 1 is equipped with the V-type sphere 8 between intake channel and exit passageway, leans in exit passageway
One end of nearly V-type sphere 8 is equipped with valve seat 4, and valve seat 4 is equipped with and 8 spherical seal surface shape of V-type sphere close to one end of V-type sphere 8
At the conical seal (contact) face of linear sealing, more preferably, valve seat 4 is connected with multiple springs 5 far from a side end face of V-type sphere 8 to sealing effect,
The valve seat preload ring 6 that multiple springs 5 are connect with the one end of exit passageway outwardly is connected, and the lateral wall of valve seat 4 circumferentially offers
Annular groove, fixing sleeve is connected to valve seat insert 7 in annular groove, and the lateral wall of valve seat insert 7 is circumferentially closely pasted with exit passageway
It closes, lift-off seal performance.
The side wall lower ends of the upper end side connection upper valve rod 9 of V-type sphere 8, the upper end of upper valve rod 9 passes through stuffing-box and reaches valve
The external connection handwheel (handwheel is not shown in the figure) of body 1, be located in stuffing-box one section of upper valve rod 9 are socketed with anti-wear gasket 16, subtract
Mill pad 16 is located at the lower end of filler 10, reduces abrasion, the sidewall upper of the lower end side connection lower valve rod 13 of V-type sphere 8, upper valve
The lower end of bar 9 connect the both ends of buffering strainer 2 with the upper end of lower valve rod 13, buffers in upper and lower ends and the V-type sphere 8 of strainer 2
The V-type face of side is connected, and increases structural stability, buffers and offers V-type medial surface flow direction on multiple and V-type sphere 8 on strainer 2
Consistent mainstream channel 17 buffers and is also provided with multiple tap holes 18 on strainer 2, and tap hole 18 and mainstream channel 17 are perpendicular
Distribution, decomposes impact of the different directions upper fluid medium to V-type sphere 8, and multiple tap holes 18 are in multiple mainstream channels 17
Matrix distribution, and the cross-sectional area of mainstream channel 17 is much larger than the cross-sectional area of tap hole 18.Mainstream channel 17 and tap hole 18
The shunting for realizing fluid media (medium) prevents the impact force of fluid media (medium) from influencing V-type sphere 8, the deformation of V-type sphere 8 is caused, thus shadow
The sealing effect of valve is rung, lower valve rod sleeve 15, the bottom wall of inner cavity company of lower valve rod sleeve 15 and valve body 1 are socketed on lower valve rod 13
It connects, is also equipped with lower cover 3 in the middle part of the lower end of valve body 1.
Above-mentioned component is combined into a kind of buffer medium flow adjusting V-type ball valve by assembling, when the valve is in the closed state,
The mainstream channel 17 and pipeline for buffering strainer 2 are into upright position state, and import medium can pass through multiple points on buffering strainer 2
Discharge orifice 18 carries out medium dispersion, and the medium that not will form one large area directly pushes V-type sphere 8 to, and V-type sphere 8 is caused to bear
Excessive pressure medium causes V-type sphere 8 deformation tendency problem occur, and buffering strainer 2 is rotated synchronously with V-type sphere 8,
When valve is in opening process, by the 18 medium peptizaiton of multiple tap holes on buffering strainer 2, unlatching moment will not be because being situated between
Matter impact is excessive, and when valve, which needs to open part, carries out flow adjusting, buffering 2 mainstream channel 17 of strainer is with pipeline into difference
Angle position state, due to medium flow through buffering strainer 2 on tap hole 18 and mainstream channel 17 changed, medium meeting
It is flowed directly out by the runner of unlatching, not will cause V-type sphere 8 when flow adjusts needs and opens half for a long time, a part
Sphere causes discontinuity that opening process irregularity, pause and transition in rhythm or melody, valve is caused to shake since medium effect is excessive, and V-type sphere 8
Problem on deformation caused by dividing edge pressure-bearing excessive.When valve reaches fully open position, 17 center of mainstream channel of buffering strainer 2 is
With pipeline at identical state, the problems such as will not influence flow velocity, the flow of medium.When the valve is closed, the rotation of V-type sphere 8 is closed
In the process, buffering strainer 2 by left hand material flow to, mitigate medium directly impact sphere cause open and close torque greatly, pause and transition in rhythm or melody, vibration
And sphere rim pressure large deformation problem, the effect of strainer 2 is buffered with being phase same-action during valve opening.It is above-mentioned to mention
A kind of buffer medium flow supplied, which adjusts V-type ball valve, to be had during valve opening and closing due to there is the presence of buffering strainer 2, and valve is made
Valve operation is smooth when door whole process opens and closes light torque, valves half open state, is not in pause and transition in rhythm or melody and vibration problems, not will lead to greatly
Area media directly impacts phenomena such as V-type sphere 8 deforms sphere unbalance stress.V-type sphere 8 equally has in opening-closing process
There are adjusting and shear action, extend the service life of equipment, the present invention has substantive distinguishing features outstanding and significant progress.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
