Description
Technical field
The utility model relates to the valve production field, specifically a kind of axial flow single-seat adjusting valve.
Background technique
Single-seat adjusting valve of the prior art all adopts the zigzag valve body structure of low in and high out.On the one hand, MEDIA FLOW can produce vortex phenomenon at epicoele in the time of valve body, causes the radially concussion of spool and produces cavitation phenomenons, trim is caused wash away, thereby influence the adjusting function of life of valve and valve; Its two because the flow resistance coefficient of zigzag valve body structure is too big, make the flow coefficient of valve reduce, therefore, often need the valve of selecting bore bigger in the actual using process, user cost is higher; Moreover the valve noise is bigger, can't solve all the time.
Summary of the invention
Technical assignment of the present utility model is at above-mentioned the deficiencies in the prior art, and a kind of flow coefficient height, flow speed stability, the concrete better axial flow single-seat adjusting valve of noise reduction effect are provided.
Technical assignment of the present utility model is realized in the following manner: the axial flow single-seat adjusting valve, comprise valve body, the filler device assembly, valve rod, spool, valve seat and positioning disk, valve rod is arranged at the stuffing box place of valve body by the filler device assembly, valve seat is arranged at the feed pathway place of valve body, spool, positioning disk is arranged at valve inner, be characterized in: the feed pathway at valve body two ends, the coaxial setting of liquid outlet channel, valve rod is arranged on valve body near a side of liquid outlet channel by the filler device assembly, positioning disk is fixed in a side of close feed pathway in the valve body, the base portion of spool passes positioning disk and is in transmission connection by driving mechanism and valve rod bottom, and the movable end of spool is arranged at valve body feed pathway place and matches with valve seat.
In order to increase the noise reduction of modulating valve, can some isometrical noise reduction holes be set at positioning disk.
The diameter in noise reduction hole is preferably 6 ~ 8mm.
Described valve body preferably is made up of left valve barrel, right valve barrel, the liquid outlet channel of left valve barrel and the coaxial setting of the feed pathway of right valve barrel, positioning disk is fixed between left valve barrel and the right valve barrel, valve rod is fixed on the left valve barrel place by the filler device assembly, the base portion of spool passes positioning disk and is in transmission connection by driving mechanism and valve rod bottom, and the movable end of spool is arranged at right valve barrel feed pathway place and matches with valve seat.
Driving mechanism can be realized by various existing drive technologies, preferably, described driving mechanism comprises connecting rod, shift fork, alignment pin, alignment pin is fixed in left valve barrel inside, shift fork cooperates with the alignment pin rotation, the bearing pin of the intersection end of shift fork and spool base portion is connected, and the other end of shift fork is in transmission connection by connecting rod and valve rod bottom.
Axial flow single-seat adjusting valve of the present utility model compared with prior art has following outstanding beneficial effect:
(1) valve body structure is simple, and flow resistance coefficient is little, so flow coefficient is greatly improved, and makes optional valve aperture diminish, and has saved user cost greatly;
(2) feed pathway, the coaxial setting of liquid outlet channel, axial flow valve body structure avoided effectively eddy current formation, solved the problem of washing away, make velocity of medium more steady, the adjusting function of valve significantly improves;
(3) noise reduction formula positioning disk can reduce (having the noise reduction hole on the positioning disk) noise of valve effectively, has reduced noise pollution.
