Background technique
Dihedral septum valve be for modulating valve in high pressure or High Pressure Difference, have short, the product that serious problems develop such as valve rod easy-rupturing, lining easily come off of life-span under the severe service condition of serious cavitation, erosion.It adopts throttling form to share pressure reduction, decreases cavitation erosion, erosion, scratches stream destruction, substantially increase the working life of modulating valve.Valve body is right angle type, and spool is single guide structure, and valve body stream is simple, and resistance is little, is specially adapted to high viscosity, and the adjustment containing suspended matter and particle media fluid, can avoid coking, bonding, blocking.But existing angle type control valve is often because hydrodynamic pressure is excessive, antihypertensive effect is bad, produce cavitation and noise.
The Chinese patent patent No. is CN201420666027.X, disclose a kind of angle-style high pressure erosion resistance modulating valve, comprise driving mechanism, valve core rod, valve body, valve seat and bottom flange, wherein, described valve seat top is cylindrical shape, and offer multi-turn one-level decompression hole in the circumference of cylindrical shape part, seat bottom portion is provided with the liquid outlet being communicated with medium flow pass, described valve core rod one end is provided with and valve core rod one, and the keying section stretched in valve seat liquid outlet, big up and small down coniform of described keying section, have additional sleeve and orifice plate, described sleeve also cylindrically, and open at both ends, sleeve outer diameter is less than the internal diameter on valve seat top, valve seat top is placed in sleeve, sleeve wall is circumferentially with multi-turn secondary decompression hole, described orifice plate is between valve seat and bottom flange, described orifice plate is provided with the multiple three grades of decompression holes being communicated with liquid outlet and medium flow pass, the angle-style high pressure erosion resistance modulating valve of this structure, can only carry out twice step-down to the medium entering valve seat and spool, and protected effect is general, and the working life of valve seat and spool is general.
Model utility content
The purpose of this utility model is to provide a kind of erosion resistance modulating valve carrying out three grades of step-downs.
The technical solution of the utility model is: multilevel decompression erosion resistance modulating valve, comprise valve body, valve seat is provided with in valve body, valve seat is provided with spool, valve seat is provided with bag spool and is connected with valve rod, valve seat is provided with the three grades of decompression boards surrounding spool and valve rod, three grades of decompression boards are with secondary decompression board, valve body is connected with bonnet, valve rod is through bonnet, bottom flange is connected with under valve body, the side of valve body is connected with import valve body, medium entrance is had in import valve body, bottom flange is connected with outlet valve body, media outlet is had in outlet valve body, the track that medium flows to three grades of decompression boards from medium entrance is provided with one-level decompression board, one-level decompression board is provided with the first horn mouth near the side of medium entrance, the little nose circle of horn mouth is towards three grades of decompression boards.
Know-why of the present utility model and beneficial effect are: medium enters in import valve body from medium entrance, first will through the first horn mouth, first horn mouth is exactly the round platform of hollow, medium converges and enters in one-level decompression board by the first horn mouth, medium converge after, can make in media set by one-level decompression board, can avoid medium produce turbulent flow, reduce and the track upper inlet valve body of three grades of decompression boards or the erosion of valve body are flowed to medium entrance, also can reduce the erosion to one-level decompression board.
In media set by after one-level decompression board, will carry out first time step-down, then medium will enter into secondary by pressing plate, after secondary decompression board, medium will carry out second time step-down, and then medium will enter into three grades by pressing plate, after three grades of decompression boards, medium will carry out third time step-down; After three step-downs, pressure medium can be reduced in the scope of certain safety, last medium will contact valve seat and spool, by valve rod, spool is opened, to be entered in bottom flange by the space between valve seat and spool by the medium after step-down, through bottom flange, the media outlet from outlet valve body is flowed out.
Compared with prior art, on the one hand, during medium contact one-level decompression board, first can through the first horn mouth, the first horn mouth will reduce the turbulent flow of medium, thus reduces the erosion to valve body or import valve body and one-level decompression board; On the other hand, the modulating valve in present patent application, the medium that can be by convection into valve seat and spool carries out three step-downs, and what can be reduced by pressure further is less, thus reduces the erosion to valve seat and spool.
Further: the track that medium flows to media outlet from valve seat is provided with level Four decompression board, and level Four decompression board is provided with the second horn mouth near the side of media outlet, the little nose circle of the second horn mouth is towards bottom flange.Medium, from the inner process of whole valve, can carry out four step-downs, enter setting, medium can be made to drop to desirable value through four step-downs, can reduce the pressure suffered by each decompression board, extend the working life of each decompression board; Second bell-mouthed setting, can reduce the erosion of medium to valve body, bottom flange or outlet valve body, also can reduce the erosion of medium to level Four decompression board.
Further: one-level decompression board, secondary decompression board, three grades of decompression boards and level Four decompression board are circular orifice, and on circular orifice, circumference is evenly equipped with through hole.Medium can be made through one-level decompression board, secondary decompression board, three grades of decompression boards or level Four decompression board, the through hole uniform by circumference is uniformly distributed, equally distributed gas, and the pressure of all directions is all the same, make whole valve inner stressed more stable, reduce the damage to valve.
Further: between bonnet and valve body, between valve body and bottom flange, between valve body and import valve body, between bottom flange and outlet valve body, to be equipped with German-style metal lensring.High pressure pipe line widely uses seal with metal lens ring structure in connecting; The sealing surface of German-style metal lensring is sphere, contacts with the conical seal (contact) face of pipeline, and original state is a loop wire; Under pretightening force effect, German-style metal lensring produces plastic deformation in contacting point, and loop wire becomes endless belt, and sealability is better; Because surface of contact is by sphere and inclined-plane self-assembling formation, the easy centering of pad.
