Abstract
The utility model discloses a kind of novel fluorine-lined single-seat adjusting valve, form primarily of valve body, spool, tetrafluoro bellows, valve gap, valve body stud, filler, filler pressing sleeve, hold-down grid and valve rod, described valve body neutral position is provided with on the upside of spool, valve body inner spool and is provided with tetrafluoro bellows, valve gap is provided with above valve body, on valve gap, the left and right sides is provided with valve body stud, valve rod connects spool through valve body and valve gap, above valve gap, valve rod both sides are provided with filler, filler is provided with filler pressing sleeve, and filler pressing sleeve is provided with hold-down grid.The utility model adopts telescoping structure regulating valve to open size, can make the advantages such as the utility model adjusting function is good, negotiability is large, applied widely.Because valve body adopts S shape runner design, make the pressure reduction of spool both sides little, media flow is stablized, thus reduces the erosion of medium to valve plug, sleeve surface, reduces the possibility of leaking further, improves the working life of product.
Description
Technical field
The utility model belongs to modulating valve technical field, is specifically related to a kind of novel fluorine-lined single-seat adjusting valve.
Background technique
At present, the conventional modulating valve of being able to bear strong corrosion of chemical industry adopts lining fluorine single-seat adjusting valve substantially, and valve body and internal materials adopt carbon steel lining tetrafluoro, structure primarily of Sealings such as valve body, spool, valve rod, valve gap, fillers and
Drive unit forms, and its working principle is according to site technique requirement, is changed the stroke of valve by accessory drive, thus realizes the flow of processing medium, pressure, temperature or the isoparametric control of liquid level.Due to the impact of single-seat adjusting valve unbalanced construction, make the unbalanced force suffered by spool large, the permissible pressure of valve is little, and the thrust of Suo Pei actuator is large, and cost is high; And lining fluorine single-seat valve spool and valve seat are the nonmetallic material such as lining tetrafluoro, its hardness is low, and sealing surface very easily weares and teares, and working life is extremely short; In addition because the particularity of modulating valve use occasion makes spool often be in the restriction vicinity work of valve, velocity of medium is high herein, large to spool face erosion, the adjusting function of valve is declined fast; Add the restriction of lining fluorine process engineering, the development of current temporary linerless fluorine sleeve adjusting valve, and serve as a contrast fluorine single-seat adjusting valve and be only applicable to pressure compared with low, that pressure reduction is little, bore is also less occasion; Again due to the structural limitations of lining fluorine modulating valve, make valve have the shortcomings such as negotiability is less than normal, degree of regulation is low, working life is short, the usage requirement of the operating modes such as high temperature, High Pressure Difference, heavy caliber, deep-etching cannot be met.
Model utility content
The purpose of this utility model is to provide a kind of novel fluorine-lined single-seat adjusting valve, to solve the deficiency existed in such scheme.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of novel fluorine-lined single-seat adjusting valve, form primarily of valve body, spool, tetrafluoro bellows, valve gap, valve body stud, filler, filler pressing sleeve, hold-down grid and valve rod, described valve body neutral position is provided with on the upside of spool, valve body inner spool and is provided with tetrafluoro bellows, valve gap is provided with above valve body, on valve gap, the left and right sides is provided with valve body stud, valve rod connects spool through valve body and valve gap, above valve gap, valve rod both sides are provided with filler, filler is provided with filler pressing sleeve, and filler pressing sleeve is provided with hold-down grid.
Described valve body stud is provided with hexagon nut.
Described valve body stud connects valve body through valve gap.
The utility model adopts telescoping structure regulating valve to open size, can make the advantages such as the utility model adjusting function is good, negotiability is large, applied widely.Because valve body adopts S shape runner design, make the pressure reduction of spool both sides little, media flow is stablized, thus reduce the erosion of medium to valve plug, sleeve surface, XDS special alloy ensure that with the valve material corrosion rate of medium contact minimum, the further possibility reducing leakage, improves the working life of product.
