Description
Technical field
The present invention relates to a kind of seal teflon valve, belong to Chemical Manufacture fluid flow control field, particularly relate to a kind of seal teflon valve controlling fluid flow.
Background technique
Material handled in chemical process is fluid mostly, generally includes liquids and gases in fluid.As in hydrometallurgy process, the beneficiating process carried out is in order to lean ore enrichment is obtained concentrate, and the fluid in beneficiating process is ore pulp, so usually can contain the solid particle of some in a liquid.In wet-process metallurgy, in order to obtain the metal in ore, according to ore heterogeneity, usual employing acid, alkali or the leaching of other solvents, useful metal is dissolved down from ore, thus reaches the object of recovery, therefore first leaching is carried out to ore and be necessary.In chemical process, the fluid of all flowings all needs to control, and one is control flow, and namely fluid flows by necessary requirement; Want control flow check direction of flow on the one hand in addition, namely make fluid import another direction from a direction on request.Therefore when fluid flows, the pipeline of conveying needs mounted valve, therefore valve acts in course of conveying is very important.
The kind of valve is diversified, can prepare on request.Industrially carried out large quantity research to material, when fluid uses strong acid media, material can use corrosion-resistant plastic, and Plastic valve extensive use.Greatest problem during Plastic valve uses is at a higher temperature, and valve can deform.Simultaneously Plastic valve is when applying, and because of Long-Time Service, rotations of regulating rotary axial length phase causes wearing and tearing to stuffing box packing, makes to regulate rotating shaft place to leak, and stainless steel can high temperature resistant, high pressure when manufacture valve, but not resistance to hydrochloric acid.For solving the control of current valve for high temperature, high pressure, deep-etching fluid, the present invention devises for this reason in conjunction with actual production technological requirement, the present invention devises a kind of seal teflon valve controlling fluid flow, this valve controllable flow body flow and possess good seal, valve can reduce the wearing and tearing of fluid to filler; In addition valve adopt parts processing, split car to go out and assemble simple, change convenient, decrease the waste to valve material, the fluid that the present invention is highly suitable in chemical process transmits.
Summary of the invention
The object of the present invention is to provide a kind of seal teflon valve controlling fluid flow, this valve comprises inlet passage, handle, valve outer cover, valve casing, spool, stretchability connector element, valve inner support and outlet passage; Valve outer cover is connected by screw and is fixed on inlet passage and outlet passage; Valve inner support is connected by screw and is fixed on inlet passage and outlet passage; Valve inner support is provided with tapered rod and stretchability connector element; Spool top is T-shaped round column structure and matches with valve casing inside, is conical head and matches with inlet passage bottom spool; Handle is connected with valve casing by threaded stem.The present invention mainly overcomes the not corrosion resistance of stainless steel, Plastic valve, and possesses feature that is high temperature resistant, high pressure.
For achieving the above object, the technical solution used in the present invention is a kind of seal teflon valve controlling fluid flow, when valve needs augmented flow, operator's handle with sleeve also drives valve casing to move up by threaded stem transmission, the bottom belt movable valve plug of valve casing moves up, stretchability connector element generation stretch texturing also drives tapered rod to move up, now tapered rod bottom controls the area of contact of itself and fluid inlet by conical head, thus reaches the object controlling fluid flow and increase; When valve needs to reduce flow, operator's handle with sleeve also drives valve casing to move down by threaded stem transmission, the top tape movable valve plug of valve casing moves down, stretchability connector element generation stretch texturing also drives tapered rod to move down, now tapered rod bottom controls the area of contact of itself and fluid inlet by conical head, thus reaches the object controlling fluid flow and reduce; Stretchability connector element and tapered rod and valve inner support as a whole, and stretchability connector element is male and fomale(M&F) structure.
Compared with prior art, the present invention has following beneficial effect.
1, the present invention adopts polytetrafluoroethylmaterial material to have high temperature resistant, high pressure, etch-proof advantage, and Applicable scope is large, Safety performance good, is highly suitable for the fluid transmission in chemical process.
2, whole valve is assembled simple and can be realized split replacing, decreases the waste of valve material.
3, each parts of the present invention adopt parts processing, decrease procedure and can change component at any time.
Accompanying drawing explanation
Fig. 1 is the seal teflon valve structural representation controlling fluid flow.
Embodiment
Below with reference to accompanying drawing, this experiment invention is described in further detail.
Be illustrated in figure 1 the seal teflon valve structural representation controlling fluid flow, this valve comprises inlet passage 1, handle 2, valve outer cover 3, valve casing 4, spool 5, stretchability connector element 6, valve inner support 7 and outlet passage 8; Valve outer cover 3 is connected by screw and is fixed on inlet passage 1 with on outlet passage 8; Valve inner support 7 is connected by screw and is fixed on inlet passage 1 with on outlet passage 8; Valve inner support 7 is provided with tapered rod and stretchability connector element 6; Spool 5 top is T-shaped round column structure and matches with valve casing 4 inside, is conical head and matches with inlet passage 1 bottom spool 5; Handle 2 is connected with valve casing 4 by threaded stem.The present invention mainly overcomes the not corrosion resistance of stainless steel, Plastic valve, and possesses feature that is high temperature resistant, high pressure.When valve needs augmented flow, operator's handle with sleeve 2 also drives valve casing 4 to move up by threaded stem transmission, the bottom belt movable valve plug 5 of valve casing 4 moves up, there is stretch texturing and drive tapered rod to move up in stretchability connector element 6, now tapered rod bottom controls the area of contact of itself and fluid inlet by conical head, thus reach the object controlling fluid flow and increase, realize the transmitting procedure of fluid from inlet passage 1 to outlet passage 2; When valve needs to reduce flow, operator's handle with sleeve 2 also drives valve casing 4 to move down by threaded stem transmission, the top tape movable valve plug 5 of valve casing 4 moves down, there is stretch texturing and drive tapered rod to move down in stretchability connector element 6, now tapered rod bottom controls the area of contact of itself and fluid inlet by conical head, thus reach the object controlling fluid flow and reduce, realize the transmission closing process of fluid from inlet passage 1 to outlet passage 2; Stretchability connector element 6 and tapered rod and valve inner support 7 as a whole, and stretchability connector element 6 is designed to male and fomale(M&F) structure, to improve stretch texturing and torque resistant ability.
