Description
Affiliated field
The utility model relates to a kind of High Temperature High Pressure angle valve.
Background technique
In the prior art, the valve seat and the valve body of general stop valve are connected as a single entity, and valve rod generally also is whole.From the structure of stop valve as can be seen, the parts of stop valve can be divided into nonabradable durable, as valve body, gland, handle etc.; And vulnerable part, as valve seat, valve rod, filler etc.Be to increase the wear resistance of valve seat, build-up wear-resistant alloy on valve seat normally, but this operation needs carry out in narrow space, and difficulty is very big.Pay valve seat and valve rod is material manufacturing of the same race when valve seal, the basic indifference of both hardness when switch valve, often has affine being stained with to hinder phenomenon, causes valve seat because wearing and tearing and interior leakage.It is, not only waste time and energy, and less economical if in case valve seat damage must be pulled down whole valve and change or repair.For this reason, the vulnerable part of stop valve can be designed to the single parts of easy-off.
Chinese patent ZL96223858.9 discloses a kind of high temperature and high pressure cut-off valve, the sealing of this stop valve is paid and is spherical structure, be that flap adopts the cemented carbide spheroid, for line contacts, seal pressure is big between flap and the valve seat, good seal performance, especially be under pressure when washing away when valve, the flap that hydraulic type connects can be pushed revolution, makes and affords impact force on the sphere more equably, slowed down wearing and tearing on the whole, improved the working life of valve sphere.Adopt hydraulic pressure technology that the valve rod blind hole is closed up, be with the spheroid flap to be unlikely and drop, but can not tighten, can be used for 22MPa pressure, be lower than 570 ℃ operating mode occasion.Its valve seat is a built-up welding widia on valve body, and difficulty of processing is big, and as valve seat damage, whole valve body must be changed, and is less economical.
Chinese patent ZL01144441.X discloses the stop valve of a kind of replaceable valve seat and flap, the valve seat that employing is inlaid with the abrasion resistance alloy grommet is threaded on the valve body, removable flap top is cylindrical, has outside thread, the middle part is a square body, the bottom is a half sphere shape, and hemisphere is outer to be high temperature high voltage resistant and the anti-abrasion resistance alloy that washes away, and this flap is contained in the stem lower portion with internal thread.Because valve seat is installed on the valve body must be by means of special tool, and valve seat is connected with valve body with screw thread, because accuracy of screw machining is difficult for assurance, the sealing between valve seat and flap caused certain influence, processes, installation difficulty is relatively large.
Summary of the invention
The purpose of this utility model provides a kind of High Temperature High Pressure angle valve, and adopt and be designed to replaceable valve seat and flap, and the spherical ball structure, having reduced difficulty of processing, cost of production reduces, and is easy to maintenance, good economy performance.
The utility model is to realize like this.
High Temperature High Pressure angle valve of the present utility model mainly comprises valve body, valve seat, flap, valve rod, gland, filler, handle etc., the valve seat of being made by high-abrasive material is installed in the valve body, valve seat is lined with stainless steel gasket up and down respectively, be connected with valve body with internal thread on the valve body by the outside thread on the joint, screw screw thread valve seat and pad tightly are fixed on the valve body, in valve seat and the joint fluid passage is arranged.Valve seat is to be made by high-abrasive material, and described high-abrasive material is cemented carbide, Tungsten carbite and aluminium oxide, perhaps the alloy steel material of surface carburization or carburizing.
Valve rod is made up of upper valve rod and lower valve rod, the lower valve rod lower end is a flap, the upper end is a ball recess, the upper valve rod lower end also is a ball recess, upper valve rod is connected semi-ring with lower valve rod by two and spherical ball connects into whole valve rod, and two connection semi-rings close up in the ball recess that makes spherical ball place upper valve rod and lower valve rod, on the outer side surface of connection semi-ring Baltimore groove are arranged, Baltimore groove is embedded with anchoring filament, and Baltimore groove can have 2～4.Utilize concave groove and groove to be embedded with the fixing of anchoring filament, upper and lower valve rod is fused, be convenient to install.The material of anchoring filament is stainless steel or carbon steel or copper.
The refractory seal group is installed between valve body and valve rod, is respectively support ring, stuffing box packing and pressure ring from the bottom to top, and gland nut compresses stuffing box packing by pressure ring, makes valve stem seal.Stuffing box packing can be selected graphite, carbon fiber etc. for use, can anti-high temperature more than 400 ℃.The compaction degree of gland nut adjustable sealing filler keeps valve not leak outside.
Gland is fixed on the valve body by screw thread, and the outside thread of upper valve rod is connected with the gland upper internal threaded, the handle on the rotation upper valve rod, and valve rod moves up and down, and makes valve opening and closing.Owing between upper valve rod and lower valve rod, designed the spherical ball structure, make and act on the adjustment of the used power of upper valve rod by spherical ball on the axis of lower valve rod, thereby guaranteed that the flap head contacts with the valve seat endoporus equably, potted line evenly distributes, and has improved sealability.The material of lower valve rod, flap can be selected stainless steel, High Chrome Steel, carbon steel etc. for use according to the corrosivity difference of the medium of being carried, its material is different from valve seat, the hardness of flap material should be lower than the hardness of valve seat material, make the sealing surface hardness of flap and valve seat that one difference be arranged, reduce the probability of affine damage.
The gland bottom is fixed by internal thread and valve body outside thread, and gland nut is connected with gland by outside thread, regulates gland nut by the window that open on gland top, compresses the elevated-temperature seal filler by pressure ring, and valve stem seal is not leaked.
Valve is connected with pipeline, can be connected with pipeline with the Tube to tube fittings screw thread by the joint screw thread on the valve body, also screwed flange can be screwed on the joint, connect by flange, and screwed flange can adjust connecting direction, and is easy to operate.
If valve seat damage is pulled down joint, can change valve seat easily.The replacing of flap also only need be pulled down valve gap, and valve rod, flap, connection semi-ring are together pulled down, and unclamps the anchoring filament that connects in the semi-ring Baltimore groove, also conveniently replaced flap.
High Temperature High Pressure angle valve of the present utility model compared with prior art has the following advantages:
One, High Temperature High Pressure angle valve of the present utility model adopts the design of replaceable valve seat and flap, and is rational in infrastructure, behind the valve invalidation, do not need the integral replacing valve, only needs transposing part easily damaged parts get final product, and install, dismantle simple, easy to maintenance, good economy performance.
Two, the utility model adopts the structural design that connects semi-ring and spherical ball, has reduced the difficulty of processing of valve member, and processing technology is simple, and validity guarantees that easily cost of production descends.
Three, valve seat of the present utility model, valve body and flap material are selected rational Match, as steel and copper, steel and cemented carbide etc., make the sealing surface difference of hardness be tending towards rationally, have reduced affine damage phenomenon, have prolonged the working life of valve.
