Description

Floating ball valve is filled in one kind
Technical field
The utility model, which is related in valve field, more particularly to one kind, fills floating ball valve.
Background technology
Ball valve plays connection and Truncation in industrial pipeline, it is desirable to when blocking, and spheroid front and back end must not have leakage existing As.The spheroid of floating ball valve in ball valve is to float, and under pressure medium effect, spheroid can produce certain displacement and press On the sealing surface of the port of export, it is ensured that the port of export is sealed.Simple in construction, the good airproof performance of float ball valve, according to mounting means Difference, ball valve is divided into upper-mounting type ball valve and side-mounted ball valve, compared with side-mounted ball valve, upper-mounting type ball valve have reduce leak outside Point, reduces the advantages such as influence of the pipe stress to flange in valve, while the maintenance that upper-mounting type ball valve may be implemented on pipeline, tears open Unload simple rapid, it is easy to maintenance quick, maintenance time is greatlyd save, the loss in production is preferably minimized.But, it is existing on When filling the closing of floating ball valve spheroid, if medium pressure itself is relatively low, possibly can not provide enough sealing forces ensures sealing, draws Play leakage.
The content of the invention
In order to solve the above problems, it is novel, good sealing effect upper that the purpose of this utility model is to provide a kind of structure Fill floating ball valve.
In order to realize above-mentioned purpose, the utility model employs following technical scheme:
Floating ball valve is filled in one kind, it is characterised in that:Including valve body, and the spheroid being positioned in valve body, and it is fixed Bonnet on valve body, and the valve rod being located on bonnet;The valve body is provided with the medium entrance on same axis And media outlet, the inner end of medium entrance and media outlet, which is provided between tilted block, two pieces of tilted blocks, forms upper end open Greatly, valve seat is fixed with the small valve pocket of lower ending opening, the inclined end face of tilted block;The spheroid is arranged in valve pocket, valve rod Inner end is connected with spheroid;The sphere of spheroid and the sealing surface of valve seat, which are tilted, to be coordinated, and spheroid is provided with and axially penetrates through its body Medium runner, medium entrance, media outlet and medium runner be in same level on.
Preferably, axis specular of the two pieces of tilted blocks along valve rod.
Preferably, the bonnet is fixed on valve pocket accent, stuffing-box is provided with the valve pocket on the inside of bonnet, valve rod is worn In stuffing-box;It is provided between the valve rod and stuffing-box on filler, stuffing-box and is fixed with the gland for positioning the filler.
The utility model uses above-mentioned technical proposal, and the technical scheme, which is related in one kind, fills floating ball valve, the floating ball valve In medium entrance and the inner end of media outlet be provided with tilted block, valve seat is fixed on the inclined end face of tilted block, spheroid Tilt and coordinate with valve seat, ball seat sealing is coordinated using cone angle, easily sealing.Specifically, in ball valve closed mode, medium punching Ball beating body, inclined-plane wedging between spheroid stress and downstream valve seat, sealing effectiveness is more preferable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail.
Floating ball valve, including valve body 1, and the spheroid 2, Yi Jigu being positioned in valve body 1 are filled in one kind as shown in Figure 1 It is scheduled on the bonnet 3 on valve body 1, and the valve rod 4 being located on bonnet 3.The valve body 1 is provided with Jie on same axis The inner end of matter import 11 and media outlet 12, medium entrance 11 and media outlet 12 is provided with tilted block 13, tilted block 13 Flat end face is relative with the inner end of medium entrance 11 or media outlet 12 to be connect, and joint is sealed provided with sealing ring, The sealing ring can be O-ring seals.
The valve pocket 14 that upper end open is big, lower ending opening is small is formed between two pieces of tilted blocks 13.The bonnet 3 is fixed on On the accent of valve pocket 14, stuffing-box 31 is provided with the valve pocket 14 of the inner side of bonnet 3, valve rod 4 is located in stuffing-box 31, and valve rod 4 is with filling out It is provided between material letter 31 on filler 32, stuffing-box 31 and is fixed with the gland 33 for positioning the filler, specifically gland 33 can be connected by screw on stuffing-box 31;Using above-mentioned filling-material structure, sealing surface has worn and torn valve later by long-term use, Spheroid 2 and valve seat can be made to reach that new cooperation position realizes sealing again, valve is extended and use the longevity by on-line control screw Life.
The inner end of the valve rod 4 is connected with spheroid 2, axis specular of two pieces of tilted blocks 13 along valve rod 4.It is described Valve seat 5 is fixed with the inclined end face of tilted block 13, spheroid 2 is arranged in valve pocket 14;The sphere of spheroid 2 and the sealing of valve seat 5 Face, which is tilted, to be coordinated, and spheroid 2 is provided with the medium runner 21 for axially penetrating through its body, medium entrance 11, media outlet 12 and medium Runner 21 is in same level.During installation, the outer end of valve rod 4 can connect driving part, and driving part can need people The handle of work manual actuation, the outer end of valve rod 4 can pass through threeway sleeve connection handle;Driving part can also drive automatically Rotary cylinder, the outer end of valve rod 4 can connect rotary cylinder by shaft coupling.In use, driving part drives spheroid by valve rod 4 2 are rotated, when the medium entrance 11, medium runner 21 and media outlet 12 are sequentially communicated, and valve is opened;When on spheroid 2 When medium runner 21 is not communicated with medium entrance 11, media outlet 12, valve is closed.
The utility model uses above-mentioned technical proposal, and the technical scheme, which is related in one kind, fills floating ball valve, the floating ball valve In medium entrance 11 and the inner end of media outlet 12 be provided with tilted block 13, valve seat 5 is fixed on the beveled end of tilted block 13 On face, spheroid 2 is tilted with valve seat 5 to be coordinated, and ball seat sealing is coordinated using cone angle, easily sealing.Specifically, shape is closed in ball valve During state, media impingement spheroid 2, inclined-plane wedging between the stress of spheroid 2 and downstream valve seat 5, sealing effectiveness is more preferable.
