Abstract
The utility model relates to a kind of high-temperature hard sealing Flow-rate adjustment ball valve, comprises valve body, valve seat, valve rod, spheroid, valve gap, transmission device, Sealing and assembling set; Mainly spheroid channel entrance end is fan shaped borehole, and fan shaped borehole orthodrome end is towards the front end of spheroid opening direction, and spheroid channel outlet is the circular hole equal with valve channel; In the circular hole of spheroid channel outlet, install noise reduction screen, this noise reduction screen is along spheroid passage axis direction at right angle setting.By the cambered design of fan shaped borehole, make the circulation area of spheroid unit angle of swing equal, the Flow-rate adjustment linearity is good, is applicable to the flow control valve of high temperature media pipeline.
Description
Technical field
The utility model belongs to valve field, specifically about a kind of hard seal ball valve.The utility model is applicable to the flow control valve of high temperature media pipeline.
Background technique
Existing Flow-rate adjustment ball valve, general by valve body, valve seat, valve rod, valve gap, spheroid, transmission device, Sealing and assembling set, spheroid is shaped with the passage identical with valve body, transmission device rotation valve rod drives spheroid to rotate, realize the aperture of the unlatching of ball valve, closedown and control ball valve, reach the regulation and control to pipeline flow.Its major defect is spheroid is the circular hole passage of equal latus rectum with valve body, and spheroid identical angle of swing correspondence circulation flow is non-linear, Flow-rate adjustment poor linearity.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, provides the high-temperature hard sealing Flow-rate adjustment ball valve that a kind of Flow-rate adjustment linearity is good.
The technical solution of the utility model comprises valve body, valve seat, valve rod, spheroid, valve gap, transmission device, Sealing and assembling set; Mainly spheroid channel entrance end is fan shaped borehole, and fan shaped borehole orthodrome end is towards the front end of spheroid opening direction, and spheroid channel outlet is the circular hole equal with valve channel; In the circular hole of spheroid channel outlet, install noise reduction screen, this noise reduction screen is along spheroid passage axis direction at right angle setting.
In above technological scheme, adopt automatic compensation sealing filler between valve rod and valve gap, this automatic compensation sealing filler is made up of filler, Gland, disc spring, and disc spring is arranged in Gland upper-end surface by screw.
The utility model has the advantages that spheroid inlet passage is fan shaped borehole, by the cambered design of fan shaped borehole, make the circulation area of spheroid unit angle of swing equal, the Flow-rate adjustment linearity is good.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of spheroid in the utility model Fig. 1.
Fig. 3 is the structural representation installing noise reduction screen in the utility model Fig. 1 in spheroid circular hole.
Embodiment
High-temperature hard sealing Flow-rate adjustment ball valve as shown in Figure 1, comprises valve body 1, valve seat 2, valve rod 7, spheroid 3, valve gap 8, transmission device 6, Sealing and assembling set; Valve seat 2 adopts floating structure, designed by rational spring pre-tightening, not only ensure that the sealing force needed for low pressure but also the sealing force under automatically can regulating worst hot case, and prevented because temperature variation causes sealing force excessive, valve torque too increases and is even occurred by the phenomenon of locking; The surface of spheroid 3 and valve seat 2, by hardening process and abrasive process, meets shape metallic leak-proof structure antiscour at high temperature, anti-cavitation, abrasion resistance properties; Spheroid 3 channel entrance end is fan shaped borehole, fan shaped borehole orthodrome end is towards the front end of spheroid 3 opening direction, namely in spheroid 3 opening process, first orthodrome one end of fan shaped borehole touches the passage of valve body 1, the arc of fan shaped borehole adopts the design of computer finite element numerical analysis to determine, make the circulation area of spheroid 3 unit angle of swing equal, namely the angle of swing of spheroid 3 and the circulation area of its passage linear, spheroid 3 channel outlet is the circular hole equal with valve body 1 passage, as shown in Figure 2; Noise reduction screen 9 is installed in the circular hole of spheroid 3 channel outlet, this noise reduction screen 9 is along spheroid 3 passage axis direction at right angle setting, the direction that described at right angle setting is perpendicular to horizontal plane is installed, the some blocks of noise reduction screens 9 be parallel to each other are installed in spheroid 3 passage, eliminate medium enters circular hole generation noise from fan shaped borehole, as shown in Figure 3.Adopt automatic compensation sealing filler between valve rod 7 and valve gap 8, this automatic compensation sealing filler is made up of filler 4, Gland 10, disc spring 11, and disc spring 11 is arranged in Gland 10 upper-end surface by screw, carries out auto-compensation to the wearing and tearing of filler 4.Transmission device 6 is installed on valve gap 8 by support 12, and support 12 is installed thermal baffle 5, eliminates valve internal high temperature media to the impact of transmission device 6.
