Abstract
The utility model discloses a dust-proof fixed ball valve with the effects that dust can not enter spring cavities, and dirt and dust on sealing surfaces can be scraped off by a valve seat during the rotation, so as to greatly prolong the service life of a valve. The structure is mainly applied to fixed ball valves on the working conditions of solid particles or easily crystallized fluid. The main parts comprise a valve body (1), valve caps (2), a sphere (3), O-shaped rings (4), O-shaped rings (5), valve seats 6, valve seat support rings (7), springs (8), dustbands (9) and a valve rod (10), wherein stepped holes are processed in the valve body (1) and the valve caps (2); the dustbands (9), the valve seat support rings (7) and the valve seats (6) are mounted in the stepped holes in sequence; the springs (8) are arranged between the valve body (1) or the valve caps (2) and the bottoms of the valve seat support rings (7); and the O-shaped rings (4 and 5) are mounted in the grooves of the valve seats (6).
Description
One, technical field:
The utility model relates to fixedly spherical ball valve of a kind of anti-dust.
Two, background technique:
Along with the domestic economy fast development, also increasing for the demand of oil, the major part of oil source is import, and international oil price also goes up significantly, and for the consideration of national strategy, also needs to obtain the oil manufactured good from others.Under this background, domestic coal-to-oil industry is also important all the more.As various fluid control apparatuss, in coal-to-oil industry, need to use a large amount of fixedly spherical ball valves.At present, in coal-to-oil industry, owing to be with coal dust gasification again behind the chemical reaction, need originally to obtain the manufactured good that from oil, obtain, so in considerable line transportation, exist pulverized coal particle.The valve seat of common fixedly spherical ball valve and valve body, will be invaded from these slits after using a period of time dust under this operating mode because the needs of relative movement will exist some slight gap, cause preloading spring generation clamping stagnation; And on the other hand, the most valve seats that use and the sealing configuration of spheroid also can make dust or dirt enter sealing surface now, and these phenomenons all can make normally opening/closing of valve, and perhaps seal failure causes whole system to be stopped, and causes tremendous loss.
Three, summary of the invention
The purpose of this utility model provides fixedly spherical ball valve of a kind of anti-dust, and dust can not be entered in the spring chamber, and the dirt of sealing surfaces and dust can be struck off by valve seat in rotation process, and valve is improved working life greatly.This structure is mainly used in the fixedly spherical ball valve that has solid particle or easy crystallization fluid operating mode.Major part comprises: valve body (1), valve gap (2), spheroid (3), O type circle (4), O type circle (5), valve seat (6), valve seat support ring (7), spring (8), dust ring (9), valve rod (10).Valve body (1) and the interior processing step hole of valve gap (2), dust ring (9), valve seat support ring (7), valve seat (6) are installed in the step hole successively.Spring (8) is located between the bottom of valve body (1) (or valve gap (2)) and valve seat support ring (7), and O type circle (4) (5) is installed in the groove of valve seat (6).Spring (8) provides pretightening force, and pretightening force makes the sphere of spheroid (3) and the conical surface of valve seat (9) realize tangent sealing by the transmission of valve seat support ring (7).Between valve body (1) (valve gap (2)) and valve seat (6), process a cavity, put into thin slice that several compressible materials make in it as dust ring (9), eliminate the slit of valve seat (6) and valve body (1) (valve gap (2)), so just can stop that the dust in the fluid enters spring (8) chamber.O type circle (4) (5) on the valve seat (6) also can stop that the dust the fluid enters spring (8) chamber from another direction simultaneously.So just guaranteed to provide the spring (8) of pretightening force can activity freely not by clamping stagnation.Valve seat (6) the O-ring conical surface is designed to the structure of a protrusion, valve body (1) (valve gap (2)) and spheroid (3) can be fitted tightly all the time, O-ring conical surface upper and lower end all has sharp-pointed wedge angle, can in spheroid (3) rotation process, strike off the dirt and the dust on spheroid (3) surface, just not have dirt and dust between the conical surface of the sphere of spheroid (3) and valve seat (9) and destroy sealing effect.
Four, description of drawings:
Fig. 1 is the fixedly structure principle chart of spherical ball valve of a kind of anti-dust.
Fig. 2 is the enlarged view at A place among Fig. 1.
Five, embodiment
Specifically introduce below in conjunction with accompanying drawing, in Fig. 1, Fig. 2, a kind of anti-dust fixedly structure of spherical ball valve is: valve body (1), valve gap (2), valve rod (3), O type circle (4), O type circle (5), valve seat (6), valve seat support ring (7), spring (8), dust ring (9), spheroid (10).Valve body (1) and the interior processing step hole of valve gap (2), dust ring (9), valve seat support ring (7), valve seat (6) are installed in the step hole successively; Spring (8) is located between the bottom of valve body (1) (or valve gap (2)) and valve seat support ring (7), and O type circle (4) (5) is installed in the groove of valve seat (6), and dust ring is the plastic-steel material; Spring (8) connects valve seat support ring (7), the tangent sealing of conical surface of the sphere of spheroid (10) and valve seat (9); Between valve body (1), valve gap (2) and valve seat (6), a cavity is arranged, thin slice that 3 compressible materials make is arranged in it, O type circle (4) (5) is arranged on the valve seat (6) as dust ring (9); Valve seat (6) the O-ring conical surface is the structure of a protrusion, and valve body (1), valve gap (2) are fitted with spheroid (10), and O-ring conical surface upper and lower end all has sharp-pointed wedge angle.
Claims (1)
1. the fixing spherical ball valve of an anti-dust is characterized in that: be provided with valve body (1), valve gap (2), spheroid (3), O type circle (4), O type circle (5), valve seat (6), valve seat support ring (7), spring (8), dust ring (9), valve rod (10); Valve body (1) and the interior processing step hole of valve gap (2), dust ring (9), valve seat support ring (7), valve seat (6) are fixed in the step hole successively; Spring (8) is located between the bottom of valve body (1) and valve seat support ring (7), and O type circle (4), (5) are fixed in the groove of valve seat (6), and dust ring is the plastic-steel material; Spring (8) connects valve seat support ring (7), the tangent sealing of conical surface of the sphere of spheroid (3) and valve seat (9); Between valve body (1), valve gap (2) and valve seat (6), a cavity is arranged, thin slice that 3 compressible materials make is arranged in it, O type circle (4) (5) is arranged on the valve seat (6) as dust ring (9); Valve seat (6) the O-ring conical surface is the structure of a protrusion, and valve body (1), valve gap (2) are fitted with spheroid (3), and O-ring conical surface upper and lower end all has sharp-pointed wedge angle.
