Abstract
The utility model discloses a full-spherical ceramic adjusting valve which relates to an adjusting valve. The full-spherical ceramic adjusting valve can resist corrosion from various strong corrosion media. A valve core, an adjusting element and a sealing part adopt ceramic material, thus the effects of durable and effective accurate adjustment and tight sealing of the adjusting valve can be achieved, the service life of the valve is prolonged, and the system operating mode is ensured to be operated safely and steadily. The full-spherical ceramic adjusting valve comprises the valve body, a ball body, a valve seat, the adjusting element and a transmission mechanism; an inlet is arranged at the left side of the valve body, an outlet is arranged at the right side of the valve body, the ball body presents a spherical shape, the ball body completely or partially adopts the ceramic material, and the adjusting element adopts the ceramic material. The full-spherical ceramic adjusting valve is used in chemical materiel pipelines.
Description
Technical field:
The present invention relates to a kind of modulating valve.A kind of regulating element is the ceramic modulating valve of global type.
Technical background:
Valve is a kind of device of controlling fluid motion.Modulating valve is a kind of device of controlling fluid flow or pressure.Comprise valve body, spool, regulating valve seat and driving mechanism; Main valve body is provided with import, and the side valve body is provided with outlet, and spool (throttle element) is set in the valve pocket, and spool is connected with driving mechanism.Regulating valve seat is installed in the valve outlet side, and the throttling window is set on the regulating valve seat.
When valve core sealed cover and sealing surface of seat disengaging, flowing medium promptly enters valve from import, flows out valve from outlet.When driving spool, driving mechanism action moves when the area of opening between spool and the regulating valve seat is reduced gradually, flowing medium is subjected to certain restriction by the flow of valve, the more little medium of the area of opening is more little by the flow of valve, when valve core sealed cover and regulating valve seat sealing surface fitted tightly, the valve closing medium was blocked.Drive spool when opposite direction is mobile when driving mechanism moves, the area of opening between spool and the regulating valve seat increases gradually, and flowing medium also increases gradually by the flow of valve, and when spool broke away from regulating valve seat fully, valve was opened fully.
When being between spool and the regulating valve seat when partially opening, medium constantly washes away the sealing surface of spool, regulating valve seat and throttling window and weares and teares, and especially has the medium of solid particle, washing away and wear and tear even more serious said elements.And present modulating valve, its sealing surface and throttle element generally are that metallic material is made, the anticorrosion and wear-resisting property of metallic material is relatively poor can't resist washing away, wear and tear and corroding the damage that causes spool and regulating valve seat of medium, makes the valve seal inefficacy.
Medium to regulating valve seat throttling window wash away and wearing and tearing cause the throttling window shape distortion to occur, thereby the flow that has influenced medium causes the valve flow characteristic curve to deform, system can't accurately regulate.
Strong corrosive media for chemical industry; most metallic material all can't be resisted the corrosion of medium; its valve body of present modulating valve, spool, throttle element are metallic material; so the position that the valve body of valve, sealing surface etc. contact with medium is corroded very soon and produces leakage, even produce the crisis people's that leaks outside life or befouling environment.Even there is the higher exotic material of a small amount of chemical stability can resist this corrosion, but, also can't be applied in the actual liter production because exotic material costs an arm and a leg.
Summary of the invention:
The present invention aims to provide a kind of global type spool.Spool, Sealing and throttling element are the novel modulating valve of pottery, and stupalith is installed in the valve body, and it can resist the erosion of various strong corrosive mediums.Spool, regulating element and Sealing adopt stupalith can realize lasting effectively accurate the adjusting and tight seal of modulating valve, prolong the working life of valve.Guarantee that system condition safely and steadily runs.
The present invention includes valve body, spheroid, valve seat, regulating element and driving mechanism; Left valve barrel is provided with import, and right valve barrel is provided with outlet, and spheroid is a global type, and spheroid is full pottery or part pottery, and regulating element is a pottery manufacturing.
Body cavity of the present invention can all be installed pottery also can be at import and outlet side or the local pottery of installing of valve body, and spheroid is a global type, and spheroid is full pottery or part pottery.
The regulating element of valve of the present invention can be that spheroid also can be a valve seat, and regulating element can be that bulk ceramics also can be the part pottery, and regulating element and Sealing can be that one also can be split.
Pottery of the present invention can be oxide ceramics, carbide ceramics, nitride ceramics.
Operation principles of the present invention is:
The area of opening between spheroid sphere and the regulating valve seat when the spheroid clockwise direction rotates reduces gradually, the rate-of flow that flows through valve reduces, when spheroid sphere and regulating valve seat were fitted fully, medium can't pass through valve export, and the present invention is buttoned-up status.
When spheroid counterclockwise rotates, the area of opening between spheroid sphere and the regulating valve seat increases gradually, flowing medium also increases gradually by the flow of valve, when the spheroid sphere breaks away from regulating valve seat when entering body cavity fully, the flowing medium that flows through valve is maximum, and the present invention is the complete opening state.
The present invention is provided with spheres of ceramic and ceramic regulating valve seat, pottery is installed in the valve body, pottery has the characteristic of hardness height, wear-resistant, corrosion-resistant, stable chemical performance, can resist washing away and corroding of flowing medium, guarantees the lasting effective seal of valve and stablizes accurate Flow-rate adjustment.
To sum up state describedly, the present invention is a kind of ceramic valve that can accurately regulate, and it can realize that the modulating valve sealing is tight, regulates accurately and can adapt to various strong corrosive medias, the working life of prolongation modulating valve.

Figure four closes top cross-sectional view fully for the present invention
Among the figure: 1-valve body, 2-spheroid, 3-valve seat, 4-driving mechanism, 5-import, 6-outlet, 7-pottery.
Embodiment:
With inside nominal diameter DN80mm, the present invention of nominal pressure PN1.0MPa is embodiment:
The present invention is used for the hydrochloric acid transporting system in chemical plant, the import and the outlet of valve body is installed in respectively on the hydrochloric acid conveyance conduit.The regulating valve seat of valve body adopts zirconia-based ceramics, and spool adopts the whole spheroid of full pottery, and body cavity is installed stupalith.
Under the present invention in off position, Korrosionsmedium enters valve pocket from import, and ceramic valve seat and spheroid sphere fit tightly, and valve export is in sealing state, and the pressure reduction between import and the outlet is 1.0MPa.When driving mechanism drive spheroid counterclockwise rotated, the spheroid passage was tending towards being communicated with valve channel gradually, and when both passages were communicated with fully, valve was in whole opening states, and medium can enter valve pocket from the valve body import, flows out from valve outlet.The rotation process of 90 ° of strokes of driving mechanism can be finished the present invention from closing, be adjusted to the overall process of unlatching.
The present invention has anticorrosion, wear-resisting, antiscour, sealing is tight, regulates accurately the characteristics such as long service life.
