Abstract
The utility model relates to a kind of self-cleaning type to a point metal seal ball valve, this self-cleaning type comprises left valve barrel to a point metal seal ball valve, right valve barrel, spheroid, lower rotary shaft, valve rod, scraper function valve seat, preloading spring group, fire proof seal graphite, turbine final controlling element, O type circle and valve gap, described scraper function valve seat is to be designed to the spheric structure as scraper in the sealing surface both sides of valve seat, in the time that ball valve opens and closes, scraper function valve seat energy automatic scraping is except the foul being bonded on ball seal face, keep the clean of ball seal face, the utility model self-cleaning type can automated cleaning sphere foul when the valve opening and closing to point metal seal ball valve, make ball valve remain good sealability.
Description
Technical field
The utility model relates to valve technology field, specifically relates to a kind of self-cleaning type to a point metal seal ball valve.
Background technique
The common separable type metal seal ball valve of currently available technology is mainly made up of left valve barrel, right valve barrel, spheroid, lower rotary shaft, valve seat, cylindrical spring group, fire-protection ring, valve rod, Sealing and operating device, is mainly used in the medium operating modes such as the buck, Heisui River, mortar and the coal slurry that contain a large amount of solid grits.Fraction metal seal ball valve often there will be various sealing problems in operating mode using process; Chinese patent CN202451878U discloses a kind of separable type hard seal ball valve; improve the sealing effect of sealing pair, but still can not solve for the problem that affects sealability because of easily cementing medium coking on spheroid and valve seat, bonding.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, provides a kind of self-cleaning type to a point metal seal ball valve.The utility model self-cleaning type comprises left valve barrel to a point metal seal ball valve, right valve barrel, spheroid, lower rotary shaft, valve rod, scraper function valve seat, preloading spring group, fire proof seal graphite, turbine final controlling element, O type circle and valve gap, described scraper function valve seat is to be designed to the spheric structure as scraper in the sealing surface both sides of valve seat, when work, thereby rotate and drive spheroid to rotate by turbine final controlling element band ovable valve stem, the sealing of spheroid and valve seat relies on spring thrust to realize sealing function, in the time that ball valve opens and closes, scraper function valve seat energy automatic scraping is except the foul being bonded on ball seal face, keep the clean of ball seal face, make ball valve remain good sealability simultaneously.
The utility model beneficial effect is compared with prior art: adopt self-cleaning type scraper function valve seat, energy automated cleaning sphere foul and particle in the time of valve opening and closing; The medium operating modes such as valve seat two ends are provided with that fire proof seal graphite, sealing are reliable, long service life, the buck, Heisui River, mortar and the coal slurry that are applicable to contain a large amount of solid grits.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural drawing of the utility model scraper function valve seat.
Description of reference numerals: 1 is left valve barrel, 2 is right valve barrel, and 3 is spheroid, and 4 is lower rotary shaft, and 5 is valve rod, and 6 is scraper function valve seat, and 7 is cluster spring, and 8 is fire proof seal graphite, and 9 is turbine final controlling element, and 10 is O type circle, and 11 is valve gap.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1-2, above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of self-cleaning type comprises left valve barrel 1 to a point metal seal ball valve, right valve barrel 2, spheroid 3, lower rotary shaft 4, valve rod 5, scraper function valve seat 6, preloading spring group 7, fire proof seal graphite 8, turbine final controlling element 9, O type circle 10 and valve gap 11, described scraper function valve seat 6 is to be designed to the spheric structure as scraper in the sealing surface both sides of valve seat, when work, thereby being with ovable valve stem 5 to rotate by turbine final controlling element 9 drives spheroid 3 to rotate, the sealing of spheroid 3 and valve seat 6 relies on spring thrust to realize sealing function, in the time that ball valve opens and closes, scraper function valve seat 6 can remove the foul being bonded on spheroid 3 sealing surfaces by automatic scraping, keep the clean of ball seal face, make ball valve remain good sealability simultaneously.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
Claims (2)
1. a self-cleaning type comprises left valve barrel, right valve barrel, spheroid, lower rotary shaft, valve rod, preloading spring group, fire proof seal graphite, turbine final controlling element, O type circle and valve gap to a point metal seal ball valve, characterized by further comprising scraper function valve seat, described left valve barrel and right valve barrel connect as one, valve rod is connected with spheroid integrated design, lower rotary shaft is arranged on spheroid bottom, turbine final controlling element is connected with valve rod, scraper function valve seat is arranged on left and right valve inner, realizes sealing by preloading spring group, fire proof seal graphite and O type circle.
According to claim 1 a kind of self-cleaning type to a point metal seal ball valve, it is characterized in that described scraper function valve seat is to be designed to the spheric structure as scraper in the sealing surface both sides of valve seat, in the time that ball valve opens and closes, scraper function valve seat energy automatic scraping is except the foul being bonded on ball seal face, keep the clean of ball seal face, make ball valve remain good sealability simultaneously.
