Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of durable ball valve.
Background technique
Ball valve was come out the 1950's, and along with scientific and technical develop rapidly, updating of production technology and product structure, in the 40 short years, has developed rapidly and become a kind of main valve class.In the west flourishing country of industry, the use of ball valve is constantly risen year by year, in China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.It has the action of 90-degree rotation, and faucet body is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction that cuts off, distributes and change medium in pipeline, and it only need to just can be closed tightly by the operation of 90-degree rotation and very little moment of rotation.Ball valve optimum makees switch, cut-off valve uses, V-type ball valve.
But the diameter of existing universal standard ball valve be spheroid runner cross-sectional diameter 1.3-1.5 doubly, sphere size is less, and spheroid dams from standard-sized sheet to medium needs rotating sphere 70-75 angle, means the high moment of torsion of rotating sphere needs, rotate more effort, affect the working life of spheroid.
Model utility content
The utility model provides a kind of switch convenient durable ball valve, this ball valve adopts large-sized spheroid, only need 45-50 angle from standard-sized sheet to medium throttling at spheroid, the low strength of low moment of torsion is easily throttling just, reverse ball valve simple and fast more, because rotation angle is little, more can reduce the rotation of spheroid, reduce the loss of valve rod.
The purpose of this utility model reaches by the following technical programs:
A kind of durable ball valve, comprise valve rod, valve body, described valve rod is arranged on valve body top, in described valve body, be provided with valve seat and spheroid, in valve seat, be provided with spheroid, be provided with valve seat runner in valve seat, valve seat runner matches with the fluid course that valve seat two ends are connected, in spheroid, be provided with the spheroid runner matching with valve seat runner, the diameter of described spheroid be spheroid runner cross-sectional diameter 1.6-2.4 doubly.
Described valve body comprises left valve barrel and right valve barrel, is forging.
Described valve seat comprises valve seat A, valve seat middle part and valve seat B, and valve seat A, valve seat middle part and valve seat B are linked in sequence into a spherical hollow space solid forging that spheroid is installed.
Further, surface, the surface of spheroid runner and the surface of fluid course of described spheroid, both surfaces of valve seat, valve seat runner are equipped with nano-spray layer.
Between described fluid course and valve seat, be also provided with a round platform passage, large one end of round bottom face diameter of round platform passage is connected with valve seat.
Between described valve body and valve seat both sides, be provided with valve body liner.Valve body liner is dish spring, and dish spring internal-and external diameter arranges spiral wound gasket.Valve body liner makes there is no cavity in valve body, has avoided the accumulation of silica flour in valve body, and the outer internal diameter of dish spring arranges spiral wound gasket and can avoid silica flour to pile up at dish spring cavity, makes dish spring keep elastic force.
The utility model compared with prior art, there is following advantage and beneficial effect:
The utility model employing is of a size of 1.6-2.4 times of spheroid runner bore, can make spheroid only need 45-50 angle just can reach from standard-sized sheet to medium throttling, saves 1/3 switching time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of durable ball valve, comprise valve rod, valve body 1, valve rod is arranged on valve body 1 top, is provided with valve seat 2 and spheroid 3 in above-mentioned valve body 1, is provided with spheroid 3 in valve seat 2, in valve seat 2, be provided with valve seat runner 4, valve seat runner 4 matches with the fluid course 5 that valve seat 2 two ends are connected, and is provided with the spheroid runner 6 matching with valve seat runner 4 in spheroid 3, the diameter of spheroid 3 be spheroid runner 6 cross-sectional diameter 1.6-2.4 doubly.
General sphere diameter be spheroid runner outer diameter 1.3-1.5 doubly.
The spheroid of the present embodiment dams and only needs 45-50 degree to medium at spheroid standard-sized sheet, and the low strength of low moment of torsion is easily throttling just, reverses ball valve simple and fast more, because rotation angle is little, more can reduce the rotation of spheroid, reduces the loss of valve rod.And standard universal ball valve standard-sized sheet dams to medium and needs 70-75 degree, therefore large scale ball valve dam from spheroid standard-sized sheet to medium than standard universal ball valve fast 1/3 time, in the time transporting fluid, also just reduce fluid and washing away of internals reached to 1/3 chance.
In switching process, fluid forms the fluid of " S " type in spheroid runner and import and export thereof, wash away because fluid resistance causes at spheroid opening, under same little aperture, " S " type fluid of major diameter spheroid is more smooth, and " S " type fluid of standard ball is more rapid, therefore the fluid resistance of major diameter spheroid is more much smaller than universal standard spheroid, can greatly alleviate fluid washing away spheroid opening.
Embodiment 2
As shown in Figure 1, above-mentioned valve body 1 comprises left valve barrel 101 and right valve barrel 102, is forging.
Above-mentioned valve seat 2 comprises valve seat A201, valve seat middle part 203 and valve seat B202, and valve seat A201, valve seat middle part 203 and valve seat B202 are linked in sequence into a spherical hollow space solid forging that spheroid is installed.
Valve body 1 and valve seat 2 can guarantee the comprehensive sealing performance of whole valve body therefore to adopt forging can bring good sealing for forging.
Embodiment 3
