Description
Technical field
The utility model relates to a kind of ball valve, especially relates to a kind of ball valve with filter screen.
Background technique
Ball valve means that open-shut device spool (spheroid) is driven by valve rod, and around the valve that ball valve axis rotates.Be mainly used in blocking or connect the medium in pipeline, also can be used for the regulating and control of fluid, wherein firmly seal between V-type ball valve its V-type ball core and metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the medium of fibre-bearing, a small solid material etc.And multi-pass ball valve not only can the interflow of control media, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.This class ball valve generally should level be installed in the duct.Ball valve is classified: pneumatic ball valve, electric ball valve, manual ball valve.But, for pipeline gas conveying, due to inner-walls of duct corrosion, pipe wall material is caused to come off, make purity higher conveying gas originally with a large amount of impurity, the purity of conveying gas cannot be ensured like this, time serious, even can affect normal industrial application and family's use.
Therefore, develop one and be often used in gas transmission pipeline, the ball valve of repeatedly purification conveying gas purity can be played, reduce the ball valve of IE Industrial Engineering gas risk factor and the dangerous cost of home-use gas, seem very important.
Model utility content
In order to overcome the deficiency of ball valve in existing gas transmission pipeline, the purpose of this utility model is providing a kind of ball valve with filter screen, filters out the impurity be mingled with in gas conveying, improves the purity of conveying gas.
The technical solution adopted in the utility model is:
The utility model comprises spanner, shaft block ring, positioning block, valve rod, two seal rings, spheroid, right valve barrel and left valve barrel; Right valve barrel and left valve barrel are built with spheroid, one end of valve rod is inserted in the groove of spheroid, and install positioning block between valve rod and right valve barrel, the other end of valve rod is equipped with spanner, between spanner and right valve barrel end face, shaft block ring is housed, seal ring is equipped with respectively in spheroid and right valve barrel and left valve barrel junction; Spheroid outer cover has filter screen that is identical with sphere structure shape, that be tangential on spheroid, and right valve barrel Lower Half has circular port, circular port and spanner median perpendicular and by spheroid centre of sphere line, circular port runs through mutually with right valve barrel Lower Half.
Described filter screen is made up of two-part, and wherein, not tangent with spheroid through hole part is entity filter screen, and the part tangent with spheroid outlet through hole cross section is that perforate filter screen is formed.
The perforate direction of described circular port is along gravitational direction.
The material of described filter screen is polyster fibre.
The beneficial effect that the utility model has is:
By the understanding to ball valve application area, combination seal principle, and the filtration of net shapes, ensure the purity of carrying gas in pipeline gas conveying, reduce the dangerous incidence rate of industrial gas and home-use gas.The utility model makes full use of the polyster fibre of good springiness, wear-resistant, corrosion-resistant, sealing, good heat resistance, and make with ball for ball valve tangent, external structure is the same, the filter screen of inner hollow.When ball valve is opened, this strainer filtering lives the impurity in conveying gas, is blocked; When ball valve is closed, the impurity in conveying gas, under gravity, along ball for ball valve through hole, discharges from the circular port of ball valve right valve barrel lower body.
The utility model is mainly used in reducing the impurity in Cemented filling gas, and is discharged, and can use by multiple ball valve, adopt different filter screen density, reach the effect of multiple filtration impurity along gas transmission pipeline segmentation.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the utility model comprises spanner 1, shaft block ring 2, positioning block 3, valve rod 4, two seal rings 5,10, spheroid 6, right valve barrel 8 and left valve barrel 9; Right valve barrel 8 and left valve barrel 9 are built with spheroid 6, one end of valve rod 4 is inserted in the groove of spheroid 6, positioning block 3 is installed between valve rod 4 and right valve barrel 8, the other end of valve rod 4 is equipped with spanner 1, between spanner 1 and right valve barrel 8 end face, shaft block ring 2 is housed, spheroid 6 is equipped with seal ring 5, seal ring 10 respectively with right valve barrel 8 and left valve barrel 9 junction.Spheroid 6 outer cover has filter screen that is identical with spheroid 6 structure shape, that be tangential on spheroid 6, and right valve barrel 8 Lower Half has circular port 11, and circular port 11 is vertical with spanner 1 center line c and by spheroid centre of sphere line, circular port 11 runs through mutually with right valve barrel 8 Lower Half.
As shown in Figure 4, described filter screen is made up of two-part, and wherein, not tangent with spheroid 6 through hole part is entity filter screen 7a, and the part tangent with spheroid 6 outlet through hole cross section d is that perforate filter screen 7b is formed.Two-part with the through hole cross section d of ball for ball valve 6 for boundary, but be an overall structure, not separated.
The perforate direction of described circular port 11 is along gravitational direction.
The material of described filter screen 7 is the polyster fibre of good springiness, corrosion-resistant, wear-resistant, sealing, good heat resistance.Good springiness: its Young's modulus is 22 ~ 141cN/dtex is higher than polyamide fibre 2 ~ 3 times; Corrosion-resistant: can bleach tolerant, oxygenant, hydro carbons, ketone, petroleum products and inorganic acid, resistance to diluted alkaline, be afraid of mould, but thermokalite can make it decompose, and also has stronger anti acid alkali performance, anti-ultraviolet ability; Wear-resistant: to be only second to the polyamide fibre that wear resistance is best, than other natural fibre and synthetic fiber all good; Good heat resistance: the fusing point of terylene is higher, and specific heat is empty and heat conductivity is all less, thus the heat resistance of polyster fibre and adiabaticity want height, are best in synthetic fiber.
As shown in Figure 1 and Figure 2, when rotating spanner 1, the spheroid 6 of ball valve will be driven to open and close by valve rod 4, being enclosed within filter screen tangent with spheroid 6 on spheroid 6 can be synchronized with the movement together with spheroid 6, realizes filtration.When spheroid 6 is closed, the through hole not adding the spheroid 6 of perforate filter screen 7b will overlap with circular port 11.
working principle of the present utility model and working procedure as follows:
The utility model is intended to by sealing principle, and the filtration of netted filter screen, ensures the purity of carrying gas in pipeline gas conveying, improves the Security of industrial gas and home-use gas.When rotating the spanner 1 of ball valve, the valve rod 4 of ball valve will drive spheroid 6 and the cover filter screen motion thereon of ball valve, and the spheroid 6 of ball valve realizes the keying of ball valve.When ball valve standard-sized sheet, conveying gas is carried in the duct, due to wall erosion, causes pipeline wall surface material to come off, and filter screen is used for filtering the impurity in conveying gas; When ball valve is closed, the spheroid 6 of ball valve will overlap with the circular port of right valve barrel bottom, period, and the impurity be filled in conveying gas under gravity, will be discharged from circular port 11, reach impurity screening, improves the effect of gas purity.
