Description
Technical field
The utility model relates to valve field, specifically a kind of bar core integrated strip filter screen welding ball valve.
Background technique
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.Be provided with spheroid in ball valve, realize opening or closing the function of medium channel mainly through spinning ball, then cut-outs can be played, distribute and the effect in change media flow direction.
In the prior art, the valve rod of ball valve is separated with ball core, and the notch inserting ball valve core with valve rod realizes synchronous rotary control, but the notch language stem wear of ball valve core is serious simultaneously, and easily loosen, lose synchronization control effect, ball valve is short for working life.And the medium containing impurity enters ball valve sealing face, can accelerate the rate of wear of spool, the working life of ball valve is short.
Model utility content the utility model aims to provide a kind of bar core integrated strip filter screen welding ball valve, is intended to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of bar core integrated strip filter screen welding ball valve, comprises left valve barrel, right valve barrel, it is characterized in that: left valve barrel and right valve barrel, by welding formation integrated type valve body, are provided with the fluid origin spool with valve-stem integrated in the middle of valve body; Described valve rod and valve body joint are provided with only oozes parts; Described left valve barrel and right valve barrel are also having annular groove in port position, and annular groove is communicated to valve outer surface, and be provided with the filter screen with medium fluid path adaptation in annular groove, filter screen is provided with metal fixed border, and metal fixed border is wrapped in fluorine rubber ring; The diameter of described fluorine rubber ring is greater than the diameter of medium fluid passage.
Further, described in do valve body and right valve barrel outer surface has the hole lattice with annular groove adaptation, and be provided with the protective cover with hole lattice adaptation.
Further, described metal fixed border is provided with drag hook.
Further, be provided with between described valve rod and valve body and seal O shape and enclose.
Further, described valve rod is also connected with handwheel with bolt.
One, the beneficial effects of the utility model are: in medium fluid passage, be provided with filter screen, and a large amount of residue can stop by filter screen in bad working environments, avoid entering ball core rapid wear.
Two, simultaneously at metal fixed border outer wrapping fluorine rubber, can seal action be played, avoid medium to reveal from metal fixed border and valve body gap.
Three, annular groove is communicated to valve outer surface, over time, only need open protective cover; drag hook on pull-up metal fixed border, just can, by filter screen pull-out cleaning, insert in annular groove by filter screen after having cleaned again; structure is simple, and the time of cost is few, economical and practical.
Four, valve rod and ball core unitary design, stopped the wearing and tearing of valve rod plug and ball valve core notch, improves the working life of ball valve.
Five, valve body is welded into by left and right valve body, and structure is more stable.
Accompanying drawing explanation
Fig. 1 is the bar core integrated strip filter screen welding ball valve structural representation that the utility model provides.
Fig. 2 is the filter screen structure schematic diagram that the utility model provides.
Mark in figure: 1 be annular groove, 2 be protective cover, 3 be right valve barrel, 4 be filter screen, 5 be valve seat, 6 for spool.7 being left valve barrel, 8 being valve rod, 9 be sealing O shape circle, 10 being drag hook for oozing parts, 12 till handwheel, 11,13 be fluorine rubber ring, 14 be metal fixed border.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of bar core integrated strip filter screen welding ball valve, comprise left valve barrel 7, right valve barrel 3, it is characterized in that: left valve barrel 7 and right valve barrel 3, by welding formation integrated type valve body, are provided with the spool 6 become with valve rod 8 integrally casting in the middle of valve body; Described valve rod 8 is provided with valve body joint and only oozes parts 11; Described left valve barrel 7 is also having annular groove 1 with right valve barrel 3 in port position, annular groove 1 is communicated to valve outer surface, be provided with the filter screen 4 with medium fluid path adaptation in annular groove 1, filter screen 4 is provided with metal fixed border 14, and metal fixed border 14 is wrapped in fluorine rubber ring 13; The diameter of described fluorine rubber ring 13 is greater than the diameter of medium fluid passage.Described left valve barrel 7 has the hole lattice with annular groove adaptation with the outer surface of right valve barrel 3, and is provided with the protective cover 2 with hole lattice adaptation.Described metal fixed border 14 is provided with drag hook 12.Be provided with between described valve rod and valve body and seal O shape and enclose 9.Described valve rod is also connected with handwheel 10 with bolt.
Valve body is welded into by left and right valve body, and structure is more stable.Valve rod 8 and ball core 6 unitary design, stopped the wearing and tearing of valve rod plug and ball valve core notch, improves the working life of ball valve.To be provided with the close port position of right valve barrel 3 at left valve barrel 7 simultaneously and conveniently to get slotting filter screen 4, a large amount of residues can be adsorbed, also embraced fluorine rubber ring outward at metal fixed border, and played seal action, prevent medium from the gap leakage of annular groove.Often through after a while, open for dust-proof protective cover 2, catch on drag hook with hook and can take out filter screen 4 in annular groove and clean, simple and fast, efficiency is high.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
