Description
Technical field
The utility model relates to valve field, specifically a kind of soft sealing plug valve with filter screen.
Background technique
Stopcock is mainly used in cutting off, connecting and throttle medium, is widely used in oilfield exploitation, conveying and refining equipment, is also widely used in petrochemical industry, chemical industry, coal gas, rock gas, liquefied petroleum gas (LPG), HVAC industry and general industry simultaneously.
State commonly used by stopcock is open in usual, when needs carry out locking to valve time, pulls valve rod, drives the faucet body choosing that upper-end surface is large, lower end surface is little to fill 90 degree, positive closing circulation passage.But in Long-Time Service process, common faucet body is owing to being the sealing of employing face, its poor sealing performance.And in use in bad working environments, often because medium is dirty, easily produce fouling, faucet body serious wear, working life is short.
Model utility content the utility model aims to provide a kind of soft sealing plug valve with filter screen, is intended to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
With a soft sealing plug valve for filter screen, comprise valve body, faucet body, valve rod, it is characterized in that: described faucet body top is provided with the block stoping faucet body to float, and is provided with the valve seat fitted tightly with faucet body between faucet body and valve body; Described valve seat is teflon material, shape and faucet body adaptation; Import and export seat in described valve body and also have annular groove, 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 valve outer surface has the hole lattice with annular groove adaptation, and is provided with the protective cover with hole lattice adaptation.
Further, be also provided with elastic compensation element between described valve seat and valve body, comprise spring and spring seat, spring seat is stuck in valve body.
Further, described metal fixed border is provided with drag hook.
The beneficial effects of the utility model are:
One, adopt soft PTFE seal valve seat, sealability is better, solves the problem of general stopcock poor sealing performance.
Two, adopt valve seat to seal, change the sealing of the face of common stopcock into linear sealing, sealability is better.
Three, be also provided with sealing compensation mechanism between valve seat and valve body, wear and tear to some extent at soft valve seat, when occurring revealing, energy auto-compensation, makes its sealability again reach requirement.
Four, in medium fluid passage, be provided with filter screen, a large amount of residue can stop by filter screen in bad working environments, avoids entering faucet body rapid wear.
Five, 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.
Six, 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.
Accompanying drawing explanation
Fig. 1 is the one band filter screen soft sealing plug 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 valve body, 2 be protective cover, 3 be annular groove, 4 be spring, 5 be spring seat, 6 be filter screen, 7 be faucet body, 8 be valve seat, 9 be valve rod, 10 be drag hook, 11 be fluorine rubber ring, 12 be filter grid, 13 for block.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of soft sealing plug valve with filter screen, comprise valve body 1, faucet body 7, valve rod 9, it is characterized in that: described faucet body 7 top is provided with the block 13 stoping faucet body 7 to float, and is provided with the valve seat 8 fitted tightly with faucet body between faucet body 7 and valve body 1; Described valve seat 8 is teflon material, shape and faucet body 7 adaptation; Import and export seat in described valve body 1 and be provided with the filter screen 6 with medium fluid path adaptation, filter screen 6 is provided with metal fixed border, and metal fixed border is wrapped in fluorine rubber ring 11, and metal fixed border is also provided with drag hook 10.The diameter of described fluorine rubber ring 11 is greater than the diameter of medium fluid passage; Described valve body 1 also has the annular groove 3 with fluorine rubber ring 11 adaptation, annular groove 3 is communicated to valve body 1 outer surface.Described valve body 1 outer surface has the hole lattice with annular groove 3 adaptation, and is provided with the protective cover 2 with hole lattice adaptation.Also be provided with elastic compensation element between described valve seat 8 and valve body 1, comprise spring 4 and spring seat 5, spring seat 5 is stuck in valve body.
Operationally, because using the soft seal valve seat 8 of teflon material, change the sealing of the face of common stopcock into linear sealing, sealability is better, and the work condition environment that stopcock is suitable for is more wide in range.Arrange in the import and export of valve body 1 simultaneously and conveniently get slotting filter screen 6, 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 6 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.
