Description
Technical field
The present invention relates to valve field, specifically a kind of metal hard-sealing stopcock 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.
Summary of the invention the present invention aims to provide a kind of metal hard-sealing stopcock with filter screen, is intended to solve the problem.
For achieving the above object, technological scheme of the present invention is as follows:
With a metal hard-sealing stopcock 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 divided into interior valve seat and outer seat, and interior valve seat is fixed by screws in outer seat, and interior valve seat and outer seat joint place are also provided with seal washer, are also provided with counterbalance spring between interior valve seat and valve body; 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, described metal fixed border is provided with drag hook.
Further, be provided with between described outer seat and valve body and seal O shape and enclose.
Further, described seal washer is Expanded graphite.
Beneficial effect of the present invention is:
One, to adopt and the metal seat valve of faucet body shape adaptation and faucet body form metal hard-sealing, enhance the sealability of common stopcock, make stopcock energy brother be applicable to more occasion.
Two, valve seat is divided into interior outer seat, strengthens interchangeability of parts, outer seat and faucet body metal hard-sealing, after outer seat generation wearing and tearing are scrapped, only need change outer seat, save financial cost.
Three, split type valve seat processing is more simple, is applicable to produce in enormous quantities.
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.
