The utility model is characterized in that a hard cobalt-chromium-tungsten alloy layer (4-1) is overlaid on the sealing surface of the valve seat; a wolfram carbide layer (3-1) is coated on the sealing surface of a flashboard (3); flange sealing rings (6)are installed between the valve body (1) and the upper valve cover (11) and between the valve body (1)and the lower valve cover (32), and the valve body (1) is connected with the upper valve cover (11) and the lower valve cover (32) through a stud (28) and bolts (29). The utility model has the advantages that the valve is wear-resistant and sulfur-resistant, the sealing performance is good and the service life is long.
Description
Technical field
The utility model belongs to oil production equipment, particularly a kind of wear-resisting anti-sulphur double seal plate valve.
Background technique
China develops throttle well killing manifold and production tree since the beginning of the eighties, its technology is mainly continued to use the head valve loading amount of external import, the kind of early stage choke manifold product is more, and the choke manifold of present domestic use and production tree are common cast steel gate valve basically; These gate valve wearing and tearing and internal and outernal leakage are serious, and the defective of casting valve body itself makes this device reliability low, and working life is short.Drilling well mouth number was near 30,000 mouthfuls in present domestic year, every mouthful of oil well needs a cover kill-job loading amount and a production tree at least, every cover kill-job loading amount need be equipped with 8 plate valves, such valve surplus every cover production tree needs 10, consumption is big well imagines, improves to have very big social benefit and economic benefit its working life.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, a kind of wear-resisting anti-sulphur double seal plate valve that is mainly used in long service life, good seal on oil well choke manifold and the production tree is provided.
The technological scheme that the utility model technical solution problem is adopted is: a kind of wear-resisting anti-sulphur double seal plate valve of being made up of valve body, valve seat, valve rod, bonnet, bottom flange, filler gland, support, handwheel and dust-proof cover, be characterized in built-up welding cobalt chromium tungsten hard alloy layer on the sealing surface of valve seat, sprayed wc layer on the sealing surface of flashboard, between valve body and bonnet and bottom flange, the flange seal ring is housed, is connected with nut with the body lid with body lid stud bolt.
The beneficial effects of the utility model are: wear-resisting, the anti-sulphur of this plate valve, be suitable for the medium of well head aqueous slurry, and can under abominable working condition, work; Sealing pair adopts parallel flashboard structure, and on its sealing surface the sprayed wc layer, like this in the valve closing process, can utilize medium act on power on the flashboard with the sealing pair of flashboard and valve seat in conjunction with closely, reach the soft or hard double seal, improved the sealability of valve; Built-up welding cobalt chromium tungsten hard alloy layer on the sealing surface of valve seat, the sealing surface sprayed wc layer on the flashboard has wear-resistantly, and has the ability of self-cleaning, long service life.
