Abstract
The utility model relates to a valve, in particular a high-pressure valve used for oil well head gas injection and discharging. The high-pressure valve comprises a valve body, a valve core, a valve lid, a guide screw, a washer, a washer press hat, a prop stand, an axle bearing, a gland, a silk mother, a press hat and a hand wheel. The utility model has a cone shape valve core and the sealing between the valve body and the valve core is of cone structure,thus the sealing effect is good. At the same time the utility model has the advantages of a long service life, low operation cost, and a simple structure. is also convenient to use and repair the utility model.
Description
Technical field
The utility model relates to a kind of valve, and a kind of specifically oil field shaft mouth that is applied in is used for the high pressure valve of gas injection and exhaust.
Background technology
At present, the oilfield pipeline is that its valve body is connected by steel ring with the valve gap place with the structure that the employed valve in gas injection pipeline junction adopts, the sealing of valve body is to realize by combination valve plate, expander seal receptacle and the sealed at both ends groove of valve body, its shortcoming is this kind valve seal weak effect, often produce gas leak phenomenon, the cost height of equipment operation because this valve just needs repairing for 1-2 time in use, has brought very big trouble to the user simultaneously.
Summary of the invention
The purpose of this utility model is that a kind of good sealing effect, long service life, high pressure valve that running cost is low will be provided.
The purpose of this utility model is to realize like this, this high pressure valve comprises valve body, spool, valve gap, leading screw, packing ring, the packing ring pressure cap, support, bearing, gland, screw, pressure cap, handwheel, its spool is arranged on the inside of valve body, valve gap is connected the upper end of valve body by bolt, leading screw passes valve gap and is connected with spool, between valve gap and leading screw, be provided with packing ring, packing ring is fixed by the packing ring pressure cap, on valve gap, be provided with support, screw is set in the support and is connected with leading screw, the support upper end is connected with gland by bolt, and the upper end of screw is connected with handwheel, is provided with bearing between support and the screw below gland.
The both sides of described valve body have connecting hole, and the inside of valve body has bellmouth.
Described spool is a cone shape, and the sealing means of cone structure is adopted in the sealing between valve body and the spool.
The sealed end of described valve gap and valve body is a spherical structure.
The utility model is owing to become spool design the shape of cone, the sealing means of cone structure is adopted in sealing between valve body and the spool, makes its good sealing effect, long service life, running cost low, and it also has simple in structure simultaneously, easy to use, be convenient to advantages such as maintenance.
