Abstract
The utility model relates to the field of valves, particularly to a novel subsea valve. According to the novel subsea valve, the lower end of an upper outer tube is connected with a screw sleeve, the lower end of the screw sleeve is connected with a lower outer tube through a flange, seal rings are arranged inside the flange, the lower outer pipe tube is connected with a valve body, the bottom of the valve body is provided with a valve seat, and the inner wall of the valve seat is an inclined surface; a screw is arranged outside the outer tube, the upper end of the screw is connected with a hand wheel, the middle of the screw is threadedly connected with the screw sleeve, and the lower end of the screw is connected with a connecting rod through a spherical pair; the lower end of the connecting rod is connected with a sealing valve plate which is in a conical column shape, and the inclination of the inclined surface of the sealing valve plate is the same to the that of the inclined surface of the inner wall of the valve seat. The novel subsea valve has a V-shaped sealing surface and accordingly is reliable in sealing performance; by means of a plurality of the seal rings, even under the condition that the valve plate is closed, the inside of the valve body can be isolated from the outside, so that the sealing performance of the valve can be guaranteed, contact between the screw and mud or dust can be avoided, the operating flexibility of the screw can be guaranteed and the service life of the seat valve can be prolonged.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of seabed valve.
Background technique
Sea cock and valve, is installed on tank base, is applicable between the pipeline and storehouse of the mud circulation tank take mud as medium, as the control valve that sucks and discharge, also act as the switch of balance control between storehouse; Because sea cock and valve working environment has corrosivity, the leading screw of sea cock and valve easily contacts and is corroded with mud, dust, causes valve to be difficult to open, and has shortened the working life of sea cock and valve.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, good sealing effect, the seabed valve of long service life.
The technical solution of the utility model is:
Seabed valve, comprise outer tube, outer tube is divided into upper exterior tube and lower outer pipe, upper exterior tube top arranges filling butter mouth, upper exterior tube lower end connects screw set, screw set lower end connects lower outer pipe by flange, seal ring is set between flange, lower outer pipe connects valve body, valve body bottom arranges valve seat, the inwall of valve seat is inclined-plane, leading screw is positioned at outer tube, leading screw upper end connects handwheel, leading screw middle part is threaded with screw set, leading screw lower end is connected with connecting rod by spherical pair, connecting rod lower end connects sealing valve plate, sealing valve plate is circular cone cylindricality, the sealing inclined-plane gradient of valve plate is identical with the inclined-plane gradient of valve base inner wall.
Some seal rings are set between described leading screw and upper exterior tube.
Between described connecting rod and valve body top, some seal rings are set.
Described upper exterior tube top arranges filling butter mouth.
Described valve seat adopts stainless steel to make, and sealing valve plate adopts the nitrile rubber of metal sulfuration to make.
Sealing surface of the present utility model is V-arrangement, sealability is reliable, multiple-sealed circle is set, leading screw is all sealed in screw set, guarantees that valve inner is isolated from the outside in the situation that valve plate is closed, guarantee the sealing of valve, prevent again contacting of leading screw and mud, dust, guaranteed the flexibility of leading screw operation, extended the working life of sea cock and valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of empty frame A in Fig. 1.
Fig. 3 is the enlarged view of empty frame B in Fig. 1.
Fig. 4 is the enlarged view of empty frame C in Fig. 1.
1 upper exterior tube 2 screw set 3 lower outer pipe 4 flange 5 valve body 6 handwheel 7 leading screw 8 seal ring 9 connecting rods 10 seal valve plate 11 valve seat 12 seal rings.
Embodiment
Seabed valve, comprises outer tube, and upper exterior tube 1 top arranges filling butter mouth, be convenient to leading screw 7 butter of annotating, guarantee that leading screw 7 is flexibly movable, upper exterior tube 1 lower end connects screw set 2, screw set 2 lower ends connect lower outer pipe 3 by flange 4, seal ring 12 is set between flange 4, and lower outer pipe 3 connects valve body 5, and valve body 5 bottoms arrange valve seat, valve seat adopts stainless steel to make, make valve seat after long-time mud dipping washes away, can not affect because of getting rusty sealing, the inwall of valve seat is inclined-plane.
Leading screw 7 upper ends connect handwheel 6, some seal rings 8 are set between leading screw 7 and upper exterior tube 1, leading screw 7 middle parts are threaded with screw set 2, leading screw 7 lower ends are connected with connecting rod 9 by spherical pair, between connecting rod 9 and valve body 5 tops, some seal rings are set, connecting rod 9 lower ends connect sealing valve plate 10, sealing valve plate 10 adopts the nitrile rubber of metal sulfuration to make, the nitrile rubber compact structure of sulfuration, rigidity is strong, wear-resisting, acid resistant alkali, long service life, sealing valve plate 10 is circular cone cylindricality, the sealing inclined-plane gradient of valve plate 10 is identical with the inclined-plane gradient of valve base inner wall, the sealing surface that makes to seal valve plate 10 is V-shaped, guarantee sealing effect.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characteristics is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
