Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of deep-sea underwater valve.
Background technique
Ocean has abundant energy resources, and the development and utilization of marine energy is seized of very important status in energy development.Marine energy exploitation is had relatively high expectations to equipment, especially the design of valve under water, manufacture, installation etc. is had to strict requirement.
Underwater valve claims again sea cock and valve (Subsea valve), is the valvular general designation that is used on submarine pipeline.At present, under water the main pooled applications of valve on the subsea manifold and conveyance conduit of marine oil and gas engineering.Due to valve under water under water can't maintenance, repair, replacing, so valve is under water had to higher reliability and better serviceability requirement.Particularly be used in the valve under water of natural gas line, because natural gas line has the characteristics such as pipeline pressure is high, flow velocity is fast, in the course of the work, valve internal will bear the pressure of fed sheet of a media under water, the outside pressure that will bear seawater, dive under water darker, and external pressure is larger.Simultaneously, seawater also has etching characteristic, so all higher to the requirement of selection, structure and the processing technology of valve under water.
In prior art, need badly a kind of selection rationally, novel structure, good manufacturability, underwater valve that combination property is stable.
Summary of the invention
The objective of the invention is the deficiency that exists in order to overcome prior art, provide a kind of selection rationally, novel structure, good manufacturability, underwater valve that combination property is stable.
the present invention is achieved by the following technical solutions: a kind of underwater valve, comprise valve body, rotatable two the interior spheroids of two valve chambers that are arranged at the valve body inner flow passage, be arranged at the valve seat bracing ring between two spheroids and valve body, two valve rods that are connected with two spheroids, be arranged at the upper end portion of valve body and two support boxes between two valve rods, two that are connected in two support box upper ends drive connecting plate and pass through bolt, nut is connected in two connecting bodys of valve body rear and front end, between support box and valve rod, be provided with sliding bearing, the equal built-up welding of the inner chamber of the inner chamber of described valve body and two described connecting bodys has nickel base alloy layer.
The present invention adopts two sphere structures designs, and is independent sealed between two spheroids and valve seat, when a ball seal structure breaks down, also has another spheroid can realize sealing function, improved reliability.Valve body and connecting body need to adopt high strength alloy steel, under internal pressure and external pressure effect, still can guarantee good mechanical property, and amount of deformation is in the permission range of material and seal request.Corrosion resistant nickel-base alloy layer thickness, greater than 3mm, meets dielectric corrosion and life of product requirement.Valve seat and valve rod are all selected the high corrosion resistant aluminium alloy material, and spherome surface sprayed wc alloy improves surface hardness and anti-scuffing function.By screw bolt and nut, valve body and connecting body are coupled together, cavity of inner formation, meet pressure medium and carry requirement.
Described bolt is connected with cover type nut, the front end of cover type nut and the outer surface of described connecting body touch, between the front end of cover type nut and this connecting body, be provided with the nut seal circle, the exposed parts of described bolt, described nut are all between cover type nut and connecting body, this structure stops seawater to produce corrosion, the working life of having improved fastening piece to the screw thread position of bolt, nut.
Described valve body is provided with respectively upper mounted plate and bottom plate by bearing pin in upper end portion and the underpart of described spheroid, between spheroid and upper mounted plate, bottom plate, is provided with positioning bearing.Upper mounted plate and bottom plate have effectively improved the centering of spheroid, avoid spheroid to depart from center and produce leakage and increasing friction force, and the moment of torsion while driving is only born in the valve rod operation, does not bear moment of flexure, and operational torque is little, convenient operated valve under water.
Described valve seat bracing ring is provided with spring groove, in this spring groove, be provided with spring, one end of spring is supported the bottom at spring groove, the other end of spring is supported on described valve body, between valve seat bracing ring and valve body, also be provided with valve seat lip-type packing and valve seat O RunddichtringO, between valve seat bracing ring and corresponding spheroid, be provided with valve seat triangular sealing ring and valve seat secondary seal circle.Between valve seat bracing ring and spheroid, adopt double sealing structure, arbitrary seal ring lost efficacy, another seal ring can also effectively stop dielectric leakage, and the valve seat triangular sealing ring is the rubber parts with premium properties, very strong self-healing function is arranged, even the impurity damage Sealing is arranged in medium, can not lose efficacy easily yet, make the present invention have reliability preferably.
Arranged outside in described bolt between described valve body and described connecting body has the valve body waterproof ring, between described valve body and described connecting body, in the inboard of described bolt, is provided with valve body lip-shaped sealed ring and valve body 0 RunddichtringO.
Between described support box and described valve body, be provided with lip-type packing and support box waterproof ring, between described support box and described driving connecting plate, be provided with the O RunddichtringO, between described support box and described valve rod, be provided with gland, between gland and valve rod, be provided with valve rod O RunddichtringO, between gland and support box, be provided with gland O RunddichtringO, between gland, valve rod and support box three, be provided with the valve rod lip-shaped sealed ring.
On described driving connecting plate, be connected with driving head bolt and driving head nut, drive between connecting plate and driving head nut and be provided with the nut waterproof ring, described driving connecting plate upper end also is provided with driving head, drives between connecting plate and driving head and is provided with driving head waterproof ring and valve rod waterproof ring.
Between valve seat bracing ring and valve body, valve body and connecting body, valve body and support box, valve rod and gland, driving connecting plate and driving head, driving connecting plate and support box, gland and valve body, select lip-type packing and O type to seal.The characteristics such as wherein, lip-type packing has that installation precision is high, good stability, decompression antiknock split.The O RunddichtringO can effectively stop seawater to enter valve corrosion parts.Adopt two combination seals to make valve performance more reliable.Nut arranges waterproof ring, stops seawater to enter the corrosion screw thread.
The invention has the beneficial effects as follows: the present invention adopts the double spherical sealing configuration, and two independently sealing configurations are provided, and can realize the function of two deck valve doors, weight is 2/3rds of a deck valve door, lighter during installation, time saving and energy saving, reliability also is improved simultaneously.The nickel-base alloy of valve body, connecting body inner chamber built-up welding highly corrosion resistant, can realize the function same with full nickel-base alloy valve, saves product cost, meets energy-conservation requirement.Valve body, connecting body, support box, valve rod etc. form the cavity of a sealing by Sealing and fastening piece, can stop medium to external leakage, and the design of waterproof ring simultaneously can stop seawater to enter valve.The present invention have advantages of selection rationally, novel structure, good manufacturability, combination property be stable.
