Description
Technical field
The utility model relates to a kind of mechanical equipment technical field, particularly relates to a kind of high-pressure ball valve.
Background technique
High-pressure ball valve is come out the 1950's, along with the develop rapidly of science and technology, production technology and product structure update, in the 40 short years, developed rapidly and become a kind of main valve class.In the country that western countries' industry is flourishing, the use of high-pressure ball valve is constantly risen year by year, in China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.
High-pressure ball valve is mainly used in blocking or connect the medium in pipeline, also can be used for the regulating and control of fluid, wherein firmly seal between V-type ball valve its V-type ball core and metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the medium such as fibre-bearing, a small solid material.And multi-pass ball valve not only can the interflow of control media, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.This class valve generally should level be installed in the duct.High-pressure ball valve it there is the action of 90-degree rotation, faucet body is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline, and it is tight that it only needs to use the operation of 90-degree rotation and very little moment of rotation just can close.Ball valve optimum makees switch, cut-off valve uses, but ball valve design has become to make it to have throttling and control the use of flow, as V-type ball valve by recent development.The main feature of high-pressure ball valve is compact structure own, sealing is reliable, structure is simple, easy to maintenance, and sealing surface and sphere are everlasting closed state, not easily by medium erosion, be easy to Operation and maintenance, be applicable to the general work media such as water, solvent, acid and rock gas, but also be applicable to the severe medium of operating conditions, as oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade.Ball valve body can be overall, also can be knockdown.
Current existing high-pressure ball valve due to working environment pressure large, unusual inconvenience when valve body carries out switching manipulation.
Summary of the invention
The technical problems to be solved in the utility model is a kind of easy to use, and fluid resistance is little, applied widely, is highly suitable for the high-pressure ball valve used in hyperbaric environment.
For solving the problem, the utility model adopts following technological scheme:
A kind of high-pressure ball valve, comprise valve body, bearing gland, gear-box and handwheel, spheroid is provided with in described valve body, through hole is provided with in the middle part of described spheroid, through hole can regulate flow velocity when spheroid rotates, gear is provided with in described gear-box, gear facilitates rotating sphere, more convenient to operate, axle sleeve is provided with in the middle part of described gear, described axle sleeve is fixedly connected with gear, described spheroid is provided with valve rod, described spheroid, valve rod and axle sleeve are fixedly connected sequentially, described bearing gland is fixedly connected with gear-box, bearing gland can keep the tightness of valve body, bearing is provided with in described bearing gland, it is smooth and easy that bearing keeps valve rod to rotate, described bearing and valve rod are rotationally connected, described handwheel is provided with backing plate, backing plate can keep hand wheel rotating to stablize, described backing plate is connected with hand wheel rotating, described backing plate is fixedly connected with gear-box, described handwheel is connected with gear transmission.
As preferably, described valve body two ends are provided with end cap, conveniently install valve body.
As preferably, described end cap is provided with mounting hole, conveniently valve body is installed.
