Abstract
The utility model discloses a fine control equilibrium ball valve, including valve body (1), valve body (1) is provided with valve ball (2) including valve casing (6) in valve casing (6), and valve ball (2) top is provided with the rectangle and revolves post (7), and the rectangle revolves post (7) and passes valve casing (6) and be connected with control valve rod (8), and the side is provided with valve opening (3), its characterized in that: valve opening (3) are fan -shaped setting, and central angle (31) aperture scope is between 60~80, the utility model discloses when effectively having solved current equilibrium ball valve and using in required precision high field, the flow control precision is low, can't satisfy the problem of required precision.
Description
Technical field
This utility model relates to valve arrangement technical field, is specifically related to a kind of accurate control equilibrium ball valve.
Background technology
Ball valve (ball valve) was come out the 1950's, along with updating of developing rapidly of science and technology, production technology and product structure, in the 40 short years, has developed rapidly and has become a kind of main valve class.In the country that western industrial is flourishing, the use of ball valve the most constantly rises.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.It has the action of 90-degree rotation, and faucet body is spheroid, has manhole to pass through its axis.At present, the valve opening of existing equilibrium ball valve valve ball generally major part uses manhole, but this manhole flow control accuracy when the field that some accuracy requirement are higher uses is poor, it is impossible to meet actual demand.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind of accurate controls equilibrium ball valve, and this utility model efficiently solves existing equilibrium ball valve when the field that required precision is high uses, and flow control accuracy is low, it is impossible to the problem meeting required precision.
This utility model is achieved through the following technical solutions:
A kind of accurate control equilibrium ball valve, including valve body (1), valve body (1) includes valve housing (6), valve ball (2) it is provided with in valve housing (6), valve ball (2) top is provided with rectangle rotation post (7), and rectangle rotation post (7) connects through valve housing (6) control valve rod (8), and side is provided with valve opening (3), it is characterized in that: described valve opening (3) is arranged in sector, central angle (31) open range is between 60 °～80 °.
The further Technological improvement plan of this utility model is:
Being provided with digital calibration dish (4) on described valve housing (6), digital calibration dish (4) is positioned at valve ball (2) rectangle rotation post (7) and valve housing (6) opposite position.
The further Technological improvement plan of this utility model is:
It is provided with digital display pointer (5) on rectangle rotation post (7) of described valve ball (2).
This utility model compared with prior art, has a following obvious advantage:
One, this utility model is made traditional ball valve valve opening into sector by circle, and when valve ball rotates, flow increasing or decreasing according to a certain percentage, the on-off action and the balanced valve that reach ball valve control flow effect.
Two, this utility model on the basis of existing ball valve, can change the valve opening shape of valve ball, low cost, can be widely popularized use.
Three, this utility model is provided with digital calibration dish, and commissioning staff, when debugging valve, can realize accurately regulation according to scale.
Accompanying drawing explanation
Fig. 1 is this utility model main TV structure schematic diagram；
Fig. 2 is this utility model plan structure schematic diagram；
Fig. 3 is this utility model valve ball structure schematic diagram；
Fig. 4 is this utility model valve housing and digital calibration dish structural representation.
Detailed description of the invention
As shown in Figure 1, 2, this utility model includes valve body 1, valve body 1 includes valve housing 6, valve ball 2 it is provided with in valve housing 6, valve ball 2 top is provided with rectangle rotation post 7, and rectangle rotation post 7 has control valve rod 8 through valve housing 6 connection, and side is provided with valve opening 3, described valve opening 3 is arranged in sector, and central angle 31 open range is between 60 °～80 °；Being provided with digital calibration dish 4 on described valve housing 6, digital calibration dish 4 is positioned at valve ball 2 rectangle rotation post 7 and valve housing 6 opposite position；It is provided with digital display pointer 5 on the rectangle rotation post 7 of described valve ball 2.
In conjunction with Fig. 1,2,3,4 summary work process of the present utility model:
First valve body 1 being accessed fluid line, then regulate the aperture of valve ball 2 by controlling valve rod 8, commissioning staff regulates the size of aperture by the scale on digital calibration dish 4, thus judges the size of flow.
Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also includes the technical scheme being made up of above technical characteristic combination in any.It should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
