Abstract
The utility model discloses a ball valve draws together spheroid form case, valve rod and valve body, the inside disk seat that is fixed with of valve body, spheroid form case is installed in the disk seat, spheroid form case includes the spheroid that is become by three block segmentation body groups and sets up the two layer filtering net between the three block segmentation body, the parting plane perpendicular to inside passage axis of cutting apart the body, valve rod and the fixed connection that personally experiences sth. Part of the body of cutting apart who is located the middle part, be equipped with the sealing washer between disk seat and the spheroid. The utility model discloses a multi -functional passageway ball valve can effectively get rid of impurity, and has reduced the effect of the velocity of flow and pressure, reduces long -term wearing and tearing and impact to ball valve, has prolonged ball valve's life.
Description
Technical field
The utility model designs valve field, more particularly, to a kind of multifunctional channel ball valve.
Background technology
It is referred to as ball valve using spheroid as the valve of closure member, there is the action ratating 90 degrees, faucet body is spheroid, has circle
Through hole or passage pass through its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and changing medium in pipeline, and it is only
Need the operation with ratating 90 degrees and the rotating torque of very little just can close tightly, but ball valve design is become to make by recent development
It has throttling and controls flow to be used, and is widely used to oil, chemical industry, generating, papermaking, atomic energy, aviation, rocket etc. each
In department, and people's daily life.
Current ball valve is primarily present two problems: one be pipe-line very long although saying it is to be cleaned, but
Still cannot ensure that whole impurity are all cleaned, these impurity can enter in ball valve with current, can scratch or even damage
Bad shot body sealing surface and sealing surface of seat.Two is during ball valve switch, sometimes by ball valve as half-open half shape closing
Under state, then current will outflow rapidly, now pressure increase, ball valve serious wear can be led to, can cause in the course of time in
Leakage problem, and also meeting waste water resource, service life is reduced significantly.
Content of the invention
The purpose of this utility model is to provide a kind of multifunctional channel ball valve, can effective impurity screening, and alleviate ball
Valve weares and teares, and extends service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ball valve, including sphere-shape valve element, valve rod and valve body, described valve inner is fixed with valve seat, described spheroid
Shape valve element is installed in valve seat, and described sphere valve element includes the spheroid being made up of three pieces of dividing bodies and is arranged at three pieces of segmentations
Two-layer screen pack between body, the divisional plane of described dividing body perpendicular to inner passage axis, described valve rod with positioned at middle part
Dividing body is fixedly connected, and is provided with sealing ring between described valve seat and spheroid.
It is the first screen pack near the screen pack of inlet end, be the second screen pack near the screen pack of water outlet end, institute
The mesh aperture stating the first screen pack is more than the mesh aperture of the second screen pack.
Described screen pack is stainless sheet steel, its surface stamping dense aperture.
Described valve seat is fixedly connected with the valve body by dismountable banking pin.
Described dividing body is made up of pottery.
The beneficial effects of the utility model are: are provided with two-layer screen pack in valve element, realize double-filtration, effectively remove
Screen pack in impurity, and valve element serves the effect reducing flow velocity and pressure, reduces the long term wear to ball valve and impact, prolongs
Grow the service life of ball valve.
Brief description
Ball-valve structure schematic diagram in Fig. 1 the utility model embodiment.
Specific embodiment
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
A kind of ball valve, is made up of valve element 2, screen pack 4, valve rod 3, valve body 1 and valve seat five part.By traditional segmentation of spheres
For three pieces, add two-layer screen pack, the valve element 2 in group cost implementation between three pieces of dividing bodies.Along water inlet direction, described mistake
Filter screen includes the first screen pack 4 and the second screen pack 4, and the aperture of the mesh of the first screen pack 4 is more than the second screen pack 4
The aperture of mesh, serves the effect of double-filtration, effectively filters the problem of impurities in water.The material of described screen pack 4 is not
Rust steel sheet, its surface rush between aperture, and valve seat add sealing ring 5 it is ensured that sealing reliability.In addition in order to ensure
The impurity under filter screen filtration can be removed after long-time use, make spheroid rotate 180 degree current the impurity punching filtering down
Go out, we the fixing device on valve seat be changed to dismountable banking pin it is ensured that ball valve in working order in 90 degree of rotation,
Cleaning process can be rotated with 180 degree.This outer sphere can make the surface quality it is ensured that spheroid of pottery.
