Abstract
The utility model relates to a three-way reversing ball valve. The valve comprises a valve body, a ball body, a valve seat, a valve rod, a valve cover and a transmission mechanism. A valve body channel is a three-way channel consisting of an inlet channel and two outlet channels; the valve seat is mounted between the valve body inlet channel and a valve cavity; outlet valve seats are respectively mounted among two outlet channels of the valve body and the valve cavity; the valve is mainly characterized in that a ball body channel is an arc structure; and channel centre lines among the inlet channel of the valve body and two outlet channels are arc lines. The utility model has the advantages of less medium kinetic energy loss, less scour of the flow channel, long service life of the product and the like; and the utility model is suitable for the switching valve of the medium reversing pipeline.
Description
Technical field
The utility model relates to valve field, and particularly about a kind of tee ball valve, the utility model is applicable to the switching valve of medium commutation pipeline.
Background technique
Tee ball valve is used in the flow direction of switchable dielectric on the three-way pipeline, its structure is comprised of valve body, spheroid, valve seat, valve rod, valve gap, driving mechanism, valve channel forms the three-port structure passage by an inlet passage and two outlet passages, be provided with valve seat at inlet passage and two outlet passages and body cavity joint, by rotating sphere valve body inlet passage and outlet passage are switched connection, realize the switching of medium.But, the passage of existing tee ball valve is T-shaped or the L-type structure, be valve body inlet passage and one of them outlet passage at an angle of 90, medium is larger to the impact of spheroid vias inner walls and body cavity, the medium kinetic energy rejection is larger, medium produces larger washing away to spheroid vias inner walls and body cavity, reduces valve working life.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, provide clear and coherent smooth, the medium of a kind of MEDIA FLOW by the time valve body and spheroid washed away three-way reversing spherical valve little, long service life.
The technical solution of the utility model comprises valve body, spheroid, valve seat, valve rod, valve gap, driving mechanism, valve channel forms three circulation passage by an inlet passage and two outlet passages, the import valve seat is installed between valve body inlet passage and valve pocket, difference installation outlet valve seat between valve body two outlet passages and valve pocket, mainly be that the spheroid passage is arcuate structure, the channel centerline between valve body inlet passage and two outlet passages is curved line.
In above technological scheme, the angle between the sealing surface of the sealing surface of import valve seat and two outlet valve seats is respectively 45 °.
In above technological scheme, at valve body inlet passage and two outlet passage difference mounting flanges, angle between valve body inlet passage flange axis and one of them the valve outlet passage flange axis is 135 °, and the angle between two valve outlet passage flange axis is 45 °.
The beneficial effects of the utility model are to form the arc runner between valve body inlet passage and the outlet passage, reduce the medium kinetic energy rejection, have reduced medium to the washing away of runner, and prolong product working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Three-way reversing spherical valve as shown in Figure 1, comprise valve body 1, spheroid 2, valve seat, valve rod, valve gap, driving mechanism, valve body 1 passage forms three circulation passage by an inlet passage and two outlet passages, import valve seat 3 is installed between valve body 1 inlet passage and valve pocket, difference installation outlet valve seat 4 between valve body 1 liang of outlet passage and valve pocket, 5, spheroid 2 passages are arcuate structure, channel centerline between valve body 1 inlet passage and two outlet passages is curved line, make medium when outlet passage flows through, reduce impact force to runner inner wall from valve body 1 inlet passage, reduce medium kinetic energy rejection and washing away runner.
Angle between the sealing surface of import valve seat 3 and two outlet valve seats 4,5 the sealing surface is respectively 45 °.
At valve body 1 inlet passage and two outlet passage difference mounting flanges, angle between the axis of the axis of valve body inlet passage flange 6 and one of them valve outlet passage flange 7 is 135 °, and the angle between two valve outlet passage flange 7,8 axis is 45 °.Angle between the axis of valve body inlet passage flange 6 and two valve outlet passage flange 7,8 axis can be according to the requirement design of erecting bed pipeline.
