Abstract
The utility model discloses a ball valve core which comprises a spherical valve core body. A fluid passage allowing media to flow past is arranged in the valve core body which is provided with a valve rod mounting slot, the cross section of the fluid passage is 'V'-shaped, the fluid passage comprises an inflow passage and an outflow passage which are mutually communicated and respectively extend to the surface of the valve core body to respectively form an inflow port and an outflow port on the surface of the valve core body, and inner side walls of the inflow passage and the outflow passage are cylindrical camber surfaces. The inflow passage and the outflow passage are arranged to be 'V'-shaped, so that the ball valve core can be used when an input pipeline and an output pipeline are arranged with an angle, processing is further facilitated, and the valve core body of a ball valve with the structure can be conveniently used when the input pipeline and the output pipeline are angled.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of ball valve core.
Background technique
Ball valve is a kind of open-shut device, comprise the valve body that is provided with valve pocket, be provided with valve rod, spherical spool body in the valve pocket, the spool body is provided with the circulation passage of crossing for MEDIA FLOW, comprises flow pass and flows to passage, flow to passage, flow pass all with the valve pocket conducting, be connected with valve rod on the spherical spool body, valve rod is used for the rotation of drive ball core, thus corresponding channel connection on control circulation passage and the valve body, namely control ball valve unlatching, close.Wherein, ball core and valve rod are linked through locating stud.
But, the spool of the ball valve of this structure, because circulation passage is straight passage, therefore, and can only be at corresponding intake line, could use when output pipe is located along the same line, just can not use when vertically arranging for intake line, output pipe.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides a kind of ball valve core easy to use, can not use point-blank the time at intake line, output pipe.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of ball valve core, comprise spherical spool body, be provided with the fluid passage of crossing for MEDIA FLOW in the spool body, the spool body is provided with valve rod slot is installed, the cross section of described fluid passage is V-shaped, what described fluid passage comprised mutual conduction flows to passage and flow pass, describedly flow to passage and circulation passage extends to respectively the spool body surface, form at the spool body surface respectively and flow to mouth and outflow opening, the described madial wall that flows to passage and flow pass is the cylinder cambered surface.
As preferably, described valve rod is installed slot and is comprised the first installation slot that is interconnected and the second installation slot that is arranged on the spool body end face, the described first cross section that slot is installed is rectangle, the described second transversal face that slot is installed is circular, described first installs slot near spool body end face, and is positioned at the second installation slot top.After adopting above-mentioned preferred version, dual slot and shape are different, can make valve rod inject valve rod the rotation of slot band movable valve plug body is installed, can guarantee that the spool body is can not produce loosening phenomenon in rotation, thereby make the closure or openness of valve more accurate.
As preferably, describedly flow to channel centerline and flow pass center line are all installed slot with valve rod reeve perpendicular direction setting.
After adopting above-mentioned preferred version, since the spool body flow to passage and flow pass generally all is horizontally disposed with, and valve pocket generally vertically arranges, and therefore, flows to channel centerline and flow pass center line are all installed slot with valve rod reeve perpendicular direction setting.Adaptability is stronger.
As preferably, " V " shape of described fluid passage is crossed and is formed by described passage and the flow pass of flowing to, and flows to passage and becomes the obtuse angle with flow pass.
After adopting above-mentioned preferred version, circulate more smooth and easy, if flow to passage and flow pass is acute angle, for the higher fluid of some viscosity, because the drastic shift of angle, cause possibly the obstruction of medium, the impact circulation.
Ball valve core of the present utility model flow to passage and the V-shaped setting of flow pass, can when being angle and arranging, intake line, output pipe use, and can be so that process convenient, the spool body of the ball valve of this structure can convenient use when intake line, output pipe angulation.

Embodiment
Such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, embodiment of the present utility model is a kind of ball valve core specifically, comprise spherical spool body 1, be provided with the fluid passage 2 of crossing for MEDIA FLOW in the spool body 1, spool body 1 is provided with valve rod slot 3 is installed, the cross section of fluid passage 2 is V-shaped, what fluid passage 2 comprised mutual conduction flows to passage 21 and flow pass 22, flow to the surface that passage 21 and circulation passage 22 extend to respectively spool body 1, and flowing to mouth 211 and outflow opening 221 in the formation of the surface of spool body respectively, the madial wall that flows to passage 21 and flow pass 22 is the cylinder cambered surface." V " shape of fluid passage 2 crosses and forms by flowing to passage 21 and flow pass 22, flows to 22 one-tenth obtuse angles of passage 21 and flow pass, is 120 °.
Valve rod installation slot 3 comprises the first installation slot 31 that is interconnected and the second installation slot 32 on the end face that is arranged on spool body 1, the first cross section that slot 31 is installed is rectangular, the second transversal face that slot 32 is installed is circular, first installs slot 31 near the end face of spool body 1, and is positioned at the second top that slot 32 is installed.
Flow to the center line of the center line of passage 21 and flow pass 22 is all installed slot 3 with valve rod reeve perpendicular direction setting.
