Abstract
The utility model relates to a displacement-reversing flow-regulating ball valve core, comprising a spherical valve core body made of ceramic materials or stainless steel materials. The top of the valve core body is a valve stem, and the central portion of the valve core body is a medium through hole. An inlet end of the medium through hole is composed of a semicircle and a long joint, and an outlet end is composed of a circle with the center being deviated to the left from the middle axis of the medium through hole at a certain angle q, which is greater than or equal to 10 DEG but smaller than or equal to 20 DEG. The displacement-reversing flow-regulating ball valve core of the utility model overcomes the defects that in the prior art, common ball valve cores are poor in wear-resistance performance and corrosion-resistant performance. By the design of the outlet end and the inlet end, when the valve core is rotated to be switched on or off, the medium flow can be controlled and adjusted with high precision. In addition, due to the increase in the diameter of the outlet end and the displacement reversion, the washing of the flow channel wall of a valve seat by medium can be reduced, thereby improving the wear-resistance performance and the corrosion-resistant performance of the valve core and a ball valve. Furthermore, the displacement-reversing flow-regulating ball valve core of the utility model has the advantages of simple structure, high regulating precision and long service lifetime.
Description
Technical field
The utility model relates to a kind of displacement switching-over Flow-rate adjustment ball valve core, is applicable to that every profession and trade pipelines such as Coal Chemical Industry, oil, rock gas, medicine, power station cut off the ball valve of flowing medium and adjusting flow.
Background technique
Be applicable to that at present the cut-out flowing medium of every profession and trade pipelines such as Coal Chemical Industry, oil, sewage treatment and the ball valve core of adjusting flow adopt " V " shape entrance point mostly, outlet end uses the center of circle to be in the circle of medium through hole axis usually.When spool is in the folding working state of regulating flow; Because " V " shape entrance point, round exit end and medium through hole are failed the break-in drainage; And round exit port footpath is less, when high temperature, when high-pressure medium gets into valve seat, causes medium directly to wash away the valve seat flow path wall easily; So that but flow path wall quilt within a short period of time makes that towards wearing whole billiard ball valve is shorter working life.
Summary of the invention
To the above-mentioned defective that exists in the existing technology, the utility model aimed to provide a kind ofly anti-ly wash away, wearability is stronger, has than the long life, can change MEDIA FLOW to the displacement break-in ball valve of regulating flow use spool.
To achieve these goals; The utility model adopts following technological scheme: the entrance point of the spool fixed end of the valve rod on spherical valve core, valve core top, valve core bottom, the medium through hole at valve core middle part, medium through hole is engaged by semicircle and rectangular and constitutes; The circle that outlet end departs from medium through hole axis several angle q left by the center of circle constitutes, 10 °≤q≤20 °.
Valve core is processed by stupalith or stainless steel material.
The utility model adopts and to depart from the circular spool outlet end in medium through hole axle center, its role is to enlarge flow outlet bore, and changes the medium circulating direction, thereby avoid medium directly to wash away the valve seat flow path wall, reduces wearing and tearing, prolongs spool and ball valve working life.
The utlity model has following beneficial effect: both passed on conventional ball valve spool entrance point " V " shape technical matters; Make spool when rotarily opening or close, can carry out high-precision regulating and controlling to rate-of flow; Improved spool outlet end technology again; Through expand export bore with change MEDIA FLOW to, reduce medium to the washing away of valve seat flow path wall, prolonged spool wear-resisting property and working life.This technology can reduce the ball valve maintenance frequency, practices thrift equipment maintenance cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model structural front view;
Fig. 2 is the plan view of the utility model structure;
Fig. 3 is the left view of the utility model structure.
Among the figure: 1 valve rod, 2 valve cores, 3 entrance points, 4 spool fixed ends, 5 outlet end, q depart from the angle in medium through hole axle center for the outlet end circle.
Embodiment
As shown in the figure, the utility model comprises valve core 2, is processed by pottery or stainless steel material; The top of valve core 2 is a valve rod 1, and the bottom is a spool fixed end 4, drives valve core 2 through valve rod 1 and rotarily opens or close; Valve core 2 middle parts are medium through hole, are made up of with outlet end 5 UNICOMs entrance point 3, and entrance point is engaged by semicircle and rectangular and constitutes; The circle that outlet end 5 departs from medium through hole axis several angle q left by the center of circle constitutes, and 10 °≤q≤20 °, the bore that keeps outlet end 5 when making valve core 2 rotarily open or close is all the time greater than entrance point 3 bores; Outlet end 5 through the displacement break-in change MEDIA FLOW to; Medium is introduced positive runner, avoid medium directly to wash away the valve seat flow path wall, thereby reduce erosive wear and prolong spool and ball valve working life.
Claims (3)
1. displacement switching-over Flow-rate adjustment ball valve core; Comprise spherical valve core; The top of valve core is a valve rod, and the bottom is the spool fixed end, and the valve core middle part is a medium through hole; It is characterized in that the medium through hole entrance point is made up of semicircle and rectangular joint, the circle that outlet end departs from the medium through hole axis by the center of circle constitutes.
