Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, light-type eccentric ball valve of the present utility model comprises valve body 1, valve ball 2, seal valve seat 3, thrust valve seat 4 and valve rod 5.
Valve body 1 is provided with cavity 11 on along its length, because the upper end of cavity 11 needs enough wall thickness, and its lower end is to wall thickness no requirement (NR), thereby the utility model is designed to eccentric structure cavity 11 and valve body 1, be specially the below at the center that is centered close to valve body 1 of cavity 11, the volume of valve body 1 can be effectively dwindled in the design of this spline structure, can ensure that again the upper end of cavity 11 has enough wall thickness, thereby save material and cost simultaneously.In a preferred embodiment, in valve body 1, be also provided with cooling groove 12, the impact of temperature conduction on light-type eccentric ball valve sealing of the present utility model when it can effectively reduce welding.
Valve ball 2 is arranged in the cavity 11 of valve body 1, and the center of valve ball 2 is provided with through hole 21, and valve ball 2 can rotate and then opening and closing cavity 11 with respect to valve body 1, thereby allows liquid to pass through from through hole 21 and cavity 11.
Seal valve seat 3 and thrust valve seat 4 are also arranged in the cavity 11 of valve body 1, and seal valve seat 3 and thrust valve seat 4 are separately positioned on the both sides of valve ball 2 and between valve ball 2 and valve body 1.In a preferred embodiment, a side of thrust valve seat 4 is provided with dish spring 6, so just makes valve ball 2 and seal valve seat 3 and thrust valve seat 4 Elastic Contact.
Valve rod 5 is connected rotationally with valve ball 2, and the end of valve rod 5 is provided with key 51, and the upper end of valve ball 2 is provided with groove 22, realizes the rotation of valve rod 5 to valve ball 2 thereby key 51 matches with groove 22.In a preferred embodiment, between the groove 22 of valve ball 2 and the key 51 of valve rod 5, there is gap 14 (referring to Fig. 4-6), when ball valve is during in closed state, the liquid being turned off produces pressure to valve ball 2, owing to being provided with gap 14, make valve ball 2 can more be close to seal valve seat 3, increased the sealing effect of ball valve.
Between the both sides of valve rod 5 and valve body 1, be respectively arranged with anti-extrusion filler 7 and stuffing box packing 8, the top that is positioned at anti-extrusion filler 7 and stuffing box packing 8 on valve rod 5 is provided with Glan lid 9, Glan lid 9 pushes anti-extrusion filler 7 and stuffing box packing 8, makes it have good sealing.The upper end of valve rod 5 is also provided with handle 13.
