As shown in Figure 1 to Figure 3, the present embodiment provides a kind of ceramic V-type regulation ball valve, including sphere 3, valve body 4, valve rod 2, Handwheel 1 and compensation mechanism 7, sphere 3 are arranged inside valve body 4, and sealing element 6, sphere 3 are provided between sphere 3 and valve body 4 On offer V-type through-hole 5, sphere 3 is spheres of ceramic 3, improves the wearability of sphere 3,2 one end of valve rod is through valve body 4 and sphere 3 It is connected, handwheel 1 is mounted on the other end of valve rod 2, and compensation mechanism 7 is arranged in the bottom of valve body 4 and is located under sphere 3 End, compensation mechanism 7 include mounting seat 12, compensating plate 11, lifting column 19, sliding panel 14 and mobile column 17, are set on valve body 4 It is equipped with opening 8, opening 8 is located at the lower end of sphere 3, and mounting seat 12 is mounted on 8 corresponding valve bodies 4 of opening by screw, peace It is provided with installation cavity 13 in dress pedestal 12, sliding slot 15 is provided on the inner wall of installation cavity 13, sliding panel 14 is slidably arranged in sliding slot In 15, mobile column 17 is fixed at the inner surface of sliding panel 14, is provided between the outer surface and installation cavity 13 of sliding panel 14 Propelling spring 18, propelling spring 18 are fixed on the side wall of installation cavity 13, compensating plate 11 setting opening 8 in, sphere 3 with The upper surface of compensating plate 11 is in contact, and 19 one end of lifting column is fixed at the lower surface of compensating plate 11, and the other end is through installation Pedestal 12 is in contact with mobile column 17.In order to guarantee the stability and stationarity of work, mobile column 17 and sliding panel 14 are respectively arranged There are two, two mobile columns 17 and two sliding panels 14 are symmetricly set on the two sides of lifting column 19.

Pressure control mechanism 10 is provided at the water inlet 9 of valve body 4, pressure control mechanism 10 includes screw rod 25, adjustable plate 24, seal receptacle 23 and knob 21, seal receptacle 23 are fixed on valve body 4, and adjustable plate 24 is arranged in the water inlet 9 of valve body 4, Screw rod 25 is located in seal receptacle 23, and 25 one end of screw rod is fixedly connected through valve body 4 with adjustable plate 24, and knob 21 is fixed at spiral shell The other end of bar 25 is provided with airtight and watertight padding 22 in 23 bracket of screw rod 25 and seal receptacle.In order to preferably control the water inlet of valve body 4 The pressure of mouth 9, the front end of adjustable plate 24 are in arc-shaped.

17 one end of mobile column and 19 one end of lifting column are provided with cup head 16, the cup head 16 and liter of 17 one end of mobile column The tangent setting of cup head 16 of 19 one end of column is dropped.When there is abrasion condition, sliding panel 14 drives mobile column 17 mobile, mobile column Cup head 16 on 17 pushes the cup head 16 on lifting column 19, so that lifting column 19 drives compensating plate 11 to move up realization certainly Dynamic compensation.

It is provided with reset spring 20 between the lower surface and mounting seat 12 of compensating plate 11, reset spring 20 is fixed at The upper surface of mounting seat 12.

The course of work of this example: when work, rotation hand wheel 1 makes the V-type through-hole 5 on sphere 3 be connected with water inlet 9 Logical, by continuous rotation hand wheel 1, V-type through-hole 5 and the contact area of water inlet 9 on sphere 3 are continuously increased, and are realized to Jie The control of mass flow amount, and V-type through-hole 5 also acts as shear action.When the pressure of water inlet 9 is excessive, by rotating knob 21 So that screw rod 25 declines, adjustable plate 24 is driven to decline, adjustable plate 24 is located at the intermediate position of water inlet 9 at this time, being capable of block media To directly washing away for sphere 3, erosion of the medium to sphere 3 is reduced；When 9 pressure of water inlet is too small, it is by rotating knob 21 Screw rod 25 rise, drive adjustable plate 24 to rise, 24 block media of adjustable plate avoided to flow to sphere 3, improve velocity of medium.

When for a long time in use, the sealing element 6 between sphere 3 and valve body 4 can generate abrasion, between sphere 3 and sealing element 6 Will form gap, when there is abrasion condition, sliding panel 14 under the action of propelling spring 18 along the chute 15 move inward and Drive mobile column 17 mobile, the cup head 16 in mobile column 17 pushes the cup head 16 on lifting column 19, so that 19 band of lifting column Dynamic compensating plate 11, which moves up, realizes fitting closely for sphere 3 and sealing element 6, the gap between elimination sphere 3 and sealing element 6, Enhance leakproofness, and mutually rotated between the lower part of sphere 3 and compensating plate 11, will cause the abrasion of compensating plate 11, mends Compensating plate can also be guaranteed under the action of reset spring 20 and under the action of sliding panel 14, propelling spring 18 by repaying after plate 11 is worn It is closely connected between 11 and sphere 3.

By the mounting seat 12 of setting, compensating plate 11, lifting column 19, sliding panel 14 and mobile column 17, when sealing element 6 is ground After damage, compensating plate 11 will push sphere 3 and move up, and guarantee good leakproofness between sphere 3 and sealing element 6, and under sphere 3 It mutually being rotated between portion and compensating plate 11, sphere 3 is the spheres of ceramic 3 of wear-resistant material, it is not easy to wear, after long-time use Replace compensating plate 11 both can, prolong the service life, reduce maintenance cost；

By the screw rod 25 of setting, adjustable plate 24, seal receptacle 23 and knob 21, the water inlet 9 of adjustable valve body 4 into Water pressure prevents from causing the sealing surface of sphere 3 by medium erosion because intake pressure is excessive, thus extend the service life of sphere 3, Reduce maintenance rate.

One or more embodiments of the utility model are described in detail above, but the content is only that this is practical Novel preferred embodiment, should not be considered as limiting the scope of the present invention.It is all according to present utility model application model All the changes and improvements made by enclosing etc., should still belong within the patent covering scope of the utility model.
