Abstract
The utility model relates to a valve, in particular to a lining ceramic concentric V-shaped ball adjusting valve, which is used for conveying paper pulp and sewage, and contains solid particles and fiber fluid. The lining ceramic concentric V-shaped ball adjusting valve comprises a valve body; a connection disc is connected to the upper portion of the valve body; a stuffing press cover is positioned on the lower portion of the connection disc; a valve rod is positioned inside a flow passage of the valve body; a valve seat is arranged inside the flow passage on one side of the valve body; a ceramic coating layer is arranged on the inner wall of the valve seat; a valve core is connected to the lower portion of the valve rod; a ceramic coating layer is arranged on the surface of the valve core; a valve shaft is connected to the lower portion of the valve core; and a bottom cover is connected onto the valve body below the valve shaft. In the process of conveying the solid particles and two-phase flow mixed media, scabbing is not easily generated in the valve body, thereby the service life of the valve is greatly prolonged.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of concentric V-type ball of lined ceramics modulating valve that is used to carry paper pulp, sewage, contains solid particle and fiber fluid.
Background technique
The concentric V-type ball of lined ceramics modulating valve is the widely used class valves of industry such as oil, chemical industry, power station, air-conditioning system, sewage treatment, papermaking, the medium that it passes through is paper pulp, sewage, contain the fluid of solid particle and fiber, be applicable to the adjusting of media such as gas, liquid, steam, its good stability allows pressure reduction big.Its sealing pair pile-up welding hard alloy, the hardness height, wear-resisting property is good, anti-washing away.But easily scab in valve body when conveying solid substance particle and two phase flow mixed medium, its working life and sealability can not be met consumers' demand.
The model utility content
The purpose of this utility model provides the concentric V-type ball of a kind of lined ceramics modulating valve, and it is difficult in valve body scabbing in conveying solid substance particle and two phase flow mixed medium process, has improved the working life of valve greatly.
For solving the problems of the technologies described above, the utility model comprises: valve body, valve body top connects land, and Gland is positioned at the bottom of land, and valve rod is positioned at the runner of valve body, establish valve seat in the runner of valve body one side, the inwall of valve seat is provided with ceramic coating, and the bottom of valve rod connects spool, and the surface of spool is provided with ceramic coating, the spool bottom connects valve shaft, connects bottom on the valve body of valve shaft below.
Spool comprises: the sphere core body, and sphere core body top and bottom are respectively equipped with through hole, establish keyway in the through hole of sphere core body upper end, and the sphere core body is provided with V-shaped groove, and the sphere core surface is provided with ceramic coating.
Body cavity is provided with ceramic coating.
The spool that be provided with ceramic coating and the valve seat of the utility model by cooperatively interacting is difficult for scabbing in the valve body in solid particle of carrying in pipeline and the two phase flow mixed medium process, improved the working life and the sealing of valve greatly.

Embodiment
First kind of mode of execution of the present utility model: the utility model comprises as shown in Figure 1: valve body 1, and valve body top connects land 6, and Gland 5 is positioned at the bottom of land, and Gland is used for compressing the stuffing box stuffing box packing.Valve rod 4 is positioned at the runner of valve body, connects valve seat 2 in the runner of valve body one side, and the inwall of valve seat is provided with ceramic coating, the bottom of valve rod connects spool 3, the surface of spool is provided with ceramic coating 9, and the spool bottom connects valve shaft 7, connects bottom 8 on the valve body of valve shaft below.Spool comprises: the sphere core body, and sphere core body top and bottom are respectively equipped with through hole, establish keyway in the through hole of sphere core body upper end, and keyway cooperates transmission with the key of valve rod lower end, and the through hole of sphere core body lower end inserts valve shaft.Under the drive of valve rod, sphere core rotates around valve shaft.The sphere core body is provided with V-shaped groove, and V-shaped groove and valve base chamber on the sphere core body have shear action, is applicable to fluid, slip class fluid, the high viscosity fluid of fibre-bearing matter, contains the control of fluids such as polymer, particulate matter, crystalline solid.The sphere core surface is provided with ceramic coating 9.
The ceramic coating of the ceramic coating of valve base inner wall and sphere core surface all adopts the Al of weight ratio 97%
2O
3, 3% TiO
2Mixture at detonation flame spraying more than 1800 ° on valve seat and sphere core body, to increase the wear resistance of valve pocket.
As improvement of the present utility model, on body cavity, also be coated with ceramic coating.
When the utility model in use, the handwheel or the driven by motor valve rod that connect by valve rod rotate, and spool is contacted with complete valve seat make valve closes; Or spool and valve seat break away from and make valve opening.
