Abstract
The utility model relates to a ceramic ball valve for a strong corrosive medium and belongs to a valve. A main valve body is connected with an auxiliary valve body to form a valve cavity and a valve seat with an integral ceramic structure is arranged in the valve cavity. A valve ball with an integral ceramic structure is clamped in the valve seat. The upper end of the valve ball is provided with a valve rod hole. A metal sleeve is arranged in the valve rod hole. A valve rod is made of a corrosion-resisting alloy material and is inserted in the valve rod hole. A ceramic tube is embedded in a lining of the auxiliary valve body. A corrosion-resisting gasket is arranged between the main valve body and the auxiliary valve body. The valve ball and the valve seat of the ceramic ball valve are of a ceramic structure, so that the ceramic ball valve has wear resistance, acid and alkali resistance and corrosion resistance; due to the metal sleeve structure, pressure is transferred, the ceramic ball valve is suitable for harsh working conditions such as the strong corrosive medium and the like, the safety operation of the ball valve is ensured, the service life of the ball valve is prolonged, the anti-leakage sealing under the high pressure is ensured, and the sealing effect is good.
Description
Technical field
The utility model belongs to a kind of ball valve, and particularly a kind of strong corrosive media is used ceramic ball valve.
Background technique
Existing ball valve mostly adopts metal hard-sealing, and it has the low advantage of cost, but in bad working environments such as particle, dust, deep-etching, uses, and exists the quality instability, and poor sealing performance is prone to reveal, and working life is short, the defective of Maintenance and Repair trouble.
The model utility content
The purpose of the utility model is to overcome above-mentioned defective, provides a kind of strong corrosive media to use ceramic ball valve, and it is applicable to strong corrosive media, has alleviated the labor intensity of safeguarding, has guaranteed the safe operation of ball valve.
The purpose of the utility model realizes through following technological scheme: a kind of strong corrosive media is used ceramic ball valve, it is characterized in that: it comprises main valve body, auxiliary valve body, valve rod, valve seat and valve ball, and main valve body and auxiliary valve body connect and compose a valve pocket; Put left valve seat and right valve seat in the valve pocket, left valve seat and right valve seat clamp valve ball, and valve ball is the bulk ceramics structure; The valve ball upper end is provided with valve rod hole; Metallic sheath is installed in the valve rod hole, and valve rod is an anti-corrosive alloy material, is inserted in the valve rod hole; Valve seat is the bulk ceramics structure; The ceramic embedded pipe of auxiliary valve body liner, the spherical ceramic of valve ball surface and left and right valve seat contact the corrosion-resistant pad of installation between main valve body and the auxiliary valve body closely with spherical sealing surface on the stoneware pipe opposing end faces.
The advantage and the beneficial effect of the utility model are:
1, valve ball, valve seat adopt ceramic structure, have the wear-resistant of pottery, acid resistant alkali, and decay resistance is applicable to bad working environments such as strong corrosive media, has guaranteed the safe operation of ball valve, prolongs the working life of ball valve.
2, corrosion-resistant pad is installed between main valve body and the auxiliary valve body, wear-resistant, acid resistant alkali, corrosion-resistant, guaranteed leak-tight seal under the high pressure, good sealing effect.
3, valve ball is provided with metallic sheath, makes propagation of pressure, has guaranteed the safety in utilization of condition of high voltage lower valve.
