Abstract
The utility model provides a sealing butterfly valve driven by a connecting rod, which has good sealing effect. The sealing butterfly valve comprises a valve body, a valve seat, a valve plate, a driving arm and a control arm, wherein, the valve seat is arranged on the inner wall of the valve body. Both two surfaces of the valve plate are respectively movably connected with the driving arm and the control arm. When the driving arm rotates, the working end surface of the valve plate can be attached to the valve seat. The contact surface is finely processed, so the sealing effect is good. The sealing butterfly valve has the advantages that: 1. the valve plate and the valve seat are in surface contact, so the sealing effect is good; 2. the contact surface can not be abraded; 3. the sealing butterfly valve is appliable to large-caliber valves; 4. the sealing butterfly valve is suitable for high-temperature environments.
Description
Technical field
The utility model relates to a kind of butterfly valve, is specifically related to a kind of connecting rod transmission seal butterfly valve.
Background technique
For line contacts, surface of contact is easy to wear between the valve plate of existing seal butterfly valve and the valve seat, and surface of contact is elastic component, and non-refractory, and easy deformation are so cause sealing effect bad.For large bore valves, difficult making of existing reed valve and cost are higher.
Summary of the invention
The purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of connecting rod transmission seal butterfly valve of good sealing effect to be provided.
The technical solution of the utility model is: a kind of connecting rod transmission seal butterfly valve, comprise valve body, valve seat, valve plate, master arm and control arm, described valve seat is located on the inwall of valve body, two faces of valve plate flexibly connect with master arm and control arm respectively, when master arm rotates, the operative end surface and the valve seat surface of valve plate are fitted, and surface of contact is through gold machining, good sealing effect.
For face contacts, sealing effect is better between the utility model valve plate and the valve seat.And owing to adopt the quadratic crank mechanism transmission,, be perpendicular to that surface of contact carries out slowly so contact between valve plate and the valve seat or when breaking away from, and can not produce friction between valve plate and the valve seat, avoided the wearing and tearing of surface of contact.Surface of contact adopts metallic material or temperature-resistant material to make, and is adapted at using under the hot environment.
The beneficial effects of the utility model: 1, valve plate is that face contacts, good sealing effect with valve base chamber; 2, surface of contact can not wear and tear; 3, be applicable to large bore valves; 4, be applicable to hot environment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
