Abstract
The utility model relates to a butterfly valve of a circumferential outer groove valve sealing ring which has the roll forming inlay, comprising a valve body, wherein a butterfly plate is arranged inside the valve body; a sealing auxiliary is disposed between the valve body and the butterfly plate; the sealing auxiliary is composed of a butterfly plate sealing ring which is enchased on the outer circumference of the butterfly plate and a valve sealing ring which is enchased on the inner circumference of the valve body; the valve sealing ring is enchased on a valve sealing ring pedestal; the valve sealing ring pedestal is a boss ring on the inner wall of the valve body; the valve sealing ring is a metal valve sealing ring which is made of stainless steel or copper; the inner circumference of the valve sealing ring is provided with a sealing lip; the outer circumference of the valve sealing ring has a circumferential outer groove which is matched with the boss ring of the valve sealing ring pedestal; and a sealing ring is disposed between the outer circumference of the valve sealing ring and the valve sealing ring pedestal. The valve sealing ring of the utility model can use the armor plate strip or the copper plate strip as material and be enchased on the valve sealing ring pedestal in the method of roll forming inlay. The material used is less, and the processing charges are lower.
Description
Technical field
The utility model relates to the valve seal ring of a kind of butterfly valve, particularly a kind of butterfly valve.
Background technique
Butterfly valve has valve body, and butterfly plate is arranged in the valve body, between valve body and the butterfly plate sealing pair is arranged, and sealing pair is made up of the valve seal ring that is set in the butterfly plate seal ring on the butterfly plate excircle and be set on the valve body inner circumference.The valve seal ring of some butterfly valve is the metal valve body seal ring that becomes with stainless steel or copper, the metal valve body seal ring is on the valve seal ring seat that is embedded on the valve body inner circumference with locating, the valve seal ring seat is the boss ring at valve interior wall, the valve seal ring has seal lip, the excircle of valve seal ring is a toroidal surface with the face that the inner circumference of valve seal ring seat links to each other, for the valve seal ring is installed on the valve seal ring seat, in the prior art, the valve seal ring is installed on the valve seal ring seat with screw with locating, the section area of this valve seal ring is bigger, be to form during making with lathe car system, materials are more, processing charges is big, and the overall cost of product is higher.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and it is less to propose a kind of materials, and processing charges is less, and the overall cost of product is lower has the outside butterfly valve of groove valve seal ring of week that roll forming inlays.
The utility model is realized with the following method.
Have week that roll forming inlays outwards the butterfly valve of groove valve seal ring valve body is arranged, butterfly plate is arranged in the valve body, between valve body and the butterfly plate sealing pair is arranged, sealing pair is made up of the valve seal ring that is set in the butterfly plate seal ring on the butterfly plate excircle and be set on the valve body inner circumference, the valve seal ring is to be set on the valve seal ring seat, the valve seal ring seat is the boss ring at valve interior wall, the valve seal ring is to be embedded in stainless steel lath or the roll forming of copper coin bar to have an outside groove metal valve body seal ring of week on the valve seal ring seat boss ring, the inner circumference of valve seal ring has seal lip, the excircle of valve seal ring has the circumferential recess that matches with the boss ring of valve seal ring seat, between the excircle of valve seal ring and the valve seal ring seat sealing material is arranged.
The method that the available roll forming of valve seal ring of the present utility model is inlayed is embedded in the stainless steel lath or the roll forming of copper coin bar that are trapped among on the valve seal ring seat boss ring on the boss ring of valve seal ring seat.When inlaying, the inner peripheral surface of valve seal ring seat convex platform ring is made the similar shape that is bordering on the seal lip of the valve seal ring inner circumference that matches with the butterfly plate seal ring, on the stainless steel lath of the spreading width that length matches with the boss ring inner circumferential length of valve seal ring seat, width is a bit larger tham valve seal ring seat boss ring or boss ring inner circumference that the copper coin bar is trapped among the valve seal ring seat, the method for inlaying with roll forming is embedded in stainless steel lath or the roll forming of copper coin bar above the boss ring of valve seal ring seat.
Roll forming and the inner circumference that is embedded in the valve seal ring on the valve seal ring seat only need a spot of processing can become seal lip, and the excircle of valve seal ring has the circumferential recess that matches with the boss ring of valve seal ring seat.
Available stainless steel lath of valve seal ring of the present utility model or copper coin bar are that the method that material is inlayed with roll forming is installed on the valve seal ring seat, and the valve seal ring cuts less, and materials are less, and processing charges is less, and the overall cost of product is lower.
Below in conjunction with accompanying drawing, the utility model is further described.
