Abstract
A bay flat slide valve comprising a valve body, a flashboard and a seal pair characterized in that a valve port on the valve body is a semicircle one with a plane bottom. The bottom of a seal flashboard bottom matched with the valve body is plane too. The seal pair on flashboard is an allotypic seal ring composed of one section of a plane and one section of an arc surface. An end sealing and a bottom sealing are formed between the allotypic seal ring and the valve body. The utility model is characterized in that it applies bottom plane design for the valve port, thereby leaving no residual medium during unloading and meet the requirements for using. Meanwhile, through the sealing of the two sealing surfaces of the seal pair, the utility model can offer reliable sealing performance.
Description
Technical field
The utility model relates to a kind of valve, especially for the flat mouthful of gate valve of isolating cabin.
Background technique
Existing separation gate valve peculiar to vessel, the valve port on the valve body are circular, and the sealing pair on the flashboard is a ring, and gate valve is in closed condition, form the end sealing between the end face of circular seal pair and the valve body.The problem that this gate valve exists is: in the unloading cabin during flowing medium, can not tank evacuation in medium, cause the residual of cabin medium.
Summary of the invention
But the purpose of this utility model is to provide a kind of without hindrance separation every emptying medium and good sealing effect flat mouthful gate valve.
The purpose of this utility model is achieved in that the flat mouthful gate valve of a kind of separation, comprise valve body, flashboard and sealing pair, it is characterized in that the valve port on the valve body is that the bottom is semicircle a mouthful of plane, the flashboard bottom of sealing with matching is the plane, sealing pair on the flashboard is the special-shaped seal ring that is made of sealing one section plane and one section cambered surface two-part, forms the end sealing and the end between special-shaped seal ring and the valve body to seal.The one side of flashboard is the plane, and another side is the inclined-plane.
For reaching behind the valve opening the not purpose of residual medium of cabin, the bottom design of valve port is become the plane, in order to realize reliable sealing, sealing pair on the flashboard is designed to have the special-shaped seal ring of sealing on one section plane, form end sealing and two sealing surfaces of end sealing between sealing pair and the valve body, solved sealing problem preferably.One side with flashboard is designed to the inclined-plane simultaneously, and the inclined-plane is stressed to impel combining closely of sealing surface, further guarantees sealing effect.
Characteristics of the present utility model are: adopted the planar design of valve port bottom, can residual medium in the cabin during unloading, and can satisfy usage requirement.Simultaneously, the sealing of two sealing surfaces by sealing pair makes it have reliable sealing performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further auspicious stating:
As shown in Figure 1 and Figure 2, the valve body (1) of flat mouthful gate valve, its valve port (6) is semicircle mouthful of band bottom plane (7), valve body top is connected with semicircle valve gap (4), be positioned at sealing of valve body and be connected with valve rod (5) on the flashboard (2), one end of valve rod stretches out with driving mechanism through valve gap and is connected, and drives flashboard by it and moves up and down, and gate valve is opened or closed.The one side of flashboard is the plane, and another side is the inclined-plane, and the bottom is the plane, and sealing pair (3) is located on the plane of flashboard, and it is made of one section plane and one section cambered surface two-part, forms the special-shaped seal ring of a sealing.The plane of sealing pair and the junction of cambered surface should have higher design and machining accuracy, to guarantee the reliability of sealing.The shape of special-shaped seal ring can make and form the end sealing between itself and the valve body and the end seals.Flashboard is subjected to downwards and the effect of lateral force can make two sealing surfaces form good sealing.
Claims (2)
1, the flat mouthful gate valve of a kind of separation, comprise valve body, flashboard and sealing pair, it is characterized in that the valve port on the valve body is that the bottom is semicircle a mouthful of plane, the flashboard bottom of sealing with matching is the plane, sealing pair on the flashboard is the special-shaped seal ring that is made of sealing one section plane and one section cambered surface two-part, forms the end sealing and the end between special-shaped seal ring and the valve body to seal.
2, the flat mouthful gate valve of separation according to claim 1, the one side that it is characterized in that flashboard is the plane, another side is the inclined-plane.
