Abstract
The utility model relates to a gate valve of an impurity stay prevention structure. The gate valve of the impurity stay prevention structure comprises a valve body, a valve rod and a gate frame, wherein the gate frame is provided with a left gate and a right gate, and a disc-shaped spring is added between the left gate and the right gate. The disc-shaped spring is acted by pressure to deform, stores a certain amount of potential energy, can play excellent seal effect between abrasions of seal surfaces, and releases a certain amount of potential energy after the seal surfaces are abraded, thereby enabling the left gate and the right gate to be clung to the seal surfaces, and achieving seal effect.
Description
Technical field
The utility model relates to a kind of gate valve that stops structure with the anti-impurity of sealing surface.
Background technique
Its seal arrangement of gate valve that uses at present is the sealing that forms between sealing surface and the flashboard, and the adjusting pad of fixed size only is housed between the left and right flashboard, such device is after long-time the use, sealing surface is owing to friction causes the thickness attenuation, thereby cause forming between sealing surface and the flashboard certain gap, impurity easily snaps in sealing surface, damages sealing surface, loses the effect of sealing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gate valve that still can play sealing effect behind sealing surface wear.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a gate valve, comprise valve body, valve rod, flashboard frame, and the flashboard frame is equipped with in the valve rod lower end, and the flashboard frame is provided with left flashboard, right flashboard, is added with belleville spring between left flashboard and the right flashboard.
Adopt the gate valve of said apparatus, the effect of being stressed of belleville spring between the left and right flashboard is out of shape, save certain potential energy, after sealing surface wear, can play good seal action, behind sealing surface wear, belleville spring discharges certain potential energy, make left and right flashboard still can be close to sealing surface, thereby can also reach the effect of sealing.
Description of drawings
Fig. 1 is the structural drawing of gate valve of the present utility model.
Embodiment
By structural drawing shown in Figure 1 as can be known, there is an inner chamber valve body 1 inside, valve rod 5 stretches in the inner chamber of valve body 1, the lower end of valve rod 5 is connected with flashboard frame 7, flashboard frame 7 is fixed in the lower end that has a pin 8 to pass valve rod 5, flashboard frame 7 is provided with left flashboard 2, right flashboard 4, left flashboard 2 is close to respectively on the valve seat 9 with right flashboard 4, the right side horizontal plane of left flashboard 2 is hierarchic structure, the left side of right flashboard 4 has a blind hole can make the ladder surface of left flashboard just embed, be connected with between left flashboard 2 and the right flashboard 4 and regulate pad 6, respectively be added with belleville spring 3 at the two ends of regulating pad 6.
