Embodiment Construction

[0028] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0029] As shown in the figure, a U-shaped gate valve includes a valve body 1, a valve stem 2, a valve plate 3 and a valve seat 4, the valve body 1 and the valve seat 4 clamp the valve plate 3 together, and the valve The plate 3 is U-shaped, and an elastic member is provided between the valve plate 3 and the valve body 1 to provide the thrust required for the sealing fit between the valve plate 3 and the valve seat 4. The elastic member includes several U-shaped arrangements installed on the The first elastic member 5 on the valve body 1, the first elastic member 5 is tubular and has a gap 51 along the length direction, and the valve body and the valve seat are connected by a movable adjustable connection. The first elastic part adopts a pipe with a notch, and when it is squeezed by an external force, it will deform and generate an external elastic force, and...

Abstract

The invention discloses a U-shaped gate valve, which relates to the field of valves. It includes a valve body, a valve stem, a valve plate and a valve seat. The valve body and the valve seat jointly clamp the valve plate, and the valve plate is U-shaped. , between the valve plate and the valve body, there is an elastic member that provides the thrust required for the sealing cooperation between the valve plate and the valve seat, and the elastic member includes a plurality of first elastic members installed on the valve body in a U-shaped arrangement , the first elastic member is tubular and is provided with a gap along the length direction, and the valve body and the valve seat are connected in a movable and adjustable manner. The present invention has the advantages of good working stability.

Description

technical field [0001] The invention relates to the field of valves, in particular to a U-shaped gate valve. Background technique [0002] In the prior art, there are no U-shaped sealing gate valves and valves. Existing valves are all round or square, and square valves are allowed to leak to a certain extent. The current situation is that the design institute requires a U-shaped sealing valve to solve the interception and diversion of the U-shaped transport tank in the production process of mineral fertilizers. In the past, when there was no U-shaped valve, it was necessary to connect two special-shaped valves to the U-shaped tank. The U-shaped tube is changed into a round shape. The process of this special-shaped tube is immature, and problems often occur during use, and the cost of two special-shaped tubes is also high. Therefore, the design institute puts forward the requirements for valve enterprises to design sealed U-shaped valves. However, the sealed U-shaped valve ...
