Ｉｌを維持し―い不都合があった。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a plate-shaped valve body equipped with a tth fluid flow hole that opens the valve box gate flow FjlI so as to be slidable in a direction substantially orthogonal to the flow Fjll, a pair of annular sorting contacts the outer surface of the valve body, and a pair of annular sorting contacts on the outer surface of the valve body so as to close a portion of the fluid flow hole located on the valve body storage chamber side in the middle open state. A pair of integral covers are attached to the valve box in contact with each other.Regarding the gate valve: By providing a pair of integral covers, such a gate valve can be used satisfactorily even for fluids containing powder. However, if the conventional structure is used, for example, as shown in FIG. A seat is connected so that it can slide integrally in a direction substantially perpendicular to the inner flow path a, and a seat that can freely slide integrally.
Porto cnt-, which presses to operate the 0 and 2-las slide integrated with the cover, is installed next to the valve box, and the seat screams)
and cover integrated - (c) along with the sliding of the valve body -
Since the cam surface e'6t-1 is provided on the valve box 181, it is troublesome to operate the bolts due to wear, and when used with high temperature fluid, It is actually important to operate the bolt properly in response to expansion, so always ensure proper sealing!
There was an inconvenience in maintaining Il.
本発明の目的目、特別な操作を要することなく、両環状
シート及び両力バ一体を弁体に対して常に適正状總で接
触さ才ることができるようにする点にある。An object of the present invention is to enable both annular seats and both force bars to be brought into contact with the valve body in an appropriate state at all times without requiring special operations.

わに付勢するスプリング４１けである。A characteristic configuration of the present invention is that a pair of annular seats (1) in contact with the outer surface of the cylinder of the valve body are supported so as to be able to move toward and away from each other, and a spring is provided to bias both the annular seats toward each other. The spring 41 supports a pair of covers that are in contact with the outer surface of the cylinder so that they can move toward and away from each other, and urges both covers to fully approach each other.
次に、本発明構成による作用効果を述べる。Next, the effects of the configuration of the present invention will be described.

に使用することが可能な仕切弁を得るに至つ之。That is, both annular seats and both force bars can be moved to a position where they contact the valve body in an appropriate state according to wear and thermal expansion by the action of the spring. Therefore, the valve body can always be brought into contact with both annular seats and both force bars in a proper state without requiring any special operation, thereby obtaining a gate valve that can be used more conveniently. That's it.
