Abstract

The invention discloses an upper mounting type butterfly valve. The upper mounting type butterfly valve comprises a valve body, a valve cover arranged on the top of the valve body, a valve rod tightly inserted on the valve cover and with the bottom extending into a valve body mounting groove, a butterfly plate fixed on the bottom of the valve rod, a sealing valve base arranged on an inlet of the valve body, and a limiting component coating the valve rod and used for enabling the valve rod to only perform a rotating motion in the horizontal direction. When all parts of the butterfly valve are mounted, the valve rod and the component of the butterfly plate are only required to be inserted in a cavity of the valve body, the limiting component coats the valve rod, and the valve rod is fixed on the top of the valve body; when the butterfly valve is used and installed with other equipment, a reserved space has no need to be formed below the mounting position of the butterfly valve, and the installation is directly performed; and when the butterfly valve is required to be disassembled and maintained, the disassembly procedure and the installation procedure are opposite, so that the installation and maintenance procedures of the butterfly valve are simplified, and the working efficiency is improved. Meanwhile, the limiting component enables the sealing performance between the valve rod and the butterfly plate to become better; and the service life of the butterfly valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a top-mounted butterfly valve. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief, etc., and can be widely used in delivery devices for compressible or incompressible media. Among them, the butterfly valve is an important type of valve, which can be widely used in medium conveying devices. The cut-off or conduction of the butterfly valve is mainly realized by the rotation of the valve stem to drive the rotation of the butterfly plate. [0003] The structure of the top entry butterfly valve in the prior art is mostly as figure 1 As shown, it includes a valve body 1, the valve body 1 has a cavity for medium circulation, the cavity has an inlet and an outlet, and installation holes are s...
