Problems solved by technology

[0002] The current sewage valve, because the sealing structure of the valve stem and the valve seat is the same as that of the globe valve, when the valve is opened, a small gap is formed between the valve stem and the valve seat, and the high-speed fluid carries dross, causing damage to the sealing surface of the valve stem and the valve seat. Strong flushing, also when closing, damages the sealing surface and shortens the service life of the valve

Embodiment Construction

[0010] Depend on Figures 1 to 3 It can be seen that the present invention includes a handle assembly, a bracket assembly and a valve body assembly, wherein a stuffing box assembly is arranged between the bracket assembly and the valve body assembly, and a valve stem 3 is arranged in the stuffing box assembly, and the top end of the valve stem 3 is connected to the handle assembly through the bracket assembly, and the bottom is connected to the handle assembly. The valve stem sealing surface coincides with the fluid inlet sealing surface of the valve body assembly, and the valve stem 3 and the valve stem sealing surface are controlled by the bracket assembly and the handle assembly, and the valve stem sealing surface is pressed against the fluid inlet sealing surface of the valve body assembly to close the valve. , The sealing surface of the valve stem is separated from the sealing surface of the fluid inlet of the valve body assembly to open the valve.

Abstract

The invention relates to an angle type drain valve. The angle type drain valve comprises a handle component, a support component and a valve component, wherein a packing box component is arranged between the support component and the valve component; the packing box component is internally provided with a valve rod; the top end of the valve rod is connected with the handle component by the support component; the bottom end of the valve rod is provided with a valve rod sealing surface matched with a valve component fluid inlet sealing surface; the valve rod and the valve rod sealing surface are controlled by the support component and the handle component; the valve rod sealing surface and the valve component fluid inlet sealing surface are tightly compressed so that the valve is closed; and the valve rod sealing surface and the valve component fluid inlet sealing surface are separated so that the valve is opened. With the adoption of the angle type drain valve, the direct scouring of a high-speed fluid and residues is avoided; and at the same time, an eddy zone with a pressure more than that of the fluid centre is generated when the high-speed fluid flows near a socket close to the valve sealing surface, and the eddy zone is more in favour of preventing the high-speed fluid from closing to the valve sealing surface, so that the scouring of the high-speed fluid and the residues on the valve sealing surface is further avoided.

Description

technical field [0001] The invention relates to a valve, in particular to an angle-type blowdown valve suitable for industries such as petroleum, chemical industry and thermal power. Background technique [0002] The current sewage valve, because the sealing structure of the valve stem and the valve seat is the same as that of the globe valve, when the valve is opened, a small gap is formed between the valve stem and the valve seat, and the high-speed fluid carries dross, causing damage to the sealing surface of the valve stem and the valve seat. Strong flushing, also when closing, causes damage to the sealing surface and shortens the service life of the valve. Contents of the invention [0003] The object of the present invention is to improve and innovate on the defects and problems existing in the background technology, and to provide an angle-type sewage valve with novel structure, anti-scouring and long service life. [0004] The technical solution of the pre...
