Problems solved by technology

[0002] The swing check valve is the most common and the most widely applicable check valve. It is widely used, but it has the following defects: the opening and closing space of the swing check valve is large, so the closing water of the swing check valve every time it is closed The hammer is very large, damages the pumping station or the pipeline, and is easy to block
At the same time, the opening of the disc is not adjustable

Abstract

The invention relates to a rotary interception swing check valve, and belongs to the technical field of control devices on medium pipelines. The rotary interception swing check valve comprises a valve body, a valve cover arranged on the valve body, a valve shaft arranged at the upper end in the valve body and close to one end of a water inlet, and a valve clack fixedly connected to the valve shaft, wherein the water inlet end of the valve body is provided with a valve base sealed together with the valve clack; the valve shaft is sleeved with a transmission sleeve; the two ends of the valve shaft extend out of the valve body; one end is sealed together with the valve body, and the transmission sleeve at the other end is fixedly connected with the output end of a limiting driving device. The rotary interception swing check valve has an interception (current-regulating) function, the upper part of the valve cover is provided with the limiting driving device, and the opening of the valve can be adjusted through the limiting driving device; reliable and adjustable damping is realized through an automatic damping device, and the problem of water hammer is solved. Meanwhile, the rotary interception swing check valve has the characteristic of blocking resistance.

Description

technical field [0001] The invention belongs to the technical field of control devices on medium pipelines, and in particular relates to a rotary shut-off and spin-up check valve. Background technique [0002] The swing check valve is the most common and the most widely applicable check valve. It is widely used, but it has the following defects: the opening and closing space of the swing check valve is large, so the closing water of the swing check valve every time it is closed Hammers are large, damage pumping stations or pipelines, and are prone to clogging. At the same time, the opening of the disc is not adjustable. Contents of the invention [0003] The object of the present invention is to provide a rotary shut-off and swing-up check valve aiming at the defects of the prior art. [0004] The technical scheme adopted by the present invention is: comprising a valve body, a valve cover arranged on the valve body, a valve shaft arranged at the upper end of the valve bo...
