Problems solved by technology

The swing check valve is a commonly used check valve. The cut-off direction of the swing check valve in the prior art is fixed after the installation is completed. If the cut-off direction needs to be changed (such as the direction of the swing check valve In case of accidental reverse installation), the swing check valve needs to be dismantled and reinstalled after reversing the direction, which is very inconvenient

Embodiment Construction

[0024] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0025] Such as figure 1 As shown, a swing check valve corresponding to a preferred embodiment of the present invention includes a valve body 10, a valve cover 30 and a valve clack assembly.

[0026] The valve body 10 includes a water inlet 11 , a water outlet 12 , an inner chamber 13 located between the water inlet 11 and the water outlet 12 , and an opening 14 located at the top of the valve body 10 and communicating with the inner chamber 13 . The water inlet 11 is used for medium inflow, which is connected to the water inlet pipe, and the valve body 10 is provided with a first flange connection 15 at the water inlet 11; the water outlet 12 is used for medium outflow, which is connected to the water outlet pipe, and the valve body 10 A second flange connection 16 is provided at the water outlet 1...

Abstract

The invention discloses a swing check valve comprising a valve body (10), a valve cover (30) connected with the valve body (10), and a valve flap assembly arranged in the valve body (10). The swing check valve further comprises a first valve seat (18) and a second valve seat (19) which are symmetrically arranged in the valve body (10). The valve flap assembly comprises a handle (62), a connectingcolumn (51) connected with the handle (62), and a valve flap (52) rotationally connected with the connecting column (51). The connecting column (51) is rotationally connected with the valve cover (30). The valve flap (52) can seal the first valve seat (18), and after the handle (62) rotates by a certain angle, valve flap (52) can seal the second valve seat (19). The valve flap assembly rotationally connected with the valve cover so that the valve flap assembly can seal the symmetrically arranged valve seats after the handle is rotated, thus the stop direction of the check valve is changed, andoperation is simple.

Description

technical field [0001] The invention relates to a check valve, in particular to a swing check valve. Background technique [0002] Check valves are used to prevent backflow of media in pipelines. When the medium in the pipeline flows forward, the disc of the check valve automatically opens under the action of the medium force, and when the medium in the pipeline flows in the reverse direction, the valve disc automatically closes under the action of the medium force. The swing check valve is a commonly used check valve. The cut-off direction of the swing check valve in the prior art is fixed after installation. If it is necessary to change the cut-off direction (such as the direction of the swing check valve In the case of accidental reverse installation), the swing check valve needs to be dismantled and reinstalled after reversing the direction, which is very inconvenient. Contents of the invention [0003] The object of the present invention is to solve the above-mentio...
