Description

3-way check valve for wastewater package {3-WAY CHECK VALVE FOR POOR DRAINAGE PACKAGE SYSTEM}

The present invention relates to a 3-way check valve for a wastewater package mounted on a discharge pipe of a wastewater package system, and more particularly, when fluid is supplied to the valve housing through one inlet, the check ball blocks the other inlet, Not only does it block the back flow of waste water, but the fluid is discharged through the discharge port, and when the fluid is simultaneously supplied to the inside of the valve housing through the first inlet and the second inlet, the check ball is placed in the center of the curved part of the guide lane by the fluid. , It relates to a 3-way check valve for sewage and drainage packages in which the fluid supplied through the first inlet and the fluid supplied through the second inlet are discharged through the outlet.

Korean Patent No. 10-2431585 (registered on August 8, 2022) of the present applicant introduces a "sewage package system preventing clogging by a strainer chamber".

The wastewater package system preventing clogging by the strainer chamber includes a sewage tank for storing sewage, a sewage pump installed inside the sewage tank to suction and discharge sewage, and separating foreign substances from the sewage flowing into the sewage tank. It includes a strainer chamber, the strainer chamber is a sewage inlet connected to the sewage pipe through which the sewage flows in the upper part of the strainer chamber, filtering foreign substances contained in the sewage flowing into the sewage inlet, the foreign matter in which the filtered foreign matter is located space, and a strainer portion dividing the sewage space in which the sewage filtered with foreign substances is located, and when the operation of the sewage pump is stopped, the fluid filtered from the foreign substances into the sewage tank flows into the sewage tank through the discharge port, and the sewage pump During operation, a pump connection unit connecting the discharge port of the sewage pump and the sewage space to drain the sewage from the sewage tank through the discharge port, and discharge the sewage together with the foreign matter located in the foreign matter space to the outside of the sewage tank. and a discharge connection portion connecting the foreign matter space and a discharge pipe for discharging the sewage.

However, in the wastewater package system preventing clogging by the strainer chamber, two strainer chambers are arranged in parallel, and when only one strainer chamber's wastewater pump is operating and the other strainer chamber's wastewater pump is stopped, the discharge pipe A 3-way check valve for preventing sewage containing discharged foreign substances from flowing back into the strainer chamber of the stopped sewage pump is not mentioned.

A "three-way valve" is introduced in Korean Patent Publication No. 10-1999-0038278 (published on June 5, 1999).

The three-way valve includes a passage blocking ball for controlling the flow of a passage in the three-way valve, and a protrusion for restricting the movement of the passage blocking ball is formed on the inlet side of the passage, respectively, and the outlet side of the passage has a diameter of the passage blocking ball. It is formed smaller than the diameter of the ball so that the flow blocking ball does not block the discharge port.

However, the 3-way valve has a disadvantage in that the fluid cannot be discharged because the flow blocking ball blocks the discharge port when fluid flows into the valve at the same time from the two inlet sides.

Therefore, an object of the present invention is that the valve housing is formed in a half-annular shape, the first inlet is disposed at one end of the valve housing, the second inlet is disposed at the other end of the valve housing, and A guide lane and a fluid induction chamber are formed, the fluid induction chamber is disposed on the upper part of the guide lane, a gap between the guide lane and the fluid induction chamber is opened, a check ball is disposed in the guide lane, and the outer side of the valve housing Since the outlet is formed in the middle of the circular arc, when the fluid flows into the first inlet, the check ball blocks the second inlet, so that the fluid supplied to the inside of the valve housing through the first inlet is discharged through the outlet, and into the second inlet. When fluid flows in, the check ball blocks the first inlet, and the fluid supplied to the inside of the valve housing through the second inlet is discharged through the outlet, and the fluid flows into the valve housing through the first and second inlets simultaneously. When supplied, a check ball is arranged in the center of the curved part of the guide lane by the fluid, and the fluid supplied through the first inlet and the fluid supplied through the second inlet are discharged through the discharge port. is to provide

In the 3-way check valve for wastewater package according to the present invention for achieving the above object, the valve housing is formed in a half-annular shape, the first inlet is disposed at one end of the valve housing, and the valve housing A second inlet is disposed at the other end, and a hollow is formed inside the valve housing, so that the hollow is divided into a guide lane and a fluid induction chamber, and the guide lane extends from the first inlet to the second inlet along the inner arc of the valve housing. It is formed to be curved up to the inlet, the fluid induction chamber is disposed on the upper part of the guide lane, the guide lane and the fluid induction chamber are opened, the guide lane and the fluid induction chamber are communicated, the check ball is disposed in the guide lane, and the check ball is placed in the guide lane. The ball moves along the guide lane to block the first inlet or the second inlet, and the discharge port is formed in the middle of the outer circular arc of the valve housing, and the discharge port is disposed at the midpoint of the fluid induction chamber.

The first inlet and the second inlet include a connection part connected to the valve housing and an auxiliary end pipe connected to the connection part,

The auxiliary end pipe is formed with a tapered ball seating portion having a gradually reduced diameter, a first flange formed around the front end of the ball seating portion is connected to the flange of the connecting portion, a straight pipe portion extends from the ball seating portion, and around the straight pipe portion It is characterized in that the second flange portion is formed.

The guide lane has a circular cross-section to accommodate the check ball, is formed in a circular shape curved along the shape of the valve housing, and has an opening formed at an upper portion of the circular cross-section to communicate with the fluid induction chamber.

The fluid induction chamber is characterized in that its volume increases from the first inlet and the second inlet toward the central discharge port.

In the 3-way check valve for wastewater package according to the present invention, the first inlet is connected to the first discharge pipe connected to the discharge port of the first sewage pump, and the second inlet is connected to the second discharge pipe connected to the discharge port of the second sewage pump. characterized by being connected.

Alternatively, in the 3-way check valve for a wastewater package according to the present invention, the first inlet of the valve housing is connected to the first discharge pipe of the first strainer chamber for the wastewater package, and the second inlet of the valve housing is a second strainer for the wastewater package It is characterized in that it is connected to the second discharge pipe of the chamber.

As a result, in the 3-way check valve for wastewater package according to the present invention, the check ball through which fluid is supplied to one inlet blocks the other inlet, thereby preventing sewage from flowing back to the other inlet, as well as preventing sewage containing foreign substances from flowing back to the other inlet. When the fluid is discharged through the outlet and simultaneously supplied into the valve housing through the first inlet and the second inlet, the check ball is disposed at the center of the curved part of the guide lane by the fluid, and the fluid supplied through the first inlet and the second inlet are separated. 2 It has the effect that the fluid supplied through the inlet is discharged through the outlet.
