Abstract

The utility model discloses a running water is drawn water and is used check valve, including the drinking-water pipe, the one end of drinking-water pipe is the water inlet, water inlet medial segment is provided with the multi-disc and turns over the board, and every turns over the both ends of board and rotates through the pipe wall that turns over board pivot and drinking-water pipe and be connected, the multi-disc turn over the board and laminate each other between adjacent, the multi-disc turn over the relative direction upset of board to the water inlet, the multi-disc turn over the board cover the water. Compared with the prior art, the utility model discloses a multi-disc turns over plate structure's design for rivers resistance is low when passing through the check valve, and it is big to pass through the water yield, and turns over the board and adopt the arc structure, can make to turn over the board and in time overturn and close the water inlet under the condition of rivers retrograde motion, and the reaction is sensitive, has the value of popularization and application.

Description

Check valve for pumping tap water

Technical Field

The utility model relates to a pumping device especially relates to a running water is pumped water and is used check valve.

Background

The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. Check valves are also known as check valves or check valves. For preventing reverse flow of oil in hydraulic systems or for preventing reverse flow of compressed air in pneumatic systems. The one-way valve has a straight-through type and a right-angle type. The straight-through one-way valve is installed on the pipeline by threaded connection. The right-angle check valve has three forms of threaded connection, plate connection and flange connection. Most of the prior art check valves for pumping tap water are one-way valves with a rubber circular plate, but the size of the rubber circular plate is close to the inner diameter of a pumping pipe, so that the check valve has low water passing amount and large resistance, and therefore, the check valve has space for improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provide a check valve for pumping tap water.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model discloses a drinking-water pipe, the one end of drinking-water pipe is the water inlet, water inlet medial segment is provided with the multi-disc and turns over the board, and every turns over the both ends of board and rotates through the pipe wall that turns over board pivot and drinking-water pipe and be connected, the multi-disc turn over and laminate each other between the board is adjacent, the multi-disc turn over the relative direction upset of board to the water inlet, the multi-disc turn over the board cover the water inlet.

Preferably, the plurality of turning plates form a rectangular structure, and the rectangular structure formed by the plurality of turning plates covers the water inlet.

Preferably, the turning plate and the water inlet are in an arc structure in the opposite direction.

Preferably, the turnover angle of the turning plate is smaller than 90 degrees.

Preferably, the rectangular structure formed by the plurality of turning plates is obliquely arranged in the water pumping pipe.

The beneficial effects of the utility model reside in that:

the utility model relates to a running water is drawn water and is used check valve, compare with prior art, the utility model discloses a multi-disc turns over plate structure's design for rivers resistance is low when passing through the check valve, and is big through the water yield, and turns over the board and adopt the arc structure, can make to turn over the board and in time overturn and close the water inlet under the condition of rivers retrograde motion, and the reaction is sensitive, has the value of popularization and application.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 to 3: the utility model discloses a drinking-water pipe 1, the one end of drinking-water pipe 1 is

water inlet

2, 2 interior sections of water inlet are provided with the multi-disc and turn over board 3, and every turns over the both ends of board 3 and rotates through the pipe wall that turns over board pivot 4 and drinking-water pipe 1 and be connected, the multi-disc turn over and laminate each other between board 3 is adjacent, the multi-disc turn over board 3 and overturn to the relative direction of water inlet, the multi-disc turn over board 3 and cover water inlet 2.

Preferably, the turning plates 3 form a rectangular structure, and the rectangular structure formed by the turning plates 3 covers the water inlet 2.

Preferably, the turning plate 3 and the water inlet 2 are in an arc structure in opposite directions.

Preferably, the turning angle of the turning plate 3 is smaller than 90 degrees.

Preferably, the rectangular structure formed by the plurality of turning plates 3 is obliquely arranged in the water pumping pipe 1.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
