Description

Effectual check valve of silence

Technical Field

The utility model relates to the technical field of check valves, in particular to a check valve with a good silencing effect.

Background

The check valve is a valve whose opening and closing piece is a circular valve clack and can be actuated by self weight and medium pressure to block medium backflow, and belongs to the field of automatic valves.

The check valve can be installed for better control of the flowing direction or flow control in the water pipe, the phenomenon that water in the pipe flows back after the pipe is closed is avoided, but the existing check valve can generate noise when being closed due to water flow when in use, and the internal structure can cause abnormal sound due to mutual friction when being closed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a check valve with good silencing effect, and aims to solve the problems that the existing check valve generates noise when being closed due to water flow when in use and abnormal noise is caused by mutual friction when the internal structure is closed.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an effectual check valve of silence, includes the valve casing, be provided with the cylinder in the valve casing, first spout has been seted up in the valve casing, be provided with in the first spout and press the pipe, press the pipe upper end through first spout and cylinder fixed connection, it is provided with the sponge board to press one side of pressing, it is provided with the clamp plate to press the pipe lower extreme, the clamp plate lower extreme is provided with the rubber block, be provided with soundproof cotton in the valve casing.

Through adopting above-mentioned technical scheme, set up soundproof cotton in the valve casing can effectual reduction most noise, when ending rivers for the guarantee simultaneously, because water can be because of inertia backward flow directly clashes into to press to cause the noise on the pipe, consequently having set up the pressure that the sponge board can slow down the striking on the one side that faces the pipeline pressing the pipe, secondly the hydroscopicity through the sponge board reduces the sound of water impact on the one hand.

Furthermore, a detection port is formed in the upper end of the valve shell, and the rubber block is in a convex shape.

Through adopting above-mentioned technical scheme, the inspection opening is convenient for the later stage and is maintained.

Further, the sponge board rear end is provided with the slide, press to open in the pipe and be equipped with the second spout, be provided with the spring of three equidistance distribution in the second spout, three spring and slide.

Through adopting above-mentioned technical scheme, the sponge board can retrieve to the second spout under the effect of spring when receiving the striking of water backward flow under the slide drive of rear end, thereby plays absorbing effect and reaches the cushioning effect.

Further, an opening is arranged in the valve shell and is matched with the rubber block.

Through adopting above-mentioned technical scheme, the rubber block blocks mutually with the opening and can effectual reduction spare part and the pipeline inner wall direct contact abnormal sound that the friction produced.

Compared with the prior art, the utility model has the beneficial effects that:

1. this effectual check valve of silence can effectual reduction most noise through set up soundproof cotton in the valve casing, when ending rivers for the guarantee simultaneously, because water can be because of inertia backward flow directly clashes into to press to cause the noise on the pipe, consequently pressing the pipe and having set up the pressure that the sponge board can slow down the striking on the one side of pipeline, secondly the hydroscopicity through the sponge board reduces the sound of water impact.

2. This effectual check valve of silence through the sponge board under the slide drive of rear end, can retrieve to the second spout under the effect of spring when receiving the striking of water backward flow, thereby plays absorbing effect, sets up the abnormal sound that the rubber block blocked mutually with the opening and can effectual reduction spare part and pipeline inner wall direct contact friction production.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, an embodiment of the present invention is shown: the utility model provides a effectual check valve of silence, including valve casing 1, be provided with cylinder 2 in the valve casing 1, first spout 3 has been seted up in the valve casing 1, be provided with in the first spout 3 and press pipe 4, press the pipe 4 upper end through first spout 3 and cylinder 2 fixed connection, press pipe 4 one side to be provided with sponge board 5, it is provided with clamp plate 6 to press the pipe 4 lower extreme, clamp plate 6 lower extreme is provided with rubber block 7, be provided with soundproof cotton 8 in the valve casing 1, detection mouth 9 has been seted up to valve casing 1 upper end, 7 types on rubber block, sponge board 5 rear end is provided with slide 10, press pipe 4 and seted up second spout 11, be provided with the spring 12 of three equidistance distribution in the second spout 11, three spring 12 and slide 10, be provided with opening 13 in the valve casing 1, opening 13 is identical with rubber block 7, can effectual reduction most noise through set up soundproof cotton 8 in valve casing 1, press the rubber block 7 that pipe 4 lower extreme set up mutually block and can effectual reduction spare part and pipeline inner wall direct with opening 13 card and can effectually reduce spare part The abnormal sound that contact friction produced, simultaneously when ending rivers in order to ensure, because water can be because of inertia backward flow directly strikes and causes the noise on pressing pipe 4, consequently pressing pipe 4 to set up the pressure that sponge board 5 can slow down the striking on the one side of pipeline, secondly the sound of water impact is reduced to the hydroscopicity through sponge board 5, and sponge board 5 drives down at the slide 10 of rear end, can retrieve to second spout 11 under spring 12's effect when the striking that receives the water backward flow, thereby play absorbing effect and reach cushioning effect.
