Abstract

The utility model discloses a reinforced type drainage sound-absorbing fitting. The reinforced-type drainage sound-absorbing fitting is in the shape of a truncated cone with a large upper end and a smaller lower end. Two groups, namely the first group of diversion ribs and the second group of diversion ribs, the height of the first group of diversion ribs is greater than that of the second group of diversion ribs, the width of the first group of diversion ribs is greater than that of the second group of diversion ribs ; The diversion rib is consistent with the drainage direction, that is, it is wide at the top and narrow at the bottom. Setting reinforcing ribs on the outer surface of the fittings can effectively improve the ring stiffness and negative pressure resistance of the fittings, and setting diversion ribs on the inner surface of the fittings, and the direction of the diversion ribs is consistent with the direction of the water flow, and the diversion ribs make the collected drainage generate swirl , to accelerate drainage, but also to separate water and air, reducing positive and negative pressure fluctuations. The diversion ribs are in the same direction as the drainage, which can minimize the flow of water from rushing out of the diversion ribs. When the water flows together, it can generate swirling flow and increase the drainage flow, thereby achieving the effect of noise reduction.

Description

A reinforced drainage sound-absorbing fitting

technical field

The utility model relates to a connection fitting used in a drainage system, in particular to a reinforced drainage sound-absorbing fitting.

Background technique

During the drainage process of the drainage pipeline system, large vibrations are often generated at the confluence of the joints due to interruption of water flow and redirection of the flow direction, which will cause positive and negative pressure fluctuations in the drainage pipeline, damage the water seal, and affect the drainage capacity. , At the same time, it also produces a lot of noise, which makes the residents suffer from noise.

There are some accessories with guide vanes in the market. The shape of the blades is designed to be spiral, and it is at a certain angle to the drainage direction. In the actual drainage process, when the water in the drain pipe falls on the guide vanes, a large The impact force, because there are more impurities in the drainage, will cause greater damage to the guide vanes, and it will be easily worn and disappeared under long-term work, thus losing the diversion effect.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcomings, and propose a utility model of a reinforced drainage sound-absorbing fitting. This fitting is mainly used in the drainage system. On the premise of meeting the requirements of building drainage, it can improve the drainage flow and reduce the noise of running water.

For solving the problems of the technologies described above, the technical scheme of the utility model is as follows:

A reinforced type drainage sound-absorbing fitting, the outer surface of the reinforced-type drainage sound-absorbing fitting is provided with reinforcing ribs, and the inner surface is provided with diversion ribs, and the direction of the diversion ribs is consistent with the drainage direction. The reinforcing ribs can effectively improve the ring stiffness of the fittings; the diversion ribs make the collected drainage generate swirling flow, accelerate drainage, and also separate water and air, reducing positive and negative pressure fluctuations. The diversion ribs are in the same direction as the drainage, which can minimize the flow of water from rushing out of the diversion ribs. When the water flows together, it can generate swirling flow and increase the drainage flow, thereby achieving the effect of noise reduction.

Further, the diversion ribs are divided into two groups, namely the first group of diversion ribs and the second group of diversion ribs, the height of the first group of diversion ribs is greater than that of the second group of diversion ribs, the first group of diversion ribs The width of the diversion rib is greater than that of the second group of diversion ribs.

Further, the reinforced drainage sound-absorbing fitting is in the shape of a frustum with a large upper end and a smaller lower end. The shape is set in the shape of a cone, which can play the role of drainage and collection

In order to eliminate the water flowing in from multiple branch pipes, the reinforced drainage silencer fittings can be combined with other fittings to form multi-channel fittings such as straight-through, three-way, four-way, five-way, etc., which can strengthen the swirling flow, Produce water and air separation to improve drainage flow.

Compared with the prior art, the beneficial effect of the technical solution of the utility model is that: setting reinforcing ribs on the outer surface of the fittings can effectively improve the ring stiffness and anti-negative pressure ability of the fittings, and setting guide ribs on the inner surface of the fittings, and guiding The ribs are in the same direction as the water flow, and the diversion ribs make the collected drainage generate swirling flow, accelerate drainage, and also separate water and air, reducing positive and negative pressure fluctuations. The diversion ribs are in the same direction as the drainage, which can minimize the flow of water from rushing out of the diversion ribs. When the water flows together, it can generate swirling flow and increase the drainage flow, thereby achieving the effect of noise reduction.

Detailed ways

The technical scheme of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

As shown in Fig. 1, a kind of reinforced drainage sound-absorbing accessories, the reinforced-type drainage sound-absorbing fittings are in the shape of a truncated cone with a large upper end and a smaller lower end, the outer surface is provided with reinforcing ribs 3, and the inner surface is provided with diversion ribs, and the diversion ribs are Two groups, namely the first group of diversion ribs 2 and the second group of diversion ribs 1, the height of the first group of diversion ribs 2 is greater than that of the second group of diversion ribs 1, the width of the first group of diversion ribs 2 is greater than that of the second group Two sets of diversion ribs 1; the diversion ribs are consistent with the drainage direction, that is, the top is wide and the bottom is narrow.

Apparently, the above-mentioned embodiments of the present utility model are only examples for clearly illustrating the present utility model, rather than limiting the implementation manner of the present utility model. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description.
