Abstract
The utility model discloses a sewage pipe joint, in particular to a leaf swirl drainage diversion joint which can avoid the odour return and the blockage of a sewage pipe. The leaf swirl drainage diversion joint is composed of a pipe body. Two diversion sheets are arranged in the pipe body, are arranged from up to down, and are of a willow leaf shape. The leaf surface part of each diversion sheet is of an inner sunken streamline curved surface which changes the direction of the flow to cause the flow to run down in the pipe body rotationally. Because the drainage is carried out by a single pipe, the leaf swirl drainage diversion joint has the advantages of little occupied space, low cost and convenient construction maintenance. When in drainage, the positive pressure and the negative pressure in the pipe are stable, thereby solving the problem that peculiar smell returns upward. The use of a diversion pipe can cause the noise to be lowered between 30DB and 40DB to have lower standard value than that of the prior thread hush pipe (GB has the regulation of 40DB to 45DB). The pipe body adopts antirust coating both the inner thickness and the outer thickness of which are 0.8mm, and an interface connecting part adopts a good NBT seal ring, so the service life is long, and the sealing performance is good.
Description
Technical field
The utility model is a kind of sewage pipe joint, the particularly a kind of blade eddy flow draining water conservancy diversion joint that can avoid sewage pipe back foul, obstruction.
Background technique
Drainage system in the existing tall building (more than 20 layers) uses two-tube drainage system more, and wherein a pipeline is a breathing pipe.Existing tall building drainage system needs drainage exhaust two circuits, and it is big to take up room, and construction is complicated, the cost height; Because the normal discharge system positive and negative pressure unstable problem that uses is general at present, particularly owing to the water in the water seal in the excessive toilet floor drain that causes of negative pressure is made the problem of returning on the peculiar smell after taking away; Draining noise is big, even the screw thread hush pipe, draining noise is also more than 40DB, and the common tube noise is higher; It is bad that the antirust processing of present most drain cast iron pipe is done, and uses just to have become rusty in the near future, and working life is short.
Summary of the invention
The defective that the purpose of this utility model is that existing sewage pipe construction is complicated, cost is high in order to overcome, return peculiar smell, noise is big does not need to establish separately outlet pipe and saves cost, construction blade eddy flow draining water conservancy diversion joint easy to maintenance thereby invention is a kind of.
The purpose of this utility model realizes as follows: described blade eddy flow draining water conservancy diversion joint, comprise a body, body inside is provided with two guide plates, this two guide plate is up and down, and both sides distribute, the guide plate shape is wicker leaf shape, and the blade face part of guide plate all is indent streamline curved surface, and this curved surface will change the direction of current, makes current in body under the rotating flow.
Described guide plate angle of inclination is: go up guide plate and horizontal angle at 45 degree---in the scope of 60 degree; Following guide plate and horizontal angle are at 55 degree---in the scope of 70 degree.To account for the ratio of whole body length be 50% to distance between two guide plates up and down---70%.
Be provided with rust preventive painting inside and outside the described body, the interface joint is provided with seal ring.
Good effect of the present utility model is as follows: owing to be the single tube draining, so it is little to take up room, cost is low, and it is easy to maintenance to construct; During draining in the pipe positive and negative pressure stable, remain at-between 40mm leans on to+40mm tribute, solved the problem of returning on the peculiar smell; Use this honeycomb duct, can make dry sound drop to 30DB, than present screw thread hush pipe specified standard value also low (the GB regulation is that 40DB is to 45DB) between the 40DB; Body has adopted inside and outside thickness to be the rust preventive painting of 0.8mm, and better NBR seal ring has been adopted in the interface joint, so longer service life, sealability is better.

Among the figure: 1 body, 2 guide plates, 3 seal rings
Embodiment
As shown in Figure 1, described blade eddy flow draining water conservancy diversion joint, comprise a body 1, body 1 inside is provided with two guide plates 2, this two guide plate 2 is both sides distribution up and down, and guide plate 2 shapes are wicker leaf shape, and the blade face part of guide plate 2 all is indent streamline curved surface, this curved surface will change the direction of current, make current in body 1 under the rotating flow.
Described guide plate 2 angles of inclination are: go up guide plate and horizontal angle at 45 degree---in the scope of 60 degree; Following guide plate and horizontal angle are at 55 degree---in the scope of 70 degree.To account for the ratio of whole body length be 50% to distance between two guide plates up and down---70%.
Be provided with rust preventive painting inside and outside the described body, the interface joint is provided with seal ring 3.
Be sewage to be carried out water conservancy diversion during draining by two guide plates that body inside distributes up and down, current are dumped downwards along the inner concave of guide plate, make current be close to the tube wall backspin, impact force of water flow is increased, and foreign material can not adhere on blade or the pipeline under water impact in the water, can not form obstruction, and current form hollow shape under the backspin effect, inner air tube is discharged along hollow space, and like this, single tube just can be realized drainage exhaust.
