Abstract

The utility model relates to a unidirectional drainage device. The utility model is characterized in that the utility model is provided with an outer shell whose upper part and lower part are communicated. The lower part of the outer shell is provided with a bracket, and a floating ball is arranged on the bracket. The upper end of the outer shell is provided with a reversal preventing cover whose center is provided with a circular hole, and the diameter of the circular hole is smaller than that of the floating ball. The utility model can only discharge water downwards in a unidirectional mode, which can effectively prevent the upward overflow of sewage. Besides, the utility model has the advantages of simple structure and low cost.

Description

The single slope drainage device

The utility model relates to a kind of single slope drainage device, particularly prevents the device of effluent sewerage overflow.

At present, the dewatering installation that existing resident family uses generally all is directly to feed drainage pipe, drainage inlet have be added with the deodorization bowl or water is curved, what have is added with the lid of combing, but all can not prevent the sewage overflow.When sewer pipe took place to stop up, regular meeting came up from the outfall of building bottom during sewage, seedling and bottom resident family.

The purpose of this utility model is that a kind of device that prevents sewer pipe sewage overflow will be provided.

The technical solution of the utility model is: this single slope drainage apparatus features is that a shell that communicates up and down (1) is arranged, one carriage (2) is arranged at the bottom in shell (1), carriage (2) is gone up and is placed a ball float (3), there is counnter attack lid (4) upper end in shell (1), and there is a circular hole (5) at counnter attack lid (4) center; The diameter of this circular hole (5) is less than the diameter of ball float (3).

Characteristics of the present utility model are that described counnter attack lid (4) can be connected threadably with shell (1).

Characteristics of the present utility model are that described counnter attack lid (4) is positioned on the bracket (6) of upper end in the shell (1), around the shell (1) of counnter attack lid (4) top is inboard, also have a spring card slot (7), a ring spring collar (8) is arranged in spring card slot (7) counnter attack lid (4) chucking.

Advantage of the present utility model and effect are: owing to adopt ball float and counnter attack lid structure, make this device can only single slope drainage, can prevent the sewage overflow effectively.This device also has advantage simple in structure, with low cost, that be easy to promote simultaneously.

Below in conjunction with accompanying drawing, the utility model is described further.

Fig. 1 is the utility model structural representation.

Fig. 2 is embodiment 2 structural representations.

Fig. 3 is the spring collar structure chart.

Fig. 4 is embodiment 3 structural representations.

Vertical view when Fig. 5 is the no counnter attack lid of Fig. 4.

Embodiment 1, as Fig. 1, this device is by the cylinder blanket that communicates up and down (1), three fin carriages (2) that are mutually 120 ° on the lower inner wall in the shell (1), carriage (2) is gone up the ball float of placing (3), upper end in the shell (1) is formed through the counnter attack lid (4) that is threaded, there is a circular hole (5) at counnter attack lid (4) center, the diameter of this circular hole (5) is less than the diameter of ball float (3), the lower end of the shell of this device (1) connects sewer pipe, circular hole (5) on the upper end lid of counnter attack just (4) of shell (1) is water inlet, when the circular hole (5) from counnter attack lid (4) when water is poured into, water enters in the shell (1), because carriage (2) holds up ball float (3), ball float (3) has enough spaces to make water flow into sewer pipe downwards with shell (1) inboard all around, and can not influence draining.Blocked when sewer pipe, the water level in the waterpipe rises gradually, in the time of will overflowing, ball float (3) is with water level come-up, floats circular hole (5) to counnter attack lid (4) when locating, and automatically circular hole (5) sealed, make sewage not overflow, promptly prevent the function that sewage overflows thereby finished single slope drainage.

Embodiment 2, as Fig. 2, there is a deodorization tank (11) the interior lower end of shell (1), one deodorization bowl (2) is arranged on the deodorization tank (11), and this deodorization bowl (2) is carriage, and deodorization bowl (2) is gone up and placed a ball float (3), counnter attack lid (4) is positioned on the bracket (6) of upper end in the shell (1), around the shell (1) of counnter attack lid (4) top is inboard, have a spring card slot (7), ring spring collar (a 8) (see figure 3) is arranged in spring card slot (7), with counnter attack lid (4) chucking.Its operating principle is identical with embodiment 1 with process, repeats no more.

Embodiment 3, and as Fig. 4, Fig. 5, the carriage of the interior bottom of shell (1) is two convex edges (2) that shell (1) inwall is received inwards, form the mouth of a river (10) under the strip between convex edge (2), and water can be that flow out downwards the both sides of ball float from the mouth of a river (10) under this strip.All the other structures of this example and the course of work are identical with last two embodiment.Present embodiment is fit to be installed between the following outfall and drainage pipe of pan or flush toilet.

Bend pipe among Fig. 4 (9) is the deodorization bend pipe of pan bottom.
