Abstract
The utility model relates to a check valve with a float for a sewage, which is composed of a valve body, a float and a plug. The valve body is a hollow casing forming a float chamber, and is provided with an upper through hole, a lower through hole and a side through hole which are communicated with the float chamber. The joining points of the upper and the lower through holes and the float chamber form an upper and a lower valve seats. The diameter of the float is larger than the diameters of the upper and the lower through holes and is smaller than the distance between the upper and the lower valve seats and the diameter of the side through hole. The plug is arranged at the end of the side through hole. The utility model has the advantages of good sealing effect, no easy blocking and convenient dredging. Sewerage and odour can be prevented from overflowing.
Description
The utility model belongs to the sewerage accessory, particularly a kind of sewerage float type safety check.
At present, up for preventing sewerage foul smell, foul smell takes place to escape, usually trap is being set below the sanitary equipment and between the pipeline, to constitute water seal.This structure can't prevent not only that the foul smell of sewage and dirt escapes in the water seal, face and mediation takes place to stop up and be not easy to easily, and particularly when sewerage stops up, sewage outflow, befouling environment.
The purpose of this utility model provides a kind of good sealing effect, is difficult for stopping up, being convenient to mediation, and can prevent the sewerage float type safety check of sewage outflow.
The utility model is made up of valve body, float and obstruction, and valve which is provided with the last through hole, lower through-hole and the side through hole that connect with float chamber as the hollow casing that constitutes float chamber, and upper and lower through hole and float chamber joining place constitute upper and lower valve seat; Float is the ball valve of proportion less than water, its diameter is greater than the diameter of the upper and lower through hole on the valve body and less than the distance between the upper and lower valve seat on the valve body, and corresponding with the side through hole on the valve body, float places in the float chamber, and can be movable in float chamber and in the side through hole; Stop up corresponding and be installed in side through hole end on the valve body with releasable connection with the side through hole on the valve body.
Because the utility model is made up of valve body, float and obstruction, valve body which is provided with the upper and lower through hole and the side through hole that connect with float chamber for constituting the hollow casing of float chamber, and upper and lower through hole and float chamber joining place constitute upper and lower valve seat; The diameter of float reaches less than the distance between the upper and lower valve seat on the valve body greater than the diameter of the upper and lower through hole on the valve body, and corresponding with the side through hole on the valve body, and float places in the float chamber, and can be movable in float chamber and in the side through hole; Obstruction is installed in the side through hole end.During use, the upper and lower through hole end of valve body is connected with the following outlet of sanitary equipment and the entry end of sewerage respectively.Under normal state, float is positioned on the lower valve base under the self gravitation effect, the lower through-hole that sealing is connected with sewerage, and the sealing sewerage prevents the sewage of sewerage and the foul smell of dirt to escape; Under the bath state, impact force of water flow dashes float from lower valve base, and the approaching side through hole is opened lower through-hole, and current pour sewerage with the dirt in the sanitary equipment through lower through-hole; When sewerage stops up, float floats in the last sewage that emits, until being against on the upper valve base, the last through hole that sealing is connected with sanitary equipment, emit the foul smell of sewage and dirt to escape in the prevention, and can pull down obstruction, be convenient to mediation through last through hole, face and can prevent sewage outflow, thus reach the purpose of this real model utility.

Below in conjunction with accompanying drawing the utility model is further elaborated.
As Fig. 1, shown in Figure 3, the utility model is by valve body 1, float 2 and stop up 3 and form, valve body 1 is for constituting the hollow casing of float chamber 11, which is provided with last through hole 12, lower through-hole 13 and the side through hole 14, upper and lower through hole 12,13 and float chamber 11 joining places that connect with float chamber 11 and constitute upper and lower valve seat 15,16, side through hole 14 external end heads are provided with internal thread 17; As shown in Figure 2, valve body 1 can constitute an integral body with sitting posture or squat toilet 41; Float 2 is the ball valve of proportion less than water, is preferably hollow baton round, and its diameter reaches less than the distance between the upper and lower valve seat on the valve body 1 15,16 greater than the diameter in the hole, upper and lower road 12,13 on the valve body 1, and corresponding with the side through hole on the valve body 1; One end of obstruction 3 is the stopper 31 that is provided with outside thread 311, and its other end is a gag 32; The internal thread 17 in week and 311 engagements of the outside thread on the stopper 31 in side through hole 14 outer ends on the valve body 1.
As shown in Figure 1, during use, upper and lower through hole 12,13 ends of valve body 1 are connected with the following outlet of sanitary equipment 4 and the entry end of sewerage 5 respectively.Under normal state, float 2 is positioned on the lower valve base 16 under the self gravitation effect, the lower through-hole 13 that sealing sewerage 5 connects, and sealing sewerage 5, the sewage in the prevention sewerage 5 and the foul smell of dirt escape; As shown in Figure 4, under the bath state, impact force of water flow dashes float 2 from lower valve base 16, and approaching side through hole 14 is opened lower through-hole 13, and current pour sewerage 5 with the dirt in the sanitary equipment 4 through lower through-hole 13; As shown in Figure 5, when sewerage stopped up, float 2 floated in the last sewage that emits, and until being against on the upper valve base 15, the last through hole 12 that sealing is connected with sanitary equipment 4 emits the foul smell of sewage and dirt to escape through last through hole 12 in the prevention.
The utility model is applicable to and being connected and forming whole of lavatory, kitchen, bathroom, laundry sewerage.
