Abstract

Disclosed is a water channel anti-overflow valve, comprising a valve body and a valve core. An annular boss, with a pin seat arranged on the bottom surface, is arranged on the inner wall of the valve body. The valve core is articulated with the pin seat by pin. A torsion spring is arranged on the pin, with two ends resisted respectively to the bottom surface of the valve core and the inner wall of the valve. The upper surface of the valve core is faced with the bottom surface of the annular boss. Due to the utility model keeping in close status constantly, the odor diffusing can be prevented; the sewage is discharged when the valve is opened. When the sewer is jammed and the valve is resisted by the sewage, the valve can not be open and the sewage can not be discharged. The utility model is simple in structure, low in cost, convenient to install and is durable, which can be installed to any position without affecting the pipeline dredge.

Description

The sewer anti-overflow vave

Technical field

The utility model relates to the sewer annex.

Background technology

The sewer of each floor all communicates with main sewer in the building, sewage enters main sewer from the floor sewer and discharges, after main sewer stops up, the sewage of the floor discharging on obstruction place top will glow in the sewer of obstruction place top and the most approaching obstruction place floor, brings great trouble for the user of this floor.Also there is the general foul smell problem of sewer in addition.China Patent No. is that 00104297.1 utility model patent manual discloses the valve that a kind of anti-sewer pipe water refluxes, it is made up of valve body, valve ball, Zang Faqiugai and valve body suspension ring, in normal streamflow regime lower valve ball is ensconced the valve ball lid, when backflow phenomenon takes place, utilize the thrust of water to release valve ball from hiding in the valve ball lid, close the mouth of pipe and stop backflow, it plays containment sewer water and refluxes.

The utility model content

The purpose of this utility model is to propose a kind ofly can prevent the general sewage of sewer, can prevent the sewer anti-overflow vave of the general foul smell of sewer again.

For achieving the above object, the utility model takes valve interior wall to be provided with annular boss, the bottom surface of annular boss is provided with axis pin base, spool is hinged on the axis pin base by bearing pin, bearing pin is provided with torsion spring, on the inwall of bottom surface that reaches spool and valve body, the upper surface of spool pastes mutually with the bottom surface of annular boss respectively at the two ends of torsion spring.

Above-mentioned valve body is a tubulose, and spool is discoideus.

The upper surface of above-mentioned annular boss is the inclined plane.

Described two ends of valve body can be provided with internal thread or external screw thread.

The outer wall of described valve body is provided with tick lables.

Be provided with sealing ring between described annular boss and the spool.

The utility model is owing to be in normal closed condition, valve open during draining, sewage discharge.Stop up as sewer, valve is withstood by sewage, and valve is not opened, and sewage can't glow.Because valve is in normal closed condition, can prevent that foul smell glows; The utility model is simple in structure, cost is low, easy for installation, be easy to promote, be not easy to damage, and can install any position, do not influence pipe-dredging.

The specific embodiment

Fig. 1～shown in Figure 5, embodiment have valve body 1 and spool 2.Valve body 1 is a tubulose, and spool 2 is discoideus.The inwall of valve body 1 is provided with annular boss 1-1, and the upper surface of annular boss is the inclined plane, and the bottom surface is provided with pair of pin axle bed 1-2.For not influencing draining, annular boss 1-1 can be narrower, and one section 1-1-1 that axis pin base 1-2 is set on annular boss 1-1 so need widen and increase.Bearing pin 3 is connected on the axis pin base 1-2 by spool 2 its two ends, is with torsion spring 4 at the middle part of bearing pin 3, and the two ends of torsion spring 4 are respectively on the inwall of bottom surface that reaches spool 2 and valve body 1.The power that torsion spring 4 is produced is moderate, should guarantee that spool 2 often closes, and makes things convenient for draining again.Be being connected of convenient and sewer, the two ends of valve body 1 can be provided with internal thread or external screw thread.Be provided with sealing ring 5 between annular boss 1-1 and the spool 2, sealing ring 5 can be fixed on the annular boss 1-1, also can be fixed on the spool 2, and the outer wall of valve body 1 is provided with tick lables 5.

The utility model is in normal closed condition, and the upper surface of spool 2 pastes mutually with the bottom surface of annular boss 1-1, and during draining, under the gravity and impulse force of water, spool 2 is that central axis rotates with bearing pin 3, and anti-overflow vave is opened, and draining is smooth and easy.
