Abstract

The utility model relates to a double-valve sealing floor drainer consisting of a floor drainer main body, a floor drainer cover and one-way valves. The double-valve sealing floor drainer is characterized in that the floor drainer main body is internally provided with two one-way valves in sequence, and double-valve sealing is carried out to the floor drainer by using the one-way valves. The double-valve sealing floor drainer has the advantages of fast opening and closing, good sealing effect, little water flow resistance, strong self-cleaning capability and the like, and has good overflow-proof performance.

Description

A kind of bivalve seal floor drain

Technical field

The utility model relates to a kind of floor drain, especially a kind of bivalve seal floor drain.

Background technology

Existing floor drain mainly is divided into two kinds of water-seal floor drain and mechanical seal floor drains, and the existing ubiquitous problem of floor drain mainly shows: 1. the water seal height of most of water-seal floor drain is not enough, and majority has only 10-30mm, and is very easily dry; The sealing effectiveness of mechanical seal floor drain is relatively poor, often loses sealing function because of mechanical breakdown or foreign material; 2. the deep water feud drainability of leaking a little less than, be prone to the phenomenon of impeded drainage; 3. the self-purification ability of floor drain is poor, tangles hair, settled sludge easily, forms to stop up, and need often clear up.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, good sealing effect, water-flowing amount big, exempt to clear up, non-maintaining bivalve seal floor drain.

Bivalve seal floor drain of the present utility model mainly is made up of drain cover, floor drain body and one way valve.Drain cover is installed in the top of floor drain body, and one way valve is two, is installed in the inside or the bottom of floor drain body successively.The water inlet of one way valve matches with the water inlet of floor drain body, be generally circle, one way valve side direction center below water inlet is contracted to an end of outfall, the position of respective side below more also is contracted to the other end of outfall to the center, a valve is installed at the outfall place, one end of valve has rotating shaft, rotates by the rotating shaft fastening devices that is arranged on the check valve body, and valve utilizes the gravity of self that delivery port is sealed; The central axis of valve and one way valve has an angle α, and its angle is the 0-90 degree.The bottom of floor drain body is the pipe of long delivery port undergauge, and two one way valve series connection are packed in the pipe, and the delivery port undergauge of pipe helps forming siphon drainage, increases the drainability of floor drain.Short pipe also can be adopted in the bottom of floor drain body, and the valve of lower end one way valve is exposed to outside the pipe, can reduce the shared height of floor drain when being applied in the Homofloor drainage system.Two one way valves should be installed in opposite directions, and promptly its delivery port is beneficial to reduce the height of floor drain in the both sides of correspondence.

The beneficial effects of the utility model are, bivalve seal floor drain switch is rapid, resistance to water-flow is little, good sealing effect, self-cleaning ability are strong, simple in structure, easy to use.In addition, owing to have twice mechanical seal, so floor drain also has good overflow-proof performance.

Description of drawings

Accompanying drawing is the structural representation of bivalve seal floor drain.

Among the figure: 1. floor drain body, 2. drain cover, 3. one way valve, 4. one way valve.

The specific embodiment

With reference to the accompanying drawings, the bivalve seal floor drain is made up of floor drain body 1, drain cover 2, one way valve 3 and one way valve 4.Drain cover 2 is arranged at the top of floor drain body 1, and the lower end is the pipe of an outlet undergauge, and one way valve 3 and one way valve 4 are installed in the pipe of floor drain body 1 lower end successively.The course of work of bivalve seal floor drain is as follows: current enter in floor drain body 1 and the one way valve 3 by drain cover 2, and the valve of one way valve 3 and one way valve 4 is opened successively under the gravity of current and momentum effect, and the angle of big more its unlatching of current is also big more; Last current enter in the sewer by the undergauge delivery port of floor drain body 1 lower end pipe.After current stopped, one way valve 3 and one way valve 4 were closed thereupon; Rely on one way valve 3 and one way valve 4 formed twice mechanical seals, make floor drain be in sealing state completely.

Claims

1. a bivalve seal floor drain has floor drain body, drain cover and one way valve, it is characterized in that being equipped with successively in the floor drain body two one way valves.

2. a kind of bivalve seal floor drain according to claim 1, it is characterized in that described one way valve side direction center below water inlet is contracted to an end of outfall, the position of respective side below more also is contracted to the other end of outfall to the center, a valve is installed at the outfall place, one end of valve has rotating shaft, rotate by the rotating shaft fastening devices that is arranged on the check valve body, utilize the gravity of self that delivery port is sealed.

3. a kind of bivalve seal floor drain according to claim 1 is characterized in that the valve of described one way valve and the central axis of one way valve have an angle, and its angle is the 0-90 degree.

4. a kind of bivalve seal floor drain according to claim 1 is characterized in that described two one way valves are for installing in opposite directions.
