Abstract

A double-seal floor drain comprises a floor drain main body, a floor drain cover, a one-way valve and a drain trap, wherein, the one-way valve and the drain trap are mounted in the interior or at the lower part of floor drain main body in sequence; and double seal for floor drain can be achieved by utilizing the mechanical seal of the one-way valve and the water seal of the drain trap. The double-seal floor drain has the advantages of fast switch on and off, good sealing effect, small water flow resistance, high self-cleaning capability, excellent anti-return and anti-overflow performance, and the like.

Description

A kind of double sealing floor drain

Technical field

The utility model relates to a kind of floor drain, especially a kind of double sealing 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 floor drain kind that has water seal and mechanical seal simultaneously seldom.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 is to provide a kind of simple in structure, good sealing effect, big, strong, the non-maintaining double sealing floor drain of self-cleaning ability of water-flowing amount.

Double sealing floor drain of the present utility model mainly is made up of drain cover, floor drain body, one way valve and trap.Drain cover is installed in the top of floor drain body, and one way valve and trap are installed in the inside or the bottom of floor drain body.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 one way valve, 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 water inlet of trap also is circular, and to opposite side, the bottom that makes trap is a hemispherical to the side below water inlet by arc transition; The opposite side of water inlet below is shrunk to a plane to the center and inserts in the hemisphere, thereby forms water seal; The water seal height of trap is 0-50mm, is advisable with 5mm.The bottom of floor drain body is the pipe of long delivery port undergauge, and trap and one way valve are packed in the pipe successively, and the delivery port undergauge of pipe helps forming siphon drainage, increases the drainability of floor drain.The bottom of floor drain body also can be adopted short pipe or do not had pipe, one way valve can be directly installed on the trap inner upper end of increasing, again trap is installed on the floor drain body, can reduces the shared height of floor drain when being applied in the Homofloor drainage system.One way valve and trap 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, not only can reduce cost, and help application in Homofloor drainage system.

The beneficial effects of the utility model are, the double sealing floor drain switch is rapid, resistance to water-flow is little, good sealing effect, strong, simple in structure, the convenient maintenance of self-cleaning ability.Because the water seal of trap is subjected to the protection of one way valve mechanical seal, so be difficult for drying up, can keeping sealing function for a long time; Water in the trap water seal simultaneously because of long corrupt fouling of time after because the existence of one way valve, the foul smell of generation and stink can inlet chamber yet in but enter in the sewer, so have fabulous deodorant function.Because the water seal height of trap can reduce greatly, so resistance to water-flow also can reduce and have good self-cleaning ability greatly.In addition, owing to have mechanical seal, so double sealing floor drain also has good overflow-proof performance.

Description of drawings

Accompanying drawing is the structural representation of double sealing floor drain.

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

The specific embodiment

With reference to the accompanying drawings, double sealing floor drain is made up of floor drain body 1, drain cover 2, one way valve 3 and trap 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 trap 4 are installed in the pipe successively.The course of work of double sealing floor drain is as follows: current enter in floor drain body 1 and the one way valve 3 by drain cover 2, the valve open of one way valve 3 under the gravity of current and momentum effect, and the angle of big more its unlatching of current is also big more; Current accumulate in the trap 4 after by one way valve 3, and current enter in the sewer by the undergauge delivery port of floor drain body 1 lower end pipe after the water seal of trap 4 is full of.After current stopped, one way valve 3 was closed thereupon, and the water in trap 4 water seals no longer flows out, and formed water seal; If long-time anhydrous the entering of floor drain, the water seal of the mechanical seal of one way valve 3 and trap 4 still exists, and floor drain still is in sealing state completely.

Claims

1. a double sealing floor drain has floor drain body and drain cover, it is characterized in that the inside of floor drain body or bottom be equipped with an one way valve and a trap successively.

2. a kind of double sealing 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 one way valve, valve utilizes the gravity of self that delivery port is sealed.

3. a kind of double sealing 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 double sealing floor drain according to claim 1 is characterized in that the side of described trap below water inlet arrives opposite side by arc transition, and the bottom that makes trap is a hemispherical; The opposite side of water inlet below is shrunk to a plane to the center and inserts in the hemisphere, forms water seal.

5. a kind of double sealing floor drain according to claim 1 is characterized in that described one way valve can be installed in the trap.
