Abstract

The utility model relates to a novel drainage device, which is suitable for the drainage of sanitary ware of households, hotels, public washrooms, etc. The utility model is characterized in that an external screw thread sleeve pipe, an internal screw thread sleeve pipe, an 'S'-shaped bent pipe and a through pipe are mutually connected by screw threads; interfaces are sealed by a large sealing gasket, an 'O'-shaped sealing ring and a small sealing gasket, and a hollow float ball is arranged in the internal screw thread sleeve pipe; the hollow float ball floats between the lower part of an annular sealing ring on a conical surface step in the internal screw thread sleeve pipe and the end surface of a conical hole in the 'S'-shaped bent pipe; accordingly, the utility model realizes the functions of closed stench upward flow, sewage reverse overflow and normal drainage.

Description

Novel dewatering installation

The utility model belongs to daily life sanitary appliance dewatering installation, with supporting uses of sanitaryware such as family, hotel, communal bathrooms.

Existing various sanitaryware such as wash one's face, wash the dishes, be to adopt under sanitary equipment, to connect " S " type bend pipe and carry out sewage effluent, repair difficulty in case stop up, and sewer pipe stops up the back foul smell, sewage will return into indoor inevitably, particularly Yan Re summer or arid area, the water capacity of pipe bent position easily evaporation are dry, lose the water seal effect, and interface also often leaks or drips, and influences environment for use.

The purpose of this utility model is exactly the easy obstruction that exists at existing sanitary equipment dewatering installation, the reliably anti-foul smell of nothing, and bilge water resisting returns excessive device, and the problem of maintenance difficult, and a kind of installation of proposition is simple, uses reliably novel dewatering installation easy to maintenance.

The utility model is mainly formed by opening and closing Dual purpose plug, internal and external screw thread sleeve pipe, hollow float, " S " type bend pipe, straight pipe and various seal.It is step-like that one end of external thread sleeve is inner cone, cooperates in sanitaryware outward, interiorly cooperatively interacts in opening and closing Dual purpose plug, reliable for making sealing, cooperate closely, and outside below the frustum rank, tapered sealing mat of suit, and the other end connects in the internal thread sleeve pipe.Opening and closing the Dual purpose plug external diameter goes to upper and lower coniform, the lower end male cone (strobilus masculinus) has some radially grooves, the upper and lower conical surface all can cooperate with the external thread sleeve inner conical surface, if with following cone match, sewage can filter through groove and enter in the pipe, normal draining, if with last cone match, can cut stifled clean water and enter in the pipe, this moment, water can wash.Internal thread sleeve pipe two ends have and external thread sleeve, the screw thread that " S " type bend pipe is connected, and there is the upper and lower step that is inner conical surface the centre, is with ring-like sealing ring on it.Internal thread sleeve pipe and external thread sleeve junction seal with " O " RunddichtringO with " S " type bend pipe junction with a big sealing mat sealing.The end face that " S " type bend pipe is connected with the internal thread sleeve pipe is the inner conical surface closed, its center has the hole of matching with hollow float, the other end also has screw thread and is connected with a straight pipe, and adopts a little sealing mat sealing, and the lower end of straight pipe cooperates with the ground fistulae.Hollow float places within the internal thread sleeve pipe, is having under the ring-like sealing ring of inner conical surface step, and is having upper and lower floating between the end face of " S " type bend pipe of inner conical surface closed.During not draining, ball float is seated in by deadweight on the end face taper hole of " S " type bend pipe, and the sealing taper hole prevents to return on the foul smell.When sewage or tap water enter in the internal thread sleeve pipe by opening and closing the Dual purpose plug groove, by buoyancy hollow float is floated, sewage or tap water just enter sewer pipe by the taper hole on " S " type bend pipe, lean on gravity to seal taper hole automatically after current finish again.After sewer pipe stopped up, pressure made sewage pass through " S " type bend pipe and enters, and hollow float is floated, along with buoyancy increases, hollow float can be blocked the stepped hole that has ring-like sealing ring in the internal thread sleeve pipe again, make sewage can not inlet chamber in, pressure is big more, seals tight more.Therefore, external thread sleeve, internal thread sleeve pipe, " S " type bend pipe, straight pipe are connected with each other, between interface, add the sealing ring sealing respectively, so just formed a new dewatering installation.

The utility model is compared with existing gutter, has anti-foul smell, bilge water resisting is excessive in indoor function, returns on the anti-foul smell, bilge water resisting is excessive reliable, and installation and maintenance are convenient, are a kind of novel dewatering installations.

Below with reference to accompanying drawing the utility model is further described.

Accompanying drawing is the utility model structural representation.

Among the figure, 1 for opening and closing Dual purpose plug, and 2 is tapered sealing mat, and 3 is external thread sleeve, and 4 is big sealing mat, and 5 is the internal thread sleeve pipe, and 6 is ring-like sealing ring, and 7 is hollow float, and 8 is " O " RunddichtringO, and 9 is " S " type bend pipe, and 10 is little sealing mat, and 11 is straight pipe.

Among the figure, the external thread sleeve 3 that is with tapered sealing mat 2 is inserted in the through hole that discharges water of sanitaryware bottom surface, the lower end puts big sealing mat 4, with the centre be with ring-like sealing ring 6 internal thread sleeve pipe 5 screw in external thread sleeves 3 lower ends and tighten, " O " RunddichtringO 8 is packed into " S " type bend pipe 9 upper external screw thread sleeve pipes 3 roots, after in the taper hole of upper surface, placing hollow float 7, screwing in internal thread sleeve pipe 3 lower ends tightens, earlier ground leak or sewer pipe are inserted in straight pipe 11 lower ends, place little sealing mat 10 the internal thread bottom, upper end of straight pipe 11 to be tightened against " S " type bend pipe lower end again, at last with mortar with straight pipe 11 lower end closed, so just formed a new dewatering installation.

When draining, some radially grooves enter external thread sleeve 3 after filtering to sewage after the use on the Dual purpose plug 1 lower end male cone (strobilus masculinus) through opening and closing, and enter in the internal thread sleeve pipe 5 through ring-like close circle 6 centers, the hollow float 7 that will be seated in " S " type bend pipe 9 tops by buoyancy automatically floats, the trap that hole by the top enters " S " type bend pipe 9 flows into straight pipe 11 until sewer pipe, thereby realizes draining.Draining is interrupted, and hollow float 7 rolls into from gravity on the center taper hole at " S " type bend pipe 9 tops automatically by it, realizes scurrying on the dual sealing foul smell with the water seal of " S " type bend pipe 9, is in the deodorization state.In case main sewer pipe stops up, sewage backflows from bottom to top, can float hollow float 7, makes it rise to 6 times stomidiums of ring-like sealing ring, and shuts through hole, has sealed the passage that sewage makes progress, and prevents that sewage from overflowing in indoor, thereby has realized the excessive function of bilge water resisting.This dewatering installation, can deodorization, anti-blocking, bilge water resisting is excessive, can carry out normal sewer simultaneously, is a kind of suitable novel dewatering installation.

When needing things such as water washing clothes in addition when sanitary equipment, spin upside down use as long as will open and close Dual purpose plug 1.
