Abstract

The utility model discloses a trap. The middle part of the water inlet section of the trap pipe fitting is provided with a float valve chamber; a float ball of which the diameter is bigger than the inner diameters of an inlet and an outlet of the trap is arranged in the float valve chamber; the pipe fitting and the float ball are made of plastics or metallic materials; the structure of the pipe fitting can be made into a U shape, an S shape and a P shape. The utility model has the advantages of strong anti-stench capability, less water consumption, simple structure, easy production and convenient operation, and is suitable for various kinds of sewage pipeline engineering.

Description

The two pent-up waters of ball float are curved

Technical field

The utility model relates to a kind of construction drainage pipe fitting, and more particularly, the utility model relates to a kind of trap with deodorization, water saving effect.

Background technology

At present, produce on the market and the trap that uses is to seal with its water that is stored in the bend pipe, its major defect is: bent portion stops up easily, parts are lost easily, for example the bell-jar trap both stopped up easily, and bell jar is dismantled easily again and lost, and loses the water seal effect; Water seal was lost efficacy easily, or the siphonage during because of draining crosses strong water deficiency, or because of the water of being deposited is evaporated, caused the direct upper punch of foul smell, lost the effect of sealing deodorization; Water content consumption is big, the running cost height.

Summary of the invention

The purpose of this utility model provides a kind of good sealing effect, and water content consumption is few, the trap that running cost is low.The utility model is achieved through the following technical solutions.Trap pipe fitting of the present utility model comprises inlet segment, bend loss, water exit end, it is characterized in that, the middle part of described inlet segment is provided with the float valve chamber of an inner wall smooth, and a ganoid movable ball float is housed in the float valve chamber, and the external diameter of ball float is greater than the import and export internal diameter of this trap.Described ball float both can be put into earlier in this float valve chamber of manufacturing and trap pipe fitting current events, can't take out after making, can only be with described trap integral replacing when needing to change; Also can the manhole of an internal diameter greater than the ball float external diameter be set in this float valve chamber side, and add dismountable manhole cover, ball float can be put into easily and take out by manhole.The utility model can manufacture the U type, S type, P type.Described ball float hollow plastics ball also can be used the hollow metal ball.Described trap pipe fitting and the float valve chamber of one is made of plastic with it also can be made with metal.

Below operating principle of the present utility model is described.When ball float was in the bottom of float valve chamber, if anhydrous or water shortage does not form water seal in the bend loss, ball float can be blocked passing through of foul smell; If water is arranged in the bend loss and can form water seal, ball float can prevent evaporation of water; If ball float drops to here with effluent discharge, can offset then that sewage flows downward and the siphonage that produces, after this sewage begins to reflux.When ball float rose with sewage backflow and arrives the top of float valve chamber, ball float stoped sewage further to rise, and can prevent that water below the ball float is evaporated the rising with foul smell.When the needs sewage effluent, under the effect of sewage pressure in the ball float upper pipe, ball float is opened automatically and is carried out blowdown.The 1.5-2 that the internal diameter span of float valve chamber is controlled at described trap nominal diameter doubly is advisable, and the 2-2.2 that the height span of float valve chamber is controlled at the curved nominal diameter of described water doubly is advisable, if the too small drainage flow that then influences, if the excessive waste that then causes water.The external diameter value of ball float be this trap wall thickness 2-3 doubly with this trap internal diameter sum, unsuitable too small or excessive.The utility model is applicable to various sewer pipe engineerings.

The utility model compared with prior art has following advantage:

The sealing time long, the deodorization ability is strong;

2. water content consumption is few, and running cost is low;

3, simple in structure, easy to use.

Description of drawings

Fig. 1 is the vertical section structure schematic diagram of first kind of embodiment of the utility model;

Fig. 2 is the vertical section structure schematic diagram of second kind of embodiment of present embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples

In Fig. 1, trap pipe fitting 1 is engineering plastics with ball float 2 and makes, trap pipe fitting 1 and with it the float valve chamber 3 of one make so that injection molding way is whole, ball float 2 is put in advance in the process of its manufacturing.

In Fig. 2, trap pipe fitting 1 whole the manufacturing, its middle part is provided with float valve chamber 3, and the float valve chamber side is provided with manhole, and manhole cover sealing ring 4 and manhole cover 5 are arranged, and the internal diameter of manhole is greater than the external diameter of ball float 2, and ball float 2 is put into and is taken out by manhole.Pipe fitting 1 and port lid 5 are cylinder iron made, also can be made of plastic.

Claims

1, the two pent-up waters of ball float are curved, it comprises inlet segment, bend loss and water exit end, it is characterized in that: the inlet segment middle part of described trap is provided with the float valve chamber of an inner wall smooth, indoor be equipped with one can be movable ganoid ball float, the external diameter of ball float is greater than the import and export bore of trap, and the weight of ball float is less than its suffered overcurrent buoyancy of liquid.

2, trap according to claim 1, it is characterized in that: the top of described float valve chamber is coniform and links to each other with inlet segment, the middle part is cylindric, and the bottom is to stand upside down and coniformly links to each other with bend loss, inlet segment, float valve chamber, bend loss, water exit end is connected in turn make an integral body.

3, trap according to claim 1 is characterized in that: described float valve chamber sidewall has a circular hole, and the internal diameter of circular hole is greater than the external diameter of ball float, and circular hole is with end socket or blind plate and encapsulant sealing.
