Abstract
The utility model relates to a multifunctional check valve for sewages, which comprises a connection pipe and a valve body. The utility model has an essential technical proposal that the valve body is composed of a three-way pipe, an upper elbow, a lower elbow and a discharge pipe, wherein, the upper part of a straight pipe on the three-way pipe encapsulates a floating ball by using the connection pipe, and the lower part of the straight pipe is provided with a spacing block for the floating ball. The utility model has the advantages of reasonable structural design, easy use sanitation, and reliable seal, can effectively prevent polluted water from flowing back when a sewage is blocked, can prevent insects, such as roaches, etc. from creeping along a sewer line, and can prevent abnormal flavour from overflowing.
Description
Technical field
The utility model relates to a kind of non retern valve, the multi-functional non retern valve of particularly a kind of sewer.
Background technology
At present, sewer adopts the hydrolock structure mostly with blowoff valve, promptly with the non retern valve of being with water seal, the employing straight non retern valve that also has.Sewage takes place and flows backwards when sewer is obstructed in these non retern valves easily, and environment is polluted.In addition, existing non retern valve can not stop some insects such as cockroach to creep along sewer pipe, can't prevent that also peculiar smell from overflowing.
The utility model content
The purpose of this utility model provides the multi-functional non retern valve of a kind of sewer, its reasonable in design, and easy to use, health, sealing is reliable.Can not only prevent effectively when sewer is obstructed that sewage from flowing backwards, and can stop some insects such as cockroach to creep, prevent that along sewer pipe peculiar smell from overflowing.
The purpose of this utility model is achieved in that this device comprises tube connector and valve body, its technical essential is: valve body is made of tee piece, upper and lower elbow and delivery pipe, the riser upper portions of tee piece is utilized tube connector encapsulation ball float, and the vertical tube bottom is provided with the limiting block of ball float.
Above-mentioned tube connector joins by the vertical tube of screw thread and tee piece, and the tube connector end is the arc surface that matches with sphere with the contact surface of ball float.
Because the utility model adopts the float-ball type hermetically-sealed construction is set in tee piece, thus reasonable in design, handling ease, easy to use, health.Utilization remains in the pressure of the water in the pipe, guarantees ball float and the contact that is connected the mouth of pipe, and sealing is reliable.Because of this good seal performance, flow backwards so can not only when sewer is obstructed, effectively prevent sewage, and can stop some insects such as cockroach to creep, prevent that along sewer pipe peculiar smell from overflowing.Therefore, the utility model is applied easily.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of I type structural representation of the present utility model.
Fig. 2 is a kind of II type structural representation of the present utility model.
Specific implementation method
Describe the concrete structure of the present utility model and the course of work in detail according to Fig. 1-2.This device can be made I type structure (as shown in Figure 1) and II type structure (as shown in Figure 2) according to actual instructions for use.It can adopt metal material (as cast iron etc.) or nonmetals (as plastics etc.) to make.This valve comprises tube connector 1, valve body and assembles its interior ball float 2.Wherein valve body is made of tee piece 3, last elbow 7, following elbow 5 and delivery pipe 6 etc.The riser upper portions of tee piece 3 is utilized tube connector 1 encapsulation ball float 2, and tube connector 1 joins by the vertical tube of screw thread and tee piece 3, and tube connector 1 end is the arc surface that matches with sphere with the contact surface of ball float 2.For preventing that ball float 2 from washing away from following elbow, is provided with the limiting block 4 of ball float 2 in the vertical tube bottom of tee piece 3.The position of ball float 2 in pipe can be controlled by regulating the length that tube connector 1 stretches into tee piece, guarantees the sealing function power of 2 pairs of tube connector 1 ends of ball float.
During use, when sewage enters from tube connector 1, ball float 2 is depressed, water enters delivery pipe 6 from the transverse passage-way of tee piece 3, last elbow 7 and discharges health, convenience.When stopping sewage effluent, ball float 2 is subjected to remaining in down water in elbow 6 and the tee piece 3 to the buoyancy of ball float 2, be close on the arc surface of tube connector 1 end, reached and to have prevented effectively when sewer is obstructed that sewage from flowing backwards, and can stop some insects such as cockroach to creep, prevent the purpose of the sealing that peculiar smell overflows along sewer pipe.
Claims (2)
