Specific implementation mode

A kind of sewer U-tube with clearing function, be by U-tube 1, sewer pipe 2, drainage tube 3, check valve 1, What cylinder barrel 5, piston 6, handle 7, transverse tube 8 and check valve 29 formed, 1 bottom sides of U-tube have passed through transverse tube 8, and transverse tube 8 is equipped with single To valve 1, it is connected with cylinder barrel 5, piston 6 is equipped in cylinder barrel 5, has handle 7,5 lower part of cylinder barrel to pass through drainage tube 3, drainage tube on piston 6 3 are internally provided with check valve 29, and 3 rear portion of drainage tube is connected with sewer mouth 2, and 3 rear portion of drainage tube tilts down installation.

The check valve 1 is identical with 29 structure of check valve.

When being normal pressure in the cylinder barrel 5, check valve 1 and check valve 29 are in off state；In the cylinder barrel 5 For negative pressure when, check valve 1 open and check valve 29 close；When being high pressure in the cylinder barrel 5, check valve 1 is closed and list It is opened to valve 29.

The check valve 4 is made of valve wall 41, valve body 42, blocking ball 43, spring 44 and spring support 45, entire unidirectional 4 cylinder structure of valve, valve wall 41 are the shell of entire check valve 4, and valve body 42 and spring support 45 are located in valve wall 41 The both ends in portion have hole, the both ends of valve body 42 to have bellmouth, the inside of the spring support 45 to be connected with bullet among the valve body 42 One end of spring 44, spring 44 is connected on spring support 45, and the other end, which is connected with, blocks ball 43, in the elastic reaction of spring 44 Under, it blocks ball 43 and the bellmouth of 42 inside of valve body fits, the spring support 45 is the intermediate cross for carrying a disk Type structure.

The invention is when not used, and the position of each component is as shown in figure 4, particularly note that the installation of check valve 4 and check valve 9 Mode.

Since the inlet of common u-shaped pipe is slipped through the net, thus enters U-tube under normal conditions and form the dirt sunk to the bottom Small, essentially particle or micro- flour are easy to form purees.

When there is dirt, dirt is full of the bottom of U-tube, as shown in Figure 4.Handle 7 is pulled at this time, makes piston 6 into Fig. 5 Left side movement, at this point, generating negative pressure in the cylinder barrel 5, which moves up the blocking ball 43 for making check valve 9, to stifled The firmly hole in the valve body of check valve 9 makes check valve 9 turn off.Meanwhile the negative pressure in cylinder barrel 5 makes the blocking ball 43 of check valve 4 overcome The elasticity of spring 44 makes blocking ball 43 leave the hole wall of the bellmouth of valve body 42, to make the dirt of U-tube bottom pass through unidirectionally The hole of the valve body 42 of valve 4 enters in the space of cylinder barrel 5.

When handle 7 is drawn to its stop, as shown in figure 5, will there are many dirts to enter cylinder barrel 5 together with water at this time Space in, driving handle 7 inwardly moves again at this time, and to generate high pressure in the cylinder barrel 5, this high pressure will make the stifled of check valve 9 Plug ball 43 overcomes the elasticity of its spring 44 to move down, and to make blocking ball 43 leave the bellmouth of valve body 42, makes 9 shape of check valve At access；And check valve 4 due in cylinder barrel 5 negative pressure disappear, block ball 43 by under the promotion of spring 44, again with valve body 42 Taper hole wall is bonded, and forms the closing of check valve 4；Even if blocking at this time between ball 43 and valve body 42 still has dirt, make blocking ball 43 are difficult to be bonded with the taper hole wall of valve body 42 completely, have no effect on the closing of check valve 4；In this case, with handle 7 With the movement of piston 6, the dirt in cylinder barrel 5 can be entered by the hole of check valve 9 in drainage tube 3；The drainage tube 3 is Inclined structure, the dirt internal into it can be with flow under gravity, into sewer pipe, the above process Termination figure it is as shown in Figure 6.

Repeat that above-mentioned movement is multiple in cleaning device, until most dirts in U-tube are cleaned.When clear When managing clean, handle 7 is pushed back into inner dead point, the blocking ball 43 of check valve 9 fits to the cone of valve body 42 under the thrust of spring 44 On shape hole wall, to make check valve 9 turn off, the taste overflow in sewer is avoided.Check valve 4 similarly turns off.And at this time It discharges water in U-tube, water will not flow out, and both form the closure of U-tube, equally avoid the taste overflow in sewer 2.

For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with In the case of spirit, changes, modifications, replacement and modification that embodiment is carried out still fall within protection scope of the present invention it It is interior.
