Disclosure of Invention

The utility model aims at overcoming prior art and can't in time learn whether the pipe network is in the shortcoming of going out the water state, provide a thermoplastic elastic material ball valve, can in time learn whether the pipe network is in the water state.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a ball valve made of thermoplastic elastic materials comprises a main body, a ball body rotationally connected in the main body and a handle used for rotating the ball body, wherein blades which automatically rotate when water passes through the ball body are arranged on the handle. When water is discharged, water can pass through the ball body, and the pipe network can be timely known to be in a water discharge state by observing the rotation of the blades.

Preferably, the handle is provided with a groove, the blade is positioned in the groove, and a notch of the groove is provided with a transparent mask. The mask protects the blades.

As preferred, the handle includes that pivot, rigid coupling of one end rigid coupling on the spheroid keep away from the commentaries on classics handle of spheroid one end in the pivot, the recess is located the pivot and keeps away from spheroidal one end, the pivot internal rotation is connected with rather than coaxial transfer line, transfer line one end with the blade rigid coupling, the transfer line other end is located the spheroid and the rigid coupling has the bevel gear, the rigid coupling has the support in the spheroid, it is connected with the second pivot to rotate on the support, second pivot one end rigid coupling has the second blade, second pivot other end rigid coupling has the second bevel gear with bevel gear meshing. The structure is simple.

Preferably, the ball and the rotating shaft are of an integrally formed structure. Is convenient for production.

Preferably, the transmission rod is fixedly connected with an upper limiting block and a lower limiting block which are used for preventing the transmission rod from moving axially, the upper limiting block abuts against the groove bottom of the groove, and the lower limiting block abuts against the inner side wall of the ball body. The structure is stable.

Preferably, the rotating handle is made of plastic. Is convenient for production.

Preferably, a plurality of weight reduction grooves are formed in the lower side of the rotating handle. The material is saved.

The utility model has the advantages that: the utility model provides a thermoplastic elastic material ball valve can in time learn whether the pipe network is in the water state.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is a cross-sectional view of the present invention.

In the figure: the weight-reducing mechanism comprises a main body 1, a ball 2, a handle 3, a groove 4, blades 5, a rotating shaft 6, a rotating handle 7, a mask 8, a transmission rod 9, a bevel gear 10, a support 11, a second rotating shaft 12, a second blade 13, a second bevel gear 14, an upper limiting block 15, a lower limiting block 16 and a weight-reducing groove 17.

Detailed Description

The invention will be further explained in detail with reference to the drawings and the following detailed description:

example (b):

referring to fig. 1 to 2, a ball valve of thermoplastic elastomer comprises a body 1, a ball 2 rotatably connected in the body 1, and a handle 3 for rotating the ball 2, wherein the handle 3 is provided with a blade 5 which automatically rotates when water passes through the ball 2. The handle 3 is provided with a groove 4, the blade 5 is positioned in the groove 4, and a notch of the groove 4 is provided with a transparent face mask 8.

The handle 3 comprises a rotating shaft 6 with one end fixedly connected on the sphere 2 and a rotating handle 7 fixedly connected on one end of the rotating shaft 6 far away from the sphere 2, wherein the rotating handle 7 is made of plastic material. A plurality of weight-reducing grooves 17 are arranged at the lower side of the rotating handle 7. Recess 4 is located the one end that spheroid 2 was kept away from to pivot 6, 6 internal rotations in the pivot are connected with rather than coaxial transfer line 9, transfer line 9 one end with blade 5 rigid coupling, the transfer line 9 other end is located spheroid 2 and the rigid coupling has bevel gear 10, the rigid coupling has support 11 in the spheroid 2, it is connected with second pivot 12 to rotate on the

support

11, 12 one end rigid couplings of second pivot have

second blade

13, 12 other end rigid couplings of second pivot have with bevel gear 10 engaged with second bevel gear 14. The ball body 2 and the rotating shaft 6 are of an integrally formed structure. An upper limiting block 15 and a lower limiting block 16 for preventing the transmission rod 9 from moving axially are fixedly connected to the transmission rod 9, the upper limiting block 15 abuts against the bottom of the groove 4, and the lower limiting block 16 abuts against the inner side wall of the ball body 2.

Principle of embodiment:

after the handle 3 is rotated, when a water faucet is opened or a large amount of water is discharged due to the damage of a pipeline, the water can penetrate through the sphere 2, the water drives the second blade 13 to rotate, the second bevel gear 14 rotates, the bevel gear 10 rotates, the transmission rod 9 rotates, the blade 5 rotates, and the situation that the pipe network is in a water discharge state can be known by observing the blade 5.

When the handle 3 is rotated reversely, the ball valve is closed, water cannot pass through the ball body 2, and the blades 5 stop rotating.
