Description

Pipeline Liquid Leak Detection Device

The invention relates to a pipeline liquid leakage detection device, which is a functional component of hydroelectric equipment.

The applicant has previously applied for the patent case of Certificate No. M566735 "Water Tank Leak Detection Device", in which there is a rotating member pivotally arranged in a connecting member, so after the device is connected between the water source and the toilet tank, if the water tank leaks water , the rotary member will continue to rotate, which can remind personnel to deal with the water leakage;

However, after actual use, it is found that because the rotating part itself still has a certain weight, and there is friction between the rotating part and the shaft center, the rotation of the rotating part will be slower and less obvious when water leaks, even when a small amount of water leaks. The rotating part may not rotate, and the reminder effect cannot be effectively played.

In view of the above shortcomings, the inventor believes that it is necessary to make corrections, so with years of experience in related technologies and product design and manufacturing, adhering to good design concepts, research and creation for the above shortcomings, after continuous efforts, finally The pipeline liquid leakage detection device of the present invention is introduced, in order to correct the product structure and improve the excellent effect of the product.

The main purpose of the pipeline liquid leak detection device of the present invention is to provide a leak detection device structure with a relatively sensitive rotating member.

In order to achieve the purpose disclosed above, the pipeline liquid leakage detection device of the present invention includes:

A flow seat has a seat body, one side of the seat body is concave with a seat chamber, a shaft column is formed protruding from the center of the seat chamber, the shaft column has a tip, and the outer side of the seat body is extended to form two connecting parts. The connecting part runs through a channel which communicates with the seat chamber, and the two channels are staggered from the shaft column. The seat body is further recessed with a ring groove surrounding the seat chamber, and a leak-proof ring is installed in the ring groove;

A rotary member located in the seat chamber has a base, a plurality of blades are formed on the outside of the base, and one end of the base is concavely provided with a shaft chamber and an air chamber, and the air chamber surrounds the shaft chamber;

a closed ring installed in the air chamber;

a shaft sleeve, which has a sleeve body with an annular cross-section, the sleeve body defines a set of chambers, the shaft sleeve is installed in the shaft chamber, and the shaft sleeve is also sleeved on the shaft column with the sleeve chamber;

A cover plate is fixed on the seat body and abuts against the leak-proof ring, so that the cover plate covers the seat chamber.

The circulation seat is used to install in the liquid pipeline between the toilet tank and the water source, so when the toilet is flushed, the water can flow into the water tank from the water source through the circulation seat, and the rotating part will be pushed by the water flow to rotate;

And if the water tank leaks, the water will continue to flow from the water source through the flow seat, so that the rotating part keeps rotating, so the personnel can know whether there is water leakage and needs to be repaired by observing the rotating part.

Compared with the previous "water tank leak detection device", the rotating part of this device has an air chamber, which can reduce the weight and reduce the friction between the shaft sleeve and the shaft column, thereby making the rotating part easier to be damaged. The water flow has high sensitivity, so even if there is only a small amount of water leakage in the water tank, the rotary member will still rotate accordingly to achieve the prompting effect. It can be seen that the present invention is a progressive creation.

[Please refer to the first to fourth figures] The present invention relates to a pipeline liquid leakage detection device, which includes:

A circulation seat (1) has a seat body (11), one side of the seat body (11) is concavely provided with a circular groove-shaped seat chamber (12), the center of the seat chamber (12) protrudes to form a shaft column (13) ), the shaft column (13) has a tip (131), and two connecting parts (14) are formed on the outside of the seat body (11), and the ends of the two connecting parts (14) are set to face opposite directions, and the two connecting parts (14) are arranged to face opposite directions. The connecting parts (14) are set to be staggered and not corresponding, and both the connecting parts (14) pass through a channel (15) that communicates with the seat chamber (12). (15) are all staggered from the shaft column (13), the seat body (11) is also recessed with a ring groove (16) surrounding the seat chamber (12), and the ring groove (16) is provided with a leak-proof ring ( 17);

A rotating member (2) located in the seat chamber (12), has a base (21), a plurality of blades (22) are formed on the outside of the base (21), and a circle is concave at one end of the base (21). The groove-shaped shaft chamber (23) and an air chamber (24), and the air chamber (24) surrounds the shaft chamber (23), and the other end of the base (21) runs through a connection to the shaft chamber (23). A shaft hole (25), the diameter of the shaft hole (25) is smaller than that of the shaft chamber (23);

a closed ring (3), installed in the air chamber (24), the thickness of the closed ring (3) is smaller than the depth of the air chamber (24);

A shaft sleeve (4) has a sleeve body (41) with an annular cross section, the sleeve body (41) defines a set of chambers (42), and one end of the sleeve body (41) penetrates through a sleeve connected to the sleeve body (41). The sleeve hole (43) of the sleeve chamber (42), the diameter of the sleeve hole (43) is smaller than the sleeve chamber (42), and the shaft sleeve (4) has the sleeve hole (43) facing the shaft chamber (23). The state is installed in the shaft chamber (23), and the shaft sleeve (4) is also sleeved on the shaft column (13) by the sleeve chamber (42);

A pair of shaft members (5) have a pair of shaft bodies (51), one end of the pair of shaft bodies (51) is concavely provided with a conical groove (52), and the pair of shaft members (5) is formed by the groove (52). ) is installed in the sleeve hole (43) in the state facing the sleeve chamber (42), so that the groove (52) corresponds to the tip (131) of the shaft column (13);

a cover plate (6), fixed on the seat body (11) and abutted against the leak-proof ring (17), so that the cover plate (6) covers the seat chamber (12);

A deceleration member (7) is installed in one of the passages (15).

[Refer to Figures 1 to 4] This device is used to install in a liquid pipeline to detect whether there is liquid leakage. Here, the device is installed in a toilet pipeline as an example. In this case, the connection part (14) with the speed reduction element (7) is connected to the water source by a water source water pipe, and the other connection part (14) is connected to the toilet tank by a water tank water pipe;

[Please also refer to the fifth picture] Therefore, when the water tank is flushed, the water can flow from the water source water pipe into the seat chamber (12) through the channel (15), and then flow into the water tank from the water tank water pipe through another channel (15) until When the water tank reaches the stop water level, the rotating member (2) is rotated by the impact of the water flow during the process, and the speed reduction member (7) can slow down the water flow speed to prevent the rotating member (2) from rotating too fast and making too much noise;

If there is water leakage in the water tank, the water will continue to flow into the seat chamber (12) and make the rotary member (2) rotate all the time. Therefore, if a person sees that the rotary member (2) is still rotating after flushing for a period of time, it means that the rotary member (2) is still rotating. It can be known that the water tank is leaking and needs to be repaired.

[Refer to Figures 1 to 5] One of the features of this device is the air chamber (24) of the rotary member (2). The air chamber (24) can reduce the weight of the rotary member (2), so even if the water tank is only A small amount of water leaks, so that the water flow into the seat chamber (12) is small when the water leaks, and the rotating member (2) can still be pushed to play a prompting effect, which means that it is similar to the rotating member (2) without the air chamber (24). Compared with that, the rotary member (2) with the air chamber (24) has higher detection sensitivity, so as to effectively remind the personnel to deal with the water leakage;

In addition, after the weight of the rotary member (2) is reduced by the air chamber (24), the frictional force when the shaft sleeve (4) abuts against the shaft column (13) is also reduced, and the rotary member (2) is also reduced. It is easier to rotate when pushed.
