Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, in the embodiment of the present invention, a valve facilitating on-line conversion includes a pipeline 2 and a spare pipe 4, a main valve body 1 is installed in the middle of the pipeline 2, one end of the pipeline 2 is provided with a water inlet 21, and the other end of the pipeline 2 is provided with a water outlet 22, by opening the main valve body 1, water can enter from the water inlet 21, and water can flow out from the water outlet 22 after passing through the pipeline 2;

referring to fig. 1 and 2, the standby pipe 4 is located below the pipeline 2, two ends of the standby pipe 4 are communicated with the pipeline 2, a standby valve 5 is installed at one side of the standby pipe 4, and water can also reach the inside of the standby pipe 4 from the water inlet 21 by opening the standby valve 5;

referring to fig. 1, 2 and 3, when the main valve body 1 needs to be overhauled, by opening the standby valve 5 and detaching the main valve body, a delivery pipe 7 is installed above the other side of the standby pipe 4, a receiving hopper 6 is installed at the upper end of the delivery pipe 7, the receiving hopper 6 is located right below the main valve body 1, after water flows in from the water inlet 21, a part of the water flows into the inside of the pipeline 2, the other part of the water flows into the inside of the standby pipe 4, water can flow out from the detached position of the main valve body 1 after entering the inside of the pipeline 2, and after the water flows out, the water can reach the inside of the receiving hopper 6, then reaches the inside of the standby pipe 4 through the delivery pipe 77, and finally flows out from the position of the water outlet 22 after passing through the standby valve 5;

as shown in fig. 2 and 3, the middle part of the upper end of the delivery pipe 7 is provided with a check valve plate 10 for water flow to move from top to bottom, so that water in the spare pipe 4 can be prevented from entering the receiving hopper 6 upwards, and after the receiving hopper 6 receives water above, the check valve plate 10 can be pressed downwards due to the self weight of the water, so that the water flow enters the spare pipe 4;

as shown in fig. 1 and fig. 2, one end of the standby pipe 4 close to the water inlet 21 is fixedly connected with the tank body 3, the tank body 3 cuts off the pipeline 2, and the contact position between the two ends of the tank body 3 and the pipeline 2 is sealed, the tank body 3 is arranged to enlarge the end part of the standby pipe 4, so that when the standby valve 5 is opened, water can be stored in the tank body 3 and then directly enters the standby pipe 4, the amount of water directly flowing into the pipeline 2 is greatly reduced, the amount of water entering the receiving hopper 6 is greatly reduced, and the operation of the whole device is facilitated;

as shown in fig. 3, the lower end of the conveying pipe 7 extends out of the lower plate 8 towards the end, close to the water outlet 22, inside the spare pipe 4, the lower end of the lower plate 8 is provided with a reset hinge 9, the lower plate 8 is connected with the conveying pipe 7 through the reset hinge 9, the lower plate 8 can reserve the space above the inside of the spare pipe 4 below the conveying pipe 7, and therefore water entering from above can enter the inside of the spare pipe 4.

The working principle and the using process of the utility model are as follows: when the device is used, the water inlet 21 can be filled with water by opening the main valve body 1, and water can flow out from the water outlet 22 after passing through the pipeline 2;

when the main valve body 1 needs to be overhauled, the standby valve 5 is opened, the main valve body 1 is detached, water flow can reach the inside of the tank body 3 when entering water from the water inlet 21 and then move downwards until the water flow reaches the inside of the standby pipe 4, the water flow reaches one end, close to the water outlet 22, of the pipeline 2 through the standby valve 5, and water is discharged from the water outlet 22;

due to the arrangement of the tank body 3, only a small part of water can horizontally and directly reach the inside of the pipeline 2, then the water reaches the inside of the receiving hopper 6 from the position detached from the main valve body 1, the water reaches the inside of the conveying pipe 7 after the check valve plate 10 is pressed open, the water downwards reaches the inside of the standby pipe 4 along the lower plate 8, the check valve plate 10 can also prevent the water flow in the standby pipe 4 below from upwards reaching the inside of the receiving hopper 6, only the water above flows downwards, the lower plate 8 can reserve the space above the inside of the standby pipe 4 below the conveying pipe 7, and therefore the water flow entering from above can enter the inside of the standby pipe 4.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model.
