Detailed Description
The present utility model will be described in detail below with reference to the drawings and examples. The following examples are illustrative of the present utility model and should not be construed as limiting the utility model to the following examples.
Referring to the drawings, in this embodiment, a water hammer protection device in a water supply system includes a water supply pipe 1, a pressure relief straight pipe assembly 2, and a valve body assembly 3. The pressure relief straight pipe component 2 is vertically arranged on the water supply pipe 1 and is communicated with the water supply pipe 1, the internal pressure of the pressure relief straight pipe component 2 is reduced when a water hammer acts on the water supply pipe 1, the valve body component 3 is in a closed state when the water hammer acts on the water supply pipe 1 in a normal state, and the valve body component 3 is positioned at the water inlet end of a switch for controlling the opening or closing of the water supply pipe 1.
Specifically, the water supply pipe 1 supplies water normally, when the switch is closed, the water hammer effect appears in the water supply pipe 1, and part of water strikes on the valve body subassembly 3 this moment for the valve body subassembly 3 is closed, and in surplus water then gushed into pressure release straight tube subassembly 2, carries out the pressure release through the mode of rising the water level, reduces the impact that the water striking caused water supply pipe 1 inner wall. And when the water hammer effect disappears, the water level in the pressure release straight pipe component 2 is lowered and reset. By properly releasing the pressure, the force of the water impact is prevented from directly acting on the wall of the water supply pipe 1, so that the risk of closing and damaging the water supply pipe 1 is reduced.
For the purpose of understanding the technical solution of the present utility model, a further explanation of the pressure relief straight tube assembly 2 will be provided.
The pressure relief straight tube assembly 2 includes: a tube 21, a piston 22 and a drive motor 23.
The piston 22 is located in the pipe body 21 and is in transmission connection with a driving motor 23 fixed on the top of the pipe body 21, so as to realize up-and-down movement of the piston 22 in the pipe body 21, and the bottom end of the pipe body 21 is communicated with the water supply pipe 1.
Specifically, the size of the cavity in the portion where the pipe body 21 communicates with the water supply pipe 1 is adjusted by the up-and-down movement of the piston 22. When the water supply pipe 1 supplies water normally, the piston 22 is positioned at the lower part of the inner side of the pipe body 21, and when the water supply pipe 1 is closed, the piston 22 rises under the action of the driving motor 23 to increase the cavity volume of the communicating part of the pipe body 21 and the water supply pipe 1, so that a storage space is provided for the water which is flushed in, and the aim of pressure relief is fulfilled.
In addition, the top end of the tube 21 is in clearance fit with the driving motor 23 through a flange. Ensuring that the body 21 is firmly connected to the drive motor 23 and that the pressure variation in the body 21 above the piston 22 is stable when the piston 22 moves in the body 21.
For the purpose of understanding the technical solution of the utility model, the valve body assembly 3 will be further explained.
The valve body assembly 3 includes: the cavity 31, the plug 32 and the return spring 33 are adjusted.
The plug 32 is located in the adjustment cavity 31, and when the plug is matched with two ends of the adjustment cavity 31, the water supply pipe 1 is opened or closed, and one end of the return spring 33 is connected with the plug 32 for resetting the plug 32.
The plug 32 is normally positioned at the water inlet end of the adjusting cavity 31 under the thrust of the reset spring 33, so that the water supply pipe 1 is closed, and when the water supply pipe 1 is opened, the plug 32 is pushed to the middle position of the adjusting cavity 31 under the action of water flow, so that the water supply pipe 1 is kept to be opened stably. When the water hammer action occurs, the water impact acting force can instantly push the plug 32 to the water outlet end of the adjusting cavity channel 31, the closing of the water supply pipe 1 is realized again, at the moment, the subsequent water can directly flow into the pressure relief straight pipe component 2, and the water hammer is prevented from directly acting on the switch while the pressure relief is realized.
The return spring 33 is located at the water outlet end of the adjustment channel 31, and the other end is connected with a raised stop collar 34. The position of the return spring 33 is also fixed, and the return spring 33 is supported by the supporting function of the limiting ring 34.
The valve body assembly 3 is positioned on the water supply pipe 1 near the pressure relief straight pipe assembly 2. The water which congests the valve body assembly 3 is excessive, and the impact of the water hammer action on the valve body assembly 3 is reduced.
The driving motor 23 is a telescopic motor and is in transmission connection with the piston 22 through a transmission rod 24. Ensuring that the drive motor 23 is operated to adjust the position of the piston 22 via the transmission rod 24.
