Detailed Description
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Example 1
As shown in fig. 1, the present embodiment provides a nipple for eliminating the liquid water hammer effect, which includes a short circuit pipe 1, wherein the short circuit pipe 1 is connected to a main pipe through an inlet and an outlet at two ends, and the short circuit pipe 1 is located in front of a valve, a main pipe elbow or a water pump, so as to protect the short circuit pipe 1 from being damaged by water flow impact when the water hammer effect occurs.
The inside of the short circuit pipeline 1 is provided with a special-shaped inner sleeve, and two ends of the special-shaped inner sleeve are respectively communicated with an inlet and an outlet of the short circuit pipeline 1, so that water flows in the special-shaped inner sleeve when passing through the short circuit pipeline 1. The special-shaped inner sleeve comprises a left sleeve 201 and a right sleeve 202, as shown in fig. 1, the left sleeve 201 is connected with the inlet of the short circuit pipeline 1, and the right sleeve 202 is connected with the outlet of the short circuit pipeline 1; adjacent fluid chambers 3 of the left sleeve 201 and the right sleeve 202 are communicated through the connecting pipe 4, so that the whole special-shaped inner sleeve forms a water flow channel. The left sleeve 201 and the right sleeve 202 each comprise at least two communicated fluid cavities 3, and the fluid cavities 3 are in a shape with one wide end and one narrow end, as shown in fig. 1, and the fluid cavities 3 in the embodiment are designed to be similar to a heart-shaped structure; the water flows in the fluid cavity 3, and the water on the upper and lower sides is blocked by the inner wall at the wider end when flowing in the outlet direction, so that the water is forced to flow back and form backflushing convection with the water flowing forward in the middle part, thereby playing a role in stabilizing pressure. When the valve is closed and the water hammer effect occurs, the backflushing convection can slow down the flow velocity of water, thereby protecting the valve, the main pipeline elbow or the water pump at the back.
The short circuit pipeline 1 is also provided with an electromagnetic valve, the electromagnetic valve comprises a coil cavity 5, a coil 501 is arranged in the coil cavity 5, the coil cavity 5 is connected with a flashboard cavity 6, and the flashboard cavity 6 extends into the short circuit pipeline 1 and penetrates through the connecting pipeline 4 and is communicated with the connecting pipeline 4; the ram chamber 6 is connected to one of the fluid chambers 3 of the left 201 and right 202 bushings by left 7 and right 8 conduits, respectively, so that water will also enter the ram chamber 6 when flowing. A flashboard 601 is arranged in the flashboard cavity 6, one end of the flashboard 601 is connected with a lifting rod 9, and the lifting rod 9 stretches into the coil cavity 5 and is arranged in the coil cavity 5 through a first spring 10; the lifting rod 9 is also sleeved with a second spring 11, one end of the second spring 11 is fixed on the flashboard cavity 6, and the other end is fixed on the lifting rod 9. The coil 501 is connected with a power supply through a wire, and two pairs of conductive plates 12 (the conductive plates 12 can be made of copper plates, silver plates and other conductive materials) are arranged on the wire, and the two pairs of conductive plates 12 are respectively positioned at openings of the flashboard cavity 6 corresponding to the left guide pipe 7 and the right guide pipe 8.
When water normally flows, the water entering the flashboard cavity 6 can be used as a conductor to connect the two pairs of conductive sheets 12, so that a power supply smoothly electrifies the coil 501, the coil 501 generates magnetic force to adsorb the first spring 10 and the second spring 11 to compress the first spring and the second spring, and then the lifting rod 9 is pulled to lift, so that the flashboard 601 is positioned above the connecting pipeline 4, the left sleeve 201 and the right sleeve 202 are communicated, and fluid passes through (the normally open state of the electromagnetic valve is realized). When the valve is closed and the water hammer effect occurs, the water flow forms negative pressure due to the local tensile stress, and the gas originally dissolved in the water is supersaturated due to the reduction of the pressure, so that the gas escapes from the water and becomes bubbles (namely cavitation). On the one hand, the water mixed with bubbles is influenced by buffer convection caused by the structure of the fluid cavity 3, and the buffer of the water hammer effect is relieved by larger force generated; on the other hand, bubbles in the liquid can enter the flashboard cavity 6 through the left guide pipe 7 and the right guide pipe 8, so that the conducting strip 12 in the flashboard cavity 6 cannot be communicated and broken, the power supply cannot supply power to the coil 501, and therefore the first spring 10 and the second spring 11 cannot be magnetically attracted, and after the first spring 10 and the second spring 11 are restored to a free state (namely a non-compressed state), the lifting rod 9 drives the flashboard 601 to descend, and finally the connecting pipeline 4 is blocked to cut off water flow, so that a valve, a main pipeline elbow or a water pump and the like at the back are protected from being damaged by impact.
In summary, the nipple of the embodiment not only can play a role in stabilizing the pressure and flow in the pipeline when the water flow normally flows, but also can prevent impact damage to the valve, the main pipeline elbow or the water pump and the like after the water hammer effect occurs.
Example 2
On the basis of embodiment 1, as shown in fig. 1, two diversion blocks 301 are symmetrically disposed in the fluid chamber 3, and the diversion blocks 301 may be designed into an oval strip shape and disposed at one wider end of the fluid chamber 3 in an inclined manner. When fluid flows in the fluid cavity 3, the two diversion blocks 301 divide the fluid into an upper strand, a middle strand and a lower strand, so that the upper and the lower strands of water flow are led to the inner wall of the wider end of the fluid cavity 3, the water flows back after being stressed, then the water flows back to form a reverse opposite impact effect with the water flowing forward, the flow speed of the water flow is reduced, and the effects of stabilizing the pressure and eliminating the water hammer effect are achieved. Therefore, the diversion block 301 of the present embodiment can better enable the water flow to form the reverse opposite flushing phenomenon in the fluid cavity 3, and improve the effects of pressure stabilization and water hammer effect.
Example 3
On the basis of embodiment 1, as shown in fig. 1, the wider ends of the fluid chambers 3 of the left sleeve 201 and the right sleeve 202 face opposite (the wider end of the fluid chamber 3 in the left sleeve 201 faces to the right, and the wider end of the fluid chamber 3 in the right sleeve 202 faces to the left), so that the nipple of the present embodiment can eliminate the water hammer effect in two directions at the same time, that is, eliminate the positive water hammer effect and the reverse water hammer effect at the same time, and the effect is better.
Example 4
On the basis of embodiment 1, as shown in fig. 1, a sealing cornice 13 is arranged at the joint of the flashboard cavity 6 and the connecting pipeline 4, the sealing cornice 13 adopts a steel ring, and the flashboard cavity 6 and the connecting pipeline 4 are welded together through the sealing cornice 13. On the one hand, the sealing cornice 13 plays a role in fixedly connecting the flashboard cavity 6 and the connecting pipeline 4, and on the other hand, the sealing ring of the connecting pipeline 4 can be ensured, so that water is prevented from leaking out.
Example 5
On the basis of the embodiment 1, a sealing cavity 14 is further arranged between the coil cavity 5 and the flashboard cavity 6, and sealing filler is filled in the sealing cavity 14, wherein the sealing filler can be graphite filler. Because the water flow can enter the flashboard cavity 6, a sealing cavity 14 is arranged between the flashboard cavity 6 and the coil cavity 5, and the sealing filler is filled in the sealing cavity 14, so that the sealing performance of the coil cavity 5 can be greatly improved, and the water is prevented from flowing into the coil cavity 5 in the ascending and descending processes of the lifting rod 9.
Although the present utility model has been described in detail by way of preferred embodiments with reference to the accompanying drawings, the present utility model is not limited thereto. Various equivalent modifications and substitutions may be made in the embodiments of the present utility model by those skilled in the art without departing from the spirit and scope of the present utility model, and it is intended that all such modifications and substitutions be within the scope of the present utility model/be within the scope of the present utility model as defined by the appended claims.
