Referring to fig. 1 to 10, an energy accumulator according to a preferred embodiment of the present invention includes a main body 10, a primary pilot valve 20, an elastic energy accumulating assembly 30, a secondary pilot valve 40, and a transmission mechanism 50.
The body 10 is provided with a water inlet 11, a water outlet 12, an energy storage cavity 13, an overflowing channel 14 for communicating the water inlet 11 with the water outlet 12, and a main valve port 15 for communicating the energy storage cavity 13 with the water outlet 12, wherein the water inlet 11 is communicated with the energy storage cavity 13.
The main pilot valve 20 includes a main valve element 21 movably provided in the main body 10 and engaged with the main valve port 15, and the main valve element 21 controls opening and closing of the main valve port 15.
The secondary pilot valve 40 is disposed on the main body 10 to open and close the overflow passage 14, and when the secondary pilot valve 40 is opened, the outlet water flow of the secondary pilot valve 40 can act on the primary pilot valve 20 to control the opening of the primary pilot valve 20. Specifically, the overflow path 14 is formed with a sub-valve port 141, the sub-pilot valve 40 controls the opening and closing of the sub-valve port 141, and when the sub-valve port 141 is opened, water in a cavity between the sub-valve port 141 and the water outlet 12 acts on a side of the main valve element 21 facing away from the energy storage cavity 13, so that the main valve element 21 opens the main valve port 15.
The elastic energy storage assembly 30 is movably arranged in the energy storage cavity 13, and after the main valve port 15 is opened, the elastic energy storage assembly 30 releases elastic potential energy to push water in the energy storage cavity 13 to be discharged through the main valve port 15 and the water outlet 12 in sequence, so that energy storage and pressurization of water flow are realized.
When the water inlet 11 is not filled with water, the elastic energy storage assembly 30 releases elastic potential energy and abuts against the main valve core 21 to enable the main valve core 21 to close the main valve port 15, at this time, the secondary pilot valve 40 can selectively close the overflow channel 14 or open the overflow channel 14, and preferably enables the secondary pilot valve 40 to close the overflow channel 14. When water enters the water inlet 11, water flows into the energy storage cavity 13 by overcoming the elastic force of the elastic energy storage assembly 30 and drives the elastic energy storage assembly 30 to store energy in the elastic energy storage assembly 30, one side of the main valve element 21, which is located in the energy storage cavity 13, keeps closing the main valve port 15 under the action of water pressure in the energy storage cavity 13, and the auxiliary pilot valve 40 closes or keeps closing the overflowing channel 14 under the action of water pressure difference.
Preferably, in order to make the use more convenient, when the elastic energy storage assembly 30 moves to a predetermined position in the energy storage process, the elastic energy storage assembly 30 is linked to open the pressure relief port 421 of the secondary pilot valve 40 to open the overflow channel 14, so that one side of the main valve element 21, which faces away from the energy storage cavity 13, is subjected to the action of water pressure to open the main valve port 15, and then the water in the energy storage cavity 13 is discharged from the main valve port 15 under the action of the elastic energy storage assembly 30 and flows out of the water outlet 12 together with the water in the water inlet 11, so that the water flow pressure and the water flow rate flowing out of the water outlet 12 can be effectively improved. In other embodiments, the secondary pilot valve 40 may be opened by direct manual or electronic control to open the overflow passage 14, so that the side of the main spool 21 facing away from the energy storage chamber 13 is exposed to hydraulic pressure to open the main valve port 15.
Specifically, in the present embodiment, the body 10 includes a main body 10a and a top cover 10b, an energy storage cavity 13 is formed in the main body 10a, a water inlet channel 17 is formed on the top cover 10b, and an overflowing channel 14, a water inlet 11, a water outlet 12 and a main valve port 15 are formed on the top cover 10 b. The water inlet 11 forms a water inlet end of the water inlet channel 17, a water outlet end of the water inlet channel 17 is divided into a first water outlet end 171 and a second water outlet end 172, the first water outlet end 171 is communicated with the energy storage cavity 13, and the water inlet 11 is communicated with the energy storage cavity 13 through the water inlet channel 17 and the first water outlet end 171. The second water outlet end 172 is communicated with the overflow channel 14, and the water inlet 11 is communicated with the overflow channel 14 through the water inlet channel 17 and the second water outlet end 172.
In this embodiment, when the water inlet 11 is not filled with water, the elastic energy storage assembly 30 abuts against the main valve element 21 so that the main valve element 21 closes the main valve port 15; when the water inlet 11 is filled, the main valve element 21 keeps closing the main valve port 15 under the action of the water pressure in the energy storage chamber 13 when the elastic energy storage assembly 30 is not moved to a predetermined position, so that the main valve element 21 can close the main valve port 15 during the storage of water in the energy storage device, thereby preventing the water entering the energy storage chamber 13 from flowing out of the main valve port 15. When the water inlet 11 is not filled with water, the below-described auxiliary valve element 41 closes the auxiliary valve port 141 under the action of its own elastic force, so that the auxiliary pilot valve 40 closes the overflow channel 14, and when the water inlet 11 is filled with water, the auxiliary valve element 41 continues to close the overflow channel 14 under the action of the water pressure difference.
When the secondary pilot valve 40 controls the overflow channel 14 to open, the water pressure on the side of the main valve element 21 opposite to the energy storage cavity 13 can counteract or partially counteract the water pressure on the side of the main valve element 21 located in the energy storage cavity 13, at this time, the mode of automatically opening the main valve port 15 by the main valve element 21 can be designed according to the needs, for example: the main valve port 15 is opened by the main valve element 21 under the action of an external force acting on the main valve element 21, or the main valve port 15 is opened by the main valve element 21 under the action of its own weight, or the like. Specifically, when the flow passage 14 is opened, the side of the main valve element 21 facing away from the energy storage chamber 13 is subjected to water pressure, and when the water pressure applied to the side of the main valve element 21 facing away from the energy storage chamber 13 is equal to (offset) or less than (partially offset) the water pressure applied to the side of the main valve element 21 located in the energy storage chamber 13, the main valve element 21 can automatically open the main valve port 15 by an external force acting on the main valve element 21 or by the self-gravity of the main valve element 21. The specific manner of opening main valve port 15 by main valve element 21 may be designed as needed, and the above embodiment is not limited as long as the direction of resultant force applied to main valve element 21 when secondary pilot valve 40 is opened is the direction of opening main valve port 15.
Specifically, in this embodiment, the main pilot valve 20 includes a first elastic member 22 acting on the main valve element 21, and the elastic force of the first elastic member 22 is overcome during the process of closing the main valve opening 15 by the main valve element 21, that is, when the main valve element 21 closes the main valve opening 15, the first elastic member 22 is in an elastic deformation state to apply an elastic force to the main valve element 21, and at this time, the elastic force applied to the main valve element 21 by the first elastic member 22 is smaller than the water inlet pressure of the accumulator 13 side to the main valve element 21, so as to ensure that the main valve element 21 keeps closing the main valve opening 15 under the action of the water inlet pressure. When the overflow passage 14 is opened, the resultant of the elastic force exerted by the first elastic member 22 on the main valve element 21 and the water pressure exerted on the side of the main valve element 21 facing away from the accumulator 13 is greater than the water pressure exerted on the side of the main valve element 21 on the accumulator 13, and the main valve element 21 opens the main valve port 15 under the action of the external force provided by the first elastic member 22. The main valve spool 21 automatically opens the main valve port 15 by the elastic external force provided by the first elastic member 22, which is more reliable.

In this embodiment, the elastic energy storage assembly 30 opens the pressure relief port 421 of the secondary pilot valve 40 through the transmission mechanism. The auxiliary pilot valve 40 includes an auxiliary valve cover 42 and an auxiliary valve core 41 matched with the auxiliary valve port 141, the auxiliary valve core 41 is an elastic rubber pad, a back pressure cavity 43 is formed between the auxiliary valve core 41 and the auxiliary valve cover 42, the pressure relief port 421 is communicated with the back pressure cavity 43, the back pressure cavity 43 is communicated with the flow passage 14 on the water inlet 11 side through a flow passage 44 and further communicated with the water inlet 11, and water flow of the water inlet 11 flows into the back pressure cavity 43 through the flow passage 14 and the flow passage 44. When the relief port 421 is opened, the sub-valve body 41 opens the sub-valve port 141 under the action of the pressure of the inlet water, and when the relief port 421 is closed, the sub-valve body 41 closes the sub-valve port 141 under the action of the difference in the pressure of the water received on both sides of the sub-valve body 41. The operation principle of the secondary pilot valve 40 using the pressure difference is well known in the art, and the operation principle thereof will not be described in detail herein.
Preferably, when the elastic energy storage assembly 30 loses the acting force on the transmission mechanism, the transmission mechanism closes the pressure relief opening 421 of the secondary pilot valve 40 under the action of gravity. In order to close the pressure relief opening 421 more reliably and timely, a third elastic element 55 may be further provided, where the third elastic element 55 acts on the push rod 52, so that the transmission mechanism 50 is reset and closes the pressure relief opening 421 after losing the acting force of the elastic energy storage assembly 30.
Preferably, as shown in fig. 1, 3 and 4, the transmission mechanism 50 includes a swing rod 51, a push rod 52 and a lifting rod 54, the swing rod 51 is swing-mounted on a side wall of the energy storage cavity 13 through a rotating shaft 53, one end of the swing rod 51 is in linkage fit with the elastic energy storage assembly 30, the other end of the swing rod 51 is in linkage fit with the push rod 52, the push rod 52 is in linkage fit with one end of the lifting rod 54, and the other end of the lifting rod 54 is in open-close fit with the pressure relief port 421 of the secondary pilot valve 40. The transmission mechanism is simple and reliable in transmission.
In order to make the overall layout of the energy accumulator reasonable, the structure is compact, and the forming is convenient, in this embodiment, an energy storage cavity 13 is formed in the main body 10a, the overflow channel 14, the water inlet 11, the water outlet 12 and the main valve port 15 are formed on the top cover 10b, the main pilot valve 20 is installed in the main body 10a, and the auxiliary pilot valve 40 is installed on the top cover 10 b. The top cover 10b is further provided with a guide groove 18, and the main valve element 21 is provided with a guide rod 211 which is in sliding guide fit with the guide groove 18.
In this embodiment, the first elastic member 22, the second elastic member 32, and the third elastic member 55 are compression springs. And the elastic force of the second elastic member 32 is greater than that of the first elastic member 22.
In use, in an initial state, water is not supplied to the water inlet 11, at this time, the main valve element 21 closes the main valve port 15, and the secondary pilot valve 40 closes the overflow passage 14. Referring to fig. 2 and 3, when water inlet 11 begins to fill, water flows into energy storage chamber 13 against the elastic force of elastic energy storage assembly 30, and main valve element 21 is held closed against the elastic force of first elastic element 22 by the water pressure in energy storage chamber 13. As the water flow continuously enters the energy storage cavity 13, the water flow drives the elastic energy storage assembly 30 to make the piston 31 of the elastic energy storage assembly 30 move downwards and compress the second elastic element 32 for storing energy. In this process, the secondary valve core 41 of the secondary pilot valve 40 keeps closing the secondary valve port 141 under the action of the water pressure difference on the two sides of the secondary valve core 41, and the overflow channel 14 keeps a closed state, so that the water flow of the water inlet 11 cannot flow to the water outlet 12 through the overflow channel 14.
Referring to fig. 4 and 5, when the elastic energy storage assembly 30 moves to a predetermined position, the piston rod 312 of the elastic energy storage assembly 30 starts to abut against one end (i.e., the left end in fig. 4) of the swing rod 51 of the transmission mechanism 50 downward, so as to drive the swing rod 51 to swing, the other end (i.e., the right end in fig. 4) of the swing rod 51 moves upward and drives the push rod 52 to move upward against the acting force of the third elastic element 55, the push rod 52 drives the lifting rod 54 to lift upward, so that the back pressure pad 541 provided on the lifting rod 54 opens the pressure relief opening 421, the auxiliary valve core 41 moves upward under the action of the water pressure to open the auxiliary valve port 141, so as to open the overflow channel 14, and the water flow of the water inlet 11 can flow to the water outlet 12 through the overflow channel 14.
When the overflow channel 14 is opened, water in the cavity between the auxiliary valve port 141 and the water outlet 12 acts on one side of the main valve element 21, which faces away from the energy storage chamber 13, so that one side of the main valve element 21, which faces away from the energy storage chamber 13, is subjected to a water pressure action, at this time, the resultant force of the elastic force exerted by the first elastic element 22 on the main valve element 21 and the water pressure exerted by one side of the main valve element 21, which faces away from the energy storage chamber 13, is greater than the water pressure exerted by one side of the main valve element 21, which is located on the energy storage device 13, taking the direction of fig. 4 as an example, the main valve element 21 moves downward and opens the main valve port 15, at this time, water in the energy storage chamber 13 is discharged from the main valve port 15 under the action of the elastic energy storage assembly 30 and flows out of the water outlet 12 together with water from the water inlet 11.
After the water in the energy storage chamber 13 is discharged, since the elastic force of the second elastic element 32 is greater than the elastic force of the first elastic element 22, the elastic energy storage assembly 30 re-abuts against the main valve element 21 so that the main valve element 21 can be located at a position for closing the main valve port 15 against the elastic force of the first elastic element 22. Meanwhile, after the elastic energy storage assembly 30 is reset, the contact with the swing rod 51 of the transmission mechanism 50 is lost, and the lifting rod 54 swings downwards under the combined action of the gravity of the lifting rod 54, the gravity of the push rod 52 and the elastic force of the third elastic element 55, so that the back pressure pad 541 closes the pressure relief opening 421 again, and the energy storage device is restored to the initial state.
Wherein the arrows in fig. 2, 4 and 5 indicate the water flow direction.
When the water inlet 11 begins to feed water, the water flow of the water inlet 11 is firstly stored in the energy storage cavity 13 of the energy storage device, when the water in the energy storage cavity 13 is stored to a preset amount and the elastic energy storage assembly 30 moves to a preset position, the linkage auxiliary pilot valve opens the overflowing channel 14, so that the main valve port 15 is opened, the water in the energy storage cavity 13 can flow out through the main valve port 15 and flow out from the water outlet 12 together with the water in the water inlet 11, the water flow pressure and the water flow quantity flowing out from the water outlet 12 are improved, and the water flow is stored and pressurized. In addition, the energy accumulator of the invention adopts two-stage pilot valves to control the opening of the main valve port 15, and only a small acting force is needed to open the auxiliary pilot valve, thus the function is more reliable.
