Referring to fig. 1 to 10, an accumulator according to a preferred embodiment of the present invention includes a main body 10, a main control valve 20, an elastic energy storage assembly 30, a pilot-operated sub-control 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 control valve 20 includes a main spool 21 movably disposed within the body 10 and cooperating with the main valve port 15. The elastic energy storage component 30 is movably arranged in the energy storage cavity 13. The pilot-operated sub-control valve 40 is provided in the transfer passage 14 to open and close the transfer passage 14.
In the state of water inlet 11 not being filled, main spool 21 closes main valve port 15, and at this time, secondary control valve 40 can selectively close flow passage 14 or open flow passage 14, preferably such that secondary control valve 40 closes flow passage 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, the pilot type auxiliary control valve 40 closes or keeps closing the overflowing channel 14 under the action of the water pressure difference, when the elastic energy storage assembly 30 moves to a preset position, the elastic energy storage assembly 30 is linked to open the pressure relief port 421 of the pilot type auxiliary control valve 40 to open the overflowing channel 14, so that the side, back to the energy storage cavity 13, of the main valve core 21 is acted by the water pressure to open the main valve port 15, 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, and the water flow and the water pressure flowing out of the water outlet 12 are effectively improved.
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 is kept closed to the main valve port 15 under the action of water pressure when the elastic energy storage assembly 30 is not moved to a preset position, so that the main valve element 21 can close the main valve port 15 in the process of storing water in the energy storage device, and therefore water entering the energy storage cavity 13 is prevented from flowing out of the main valve port 15. The sub valve spool 41, which will be described later, closes the sub valve port 141 by its own elastic force, so that the pilot-operated sub control valve 40 closes the excess flow passage 14.
When the overflow channel 14 is open, the mode of automatically opening the main valve port 15 by the main valve element 21 can be designed according to requirements, 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 or less than 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-weight of the main valve element 21. The specific manner of causing main valve element 21 to open main valve port 15 may be designed as desired and is not limited to the above-described embodiment.
Specifically, in this embodiment, main control valve 20 includes first elastic member 22 acting on main valve element 21, and main valve element 21 overcomes the elastic force of first elastic member 22 during the process of closing main valve element 15, that is, when main valve element 21 closes main valve element 15, first elastic member 22 is in an elastic deformation state to apply an elastic force to main valve element 21, and at this time, the elastic force applied to main valve element 21 by first elastic member 22 is smaller than the water inlet pressure of accumulator 13 side to main valve element 21, so as to ensure that main valve element 21 keeps closing main valve element 15 under the action of the water pressure of the inlet water. 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.

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.

When the overflow channel 14 is opened, one side of the main valve element 21, which is back to the energy storage chamber 13, is subjected to water pressure, at this time, the resultant force of the elastic force exerted on the main valve element 21 by the first elastic element 22 and the water pressure exerted on one side of the main valve element 21, which is back to the energy storage chamber 13, is greater than the water pressure exerted on 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 opening 15, at this time, the water in the energy storage chamber 13 is discharged from the main valve opening 15 under the action of the elastic energy storage assembly 30 and flows out from the water outlet 12 together with the water in the water inlet 11, so that the water flow pressure and the water flow rate.
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 as to close the pressure relief opening 421 again, so that 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 pilot type auxiliary control 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 flowing out from the water outlet 12 are improved, and the water flow is stored and pressurized. In addition, the energy accumulator adopts the pilot-operated auxiliary control valve, so that the pilot-operated auxiliary control valve can be opened smoothly with small acting force, and the function is more reliable.
