DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-3 The utility model provides the following technical scheme: an oil-water non-mixing type cone valve type hydraulic control water valve, which comprises a valve body 1, first end covers 2 and second end covers 3 are connected to both ends of the valve body 1, first spring seats 4 and second spring seats 5 are connected to one end of the first end covers 2 and the second end covers 3 respectively, first water inlets 6 and second water inlets 7 are arranged on the top of the valve body 1, reset springs 8 are arranged at one end of the first spring seats 4, and water outlets 22 are arranged at the bottom of the valve body 1.

[0023] It should be noted that the outer walls of the first control pistons 9, the water valve cores 10 and the second control pistons 11 are all sleeved with sealing rings.

[0024] One end of the reset spring 8 is provided with the first control piston 9, one end of the first control piston 9 is connected with the water valve core 10, one end of the water valve core 10 is provided with the second control piston 11, two fixed rings 12 are connected to the top of the valve body 1, the inner sides of the two fixed rings 12 are provided with protective covers 13, mounting grooves 14 are formed in the interiors of the protective covers 13, springs 15 are arranged in the interiors of the mounting grooves 14, one end of the spring 15 is connected with a movable block 16, one end of the movable block 16 is connected with a locking pin 17, guide rods 18 are arranged in the interiors of the mounting grooves 14, clamping grooves 19 are formed in the inner walls of the two fixed rings 12, guide rods 18 are arranged in the interiors of the mounting grooves 14, a push block 20 is connected to the top of the movable block 16, oil inlets 21 are formed in the top of the first end covers 2 and the second end covers 3.

[0025] Specifically, when in use, first, when water enters the first water inlet 6, the water valve core 10 will push the first control piston 9 to squeeze the return spring 8. At this time, the water will be located inside the valve body 1. When oil enters the oil filling port 21 on the top of the first end cover 2, the first control piston 9 will push the water valve core 10 and its one end parts to move. At this time, the excess water inside the valve body 1 will be discharged through the drain port 22 at the bottom, thereby achieving the goal of preventing oil and water from mixing inside the cone valve type hydraulically controlled water valve. In addition, the sealing rings sleeved on the outer walls of the first control piston 9, the water valve core 10, and the second control piston 11 can prevent oil and water from mixing with each other, thereby further improving the effect of preventing oil and water from mixing inside the valve.

[0026] It should be noted that, in the initial state, the return spring 8 pushes the first control piston 9, and the water valve core 10 is in a closed state, so that the first water inlet 6 and the second water inlet 7 are disconnected. When the oil filling port 21 on the top of the second end cover 3 is filled with oil, the second control piston 11 pushes the water valve core 10, and the first water inlet 6 and the second water inlet 7 are connected.

[0027] refer to Figure 3 The existing ordinary two-way cartridge hydraulic valve keeps the valve core in a closed state through internal squeezing, but it is easy to cause the following problems during use: the control oil and working water are easily mixed, resulting in control oil emulsification failure and excessive control pressure, which increases proportionally with the increase of water pressure. This province increases the control force by increasing the face value of the control piston. Even if the valve core is stuck due to scale, it can still push the valve core and prevent oil and water from mixing.

[0028] Preferably, the protective cover 13 can form an elastic locking structure with the fixing ring 12 through the mounting groove 14, the spring 15, the movable block 16, the latch 17, and the slot 19. The end of the movable block 16 is sleeved on the outer wall of the guide rod 18, and an opening is opened at the top of the protective cover 13.

[0029] During specific use, through the elastic structure between the fixing ring 12 and the protective cover 13, when the connecting pipes of the first water inlet 6 and the second water inlet 7 are removed, the movable block 16 is moved by the shift block 20, so that the pin 17 can be retracted into the installation groove 14, and then the protective cover 13 is inserted into the interior of the fixing ring 12 and the shift block 20 is released. At this time, the pin 17 will be inserted into the slot 19 under the action of the spring 15, thereby realizing protection at the first water inlet 6 and the second water inlet 7 to prevent dust from entering.

[0030] like Figures 1-4 As shown, in the initial state Pk2·Dk2 2 ·π / 4+Tpre>(DB 2 -DA 2)·PB·π / 4At this time, the valve core is in the closed state, A and B are disconnected, the DA, DB and Dk2 sizes are adjusted, the ideal control pressure can be achieved, when the Pk2 is unloaded, if (DB2-DA2)·PB·π / 4>Tpre, the A port and the B port are connected, which completely solves the problem of mixing of control oil and working water, and by increasing the control piston surface value without increasing the control pressure, the control force is increased, even if the valve core is stuck due to scale, the valve core can still be pushed, therefore, the structure can theoretically achieve no leakage between A and B. The structure is also suitable for gas and other media.

[0031] Working principle: first, through the elastic structure between the fixed ring 12 and the protective cover 13, when the connecting pipe of the first water inlet 6 and the second water inlet 7 is removed, the movable block 16 is pushed by the push block 20, so that the pin 17 can be retracted into the installation slot 14, then the protective cover 13 is inserted into the fixed ring 12, and the push block 20 is loosened, at this time the pin 17 is inserted into the card slot 19 under the action of the spring 15, thereby realizing the protection of the first water inlet 6 and the second water inlet 7 to prevent dust from entering.

[0032] Finally, it should be pointed out that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
