Description

Technical Field

[0001] The utility model relates to the technical field of electronic drain valves, in particular to a high-pressure and large-flow electronic drain valve. Background Technique

[0002] The electronic drain valve matches an analog circuit solid-state electronic timer with a solenoid valve to realize the timed automatic discharge of condensed water in the compressed air system. The high-pressure electronic drain valve is widely used in components of the compressed air system such as filters, separators, dryers, gas storage tanks, and drip legs. The discharge time and interval time can be adjusted according to different needs.

[0003] For example, the patent document with the publication number CN 213298998 U discloses an adjustable electronic timing drain valve, which includes a valve body, and an installation block is movably connected to the right side of the valve body. For this adjustable electronic timing drain valve, by rotating the worm, the worm gear rotates. After the worm gear rotates, the threaded lead screw moves downward, and the bottom plate moves downward driven by the threaded lead screw. Through a series of mechanical structures, the bottom plate can move downward after the valve body is installed, and after the bottom plate moves downward, it can contact the connecting pipe, playing a supporting role to avoid the situation of unstable installation of the valve body. By pulling the movable rod upward, after the movable rod moves upward, it separates from the fixed card slot. After the movable rod separates from the fixed card slot, by pulling out the installation block to the right, after the installation block is pulled, the installation connecting block separates from the installation groove, and the installation block can be separated from the valve body. Through a series of mechanical structures, the valve body and the installation block are easy to disassemble.

[0004] However, when this structure is used for draining water with high pressure and large flow, the spool assembly inside often can only resist the water pressure through its own material strength. After long-term use, the large-flow water pressure will cause the concentrated bearing capacity of the spool to be filtered, and there is a high risk of internal fracture and damage. At the same time, the device cannot accurately monitor the pressure in each area inside, and cannot meet the daily use requirements. Therefore, it is urgent to design a high-pressure and large-flow electronic drain valve to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-pressure and large-flow electronic drain valve to solve the problem that in the background technique, when the existing structure is used for draining water with high pressure and large flow, the spool assembly inside often can only resist the water pressure through its own material strength. After long-term use, the large-flow water pressure will cause the concentrated bearing capacity of the spool to be filtered, and there is a high risk of internal fracture and damage. At the same time, the device cannot accurately monitor the pressure in each area inside, and cannot meet the daily use requirements.

[0006] To achieve the above object, the present utility model provides the following technical solution: A high-pressure and large-flow electronic drain valve, comprising a valve body, a liquid inlet seat is fixedly connected to the front surface of the valve body, a liquid discharge seat is fixedly connected to the back surface of the valve body, liquid inlet arc frames are fixedly connected to the upper and lower ends of the liquid discharge seat, and liquid outlet arc frames are fixedly connected to the upper and lower ends of the liquid discharge seat;

[0007] A receiving cover, receiving covers are fixedly connected to both the upper and lower ends of the valve body, a rotating disk is arranged at the top of the top receiving cover, and a two-way valve rod is arranged at the bottom end of the rotating disk.

[0008] Preferably, two groups of valve cores are respectively sleeved on the upper and lower parts of the outer surface of the two-way valve rod, and a sealing ring is arranged between the two groups of valve cores.

[0009] Preferably, a flow guiding center seat is fixedly connected between the liquid inlet arc frame and the liquid outlet arc frame, and a flow guiding pipe is fixedly connected between the flow guiding center seats.

[0010] Preferably, a monitoring seat is arranged between the two groups of flow guiding center seats, and a water pressure gauge is arranged inside the monitoring seat.

[0011] Preferably, arc-shaped flow guiding seats are arranged inside the liquid inlet arc frame and the liquid outlet arc frame, and arc-shaped grilles are arranged on the front surface of the arc-shaped flow guiding seats.

[0012] Preferably, a connection seat is arranged inside the liquid inlet seat, and an annular grille is arranged on the inner wall of the connection seat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] For this high-pressure and large-flow electronic drain valve, by setting the valve body, liquid inlet seat, liquid discharge seat, liquid inlet arc frame, liquid outlet arc frame, arc-shaped flow guiding seat, arc-shaped grille, connection seat and annular grille, when the device drains high-pressure and large-flow water, the internal force is more uniform and safe. During the actual use process, the staff first connects the water inlet pipe to be used to the liquid inlet seat and the water outlet pipe to the liquid discharge seat. At this time, the connection seats designed inside the liquid inlet seat and the liquid discharge seat can evenly distribute or converge the respective water flows with the liquid inlet arc frame and the liquid outlet arc frame at the annular grille. The large-flow water can be evenly distributed by the arc-shaped flow guiding seat and the arc-shaped grille inside the liquid inlet arc frame and the liquid outlet arc frame respectively, so that the impact force of the water flow is always in a uniform force application state inside the valve body. Especially in the on-off state inside the valve body, such a design effectively ensures that the impact force of the water flow on the device becomes uniform, and more safely and reliably completes the control and drainage operation of high-pressure and large-flow water, reflecting the practicability of the device design.

[0015] The high-pressure and large-flow electronic drain valve further improves the overall use effect of the equipment through the set valve body, storage cover, rotating disk, two-way valve rod, valve core, sealing ring, diversion center seat, diversion pipe, monitoring seat and water pressure gauge. During daily use, the staff can turn the rotating disk at the top of the storage cover to drive the overall rotation adjustment of the two-way valve rod in the center of the valve body, adjust the upper and lower groups of valve cores and sealing rings to the center of the valve body, so as to perform the on-off operation of docking inside the valve body, and also make the two groups of valve cores fit and dock with the arc-shaped grille of the arc-shaped diversion seat to reduce the impact of high-pressure and large-flow water. At the same time, the diversion center seats at the four corners on both sides can conduct water pressure tests on the four regions inside the valve body through the diversion pipes and the water pressure gauges on the monitoring seats, which effectively ensures the safety monitoring inside the valve body and reflects the comprehensiveness of the equipment design.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0023] A high-pressure and large-flow electronic drain valve, comprising a valve body 1. A liquid inlet seat 2 is fixedly connected to the front surface of the valve body 1. A liquid discharge seat 3 is fixedly connected to the back surface of the valve body 1. Liquid inlet arc frames 4 are fixedly connected to the upper and lower ends of the liquid discharge seat 3. Liquid outlet arc frames 5 are fixedly connected to the upper and lower ends of the liquid discharge seat 3. An arc-shaped flow guide seat 15 is arranged inside the liquid inlet arc frames 4 and the liquid outlet arc frames 5. An arc-shaped grid 16 is formed on the front surface of the arc-shaped flow guide seat 15. A connection seat 17 is arranged inside the liquid inlet seat 2. An annular grid 18 is formed on the inner wall of the connection seat 17 to evenly divert or converge the respective water flows to the liquid inlet arc frames 4 and the liquid outlet arc frames 5. Under the uniform diversion of the arc-shaped flow guide seat 15 and the arc-shaped grid 16 inside the liquid inlet arc frames 4 and the liquid outlet arc frames 5, the impact force of the large-flow water can always be in a state of uniform force application inside the valve body 1.

[0024] A storage cover 6 is fixedly connected to both the upper and lower ends of the valve body 1. A rotating disk 7 is arranged on the top of the top storage cover 6. A two-way valve rod 8 is arranged at the bottom end of the rotating disk 7. Two groups of valve cores 9 are respectively sleeved on the upper and lower parts of the outer surface of the two-way valve rod 8. A sealing ring 10 is arranged between the two groups of valve cores 9. A flow guide center seat 11 is fixedly connected between the liquid inlet arc frames 4 and the liquid outlet arc frames 5. A flow guide pipe 12 is fixedly connected between the flow guide center seats 11. A monitoring seat 13 is arranged between the two groups of flow guide center seats 11. A water pressure gauge 14 is arranged inside the monitoring seat 13. Turn the rotating disk 7 on the top of the storage cover 6 to drive the overall rotation adjustment of the two-way valve rod 8 at the center inside the valve body 1, adjust the upper and lower two groups of valve cores 9 and the sealing ring 10 to the center inside the valve body 1, so as to perform the on-off operation of docking inside the valve body 1, and also make the two groups of valve cores 9 be adaptively docked with the arc-shaped grid 16 of the arc-shaped flow guide seat 15 to reduce the influence of high-pressure and large-flow water.

[0025] Working principle: When in use, the user first connects the water inlet pipe to be used to the liquid inlet seat 2 and the water outlet pipe to the liquid discharge seat 3. At this time, the connecting seat 17 designed inside the liquid inlet seat 2 and the liquid discharge seat 3 can evenly distribute or converge the respective water flows at the annular grid 18 to the liquid inlet arc frame 4 and the liquid outlet arc frame 5. Under the uniform distribution of the large-flow water by the arc-shaped guide seat 15 and the arc-shaped grid 16 inside the liquid inlet arc frame 4 and the liquid outlet arc frame 5 respectively, the impact force of the water flow is always in a uniform force application state inside the valve body 1. Especially in the on-off state inside the valve body 1, such a design effectively ensures that the impact force of the equipment by the water flow becomes uniform, and more safely and reliably completes the control and drainage operation of high-pressure and large-flow water. During daily use, the staff can turn the rotating disk 7 at the top of the storage cover 6 to drive the overall rotation adjustment of the two-way valve stem 8 at the center inside the valve body 1, adjust the upper and lower groups of valve cores 9 and the sealing rings 10 to the center inside the valve body 1, so as to perform the on-off operation of docking inside the valve body 1, and also make the two groups of valve cores 9 adaptively dock with the arc-shaped grid 16 of the arc-shaped guide seat 15 to reduce the impact of high-pressure and large-flow water. At the same time, the flow guiding center seats 11 at the four corners on both sides can perform the water pressure test of the four areas inside the valve body 1 through the flow guiding pipes 12 and the water pressure gauges 14 on the monitoring seats 13, which effectively guarantees the safety monitoring inside the valve body 1. The above is all the working principle of the present utility model.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
