Description

Technical Field

[0001] This invention relates to the technical field of boiler water supply, and more particularly to an electrode boiler with an automatic water supply valve. Background Technology

[0002] An electrode hot water boiler in a thermal power plant is a boiler device that uses electrical energy as its energy source and converts electrical energy into heat energy using electrodes to provide hot water for the power plant. It mainly consists of electrodes, a water tank, and a control system. In thermal power plants, electricity generated by generators is typically used; a portion is used for power generation, and the remainder is converted into heat energy by the electrode hot water boiler to provide hot water. The electrode hot water boiler heats water to the required temperature through the resistance heating effect generated by the current passing through the electrodes. The heated water can be used for heating, industrial production processes, and other heat energy needs. The application of electrode hot water boilers in thermal power plants is characterized by high efficiency and environmental friendliness, effectively utilizing electrical energy, and is simple, safe, and reliable to operate.

[0003] Most electrode hot water boilers are equipped with automatic water supply systems. These systems monitor the boiler water level through a water level control device and automatically replenish water when the water level is too low. The system can automatically adjust the water supply as needed to maintain a suitable water level. However, this water replenishment method involves components such as sensors, valves, and controllers, which require regular maintenance. If malfunctions are not repaired in time, problems such as excessive water supply, over-discharge, scale buildup, and corrosion can occur, which will not only shorten the service life of the boiler and increase costs, but also pose safety hazards. Summary of the Invention

This process utilizes the principle of pressure balance to drive the valve core, greatly reducing safety hazards. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1 Reference Figure 1 and Figure 2 The first embodiment of the present invention provides an electrode boiler with an automatic water replenishment valve, which includes a boiler unit 100, including a boiler body 101; and a water replenishment control unit 200, including a valve housing 201, a valve core 202, a positioning ring 203, and a sealing plate 204. The valve housing 201 is connected to the outer wall of the boiler body 101 and has a water flow channel in its middle. The positioning ring 203 is fitted into the inner wall of the valve housing 201. The valve core 202 is fitted into the positioning ring 203. The sealing plate 204 is fitted into the valve housing 201 and connected to the valve core 202.

[0032] The boiler body 101 is a prior art, a commonly used electrode hot water boiler in thermal power plants, used to heat cold water discharged from the control water supply unit 200. The valve shell 201 is preferably made of carbon steel, with an anti-corrosion coating on the inner wall. The valve shell 201 is fixed to the outer wall of the boiler body 101 by bolts and communicates with the internal space of the boiler body 101. In order to ensure sealing, a sealing gasket can be added at the connection.

[0033] The main body of the valve core 202, the positioning ring 203, and the sealing plate 204 are all made of stainless steel to prevent rust and water pollution. The positioning ring 203 is rotatably embedded in the valve housing 201, which plays the role of sealing, assisting rotation, and positioning. The valve core 202 is inserted into the valve housing 201 from the cold water inlet end and is in contact with the positioning ring 203. The sealing plate 204 can cooperate to cover the outlet hole of the valve core 202 to ensure the airtightness of the inlet and outlet ends inside the valve housing 201.

[0034] During use, the other end of the valve housing 201 is first connected to the cold water supply unit. The cold water is pressurized and sprayed out from the cold water supply unit, directly impacting the sealing end of the valve core 202. The valve core 202 is pushed into the valve housing 201 by the force, first sliding horizontally and then rotating. During the rotation, the valve core 202 pushes the sealing plate 204 outward, causing it to expand outward and exposing the water flow hole on the valve core 202.

[0035] Furthermore, water flows from the valve core 202 into the valve housing 201, and finally into the boiler body 101 until the water volume in the boiler body 101 reaches the required level. At this time, the pressure regulating valve installed on the boiler body 101 adjusts the internal pressure of the boiler body 101 to be the same as the internal pressure of the cold water supply pipe. At this time, the pressure on the left and right sides of the valve core 202 is balanced, and it is no longer pushed by the cold water. Under the action of the spring, it resets, and the sealing plate 204 re-seals the outer wall of the valve core 202.

[0036] Furthermore, after the hot water in the boiler body 101 is heated and discharged from the boiler body 101, the internal water volume and pressure decrease. At this time, the pressure on the left and right sides of the valve core 202 is unequal, and the cold water will impact the valve core 202 again, causing it to rotate, opening the sealing plate 204, and injecting water into the boiler body 101.

[0037] Example 2 Reference Figures 1-10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: vertical grooves 201a are evenly provided on the inner wall of the valve housing 201 on the side away from the boiler body 101, and threaded grooves 201b are also provided on the inner wall of the valve housing 201 away from its end. The threaded grooves 201b are connected to the vertical grooves 201a. Preferably, four vertical grooves 201a and threaded grooves 201b are provided. Each threaded groove 201b occupies one-quarter of the inner wall of the valve housing 201 and extends spirally into the interior of the valve housing 201.

[0038] A first convex ring 201c and a second convex ring 201d are fixedly connected to the inner wall of the valve housing 201. The second convex ring 201d is located at the bottom of the first convex ring 201c, and a rotation space A is formed between the first convex ring 201c and the second convex ring 201d. At least one set of first springs T1 are vertically fixedly connected to the end of the first convex ring 201c away from the second convex ring 201d. The other end of the first springs T1 is connected to a sealing push ring 201c-1. The axial length of the threaded groove 201b is equal to the length of the first springs T1 and is located on the same side of the first convex ring 201c, which can ensure that the sealing push ring 201c-1 is squeezed the moment it changes from sliding straight to rotating.

[0039] The valve core 202 includes a sealing guide plate 202a and a buffer core 202b. The buffer core 202b is fixedly connected to the middle of one side of the sealing guide plate 202a. At least one set of arc-shaped sliders 202a-1 are fixedly connected to the outer wall of the sealing guide plate 202a along its axial direction. At least one set of water passage holes 202a-2 are also opened in the middle of the arc-shaped sliders 202a-1. The arc-shaped sliders 202a-1 can slide in the vertical slide groove 201a and the threaded slide groove 201b. The buffer core 202b can pass through the middle of the first convex ring 201c, the second convex ring 201d and the sealing push ring 201c-1.

[0040] The sealing guide plate 202a first slides straight along the vertical slide groove 201a, and at the moment of contact with the sealing push ring 201c-1, it changes to a rotating state that slides along the threaded slide groove 201b, and squeezes the sealing push ring 201c-1 while rotating, at which time the first spring T1 contracts.

[0041] At least one set of expansion blocks 201e are uniformly fixedly connected to the inner wall of the end of the valve housing 201 away from the vertical slide groove 201a, preferably eight sets. The expansion blocks 201e and the second convex ring 201d are respectively provided with a first expansion slide groove 201e-1 and a second expansion slide groove 201d-1. The first expansion slide groove 201e-1 and the second expansion slide groove 201d-1 correspond one-to-one. A positioning post 201f is fixedly and vertically connected in both the first expansion slide groove 201e-1 and the second expansion slide groove 201d-1. The extension line of the length direction of the positioning post 201f intersects the axis of the valve housing 201. A second spring T2 is sleeved on the positioning post 201f. The positioning post 201f is oriented directly towards the axis of the valve housing 201.

[0042] The positioning ring 203 includes a ring body 203a, a first positioning element 203b, and a second positioning element 203c. At least one set of the first positioning element 203b and the second positioning element 203c are evenly arranged on the ring body 203a. The ring body 203a can be placed within a rotation space A and rotate flexibly within the rotation space A. The first positioning element 203b includes a first stabilizing post 203b-1, a triangular insert 203b-2, and a third spring T3. The components are uniformly fixedly connected to the inner circumferential wall of the ring 203a. Preferably, four sets are provided. The triangular plug 203b-2 is sleeved on the end of the first stabilizing post 203b-1. The cross-sectional shape of the triangular plug 203b-2 is triangular and has an inclined surface. The third spring T3 is sleeved on the outside of the first stabilizing post 203b-1. Its two ends are connected to the ring 203a and the triangular plug 203b-2. When the triangular plug 203b-2 is compressed, it will contract outward along the first stabilizing post 203b-1.

[0043] The second positioning component 203c includes a base 203c-1, a second stabilizing column 203c-2, an arc-shaped insert 203c-3, and a fourth spring T4. The base 203c-1 is fixedly connected to the inner wall of the ring 203a between adjacent first stabilizing columns 203b-1, preferably in four sets. The second stabilizing column 203c-2 is vertically fixedly connected to one end of the base 203c-1 near the second convex ring 201d, pointing towards the boiler body 101. The arc-shaped insert 203c-3 is set with... The fourth spring T4 is sleeved on the second stabilizing post 203c-2 and connected to the base 203c-1 and the arc-shaped plug-in 203c-3 at both ends. The ends of the second stabilizing post 203c-2 and the arc-shaped plug-in 203c-3 are flush with the ends of the ring 203a. The arc-shaped plug-in 203c-3 can be placed in the second expansion groove 201d-1. The arc edges of the arc-shaped plug-in 203c-3 are rounded on both sides.

[0044] The buffer core 202b is a tubular structure with at least one set of drainage holes 202b-1 evenly distributed on it. A triangular groove 202b-2 is also provided on the circumferential outer wall of the buffer core 202b. A triangular insert 203b-2 can be engaged in the triangular groove 202b-2. When the buffer core 202b is inserted into the first convex ring 201c and continues to move towards the second convex ring 201d, its end will contact the inclined surface of the triangular insert 203b-2, pushing the triangular insert 203b-2 to retract until the triangular insert... When the slot 202b-2 moves to the triangular plug-in 203b-2, the triangular plug-in 203b-2 will pop out and be inserted into the triangular slot 202b-2. When the buffer core 202b rotates with the sealing guide plate 202a, the triangular slot 202b-2 will apply torque to the triangular plug-in 203b-2 and drive the positioning ring 203 to rotate as a whole. At this time, the arc-shaped plug-in 203c-3 will be pushed out from the ring body 203a by the fourth spring T4 and inserted into the corresponding second expansion groove 201d-1.

[0045] The sealing plate 204 includes a plate body 204a, a connecting block 204b, and a crescent block 204c. The plate body 204a has an arc-shaped structure. The crescent block 204c is fixedly connected to the middle of the inner wall of the plate body 204a. The crescent block 204c is rounded near the sealing guide plate 202a. The connecting block 204b is fixedly connected to both ends of the outer wall of the plate body 204a. A stabilizing hole 204b-1 is opened in the middle of the connecting block 204b. The positioning post 201f is inserted into the stabilizing hole 204b-1. The second spring T2 is connected to the top of the connecting block 204b. The crescent block 204c can be inserted into the drain hole 202b-1.

[0046] The remaining structure is the same as that in Example 1.

[0047] During use, initially, the valve core 202 slides along the vertical groove 201a into the valve housing 201 until the sealing guide plate 202a contacts the sealing push ring 201c-1. During this process, the buffer core 202b first pushes the triangular insert 203b-2 to retract, and then contacts the chamfered corner of the crescent block 204c, causing the sealing plate 204 to expand outward as a whole. When the sealing guide plate 202a contacts the sealing push ring 201c-1, the triangular slot 202b-2 just moves to the corresponding position of the triangular insert 203b-2, and the crescent block 204c can just be inserted into the drain hole 202b-1. At this time, the plate 204a can completely seal and block the drain hole 202b-1.

[0048] Furthermore, when water is started to be injected into the boiler, the water flow discharged from the cold water pipe pushes the valve core 202 to continue rotating along the threaded slide groove 201b and moving into the valve housing 201. The triangular groove 202b-2 on the buffer core 202b gives torque to the triangular plug 203b-2, causing the positioning ring 203 to rotate as a whole. During this process, the triangular plug 203b-2 still slides in the triangular groove 202b-2. Meanwhile, the edge of the drain hole 202b-1 pushes the arc-shaped crescent edge of the crescent block 204c, lifting the crescent block 204c upward. At this time, the sealing plate 204 moves upward as a whole, and the connecting block 204b expands outward in the first expansion slide groove 201e-1 and the second expansion slide groove 201d-1 under the limit of the positioning column 201f.

[0049] Furthermore, when the sealing guide plate 202a is displaced to its limit position and can no longer move, the crescent-shaped inclined surface of the crescent block 204c is still in contact with the edge of the drain hole 202b-1. At this time, cold water continuously flows from the water passage hole 202a-2 into the buffer core 202b, and finally enters the valve housing 201 from the drain hole 202b-1, eventually reaching the inside of the boiler.

[0050] Furthermore, during the continuous drainage process, the positioning ring 203 is rotated, and the arc-shaped insert 203c-3 changes from its original state of being retracted into the ring body 203a to extending out from the ring body 203a and inserting into the second expansion groove 201d-1. At this time, the entire positioning ring 203 will be temporarily fixed on the second convex ring 201d.

[0051] Furthermore, when the pressure inside the boiler is balanced with that in the cold water pipe, the forces at both ends of the sealing guide plate 202a are balanced. At this time, under the influence of the elastic force generated by its own reset, the second spring T2 presses down on the connecting block 204b and pushes the plate 204a. The first spring T1 will also push the sealing push ring 201c-1 to reset, so that the sealing guide plate 202a rotates and moves in the opposite direction to the starting point of the threaded groove 201b. During this process, the arc-shaped crescent sidewall of the crescent block 204c pushes the edge of the drain hole 202b-1 to help it rotate and reset. When the valve core 202 rotates and resets as a whole, the arc-shaped insert 203c-3 will also retract into the ring 203a along the second stabilizing column 203c-2 due to the arc-shaped rounded corner treatment at both ends.

[0052] Furthermore, the valve core 202 returns to its initial state, and the plate 204a of the sealing plate 204 still completely seals and covers the drain hole 202b-1. At this time, the internal space of the boiler and the internal space of the cold water pipe are completely isolated by the sealing plate 204.

[0053] Example 3 Reference Figure 3 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a water inlet area B is formed between the first convex ring 201c and the top end of the valve housing 201, and a drainage area C is formed between the second convex ring 201d and the bottom end of the valve housing 201. A first pressure gauge Y1 and a second pressure gauge Y2 are connected to the valve housing 201. The first pressure gauge Y1 is connected to the water inlet area B, and the second pressure gauge Y2 is connected to the drainage area C.

[0054] Compared to Example 2, the first pressure gauge Y1 and the second pressure gauge Y2 are both existing technologies and are pressure measuring instruments. The first pressure gauge Y1 can monitor the pressure in the inlet water zone B and the cold water pipe in real time, and the second pressure gauge Y2 can monitor the pressure in the drainage zone C and the boiler in real time.

[0055] The remaining structure is the same as that in Example 2.

[0056] Combined with reference Figures 1-2 and Figures 4 to 10 It should be noted that when the hot water boiler heats the internal water, the pressure will increase. At this time, the pressure in the drain area C will be greater than that in the inlet area B. Under the pressure, the sealing plate 204 will fit more tightly against the buffer core 202b, and there is no need to worry about the water in the hot water boiler flowing back into the cold water pipe from the drain hole 202b-1.

[0057] Furthermore, when the water temperature inside the boiler reaches the required temperature, it is discharged. At this time, the pressure will drop. The more water is discharged, the lower the pressure will be. According to the above embodiment, before use, it is necessary to balance the pressure between the boiler and the cold water pipe. When the pressure inside the boiler is less than that in the cold water pipe, the cold water can push the valve core 202 to move, thereby opening the gap to add water to the boiler. The speed of adding water depends on the amount of water discharged from the boiler.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
