Description

Technical Field

[0001] This utility model relates to the field of electric water valve technology, specifically an antifreeze electric water valve. Background Technology

[0002] Electric water valves are devices suitable for water systems requiring flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning. Electric water valves are classified into constant flow valves and cross-flow regulating valves. Both types of valves use the differential pressure of the fluid as power, automatically changing the resistance coefficient according to changes in system operating conditions to maintain a constant flow rate. By maintaining a constant flow rate in each branch, they achieve balanced flow distribution throughout the system, eliminating uneven heating and cooling. In addition, electric control valves are hydraulically operated valves with solenoid valves as guide valves. They are commonly used in automatic control of water supply, drainage, and industrial systems, featuring accurate and rapid control response and the ability to remotely open and close pipeline systems based on electrical signals.

[0003] Most existing electric water valves do not have antifreeze function. Using electric water valves in low-temperature environments in winter will cause the internal components of the valve body to malfunction due to the low temperature, thus affecting the normal use of electric valves by residents. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes an antifreeze electric water valve.

[0005] The technical solution of this utility model is implemented as follows: an antifreeze electric water valve includes a valve body, an outer shell fixedly connected to the outside of the valve body, an antifreeze mechanism provided on the outer shell, a water tank fixedly connected to one side of the outer shell, an inlet pipe fixedly connected to one end of the water tank, a delivery pipe fixedly connected to one end of the water tank, a first cavity opened inside the water tank, a heating plate fixedly connected inside the first cavity of the water tank, a connecting pipe fixedly connected to one end of the delivery pipe, a fixing pipe fixedly connected to one end of the connecting pipe, a circular hole opened on the outer circular surface of the fixing pipe, and a through hole opened at one end of the delivery pipe.

[0006] Preferably, the outer shell is fixedly connected to the conveying pipe, and the fixed pipe and the connecting pipe are located inside the outer shell.

[0007] Preferably, the through hole on the delivery pipe is connected to the inside of the first cavity on the water tank.

[0008] Preferably, the outer shell is provided with a venting mechanism, a connecting column is fixedly connected to one end of the outer shell, an air inlet is opened at one end of the connecting column, a second cavity is opened inside the connecting column, a ball is movably connected inside the second cavity of the connecting column, a stop block is fixedly connected inside the second cavity of the connecting column, and an air outlet is opened at the other end of the connecting column.

[0009] Preferably, the air inlet on the connecting post is connected to the inside of the outer casing.

[0010] Preferably, the second cavity on the connecting column is located above the sphere.

[0011] Preferably, the bottom of the second cavity on the connecting column is conical.

[0012] Preferably, an electric valve body is fixedly connected to one end of the valve body.

[0013] Preferably, the other end of the outer casing is rotatably connected with a bolt.

[0014] This utility model has the following beneficial effects:

[0015] 1. This antifreeze electric water valve fills the water tank through the inlet pipe. Then, the heating plate heats the water in the tank, turning it into steam. The steam then flows into the fixed pipe through the delivery pipe and connecting pipe. The steam is then injected into the outer casing through the round hole on the fixed pipe, raising the temperature inside the casing and thus insulating the valve body inside the casing from freezing. This prevents the internal components of the electric water valve from malfunctioning due to low temperatures, ensuring that residents can use the electric valve normally.

[0016] 2. This antifreeze electric water valve uses steam to lift the ball in the second cavity on the connecting column, allowing steam inside the outer casing to enter the second cavity on the connecting column through the air inlet and exit through the air outlet. This reduces the steam pressure inside the outer casing and prevents excessive steam pressure from damaging the outer casing. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-6 As shown, the antifreeze electric water valve provided in this embodiment includes a valve body 1, an outer shell 3 fixedly connected to the outside of the valve body 1, an antifreeze mechanism 4 provided on the outer shell 3, a water tank 401 fixedly connected to one side of the outer shell 3, an inlet pipe 402 fixedly connected to one end of the water tank 401, a delivery pipe 403 fixedly connected to one end of the water tank 401, a first cavity 404 opened inside the water tank 401, a heating plate 405 fixedly connected inside the first cavity 404 of the water tank 401, a connecting pipe 407 fixedly connected to one end of the delivery pipe 403, a fixing pipe 406 fixedly connected to one end of the connecting pipe 407, a circular hole 408 opened on the outer circular surface of the fixing pipe 406, and a through hole 409 opened at one end of the delivery pipe 403.

[0027] Furthermore, the outer casing 3 is fixedly connected to the delivery pipe 403, and the fixing pipe 406 and the connecting pipe 407 are located inside the outer casing 3.

[0028] Furthermore, the through hole 409 on the delivery pipe 403 is connected to the interior of the first cavity 404 on the water tank 401.

[0029] By adopting the above technical solution, steam in the first cavity 404 of the water tank 401 is transported through the through hole 409 on the conveying pipe 403.

[0030] Furthermore, the outer casing 3 is provided with a venting mechanism 5. A connecting post 501 is fixedly connected to one end of the outer casing 3. An air inlet 502 is opened at one end of the connecting post 501. A second cavity 503 is opened inside the connecting post 501. A ball 504 is movably connected inside the second cavity 503 of the connecting post 501. A stop block 505 is fixedly connected inside the second cavity 503 of the connecting post 501. An air outlet 506 is opened at the other end of the connecting post 501.

[0031] By adopting the above technical solution, the steam inside the outer casing 3 is released through the venting mechanism 5, thus preventing the steam pressure inside the outer casing 3 from becoming too high.

[0032] Furthermore, the air inlet 502 on the connecting post 501 is connected to the interior of the outer casing 3.

[0033] By adopting the above technical solution, the venting mechanism 5 guides the steam inside the outer casing 3 through the air inlet 502 on the connecting column 501.

[0034] Furthermore, the stop block 505 is located above the sphere 504 within the second cavity 503 on the connecting post 501.

[0035] By adopting the above technical solution, the block 505 intercepts the ball 504, preventing the ball 504 from being blocked by the steam by the steam pushing it to the vent 506 on the connecting column 501.

[0036] Furthermore, the bottom of the second cavity 503 on the connecting column 501 is conical.

[0037] By adopting the above technical solution, the bottom of the second cavity 503 on the connecting column 501 is conical, which makes it easy for the ball 504 to block the air inlet 502 on the connecting column 501, thus preventing the continuous leakage of steam from the outer shell 3.

[0038] Furthermore, an electric valve body 2 is fixedly connected to one end of the valve body 1.

[0039] By adopting the above technical solution, the flow of water in the valve body 1 is controlled by the electric valve body 2.

[0040] Furthermore, the other end of the outer casing 3 is rotatably connected to a bolt 6.

[0041] By adopting the above technical solution, the bolt 6 can be removed from the outer casing 3 by rotating the bolt 6, which facilitates the discharge of steam water accumulated inside the outer casing 3.

[0042] Working principle: To prevent the valve body 1 from freezing, water is injected into the first cavity 404 of the water tank 401 through the water inlet pipe 402. Then, the heating plate 405 in the first cavity 404 of the water tank 401 is activated. The heating plate 405 heats the water in the first cavity 404 of the water tank 401, turning it into steam. At this time, the water flow in the water inlet pipe 402 is reduced to ensure that the water tank 401 always has water and will not be dried out by the heating plate 405. After the water is heated into steam, it flows into the connecting pipe 407 through the through hole 409 on the delivery pipe 403. The connecting pipe 407 then delivers the steam into the fixed pipe 406. Then, the steam is sprayed into the outer shell 3 through the round hole 408 on the fixed pipe 406, which raises the temperature inside the outer shell 3. This keeps the valve body 1 inside the outer shell 3 warm and prevents freezing inside the valve body 1. The component malfunctions due to low temperature. However, as steam continuously sprays into the housing 3 from the round hole 408 on the fixed pipe 406, the steam pressure inside the housing 3 becomes too high. At this time, the steam pressure inside the housing 3 can push up the ball 504 in the second cavity 503 on the connecting post 501. The ball 504 is pushed by the steam to the stop 505 in the second cavity 503 on the connecting post 501. The stop 505 prevents the ball 504 from blocking the vent 506 on the connecting post 501. In this way, the steam inside the housing 3 enters the second cavity 503 on the connecting post 501 from the inlet 502 and then exits from the vent 506 on the connecting post 501. This reduces the steam pressure inside the housing 3 and prevents the housing 3 from being damaged by excessive steam pressure.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
