Description

Technical Field

[0001] The utility model relates to the technical field of electric water valves, in particular to an electric water valve safety control device. Background Art

[0002] An electric water valve is a device suitable for use in water systems that require flow control, and is particularly suitable for flow control of non-corrosive liquid media such as heating and air conditioning. Electric water valves are categorized into fixed-flow valves and cross-flow regulating valves. Both valves use the differential pressure of the fluid as their driving force, automatically changing the resistance coefficient according to changes in the system's operating conditions to maintain a constant flow rate. By maintaining a constant flow rate in each branch, the flow rate of the entire system is balanced, eliminating uneven heating and cooling. In addition, an electric control valve is a hydraulically operated valve with a solenoid valve as its guide valve. It is commonly used for automatic control in water supply and drainage and industrial systems, and features accurate and rapid control response, and the ability to remotely open and close pipeline systems based on electrical signals.

[0003] During use, the existing electric water valve cannot be closed due to a fault, and water continues to flow through the electric water valve that cannot be closed, which may aggravate the wear of the internal components of the valve and thus reduce the service life of the electric water valve.

[0013] The utility model has the following beneficial effects:

[0014] The electric water valve safety control device pulls the twisting block upward, and the twisting block drives the rotating column to disengage the blocking block from the slot on the fixed seat, and the blocking block is completely moved into the straight groove on the connecting column. Then, the twisting block is rotated, and the twisting block drives the connecting column to rotate 90 degrees through the blocking block on the rotating column.

[0024] Furthermore, the groove 306 on the baffle 304 is slidably connected to the connecting seat 302 and the fixing seat 305 .

[0025] By adopting the above technical solution, when the baffle 304 rotates 90 degrees, the groove 30 on the baffle 304 fits the connecting seat 302 and the fixing seat 305 to prevent water from seeping out from between the baffle 304 and the connecting seat 302 and the fixing seat 305.

[0026] Furthermore, the clamping block 310 is in a cross shape as a whole. The clamping block 310 is located inside the circular hole 307 on the connecting column 303 , and the clamping block 310 is slidably connected to the straight groove 308 on the connecting column 303 .

[0027] By adopting the above technical solution, the connecting post 303 is driven to rotate by the clamping block 310 in the straight groove 308 on the connecting post 303 .

[0028] Furthermore, the latching slot 312 on the fixing seat 305 is in a cross shape as a whole and corresponds to the latching block 310 .

[0029] By adopting the above technical solution, the connecting column 303 cannot rotate by inserting the clamping block 310 into the clamping groove 312 on the fixing seat 305.

[0030] Furthermore, the baffle 304 is semicircular, and the semicircular edge is arc-shaped.

[0031] By adopting the above technical solution, the semicircular edge of the baffle 304 is arc-shaped, so that the baffle 304 will not be hindered from rotating in the through hole 2 on the valve body 1.

[0032] Furthermore, one end of the valve body 1 is fixedly connected to the electric valve body 4 .

[0033] By adopting the above technical solution, the flow of water in the valve body 1 is controlled by the electric valve body 4 .

[0034] Furthermore, one end of the fixing seat 305 is fixedly connected to the limiting block 5 .

[0035] By adopting the above technical solution, the baffle 304 is limited in rotation by the limit block 5 so that the baffle 304 can only rotate 90 degrees.

[0036] Furthermore, a sealing gasket 6 is fixedly connected inside the circular groove 311 on the fixing seat 305, a corresponding groove corresponding to the connecting column 303 is opened in the connecting seat 302, and a sealing gasket 6 is arranged therein, and the rotating column 309 is slidably connected to the circular hole 307 on the connecting column 303.

[0037] By adopting the above technical solution and providing the sealing gasket 6 , water is prevented from seeping into the circular hole 307 on the connecting column 303 from between the rotating column 309 and the connecting seat 302 .

[0038] Working principle: When the electric valve body 4 cannot control the closing of the valve body 1, the twisting block 301 is pulled upward, and the twisting block 301 will drive the rotating column 309 to slide upward in the circular groove 311 on the fixed seat 305, and the rotating column 309 will drive the clamping block 310 to move upward, so that the clamping block 310 disengages from the clamping groove 312 on the fixed seat 305, and the clamping block 310 is completely moved into the straight groove 308 on the connecting column 303. Then, the twisting block 301 is rotated 90 degrees, and the twisting block 301 drives the connecting column 303 to rotate 90 degrees through the clamping block 310 on the rotating column 309. The top of the connecting column 303 rotates in the corresponding groove of the connecting column 303, and the bottom of the connecting column 303 rotates in the circular groove 311 on the fixed seat 305, and the corresponding groove of the connecting column 303 and the circular groove 311 on the fixed seat 305 are both The sealing gasket 6 will prevent water from seeping out when the connecting column 303 is rotated. The connecting column 303 will drive the baffle 304 to rotate 90 degrees. Since the block 310 and the slot 312 on the fixing seat 305 are both "cross" shaped, the block 310 still corresponds to the slot 312 on the fixing seat 305 after rotating 90 degrees. In this way, the twisting block 301 is pressed downward, and the twisting block 301 will insert the block 310 into the slot 312 on the fixing seat 305 through the rotating column 309. Part of the block 310 is located in the straight groove 308 on the connecting column 303, and the other part is located in the slot 312 on the fixing seat 305. This will prevent the baffle 304 from rotating when the water flow hits the baffle 304, so that the baffle 304 will block the through hole 2 on the valve body 1, so that the water flow cannot flow, thereby avoiding wear on the internal components of the valve body 1.

[0039] 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
