[0001] The utility model relates to the technical field of foot valves, in particular to an anti-corrosion direct-operated foot valve. Background Art

[0002] The foot valve is usually composed of a valve body, a valve core, a spring, a pedal and other auxiliary devices. The valve body is the outer shell of the entire valve, usually made of metal, with a certain strength and corrosion resistance. The valve core is a key component of the valve, which is controlled by stepping on the valve to open and close. The spring applies a certain force to the valve core to keep it in an open or closed state.

[0003] The current valve body structure has poor anti-corrosion performance. Over time, the valve body is prone to corrosion. In severe cases, the valve body may even leak, which in turn affects the normal operation of the valve body. The control accuracy of the direct-operated foot valve is relatively low, and it is not suitable for occasions with high flow requirements. It is difficult to accurately control the size of the valve body opening by the foot pedal. Summary of the invention

[0021] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 5 shown, an anti-corrosion straight-step foot valve includes a valve body 1 and a reset mechanism 10. Flange plates 2 are provided on both the left and right sides of the valve body 1. A protection mechanism 4 is provided on the outer side of the valve body 1. The protection mechanism 4 covers and protects the outer side of the valve body 1 to prevent corrosive liquids from corroding the valve body 1, thereby affecting the stability of the valve body 1 during frequent lifting and lowering, as the corrosive liquid affects the stability of the valve body 1. The reset mechanism 10 vertically lifts and lowers the valve core 14 during use, and then drives the valve core 14 to perform vertical reset through internal components.

[0023] In this embodiment, the protection mechanism 4 includes a rubber cover body 3, a threaded rod 5, a downward pressure sleeve 6, a foot pedal 7 and a nut 8. The threaded rod 5 is connected through the outer side of the rubber cover body 3. One side of the threaded rod 5 is connected through the top end of the downward pressure sleeve 6. The tail end of the threaded rod 5 is connected with a nut 8. A foot pedal 7 is provided directly above the downward pressure sleeve 6. The rubber cover body 3 is arranged inside the valve body 1. The downward pressure sleeve 6 drives the valve rod 9 to move vertically downward to control the liquid flow rate of the valve body 1.

[0024] In this embodiment, the valve body 1 is connected to the top end of the rubber cover body 3 through symmetrically connected threaded rods 5. The rubber cover body 3 is locked by the threaded rods 5 to prevent corrosive liquids from damaging the valve body 1.

[0025] In this embodiment, the reset mechanism 10 includes a valve rod 9, a force-receiving disc 11, a spring column 12, a ring gasket 13, a valve core 14 and a ring groove 15. The top end of the valve rod 9 is connected to the bottom end of the foot pedal 7. A spring column 12 is arranged inside the downward pressure sleeve 6. The spring column 12 is connected through the valve rod 9. The bottom end of the valve rod 9 is connected with a valve core 14. A ring gasket 13 is connected to the outer side of the valve core 14. A ring groove 15 is formed inside the valve body 1. A force-receiving disc 11 is provided directly above the spring column 12.

[0026] In this embodiment, the foot pedal 7 is connected to the top end of the force-receiving disc 11 through the downward pressure sleeve 6 provided at the bottom end. The downward pressure sleeve 6 vertically moves the force-receiving disc 11 downward to close the valve body 1.

[0027] In this embodiment, the force-receiving disc 11 is connected to the inside of the valve body 1 through the spring column 12 provided at the bottom end. The spring column 12 vertically resets the foot pedal 7 to facilitate the adjustment and control of the opening scale.

[0028] When this anti-corrosion straight-step foot valve is actually applied, it includes the following working contents:

[0029] Step 1: The operator first installs the rubber cover 3 at the top of the valve body 1, passes the threaded rod 5 through the top of the rubber cover 3, and rotates the nut 8 at the bottom of the threaded rod 5 to lock the outside of the rubber cover 3. The rubber cover 3 covers the connection between the valve body 1 and the valve body 1 and the lower pressure sleeve 6 to prevent external liquid from directly entering the connection between the valve body 1 and the lower pressure sleeve 6 during the stepping process;

[0030] Step 2: During use, the operator steps on the foot pedal 7 with the foot, drives the lower pressure sleeve 6 to move vertically downward through the foot pedal 7, drives the force-receiving disc 11 and the spring column 12 to move vertically downward through the lower pressure sleeve 6, so that the valve stem 9 and the valve core 14 move vertically downward, controls and opens the infusion volume of the valve body 1, and docks the pipe fittings through the flange plates 2 on both sides, so that the liquid is directly injected into the valve body 1 to complete the transfer of the liquid;

[0031] Step 3: When it is necessary to completely close the valve body 1, the threaded rod 5 can be directly separated from the rubber cover 3, and then the foot directly steps on the foot pedal 7. The valve core 14 directly contacts the bottom end of the valve body 1 vertically, seals the inside of the valve body 1 through the valve core 14 and the gasket 13, and then vertically positions and locks the foot pedal 7 and the valve body 1 through the threaded rod 5 to prevent the spring column 12 from pushing the force-receiving disc 11 in the reverse direction, so that the force-receiving disc 11 drives the foot pedal 7 to move vertically upward, improving the accuracy of opening or closing the valve body 1.

[0032] Therefore, the above-disclosed implementation schemes are illustrative in all aspects and not the only ones. All changes within the scope of the present utility model or within the scope equivalent to the present utility model are encompassed by the present utility model.
