In the present embodiment, the valve body 110 is cylindrical, and has a flared funnel opening 111 at the top of the valve body 110. Of course, the valve body 110 may have other shapes such as a rectangular tube shape, and is not particularly limited herein.
In the present embodiment, the pilot spool 150 is made of a light material, such as rubber, and the like, while its density is smaller than that of water, or is made of a heavy material, hollow, and its total weight is smaller than that of the same volume of water, and the pilot spool 150 can be lifted up under the buoyancy of water.
The funnel opening 111 is further integrally provided with a sealing snap ring, the first anti-fouling cover 170 is covered on the sealing snap ring and forms a pilot cavity with the sealing snap ring, the plugging seat 131 is accommodated in the pilot cavity, a plurality of first water inlets are formed in the first anti-fouling cover 170, and the first water inlets are communicated with the pilot cavity.

In the present embodiment, the water through holes 113 are plural, the plural water through holes 113 are uniformly arranged on the outer peripheral wall of the valve body 110 in a ring, and the water through holes 113 are arranged in the middle of the valve body 110 and close to the funnel opening 111. Specifically, the number of the water through holes 113 is six, and the six water through holes 113 are uniformly provided on the outer circumferential surface of the valve body 110. Each of the water passing holes 113 has an oval shape.
Referring to fig. 5, in the present embodiment, a water leakage hole 117 is formed at the bottom of the valve body 110, and the flow area of the water leakage hole 117 is smaller than that of the pilot through hole 151. In the pilot opening stage of the gravity closed floor drain 100 with the secondary opening, since the flow area of the water leakage hole 117 is smaller than that of the pilot through hole 151, the amount of water flowing from the pilot through hole 151 to the bottom of the valve body 110 is larger than that flowing from the bottom of the valve body 110, and the water flow can be gathered at the bottom of the valve body 110, so that buoyancy is provided for the bottom of the main valve element 130, and after the water is discharged, the water flow gathered at the bottom of the valve body 110 can flow out through the water leakage hole 117, so that the main valve element 130 descends under the action of gravity, the top of the main valve element 130 is plugged on the funnel opening 111 again, and the sealing effect is ensured.
Referring to fig. 6, the main valve core 130 includes a blocking seat 131, a connecting rod 133 and a floating head 135, the lower end surface of the blocking portion has an annular conical surface 137 for abutting on the funnel opening 111, one end of the connecting rod 133 is connected with the blocking seat 131, the other end of the connecting rod 133 is connected with the floating head 135, and the floating head 135 is accommodated at the bottom of the valve body 110 and can move upwards under the buoyancy.
In this embodiment, floating head 135 has buoyancy chamber 139 therein. The floating head 135 is a buoyancy ball structure, and the maximum buoyancy provided by the floating head is greater than the gravity of the whole main valve core 130, so that the plugging seat 131 can be driven by the connecting rod 133, and the annular conical surface 137 is separated from the funnel opening 111.
In other preferred embodiments of the present invention, the floating head 135 may also be made of a lightweight material, as will not be described herein.
In this embodiment, the pilot through hole 151 penetrates the plugging base 131, and the connecting rod 133 is fixedly connected to the bottom center of the plugging base 131. Specifically, the top end of the pilot through hole 151 is disposed at the center of the plugging seat 131, and the bottom end of the pilot through hole 151 is penetrated by the side portion of the plugging seat 131 near the center. During the pilot opening phase, water in the pilot cavity can collect through the pilot passage into the bottom of the valve body 110.
In summary, the working principle of the gravity closed floor drain 100 with the secondary opening provided by the invention is as follows: when no water exists, the device utilizes the gravity generated by the self weight of the main valve core 130 to enable the main valve core 130 to descend, the annular conical surface 137 at the bottom of the plugging seat 131 is pressed on the funnel opening 111 on the valve body 110 under the action of the gravity, no water exists at the bottom of the valve body 110, the main valve core 130 seals the funnel opening 111, meanwhile, the pilot valve core 150 seals the pilot through hole 151 under the action of the gravity generated by the self weight, and the pilot inner cavity and the interior of the valve body 110 are isolated from each other.
When the water flow reaches the local leakage of the device, the pilot valve core 150 is gradually immersed in water along with the increase of the water flow, the buoyancy of the water discharged by the pilot valve core 150 is also increased along with the gradual increase of the volume of the pilot valve core 150 immersed in water, when the buoyancy is larger than the gravity of the pilot valve core 150, the buoyancy and the gravity difference enable the pilot valve core 150 to rise and separate from the pilot through hole 151, so that the pilot through hole 151 is opened, and the water flow reaches the bottom of the valve body 110 along the pilot channel. When the flow rate of the water flow is greater than the leakage port flow rate at the bottom of the valve body 110, the water flow gradually fills the bottom of the valve body 110.
As the water flow gradually fills the bottom of the valve body 110, the floating head 135 at the lower part of the main valve core 130 is gradually immersed in water, as the volume of the floating head 135 immersed in water gradually increases, the buoyancy of the water discharged by the floating head 135 also increases, when the buoyancy is greater than the whole self gravity of the main valve core 130, the buoyancy and gravity difference make the floating head 135 drive the connecting rod 133 and the plugging seat 131 to rise, the annular conical surface 137 at the lower part of the plugging seat 131 separate from the funnel opening 111, so that the funnel opening 111 is opened, and the water flow passes through the funnel opening 111, enters the valve body 110 and enters the drainage pipeline through the water through hole 113, which is the opening state of the main valve core 130. As long as the flow rate of water is greater than the flow rate of the leakage port at the bottom of the valve body 110, the water level at the bottom of the valve body 110 can be kept constant, and the buoyancy generated by the water discharge of the main valve core 130 in the bottom of the valve body 110 can be kept constant, so that the main valve core 130 can be kept at the maximum opening degree all the time.
When the water flow stops, as a water leakage hole 117 is formed in the bottom of the valve body 110, the water flow gathered in the bottom of the valve body 110 gradually decreases, the immersed volume of the floating head 135 gradually decreases until no water is discharged, the buoyancy generated by water discharge gradually decreases to no water, the main valve core 130 is lowered under the action of self gravity, the annular conical surface 137 at the bottom of the plugging seat 131 is pressed on the funnel opening 111, so that the pilot cavity and the interior of the valve body 110 are isolated from each other again, and the initial gravity self-sealing state of the main valve core 130 is returned.
