Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1-2, in an embodiment of the present invention, a flange type faucet ball valve includes a valve body 1, a valve cavity 2 is disposed inside the valve body 1, a valve ball 3 and a valve plate 10 are disposed in the valve cavity 2, a circular hole 4 penetrating through the valve ball 3 is disposed in the center of the valve ball 3, a filter screen 5 is disposed in the circular hole 4, a first valve rod 6 is fixedly connected to the top of the valve ball 3, the first valve rod 6 is of a hollow structure, a through hole is disposed in the center, a through hole is disposed on the upper portion of the valve ball 3, the upper end of the through hole on the upper portion of the valve ball 3 is communicated with the bottom end of the through hole of the first valve rod; the top of the first valve rod 6 is connected with a water inlet pipe through a joint;

the valve plate 10 is arranged on the left side of the valve ball 3, and the top of the valve plate 10 is fixedly connected with a second valve rod 7;

the bottom of the valve body 1 is provided with a water outlet 8, and the water outlet 8 is communicated with the valve cavity 2 between the valve plate 10 and the valve ball 3.

Further, the filter net 5 is located at the left side of the through hole of the upper portion of the valve ball 3. So that the sewage can be flushed to the left side of the filter screen 5 when the filter screen 5 is flushed by the water flow.

Further, filter screen 5 links firmly valve ball 3, and this filter screen 5 can be fixed in circular frame's inside earlier, and then circular frame links firmly with valve ball 3.

Further, a seal ring is provided on the outer periphery of the valve plate 10.

Further, the joint at the top of the first valve rod 6 may be a common joint or a rotary joint (since the rotation angle of the first valve rod 6 is within 90 °, various connection joints may be adopted). In particular, as far as the connection of the joint is prior art, the hollow first valve stem 6 is substantially identical to a common pipe when the joint is connected.

Further, the water outlet 8 is connected with a water discharge pipe through a joint, and a valve is arranged on the water discharge pipe. The valve controls the drainage switch.

Further, a first valve seat 9 matched with the valve ball 3 is arranged in the valve cavity 2 on the right side of the valve ball 3, and a second valve seat matched with the valve plate 10 is arranged in the valve cavity 2. The blocking function of the valve plate 10 for the passage is improved.

Further, first valve rod 6 and second valve rod 7 all link firmly the hand wheel, also can connect electric actuator. The rotation can be more convenient through the hand wheel.

Further, flanges for connection are provided at both ends of the valve body 1.

The invention has the structural characteristics and the working principle that: firstly, when the valve is used, the flow direction is required to be from left to right, the first valve rod 6 drives the valve ball 3 to rotate to realize opening and closing of a channel, the second valve rod 7 drives the valve plate 10 to rotate to realize opening and closing (normally open) of the channel, and fluid can be filtered by the filter screen 5 when passing through the circular hole 4 of the valve ball 3; after using a period, rotatory second valve stem 7 closes the passageway, rotatory first valve stem 6 makes round hole 4 of valve ball 3 rotatory to the level, then supply water through the inlet tube, rivers get into in the round hole 4 of valve ball 3 by the through-hole of first valve stem 6 and valve ball 3, and produce the washing effect to filter screen 5, adnexed debris follow rivers and get into the space between valve plate 10 and the valve ball 3 on the filter screen 5, then open the valve on the outlet 8 this moment and make sewage flow from the drain pipe, wash the rotatory passageway of opening of valve plate 10 after a period, the valve closure on the drain pipe, resume normal use. Due to the particularity of the position of the filter screen 5, the backflushing mode is adopted to wash the filter screen 5, so that the service life of the filter screen 5 can be greatly prolonged, the maintenance period is shortened, the cost is greatly reduced, and the device is worthy of being widely popularized.

Example two

Referring to fig. 3, in order to avoid the problem that the impact force on the filter screen 5 is small due to the fact that the water flow is parallel to the filter screen 5 when entering the valve ball 3, a stopper 21 is disposed at the top of the circular hole 4 of the valve ball 3, the top of the stopper 21 is fixedly connected to the valve ball 3 and is located on the right side of the through hole at the upper portion of the valve ball 3, and the lower end of the stopper 21 extends to the lower portion of the through hole at the upper portion of the valve ball 3. When water flows into the circular hole 4 through the through hole, the flow direction is changed by the block 21, and the water flow is inclined leftwards, so that the filter screen 5 can be completely washed.

Further, the cross section of the stopper 21 is triangular, and the left side is an inclined surface.
