DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, a double floating ball valve proposed by the utility model includes a valve body 1; two sets of filtering mechanisms are arranged on the valve body 1, and the two sets of filtering mechanisms are respectively arranged at the input end of the first sphere and between the first sphere and the second sphere, and the filtering mechanisms are used to intercept and filter impurities in the medium to avoid clogging of the sphere.

[0021] The filtering mechanism includes a filter seat 4, an interception frame 5 and a limit plate 404; channels 401 are provided at both ends of the filter seat 4, and the channels 401 are adapted to the valve body 1; the interception frame 5 is slidably connected to the inside of the filter seat 4, and a filter screen 501 is installed on the interception frame 5 and on the side away from the input end of the valve body 1, and a finger groove 502 is provided on the side wall of the interception frame 5, which is convenient for inserting fingers to slide the interception frame 5 along the inner wall of the filter seat 4 and remove it. The filter holes of the filter screens 501 in the two groups of filtering mechanisms are reduced successively, which is convenient for filtering impurities in the medium step by step; one end of the limit plate 404 is hingedly connected to the filter seat 4, and the other end is detachably connected to the filter seat 4, and the limit plate 404 is abutted against the interception frame 5.

[0022] Furthermore, mounting holes are evenly formed on the filter seat 4 and around the channel 401 , and the filter seat 4 is detachably connected to the valve body 1 through bolts and the mounting holes, so as to facilitate maintenance.

[0023] Furthermore, a connecting seat B407 is provided on the filter seat 4, a connecting seat A405 is provided at a corresponding position on the limiting plate 404, a screw rod 406 is threadedly connected to the connecting seat A405, and the other end of the screw rod 406 is threadedly connected to the connecting seat B407.

[0024] Furthermore, an elastic member 402 is installed on the inner wall of the filter seat 4 , and an abutment plate 403 is installed on the other end of the elastic member 402 . The abutment plate 403 is slidably connected to the inner wall of the filter seat 4 and abutted against the interception frame 5 .

[0025] Furthermore, a discharge pipe 408 is installed on the bottom end of a side wall of the filter seat 4 and close to the output end of the valve body 1, and the other end of the discharge pipe 408 is threadedly connected to a sealing seat 409.

[0026] In this embodiment, the valve body 1 is installed in a suitable position and put into use, and the first ball and the second ball are adjusted so that the medium channel is opened, and the medium first passes through the filter mechanism at the input end of the first ball, and the impurities in the medium are intercepted by the filter net 501 and stay between the interception frame 5 and the filter seat 4. The filtered medium passes through the first ball and moves to the second group of filter mechanisms to be filtered again. At this time, the intercepted impurities stay between the filter seat 4 and the interception frame 5 in the second group of filter mechanisms, and the medium after step-by-step filtration finally continues to flow along the second ball;

[0027] After using it for a period of time, the first sphere and the second sphere are adjusted to close the medium channel, and the sealing seat 409 is rotated to separate it from the discharge pipe 408, so that the medium intercepted between the filter seat 4 and the interception frame 5 can be discharged first, so that the limiting plate 404 can be opened to take out the interception frame 5 later, and the screw 406 is rotated to separate it from the connecting seat B407, and the limiting plate 404 can be rotated. The compressed elastic member 402 drives the abutment plate 403 to slide along the inner wall of the filter seat 4 under the action of elastic recovery, and then pushes the interception frame 5 toward the outside of the filter seat 4. The interception frame 5 can be pulled out along the inner wall of the filter seat 4 by inserting the finger into the finger groove 502, so as to assist the disassembly of the interception frame 5. After the interception frame 5 is pulled out, the impurities in the medium are intercepted in the interception frame 5, and the impurities in the interception frame 5 can be cleaned.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 2 As shown, a double floating ball valve proposed by the utility model, compared with the first embodiment, is provided with two sets of mounting seats 101 at the top of the valve body 1, the valve stem 102 in the valve body 1 is rotatably connected with the corresponding mounting seats 101, and a driving mechanism is provided between the two sets of mounting seats 101, and the driving mechanism drives the two sets of valve stems 102 to rotate to automatically adjust the corresponding first sphere and second sphere.

[0030] Furthermore, the driving mechanism includes an installation box 2, an incomplete gear 3 and a driven tooth 301; the installation box 2 is connected between two groups of mounting seats 101, and a cover plate 201 is hingedly connected to the installation box 2, the cover plate 201 is set to be L-shaped, and the end of the cover plate 201 away from the hinged end is detachably connected to the installation box 2 by bolts; the incomplete gear 3 is driven to rotate by a micro motor installed inside the installation box 2; two groups of driven teeth 301 are provided, and the two groups of driven teeth 301 are respectively installed at the top of the corresponding valve stem 102, and the two groups of driven teeth 301 are respectively intermittently meshed with the incomplete gear 3.

[0031] In this embodiment, the incomplete gear 3 is driven to rotate by a micro motor. When a group of driven teeth 301 at the top of the valve stem 102 on the first sphere located at the input end of the valve body 1 is meshed and connected with the teeth on the incomplete gear 3, as the incomplete gear 3 continues to rotate, the first sphere can be driven to rotate to open the medium channel. The medium passes through the first sphere and flows to the second sphere. The incomplete gear 3 continues to rotate, and the teeth on it are meshed and connected with another group of driven teeth 301 corresponding to the second sphere, so that the second sphere can be rotated to continue to open the medium channel. At this time, the micro motor is turned off, and the medium can flow smoothly along the valve body 1. When it is necessary to close the medium channel, the incomplete gear 3 is started and driven by the micro motor to rotate in the opposite direction, and then it is first meshed and connected with the driven teeth 301 corresponding to the second sphere, and the second sphere is rotated to automatically close the medium channel, and then the first sphere is rotated to close the automatic medium channel. Compared with manual adjustment, the adjustment is convenient and quick, the degree of automation is high, and the adjustment error is reduced.

[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
