Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 4, 7 and 8, the present invention provides a double control valve, which includes a valve body 2, a magnetic element, a switch assembly and a locking member 10, wherein a valve seat 3 and a sealing ball 4 placed on the valve seat 3 are disposed inside the valve body 2, one end of the valve body 2 is connected to a valve cover 5, and the valve body 2 is provided with a first counter bore 21 and a second counter bore 22 which are arranged at an interval and used for accommodating the magnetic element 1, so as to realize switching between a locking state and an unlocking state, the depth of the first counter bore 21 is smaller than the thickness of the magnetic element 1, and the depth of the second counter bore 22 is greater than or equal to the thickness of the magnetic element 1;

the switch assembly is arranged on the valve body 2 and is positioned on one side of the valve body 2, which is provided with a first counter bore 21 and a second counter bore 22, the switch assembly comprises a valve rod 6 and a handle 7, the valve rod 6 is arranged inside the valve body 2, one end of the valve rod 6 is connected with the sealing ball 4, the other end of the valve rod is connected with the handle 7, the handle 7 adopts a manual handle or an electric handle, and the valve rod 6 is driven to rotate by the handle 7 during working so as to drive the sealing ball 4 to rotate, thereby realizing the control of the opening and closing of the double-control valve; meanwhile, a third counter bore 71 is formed below the handle 7, and the depth of the third counter bore 71 is greater than or equal to the thickness of the magnetic element 1;

a groove is arranged below the locking piece 10 and is used for being matched and connected with the second boss 72 above the handle 7 when the locking state is adjusted so as to drive the handle 7 to rotate; the locking piece 10 has magnetism, and can suck the magnetic element 1 into the third counter bore 71 and adjust the position of the magnetic element 1 relative to the valve body 2 through rotation so as to transfer the magnetic element 1 into the first counter bore 21 or the second counter bore 22, thereby controlling the locking and unlocking of the double-control valve;

when the valve is in a locking state, the magnetic element 1 is positioned between the first counter bore 21 and the third counter bore 71, the handle 7 is clamped to further limit rotation, and free opening and closing cannot be carried out; when the valve is in an unlocked state, the magnetic element 1 is positioned inside the second counter bore 22, and the handle 7 can rotate freely and can be opened and closed freely, so that double control of the valve is realized.

Further, the magnetic elements 1, the first counter bores 21, the second counter bores 22 and the third counter bores 71 are equal in number, and are respectively 2-6. When the number of the magnetic elements 1 is two, the first counter bore 21 and the second counter bore 22 are arranged at an interval of 90 degrees, and the locking piece 10 rotates 90 degrees when being locked or unlocked. The adjacent magnetic elements 1 have different magnetic poles on the same plane, when the number of the magnetic elements 1 is two, the N-level of the left magnetic element 1 faces the handle 7, the S-level faces the valve body 2, the S-level of the right magnetic element 1 faces the handle 7, and the N-level faces the valve body 2, so that the valve can be effectively prevented from being opened randomly.

Further, a first boss 23 is arranged above the valve body 2, and an indication mark 24 is arranged on the first boss 23 and used for indicating the opening and closing state of the double control valve. Meanwhile, the lengths of the left side and the right side of the handle 7 are different, and the long side is used for covering the indicating mark 24 so as to realize state indication; or the width of the left side and the width of the right side of the handle 7 are different, and the indicating mark 24 is covered by the wide side when the handle is used, so that the state indication is realized.

Further, the diameters of the first counterbore 21, the second counterbore 22 and the third counterbore 71 are larger than or equal to the diameter of the magnetic element 1, so that the magnetic element 1 can smoothly enter the counterbores, and better operability is achieved; meanwhile, the depth of the first counter bore 21 is 1/3-1/2 of the thickness of the magnetic element 1, so that the valve can be in a stable locking state, and the valve has the advantage of reliable locking.

The specific method of use of the present invention is described in further detail below. As shown in fig. 5, when the double control valve is in a locked and closed state, the central line of the handle 7 is perpendicular to the central axis of the double control valve by 90 °, the "off" shape on the boss 23 on the valve body 2 can be seen, and at this time, 1/3 to 1/2 of the magnetic element 1 are in the first counterbore 21 of the valve body 2, and the other 1/2 to 2/3 of the magnetic element 1 are in the third counterbore 71 of the handle 7, so that the handle 7 is locked and can not rotate. If the valve needs to be rotated, the locking piece 10 is placed above the handle 7, so that the magnetic element 1 is completely sucked into the third counter bore 71, the valve is opened after the valve is rotated 90 degrees anticlockwise, the locking piece 10 is taken away, the magnetic element 1 completely falls into the second counter bore 22 of the valve body, and the valve is in an unlocked and opened state and can be freely opened and closed. As shown in fig. 6, when the double control valve is in the unlocked and opened state, the central line of the handle 7 is parallel to the central axis of the double control valve, the second boss 72 on one side of the handle 7 is also parallel to the central axis of the double control valve, and the long side or the thick side of the handle 7 completely covers the word "off", thereby realizing the state indication of the valve.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
