The fluid filtered by the filtering device 2 is converged into a discharging main pipe so as to be subjected to concentrated cooling and other treatments.

The exhaust pipelines 1 are divided into two groups, and valve core states of the valves 3 connected to the two groups of exhaust pipelines 1 are opposite; wherein the valve core state comprises the valve core gradually opening and the valve core gradually closing; the opposite state includes the valve element of one set of valves 3 being gradually opened and the valve element of the other set of valves 3 being gradually closed.

The sum of the angles between the central section of the perforated sphere, parallel to the orifice of the perforated sphere and coplanar to the section of the valve stem, of the two sets of ball valves and the section of the discharge duct 1 is 90 °.

When the orifice of the perforated sphere completely corresponds to the inlet and outlet of the valve body, the discharge pipeline 1 is opened, and the fluid throughput is 100%; when the orifice of the perforated sphere is completely staggered with the inlet and outlet of the valve body, the discharge pipeline 1 is closed, and the fluid throughput is 0%; when the orifice of the perforated sphere coincides with the inlet/outlet portion of the valve body, the discharge conduit 1 is opened, but the fluid throughput is between 0% and 100%.

When the valve 3 adopts a butterfly valve, the butterfly valve comprises a valve body, a butterfly plate and a valve rod, the valve core is the butterfly plate, the butterfly plate is rotatably arranged in the valve body, and the top end of the butterfly plate is connected with the valve rod; at this time, the sum of the included angles between the butterfly plates of the two groups of butterfly valves and the section of the discharge pipeline 1 where the butterfly plates are positioned is 90 degrees.

When the butterfly plate is parallel to the section of the discharge pipeline 1, namely when the included angle between the butterfly plate and the section of the discharge pipeline 1 is 0 DEG, the discharge pipeline 1 is closed; when the butterfly plate is perpendicular to the section of the discharge pipeline 1, namely when the included angle of the butterfly plate and the section of the discharge pipeline 1 is 90 degrees, the discharge pipeline 1 is completely opened, and the fluid throughput is 100%; when the butterfly plate makes an acute angle with the cross section of the discharge duct 1, the discharge duct 1 is open, but the fluid throughput is between 0% and 100%.

The linkage positioning structure 4 comprises at least one linkage piece 41 for connecting the valves 3 in series to form a control chain, two ends of the linkage piece 41 are respectively connected with valve rods of the two valves 3, and each linkage piece 41 is driven by a rotary piece 42 to drive the valve rods of the valves 3 in the control chain to rotate in the same direction. Specifically, when the rotating member 42 rotates, all valve stems of the valves 3 are driven to rotate by the linkage member 41, and as the valve core states of the two sets of valves 3 are opposite, the rotating member 42 can simultaneously drive the two sets of valves 3 to operate in opposite states, that is, when one set of valves 3 is opened, the other set of valves 3 is closed; when the opening angle of one group of valves 3 is 30 degrees, the opening angle of the other group of valves 3 is 60 degrees. Since the valve stem is typically threaded with the valve body, rotation of the rotary member 42 to any angle positions the valve spool.

The linkage 41 comprises a connecting rod 411 and a short arm 412; the two short arms 412 are arranged in parallel, one ends of the two short arms 412 are respectively connected with the valve rods of the two valves 3, the other ends of the two short arms 412 are rotatably connected with the two ends of the connecting rod 411, and the rotating piece 42 is connected with one of the short arms 412.

When it is desired to control one valve 3 alone, the pin can be removed, the connecting rod 411 can be removed, and the valve 3 can be controlled by rotating the valve stem only through the short arm 412. The detachable design has stronger universality and more convenient use.

Example 1

When the number of the discharge pipelines 1 in each group is one, the valves 3 (a first valve, a second valve; corresponding to a first valve core and a second valve core) on the two discharge pipelines 1 are driven by one linkage positioning structure 4, and the linkage positioning structure 4 comprises a linkage piece 41 and a rotary piece 42, as shown in figures 3-4; the specific control principle is as follows:

the two ends of the connecting rod 411 of the linkage piece 41 are connected with the valve rods of the two valves 3 through the short arms 412 and the hinge piece 413, so that when the rotary piece 42 is rotated, the rotary piece 42 can drive one of the short arms 412 to rotate, the short arm 412 drives the other short arm 412 to rotate in the same direction through the connecting rod 411, the two short arms 412 rotate in the same direction, the valve rods of the two valves 3 can be respectively driven to rotate in the same direction, and then the two valve cores are driven to rotate in the same direction;

and because the first valve core and the second valve core are opposite in state, for example, the opening angle of the first valve core is a, the opening angle of the second valve core is b, and a+b=90°.

When a is 0 DEG, b is 90 DEG, the corresponding discharge pipe 1 of the valve I is closed, and the corresponding discharge pipe 1 of the valve II is opened. That is, when one of the discharge pipes 1 is clogged with the filter device 2 connected thereto, the discharge pipe 1 may be closed by the forward or reverse rotation of the rotary member 42 while the other discharge pipe 1 is opened, at which time the filter material in the clogged filter device 2 may be replaced without stopping;

when a is 0-90 DEG, b is 90-0 DEG; for example: when a is 30 degrees, b is 60 degrees, and at the moment, both the two discharge pipelines 1 are opened, and the flow of the discharge pipeline 1 corresponding to the first valve is smaller than that of the discharge pipeline 1 corresponding to the second valve. The condition is suitable for one filter device 2 to be slightly blocked, and the other filter device 2 is started to share the filtering pressure for the blocked filter device 2, so that stable and efficient filtering of fluid is ensured.

The scheme can realize one-key switching operation and simultaneous operation of two groups of discharge pipelines 1, and is rapid in operation, time-saving, labor-saving, safe and practical.

Example 2

When the number of the discharge pipelines 1 in one group is set as one, the number of the discharge pipelines 1 in the other group is set as two, the valves 3 (a valve I, a valve II and a valve III; corresponding valve core I, valve core II and valve core III) on the three discharge pipelines 1 are driven by one linkage positioning structure 4, and the linkage positioning structure 4 comprises two linkage parts 41 and one rotating part 42, as shown in figure 5; the specific control principle is as follows:

the three valves 3 are connected in series by two linkages 41: two ends of the connecting rod 411 of one linkage piece 41 are connected with the valve rods of the valve I and the valve II through a short arm 412 and a hinge piece 413, and two ends of the connecting rod 411 of the other linkage piece 41 are connected with the valve rods of the valve II and the valve III through the short arm 412 and the hinge piece 413. The swivel member 42 is connected to one of the short arms 412.

Thus, when the rotary member 42 is rotated, the rotary member 42 can drive one of the short arms 412 to rotate, the other short arm 412 is driven to rotate in the same direction by the connecting rod 411 by the short arm 412, the third short arm 412 is driven to rotate in the same direction by the other connecting rod 411, the valve rods of the three valves 3 can be driven to rotate in the same direction by the three short arms 412, and then the three valve cores are driven to rotate in the same direction.

When the first valve is a group, the second valve and the third valve are a group, the opening angle of the first valve core is a, the opening angles of the second valve core and the third valve core are b, and a+b=90°.

When a is 0 DEG, b is 90 DEG, the discharge pipe 1 corresponding to the valve I is closed, and the discharge pipes 1 corresponding to the valve II and the valve III are opened. That is, when the filtering apparatus 2 to which one set of the discharge pipes 1 is connected is clogged, the set of the discharge pipes 1 may be closed by the forward or reverse rotation of the rotary member 42 while the other set of the discharge pipes 1 is opened, at which time the filter material in the clogged filtering apparatus 2 may be replaced without stopping; in the case of an increased flow, it is also possible to switch from a single discharge conduit 1 to two discharge conduits 1, achieving an efficient filtration process.

When a is 0-90 DEG, b is 90-0 DEG; for example: when a is 30 degrees, b is 60 degrees, and at the moment, all three discharge pipelines 1 are opened, and the flow of the discharge pipeline 1 corresponding to the valve I is smaller than the flow of the discharge pipeline 1 corresponding to the valve II and the valve III. This kind of condition is applicable to some filtration equipment 2 slightly to block up, opens other filtration equipment 2 and shares the filtration pressure for the filtration equipment 2 that blocks up, guarantees that fluid is stable, high-efficient filtration.

Example 3

When the number of the two groups of the discharge pipelines 1 is two or more, the valves 3 on the two groups of the discharge pipelines 1 can be driven by at least one linkage positioning structure 4;

for example: when the number of the two groups of the discharge pipelines 1 is two (a first valve, a second valve, a third valve and a fourth valve; corresponding to the first valve core, the second valve core, the third valve core and the fourth valve core), the four discharge pipelines 1 can be driven by one linkage positioning structure 4, and the linkage positioning structure 4 comprises three linkage pieces 41 and one rotating piece 42, as shown in fig. 6;

the four valves 3 are connected in series by three linkages 41: two ends of a connecting rod 411 of one linkage member 41 are connected with valve rods of a first valve and a second valve through a short arm 412 and a hinge member 413, two ends of the connecting rod 411 of the other linkage member 41 are connected with valve rods of the second valve and the third valve through the short arm 412 and the hinge member 413, and two ends of the connecting rod 411 of the last linkage member 41 are connected with valve rods of the third valve and the fourth valve through the short arm 412 and the hinge member 413. The swivel member 42 is connected to one of the short arms 412.

Thus, when the rotary member 42 is rotated, the rotary member 42 can drive one of the short arms 412 to rotate, and the short arm 412 drives all the short arms 412 to rotate in the same direction through the connecting rod 411, so as to drive the valve rods of the four valves 3 to rotate in the same direction, namely, drive the three valve cores to rotate in the same direction.

When the first valve and the second valve are in a group, the third valve and the fourth valve are in a group, the opening angles of the first valve core and the second valve core are both a, the opening angles of the third valve core and the fourth valve core are both b, and a+b=90 degrees.

When a is 0 DEG, b is 90 DEG, the discharge pipe 1 corresponding to the valve I and the valve II is closed, and the discharge pipe 1 corresponding to the valve III and the valve IV is opened. That is, when the filtering apparatus 2 to which one set of the discharge pipes 1 is connected is clogged, the set of the discharge pipes 1 may be closed by the forward or reverse rotation of the rotary member 42 while the other set of the discharge pipes 1 is opened, at which time the filter material in the clogged filtering apparatus 2 may be replaced without stopping;

when a is 0-90 DEG, b is 90-0 DEG; for example: when a is 30 degrees, b is 60 degrees, at the moment, the four discharge pipelines 1 are all opened, and at the moment, the flow of the discharge pipeline 1 corresponding to the valve I and the valve II is smaller than the flow of the discharge pipeline 1 corresponding to the valve III and the valve IV. This kind of condition is applicable to some filtration equipment 2 slightly to block up, opens other filtration equipment 2 and shares the filtration pressure for the filtration equipment 2 that blocks up, guarantees that fluid is stable, high-efficient filtration.

In addition, four discharge pipes 1 may be driven by two of the interlocking positioning structures 4, that is, each interlocking positioning structure 4 includes one interlocking member 41 and one rotating member 42 (not shown in the drawings, the principle is the same as that of example 1).

When the discharge pipes 1 are divided into two or more groups, as in the above-described embodiment 1, the valve bodies of the valves 3 connected to at least two groups of the discharge pipes 1 are opposite in state.

For the case that the valve core states of the valves 3 connected to one or more groups of the exhaust pipes 1 are the same, the valve cores of the valves 3 connected to each group of the exhaust pipes 1 are driven by at least one linkage positioning structure 4, so that the valves 3 on at least one group of the exhaust pipes 1 can be driven to be opened or closed by the rotation of one rotating member 42, the valve core structure is applicable to the case that a plurality of exhaust pipes 1 are simultaneously controlled, the valves 3 do not need to be opened or closed one by one, and the valve core structure is time-saving and labor-saving, is fast in adjustment, and is shown in fig. 7.

The above embodiments are provided to illustrate the technical concept and features of the present utility model and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model.
