Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of backflow valves, in particular to an automatic control backflow valve with switchable bypass. BACKGROUND

[0002] A safety backflow valve is a valve that protects the system from being damaged due to excessive pressure. Once the pressure of the medium in the system pipeline or device exceeds the set value, it will automatically release the pressure to achieve the purpose of safety protection. Safety backflow valves are divided into two categories: spring type and rod type. In addition, there are impulse type safety valves, pilot type safety valves, safety switching valves, safety pressure relief valves, and static weight type safety valves.

[0003] Most existing backflow valves have the advantage of being structurally strong, but the existing backflow valves usually only have one bypass and cannot be customized or replaced, resulting in a single type of backflow valve being limited in use and unable to adapt to more working environments. Therefore, an automatic control backflow valve with switchable bypass is proposed to solve the above problems. SUMMARY

[0004] (I) Technical problems solved

[0005] In view of the deficiencies of the prior art, the present application provides an automatic control backflow valve with switchable bypass, which has the advantage of being able to conveniently detect the bypass flow rate, solving the problem that most existing backflow valves have the advantage of being structurally strong, but the existing backflow valves usually only have one bypass and cannot be customized or replaced, resulting in a single type of backflow valve being limited in use and unable to adapt to more working environments.

[0006] (II) Technical solutions

[0007] The technical scheme for solving the above technical problems is as follows: an automatic control backflow valve of bypass switchable collocation, comprising a valve body, bypass holes are arranged on the left and right sides of the valve body, a first bypass pipe is fixedly connected to the right side of the valve body through a flange and is in communication with the bypass hole on the right side, a connecting groove is arranged on the left side of the valve body outside the bypass hole on the left side, an installation groove is arranged in the valve body and is in communication with the bypass hole on the left side and is located on the right side of the connecting groove, a connecting frame extending into the bypass hole is fixedly installed on the top wall in the installation groove, a rotating frame is rotatably connected to the inner side of the connecting frame, a cutoff switch is fixedly installed on the outer side of the rotating frame on the side wall in the installation groove, a leakage plate is fixedly installed in the bypass hole on the left side, a second bypass pipe is fixedly connected to the left side of the valve body through a flange and is in communication with the bypass hole on the left side, a trigger rod extending into the connecting groove is fixedly installed on the right side of the second bypass pipe, a positioning rod is fixedly installed on the top of the second bypass pipe, a limiting sleeve extending to the outside of the positioning rod is fixedly installed on the left side of the valve body, and a processor is fixedly installed on the left side of the valve body above the limiting sleeve and is electrically connected with the cutoff switch.

[0008] The beneficial effects of the present application are as follows:

[0010] 2) The automatic control backflow valve of bypass switchable collocation has the advantage that the bypass can be conveniently intelligently identified.

[0011] On the basis of the above technical scheme, the present application can also be improved as follows.

[0012] Further, a check valve assembly is arranged in the first bypass pipe, the valve body and the liquid outlet amount on the top have a linear proportional relationship with the liquid outlet amounts of the first bypass pipe and the second bypass pipe, a water flow groove is arranged on the top of the leakage plate, and the rotating frame extends into the water flow groove.

[0013] The beneficial effects of the above further scheme are that the leakage plate can control the direction of water flow, so that the water flow can conveniently drive the rotating frame to rotate.

[0014] Further, a trigger piece is fixedly installed on the outer side of the rotating frame, and the cutoff switch is in the shape of C and the trigger piece passes through the inner side of the cutoff switch when rotating.

[0015] The beneficial effects of the above further scheme are that the cutoff switch can conveniently determine the current flow rate through the trigger frequency of the trigger piece.

[0016] Furthermore, the trigger rod is arranged in two sections, left and right. The trigger rod at the left end is a fiberglass rod, and the trigger rod at the right end is a copper rod with the right side being truncated cone-shaped.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the trigger rod with this configuration can prevent current from being conducted to the left, while the right side has good conductivity, making it easy to conduct on the right side.

[0019] The advantage of adopting the above-mentioned further solution is that the configuration of the connection component can identify the type of bypass by the current when the trigger rod is inserted, and the bypass flow rate can also be monitored.

[0020] Furthermore, both the first connecting piece and the second connecting piece are open annular, both the first connecting piece and the second connecting piece are copper sheets, and a buffer elastic pad is fixedly provided between the connection between the first connecting piece and the mounting groove.

[0021] The advantage of adopting the above-mentioned further solution is that the open-type connecting piece can prevent the current from forming a short circuit at the first or second connecting piece.

[0024] Furthermore, the second bypass tube includes multiple manual secondary manual bypasses, each with a different fixed trigger rod position on the right side. The number of secondary manual bypasses is consistent with the number of contact holes, and the trigger rod always corresponds to the position of the contact hole.

[0025] The advantage of adopting the above-mentioned further solution is that this arrangement allows the positioning rod to always be inserted into the contact hole, facilitating connection. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-9 :

[0038] Example 1: An automatic control reflux valve with switchable bypass. The invention includes a valve body 1, with bypass holes 2 on both the left and right sides. A first bypass pipe 3, communicating with the right bypass hole 2, is fixedly connected to the right side of the valve body 1 via a flange. A connecting groove 4 is provided on the left side of the valve body 1 outside the left bypass hole 2. An installation groove 5, communicating with the left bypass hole 2 and located to the right of the connecting groove 4, is provided inside the valve body 1. A connecting frame 6, extending into the bypass hole 2, is fixedly installed on the top wall of the installation groove 5. A rotating frame 7 is rotatably connected to the inner side of the connecting frame 6. A shut-off switch 8 located outside the rotating frame 7 is fixedly installed on the inner wall. A leak plate 9 is fixedly installed inside the left bypass hole 2. A second bypass pipe 11 communicating with the left bypass hole 2 is fixedly connected to the left side of the valve body 1 via a flange. A trigger rod 12 extending into the connecting groove 4 is fixedly installed on the right side of the second bypass pipe 11. A positioning rod 13 is fixedly installed on the top of the second bypass pipe 11. A limiting sleeve 14 extending outside the positioning rod 13 is fixedly installed on the left side of the valve body 1. A processor 15 located above the limiting sleeve 14 and electrically connected to the shut-off switch 8 is fixedly installed on the left side of the valve body 1.

[0039] Furthermore, a check valve assembly is provided inside the first bypass pipe 3, and the liquid output of the valve body 1 and the top liquid output have a linear proportional relationship with the liquid output of the first bypass pipe 3 and the second bypass pipe 11; a water flow groove is provided on the top of the leak plate 9, and the rotating frame 7 extends into the water flow groove.

[0040] The beneficial effect of adopting the above-mentioned further solution is that the perforated plate 9 can control the direction of water flow, so that the water flow can easily drive the rotating frame 7 to rotate.

[0041] Furthermore, a trigger plate is fixedly installed on the outside of the rotating frame 7, and the interrupting switch 8 is C-shaped and passes through the inside of the interrupting switch 8 when the trigger plate rotates.

[0042] The advantage of adopting the above-mentioned further solution is that this arrangement allows the interruption switch 8 to conveniently determine the current flow rate by the triggering frequency of the trigger plate.

[0043] Furthermore, the trigger rod 12 is arranged in two sections, left and right. The trigger rod 12 at the left end is a fiberglass rod, and the trigger rod 12 at the right end is a copper rod with the right side being truncated cone-shaped.

[0044] The beneficial effect of adopting the above-mentioned further solution is that the trigger rod 12 with this configuration can prevent current from being conducted to the left, while the right side has good conductivity, making it easy to conduct on the right side.

[0045] With the above settings, when the water flows through the valve body 1, it can flow out through the bypass holes 2 on the left and right sides. The first bypass pipe 3 has the effect of preventing backflow. When the water flows out through the left bypass, the flow rate of the water flowing out from the left side can be conveniently detected.

[0046] In Embodiment 2, based on Embodiment 1, a connecting assembly 10 electrically connected to the trip switch 8 is provided inside the connecting groove 4. The connecting assembly 10 includes a first connecting piece 101 fixed to the right inner wall of the connecting groove 4 and electrically connected to the trip switch 8. A conductive post 102 is fixedly installed on the left side of the first connecting piece 101. A sliding frame 103 located to the left of the conductive post 102 is fixedly installed inside the connecting groove 4. A second connecting piece 104 is slidably connected to the inner side of the sliding frame 103. An elastic pull rope 105 fixedly connected to the inner wall of the connecting groove 4 is fixedly installed on the left side of the second connecting piece 104. A contact hole 106 is opened inside the second connecting piece 104. A current transformer 107 sleeved on the outside of the conductive post 102 is fixedly installed inside the connecting groove 4.

[0047] The beneficial effect of adopting the above-mentioned further solution is that the configuration of the connection component 10 can be used to know what kind of bypass it is through the current when the trigger rod 12 is inserted, and the bypass flow rate can also be monitored.

[0048] Furthermore, both the first connecting piece 101 and the second connecting piece 104 are open annular shapes, both the first connecting piece 101 and the second connecting piece 104 are copper sheets, and a buffer elastic pad is fixedly provided between the connection between the first connecting piece 101 and the mounting groove 5.

[0049] The advantage of adopting the above-mentioned further solution is that the open-type connecting piece can prevent the current from forming a short circuit at the first connecting piece 101 or the second connecting piece 104.

[0050] Furthermore, there are several contact holes 106, and the number of conductive posts 102 is the same as the number of contact holes 106 and their positions correspond.

[0051] The advantage of adopting the above-mentioned further solution is that the arrangement of multiple contact holes 106 facilitates circuit connection at multiple locations.

[0052] Furthermore, the second bypass pipe 11 includes multiple manual secondary manual bypasses, and the positions of the trigger rod 12 fixed on the right side of each secondary manual bypass are different. The number of secondary manual bypasses is consistent with the number of contact holes 106, and the trigger rod 12 always corresponds to the position of the contact hole 106.

[0053] The advantage of adopting the above-mentioned further solution is that this arrangement allows the trigger rod 12 to always be inserted into the contact hole 106, which facilitates connection.

[0054] With the above settings, the multiple replaceable second bypass pipes 11 can enable the bypass to have a variety of application effects. At the same time, when the secondary bypass is replaced, the valve body 1 can automatically identify the current bypass type and automatically display the water flow rate.

[0055] Implementation steps for the first innovation point:

[0056] Step 1: The inserted trigger rod 12 can connect the first connecting piece 101 and the second connecting piece 104. At this time, the processor 15, the first connecting piece 101, the conductive post 102, the second connecting piece 104 and the shut-off switch 8 can form a circuit, thereby enabling the monitoring of the rotation of the rotating frame 7.

[0057] Step 2: When the water flows through the left bypass hole 2, due to the obstruction of the leak plate 9, the water can only pass through the water flow channel at the top, which can then drive the rotating frame 7 to rotate. At this time, the processor 15 receives the signal and can estimate and display the water flow speed.

[0058] Implementation steps for the second innovation point:

[0059] Step 1: When the secondary bypass is replaced, the positioning rod 13 and the limiting sleeve 14 can restrict the currently replaced second bypass tube 11, so that the trigger rod 12 on the right side can make correct contact. Since the secondary bypass is changed, the position of the trigger rod 12 on the right side changes, and the current passage position changes from the original conductive post 102 to another conductive post 102.

[0060] Step 2: When the location through which the current flows changes, the current transformer 107 detects the change in current and can then display the corresponding secondary bypass through the processor 15, thereby achieving intelligent identification of the currently installed bypass without affecting the speed monitoring of the first innovation point.
