[0036] like Figure 1~Figure 4 As shown, this embodiment proposes a one-to-two wire splitter for an emergency shut-off valve, comprising: a fixed rod 1 for installation on a valve body, the fixed rod 1 having a wire groove 101, the wire groove 101 being used to place the wire; a wire splitting box 2 is arranged at one end of the fixed rod 1 away from the valve body, the wire splitting box 2 having a wire splitting cavity 201, two symmetrically arranged wire splitting inlets 202 and two symmetrically arranged wire splitting outlets 203, the wire splitting inlets 202 and the wire splitting outlets 203 are both connected to the wire splitting cavity 201, and the wire splitting box 2 is used to split one wire into two wires.
[0037] Optionally, it also includes: there are two wire splitting wheels 3, the two wire splitting wheels 3 are rotatably arranged in the wire splitting cavity 201, and the two wire splitting wheels 3 are symmetrically arranged, and the wire passes through the wire splitting inlet 202, the wire splitting wheel 3 and the wire splitting outlet 203 in sequence.
[0038] In this embodiment, the fixed rod 1 with a wire groove 101 is the basic installation component of the splitter. The fixed rod 1 is set on the valve body. The design of the wire groove 101 cleverly provides a wire path so that the wire can slide smoothly without being damaged or twisted, ensuring the integrity of the wire.
[0039] The wire splitting box 2 is arranged at one end of the fixed rod 1 away from the valve body, and the wire splitting box 2 is provided with a wire splitting cavity 201, which is the core area of the wire splitting operation. Two symmetrically arranged wire splitting inlets 202 are arranged on the top of the wire splitting box 2, and wire splitting outlets 203 are symmetrically arranged on both sides of the wire splitting box 2, ensuring that the cables can be evenly and symmetrically distributed in two directions. At the same time, two wire splitting wheels 3 are rotatably arranged in the wire splitting cavity 201, and the two wire splitting wheels 3 are symmetrically arranged to ensure that the wires are evenly distributed and balanced during the wire splitting process. Each wire splitting wheel 3 is directly involved in the path of the wire, so that the wire can slide out smoothly from the wire splitting outlet 203 of the wire splitting box 2. The wire splitting process is as follows: the wire passes through the wire slot 101 on the fixed rod 1, and comes out from the end of the wire slot 101 away from the valve body. At this time, the operator can use manpower to split the wire into two strands, and then the operator makes the two strands of wire enter the wire splitting cavity 201 from the two wire splitting inlets 202 on the wire splitting box 2 respectively. The two strands of wire pass through the wire splitting inlet 202 and the wire splitting wheel 3 in turn, and finally the two strands of wire come out from the two wire splitting outlets 203 symmetrically arranged on the wire splitting box 2 respectively. The operator can pull any of the two wires to open or close the valve body by pulling the wire. When one wire breaks, the other wire can still control the opening and closing of the valve body normally. In this embodiment, the symmetrically arranged wire splitting wheel 3 ensures the symmetry of the wires on both sides and the consistency of the wire tension, reduces the displacement, and is crucial for the immediate response of the emergency shut-off valve.
[0040] Optionally, it further includes: there are two tensioning wheels 4, the two tensioning wheels 4 are respectively rotatable and slidably arranged between the two branching outlets 203 and the branching wheel 3, and the tensioning wheels 4 are used for tensioning the wire.
[0041] In this embodiment, a tensioning wheel 4 is provided between a branching outlet 203 and a branching wheel 3, and the tensioning wheel 4 directly acts on the wire to be output. When the operator pulls the wire output from the branching outlet 203 on the right side of the branching box 2, the tensioning wheel 4 on the right side is subjected to the downward pressure of the wire output from the right side, so that the tensioning wheel 4 on the right side slides downward, so that the wire can be smoothly pulled out from the branching outlet 203 on the right side, thereby driving the wire in the wire slot 101 to open or close the valve body by pulling. In this process, the tensioning wheel 4 on the left side of the branching box 2 loses the pressure from the wire, and the tensioning wheel 4 on the left side rises, pushing the wire on the left side upward, blocking the wire on the left side, and reducing the wire blockage at the branching outlet 203 on the left side.
[0042] Optionally, it also includes: there are two lifting brackets 5, the two lifting brackets 5 are respectively lifted and lowered in the line dividing cavity 201, the two lifting brackets 5 are respectively located between the two line dividing outlets 203 and the line dividing wheel 3, and a tensioning wheel 4 is rotatably arranged on each lifting bracket 5; there are two first elastic members 6, the two ends of the first elastic member 6 respectively act on the tensioning wheel 4 and the line dividing cavity 201, and the first elastic member 6 is used to provide pulling force.
[0043] In this embodiment, when the operator pulls the wire output from the right-side branch line outlet 203, the wire on the right side presses down the tensioning wheel 4 on the right side, and the first elastic member 6 on the right side is compressed downward, driving the lifting bracket 5 on the right side to descend, and the wire can smoothly slide out from the right-side branch line outlet 203. During this process, the wire on the left side is disengaged from the tensioning wheel 4 on the left side, the first elastic member 6 on the left side rises and resets, and the lifting bracket 5 on the left side rises, so that the tensioning wheel 4 on the left side blocks the branch line outlet 203 on the left side.
[0044] Optionally, it also includes: there are two positioning wheels 7, the two positioning wheels 7 are rotatably set in the line dividing cavity 201, the positioning wheel 7 is located between the line dividing wheel 3 and the tensioning wheel 4, and the wire passes through the line dividing wheel 3, the positioning wheel 7 and the tensioning wheel 4 in sequence.
[0045] In this embodiment, the positioning wheel 7 serves to limit the position of the conductor. Even if the tensioning wheel 4 on the left side rises, the conductor on the left side is still near the branching outlet 203 on the left side without being greatly offset.
[0046] Optionally, it also includes: a lifting block 8 is lifted and arranged in the junction box 2, the lifting block 8 has a wire inlet 801, the wire inlet 801 is connected with two branching inlets 202, and is connected with the wire groove 101, and the lifting block 8 is fixedly connected with the wire; the two ends of the second elastic member 9 act on the lifting block 8 and the junction box 2 respectively, and the second elastic member 9 is used to provide a force for the lifting block 8 to rise.
[0047] In this embodiment, after the wire passes through the end of the wire slot 101 away from the valve body, it is fixedly connected to the lifting block 8, and the operator then uses manpower to separate the wire into two strands. When the operator pulls the wire output from the right branch port, the lifting block 8 is pulled down to stretch the second elastic member 9. The lifting block 8 then drives the wire in the wire slot 101, so that the valve body is opened or closed by pulling the wire in the wire slot 101. It should be noted that an operating window 204 is provided on the branch box 2. When the wire passes through the lifting block 8, the operator can use manpower at the operating window 204 to separate the wire into two strands.
[0048] Optionally, it also includes: there are a plurality of positioning plates 10 , the plurality of positioning plates 10 are distributed in an array in the wire groove 101 , and the plurality of positioning plates 10 all have a wire threading hole 1001 .
[0049] Optionally, it also includes: the wire feeding roller group 11 has several groups, and one wire feeding roller group 11 is respectively arranged between each two adjacent positioning disks 10, and each wire feeding roller group 11 has two wire feeding roller bodies 1101 symmetrically and rotatably arranged on both sides of the wire passing groove 101, and a wire transportation space 1102 is formed between the two wire feeding roller bodies 1101. The wire passes through the wire threading hole 1001 and the wire transportation space 1102 in turn, and then passes through the wire passing groove 101.
[0050] In this embodiment, a plurality of positioning disks 10 are arranged inside the wire groove 101, which are arranged in an orderly manner, and each positioning disk 10 has a threading hole 1001. Such a design ensures that the wires are arranged in an orderly manner in the wire groove 101, avoiding tangled wires, and can be accurately guided through the threading hole 1001. A set of wire feeding roller groups 11 is installed between each two adjacent positioning disks 10, and each set of wire feeding roller groups 11 has two wire feeding roller bodies 1101 symmetrically arranged on both sides of the wire groove 101, and a wire transport space 1102 is formed between the two wire feeding roller bodies 1101. The rotation mechanism of the wire feeding roller body 1101 enables the wire to slide smoothly through the wire transport space 1102 after passing through the threading hole 1001, and smoothly transition to the outside of the wire groove 101. This reduces the friction resistance of the wire when passing through the wire groove 101, and protects the wire.
[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
