Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to an anti-static four-way ball valve with an outer protective structure. Background Art

[0002] At present, ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries, and they play an important role in the national economy. Ball valves can not only flexibly control the confluence, diversion, and flow direction switching of media on pipelines, but also close any channel and connect the other two channels. Among them, the four-way ball valve can switch the flow direction of two media at the same time, which is convenient and fast, and achieves the effect of one valve for multiple uses.

[0003] For some four-way ball valves installed in the factory, since they have no protective structure, cars or carts passing through the factory can easily hit the four-way ball valves, making them easily damaged. In addition, since the ball valves are inconvenient to disassemble and assemble, the maintenance cost is high and difficult to control. In addition, traditional valves do not have anti-static function, and static electricity can easily cause combustion of flammable media, posing a huge safety hazard.

[0004] Therefore, we propose an anti-static four-way ball valve with an outer protection structure to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an anti-static four-way ball valve with an outer protective structure.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: an anti-static four-way ball valve with an outer protective structure, comprising a four-way ball valve body, a destaticizing component for conducting electricity is installed at the bottom of the four-way ball valve body, a buffer component and a guide component fixedly connected together for anti-collision are arranged around the four-way ball valve body, and the buffer component is fixedly connected to the four-way ball valve body, wherein:

[0007] A buffer assembly, the buffer assembly comprising a mounting frame fixedly connected to the four-way ball valve body, and four shock absorbers for mitigating impact force are hinged on the mounting frame;

[0008] A guide assembly, the guide assembly includes a mounting plate hinged to four shock absorbers, the mounting plate is arranged in a V shape, a plurality of guide rollers 1 are rotatably mounted on the mounting plate, and inclined side plates are fixedly mounted on both sides of the mounting plate, and a plurality of guide rollers 2 are rotatably mounted on the side plates.

[0009] Preferably, the four-way ball valve body comprises a valve body, the valve body is provided with four valve channels, a connecting column fixedly connected to the valve body is provided between two adjacent valve channels, and the connecting column is fixedly connected to the mounting frame.

[0010] Preferably, the anti-static component comprises a wire fixedly connected to the valve body, and a conductive block is fixedly mounted on the bottom end of the wire.

[0011] Preferably, two V-shaped frames are hinged on both sides of the mounting frame, the two V-shaped frames on the same side are hinged with the same hinge block, and the ends of the four shock absorbers away from the guide assembly are respectively hinged to the corresponding hinge blocks.

[0012] Preferably, two cross bars are fixedly mounted on one side of the mounting plate close to the mounting frame, and one end of the four shock absorbers close to the guide assembly is hinged to the corresponding cross bars respectively.

[0013] Preferably, a gas spring is fixedly mounted on one side of the hinge block close to the four-way ball valve body, and a flexible block is fixedly mounted on one end of the gas spring away from the hinge block.

[0014] Preferably, the guide roller 1 and the guide roller 2 both include flexible sleeves.

[0015] Preferably, the shock absorber comprises a shock absorbing oil cylinder, both ends of the shock absorbing oil cylinder are fixedly mounted with mounting plates, a same shock absorbing spring is fixedly mounted between the two mounting plates, and the shock absorbing spring sliding sleeve is arranged on the shock absorbing oil cylinder.

[0016] Preferably, a reinforcing purlin is fixedly mounted on one side of the mounting plate close to the buffer assembly, and two ends of the reinforcing purlin are respectively fixedly connected to two cross bars.

[0017] Preferably, a plurality of damping shafts are rotatably mounted on the mounting plate and the side plate, and a plurality of guide rollers 1 and a plurality of guide rollers 2 are respectively fixedly sleeved on the corresponding damping shafts.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When static electricity is formed on the four-way ball valve body, the static electricity will lead to the pre-buried grounded conductive block through the wire, and then the static electricity will be directed to the ground through the conductive block, thereby ensuring that there will be no static electricity accumulation on the four-way ball valve body. If an object hits the four-way ball valve body from the side, the impactor will first contact the guide assembly. No matter whether the impactor hits the two sides or the upper and lower parts of the guide assembly, the guide assembly will guide the impact force of the impactor to its own center. During this guiding process, the speed of the impactor will be slowed down to a certain extent, and then the impactor will push against the buffer assembly through the guide assembly. The four shock absorbers on the buffer assembly will be able to greatly buffer the impact force of the impactor through their own deformation and displacement, so that the impact force acting on the four-way ball valve body can be within the bearing range of the four-way ball valve body, and will not cause destructive effects on the four-way ball valve body.

[0020] 1. The present invention can prevent the impact object from directly hitting the four-way ball valve body from the side through the buffer assembly and the guide assembly located around the four-way ball valve body, so it can play a certain protective role on the four-way ball valve body. The impact force is slowed down by the buffer assembly, so that the impact force finally acting on the four-way ball valve body is completely within the bearing range of the four-way ball valve body, thereby avoiding irreversible damage to the four-way ball valve body.

[0021] 2. The present invention conducts the static electricity generated on the four-way ball valve body to the ground through the anti-static component, so that the entire four-way ball valve body has an anti-static function, is effectively protected, and improves the safety of fluid flowing through the four-way ball valve body.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example

[0032] refer to Figure 1-7 In this embodiment, an anti-static four-way ball valve with an outer protective structure is proposed, including a four-way ball valve body 1, a destaticizing component 2 for conducting electricity is installed at the bottom of the four-way ball valve body 1, and a buffer component 3 and a guide component 4 fixedly connected together for anti-collision are arranged around the four-way ball valve body 1, and the buffer component 3 is fixedly connected to the four-way ball valve body 1, wherein:

[0033] The buffer assembly 3 includes a mounting frame 31 fixedly connected to the four-way ball valve body 1, and four shock absorbers 34 for mitigating impact force are hinged on the mounting frame 31;

[0034] The guide assembly 4 includes a mounting plate 41 hinged to four shock absorbers 34, the mounting plate 41 is arranged in a V-shape, and a plurality of guide rollers 42 are rotatably mounted on the mounting plate 41. Inclined side plates 43 are fixedly mounted on both sides of the mounting plate 41, and a plurality of guide rollers 44 are rotatably mounted on the side plates 43.

[0035] Furthermore, since the mounting plate 41 is V-shaped, when the impact force of the impact object falls on the upper side of the mounting plate 41, the deformed buffer component 3 will make the upper side of the mounting plate 41 close to the four-way ball valve body 1, and the lower side of the mounting plate 41 will be away from the four-way ball valve body 1 to form a tilt. Therefore, in the process of the buffer component 3 deforming and driving the mounting plate 41 to tilt, the impact force acting on the mounting plate 41 can be mitigated to a certain extent. When the impact force of the impact object acts on the lower side of the mounting plate 41, the deformed buffer component 3 will drive the mounting plate 41 to bend downward, and finally, after being guided by multiple guide rollers 42, the impact object will be moved to the center of the mounting plate 41, and finally the device force will act on the buffer component 3. When the impact object acts on On the side plates 43 on both sides, guided by multiple guide rollers 44 on the inclined side plates 43, the impact object will move to the center of the mounting plate 41 and transfer the impact force to the buffer assembly 3, and the impact force will be buffered by the buffer assembly 3. Finally, the impact force acting on the four-way ball valve body 1 is completely within the bearing range of the four-way ball valve body 1. Therefore, the impact force acting on the four-way ball valve body 1 can be reduced by four pairs of buffer assemblies 3 and guide assemblies 4, avoiding the four-way ball valve body 1 from suffering destructive blows, and the guide assembly 4 between the two valve channels 12 can prevent the impact object from hitting the valve channels 12 on both sides, thereby avoiding the four-way ball valve body 1 from being damaged due to side impacts.

[0036] The four-way ball valve body 1 comprises a valve body 11 , on which four valve channels 12 are arranged. A connecting column 13 fixedly connected to the valve body 11 is arranged between two adjacent valve channels 12 , and the connecting column 13 is fixedly connected to the mounting frame 31 .

[0037] The anti-static component 2 includes a wire 21 fixedly connected to the valve body 11 , and a conductive block 22 is fixedly mounted at the bottom end of the wire 21 .

[0038] Furthermore, the purpose of grounding is achieved by pre-burying the conductive block 22 in the wall or the ground, and then connecting the wire 21 connected to the valve body 11 to the conductive block 22. This can conduct the static electricity generated on the valve body 11 to the ground, preventing static electricity from accumulating on the valve body 11. This not only improves the safety of fluid transportation by the four-way ball valve body 1, but also prevents static electricity from causing discomfort to the staff.

[0039] Two V-shaped frames 32 are hinged on both sides of the mounting frame 31 , and a same hinge block 33 is hinged on the two V-shaped frames 32 on the same side. One end of the four shock absorbers 34 away from the guide assembly 4 is hinged to the corresponding hinge block 33 respectively.

[0040] Furthermore, the shock absorber 34 can be swung at a certain angle by means of the two V-shaped frames 32 and the hinge block 33, so that the impact force exerted on the shock absorber 34 can be side-unloaded, so that the impact force acting on the mounting frame 31 is much smaller than the impact force acting on the shock absorber 34. Therefore, the impact force finally exerted on the four-way ball valve body 1 through the mounting frame 31 is completely within the bearing range of the four-way ball valve body 1, thereby avoiding destructive damage to the guide assembly 4 due to the impact.

[0041] Two cross bars 35 are fixedly mounted on one side of the mounting plate 41 close to the mounting frame 31 , and one end of the four shock absorbers 34 close to the guide assembly 4 is hinged to the corresponding cross bars 35 .

[0042] Furthermore, by hingedly connecting two corresponding shock absorbers 34 together through the cross bar 35 , the two shock absorbers 34 can be deformed synchronously, and the impact force received by the mounting plate 41 can be fully applied to the four shock absorbers 34 .

[0043] A gas spring 331 is fixedly mounted on one side of the hinge block 33 close to the four-way ball valve body 1 , and a flexible block 332 is fixedly mounted on one end of the gas spring 331 away from the hinge block 33 .

[0044] Furthermore, when the four shock absorbers 34 are deformed and displaced by the impact force, the two hinge blocks 33 will approach the valve body 11. During this process, the flexible block 332 will first contact the valve body 11. Then, as the hinge block 33 continues to approach the valve body 11, the gas spring 331 will shrink, which can prevent the hinge block 33 from directly hitting the valve body 11, thereby providing better protection for the valve body 11.

[0045] The guide roller 1 42 and the guide roller 2 44 both include flexible sleeves.

[0046] Furthermore, by providing a flexible sleeve, guide roller 1 42 and guide roller 2 44 can be protected to a certain extent, and impact objects can be prevented from hitting guide roller 1 42 and guide roller 2 44 and causing damage to guide roller 1 42 and guide roller 2 44. At the same time, the deformation of the flexible sleeve can slightly reduce the impact force acting on guide roller 1 42 and guide roller 2 44.

[0047] The shock absorber 34 comprises a shock absorbing oil cylinder, both ends of which are fixedly mounted with mounting plates, a same shock absorbing spring is fixedly mounted between the two mounting plates, and the shock absorbing spring is slidably sleeved on the shock absorbing oil cylinder.

[0048] Furthermore, by providing a shock-absorbing cylinder and a shock-absorbing spring, the impact force can be buffered for a second time. Even if one of the shock-absorbing cylinder or the shock-absorbing spring fails, the other component can still work normally, so the failure rate is low.

[0049] A reinforcing purlin is fixedly mounted on one side of the mounting plate 41 close to the buffer assembly 3 , and both ends of the reinforcing purlin are respectively fixedly connected to the two cross bars 35 .

[0050] Furthermore, by providing a purlin on the back of the mounting plate 41, a certain support can be provided between the two cross bars 35, so that when the four shock absorbers 34 are deformed or displaced, the distance between the two cross bars 35 will not change, and at the same time, the relative positions of the four shock absorbers 34 will not change, ensuring that after the impactor moves away from the guide assembly 4, the four shock absorbers 34 can be quickly reset to meet the next impact.

[0051] A plurality of damping shafts are rotatably mounted on the mounting plate 41 and the side plate 43 , and a plurality of guide rollers 1 42 and a plurality of guide rollers 2 44 are respectively fixedly sleeved on the corresponding damping shafts.

[0052] Furthermore, by providing a damping shaft, the rotation of guide roller 1 42 and guide roller 2 44 can be damped. Therefore, when the impactor hits guide roller 1 42 or guide roller 2 44, the mounting plate 41 will tilt to a certain extent, so that the impactor can automatically move to the center of the guide assembly 4. Therefore, the impactor rolls through multiple guide rollers 1 42 or multiple guide rollers 2 44 in sequence. Since guide roller 1 42 and guide roller 2 44 will generate a certain resistance during the rotation process, not only can the speed of the impactor moving to the center of the guide assembly 4 be slowed down, but the resistance generated by the rotation of guide roller 1 42 and guide roller 2 44 can also slow down the impact force of the impactor to a certain extent.

[0053] In the present embodiment, after static electricity is formed on the four-way ball valve body 1, the static electricity will lead to the pre-buried grounded conductive block 22 through the wire 21, and then the static electricity will be directed to the ground through the conductive block 22, thereby ensuring that no static electricity will accumulate on the four-way ball valve body 1. If an object hits the four-way ball valve body 1 from the side, the impactor will first contact the guide assembly 4. Regardless of whether the impactor hits the two sides or the upper and lower parts of the guide assembly 4, the guide assembly 4 will guide the impact force of the impactor to its own center. During this guiding process, the speed of the impactor will be slowed down to a certain extent. Then, the impactor will push against the buffer assembly 3 through the guide assembly 4. The four shock absorbers 34 on the buffer assembly 3 will be able to greatly buffer the impact force of the impactor through their own deformation and displacement, so that the impact force acting on the four-way ball valve body 1 can be within the bearing range of the four-way ball valve body 1, and will not cause destructive effects on the four-way ball valve body 1.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
