[0002] A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. The valve can be operated manually or with a handwheel, handle or pedal. The pressure, temperature and flow rate of the fluid medium can also be changed through control. When using corrosion-resistant valves, it is necessary to install nylon components inside the valve to prevent long-term wear and rust on the mechanical transmission parts.

[0014] The present invention also provides a method for preparing a corrosion-resistant valve, comprising the following steps: Step S1: First, the transmission mechanism is started to make the whole equipment run, and then the external welding machine arm is installed on the fixed plate. Then, the valve to be welded is placed on the conveyor belt, and the valve is conveyed to the bottom of the clamping positioning member through the conveyor belt for clamping. During the clamping process, the injection mechanism is opened to feed the material and the contact component is triggered, so that the material supplied by the injection mechanism can flow to the outer surface of the valve; Step S2: When the transmission mechanism is working, the motor drives the transmission gear to rotate, and then drives the driven gear to rotate. When the driven gear rotates, it can drive the clamping positioning piece to work, and at the same time drive the turntable to rotate. When the turntable rotates, it can not only drive the conveyor belt to drive, but also drive the ratchet to move intermittently, thereby driving the rectangular conveying block to intermittently convey the processed valve; Step S3: When the pressing and positioning member is working, the movable plate can be pressed downward by the rotation of the cam, thereby driving the limit box inside the pressing frame to press the valve delivered, and the injection mechanism and the contact component will be triggered during the pressing; Step S4: When the injection mechanism is working, the movable plate will drive the adjusting rod to slide downward during the downward movement, so that the buffer chamber slides into the inside of the main pipeline and is connected with the main pipeline through the first side port.

At this time, the valve body can be compacted, and at the same time, the opening of the guide hole on the guide rod will slide into the inner cavity, and the liquid inside the inner cavity will be introduced into the through hole through the guide hole, and finally injected into the sponge block inside the limit box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention starts the transmission mechanism to make the whole equipment run, then installs the external welding machine arm on the fixed plate, and then presses the valve by the pressing positioning piece. During the pressing process, the valve is quickly welded by the external welding machine arm. At the same time, the injection mechanism is opened to feed and the contact assembly is triggered, so that the anti-corrosion material supplied by the injection mechanism can flow to the outer surface of the valve; 2. The present invention is provided with a transmission mechanism, which is convenient for driving the entire equipment to operate. When the transmission mechanism is working, the motor drives the transmission gear to rotate, and then drives the driven gear to rotate. When the driven gear rotates, it can drive the pressing and positioning member to work, and at the same time drive the turntable to rotate. When the turntable rotates, it can not only drive the conveyor belt to drive, but also drive the ratchet to move intermittently, thereby driving the rectangular conveying block to intermittently convey the processed valve; 3. The present invention is provided with a clamping positioning member, which is conducive to clamping and fixing the valve. When the clamping positioning member is working, the movable plate can be pressed downward by the rotation of the cam, thereby driving the limit box inside the lower pressing frame to clamp the valve conveyed over; 4. The present invention is advantageous for coating the outer surface of the valve by providing an injection mechanism and a contact assembly. When the injection mechanism is working, the movable plate will drive the adjusting rod to slide downward during the downward movement, and the buffer chamber will slide and communicate with the main pipeline through the first side port. At the same time, the transition chamber will communicate with the hose through the second side port, so that the fluid inside the main pipeline can flow to the inner cavity inside the limit box. When the contact assembly is working, when the limit box and the valve are pressed together, the frame is pressed upward, so that the top of the guide rod slides toward the inner cavity until the top of the frame fits with the bottom of the limit box. At this time, the liquid inside the inner cavity is introduced into the through hole through the guide hole on the guide rod, and finally injected into the sponge block inside the limit box.

[0019] See also Figure 1-8 The present invention provides a technical solution: a corrosion-resistant valve welding processing equipment, comprising a conveying frame 1 and a fixing frame 3, the fixing frame 3 is installed at the middle of the top of the conveying frame 1, a fixing plate 2 is installed between the top of the fixing frame 3 near one side edge, a transmission mechanism is arranged at the front side of the conveying frame 1, a material injection mechanism is arranged between the inner walls of both sides of the fixing frame 3, and a pressing and positioning piece is arranged between the inner walls of both sides of the fixing frame 3 on one side of the material injection mechanism; Two conveying rollers 26 are rotatably connected between the inner walls of the conveying frame 1, and a conveyor belt 6 is arranged between the outer surfaces of the two conveying rollers 26. Guide strips 7 are fixed to the inner walls on both sides of the conveying frame 1, and one end of the two guide strips 7 is inclined to extend toward the middle part of the conveyor belt 6, and the inclined ends of the two guide strips 7 extend to just below the clamping positioning member. A guide plate 12 is arranged between the inner walls of the conveying frame 1, and a rotating shaft 20 is rotatably connected between the inner walls of the conveying frame 1. A rectangular conveying block 21 is fixed to the outer surface of the rotating shaft 20, and the outer surface of the rectangular conveying block 21 is concave, and a magnetic sheet 22 is arranged inside the concave outer surface of the rectangular conveying block 21.

[0020] The effect achieved is that, first, the transmission mechanism is started to make the whole equipment run, and then the external welding machine arm is installed on the fixed plate 2, and then the valve to be welded is placed on the conveyor belt 6, and the conveyor belt 6 is driven by the rotation of the conveying roller 26 to convey the valve to the bottom of the clamping positioning piece for clamping. During the clamping process, the injection mechanism is opened to feed and the contact component is triggered at the same time, so that the material supplied by the injection mechanism can flow to the outer surface of the valve, and a magnetic sheet 22 is set in the recessed part of the outer surface of the rectangular conveying block 21 to facilitate the subsequent magnetic adsorption of the valve and then intermittent transmission.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the transmission mechanism includes a motor 9, a support 8 is fixed to the outside of the motor 9, one end of the support 8 is mounted on the fixed frame 3, a transmission gear 13 is fixed to the output end of the motor 9, a driven gear 10 is rotatably connected to the front side of the fixed frame 3, the driven gear 10 and the transmission gear 13 are meshed with each other, a turntable 14 is rotatably connected to the front side of the conveying frame 1, a gear ring 15 is fixed to the rear side of the turntable 14, the gear ring 15 and the driven gear 10 are meshed with each other, a semicircular block 19 is fixed to the front side of the turntable 14, and a dial is fixed near the edge of the outer surface of the turntable 14 Rod 16, the front side of the conveying frame 1 is rotatably connected to the ratchet 11 near the turntable 14, the outer surface of the ratchet 11 is provided with a plurality of semicircular openings 17 equidistantly along the circumferential direction, the outer surface of the ratchet 11 is provided with a plurality of shifting openings 18 equidistantly along the circumferential direction, the plurality of shifting openings 18 are correspondingly located between two adjacent semicircular openings 17, the semicircular blocks 19 and the semicircular openings 17 are slidably fitted with each other, the shifting rod 16 is located inside the shifting openings 18, one end of the rotating shaft 20 is fixed on the ratchet 11, and one end of one of the conveying rollers 26 is fixed on the turntable 14.

[0022] The effect achieved is that the transmission gear 13 is driven to rotate by the motor 9, and then the driven gear 10 is driven to rotate. When the driven gear 10 rotates, it can drive the clamping positioning piece to work. At the same time, since the driven gear 10 and the ring gear 15 are meshed with each other, and the ring gear 15 is fixed to the rear side of the turntable 14, the turntable 14 can be driven to rotate. When the turntable 14 rotates, it can not only drive the conveyor belt 6 to transmit, but also drive the ratchet 11 to move intermittently, thereby driving the rectangular transmission block 21 to intermittently transport the processed valves. When the ratchet 11 is driven to transmit, when the semicircular mouth 17 and the semicircular block 19 are engaged with each other, the ratchet 11 is in a positioning state and will not rotate. When the semicircular mouth 17 and the semicircular block 19 are separated, the ratchet 11 is in a contact positioning state. At this time, the lever 16 slides into the interior of the lever mouth 18, and the ratchet 11 is driven to rotate under the tossing of the lever 16, thereby driving the rectangular transmission block 21 to rotate.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping positioning member includes a movable plate 27, guide openings 23 are provided on the front and rear sides of the fixed frame 3, guide rods 24 are fixed between the inner top and bottom surfaces of the two guide openings 23, the movable plate 27 is slidably connected between the two guide rods 24, first springs 25 are fixed at the top of the movable plate 27 near the two end edges, one end of the two first springs 25 is fixed to the inner top surface of the guide opening 23, two rollers 28 are rotatably connected to the movable plate 27, a lower pressing frame 32 is fixed at the bottom of the movable plate 27 in the middle, and a transmission shaft 29 is rotatably connected between the inner walls of the two sides of the fixed frame 3. Two cams 30 are fixed to the outer surface of the transmission shaft 29, and the outer surfaces of the two cams 30 correspond to the outer surface of the roller 28 and fit each other. One end of the transmission shaft 29 is fixed to the driven gear 10, and a rear baffle 31 is fixed to one side of the lower pressing frame 32, and a front baffle 33 is fixed to the other side of the lower pressing frame 32. A limit box 40 is fixed between the inner walls of the lower pressing frame 32, and a contact assembly is provided at the bottom. The bottom of the limit box 40 is open, and a limit frame 43 is fixed between the inner walls of the limit box 40. A sponge block 41 is provided between the inner walls of the limit box 40, and the limit frame 43 is engaged with the outer side of the sponge block 41.

[0024] The effect achieved is that the transmission shaft 29 rotates, which drives the cam 30 to rotate and press the movable plate 27 downward, thereby driving the limit box 40 inside the pressing frame 32 to press the valve conveyed over. During the pressing process, the first spring 25 will be stretched downward, thereby pulling the movable plate 27 upward, so that there is always a pressing force between the roller 28 and the outer surface of the cam 30. During the pressing process of the movable plate 27, the valve on the conveyor belt 6 is first blocked by the front baffle 33, and then the valve conveyed below the limit box 40 is prevented from sliding out from one side of the conveyor belt 6 by the rear baffle 31.

[0025] like Figure 6 and Figure 8 As shown, the contact assembly includes a frame 42, which is located below the limit box 40. The side walls of the limit box 40 are provided with adjustment cavities 46 near the two side edges, and the side walls of the limit box 40 are provided with an inner cavity 44 near the top edge. Guide rods 47 are provided inside the two adjustment cavities 46, and the tops of the two guide rods 47 slide through the inner cavity 44. Through holes 45 are provided on the inner walls on both sides of the limit box 40, and one end of the two through holes 45 penetrates to the outer surface of the guide rods 47. The outer surfaces of the two guide rods 47 are located inside the adjustment cavity 46 and fixed with fixing rings 49. A second spring 48 is fixed between the tops of the two fixing rings 49 and the inner top surface of the adjustment cavity 46. The outer surfaces of the two guide rods 47 are provided with guide holes 50, and the bottoms of the two guide rods 47 slide through to the bottom of the limit box 40, and the frame 42 is fixed between the bottoms of the two guide rods 47.

[0026] The effect achieved is that when the limit box 40 and the valve are pressed against each other, the sponge block 41 first contacts the valve body. During the compression of the sponge block 41 into the limit box 40, the frame 42 will be pressed upward, so that the top of the guide rod 47 slides toward the inner cavity 44 until the top of the frame 42 and the bottom of the limit box 40 fit each other. At this time, the valve body can be compacted, and at the same time, the opening of the guide hole 50 on the guide rod 47 will slide into the inner cavity 44, and the liquid in the inner cavity 44 will be introduced into the through hole 45 through the guide hole 50, and finally injected into the sponge block 41 inside the limit box 40. When the injection mechanism is opened and there is no compaction between the contact positioning piece and the valve body, the contact component will not be triggered, that is, the material supplied by the injection component cannot flow to the valve body. The function of the contact component here is to detect whether the contact positioning piece is compacted with the valve body, and to play a protective role to prevent the situation where the valve body is supplied with material before the valve body is compacted.

[0027] like Figure 1 and Figure 5 As shown, the injection mechanism includes a main pipeline 4, which is connected between the inner walls of the fixing frame 3, and one end of the main pipeline 4 passes through the outside of the fixing frame 3. An adjusting tube 5 is fixed at the middle of the outer surface of the main pipeline 4. The adjusting tube 5 and the main pipeline 4 are connected to each other, and the bottom of the adjusting tube 5 extends to the bottom of the main pipeline 4. A hose 39 is connected to the outer surface of the adjusting tube 5 near the bottom edge. One end of the hose 39 is connected to the top of the limit box 40 and passes through the inner cavity 44. An adjusting rod 34 is slidably connected to the inside of the adjusting tube 5. A buffer cavity 35 is opened near the top edge of the adjusting rod 34. The inner wall of the buffer cavity 35 is equidistantly provided with a plurality of first side openings 37 that pass through to the outside along the circumferential direction. A transition cavity 36 is opened below the buffer cavity 35 in the adjusting rod 34. The inner wall of the transition cavity 36 is equidistantly provided with a plurality of second side openings 38 that pass through to the outside along the circumferential direction. The inner bottom surface of the buffer cavity 35 and the inner top surface of the transition cavity 36 are connected to each other. The bottom of the adjusting rod 34 is fixed on the lower pressing frame 32.

[0028] The effect achieved is that when the movable plate 27 moves downward, the adjusting rod 34 will be driven to slide downward, so that the buffer chamber 35 slides into the inside of the main pipe 4, and is connected with the main pipe 4 through the first side port 37. At the same time, the transition chamber 36 is connected with the hose 39 through the second side port 38, so that the fluid inside the main pipe 4 can flow to the inner cavity 44 inside the limit box 40. When the movable plate 27 is not pressed down, the buffer chamber 35 is located inside the adjusting tube 5 above the main pipe 4. At this time, the inside of the main pipe 4 and the buffer chamber 35 are in a closed state, and the material inside the main pipe 4 cannot flow to the hose 39, that is, when the clamping positioning member does not work, the injection mechanism does not work either.

[0029] The main problem solved by this embodiment is: after the transmission mechanism is started to make the whole equipment run, the external welding machine arm is installed on the fixed plate 2, and then the valve is pressed by the pressing positioning piece. During the pressing process, the valve is quickly welded by the external welding machine arm. At the same time, the injection mechanism is opened to feed and the contact component is triggered, so that the anti-corrosion material supplied by the injection mechanism can flow to the outer surface of the valve, which solves the problem that it takes a certain amount of time to transport the valve to the spraying area after welding, and the weld will be severely oxidized during this process, which is not convenient for subsequent coating. A method for preparing a corrosion-resistant valve includes the following steps: Step S1: First, the transmission mechanism is started to make the whole equipment run, and then the external welding robot arm is installed on the fixed plate 2, and then the valve to be welded is placed on the conveyor belt 6, and the valve is conveyed to the bottom of the clamping positioning member by the conveyor belt 6 for clamping, and during the clamping process, the injection mechanism is opened to feed the material and the contact component is triggered, so that the material supplied by the injection mechanism can flow to the outer surface of the valve; Step S2: When the transmission mechanism is working, the motor 9 drives the transmission gear 13 to rotate, and then drives the driven gear 10 to rotate. When the driven gear 10 rotates, it can drive the pressing and positioning member to work, and at the same time drive the turntable 14 to rotate. When the turntable 14 rotates, it can not only drive the conveyor belt 6 to transmit, but also drive the ratchet 11 to intermittently move, thereby driving the rectangular conveying block 21 to intermittently convey the processed valves; Step S3: When the pressing and positioning member is working, the movable plate 27 can be pressed downward by the rotation of the cam 30, thereby driving the limit box 40 inside the pressing frame 32 to press the valve delivered, and the injection mechanism and the contact component will be triggered during the pressing; Step S4: When the injection mechanism is working, the movable plate 27 moves downward, which drives the adjusting rod 34 to slide downward, so that the buffer chamber 35 slides into the inside of the main pipeline 4, and is connected with the main pipeline 4 through the first side port 37. At the same time, the transition chamber 36 is connected with the hose 39 through the second side port 38, so that the fluid inside the main pipeline 4 can flow to the inner cavity 44 inside the limit box 40; Step S5: When the contact assembly is working, when the limit box 40 and the valve are pressed together, the first thing that contacts the valve body is the sponge block 41. During the compression of the sponge block 41 into the limit box 40, the frame 42 will be pressed upward, so that the top of the guide rod 47 slides toward the inner cavity 44 until the top of the frame 42 and the bottom of the limit box 40 fit each other. At this time, the valve body can be compacted, and at the same time, the opening of the guide hole 50 on the guide rod 47 will slide into the inner cavity 44, and the liquid inside the inner cavity 44 will be introduced into the through hole 45 through the guide hole 50, and finally injected into the sponge block 41 inside the limit box 40.
