Description

Technical Field

[0001] This utility model relates to valve castings, and more particularly to a valve with a cleaning function. Background Technology

[0002] A valve is a control component in a fluid transport system, used to open and close pipelines, control the flow direction, and regulate and control the parameters of the transported medium. It typically includes a valve body, a valve stem that can rotate or be adjusted vertically, and a valve disc fixed to the valve stem (the valve stem and valve disc may have different shapes and structures depending on the type of valve). The valve body includes fluid channels located on the left and right sides of the valve disc. By moving the valve stem and valve disc vertically or rotating them, the fluid channels at both ends can be connected or cut off.

[0003] For valves that have not yet been put into use, a large amount of dust and particulate matter may accumulate in their fluid passages, which need to be cleaned. Cleaning the fluid passages usually involves directly letting water flow from the inlet to the outlet, with the water flowing through the fluid passages to flush them. However, if you want to clean the fluid passages further, you need to pour cleaning fluid into them. This requires tilting the valve body to make the cleaning fluid flow on the inner wall of the valve body, which makes it inconvenient to put the cleaning fluid into the valve.

[0004] Therefore, how to enable the cleaning agent to enter the fluid channel of the valve body more smoothly has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a valve with a cleaning function that allows the cleaning agent in the storage chamber to reach the left flow channel and, in conjunction with the water flow, flush the inner wall of the valve body by pressing down the piercing member before activating the valve.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a valve body, a valve stem, a valve ball, and a valve seat. The valve stem is rotatably mounted on the valve body, and the valve ball is fixedly mounted at its bottom. There are two valve seats, located on the left and right sides of the valve ball, respectively. The valve body has a left flow channel and a right flow channel on the left and right sides of the valve ball, respectively. It also includes a cleaning section. The valve body includes a left connecting section located on the left side of the valve ball and a right connecting section containing the valve ball. The left and right connecting sections are detachably connected. The cleaning section is located above the left connecting section and is detachably connected to it. The cleaning section includes a cleaning seat, a storage cavity within the cleaning seat, thin films fixed to the cleaning seat on the upper and lower sides of the storage cavity, and a piercing element for piercing each film. The cleaning seat has a liquid passage hole at its bottom that communicates with the left flow channel. The top of the piercing element is detachably connected to the top of the cleaning seat.

[0007] The present invention is further configured such that: the cleaning part also includes a cooperating spring, the puncture member includes a top cover and a working section, the cooperating spring is located in the circumferential direction of the working section and one end is fixedly connected to the top cover, and the other end is fixedly connected to the cleaning seat.

[0008] The present invention is further configured such that: the cleaning seat is made of a material that is prone to deformation and includes a first mounting section, a second mounting section and a third mounting section from top to bottom; the left connecting part is provided with a mounting groove corresponding to the second mounting section; the first mounting section is detachably connected to the left connecting part; and the diameter of the third mounting section is larger than the diameter of the mounting groove and abuts against the left mounting part.

[0009] The present invention is further configured such that: positioning blocks are fixedly installed on both the left and right sides of the bottom of the first mounting section, and each positioning block is inserted into the left connecting part and is detachably connected to the left connecting part.

[0010] The present invention is further configured such that: the left connecting part is provided with a positioning slot for each positioning block, each positioning block is provided with a mating slot recessed inward, each mating slot is arranged in a ring shape, and the left connecting part is provided with a mating block located in each positioning slot.

[0011] The present invention is further configured such that: a first magnet is provided at the bottom of the upper cover, and a second magnet is provided in the first mounting section corresponding to the first magnet.

[0012] The present invention is further configured such that the bottom of the working section is a tapered shape that narrows from top to bottom and from the outside to the inside.

[0013] By adopting the above technical solution, when the valve needs to be activated, the piercing member is moved downwards, causing its bottom to penetrate the two thin films located in the cleaning seat in sequence. At this time, the cleaning agent and cleaning powder in the storage chamber can move downwards as the films are broken and fall into the left flow channel of the left connection part through the liquid passage on the cleaning seat. Therefore, the liquid that first enters the left flow channel will mix with the cleaning agent and cleaning powder, thereby achieving a more thorough flushing of the valve body wall and flowing out from the right flow channel. Since the top of the piercing member is detachably connected to the top of the cleaning seat, after the films are pierced and the material in the storage chamber moves downwards, the top of the piercing member will continuously approach the top of the cleaning seat and then connect with the top of the cleaning seat. Thus, during the use of the valve, if the liquid in the left flow channel enters the liquid passage and splashes upwards, it will be blocked by the top of the piercing member and will not flow out of the valve.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-5As shown, this utility model discloses a valve with a cleaning function, including an electric actuator 7 (which is prior art and will not be described in detail here), a valve body 1 located below the electric actuator 7, a valve stem 2, a valve ball 3, and a valve seat 4. The valve stem 2 is rotatably mounted on the valve body 1, and the valve ball 3 is fixedly mounted on its bottom by welding or other means. There are two valve seats 4, located on the left and right sides of the valve ball 3, respectively. The valve body 1 has a left flow channel 11 and a right flow channel 12 on the left and right sides of the valve ball 3, respectively. The valve ball 3 has a mating channel 31 that connects the left side to the left flow channel 11 and the right side to the right flow channel 12. The electric actuator 7 can drive the valve stem 2 to rotate, which in turn drives the valve ball 3 to rotate, thereby enabling the mating channel 31 on the valve ball 3 to rotate. The left and right sides of channel 31 are connected to the left flow channel 11 and the right flow channel 12 respectively, allowing the liquid on the left side of the valve to flow to the right side of the valve body 1 through the valve ball 3. Reverse rotation of the valve stem 2 causes the mating channel 31 on the valve ball 3 to be misaligned with the left flow channel 11 and the right flow channel 12, thus achieving liquid cut-off (this is prior art and will not be elaborated here). It also includes a cleaning section 5. The valve body 1 includes a left connecting part 13 located to the left of the valve ball 3 and a right connecting part 14 containing the valve ball 3. The left connecting part 13 and the right connecting part 14 are detachably connected by bolts. The left flow channel 11 is located within the left connecting part 13, the right flow channel 12 is located within the right connecting part 14, and the cleaning section 5 is located within the left connecting part 13. Above the connecting part 13 and detachably connected to the left connecting part 13, the cleaning part 5 includes a cleaning seat 51, a storage cavity 511 for storing cleaning agents, cleaning powders, and other cleaning substances located within the cleaning seat 51, thin films 512 fixed to the cleaning seat 51 on the upper and lower sides of the storage cavity 511, and piercing elements 513 for piercing each of the thin films 512. The cleaning seat 51 has a liquid passage hole 514 at its bottom that communicates with the left flow channel 11. The top of the piercing element 513 is detachably connected to the top of the cleaning seat 51 by magnetic attraction, fastening, or other means. When the valve needs to be activated, the piercing element 513 is moved down, causing its bottom to sequentially penetrate the two thin films 512 located within the cleaning seat 51. The cleaning agent and cleaning powder in the storage chamber 511 can move downwards as the membranes 512 are broken, and then fall into the left flow channel 11 of the left connecting part 13 through the liquid passage 514 on the cleaning seat 51. Therefore, the liquid that first enters the left flow channel 11 will mix with the cleaning agent and cleaning powder, thus achieving a more thorough flushing of the inner wall of the valve body 1, and then flow out from the right flow channel 12. Since the top of the piercing member 513 is detachably connected to the top of the cleaning seat 51, after the membranes 512 are pierced and the material in the storage chamber 511 moves downwards when pressed down, the top of the piercing member 513 will continuously approach the top of the cleaning seat 51 and then connect with the top of the cleaning seat 51, thus making the valve more efficient during use.If liquid in the left flow channel 11 enters the liquid inlet 514 and splashes upwards, it will be blocked by the top of the piercing element 513 and will not flow out of the valve. Furthermore, because the cleaning seat 51 has two thin films 512 on both sides, the cleaning material needs to be pierced through the lower film 512 before it can pass through the liquid inlet 514 into the left flow channel 11. Therefore, without external force, the film 512 on the cleaning seat 51 is difficult to pierce, thus allowing the cleaning material to remain more stably within the storage chamber 511.

[0029] It is also worth noting that you can refer to the appendix. Figure 1 The left side of the left connecting part 13 is higher than the right side. Therefore, during the storage of the valve, when an object above the valve is inserted, it will first come into contact with the left side of the left connecting part 13, that is, the side with a higher height. Therefore, without the action of external force, the piercing part 513 cannot get enough force to move down and pierce the two layers of film 512. Therefore, the cleaning substance will not enter the left flow channel 11 downward.

[0030] The cleaning section 5 also includes a cooperating spring 515. The piercing member 513 includes a top cover 5131 and a working section 5132. The cooperating spring 515 is located circumferentially in the working section 5132, with one end fixedly connected to the top cover 5131 by welding or other means, and the other end fixedly connected to the cleaning seat 51 by welding or other means. Since one end of the cooperating spring 515 is fixed to the top cover 5131 and the other end is fixed to the cleaning seat 51, pressing down on the piercing member 513 compresses the cooperating spring 515. When the downward force is insufficient to compress the cooperating spring 515 and cause the piercing member 513 to pierce the two layers of film 512, the force of the cooperating spring 515 will drive the top of the piercing member 513 to return to its original position and move away from the two layers of film 512 after releasing the pressure. Therefore, the cooperating spring 515 can reduce the possibility of the film 512 being pierced by unauthorized personnel.

[0031] Preferably, the cleaning seat 51 is made of a material that is easily deformable, such as rubber, and includes, from top to bottom, a first mounting section 516, a second mounting section 517, and a third mounting section 518. The left connecting part 13 is provided with a mounting groove 131 corresponding to the second mounting section 517. The first mounting section 516 and the left connecting part 13 are detachably connected by means of fastening, bolts, etc. The diameter of the third mounting section 518 is larger than the diameter of the mounting groove 131 and abuts against the left mounting part. Since the diameter of the third mounting section 518 is larger than the diameter of the mounting groove 131, The third mounting section 518 has a diameter of 1 and abuts against the left mounting part. Therefore, when the cleaning seat 51 is installed on the left connecting part 13, the third mounting section 518 needs to force its way over the mounting groove 131 so that the third mounting section 518 abuts against the left connecting part 13. After the cleaning seat 51 is fixed in position on the valve body 1, the upward flow of water in the valve body 1 will be restricted by the third mounting section 518 and the first mounting section 516 and will not be able to leak out of the valve body 1 through the gap between the cleaning seat 51 and the left connecting part 13, thereby improving the sealing performance of the valve body 1.

[0032] The first mounting section 516 has positioning blocks 6 fixedly installed on both sides of its bottom through integral molding, bonding or other methods. Each positioning block 6 is inserted into the left connecting part 13 and is detachably connected to the left connecting part 13 by means of fastening or other methods. After the third mounting section 518 is forcibly pushed past the mounting groove 131, the first mounting section 516 and the left connecting part 13 are at abutted. At this time, by inserting the positioning blocks 6 of the first mounting section 516 into the left connecting part 13, the relative position of the cleaning seat 51 and the left connecting part 13 can be determined, thereby completing the connection between the first mounting section 516 and the left connecting part 13.

[0033] Preferably, the left connecting portion 13 is provided with a positioning slot 132 corresponding to each positioning plug 6, and each positioning plug 6 is provided with a mating slot 61 recessed inward. Each mating slot 61 is arranged in a ring shape. The left connecting portion 13 is provided with a mating plug 1321 located in each positioning slot 132. When each positioning plug 6 on the first mounting section 516 is inserted into the corresponding positioning slot 132, due to the presence of each mating plug 1321, the part of each positioning plug 6 located below the mating slot 61 will first contact the corresponding mating plug 1321. When this part of each positioning plug 6 crosses... After the corresponding mating plug 1321 is inserted, each mating plug 1321 will fall into the corresponding mating slot 61, thereby realizing the mating of each positioning plug 6 with the corresponding positioning slot 132. When it is necessary to remove the cleaning seat 51 from the valve body 1, by applying an insertion force to the first mounting section 516, the part of each positioning plug 6 located below the mating slot 61 is forced upward and passes over the corresponding mating plug 1321, thereby separating each positioning plug 6 from the positioning slot 132. Then, after the third mounting section 518 is forced to pass over the mounting groove 131, the cleaning seat 51 can be removed from the left connecting part 13.

[0034] Furthermore, a first magnet 51311 is provided at the bottom of the upper cover 5131, and a second magnet 5161 is provided on the first mounting section 516 corresponding to the first magnet 51311. Therefore, after the piercing member 513 punctures the two layers of film 512, the first magnet 51311 on the upper cover 5131 at the top of the piercing member 513 will attract the second magnet 5161 on the first mounting section 516 of the cleaning seat 51, thereby making the upper cover 5131 stably positioned on the first mounting section 516, thus making it difficult for the liquid in the valve body 1 to pass through the cleaning seat 51 and flow out from the gap between the cleaning seat 51 and the piercing member 513.

[0035] Preferably, the bottom of the working section 5132 is a tapered shape that narrows from top to bottom and from outside to inside. Because the bottom of the working section 5132 is a tapered shape, the bottom of the puncture member 513 can more smoothly puncture the two layers of film 512 during the process of pressing the puncture member 513 to move downwards, so that the substance with cleaning function can flow to the left flow channel 11 through the liquid passage 514.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
