Description

Technical Field

[0001] This application relates to the field of cleaning device technology, and in particular to a valve seat cleaning device. Background Technology

[0002] After the valve seat is processed, it usually needs to be cleaned. Currently, ultrasonic cleaning tanks are commonly used to clean valve seats.

[0003] However, after the valve seat is cleaned in an ultrasonic cleaning tank, when it is removed from the tank, some dirt can still easily adhere to its surface due to the turbidity of the cleaning solution. Operators then need to place the valve seat in a cleaner cleaning solution for further cleaning, resulting in low cleaning efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a valve seat cleaning device that can improve the cleaning efficiency of valve seats.

[0005] To achieve the above objectives, this application adopts the following technical solution: A valve seat cleaning device for cleaning valve seats includes a flushing pipe, a flushing seat, a flushing head, and a dispensing component. The flushing seat and the flushing pipe are detachably connected. The flushing seat has a flushing channel, and the flushing pipe is at least partially inserted into the flushing channel and is movable relative to the flushing channel. A first flushing hole is formed on the side wall of the flushing seat, and the first flushing hole communicates with the flushing channel. The flushing head is detachably installed on the top of the flushing seat, and a flushing chamber is formed inside the flushing head, communicating with the flushing channel. The flushing head also has a second flushing hole, which communicates with the flushing chamber. The dispensing component is installed in the flushing channel and is movable relative to the flushing channel, such that the dispensing component includes a first use state for closing the flushing chamber and a second use state for connecting the flushing channel and the flushing chamber. When the dispensing component is in the first use state, the flushing liquid in the flushing pipe flushes the valve seat through the first flushing hole. When the dispensing component is in the second use state, the flushing liquid in the flushing pipe flushes the valve seat through the first flushing hole and the second flushing hole.

[0006] Furthermore, the flushing channel includes an inlet section, an installation section, and an outlet section connected in sequence. The flushing pipe is detachably connected to the inlet section, and the flushing head is detachably connected to the outlet section. The flushing head is installed in the installation section.

[0007] Furthermore, a sealing bevel is formed on the liquid separator; when the liquid separator is in the first use state, the sealing bevel abuts against the connection between the installation section and the liquid outlet section; when the liquid separator is in the second use state, the sealing bevel separates from the connection between the installation section and the liquid outlet section.

[0008] Furthermore, the dispensing component includes a dispensing head and a dispensing spring. The dispensing head is movably installed within the installation section, and the dispensing spring abuts against the dispensing head. The dispensing spring applies a force to the dispensing head to separate the dispensing head from the connection between the installation section and the outlet section.

[0009] Furthermore, a flushing groove is formed at the top of the flushing pipe, and the length of the flushing groove is less than the length of the liquid inlet section.

[0010] Furthermore, the flushing seat includes a base tube, a support plate, a bottom plate, and a base plate. The flushing channel is located inside the base tube. The support plate is connected to the side wall of the base tube. The bottom plate is connected to the support plate, and the bottom plate and the base plate are detachably connected.

[0011] Furthermore, the flushing head includes an interconnected cylindrical section and a conical section, the cylindrical section being detachably connected to the flushing channel, and the conical section being located outside the flushing channel.

[0012] Furthermore, the valve seat cleaning device also includes a top plate, with multiple flushing heads evenly arranged on the top plate, and the top plate is detachably connected to the flushing seat via guide columns.

[0013] Furthermore, the valve seat cleaning device also includes a cleaning tank, which includes a cleaning chamber and a pressurizing chamber. A flushing pipe is connected to the pressurizing chamber and extends into the cleaning chamber.

[0014] Furthermore, the pressurization chamber is connected to the cleaning chamber through a connecting hole, and a water pump is installed in the connecting hole to transport the liquid in the cleaning chamber to the rinsing chamber.

[0015] During the cleaning process of the valve seat, the flushing liquid in the flushing pipe is guided only into the flushing seat through the liquid separator. The flushing seat then flushes the inner wall of the valve seat. As the valve seat is removed from the cleaning device, the flushing liquid in the flushing pipe is guided into the flushing seat and the flushing head through the liquid separator. This facilitates flushing of the valve seat during removal, improves the surface cleanliness of the valve seat after removal, and thus improves the cleaning efficiency of the valve seat.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, as one implementation method, this application provides a valve seat cleaning device for cleaning the valve seat 1, thereby improving the cleaning efficiency of the valve seat.

[0026] The valve seat cleaning device includes a flushing pipe 2, a flushing seat 3, a flushing head 4, and a liquid distribution component 5. The valve seat 1 is placed on the flushing seat 3, and the flushing seat 3 is detachably connected to the flushing pipe 2. The flushing head 4 is detachably installed on the top of the flushing seat 3 and limits the valve seat 1 on the flushing seat 3 through the flushing head 4. The liquid distribution component 5 is installed in the flushing channel 3-1 and can move relative to the flushing channel 3-1.

[0027] Specifically, the flushing seat 3 has a flushing channel 3-1. When the valve seat 1 is cleaned by this cleaning device, the flushing pipe 2 is at least partially inserted into the flushing channel 3-1. A first flushing hole 3-2 is formed on the side wall of the flushing seat 3. The first flushing hole 3-2 is connected to the flushing channel 3-1, so that the flushing liquid is transported to the flushing channel 3-1 through the flushing pipe 2, and then the inner wall of the valve seat 1 is flushed through the first flushing hole 3-2, thereby improving the cleaning efficiency of the valve seat 1.

[0028] When the valve seat 1 is cleaned and removed from the device, the flushing pipe 2 can move relative to the flushing channel 3-1.

[0029] It should be noted that, in this embodiment, the process of removing the valve seat 1 from the valve seat cleaning device refers to the process of removing the valve seat 1 from the cleaning tank 8 along with the flushing seat 3.

[0030] like Figure 3 and Figure 4 As shown, a rinsing chamber 4-1 is formed inside the rinsing head 4, and the rinsing chamber 4-1 is connected to the rinsing channel 3-1. The rinsing head 4 has a second rinsing hole 4-2, which is connected to the rinsing chamber 4-1, so that the rinsing liquid in the rinsing channel 3-1 can be transported to the rinsing chamber 4-1, and then the outer surface of the workpiece can be rinsed through the second rinsing hole 4-2.

[0031] When the flushing pipe 2 moves relative to the flushing channel 3-1, the flushing pipe 2 will drive the liquid distribution component 5 to move relative to the flushing channel 3-1, so that the liquid distribution component 5 includes a first use state for closing the flushing chamber 4-1 and a second use state for connecting the flushing channel 3-1 and the flushing chamber 4-1.

[0032] When the liquid separator 5 is in the first use state, the liquid separator 5 closes the flushing chamber 4-1, so that the flushing liquid in the flushing pipe 2 flushes the valve seat 1 through the first flushing hole 3-2.

[0033] When the liquid separator 5 is in the second use state, the liquid separator 5 is separated from the flushing chamber 4-1, and the flushing liquid in the flushing pipe 2 flushes the valve seat 1 through the first flushing hole 3-2 and the second flushing hole 4-2.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, in one implementation, the flushing seat 3 includes a base tube 3-6, a support plate 3-7, a bottom plate 3-8, and a base plate 3-9. The flushing channel 3-1 is located inside the base tube 3-6. The support plate 3-7 is connected to the side wall of the base tube 3-6. The bottom plate 3-8 is connected to the support plate 3-7. The bottom plate 3-8 and the base plate 3-9 are detachably connected.

[0035] Among them, the base tube 3-6, the support plate 3-7, and the bottom plate 3-8 are connected to each other to form a flushing base. The flushing base 3 includes multiple flushing bases that are evenly arranged, and the multiple flushing bases that are evenly arranged are detachably installed on the base plate 3-9. The flushing base is used to limit the placement of the valve seat 1.

[0036] like Figure 6As shown, specifically, a buckle 3-10 is formed on the base plate 3-9, and the base plate 3-8 is snapped onto the base plate 3-9 through the buckle 3-10. Furthermore, a groove 3-11 is formed on the inner wall of the buckle 3-10. When the rinsing base is installed on the base plate 3-9, the support plate 3-7 is snapped into the buckle 3-10, thereby realizing the positioning and assembly of the rinsing base 3 and improving the overall strength of the rinsing base 3.

[0037] As one implementation, the flushing channel 3-1 includes an inlet section 3-3, an installation section 3-4, and an outlet section 3-5 connected in sequence. The flushing pipe 2 is detachably connected to the inlet section 3-3, and the flushing head 4 is detachably connected to the outlet section 3-5. The flushing head 4 is installed in the installation section 3-4.

[0038] The inner diameter of the outlet section 3-5 is smaller than that of the inlet section 3-3, thereby increasing the flushing fluid pressure of the outlet section 3-3, which in turn increases the flushing force of the flushing head 4 on the valve seat 1 and improves the cleanliness of the valve seat 1.

[0039] The liquid outlet section 3-5 has a two-section structure so that at least a portion of the liquid distribution component 5 can be connected to the liquid outlet section 3-5.

[0040] In one implementation, the liquid dispensing component 5 includes a dispensing head 5-2 and a dispensing spring 5-3. The dispensing head 5-2 is movably installed in the mounting section 3-4, and the dispensing spring 5-3 abuts against the dispensing head 5-2. The dispensing spring 5-3 applies a force to the dispensing head 5-2 to separate the dispensing head 5-2 from the connection between the mounting section 3-4 and the outlet section 3-5.

[0041] When the flushing pipe 2 is pulled out from the flushing channel 3-1, the liquid separator 5-2 moves downward, separating the liquid separator 5-2 from the connection between the installation section 3-4 and the outlet section 3-5, so that the outlet section 3-5 is connected to the flushing chamber 4-1. The liquid separator spring 5-3 ensures that the liquid separator 5-2 can overcome the impact force of the flushing liquid and separate the liquid separator 5-2 from the connection between the installation section 3-4 and the outlet section 3-5.

[0042] like Figure 3 As shown, in one implementation, a sealing slope 5-1 is formed on the liquid distributor 5-2; when the liquid distributor 5 is in the first use state, the sealing slope 5-1 abuts against the connection between the installation section 3-4 and the liquid outlet section 3-5; when the liquid distributor 5 is in the second use state, the sealing slope 5-1 separates from the connection between the installation section 3-4 and the liquid outlet section 3-5.

[0043] The sealing bevel 5-1 facilitates the connection between the liquid separator 5-2 and the connection between the mounting section 3-4 and the outlet section 3-5, thereby sealing the flushing chamber 4-1.

[0044] As one implementation, a slot 5-4 is formed at the bottom of the liquid separator 5-2, and the top of the flushing pipe 2 is inserted into the slot 5-4 so as to limit the position of the liquid separator 5-2 through the flushing pipe 2, preventing the liquid separator 5-2 from swinging during the movement relative to the flushing channel 3-1, so as to improve the uniformity of liquid output from the first flushing hole 3-2 of the flushing seat 3, and further improve the cleanliness of the valve seat 1 cleaned by this device.

[0045] like Figure 3 As shown, in one implementation, a flushing groove 2-1 is formed on the top side wall of the flushing pipe 2 so that the flushing liquid in the flushing pipe 2 can be transported to the flushing channel 3-1 through the flushing groove 2-1.

[0046] Specifically, the length of the rinsing tank 2-1 is less than the length of the liquid inlet section 3-3. When the rinsing pipe 2 is completely pulled out of the rinsing channel 3-1, the rinsing channel 3-1 is in a state of flow interruption to prevent the rinsing liquid from being sprayed out of the cleaning tank 8 through the rinsing channel 3-1 when the rinsing seat 3 is removed from the cleaning tank 8.

[0047] like Figure 7 As shown, as one implementation method, the valve seat cleaning device also includes a top plate 6, and multiple flushing heads 4 are evenly arranged on the top plate 6. The top plate 6 is designed so that multiple flushing heads 4 can be installed in the liquid outlet sections 3-5 at different positions, and the top surface of the valve seat 1 is limited by the flushing heads 4, thereby fixing the valve seat 1 between the flushing heads 4 and the flushing seat 3.

[0048] Furthermore, the top plate 6 is detachably connected to the flushing seat 3 via the guide post 7. The guide post 7 facilitates the positioning of the top plate 6 and the flushing seat 3, thereby improving the assembly efficiency of the flushing head 4 and the valve seat 1.

[0049] In one implementation, the flushing head 4 includes a cylindrical section 4-3 and a conical section 4-4 connected to each other. The cylindrical section 4-3 is detachably connected to the flushing channel 3-1, and the conical section 4-4 is located outside the flushing channel 3-1.

[0050] A second flushing hole 4-2 is provided on both the cylindrical section 4-3 and the conical section 4-4 to flush the inner wall and top surface of the valve seat 1 through the second flushing hole 4-2. The conical section 4-4 can be used to limit the top of the valve seat 1, so that the valve seat 1 is fixed to the flushing seat 3, preventing the valve seat 1 from shaking during the flushing process and improving the uniformity of the flushing of the valve seat 1 by this device.

[0051] Specifically, the second flushing hole 4-2 is arranged at an angle downwards, that is, the opening of the second flushing hole 4-2 located inside the flushing chamber 4-1 is higher than the opening of the second flushing hole 4-2 located outside the flushing chamber 4-1, so that the second flushing hole 4-2 flushes the surface of the valve seat 1 and improves the surface cleanliness of the valve seat 1.

[0052] like Figure 2 As shown, in one implementation, the valve seat cleaning device also includes a cleaning tank 8, which includes a cleaning chamber 8-1 and a pressurizing chamber 8-2. The flushing pipe 2 is connected to the pressurizing chamber 8-2 and extends into the cleaning chamber 8-1. The pressurizing chamber 8-2 is connected to the cleaning chamber 8-1 through a connecting hole. A water pump 9 is installed in the connecting hole to transport the liquid in the cleaning chamber 8-1 to the flushing chamber 4-1.

[0053] The cleaning fluid in the cleaning chamber 8-1 is transported to the pressurization chamber 8-2 by the water pump 9, and then the cleaning fluid is transported to the flushing channel 3-1 through the flushing pipe 2.

[0054] As one implementation, a boss 8-3 is formed inside the cleaning chamber 8-1, and a filter cotton 8-4 is provided on the top of the boss 8-3. The cleaning fluid delivered to the pressurizing chamber 8-2 is filtered through the filter cotton 8-4, thereby improving the cleanliness of the flushing fluid flowing into the pressurizing chamber 8-2 and improving the cleanliness of the flushing of the valve seat 1. Furthermore, the boss 8-3 prevents large particles of foreign matter from adhering to the filter cotton 8-4, improving the smoothness of the flushing fluid flowing through the filter cotton 8-4.

[0055] Furthermore, an ultrasonic generator is installed on the outer wall of the cleaning chamber 8-1 to generate ultrasonic waves, thereby cleaning the valve seat 1 located in the cleaning chamber 8-1.

[0056] As one implementation method, the height of the cleaning fluid in the cleaning chamber 8-1 is the same as the height of the upper end surface of the top plate 6.

[0057] The working principle of this valve seat cleaning device is as follows: First, place the valve seat 1 on the flushing seat 3, and then install the top plate 6 on the guide post 7 so that the flushing head 4 on the top plate 6 is aligned with the liquid outlet section of the flushing seat 3. The top plate 6 is then fixed on the guide post 7 by the nut, thereby fixing the valve seat 1 between the flushing seat 3 and the flushing head 4.

[0058] Then, the flushing seat 3 is installed into the cleaning tank 8, so that the flushing pipe 2 is inserted into the liquid inlet section 3-3 of the flushing seat 3. At this time, under the action of gravity, the flushing pipe 2 lifts the liquid separator 5-2, so that the flushing chamber 4-1 is closed, and the inner wall of the valve seat 1 is flushed through the first flushing hole 3-2. At the same time, the ultrasonic generator works to further clean the valve seat 1.

[0059] After the valve seat 1 is cleaned, the flushing seat 3 is removed from the cleaning tank 8. During the removal process, the distributor head 5-2 moves downward under the action of the distributor spring 5-3, causing the flushing chamber 4-1 to open. The flushing fluid simultaneously flushes the valve seat 1 through the first flushing hole 3-2 and the second flushing hole 4-2. During the lifting of the flushing seat 3, the valve seat 1 is higher than the height of the flushing fluid in the cleaning chamber 8-1, so as to facilitate the flushing of the valve seat 1 located above the flushing fluid surface. As the flushing seat 3 continues to rise, the flushing tank 2-1 is completely blocked by the inlet section 3-3, preventing the flushing fluid from spraying out of the flushing channel 3-1.

[0060] Finally, it should be noted that the above are only some preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
