[0002] With the rapid development of my country's industry, the harsh working conditions in various industries have increasingly stringent requirements on valves. Ultra-high pressure differential working conditions such as oil and gas fields, coal chemical industry, and non-ferrous metal smelting are emerging in an endless stream. The working pressure difference is high, the medium flow rate is fast, and the scouring is severe. Conventional materials such as metal and PTFE cannot meet the working conditions. The harsh working conditions have put forward higher requirements on valve performance. Conventional valves are damaged and offline in a very short time on site. The prior art also has ceramic valves with longer service life under extreme working conditions, but general ceramic valves only have a longer service life than conventional metal valves due to the particularity of their materials. The service life of such ceramic valves cannot meet the expectations of users under extreme working conditions, and the development of valve technology in the prior art is relatively mature, and it is impossible to make better improvements in materials. Therefore, it is necessary to make corresponding improvements to the existing ceramic valves to extend the service life of ceramic valves under long-term scouring of high-speed media. Summary of the invention

[0003] The object of the present invention is to provide a multi-stage impact regulating switch ceramic valve to solve the problems in the prior art.

DETAILED DESCRIPTION

[0021] 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.

[0022] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments. Example

[0023] like Figures 1 to 5 As shown, the present invention provides a multi-stage impact regulating switch ceramic valve, including a mounting tube 1, in which a primary buffer component 2, a secondary buffer component 3 and a ball valve component 4 for regulating the water output in the mounting tube 1 are arranged in sequence along the medium flow direction, an adjusting component 5 for regulating the medium flow size is arranged on the top of the secondary buffer component 3, and a tertiary buffer component 6 is fixedly installed in the ball valve component 4.

[0024] As a further scheme of an embodiment of a multi-stage impact regulating switch ceramic valve, the secondary buffer assembly 3 includes an inner lining sleeve 31 fixedly installed in the mounting tube 1, a throttling sleeve 32 is fixedly connected to the inner lining sleeve 31, a transfer sleeve 33 is installed in the throttling sleeve 32, and the transfer sleeve 33 is connected to the interior of the primary buffer assembly 2, a plurality of water outlet holes 331 are opened on the wall of the transfer sleeve 33, a plurality of receiving holes 321 are opened on the wall of the throttling sleeve 32, and the plurality of water outlet holes 331 and the plurality of receiving holes 321 are staggered with each other, a water outlet 311 is opened at the bottom of the wall of the inner lining sleeve 31, and the water outlet 311 is connected to the interior of the tertiary buffer assembly 6.

[0025] As a further illustration of the embodiments of the present invention, there are ceramic valves with longer service life under extreme working conditions in the prior art, but generally ceramic valves have a longer service life than conventional metal valves only because of the particularity of their materials, and the service life of such ceramic valves still cannot meet the expectations of users under extreme working conditions, and the development of valve technology in the prior art is relatively mature, and it is impossible to make better improvements in materials. Therefore, in order to protect the ceramic valve, it is necessary to adjust the flow in the pipeline at an appropriate time, and cooperate with a buffer structure with an impact offset function to extend the service life of the ceramic valve, so that the ceramic valve can also have a longer service life under extreme working conditions. In this embodiment, by arranging a first-level buffer component 2, a second-level buffer component 3 and a third-level buffer component 6 in the mounting pipe 1 to buffer the medium flowing in the pipeline in turn, it is avoided that the medium flow rate is too fast to cause continuous scouring of the inner wall of the mounting pipe 1. Specifically, the lining sleeve 31 provides a stable support structure for the entire second-level buffer component 3, and also plays a role in protecting the inner wall of the mounting pipe 1. After the medium flowing out of the primary buffer assembly 2 enters the transfer sleeve 33 and rushes out along the water outlet 331, since the water outlet 331 and the receiving hole 321 are staggered with each other, the medium gushing out from the water outlet 331 directly impacts the wall of the throttling sleeve 32 to achieve a buffering effect, so that the flow rate of the medium is reduced and evenly dispersed into the annular space between the transfer sleeve 33, the throttling sleeve 32 and the liner sleeve 31. The multiple receiving holes 321 on the throttling sleeve 32 restrict and guide the flow of the medium, so that the medium forms a complex flow state in the annular space inside the throttling sleeve 32 and the liner sleeve 31, further reducing the flow rate and pressure fluctuation of the medium. This structure can effectively balance the pressure of the medium in different directions and reduce the wear of components caused by excessive local pressure. For example, when conveying a liquid medium containing solid particles, the secondary buffer assembly 3 can prevent the particles from scratching and damaging the inside of the valve due to high-speed impact, ensuring the long-term stable operation of the valve, thereby extending the service life of the valve. In addition, above the secondary buffer component 3, there is an adjusting component 5 for adjusting the flow rate of the medium in the pipeline, which is used to control the overall flow rate of the medium in the pipeline, and cooperate with the ball valve component 4 to control the open or closed state in the pipeline, so that the medium flow in the entire pipeline becomes controllable, and then under extreme working conditions, the pipeline can be protected by adjusting the medium flow rate or closing the pipeline, thereby further extending the service life of the pipeline.

[0026] As a further scheme of an embodiment of a multi-stage impact regulating switch ceramic valve, the regulating component 5 includes a placing plate 51 fixedly mounted on the outer wall of the mounting tube 1, a cylinder 52 is fixedly mounted on the placing plate 51, and the output end of the cylinder 52 is downwardly arranged, a blocking rod 53 is fixedly connected to the output end of the cylinder 52, and the blocking rod 53 extends into the transfer sleeve 33, the blocking rod 53 is slidably connected to the transfer sleeve 33, and the blocking rod 53 is used to block the top of the transfer sleeve 33.

[0027] As a further explanation of the embodiment of the present invention, in this embodiment, when it is necessary to adjust the medium flow, the cylinder 52 is started, and the output end of the cylinder 52 drives the blocking rod 53 to move up and down along the vertical direction of the transfer sleeve 33. When the blocking rod 53 is extended into the transfer sleeve 33, the outer wall of the blocking rod 53 fits with the inner wall of the transfer sleeve 33, and the water outlet holes 331 on the transfer sleeve 33 are blocked by the blocking rod 53. As the blocking rod 53 extends more, the water outlet holes 331 are blocked more, and the channel for the medium in the transfer sleeve 33 to flow out is reduced, thereby achieving the effect of adjusting the water output of the secondary buffer component 3.

[0028] As a further solution of an embodiment of a multi-stage impact regulating switch ceramic valve, the transfer sleeve 33 is rotatably installed in the throttling sleeve 32, a spiral groove 332 is opened on the inner wall of the transfer sleeve 33, a limiting ball 54 is fixedly installed on the side wall of the blocking rod 53, and the limiting ball 54 is slidably installed in the spiral groove 332.

[0029] As a further explanation of an embodiment of the present invention, in this embodiment, the limiting ball 54 is fixedly connected to the blocking rod 53 and slides along the spiral groove 332. Therefore, when the blocking rod 53 moves up and down in the vertical direction of the transfer sleeve 33, the limiting ball 54 slides along the spiral groove 332, and the transfer sleeve 33 is restricted by the throttling sleeve 32 and cannot move up and down, so the transfer sleeve 33 can only rotate in place. As a further solution of this embodiment, the number of limiting balls 54 is set to two or more, and multiple limiting balls 54 are slidably installed in the spiral groove 332 to improve the stability of the transfer sleeve 33 during rotation. After the transfer sleeve 33 rotates to a preset angle, the outlet hole 331 on its outer wall is connected to the receiving hole 321. In this connected state, the medium flows out from the outlet hole 331 and no longer impacts the inner wall of the throttling sleeve 32, so that the medium outflow rate is accelerated, thereby achieving the effect of flushing the scale in the receiving hole 321. The blocking rod 53 can also drive the transfer sleeve 33 to rotate again to a preset angle so that the outlet hole 331 and the receiving hole 321 are misaligned again, so that the present invention can meet more usage requirements and has a wider range of application scenarios. In addition, when the limiting ball 54 in the present invention slides along the spiral groove 332, the limiting ball 54 scrapes off the dirt attached to the spiral groove 332 by rubbing against the groove wall of the spiral groove 332, thereby improving the cleanliness of the spiral groove 332.

[0030] As a further embodiment of a multi-stage impact regulating switch ceramic valve, the ball valve assembly 4 includes a valve seat 41 fixedly installed in the mounting tube 1, a ball 42 is rotatably connected in the valve seat 41, a through hole 421 is opened in the ball 42 for the medium to pass through, an actuator 43 is fixedly installed on the placement plate 51, and the output end of the actuator 43 is fixedly connected to the ball 42, when the ball 42 rotates to a preset angle, the liner sleeve 31 is connected to the interior of the ball 42.

[0031] As a further explanation of an embodiment of the present invention, in this embodiment, after the medium flows out from the inner lining sleeve 31, it can flow out along the preset direction of the mounting pipe 1 through the perforation 421 in the ball 42, and the ball 42 is driven by the actuator 43 to offset the perforation 421 to offset the inner lining sleeve 31. The arc surface of the ball 42 cooperates with the valve seat 41 to temporarily block the mounting pipe 1, so that the medium in the mounting pipe 1 stops flowing, thereby controlling the opening and closing state of the entire mounting pipe 1.

[0032] As a further solution of an embodiment of a multi-stage impact regulating switch ceramic valve, the three-stage buffer assembly 6 includes a cross rod 61 fixedly installed in the through hole 421, a fan blade group 62 is rotatably installed on the cross rod 61, and a baffle 63 is fixedly installed in the end of the through hole 421 away from the liner sleeve 31.

[0033] As a further illustration of an embodiment of the present invention, in this embodiment, when the medium passes through the perforation 421, when the medium flow rate in the sphere 42 is lower than the horizontal bisector of the perforation 421, the medium below the horizontal line impacts the blades on the blade group 62, and the blade group 62 impacted by the medium rotates to relieve the impact force of the medium. In the process of the medium continuously impacting the blade group 62, the blade group 62 rotates axially along the cross bar 61, and the impact force of the medium is continuously relieved while rotating. When the blade group 62 rotates to the bottom of the perforation 421, the entire section of the medium flow is cut off and moved along the installation through the cooperation between the blades and the hole wall of the perforation 421. The mounting tube 1 is pushed out in a preset direction to avoid excessive medium gushing out from the inner liner sleeve 31, so that the medium continuously scours the inner wall of the perforation 421 to form wear, and a baffle 63 for intercepting the medium is provided at the end of the perforation 421 to buffer and intercept the small stream of medium pushed out by the fan blades again, so that the medium flows out of the mounting tube 1 relatively smoothly. When the medium flow in the sphere 42 is higher than the horizontal line of the perforation 421, the medium simultaneously impacts the upper and lower ends of the fan blade group 62, so that the fan blade group 62 cannot rotate in a single direction, and can only produce a slight reciprocating swing due to the impact of the medium, and this swing can alleviate the impact force of the medium to form a buffering effect.

[0034] As a further solution of an embodiment of a multi-stage impact regulating switch ceramic valve, a transverse partition 64 for dividing the medium is fixedly installed in the end of the through hole 421 close to one end of the liner sleeve 31.

[0035] As a further explanation of an embodiment of the present invention, in this embodiment, the flow rate of the medium in the pipeline exceeds the horizontal line of the perforation 421. By setting a cross partition 64, the medium exceeding the horizontal line in the perforation 421 can be better divided, so that the medium impacting the fan blade group 62 is separated up and down, which is convenient for balancing the force of the fan blade group 62 to achieve the effect of swing buffering.

[0036] As a further scheme of an embodiment of a multi-stage impact regulating switch ceramic valve, the first-stage buffer assembly 2 includes a ceramic tube 21 fixedly installed in the mounting tube 1, the top of the ceramic tube 21 is fixedly connected to the bottom of the throttling sleeve 32, a water inlet hole 22 is opened on the tube wall of the ceramic tube 21, an inclined hole 23 is opened at the end of the mounting tube 1, and the inclined hole 23 is connected to the water inlet hole 22.

[0037] As a further illustration of the embodiment of the present invention, in this embodiment, the special design of the inclined hole 23 at the end of the mounting tube 1 and the water inlet hole 22 on the ceramic tube 21 guides the medium to flow into the ceramic tube 21 at a specific angle, thereby avoiding local high pressure caused by direct impact of the medium. The change in the tube diameter inside the ceramic tube 21 and the friction of the tube wall gradually reduce the flow rate of the medium, converting kinetic energy into heat energy, and effectively weakening the initial impact force of the medium.
