[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1-12 As shown, this application provides:

[0041] An axial flow regulating valve capable of reducing mechanical wear comprises a housing 1, a buffer device 2 and an extension housing 3; the buffer device 2 is arranged inside the housing 1, and the buffer device 2 comprises a blocking block 2a, a sleeve housing 2b, a first slide groove 2c, a sliding column 2d, a pushing component 2e, a driving device 2f and a guiding component 2g; the sleeve housing 2b is arranged inside the housing 1 along the axis of the housing 1; the blocking block 2a is arranged inside the sleeve housing 2b along the axis of the sleeve housing 2b; a plurality of first slide grooves 2c are arranged, and the first slide grooves 2c are evenly inclined on the inner wall of the sleeve housing 2b; the sliding column 2 d corresponds one-to-one with the first slide groove 2c, the sliding column 2d is fixedly set on the side wall of the blocking block 2a, and the sliding column 2d slides with the first slide groove 2c; the pushing component 2e is set on one side of the blocking block 2a, and the pushing component 2e is used to push the blocking block 2a to slide in the sleeve shell 2b; the driving device 2f is set in the extension shell 3, one end of the driving device 2f is connected to the pushing component 2e, and the driving device 2f is used to drive the pushing component 2e to move; the guiding component 2g is set on one side of the pushing component 2e, and the guiding component 2g is used to guide the pushing component 2e to move stably.

[0042] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the regulating valve open without causing the driving device 2f to apply a large force due to the pressure difference on both sides of the regulating valve, thereby extending the service life of the driving device 2f. To this end, the extension shell 3 of the present application is fixedly arranged on the upper part of the casing 2b, and a first receiving groove is provided at the bottom of the extension shell 3, and a second receiving groove is provided on one side of the casing 2b along the axis of the outer shell 1, and the first receiving groove and the second receiving groove are connected to each other. The lower end of the driving device 2f is arranged in the casing 2b. The working principle of the buffer device 2 is as follows. Here, the regulating valve is taken as an example of water flow. There is a first gap between the casing 2b and the outer shell 1, so that when the water flows through the regulating valve, it will flow through the first gap between the casing 2b and the outer shell 1, and the blocking block 2a is completely in a retracted state at this time, and the blocking block 2a is completely located inside the casing 2b. At this time, the water flow in the first gap is the largest. If you want to reduce the flow rate of the water flow, the driving device 2f set in the extension shell 3 will start to start, and the driving device 2f will drive the pushing component 2e to move. The pushing component 2e pushes the blocking block 2a to slowly extend under the guidance of the guide component 2g. The outer shell 1 is a tubular structure, and the diameter of the outer shell 1 close to the blocking block 2a is smaller than the diameter of the outer shell 1 away from the blocking block 2a. The blocking block 2a is a circular columnar structure, so after the blocking block 2a is pushed out by the pushing component 2e, the water flow on the side of the outer shell 1 close to the blocking block 2a will be reduced, and as the pushing component 2e continues to push, the blocking block 2a will gradually seal the side of the outer shell 1 close to the blocking block 2a, so that the water flow in the first gap cannot flow out from the side of the outer shell 1 close to the blocking block 2a. When the driving device 2f drives the pushing component 2e to move, since the side wall of the blocking block 2a is provided with a sliding column 2d, and the sliding column 2d is slidably matched with the first slide groove 2c, when the blocking block 2a is pushed by the pushing component 2e, the sliding column 2d provided on the side wall of the blocking block 2a will slide in the first slide groove 2c, and since the first slide groove 2c is inclined, when the blocking block 2a drives the sliding column 2d provided on its upper part to move, the sliding column 2d will generate a rotational force on the blocking block 2a under the influence of the first slide groove 2c, that is, when the pushing component 2e pushes the blocking block 2a to extend out of the casing 2b, the blocking block 2a is extended and rotated at the same time. When the blocking block 2a completely blocks the side of the casing 1 close to the blocking block 2a, the water flow will be blocked by the blocking block 2a on one side of the casing 1, and at this time, since there is water flow on one side of the casing 1 and no water flow on the other side, a pressure difference will appear. If the blocking block 2a is directly retracted into the casing 2b, sufficient pulling force is required.Since the side wall of the blocking block 2a is provided with a sliding column 2d, when the push assembly 2e pulls the blocking block 2a back, the sliding column 2d provided on the blocking block 2a will slide in the first slide groove 2c, and the sliding column 2d will drive the blocking block 2a to rotate and gradually leave the side of the housing 1 close to the blocking block 2a. In this way, the force borne by the driving device 2f will not be too large, thereby protecting the driving device 2f. In this way, the technical requirement that after the regulating valve is opened, the driving device 2f will not apply a large force due to the pressure difference on both sides of the regulating valve, thereby extending the service life of the driving device 2f is achieved.

[0043] Further, such as Fig.10 As shown:

[0044] The pushing assembly 2e includes a screw rod 2e1 and a sliding block 2e2; the screw rod 2e1 is arranged inside the casing 2b along the axis of the casing 2b, and one end of the screw rod 2e1 away from the blocking block 2a is fixedly connected to the driving device 2f; the sliding block 2e2 is slidably arranged on the screw rod 2e1, and one side of the sliding block 2e2 is connected to the blocking block 2a.

[0045] Based on the above embodiments, the technical problem that the present application intends to solve is how the pushing component 2e realizes the pushing function. To this end, a guide component 2g is provided on one side of the sliding block 2e2 of the present application, and the guide component 2g can prevent the sliding block 2e2 from rotating when being driven to move by the screw rod 2e1. When it is necessary to drive the blocking block 2a to move, the driving device 2f will start to start, and the started driving device 2f will drive the screw rod 2e1 to rotate. At this time, the sliding block 2e2 set on the screw rod 2e1 will be driven by the screw rod 2e1 to slide, and the sliding block 2e2 will drive the blocking block 2a set on one side thereof to slowly extend. In this way, the pushing function of the pushing component 2e is realized.

[0046] Further, such as Figure 5-7 As shown:

[0047] The driving device 2f includes a rotary driver 2f1, a first synchronous wheel 2f2, a second synchronous wheel 2f3 and a synchronous belt 2f4; the rotary driver 2f1 is fixedly arranged on the side of the extension shell 3, and the output end of the rotary driver 2f1 is arranged horizontally; the first synchronous wheel 2f2 is fixedly arranged on the output end of the rotary driver 2f1, and the first synchronous wheel 2f2 is arranged inside the extension shell 3; the second synchronous wheel 2f3 is fixedly arranged on the end of the screw rod 2e1 away from the blocking block 2a along the axis of the screw rod 2e1; the two ends of the synchronous belt 2f4 are respectively meshed with the first synchronous wheel 2f2 and the second synchronous wheel 2f3.

[0048] Based on the above embodiments, the technical problem that the present application intends to solve is how the drive device 2f realizes the driving function. To this end, the rotary driver 2f1 of the present application is preferably a servo motor. In order to ensure the stability of transmission, the synchronous belt 2f4 is preferably a chain, the first synchronous wheel 2f2 is preferably a gear, and the second synchronous wheel 2f3 is preferably a gear. When the rotary driver 2f1 is started, the rotary driver 2f1 will drive the first synchronous wheel 2f2 set on its output end to rotate, and the first synchronous wheel 2f2 will drive the synchronous belt 2f4 to rotate, and the rotating synchronous belt 2f4 will drive the second synchronous wheel 2f3 to rotate. Since the second synchronous wheel 2f3 is fixedly connected to the screw rod 2e1, the screw rod 2e1 will be driven to rotate by the second synchronous wheel 2f3, so that the screw rod 2e1 will drive the sliding block 2e2 set thereon to slide, so that the driving function of the drive device 2f is realized.

[0049] Further, such as Fig. 9 As shown:

[0050] The pushing assembly 2e includes a guide block 2g1 and a second slide groove 2g2; at least one guide block 2g1 is provided, and the guide block 2g1 is fixedly provided on the side wall of the blocking block 2a; the second slide groove 2g2 is provided on the inner wall of the sleeve 2b, and the guide block 2g1 is slidably matched with the second slide groove 2g2.

[0051] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the sliding block 2e2 not deflect when the screw rod 2e1 drives the sliding block 2e2 to slide. To this end, the present application, when the screw rod 2e1 is driven by the driving device 2f, if the guide block 2g1 and the second slide groove 2g2 are not provided at this time, the sliding block 2e2 will rotate synchronously with the screw rod 2e1, so that the sliding block 2e2 will not slide, and the blocking block 2a cannot be pushed out. After the guide block 2g1 and the second slide groove 2g2 are provided, when the screw rod 2e1 drives the sliding block 2e2 to rotate again, since the guide block 2g1 is provided on the side wall of the sliding block 2e2, the guide block 2g1 will be restricted by the second slide groove 2g2 at this time, so that the sliding block 2e2 cannot rotate with the screw rod 2e1, so when the screw rod 2e1 rotates, the sliding block 2e2 provided on the screw rod 2e1 will be driven by the screw rod 2e1 to slide. In this way, the technical requirement that the sliding block 2e2 will not deflect when the screw rod 2e1 drives the sliding block 2e2 to slide is achieved.

[0052] Further, such as Fig. 9 and Figure 11-12 As shown:

[0053] The buffer device 2 also includes a snap-on assembly 2h, which includes an annular groove 2h1, an annular block 2h2 and a limiting and fixing assembly 2i; the annular groove 2h1 is opened along the axis of the blocking block 2a on one side of the blocking block 2a close to the sliding block 2e2; the annular block 2h2 is fixedly arranged on one end of the sliding block 2e2 close to the blocking block 2a, and the annular block 2h2 is slidably matched with the annular groove 2h1; the limiting and fixing assembly 2i is arranged on the upper part of the annular block 2h2, and the limiting and fixing assembly 2i limits the ring block 2h2 in the annular groove 2h1.

[0054] Based on the above embodiments, the technical problem that the present application wants to solve is how to make the sliding block 2e2 not affect the normal rotation of the blocking block 2a when pushing and pulling the blocking block 2a. To this end, the present application has the ring block 2h2 fixedly arranged on the sliding block 2e2, so when the screw rod 2e1 drives the sliding block 2e2 to slide, the ring block 2h2 arranged on one end of the sliding block 2e2 will rotate in the ring groove 2h1, and when the sliding block 2e2 pulls the blocking block 2a to retract into the sleeve 2b, the fixing component will restrict the ring block 2h2 in the ring groove 2h1, so that when the sliding block 2e2 is driven by the screw rod 2e1 to slide back, the sliding block 2e2 will drive the blocking block 2a to retract through the ring block 2h2 and the limiting fixing component 2i. At this time, the blocking block 2a will use the ring groove 2h1 to rotate relative to the ring block 2h2, so that the technical requirement that the sliding block 2e2 will not affect the normal rotation of the blocking block 2a when pushing and pulling the blocking block 2a is achieved.

[0055] Further, such as Fig.10 and Fig.12 As shown:

[0056] The limiting fixing component 2i includes a fixing ring 2i1, a through hole 2i2, a fixing hole 2i3 and a first screw 2i4; the fixing ring 2i1 is arranged on the side of the blocking block 2a close to the pushing component 2e along the axis of the blocking block 2a; at least one through hole 2i2 is arranged, and the through hole 2i2 is arranged on the fixing ring 2i1 through the through hole 2i2; the fixing hole 2i3 starts on one side of the blocking block 2a along the axis of the through hole 2i2; the first screw 2i4 is threadedly matched with the fixing hole 2i3.

[0057] Based on the above embodiments, the technical problem that the present application intends to solve is how the limiting fixing assembly 2i can limit the ring block 2h2 in the ring groove 2h1. To this end, the fixing ring 2i1 of the present application is detachable. When installing, it is only necessary to insert the first screw 2i4 through the through hole 2i2, and then the first screw 2i4 is threadedly engaged with the fixing hole 2i3, so that the technical requirement that the limiting fixing assembly 2i can limit the ring block 2h2 in the ring groove 2h1 is achieved.

[0058] Further, such as Figure 6 As shown:

[0059] It also includes a support frame 4; the support frame 4 is fixedly arranged on the inner wall of the casing 2b on one side of the second synchronous wheel 2f3.

[0060] Based on the above embodiment, the technical problem that the present application intends to solve is how to make the second synchronous wheel 2f3 rotate stably. To this end, the present application sets a support frame 4 so that the second synchronous wheel 2f3 can rotate more stably, so that the pushing component 2e can push the blocking block 2a more stably.

[0061] Further, such as Figure 4 As shown:

[0062] It also includes a guide block 5,

[0063] The guide block 5 is in a bullet-shaped structure and is arranged on one end of the casing 2b away from the blocking block 2a.

[0064] Based on the above embodiments, the technical problem that the present application intends to solve is how to reduce the impact force of water flow on the casing 2b. To this end, when water flows in from one end of the casing 1, the water flows in from the tip of the guide block 5. When the water flows into the guide block 5, the water flows are dispersed by the guide block 5, thereby reducing the impact force of the water flow on the casing 2b.

[0065] Further, such as Fig. 9 As shown:

[0066] It also includes a chamfer 2a1; the chamfer 2a1 is opened on the side of the blocking block 2a away from the casing 2b.

[0067] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the blocking block 2a better block the housing 1 after the blocking block 2a is pushed out by the pushed component 2e. To this end, the present application sets a chamfer 2a1 so that the blocking block 2a can fit more easily with the inside of the housing 1. In this way, the technical requirement that the blocking block 2a can better block the housing 1 after the blocking block 2a is pushed out by the pushed component 2e is achieved.

[0068] Further, such as Figure 1-12 As shown:

[0069] An assembly process of an axial flow regulating valve capable of reducing mechanical wear, applied to an axial flow regulating valve capable of reducing mechanical wear as claimed in any one of claims 1 to 9, comprises the following steps:

[0070] S1. Place the sleeve 2b provided with the blocking block 2a inside the outer shell 1; S2. Place the pushing component 2e into the sleeve 2b, and fix the pushing component 2e using the clamping component 2h and the limiting fixing component 2i; S3. Pass the extension sleeve provided with the driving device 2f through the outer shell 1 and fix it to the sleeve 2b; S4. Screw the guide block 5 on the side of the sleeve 2b away from the blocking block 2a.

[0071] Based on the above embodiments, the technical problem that the present application intends to solve is how to assemble the axial flow regulating shaft. To this end, when assembling the driving device 2f, the present application needs to weld the second synchronous wheel 2f3 to the screw rod 2e1, then sleeve the support frame 4 on the second synchronous wheel 2f3, and weld the support frame 4 to the inner wall of the housing 1, and then screw the guide block 5 into the casing 2b. At this time, the side of the guide block 5 located in the casing 2b will be connected to the side of the support frame 4 away from the screw rod 2e1, so that the second synchronous wheel 2f3 will not fall off.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
