Description

Technical Field

[0001] This application relates to the field of balancing valve technology, specifically to a novel insertion-type balancing valve. Background Technology

[0002] Insert-type balancing valves, also known as cartridge-type balancing valves, are modular cartridge-type balancing valves. They mainly consist of a cylindrical valve body and a block-shaped valve block. During assembly, the valve body is simply screwed into the cartridge hole of the valve block and secured by threads or retaining rings, eliminating the need for external piping connections. Insert-type balancing valves are characterized by their compact structure, being directly integrated inside the valve block, saving space and reducing potential leakage points.

[0003] Threaded connections improve the installation efficiency of the valve body, but when the valve block is assembled on mobile equipment such as excavators, long-term vibration can easily cause the threads to loosen, thereby reducing the reliability of the connection between the valve body and the valve block and affecting the normal operation of the valve body. Utility Model Content

[0004] In order to overcome the problem that the valve body is prone to loosening due to vibration in the prior art, this application provides a novel insertion-type balancing valve.

[0005] This application adopts the following technical solution: a novel insert-type balance valve, including a valve block and a valve body. The valve block has an insertion hole on its side wall. The valve body is inserted into the insertion hole and connected to the insertion hole by a thread. A pair of clamping blocks are also movably provided on the side wall of the valve block. The clamping blocks can only move radially along the valve body. The pair of clamping blocks are respectively and correspondingly provided on both sides of the valve body. The clamping blocks have a slot on the side facing the valve body. When the pair of clamping blocks are in contact with each other, the pair of slots are adapted to be engaged on the outside of the valve body.

[0006] Optionally, a pair of dovetail grooves are symmetrically provided on the side wall of the valve block and on both sides of the valve body. One end of the dovetail groove is connected to the other side wall of the valve body, and the other end of the dovetail groove is close to the insertion hole.

[0007] The dovetail groove is equipped with a slider, the lower outer wall of the slider is in contact with the inner wall of the dovetail groove, and the upper part of the slider is connected to the clamping block.

[0008] Optionally, the inner diameter of the dovetail groove gradually increases from top to bottom.

[0009] Optionally, the upper part of the valve body is provided with an adjusting nut, which is located outside the insertion hole, and the shape of the two slots after they are closed is consistent with the shape of the adjusting nut.

[0010] Optionally, each of the pair of clamps is provided with at least two magnets on opposite sides, and when the pair of clamps are close to each other, the magnets can attract each other.

[0011] Optionally, each of the two slots has a sliding opening and an adjustment opening at the bottom. The top of the sliding opening is connected to the top of the clamping block. The inner diameter of the sliding opening gradually decreases from top to bottom along the width direction of the dovetail groove. The bottom of the sliding opening is connected to the top of the adjustment opening. The inner diameter of the adjustment opening gradually decreases from top to bottom along the length direction of the dovetail groove.

[0012] A pressure rod is provided between the pair of clamping blocks. One end of the pressure rod is located in one of the sliding openings, and the other end of the pressure rod is located in the other sliding opening. The length of the pressure rod is less than the maximum distance between the two adjustment openings and greater than the minimum distance between the two adjustment openings.

[0013] Optionally, the outer diameter of the pressure rod is less than or equal to the inner diameter of the adjustment port along the width direction of the dovetail groove.

[0014] Optionally, the connection between the adjustment port and the sliding port is provided with an elastic protrusion, and the distance between a pair of elastic protrusions is less than the outer diameter of the pressure rod.

[0015] Compared with the prior art, this application achieves the clamping effect of the adjusting nut by the attraction between the two clamping blocks. That is, the rotation of the adjusting nut is restricted by the locking action of the two slots, thereby ensuring that the valve body will not loosen due to external vibration, and improving the connection reliability between the valve body and the valve block.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1-5 As shown, a novel insert-type balancing valve includes a valve block 1 and a valve body 2. The valve block 1 is generally rectangular and has an insertion hole 11 on its side wall. The insertion hole 11 is a threaded hole. The valve body 2 is cylindrical and has an adjusting nut 20 on its upper part. An external thread is provided on the outer wall of the valve body 2 below the adjusting nut 20. After inserting the valve body 2 into the insertion hole 11, the valve body 2 can be screwed into the insertion hole 11 by rotating the adjusting nut 20. The external thread on the valve body 2 is reliably matched with the internal thread of the insertion hole 11, realizing the quick installation of the valve body 2.

[0024] Two dovetail grooves 12 are provided on the side wall of the valve block 1 where the insertion hole 11 is opened. The two dovetail grooves 12 are symmetrically arranged on both sides of the insertion hole 11. One end of the dovetail groove 12 is connected to the other side wall of the valve body 2, and the other end of the dovetail groove 12 is close to the insertion hole 11. A slider 13 is adaptedly provided in the dovetail groove 12. The inner diameter of the dovetail groove 12 gradually increases from top to bottom. The lower outer wall of the slider 13 fits against the inner wall of the dovetail groove 12. In this way, the slider 13 can reliably slide in the dovetail groove 12 and cannot slide down from the dovetail groove 12 in the vertical direction. The upper part of the slider 13 is located outside the dovetail groove 12, and a clamping block 3 is provided on the upper part of the slider 13. Two clamping blocks 3 are respectively and correspondingly provided on both sides of the valve body 2. The clamping block 3 has a slot 31 on the side facing the valve body 2. When the clamping block 3 is pushed to move closer to the valve body 2, the slider 13 can slide smoothly in the dovetail groove 12, thereby improving the stability of the movement of the clamping block 3. The adjusting nut 20 is located outside the insertion hole 11. When a pair of clamping blocks 3 are fitted together, the slot 31 on the clamping block 3 will fit with the outer wall of the adjusting nut 20. That is to say, the shape of the two slots 31 after docking is consistent with the shape of the adjusting nut 20, both being hexagonal. The clamping block 3 can only move and cannot rotate under the cooperation of the slider 13 and the dovetail groove 12, thereby ensuring that the valve body 2 will not loosen due to external vibration after installation. Furthermore, a marking line can be set on both the side wall of the valve block 1 and the adjusting nut 20. When the two marking lines coincide, it indicates that the adjusting nut 20 is turned in place, and the clamping block 3 can be reliably clamped on the outside of the adjusting nut 20, thereby achieving the effect of preventing loosening.

[0025] Each pair of clamping blocks 3 has at least two magnets 32 on one side opposite to each other. When the pair of clamping blocks 3 approach each other, the magnets 32 can attract each other, thus realizing the automatic attraction between the two clamping blocks 3 and preventing the two clamping blocks 3 from automatically disengaging, effectively improving the clamping reliability of the clamping blocks 3 on the adjusting nut 20.

[0026] Each pair of slots 31 has a sliding opening 33 and an adjusting opening 34 at its bottom. The top of the sliding opening 33 communicates with the top of the clamping block 3. An elastic protrusion 36 is provided at the connection between the adjusting opening 34 and the sliding opening 33. The distance between the pair of elastic protrusions 36 is less than the outer diameter of the pressure rod 35. The sliding opening 33 gradually decreases in diameter from top to bottom along the width direction of the dovetail groove 12. The bottom of the sliding opening 33 communicates with the top of the adjusting opening 34. The adjusting opening 34 gradually decreases in diameter from top to bottom along the length direction of the dovetail groove 12. A pressure rod 35 is provided between the pair of clamping blocks 3. One end of the pressure rod 35 is located in one of the sliding openings 33, and the other end is located in the other sliding opening 33. The length of the pressure rod 35 is less than the maximum distance between the two adjusting openings 34 and greater than the minimum distance between the two adjusting openings 34. The outer diameter of the pressure rod 35 is less than or equal to the inner diameter of the adjusting opening 34 along the width direction of the dovetail groove 12.

[0027] The maximum inner diameter of the sliding opening 33 is larger than the outer diameter of the pressure rod 35, allowing the pressure rod 35 to be quickly inserted into the sliding opening 33 and slide to the junction of the sliding opening 33 and the adjustment port 34. At this time, pressing the pressure rod 35 downward will squeeze the elastic protrusion 36 and cause the elastic protrusion 36 to deform. In this way, the pressure rod 35 can enter the adjustment port 34 from the sliding opening 33 under the action of external force. Similarly, if the pressure rod 35 needs to be moved from the adjustment port 34 to the sliding opening 33, it is still under the assistance of external force. When the pressure rod 35 enters the adjustment port 34, the inner diameter of the adjustment port 34 gradually decreases along the length of the dovetail groove 12, causing the distance between the two adjustment ports 34 to gradually decrease from top to bottom. Since the length of the pressure rod 35 is greater than the minimum distance between the two adjustment ports 34, the two clamping blocks 3 will separate from each other after the pressure rod 35 is pressed down. In other words, by pressing down on the pressure rod 35, the attraction of the magnets 32 on the two clamping blocks 3 is broken, and the two clamping blocks 3 are manually separated, so that the adjusting nut 20 can be exposed, making it easy to disassemble the valve body 2.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
