Therefore, the dynamic adjusting valve 100 can be conveniently cleaned, the cleaning difficulty is reduced, the labor cost is saved, and the practicability of the dynamic adjusting valve 100 is improved.

For example, referring to fig. 1 to 3, the dynamic adjustment valve 100 includes a valve body 1, the valve body 1 is formed with an inlet chamber 11, a mounting chamber 12, and an outlet chamber 13, the inlet chamber 11, the mounting chamber 12, and the outlet chamber 13 are sequentially communicated, and the inlet chamber 11 and the outlet chamber 13 are respectively communicated with external pipes so that a working fluid (typically water) can flow into the valve body 1 from the inlet chamber 11 and flow out of the valve body 1 from the outlet chamber 13.

The dynamic regulator 100 further includes a flow balance assembly 2, the flow balance assembly 2 including a regulator cartridge 21, the regulator cartridge 21 being movably disposed within the mounting cavity 12. Part of the outer peripheral wall of the regulating cylinder 21 is arranged at a distance from the inner peripheral wall of the mounting cavity 12, so that the regulating cylinder 21 and the inner peripheral wall of the mounting cavity 12 can jointly define the regulating cavity 14, a flow channel cavity 211 is defined in the regulating cylinder 21, and two ends of the flow channel cavity 211 are respectively communicated with the inlet cavity 11 and the outlet cavity 13, so that working fluid in the inlet cavity 11 can flow into the outlet cavity 13 through the flow channel cavity 211. It should be noted that, the flow area between the outlet chamber 13 and the flow channel chamber 211 is adjustable, and the preset flow of the dynamic adjustment valve 100, which is the flow in the outlet chamber 13, can be adjusted by adjusting the flow area between the outlet chamber 13 and the flow channel chamber 211.

Meanwhile, an inflow gap 15 may be formed between the other end of the adjusting cylinder 21 and the valve body 1, the inflow gap 15 is communicated between the inlet chamber 11 and the flow channel chamber 211, and when the adjusting cylinder 21 moves relative to the valve body 1, the flow area of the inflow gap 15 will be changed accordingly to adjust the flow and pressure in the flow channel chamber 211. The flow balance assembly 2 further comprises a regulating piece 22 and an elastic piece 23, wherein the regulating piece 22 is sleeved and connected on the outer side of the regulating cylinder 21, and the regulating piece 22 divides the regulating cavity 14 into a first cavity 141 and a second cavity 142 with variable volumes. The first chamber 42 is located at a side of the adjusting member 22 away from the inflow gap 15 and is in communication with the flow channel chamber 211, so that the pressure in the first chamber 141 can push the adjusting plate 22 to move towards the direction of reducing the inflow gap 15, the second chamber 142 is located at a side of the adjusting member 22 close to the inflow gap 15 and is in communication with the outlet chamber 13, and the pressure in the second chamber 142 can push the adjusting plate 22 to move towards the direction of increasing the inflow gap 15.

Specifically, when the flow rate in the inlet chamber 11 is equal to the preset flow rate, the flow rates of the flow channel chamber 211 and the outlet chamber 13 are equal, and the pressure difference between the flow channel chamber 211 and the outlet chamber 13 is zero; when the flow in the inlet cavity 11 increases, the flow flowing into the flow channel cavity 211 correspondingly increases, the pressure in the flow channel cavity 211 is larger than the pressure in the outlet cavity 13 due to the limitation of the overflow area, a pressure difference is formed between the first cavity 141 and the second cavity 142, the pressure in the first cavity 141 can push the regulating piece 22 to drive the regulating cylinder 21 to move downwards along the axial direction of the regulating piece so as to reduce the inflow gap 15, the flow flowing into the flow channel cavity 211 from the inlet cavity 11 can be reduced, the pressure in the flow channel cavity 211 can be reduced, the pressure difference is regulated, and the flow in the outlet cavity 13 is further constant; when the flow in the inlet chamber 11 is reduced, the flow flowing into the flow channel chamber 211 is correspondingly reduced, the pressure in the flow channel chamber 211 is smaller than the pressure in the outlet chamber 13, a pressure difference is formed between the first chamber 141 and the second chamber 142, the pressure in the second chamber 142 can push the regulating plate 22 to drive the regulating cylinder 21 to move upwards along the axial direction of the regulating plate so as to increase the inflow gap 15, the flow of the inlet chamber 11 into the flow channel chamber 211 can be increased, the pressure in the flow channel chamber 211 can be increased, the pressure difference is regulated, and then the flow in the outlet chamber 13 is constant.

It should be noted that, because the flow rate of the second chamber 142 is smaller, impurities are easy to precipitate in the second chamber 142, and the second chamber 142 is located inside the dynamic adjustment valve 100, so that the second chamber 142 is difficult to clean. To the above-mentioned problem, the dynamic control valve 100 further includes a drain member 4, a drain outlet 17 is disposed on the valve body 1, the drain outlet 17 is communicated with the second cavity 142, the drain member 4 is detachably mounted at the drain outlet 17, so that the working fluid in the second cavity 142 can flow to the drain member 4, the drain member 4 can adsorb or precipitate impurities in the working fluid (such as an adsorption material disposed in the drain member 4 or a structure in which the drain member 4 is configured to be prone to precipitate impurities, which is not limited in this application), and then the drain member 4 is detached from the valve body 1, and a new drain member 4 or a cleaned drain member 4 is mounted in the drain outlet 17, thereby completing the cleaning of the second cavity 142. Thus, the difficulty in cleaning the dynamic adjustment valve 100 can be reduced, which is beneficial to saving the labor cost.

It should be noted that, the pollution discharging member 4 may be screwed to the valve body 1, snapped to the valve body, or may be any detachable connection, which is not limited in the present utility model.

According to the dynamic adjusting valve 100 of the embodiment of the utility model, the dirt discharging member 4 is detachably arranged in the dirt discharging outlet 17 of the valve body 1, so that impurities in the second cavity 142 can be precipitated or adsorbed in the dirt discharging member 4, and then the dirt discharging member 4 with the impurities is detached from the valve body 1 for cleaning or replacement, so that the dynamic adjusting valve 100 can be cleaned conveniently, the cleaning difficulty is reduced, the labor cost is saved, and the practicability of the dynamic adjusting valve 100 is improved.

In some embodiments of the utility model, the drain 4 comprises a body portion 41 and a head portion 42 connected, the body portion 41 being adapted to be removably mounted within the drain 17 and defining a settling chamber 411, the settling chamber 411 being in communication with the second chamber 142.

For example, referring to fig. 2 to 3, the drain 4 includes a main body 41 and a head 42, the head 42 is connected to one end of the main body 41, and the main body 41 is disposed to match the drain 17 such that the main body 41 is detachably mounted in the drain 17. The main body 41 defines a sedimentation chamber 411, one end of the sedimentation chamber 411 facing away from the head 42 is open outwards, the sedimentation chamber 411 is used for being communicated with the second chamber 142, so that working fluid in the second chamber 142 can flow into the sedimentation chamber 411, impurities in the working fluid flowing into the second chamber 142 can be deposited in the sedimentation chamber 411, and cleaning and replacement of the sewage disposal member 4 can be achieved by detaching the sewage disposal member 4 from the valve body 1.

Through the arrangement, the cleaning efficiency of the dynamic adjusting valve 100 can be improved, the pollution discharge piece 4 can be repeatedly utilized, the cost is reduced, and the practicability of the dynamic adjusting valve 100 is improved.

In some embodiments of the present utility model, as shown in fig. 3, the settling chamber 411 may be configured in a column shape. Through the arrangement, the precipitation amount can be directly judged according to the thickness of the precipitated impurities, the working state of the dynamic regulating valve 100 can be monitored by combining the precipitation time, and when the precipitation amount is too large, the pollution discharge piece 4 with larger volume can be timely replaced or faults are eliminated, so that the reliability of the dynamic regulating valve 100 is improved.

In a practical arrangement, the sedimentation chamber 411 adopts a set volume v=sh, where s is a bottom area, H is a height, and time t elapses, and if the sedimentation thickness of the internal impurity is H, the impurity volume is sH can be calculated according to the impurity thickness H, and the remaining space in the sedimentation chamber 411 is equal to sH-sH, i.e., the flow space of the working fluid is sH-sH. According to the above data, the caliber parameter of the dynamic adjusting valve 100 is correspondingly adjusted, for example, the volume of the sedimentation chamber 411 is increased, so as to improve the anti-blocking performance of the dynamic adjusting valve 100. It should be emphasized that the flow path of the working fluid is most likely to be blocked at the settling chamber 411, which can most serve as a reference for the critical value of the blocking of the dynamic adjustment valve 100, and can serve as a basis for monitoring the feedback of the dynamic adjustment valve 100 data by the dynamic adjustment valve 100.

It should be noted that, the drain member 4 is preferably disposed at the inflection point where the back pressure hole 16 and the second chamber 142 meet, so that it is designed because impurities are most likely to accumulate at the inflection point and are difficult to clean. By the arrangement, the working fluid flowing into or out of the second cavity 142 needs to flow through the sedimentation cavity 411, so that the cleaning effect of the sewage disposal member 4 on the second cavity 142 can be improved, and the reliability of the dynamic adjusting valve 100 can be improved.

In some embodiments of the present utility model, as shown in fig. 2, the height position of the back pressure hole 16 and the height position of the second chamber 142 may be set to be larger than the height position of the settling chamber 411. Through the above arrangement, the flow rate of the working fluid can be reduced in the process of flowing out of the sedimentation cavity 411, so that impurities in the working fluid are easier to sediment into the sedimentation cavity 411, impurities in the sedimentation cavity 411 are not easy to flow out, and the reliability of the dynamic adjusting valve 100 is improved.

For example, referring to fig. 3, the diaphragm 43 may be provided to extend obliquely in the radial direction of the settling chamber 411 in the axial direction of the settling chamber 411 toward the direction approaching the open mouth; alternatively, the diaphragm 43 may be provided to extend obliquely in the radial direction of the settling chamber 411 in the axial direction of the settling chamber 411 in a direction away from the open mouth, which is not limited in this application.

In a practical arrangement, the spacer 43 may be disposed on the side of the inner peripheral wall of the settling chamber 411 away from the back pressure hole 16, and the spacer 43 is configured to extend obliquely in the radial direction of the settling chamber 411 in the direction toward the direction close to the opening along the axial direction of the settling chamber 411, so that the settling effect of the drain 4 on the impurities carried by the working fluid flowing toward the second chamber 142 can be improved, and the settled impurities can be effectively prevented from flowing into the second chamber 142 with the working fluid, and the cleaning effect of the drain 4 on the second chamber 142 is improved. With the above arrangement, the reliability of the dynamic adjustment valve 100 is improved.
