Besides blocking caused by unclean medium, the welding slag, scrap iron and the like in the pipeline can also cause blocking, so that the pipeline has to have a better anti-blocking function, but no non-blocking valve is available at present, and the anti-blocking function can only be improved from various aspects.
In order to make the valve have anti-blocking effect, most of the prior art valves adopt a simple method for changing the flow path type of the valve, but taking a single seat valve as an example, after medium flows into the valve from the horizontal direction, the medium flows out horizontally again by vertical throttling. It can be seen that the complex flow path with reverse turning can generate a plurality of vortex dead zones, and provides a precipitable space for the medium, so the complex flow path is extremely easy to block; from the cooperation of sleeve and valve plug, the clearance between the two is little, slightly unclean thing can cause the card to block up. Looking at the old single-seat valve and double-seat valve, the guiding position of the lower upper cover is a dead zone for medium precipitation. The deposited objects are easy to be accumulated continuously, so that the valve core is difficult to move downwards, and the blocking phenomenon such as the valve is not closed in place occurs. The anti-blocking effect of such valves is not significant and such anti-blocking valves have no versatility and intelligence.
In the prior art, only one method for removing and replacing the blocked valve is time-consuming and labor-consuming, and the valve blockage can only be found when the valve is opened or closed or after equipment connected with the valve fails, even if the valve is removed and replaced at the moment, the service life of the equipment and the production speed of a factory are also adversely affected, and the equipment is damaged, so that the maintenance cost is greatly increased.

The first sealing body and the valve body second sealing body not only have sealing function, but also play a role in supporting the rotary sealing sleeve; the two are in surface-to-surface contact commonly known as surface contact; the rotary sealing sleeve can realize the sealing of the valve body by rotation, so that the sealing effect of the surface contact is better than that of the linear sealing, and the rotary sealing sleeve is more wear-resistant; and the surface contact is bigger than the line contact, so that the first sealing body and the second sealing body can better play a role in supporting the rotary sealing sleeve.
The valve body 1 is provided with a leakage-proof protection cover 13 at a position corresponding to the extension of the valve rod, and sealing filler is filled between the leakage-proof protection cover 13 and the valve body 1. A cavity is formed between the leakage-proof protective cover 13 and the valve body 1, and the cavity is filled with sealing filler; at this time, the sealing filler can block the gap at the joint of the connecting rod and the valve body, so that the sealing effect is achieved, and the sealing filler can be rubber with good waterproof sealing effect.
The valve rod 6 and the rotary sealing sleeve 4 are both provided with a U-shaped sealing ring 14 for sealing at the joint with the valve body. Because the valve rod and the rotary sealing sleeve can rotate frequently, the U-shaped sealing ring 14 can also play a good role in sealing during rotation; the U-shaped sealing ring arranged at the joint of the valve rod and the valve body and the sealing filler in the anti-leakage protection cover form secondary sealing, the U-shaped sealing ring at the joint of the rotary sealing sleeve and the valve body forms secondary sealing, and the integral sealing effect of the device is greatly enhanced.

The reason for designing the opening and the through opening is to ensure the sealing effect of the valve body and the rotary sealing sleeve and simultaneously make the anti-blocking unit work better; when the anti-blocking unit works, the opening on the rotary sealing sleeve is aligned with the through hole on the valve body, meanwhile, the through hole on the first sealing body is aligned with the through hole on the second sealing body, and the anti-blocking piece extends into the valve cavity to start working; when the anti-blocking unit stops working, after the anti-blocking piece is retracted, the anti-blocking unit is detached to clean, the rotary sealing sleeve can be rotated to a proper position, at the moment, the opening on the rotary sealing sleeve is staggered with the through opening on the valve body, meanwhile, the through opening on the first sealing body is staggered with the through opening on the second sealing body, and the first sealing body and the second sealing body form a sealing structure, so that the anti-blocking unit can be unscrewed to clean; the anti-blocking unit connected through the threads can be conveniently taken down while the tightness is ensured.
And a circular sealing ring 51 is arranged at the joint of the anti-blocking unit 5 and the rotary sealing sleeve 4.
The anti-blocking unit 5 further comprises a baffle 15 arranged in the middle of the connecting rod, an O-shaped sealing ring 17 arranged at the joint of the connecting rod 21 and the sealing shell, and a rubber protection pad 16 arranged at the tail end of the anti-blocking piece 11. The baffle 15 can prevent the blockage from entering deeper into the sealed shell when the anti-blockage unit is taken down, so that the anti-blockage unit is cleaned conveniently. The rubber protection pad can prevent the anti-blocking piece from damaging the inner wall of the valve cavity, so that the blocking object accumulation caused by the damage of the inner wall of the valve cavity is avoided.
The anti-blocking piece 11 is a filter basket with interception forks; the anti-blocking member is provided with a flow sensor connected to the driving unit by a wire installed in the connecting rod 21.
The anti-blocking member 11 may be of the structure shown in fig. 4, or may be a filter basket with other blocking forks; under the condition that normal circulation of liquid is guaranteed, the liquid can be filtered by the filter basket, and blockage caused by impurity deposition is prevented, but the blocking capacity of the filter basket to linear blockage is very poor, at the moment, the linear blockage is blocked by the blocking fork which is of a short rod structure and is arranged on the outer surface of the filter basket; therefore, the filter basket with the interception fork not only can increase the contact area of the anti-blocking piece and the liquid and effectively intercept impurities, but also is beneficial to intercepting linear blocking objects in the liquid, such as fine wires and tiny hairs, and prevents the linear blocking objects from blocking the valve. The filter basket may be an existing cylindrical filter basket such as that available from kunya wire mesh products limited.
If the anti-blocking valve is used for connecting a water pipe, the anti-blocking member can also be made of a filtering basket made of Cu-Ni-Zn ternary alloy, and the anti-scaling and anti-corrosion mechanism and experimental study of alloy materials disclosed in the university of Harbin university of industry, 2009, records the materials, and can effectively prevent scale from blocking the valve.
The sealing element 18 is installed at the joint of the driving unit 12 and the sealing shell, and the sealing element 18 can be made of rubber materials.
The drive unit 5 comprises a control module and an actuator for controlling the radial movement of the connecting rod 21 along the sealed enclosure 10; the control module is connected with an alarm lamp 19 and a flow sensor for monitoring flow change in the valve cavity; the control module comprises a singlechip for processing flow information and a SIM communication module for sending alarm information to the mobile phone. The actuator may use a servo-actuated cylinder.
The singlechip model can adopt a C51 series singlechip or a 430 series singlechip, and the singlechip has strong function, small volume and low power consumption and can be well arranged in the driving unit.
The SIM communication module can be directly connected with the singlechip, and is powered by the singlechip; the SIM communication module is used for sending monitoring or alarm information to the mobile phone of the user, and no matter where the user is, the user can give an instruction to an operator after receiving the information, so that the mobile phone is very convenient. The adoption of the singlechip and the SIM communication module realizes the intellectualization of the anti-blocking valve, can perform real-time man-machine interaction, is convenient and practical, protects equipment of a factory in real time, and greatly reduces the damage probability of the equipment.
When the anti-blocking unit 5 works, the servo electric cylinder pushes the connecting rod to drive the anti-blocking piece to extend into the valve cavity of the valve body, the flow sensor starts working, monitors the liquid flow information in the valve body and feeds back the liquid flow information to the singlechip in time, and the singlechip processes and judges whether blocking accumulation occurs in the valve cavity;
if the blocking objects are accumulated, the blocking objects are proved to intercept or adsorb enough blocking objects, at the moment, if the blocking objects are not replaced recently, the blocking objects can start to block the valve, at the moment, the servo electric cylinder temporarily does not drive the blocking objects to return to the original position, the blocking prevention unit immediately sends a short message to a mobile phone of a user through the SIM communication module, and meanwhile, the alarm lamp flashes to alarm to remind the user to replace the standby blocking prevention unit; if the user sends a short message response in time, stopping sending the short message, and starting to reset the anti-blocking part through the servo electric cylinder; if the user does not respond later, the alarm lamp continuously flashes and continuously sends a short message to the user for alarming, and meanwhile, the control module drives the servo electric cylinder to drive the anti-blocking member to return more slowly through weak current, so that the blocking object is prevented from being accumulated in an accelerating way.
The valve is not required to be closed when the anti-blocking unit is replaced, the sealing performance and the safety of the valve are guaranteed while the normal operation of the valve is not affected, the anti-blocking unit can be replaced quickly, the replaced anti-blocking unit can be reused after being cleaned, waste is avoided, and the use cost is saved.
The invention prevents the valve from being blocked by using a method of interception and filtration, and the valve cavity of the valve body is in a circular shape communicated with the pipeline, thereby avoiding the occurrence of vortex dead zones and medium precipitation dead zones to the greatest extent; the anti-blocking valve is not only free from adding any other substances into the liquid flowing through the valve, but also can perform anti-blocking operation without changing the substance attribute of the liquid, has a simple structure, has a size and a specification which are basically the same as those of a common valve, can be widely applied to the existing factories and families, does not need to perform pipeline replacement operation, and greatly saves the installation cost and the installation time.
The anti-blocking unit of the anti-blocking valve can be replaced at any time, the valve body can be sealed by rotating the rotary sealing sleeve under the condition that the valve is opened or closed without wheels, then the anti-blocking unit is taken down for replacement, and the installed anti-blocking unit is quite simple to replace; therefore, the problem of equipment damage caused by valve blockage is avoided from the source, the service life of the equipment is prolonged, and the production speed of a factory is not influenced.
