Description

TECHNICAL FIELD

[0001] The present application relates to the field of heating equipment, in particular to a theftproof hot regulating valve and a regulating control method. BACKGROUND

[0002] Winter central heating is a very common winter heating method, which is generally provided by a heat unit to a community in a region through a heat source pipeline to meet the winter heating demand of the community. Because the heat source in the community is centrally supplied, some residents do not need the supply of the central heat source due to personal reasons, so the pipeline of these residents does not need to be connected during the heat source delivery process, thereby protecting the interests of the heat unit and the needs of the heat demand residents in the community.

[0003] Some residents will open the heat source pipeline connected to their own pipeline during the heating process without paying the heating fee, thereby illegally delivering the heat source, which is a great loss to the heat unit and will directly lead to the failure of the heating temperature requirement of the local floor in the community, thereby affecting the heat unit and other residents. When the heat staff checks, they directly use a bolt tool to fix the valve closed for residents who do not supply heat, but some residents will still open the valve with a tool; and because the valve in the community is large in size, the staff needs to conduct periodic large-volume inspection, thereby causing a burden problem to the maintenance task of the staff.

[0004] Therefore, based on the above problems, a theftproof hot regulating valve and a regulating control method are provided, which can ensure the stability of community heating after acting on the heat pipeline of the household, i.e., avoiding the adjustment of the heat supply of the pipeline by residents, and avoiding the problem of heat theft, to protect the effective supply of community heat source and the interests of the heat unit; at the same time, it is convenient for the heat unit to effectively manage the heat supply, so that the heat supply can meet the more scientific control requirements. SUMMARY

[0005] The present application relates to the field of heating equipment, in particular to a theftproof hot regulating valve and a regulating control method.

[0006] The present application is achieved by the following technical solutions to achieve the above-mentioned purposes: The application discloses a kind of theftproof hot regulating valves, including valve body, intercept pipeline;The intercept pipeline is arranged in the position outside the valve body, and is communicated with the valve body;Intercept end head is cooperatively arranged in the inner end position of the intercept pipeline, when the intercept end head is fixed in the inner end position of the intercept pipeline, the communication between the two ends of the valve body is hindered by the intercept end head, and the valve body is intercepted.

[0007] The intercept pipeline is arranged between the two side pipelines of the valve body, forming a cooperation position for the communication between the intercept pipeline and the two ends of the valve body, when the intercept end head cooperates with the cooperation position, the communication between the two sides of the valve body is hindered.

[0008] The intercept end head includes an intercepting part and a dismounting part. The dismounting part includes a nut end head and a shielding piece arranged outside the nut end head to shield the maximum circumferential radius of the nut. A clamping fitting is cooperatively arranged on the nut end head, and the clamping fitting is attached to the nut end head after passing through the shielding piece.

[0009] The clamping fitting includes a holding link and a clamping sleeve. The holding link is arranged below the clamping sleeve. Two arc surface sleeve plates are combined to form the clamping sleeve, and a fitting gap is left between the two arc surface sleeve plates. A shielding protrusion and a nut clamping position are arranged at the upper end of each arc surface sleeve plate. The shielding protrusion is arranged outside the nut clamping position. When the holding link is pressed towards the intercept end head, the two arc surface sleeve plates elastically deform towards the two sides, so that the shielding protrusion passes through the shielding piece on the intercept end head, and the nut end head falls into the nut clamping position.

[0010] A limiting sleeve is slidably arranged outside the clamping sleeve, and the upper end circumferential dimension of the clamping sleeve is larger than the lower end circumferential dimension. When the limiting sleeve slides to the upper end position of the clamping sleeve, the gap between the two arc surface sleeve plates is reduced by the limiting sleeve, and the distance between the two arc surface sleeve plates is limited.

[0011] A locking mechanism is arranged at the switch position of the valve body to timely lock the switch of the valve body. The locking mechanism includes a locking end head, a locking hole is arranged on the butt joint end surface of the switch, and the locking end head is cooperatively arranged with a telescopic mechanism in the locking hole. A locking groove and a sliding groove are arranged on the lower end surface of the switch. When the locking end head falls into the locking groove through the telescopic mechanism, the valve body is in a closed and locked state.

[0012] The telescopic mechanism is a spring telescopic component, and the locking end is made of magnetic material. The spring telescopic component is disposed in the locking hole, and the locking end presses against the spring telescopic component for setting. A magnetic key is provided in conjunction with the switch component. The magnetic key cooperates with the switch component, and a switch magnet is provided on the contact end face of the magnetic key and the switch component. The lower magnetic pole of the switch magnet is opposite to the upper magnetic pole of the locking end.

[0013] A filter structure is installed inside the intercepting pipe. When the filter structure is inserted into the mating position, it completely fills the inside of the intercepting pipe.

[0014] The lower end of the rotating shaft of the valve body is connected to a drive motor, and the drive motor is connected to the community control system through data transmission, and the community control system controls the drive motor.

[0015] A method for regulating and controlling an anti-theft thermal regulating valve includes the following steps: S1, During the non-heating season, the staff uses the snap-fit ​​sleeve to install the shut-off end into the mating position to achieve the shut-off operation of the fluid on both sides of the valve body; S2, When the heating season arrives, the staff will use the snap-fit ​​sleeve to remove the cut-off end from the mating position and install the filter structure into the cut-off pipe to achieve fluid communication on both sides of the valve body and conduct a heat test operation of the heating system. S3. After the heating system has completed the trial heating operation, the staff will selectively open and close the switches according to the heating information provided by the residents, and lock the switches of the residents who do not select heating using a magnetic key. S4. When a resident needs to operate the heating system, the staff will use a magnetic key to unlock the closure of the nose tip so that the resident can achieve the heating effect. S5, after the heating season ends, the staff will install the shut-off end into the mating position using the snap-fit ​​sleeve to cut off the flow of fluid on both sides of the valve body, thereby completing the adjustment operation of the heating for the year.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Because traditional community heating valves are relatively easy to operate, many residents tend to adjust or open / close them without authorization.

[0017] This device is designed with a valve body and a corresponding flow-stopping pipe. The flow-stopping pipe, in turn, is equipped with a flow-stopping end. This end directly connects to both ends of the valve body for flow control. Due to the unique structure of the flow-stopping end, it cannot be disassembled by ordinary users using conventional tools, making it easier for staff to control. Furthermore, to facilitate disassembly, the device includes a snap-fit ​​fitting. This fitting allows for easy removal of the flow-stopping end from its mating position, preventing issues caused by unconventional installation methods that hinder disassembly.

[0018] This device differs from traditional switches in its design. While anyone can easily turn a traditional switch on and off, this device incorporates a locking mechanism to lock the switch in a secure position, preventing residents from operating it unauthorizedly. Furthermore, a magnetic key is integrated into the locking mechanism, facilitating easy access for staff to control the switch and achieve optimal management. Attached Figure Description

DETAILED DESCRIPTION

[0031] The present application will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not used to limit the scope of the present application. In addition, it should be understood that after reading the content taught by the present application, those skilled in the art can make various modifications or changes to the present application, and these equivalent forms also fall within the scope defined by the present application.

[0032] At present, the following problems may occur in the centralized heating in the community: 1. Some residents will open the heat source pipeline connected to their own pipeline during the heating process without paying the heating cost, which will cause a great loss to the heat supply unit and directly lead to the failure of the heating temperature requirement of the local floor in the community, thereby affecting the heat supply unit and other residents.

[0033] 2. When the heat supply staff checks, they will directly use a bolt tool to fix the valve closed by the residents who do not supply heat, but some residents will still open the valve with tools; and because the valve in the community is large in size, the staff needs to check periodically in large quantities, thereby causing the maintenance task of the staff to be also a burden.

[0034] Therefore, in view of the above technical problems, a kind of anti-theft heat regulating valve is set: The utility model relates to a valve body 1, cut -off pipeline 2;The cut -off pipeline 2 is arranged at the outside position of valve body 1 and is communicated with valve body 1;The cut -off end head 3 is arranged at the inner end position of cut -off pipeline 2, when the cut -off end head 3 is fixed at the inner end position of cut -off pipeline 2, the cut -off end head 3 prevents the communication between the two ends of valve body 1, and the cut -off of valve body 1 is carried out. Figure 3 As shown in the drawings, after the cut -off pipeline 2 is arranged in the pipeline of the two sides of valve body 1, the fluid at one end of valve body 1 needs to pass through the cooperation position 4 formed by the cut -off end head 3 and valve body 1, and then flow out from the other end of valve body 1;Therefore, after the cooperation position 4 is hindered by the cooperation of the cut -off end head 3, the normal flow of the fluid between the two sides of valve body 1 can be cut off, thereby leaving more space for the disassembly and installation of the cut -off end head 3 for the staff.

[0035] Because the cut -off end head 3 needs to be protected from being easily disassembled, it cannot be disassembled relative to the cooperation position 4 using conventional tools, so the specific structure of the cut -off end head 3 is as follows: The cut -off end head 3 includes a cut -off part 5 and a disassembly part 6;The disassembly part 6 includes a nut end head 7 and a shielding piece 8, the shielding piece 8 is arranged at the outside position of the nut end head 7, and the maximum circumferential radius of the nut is shielded;The nut end head 7 is provided with a clamping piece, and the clamping piece is in contact with the nut end head 7 after passing through the shielding piece 8. Figure 5 As shown in the drawings, the shielding piece 8 is arranged at the outside position of the nut end head 7, so that the maximum radius of the nut end head 7 is shielded by the shielding piece 8, when the resident wants to disassemble the cut -off end head 3 privately, the resident needs to hold the nut end head 7 with tools in the narrow space of the cut -off pipeline 2, and apply enough force to the nut end head 7 to realize the disassembly of the nut end head 7, which is not realistic for conventional tools. The clamping fitting comprises a holding link 9 and a clamping sleeve 10; the holding link 9 is arranged below the clamping sleeve 10; two arc-surface sleeve plates 11 are combined to form the clamping sleeve 10, and a fitting gap 12 is left between the two arc-surface sleeve plates 11; a shielding protrusion 13 and a nut clamping position 14 are arranged at the upper end of each arc-surface sleeve plate 11, and the shielding protrusion 13 is arranged outside the nut clamping position 14; when the holding link 9 is pressed towards the cutoff end head 3, the two arc-surface sleeve plates 11 elastically deform towards the two sides, so that the shielding protrusion 13 passes through the shielding piece 8 on the cutoff end head 3, and the nut end head 7 falls into the nut clamping position 14. Because the traditional dismounting tool cannot easily extend into the cutoff pipeline 2 and effectively clamp and dismount the nut end head 7, the clamping sleeve 10 is arranged as two arc-surface sleeve plates 11, and the shielding protrusion 13 and the nut clamping position 14 are arranged at the upper end of the arc-surface sleeve plate 11; metal material is selected for the arrangement of the clamping sleeve 10; when the clamping sleeve 10 is subjected to a force towards the shielding piece 8, the shielding protrusion 13 passes through the shielding piece 8, so that the nut clamping position 14 cooperates with the nut end head 7; in this case, the clamping sleeve 10 can be rotated, and the cutoff end head 3 is removed from the cooperation position 4 under the action of the force. Most importantly, the clamping sleeve 10 is arranged as two arc-surface sleeve plates 11, which needs to pay attention to two problems: first, the shielding protrusion 13 needs to smoothly pass through the shielding piece 8; second, the nut clamping position 14 needs to effectively cooperate with the nut end head 7. Therefore, after the two arc-surface sleeve plates 11 are arranged, the fitting gap 12 between the two arc-surface sleeve plates 11 can provide space for the shielding protrusion 13 to smoothly pass through the shielding piece 8.

[0036] As for the cooperation of the nut clamping position 14 with the nut end head 7, a limiting sleeve 15 is arranged outside the clamping sleeve 10, and the upper end circumference of the clamping sleeve 10 is larger than the lower end circumference; when the limiting sleeve 15 is slid to the upper end of the clamping sleeve 10, the limiting sleeve 15 reduces the gap between the two arc-surface sleeve plates 11 and limits the distance between the two arc-surface sleeve plates 11. After the limiting sleeve 15 is arranged, the limiting sleeve 15 can limit and lock the upper end of the two arc-surface sleeve plates 11, so that the nut clamping position 14 can effectively fit with the nut end head 7, thereby stably dismounting the cutoff end head 3 from the cooperation position 4 when the clamping sleeve 10 is rotated. After the cutoff end head 3 is dismounted, the limiting sleeve 15 is slid downward to reduce the limitation of the distance between the upper ends of the two arc-surface sleeve plates 11, so as to facilitate the workers to easily remove the cutoff end head 3 from the upper ends of the two arc-surface sleeve plates 11.

[0037] Through the above technical problems, some households in the process of community central heating will privately adjust the opening and closing of the valve body 1, because some households will open the switch of the valve body 1 without paying the community heating fee, and the operation is relatively simple. Therefore, in view of this problem, the following improvements are made to the structure of the valve body 1: The locking mechanism is provided at the position of the switch piece 16 of the valve body 1, and the locking mechanism is used to lock the switch piece 16 of the valve body 1 in time; the locking mechanism includes a locking end 17, a locking hole 18 is provided on the butt joint end face of the switch piece 16, and the locking end 17 is matched with the extension mechanism and arranged in the locking hole 18; a locking groove 19 and a sliding groove 20 are arranged on the lower end face of the switch piece 16, and when the locking end 17 falls into the locking groove 19 through the extension mechanism, the valve body 1 is in a closed and locked state. As shown in the description Figure 7 The locking end 17 is set by matching the extension mechanism, so as to realize the closing and locking requirement of the switch piece 16. Through the control of the extension mechanism, the extension and retraction operation of the locking end 17 relative to the locking hole 18 can be controlled. When the locking end 17 falls into the locking groove 19 arranged on the lower end face of the switch piece 16 under the control of the extension mechanism, the valve body 1 is in a closed state, and because the locking end 17 falls into the locking groove 19, the normal rotation of the locking end 17 and the switch piece 16 is limited, so that the switch piece 16 cannot be normally rotated by the household in this state, thereby achieving the effect that the household cannot privately open and close the switch valve body 1; when the locking end 17 falls into the sliding groove 20 arranged on the lower end face of the switch piece 16, the locking end 17 can move in the sliding groove 20 relative to the position when the switch piece 16 rotates, so that the rotation operation of the switch piece 16 can be easily realized by the worker in this state.

[0038] In order to realize the above effect, it is necessary to ensure the effective control of the extension mechanism, so the extension mechanism is specifically structured as follows: The telescopic mechanism is a spring telescopic piece 21, the locking end head 17 is made of magnet material, the spring telescopic piece 21 is arranged in the locking hole 18, and the locking end head 17 holds the spring telescopic piece 21; the switch piece 16 is matched with a magnetic key 22, the magnetic key 22 is matched with the switch piece 16, a switch magnet 23 is arranged on the contact end face of the magnetic key 22 and the switch piece 16, and the lower end magnetic pole of the switch magnet 23 is opposite to the upper end magnetic pole of the locking end head 17. When the magnetic key 22 is arranged by being attached to the switch piece 16, because the switch magnet 23 of the magnetic key 22 is attached to the end face magnetic pole opposite to the locking end head 17, the locking end head 17 is pushed into the locking groove 19 under the action of magnetic force, so that the switch piece 16 can be rotated in this state. When the switch key is removed from the position of the switch piece 16, the locking end head 17 is pushed out of the locking hole 18 under the action of the spring telescopic piece 21, so that the locking end head 17 falls into the locking groove 19 or the fixed groove. The worker can control the locking end head 17 to fall into the sliding groove 20 or the locking groove 19 according to the rotation angle of the valve body 1, so as to loosen the opening and closing of the switch piece 16, and the resident cannot open the switch piece 16 with tools, so as to avoid the problem that the resident opens and closes the switch piece 16 privately.

[0039] The above structure is further provided and optimized as follows: A filter screen structure is arranged in the intercepting pipeline 2, and the filter screen structure fills the inside of the intercepting pipeline 2 when the filter screen structure is inserted into the matching position 4. By arranging the filter screen structure, the fluid impurities in the valve body 1 delivered to the resident heating system can be reduced, so that the problem of blockage of the heating system for a long time is avoided.

[0040] The lower end of the rotation shaft of the valve body 1 is connected with a driving motor, and the driving motor is connected with a community control system through data transmission and is driven by the community control system.

[0041] A regulating control method of a theftproof heating regulating valve, comprising the following steps: S1, in the non-heating season, the worker installs and arranges the intercepting end head 3 to the matching position 4 by the clamping sleeve 10, so as to realize the intercepting operation of the fluid on both sides of the valve body 1; S2, when the heating season arrives, the worker removes the intercepting end head 3 from the matching position 4 by the clamping sleeve 10, and arranges the filter screen structure in the intercepting pipeline 2, so as to realize the fluid communication on both sides of the valve body 1 and the trial heating operation of the heating system; S3, when the heating system completes the test heating operation, the staff according to the heating information provided by the household, switch 16 selective opening and closing, and through the magnetic key 22 will not select the heating switch 16 of the household closed lock; S4, when a household needs to be heated operation, the staff through the magnetic key 22 will open the nose tip of the closed lock state, so that the household to achieve the heating effect; S5, when the heating season ends, the staff through the card sleeve 10 will install the cutting end 3 to the matching position 4 position, realize the cutting operation of the fluid on both sides of the valve body 1, so as to complete the annual heating adjustment operation.

[0042] Therefore, the setting of the anti-theft heating regulating valve and the adjusting control method can ensure the stability of community heating after acting on the heating pipeline into the house, that is, to avoid the private adjustment of the pipeline heat source supply by the household, and to avoid the problem of heat stealing, so as to protect the effective supply of community heat source and the interests of heat supply unit; At the same time, it is convenient for the heat supply unit to effectively manage the heat supply, so that the heat supply can meet the more scientific control requirements.
