Description

Technical Field

[0001] The utility model relates to the technical field of temperature regulating devices, and in particular to a temperature balancing regulating device for a heating pipe network. Background Art

[0002] The temperature balance and regulation devices of the existing heating pipe network are key equipment used to maintain and regulate the distribution of heat energy in the heating system. The main purpose of these devices is to ensure that the heat energy is evenly distributed to each user according to the design requirements while maintaining the stability and efficiency of the system.

[0003] At present, the balancing valve is a common temperature balancing and regulating device for the heating pipeline network. The balancing valve can ensure that each branch loop obtains the flow specified by the design and prevents some loops from having too much or too little flow. This can avoid overheating in some areas and overcooling in other areas, and achieve temperature balance in the entire system. The balancing valve is composed of a valve body, a valve core, and an adjusting handwheel. When adjusting the balancing valve, the staff needs to turn the adjusting handwheel. After the adjustment, since the adjusting handwheel cannot be locked, there is a risk of the adjusting handwheel turning due to accidental touch or other reasons, thereby causing the adjustment state of the balancing valve to change, and the stability of the entire system cannot be guaranteed. Utility Model Content

[0004] The utility model provides a temperature balancing and regulating device for a heating pipe network, which can lock a regulating hand wheel, thereby achieving the purpose of preventing the regulating state of a balancing valve from being changed arbitrarily and ensuring the stability and safety of the device.

[0005] To this end, the present application provides a temperature balance regulating device for a heating pipe network, and the technical solution adopted is as follows:

[0006] The device comprises a valve body, an adjusting hand wheel is provided on the valve body, a limiting mechanism is arranged between the valve body and the adjusting hand wheel; the limiting mechanism comprises a slide groove, a limiting rod, a rotating disk and a mounting block; wherein, the slide groove is arranged on the side wall of the adjusting hand wheel, one end of the limiting rod is inserted into the slide groove, a spring is also provided inside the slide groove, and two ends of the spring are respectively fixed to the slide groove and the limiting rod; the rotating disk can be rotatably sleeved between the valve body and the adjusting hand wheel, a limiting hole is arranged on the rotating disk; the other end of the limiting rod can be inserted into the limiting hole.

[0007] The mounting block is fixed on the valve body, and a mounting groove is provided on the top thereof. A threaded hole is provided on the mounting groove, and a limiting screw matching the thread is passed through the threaded hole. The rotating disk is inserted into the mounting groove and can be tightened and locked by the limiting screw.

[0008] A further technical solution is that a built-in groove is opened on the side wall of the slide groove, and a built-in plate is fixed to one end of the limit rod inserted into the slide groove, and the built-in plate is inserted into the built-in groove and can slide relative to the built-in groove.

[0009] A further technical solution is that the outer sleeve of the valve body is provided with a mounting ring slidably connected thereto, a connecting groove is opened on the mounting block, a fixing block is fixed on the mounting ring, and the fixing block can be inserted into the connecting groove.

[0010] A further technical solution is that a buckle is buckled on the upper part of the mounting ring, a threaded rod and a nut matching the threaded rod are passed through the buckle, and the buckle fixes the mounting ring on the valve body by tightening the nut.

[0011] The working principle and beneficial effects of this application are:

[0012] 1. By setting the limit rod and cooperating with the limit hole, when the limit rod is adjusted by the adjusting handwheel, the limit hole is moved to the bottom of the limit rod by rotating the rotating disk, and the limit rod is inserted into the inside of the limit hole, and the rotating disk is fixed by the limit screw. At this time, the position of the adjusting handwheel is completely locked to prevent it from being rotated again due to other reasons such as misoperation, thereby ensuring that the adjustment state of the balancing valve is not changed arbitrarily and ensuring the stability and safety of the device.

[0013] 2. By setting a connecting groove, cooperating with the mounting ring and the fixing block, pushing the mounting ring and the fixing block to release the connection between the mounting ring and the connecting groove, and then pulling the mounting block to release the connection between the mounting block and the rotating disk, the mounting block is disassembled at this time, thereby realizing the detachability of the mounting block and facilitating the replacement of the mounting block.

[0014] 3. The mounting ring is fixed to the valve body by setting a buckle, cooperating with a threaded rod and a nut, thereby increasing the stability of the connection between the mounting ring, the mounting block and the valve body. BRIEF DESCRIPTION OF THE DRAWINGS
