Description

Technical Field

[0001] The utility model belongs to the technical field of automatic flow regulating devices for heating pipe networks, and in particular relates to an automatic flow regulating device for heating pipe networks. Background Art

[0002] The automatic flow regulating device for heating pipe network is mainly used in heating pipe network system. It uses the medium's own pressure to control the main valve core opening, stabilizes the outlet flow at the set value, and keeps the outlet flow unchanged when the inlet pressure is unstable. It is used on pipelines that need to control flow. It consists of main valve, flow regulator, needle valve, pilot valve, ball valve, pressure gauge and other parts.

[0003] The existing automatic flow regulating device for the heating pipe network is installed on the heating pipe network to automatically adjust the pressure in the pipe network at all times to ensure that its flow rate is always in a stable value state, but it has the following defects:

[0004] (1) When the existing automatic flow regulating device for heating pipe network is in use, the regulator structure used for the initial adjustment of the medium flow pressure is adjusted by rotating the handle, but the handle is directly exposed to the outside world, which is prone to accidental contact and misoperation, resulting in the handle rotating and misadjusting the pressure, reducing the accuracy and stability of the medium flow in the heating pipe network. For this reason, we propose an automatic flow regulating device for heating pipe network. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic flow regulating device for a heating network, so as to solve the problem that the handle of the automatic flow regulating device proposed in the above-mentioned background technology is directly exposed to the outside world, which is prone to accidental contact and misoperation, resulting in the handle rotating and misadjusting the pressure, thereby reducing the accurate and stable flow of the medium in the heating network.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic flow regulating device for a heating pipe network, comprising a flow regulating valve body, a flow regulating valve body is provided with a flow regulator assembly, a movable sleeve is provided on the outside of one end of the flow regulator assembly, a top spring is provided between the top of the flow regulator assembly and the movable sleeve, and the top spring is located inside the movable sleeve, a synchronization column is fixed at the center of the inner end surface of the movable sleeve, a synchronization groove is provided at the center of the end surface of the flow regulator assembly, one end of the synchronization column is inserted into the synchronization groove, and a handle is installed on the top of the movable sleeve.

[0007] Preferably, a limiting groove with a circular cross-section is provided on the outer wall of the flow regulator assembly, a limiting block is provided on the inner side of the limiting groove, and the limiting block is fixed on the inner wall of the movable sleeve.

[0008] Preferably, the longitudinal sections of the synchronization groove and the synchronization column are both square structures, and the central axes of the synchronization column and the synchronization groove coincide with each other.

[0009] Preferably, the end surface of the synchronization column is provided with a bevel.

[0010] Preferably, a spherical groove is formed on the end surface of the limit block, and a ball is embedded in the spherical groove.

[0011] Preferably, the cross-section of the movable sleeve is a circular structure.

[0012] Preferably, a guide column is provided on the inner side of the top spring, and the guide column is fixed on the inner end surface of the movable sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The movable sleeve is mounted on the outer wall of the flow regulator assembly by means of the designed movable sleeve, top spring, synchronous column and synchronous groove. When the water pressure of the valve body needs to be adjusted, the hand holds the handle and presses the movable sleeve downward so that one end of the synchronous column is inserted into the synchronous groove with the same rectangular cross-section. The flow regulator assembly can be driven to rotate by the handle. After the adjustment is completed, the pressing of the movable sleeve is stopped, and the top spring in the compressed state pushes the movable sleeve to move so that the end of the synchronous column is disengaged from the synchronous groove. At this time, the movable sleeve is at the outer wall of the end of the flow regulator assembly and is free to rotate, thereby ensuring that the flow regulator assembly will not rotate and change the flow accuracy of the utility model when the hand accidentally touches the handle and causes misrotation. The movable sleeve is limited by the designed limit block and limit groove to prevent it from falling off the flow regulator assembly. The designed ball plays a lubricating role to reduce the wear between the limit block and the inner wall of the limit groove. The designed guide column limits the top spring to prevent the top spring from being compressed and bent excessively and changing its shape and losing elasticity. BRIEF DESCRIPTION OF THE DRAWINGS
