Description

Wiring assembly and balance valve

Technical Field

The utility model relates to the technical field of valves, in particular to a wiring assembly and a balance valve.

Background

The balance valve adjusts the flow of fluid through the central bore of the valve ball by changing the position of the valve ball. The device typically consists of a controller and a sensor connected by wires. The sensor detects the flow in the pipe and transmits a signal to the controller. The controller controls the position of the valve ball according to the signal of the sensor, thereby adjusting the flow rate. The position of the valve ball is typically controlled by an electric or manual rotating device to vary the flow rate by changing the angle of the valve ball. Such devices are commonly used in heating, cooling, air conditioning systems, etc. to ensure flow balance in the pipes.

The existing balance valve controller and the sensor connected with the lead are waterproof through a sealing structure with complex design, so that water, gas and the like are prevented from entering the controller through the lead, for example, various waterproof joints are adopted at joints of the lead, the controller and the sensor, but the lead is exposed, water gas and the like can easily enter the controller through the lead, and the controller is damaged; or sealing with glue, but sealing with glue presents a drawback of difficult maintenance.

Detailed Description

In order to make the technical solutions and technical effects of the present utility model more clear, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments.

As shown in fig. 1, the balance valve in the present utility model includes a valve 1, a controller 2 fixed to the valve 1 through a connection block 5, and a sensor mount 4 connected to the controller 2 through a wire 3.

The actuator of the controller 2 is integrated with the valve stem end of the valve 1 to control the rotation angle of the valve stem, and the flow rate of the fluid passing through the central hole of the valve 1 is controlled through the angle change. The controller 2 adjusts the magnitude of the output rotation angle of the setting controller 2 with the magnitude of the sensor value in the sensor seat 4 of the control valve 1, thereby adjusting the magnitude of the flow rate through the valve 1.

As shown in fig. 2 to 4, the wiring assembly provided by the present utility model includes a wire outlet end assembly, a wire inlet end assembly, and a connection pipe 31. The two ends of the connecting pipe 31 are respectively sleeved on the circumferential outer surface of the wire outlet end assembly and the circumferential outer surface of the wire inlet end assembly. The inner diameter of the connection pipe 31 is smaller than the diameters of the wire outlet end assembly and the wire inlet end assembly, and the inner diameter of the connection pipe 31 is larger than the diameter of the wire 3.

The outgoing line end assembly comprises a first round boss 21; the incoming end assembly includes a second circular boss 41. The first round boss 21 is anastomotic and fixed with a line outlet of the controller 2; the second round boss 41 is anastomotic and fixed with the line outlet of the sensor seat 4.

The cross section of the first round boss 21 is axially provided with a wire outlet hole 212 for penetrating the wire 3; the second circular boss 41 is provided with a wire inlet hole 412 in the cross section axial direction for penetrating the wire 3.

The connection pipe 31 is a hose made of an elastic material, such as a rubber pipe or a silicone pipe. The length of the hose can be cut according to the requirements of the installation site.

The two ends of the connecting pipe 31 are respectively matched and locked with the first round boss 21 and the second round boss 41. Since the connection pipe 31 has a certain elasticity, the sealing effect in the connection pipe 31 is achieved by the elasticity of the connection pipe 31 itself. In order to ensure that the hose is locked and is not easy to fall off and the tightness is improved, a plurality of first annular protrusions 211 are circumferentially arranged on the surface of the first round boss 21 at intervals; a plurality of second annular protrusions 411 are circumferentially spaced apart from the surface of the second circular boss 41.

To further improve the sealing reliability of the connection pipe 31, a first locking member 211a is clamped on the outer surface of the connection pipe 31 contacting the first annular protrusion 211 of the first circular boss 21 to prevent the connection pipe 31 from falling off the first circular boss 21. Similarly, a second locking member 411a is clamped to the outer surface of the connection pipe 31 contacting the second annular protrusion 411 of the second circular boss 41 to prevent the connection pipe 31 from falling off the second circular boss 41. The first retaining member 211a and the second retaining member 411a may use conventional nylon ties or ties.
