Problems solved by technology

However, with the widespread use of static balance valves, its shortcomings are gradually exposed. First of all, static balance valves cannot achieve the effect of dynamic balance valves, and cannot automatically adjust when the hydraulic system of the pipeline fluctuates.
When the system is stable and there are few fluctuations, the static balance valve can maximize its value. For example, it is used in the central heating system in the north; secondly, the debugging problem of the static balance valve in the process of operation, the general hydraulic system will have multiple supports. Each branch introduces water flow from the inlet of a main pipe, and then returns to the outlet of the main branch pipe. The debugging of static balancing valves in complex piping systems has always been a very complicated task, often requiring many times. Repeated debugging, resulting in a lot of waste of heat and material resources

Embodiment 1

[0035] The debugging method of this static balance valve is used to debug all the branches in the hydraulic system are connected in parallel, starting from a water inlet pipeline and returning to the balance valve of the same return water pipeline, so that the flow ratio of all the balance valves in the system Both are equal to 1.

[0036] Step A. Select the standpipe with the largest flow ratio:

[0037] Fully open all balance valves, automatic valves, and normally on / off valves, adjust the main balance valve, control the pump flow rate to be between 100% and 110% of the design flow rate, determine the design flow rate of all standpipe 1, and measure the flow rate of all standpipe 1 Actual flow, and calculate the flow ratio of each standpipe 1: flow ratio = actual flow / design flow, select the standpipe 1 with the largest flow ratio;

[0038] Step B. Select the branch pipe with the maximum flow ratio:

[0039] Determine the design flow rate of all branch pipes 2 on the selec...

Embodiment 2

[0056] The structure and principle of this embodiment are basically the same as that of Embodiment 1, except that the branch pipe in this embodiment includes a branch balance valve V, four end devices 1, 2, 3, 4 and four end balance valves V 1 , V 2 , V 3 , V 4 , adopt the same debugging method as in embodiment 1 to adjust the hydraulic system, and finally make the flow ratios of all balance valves equal to 1.

Embodiment 3

[0058] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that the branch pipe in this embodiment includes a branch balance valve V, eight terminal devices 1, 2, 3, 4, 5, 6, 7, 8 and eight end balance valves V 1 , V 2 , V 3 , V 4 , V 5 , V 6 , V 7 , V 8 , adopt the same debugging method as in embodiment 1 to adjust the hydraulic system, and finally make the flow ratios of all balance valves equal to 1.

Abstract

The invention provides a debugging method of a static balance valve and belongs to the technical field of hydraulic systems. The debugging method of the static balance valve solves the problems that the prior static balance valve is low in debugging efficiency and the like, and comprises the following steps: A selecting a maximum flow ratio stand pipe; B selecting a maximum flow ratio branch pipe; C selecting a minimum flow ratio terminal unit; D adjusting a terminal balance valve on terminal unit; E adjusting terminal balance valves on all terminal units on the maximum flow ratio stand pipe; F adjusting branch balance valves of all branch pipes on the maximum flow ratio stand pipe; G adjusting stand balance valves of all stand pipes; repeting the steps mentioned above and finally adjusting the flow ratio of a main balance valve of the hydraulic system to be one, flow ratios of all other balance valves are accordingly to be one. The debugging method of the static balance valve has the advantages of being high in debugging success rate, debugging efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of hydraulic systems and relates to a debugging method of a static balance valve. Background technique [0002] Static balance valve is also known as balance valve, manual balance valve, digital lock balance valve, two-position control valve, etc. It changes the flow resistance flowing through the valve by changing the gap (opening) between the valve core and the valve seat to achieve regulation. The purpose of the flow is the resistance of the system. The static balance valve can balance the new water volume according to the proportion calculated by the design. Each branch can be increased or decreased in proportion at the same time, which can meet the flow demand of the partial load under the current climate demand. Play the role of heat balance. [0003] Due to its good regulating characteristics and low price, the static balance valve has been widely used in various hydraulic systems. However, with the...
