Flow Adjustment Valve Layout for Accessible Pressure Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow adjustment valves in hydraulic systems are difficult to access, making it challenging to adjust flow rates and measure pressures, especially when installed in inaccessible locations, due to the positioning of pressure measuring connections which require skilled handling and are often obstructed by the valve's design.
Innovation Solution
Rerouting at least one pressure measuring channel through the connecting piece allows for more flexible positioning of pressure measurement connections, enabling them to be placed in a more accessible area, such as the connecting piece, and using a separate insert to form part of the pressure measuring channel and hold the throttle element, facilitating easier attachment and rotation of pressure measuring sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure measuring connections are positioned directly next to the opening of the pressure measuring channel into the flow channel, then the pressure measurement is accurate, but the connections become difficult to access and require skilled handling
Solution Approach 1:
The pressure measuring channel is routed through the connecting piece at an angle (e.g., 45°) relative to the flow channel, creating a three-dimensional path that allows the pressure measuring connection to be positioned in an accessible location on the valve housing while still connecting to the pressure measurement point in the flow channel. This dimensional routing resolves the conflict between measurement accuracy and accessibility.
2Adaptability or versatility
If the flow adjustment valve is mounted in inaccessible places such as under ceilings or in shafts, then the valve does not get in the way during normal operation, but it becomes difficult to adjust the flow rate and measure pressures
Solution Approach 1:
The valve is segmented into functional components: the valve housing containing the flow channel and throttle device, the connecting piece that protrudes at an angle, and the pressure measuring connections that are routed through the connecting piece. This segmentation allows the measurement and adjustment functions to be accessed through the connecting piece while the main valve body can be installed in inaccessible locations.
3Ease of operation
If the pressure measuring channel is routed through the connecting piece, then the pressure measuring connections become more accessible, but the channel routing becomes more complex
Solution Approach 1:
The connecting piece serves multiple functions: it connects the flow channel to external piping, provides structural support, and acts as a conduit for the pressure measuring channel. By making the connecting piece multi-functional, the patent avoids adding separate components for pressure measurement routing, thereby reducing overall device complexity while improving accessibility.

AI summary
The invention relates to a flow adjustment valve (1) comprising a valve box (2) having a flow channel (3) and a connecting piece (10), disposed at an angle to the flow channel (3). A throttle unit (6) is arranged in the flow channel (3) and comprises a throttle element (8) that can be actuated through the connecting piece (10). The flow adjustment valve also comprises two measurement points (14, 15) for detecting the pressure in the flow channel (3) at both sides of a throttle arrangement, each of which measurement points is connected to a pressure measurement connection (17) via a pressure measurement channel (26, 27). The aim of the invention is to improve the design options for a flow adjustment valve of the aforementioned type. For this purpose, at least one pressure measurement channel (26) is guided through the connecting piece (10).
