Tank Valve Nozzle Head With Integrated Temperature Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tank valve devices require a fixing member to prevent relative displacement between the pipe and temperature sensor, leading to an increased number of parts.
Innovation Solution
Incorporating the temperature sensor into the nozzle head, which includes a filling line, allowing the sensor to be inserted through the nozzle head, thereby reducing the number of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensor is fixed separately from the nozzle head using a fixing member, then the temperature sensor can measure fluid temperature, but the number of parts increases
Solution Approach 1:
The temperature sensor is integrated into the nozzle head structure, merging two previously separate components (nozzle head and temperature sensor) into a single unified component. This eliminates the need for separate fixing members and reduces the total number of parts while maintaining the temperature measurement function.
Solution Approach 2:
The nozzle head is designed to serve multiple functions: it acts as both the fluid ejection component and the housing/mounting structure for the temperature sensor. This multi-functionality reduces the need for additional dedicated components for temperature measurement.
2Device complexity
If the temperature sensor is integrated into the nozzle head, then the number of parts is reduced, but the sensor may come into contact with ejected fluid
Solution Approach 1:
The nozzle head is designed with differentiated zones: a fluid ejection area and a sensor protection area. The local structure around the temperature sensor is modified to provide protection while maintaining fluid ejection functionality in other areas of the nozzle head.
Solution Approach 2:
The nozzle head structure itself acts as an intermediary barrier between the ejected fluid and the temperature sensor. By positioning the sensor within the nozzle head body rather than directly in the fluid path, the nozzle head material serves as a protective intermediary that prevents direct fluid-sensor contact.
3Stability of the object's composition
If separate fixing members are used to secure the pipe and temperature sensor, then relative displacement is prevented, but the outer diameter of the device increases
Solution Approach 1:
By merging the temperature sensor mounting function into the nozzle head, the separate fixing members are eliminated. The nozzle head itself provides the structural support and positioning, reducing the overall device envelope and outer diameter.
Solution Approach 2:
The temperature sensor is nested within the nozzle head structure, with the sensor housed inside the nozzle head body. This nested arrangement allows the sensor to be securely positioned without requiring external fixing members that would increase the outer diameter.

Function Achieved in This Case
This configuration prevents an increase in the number of parts and improves measurement accuracy by ensuring the temperature sensor is not directly contacted by ejected fluid, while maintaining ease of assembly and stable temperature measurement.

AI summary
A tank valve device has a valve block provided in an opening of a tank, a valve that is attached to the valve block, a nozzle head that extends along an axial line and is attached to the valve block and arranged inside the tank, and a temperature sensor that measures fluid temperature in the tank, and the nozzle head has a filling line that flows fluid to be filled into the tank, and the temperature sensor is inserted through the nozzle head.
