Pinch Valve Housing With Guided Sliding Cover Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pinch valve housings with sliding lids face challenges in safety and manageability, including high force absorption, difficulty in precise reclosure, risk of misalignment, and space requirements for hose insertion and removal.
Innovation Solution
A valve housing design incorporating a sliding lid with a hinge-like articulation, featuring longitudinally extending guide edges and grooves, and a bolt-sleeve mechanism that allows for axial and rotational movement, enabling secure closure and easy hose insertion/removal while preventing mechanical separation from the housing body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding cover is used to securely close the pinch valve, then safety and force distribution are improved, but handling and reclosure precision deteriorate
Solution Approach 1:
A guide element with guide edge and guide groove creates an intermediary guiding mechanism between the cover and housing body. The guide edge of the cover engages with the guide groove in the housing body, providing precise alignment and positioning during reclosure operations, thereby improving handling precision without compromising the secure closure provided by the sliding cover design.
2Stability of the object's composition
If the guide edges engage tightly in the cover guide grooves to prevent play, then closure stability is improved, but insertion difficulty increases
Solution Approach 1:
The guide groove is segmented into a first guide groove portion and a second guide groove portion with different orientations. The first portion receives the guide edge at an angle to facilitate easy insertion, while the second portion provides tight engagement perpendicular to the guide edge to ensure closure stability. This segmentation allows the same structure to provide both easy insertion and stable closure.
3Reliability
If a conventional sliding cover is used, then force distribution is improved, but space requirements for hose insertion increase
Solution Approach 1:
The cover is designed with dynamic positioning capability through the guide element mechanism. The cover can be positioned in multiple locations: fully closed position for secure closure with force distribution, and partially open position for hose insertion/removal. This dynamic positioning allows the sliding cover to maintain its force distribution advantages while reducing the space required for hose operations compared to complete removal requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances safety by distributing normal forces uniformly and simplifies hose handling by allowing precise alignment and reduced space requirements for opening and closing, ensuring secure and efficient operation of the pinch valve.
Implementation Method 1
The guide edges (210) of the cover (200) are slidingly mounted on the housing body (100) by engaging the cover guide grooves (120) of the latter with one another
Implementation Method 2
the guide (222) engages around the bolt (500) to form an axially and rotationally movable sliding bearing

AI summary
The invention relates to a housing, comprising: - a housing body (100), which has an upper opening and two mutually opposite side walls (110), the upper edges of which side walls laterally delimit the opening and the inner faces of which side walls each bear a cover guide groove (120), the cover guide groove being near the upper edge in question and extending longitudinally; and - a plate-type cover (200) having lateral, longitudinally extending guide edges (210), the cover being slidably mounted on the housing body (100) by means of the engagement of the cover in the cover guide grooves (120) of the housing body (100). The invention is characterized in that the housing body (100) bears, on the outer face of one of the side walls (110), a pin (500) oriented parallel to the cover guide grooves (120), and the cover (200) bears a sleeve (222), which is fastened to a tab (220) protruding over the corresponding side-wall upper edge of the housing body (100) and is oriented coaxial to the pin (500) and which engages around the pin (500) so as to form an axially and rotationally movable plain bearing.
