Slide Valve TRIZ Cases

A sliding blind, actuator, and biasing ring create tight positive shut-off in a compact isolation valve while reducing worker exposure and space use.

Spring-loaded pinned clamp assemblies let the yoke translate axially while limiting gate tilt, improving knife gate valve sealing and stress distribution.

A removable valve insert with recessed seals and a retainer ring cuts oilfield valve repair time by avoiding weld repair and full disassembly.

An angled slider and threaded spindle let operators fine-tune fat flow onto dough sheets with better precision, easier use, and simpler cleaning.

Angled valve cover and cap sealing surfaces reduce bolt count, valve size, and weight while preserving reliable gate valve sealing.

A linearly movable recess regulates highly viscous liquids and melts while preventing dead space, stagnation, and flow accumulation.

Recessed gate surfaces shield subsea valve sealing areas from dropped tool-string impacts while preserving seal integrity and reducing maintenance.

Removable face seals and a T-shaped perimeter seal enable bidirectional zero-leakage knife gate valve sealing without debris pockets.

Continuous position sensing tracks vacuum valve wear and faults, helping prevent leaks while reducing unnecessary maintenance and downtime.

An integrated elastic member opens and seals gate plates smoothly while simplifying valve structure and allowing adjustable sealing strength.

A flexibly coupled valve disc and wedge seal maintain tight shutoff and gas flow control while reducing sticking, wear, and premature failure.

Retainers lock the seat and plate against axial and rotational movement, preserving bi-directional sealing and blocking debris buildup.

A monoplanar iris diaphragm uses adjustable concentric blades to cut turbulence, pressure drop, and fluid harmonic distortion.

An extended sleeve recess lets the clamp ring sit near the opening, reducing bending damage while preserving pipe grip and sealing.

A side-entry layout lets valve parts be replaced through the flow opening, cutting repair time, downtime, and labor in high-pressure service.

A valve bore assembly uses seats, bore bodies, seals, and pressurized grease to hold gate alignment, prevent leakage, and block particle bypass.

Structure-borne sound sensing inside the valve predicts seal wear and component issues, reducing unplanned maintenance downtime.

Moving upper and lower seals keep valve cavity volume constant, limiting particulate ingress, easing pressure equalization, and reducing leaks.

A round-rectangular cavity with U-shaped seals and a skirt assembly reduces valve weight while blocking debris and maintaining bidirectional sealing.

Angled sealing surfaces and a flexible wedge cut valve size and weight while improving sealing and simplifying cover assembly with fewer bolts.

Axially movable stem lugs switch a valve between balanced and unbalanced modes, cutting operating force and actuator size in high-pressure service.

A streamlined curved gate surface cuts mid-stroke turbulence, allowing higher flow with shorter valve stroke and better sealing.

A recessed disc surface and flow channels cut contact area and opening torque while preserving peripheral sealing in high-pressure multiple orifice valves.

Acceleration sensing inside the vacuum valve predicts seal wear, reducing unnecessary maintenance stops while preserving gas-tight process integrity.

Spring-loaded clamp assemblies preload the knife gate valve body while allowing axial gate translation to reduce tilting, stress, and leakage.

Multiple metering segments enlarge choke flow area for better pressure regulation, debris clearance, and lower pressure drop in drilling.

Solid low-friction coatings on hardened gate and seat faces cut torque, resist galling, and keep gate valves operating at high temperature.

A concave slot, convex ridge, and angled cover improve gate valve sealing while cutting weight, bolt count, and tolerance demands.

Retainer rings transfer gate loads to the valve body while wear rings and seals prevent contact, reducing dead-end service wear and replacement cost.

A hollow piston with side openings and multiple sealing rings cuts shutoff force, avoids dirt trapping, and smooths valve stroke.

Built-in temperature sensing tracks thermal effects on vacuum valve sealing, enabling condition-based maintenance and steadier gas-tight closure.

Locking members hold the sealing members until full closure, preventing premature engagement while balancing loads for a reliable seal.

Threaded seat inserts, annular seals, and springs block leakage paths and debris ingress while maintaining high-pressure gate valve sealing.

A tapered nut and large-bore valve plug fit multiple stem diameters, cutting part variants, simplifying assembly, and preventing leakage.
