Telescopic Soft Seal Gate ValveIt Is A Pipeline Control Valve That Integrates Expansion Compensation And Soft Seal Cutoff. Its Core Function Is To Cut Off Or Connect The Medium, While Compensating For Pipeline Thermal Expansion And Contraction, Installation Errors, And Axial Displacement Through The Expansion Structure To Prevent Stress Damage To The Pipeline And Ensure Long-term Stable Operation Of The System. Widely Used In Pipeline Systems Such As Water Supply And Drainage, Municipal, HVAC, Industrial, Etc., It Is A Key Accessory That Balances Sealing And Safety, With A Total Word Count Controlled Within 500 Words.

Structurally, It Mainly Consists Of A Valve Body, A Gate Plate (with Overall Rubber Coating), An Expansion Joint, A Valve Stem, And A Driving Mechanism. The Valve Body Is Mostly Made Of QT450-10 Ductile Iron Or Stainless Steel, Which Has High Strength And Corrosion Resistance; The Gate Is Entirely Covered With NBR/EPDM Rubber, With A Sealing Layer Thickness Of 6-9mm And Strong Elastic Deformation Compensation Ability; The Expansion Joint Is Integrated Into The Valve Body And Can Be Adjusted In Length On Site, Suitable For DN50-DN1200 Caliber. The Connection Method Is Mainly Flange Based And Complies With Standards Such As GB/T 17241.6. The Driving Methods Include Manual, Electric, And Pneumatic, With A Compact Concealed Structure Suitable For Underground And Space Limited Scenarios.

Significant Core Features: ① Reliable Sealing, Adaptive Fit Between Elastic Gate And Valve Seat, Low Leakage, Suitable For 0-80 ℃ Media, Meeting Standards Such As CJ/T 216 And GB/T 13927; ② Expansion Compensation Can Compensate For ± 50-200mm Axial Displacement, Reduce Pipeline Stress, And Lower Installation Costs; ③ Efficient Installation, No Need For Precise Calculation Of Pipe Length, On-site Fine-tuning For Assembly, Supports Online Maintenance Of Seals; ④ Smooth Flow, No Stagnant Area In The Straight Channel, Low Resistance Loss, Suitable For High Flow Conditions.

The Application Scenarios Cover Municipal Water Supply And Drainage Main Pipes, Residential Water Supply, HVAC Circulating Water, Industrial Circulating Water, And Fire Protection Pipeline Networks, Especially Suitable For Long-distance Transportation, Underground Installation, Or Pipeline Systems With Large Temperature Differences. Compared To Ordinary Soft Sealed Gate Valves, Its Telescopic Function Solves The Pain Points Of Pipeline Deformation, And The Installation And Maintenance Costs Are Lower. It Is The Preferred Cut-off And Compensation Device For Water Supply And Drainage And Industrial Pipelines.
