内容详情

JCH-TIKTOP is specialized in the R&D, production and sales of mining fluid control valves. Aiming at the complex working conditions of mining slurry, tailings mud, solid-containing particle slurry and other materials, the company specializes in producing the **pneumatic pinch valve (also known as rubber hose valve and air bag valve)** series products. Driven by pneumatic actuators, the valves open and close and adjust the flow rate by squeezing the wear-resistant rubber sleeve. They are non-clogging, non-scaling and reliable in sealing, which perfectly solves the problems of easy jamming, wear and leakage of traditional valves in slurry pipelines. The products are widely used in mineral processing, tailings dry discharge, mud transportation, environmental protection sewage treatment and other scenarios.

I. Product Introduction of Pneumatic Pinch Valves

The pneumatic pinch valve is composed of a valve body, a wear-resistant rubber sleeve, a pneumatic actuator, a bracket and other parts. It uses compressed air to push the actuator to squeeze the rubber sleeve, causing the rubber sleeve to deform and close or reset and open, thereby realizing the on-off control of the pipeline. The inner surface of the rubber sleeve is smooth and straight without any flow-blocking structures. It is particularly suitable for conveying pipelines containing solid particles, fibers and viscous media such as ore pulp, mud and tailings pulp, and is an ideal control valve for wet mining processes.

II. Main Product Types

  1. Classified by connection method

    • Flanged pneumatic pinch valve: firm connection and stable pressure resistance, suitable for mine main pipelines and large-diameter pipelines

    • Wafer-type pneumatic pinch valve: compact structure and easy installation, suitable for branch pipelines with narrow space

  2. Classified by the material of the rubber sleeve

    • Wear-resistant natural rubber sleeve: Suitable for ordinary mineral slurry and tailings mud, with excellent erosion resistance and elasticity

    • Acid-alkali resistant synthetic rubber sleeve: Suitable for acidic and alkaline leached mineral pulp, with corrosion resistance and long service life

    • Reinforced wear-resistant rubber sleeve: Designed for high-concentration coarse particle slurries, with superior tear resistance and wear resistance.

III. Core Components

  • Rubber sleeve: The core vulnerable part of the pinch valve, integrally molded with special wear-resistant/corrosion-resistant rubber, easy to replace

  • Pneumatic actuator: Driven by an air cylinder, it features stable operation, quick opening and closing, and is compatible with remote automatic control systems.

  • Valve body: Made of cast steel, with high structural strength, which protects the rubber sleeve and provides extrusion support.

  • End covers, fasteners and brackets: standardized parts with firm installation and strong versatility

  • Pneumatic control accessories: solenoid valves, limit switches, air source triplets, etc., which can realize automatic control and status feedback

IV. Product Performance Features

  1. Straight-through flow channel without clogging

    No gate plate or valve core inside, and the smooth rubber sleeve flow channel does not stick materials or jam particles, completely solving the problem of slurry blocking the valve

  2. Excellent sealing performance

    It seals by the deformation of the rubber sleeve, with no risk of leakage, and can achieve reliable sealing even if the medium contains impurities.

  3. Strong wear and corrosion resistance

    The special rubber sleeve resists scouring by ore slurry particles and acid-base corrosion, with a service life far superior to that of metal-sealed valves.

  4. Stable and efficient pneumatic drive

    The cylinder actuator opens and closes quickly, supports remote automatic control, is suitable for mine automation pipeline systems, and is labor-saving to operate.

  5. Easy maintenance and low cost

    It can be put back into use only by replacing the rubber sleeve without disassembling the valve body, which greatly reduces maintenance time and operation and maintenance costs.

  6. Widely applicable to working conditions

    It can work stably for a long time in slurry media with high concentration, high viscosity, containing particles and corrosive.

V. Scope of Application

  • Applicable industries: Metal mine beneficiation, tailings transportation, coal washing and selection, metallurgical chemical industry, environmental protection sludge treatment, sand and gravel slurry transportation

  • Applicable media: ore pulp, tailings slurry, acidic/alkaline ore pulp, mud, coal slime, fibrous slurry, solid-containing granular sewage

  • Applicable working conditions: On-off control of slurry pipelines, tailings dry-discharge systems, feed pipelines of filter presses, and corrosive medium pipelines

VI. Standard Product Specifications (Custom Non-standard Sizes Available)

  • Diameter specification: DN25～DN600

  • Connection method: Flange type, Wafer type

  • Drive mode: Pneumatic (single-acting / double-acting cylinder)

  • Valve body material: Cast steel

  • Bushing material: Wear-resistant rubber, acid and alkali resistant rubber, enhanced wear-resistant rubber

  • Working pressure: Conventional low-pressure / medium-pressure pipelines, and the pressure-bearing specifications can be customized according to working conditions

VII. Core Advantages of Hainan Sikejia Mining Equipment
