OverviewThe JM742X Diaphragm Type Bottom Sludge Discharge Valve is a specialized valve designed for sludge discharge in sedimentation tanks, sewage tanks, and similar facilities. It operates by actuating the valve core through a diaphragm to achieve sludge discharge and cutoff at the tank bottom. The valve consists of components including the valve body, valve cover, diaphragm, valve core, valve stem, control chamber, and pneumatic/electrical control device.JM742X Diaphragm Type Bottom Sludge Discharge Valve Product DiagramFeature1. Diaphragm Sealing Structure: A high-strength elastic rubber diaphragm is used to completely isolate the valve body flow passage from the valve cover drive mechanism. The controlled medium only contacts the diaphragm and the inner cavity of the valve body, achieving a sealing solution that is packing-free and has zero external leakage. This design is particularly suitable for hazardous media or applications where contamination must be prevented.2. Streamlined Straight-Through Valve Body: The inner cavity of the valve body is smooth and unobstructed, forming an unimpeded flow path. This design minimizes resistance during medium flow and reduces the likelihood of turbulence, effectively preventing sludge or impurities from accumulating or becoming lodged within the valve, ensuring smooth discharge.3. Dedicated Design for Tank/Pool Bottom Installation: The valve features a compact structure with a low overall height, specifically optimized for flange installation at the bottom of tanks or pools. The opening and closing stroke of the valve disc or clapper is designed to address the discharge characteristics of settled sludge, effectively breaking up bridging phenomena and enabling complete sludge removal.4. Wear and Corrosion Resistance: The inner cavity of the valve body and the diaphragm in contact with the medium can be customized according to the medium's properties. Materials such as wear-resistant and corrosion-resistant rubber (e.g., NBR, EPDM) or linings can be selected, while key components may be made of stainless steel or copper alloy. This enhances the valve's service life in harsh operating conditions.5. Versatile Actuation Methods: The valve is typically equipped with hydraulic, pneumatic, or electric actuation devices (the "7" in the model number often represents hydraulic actuation). Operation is controlled by applying or releasing pressure in the air/liquid chamber above the diaphragm. The valve's open/closed status is visually clear, and its quick opening/closing action facilitates remote automatic control.

OverviewThe 100S angle type diaphragm sludge discharge valve is a specialized angular valve utilizing rubber membrane as its actuator and sealing element, designed for intermittent automatic sludge or wastewater discharge at the bottom of water treatment systems. Its core mechanism drives the membrane actuator via external pressure sources (typically clean water or compressed air), enabling rapid valve stem and disc operation. When pressurized, the membrane chamber keeps the disc closed; when depressurized, the disc opens under medium pressure or self-weight to discharge. This valve employs angular channels for 90-degree redirection between vertical inlet and horizontal outlet, featuring a compact structure that effectively prevents sludge accumulation and clogging. As a critical component in sedimentation tanks, clarifiers, and sand filters, it enables timed and quantitative automatic sludge discharge.100S Angle type Diaphragm Sludge Discharge Valve Product Diagram Feature1. The angular structure and anti-clogging design feature a 90-degree flow channel with vertical inlet connection to the pool bottom and horizontal outlet. This configuration abruptly alters the flow direction of the medium, effectively preventing solid particle deposition and clogging within the valve chamber. It ensures reliable operation and is particularly suitable for slurry media containing particles or fibers.2. Thin-film actuation ensures high sensitivity and reliability: The core drive and sealing element is a rubber membrane, driven by the pressure difference between water or gas. The membrane completely isolates the control medium from the working medium, eliminating dynamic seal leakage points. It features rapid response, high thrust, and low control pressure requirements (typically 0.15–0.6 MPa for operation).3. Dual Sealing and Maintenance Convenience: Valves typically feature a dual-sealing design, where the diaphragm serves as the primary seal while the valve disc and seat form the secondary seal, ensuring excellent sealing performance and airtight closure. When the diaphragm wears out, the valve can be replaced online by simply removing the valve cover without disassembling the pipeline, facilitating easy maintenance.4. Corrosion resistance and long service life: The main flow components (valve body, valve cover) can be made of cast iron, ductile iron, or stainless steel, and the inner cavity can be lined with rubber. The rubber film and valve disc sealing materials (such as nitrile rubber, EPDM rubber) are wear-resistant and resistant to mud and water corrosion, ensuring a long service life.5. Automatic control, energy-efficient and high-performance: It can be easily connected with solenoid valves, time relays, or PLCs to achieve fully automatic program control (timed and batch sludge discharge). The valve consumes only a small amount of water or gas during the instant opening/closing process, significantly saving water or electricity compared to normally open sludge discharge, thereby reducing operating costs.

Its structure is simple, free from complex electrical or hydraulic components, and has a low failure rate. It demonstrates significant advantages in scenarios requiring no power or high reliability.2. Hidden rod design for anti-fouling and durability: The valve employs a concealed rod lifting mechanism, with the valve stem threads located internally within the valve body, isolated from the medium, while only the handwheel rotates externally. This design effectively prevents sludge, fibers, and other impurities from entangling or corroding the exposed valve stem, thereby extending the valve's service life and ensuring a cleaner operating environment.3. Sealing options include hard or soft seals: The valve disc can be fitted with either a metal hard seal (wear-resistant and heat-resistant) or a rubber/polyurethane soft seal (highly airtight and wear-compensating), designed to meet stringent sealing requirements for different media such as clean water and slurry.4. Angular flow channel ensures smooth discharge: The angular valve body features a vertical downward inlet connected to the pool bottom and a horizontal outlet. The flow channel's turning design facilitates the smooth discharge of sediment, reduces dead zones for mud accumulation within the valve cavity, and ensures unobstructed discharge.5. Easy maintenance and cost-effective: The valve features an intuitive structure, requiring only routine inspections of the stuffing box and lubrication replenishment. For major overhauls, disassembly and replacement of internal seals are relatively straightforward. Its manufacturing and maintenance costs are significantly lower than those of automatic valves, making it highly economical and practical in non-frequent or non-automatic control applications.
