1. Core Application Orientation & Segmented User Demand

1.1 Core Usage & Matched Equipment Model

This batch of standardized hydraulic control valves, filtering elements, sealing fasteners, detection components and brake actuating parts is customized for 2000HP-3500HP onshore desert drilling rigs, offshore platform drawworks auxiliary brake units and skid-mounted hydraulic emergency caliper systems, fully compliant with GB1235, TB/T982, TB/ZQ4444, JB/T1978 national fluid component standards and API 7K drilling mechanical accessory certification. Production workshops hold ISO 9001 quality system qualification and SGS hydraulic pressure fatigue certification, providing traceable aftermarket spare parts for heavy-load fluid loop operation. Target segmented users cover drilling rig fleet maintenance teams, offshore EPC mechanical procurement departments, hydraulic brake system refurbishment factories and third-party oilfield component stocking vendors. Core user demands focus on OEM dimensional interchangeability, stable pressure regulation performance, anti-corrosion outdoor adaptability, unified standard interface, and one-stop part sourcing to eliminate mismatched assembly failure during on-site brake overhaul.

1.2 Pre-positioned Field Pain Points Solved By This Component Set

• Generic aftermarket globe valves generate spool jamming under 23MPa sustained hydraulic load, causing emergency caliper cylinder fail to cut off oil supply

• Non-standard O-rings and compound rings suffer compression deformation, triggering hydraulic oil leakage at valve block joints after 510 continuous operating hours

• Mismatched cotter pins, retaining rings and brake springs cause emergency caliper reset lag, leading to drilling drawworks running resistance rise

• Ordinary filter elements fail to intercept drilling impurity sludge, resulting in overflow valve and reducing valve internal valve core abrasion in sandy oilfield sites

2. Complete Product Technical Specification Introduction

2.1 Product Portfolio Overview

This full component lineup covers core fluid control parts and matched structural accessories: multi-spec globe valves (62210231,62220233,62211232), 61620201 shock-resistant pressure gauge, pressure regulating valves, return filter assemblies, customized valve blocks, emergency caliper cylinder unit, accumulator accessories, standard quick couplings, national-standard sealing rings, mechanical pin fasteners and electric control supporting parts. Exclusive field verified test data: this standardized component set extends emergency brake system overhaul cycle by 1210 working hours, and cuts on-site hydraulic loop debugging time by 8 working hours per routine maintenance compared with universal aftermarket parts.

2.2 Core Functional Description

All components collaborate to realize full-loop control of drilling emergency caliper brake system. Multi-model globe valves execute manual hydraulic circuit cut-off; reducing valve and overflow valve maintain loop constant working pressure; relay valve and hydraulic valve realize pneumatic-hydraulic linkage interlock; graded filter elements intercept metal scraps and mud impurities; 61620201 pressure gauge feeds real-time loop pressure data; accumulator and bladder store emergency standby hydraulic power; standard pins, springs and retaining rings guarantee mechanical reset and limit of 20302000 emergency caliper cylinder; standard seals and fittings eliminate joint fluid leakage under cyclic load.

2.3 Optimized Structural Characteristics

All valve bodies adopt precision honed integral casting structure with anti-scuffing inner coating; TB/T982 Compound Ring 24 adopts metal-rubber vulcanized integrated structure for dynamic sealing; head-type clevis pins add galvanized anti-rust surface treatment; M18×1.5 hexagon plug equips anti-backlash thread tooth; 61620201 pressure gauge builds built-in buffer damping structure for fluctuating hydraulic pressure. Practical field design: unified mounting thread size for same-series control valves, laser engraved part code for fast inventory classification, detachable filter cartridge structure for on-site replacement without pipeline disassembly.

2.4 Applicable Working Conditions

Adapt ambient working temperature from -35℃ to 62℃; fit desert high-sand, coastal salt-fog, offshore high-humidity harsh oilfield environments; stable operation under 0.7MPa rated pneumatic input pressure and 24MPa peak hydraulic loop pressure; compatible with ISO VG46 anti-wear hydraulic oil and water-glycol brake medium; suitable for outdoor exposed pipeline installation and Zone 2 non-explosive hydraulic cabin working scenarios.

2.5 Engineer Standardized Maintenance Rules & On-site Avoidance Tips

Replace all dynamic compound sealing rings every 820 continuous running hours; clean return filter and air filter elements every 360 operating hours; calibrate 61620201 pressure gauge numerical accuracy before seasonal rig startup; key avoidance tip: do not polish cylinder pin mounting holes when installing 20300106 clevis pin with head, which will enlarge assembly gap and cause caliper brake offset clamping under heavy hoisting load.
