HRKH高压球阀产品概述

HRKH高压球阀是一种适用于高压工况的阀门产品，通常具有良好的耐压性与密封性，以下是其产品概述：

HRKH高压球阀- 结构组成：一般采用锻造工艺制造，阀体材质常为S355J2G3、不锈钢（1.4571/316Ti）等，球体和阀杆也多由不锈钢制成，密封材料为塑料，具有较好的耐磨性和耐腐蚀性 。

HRKH高压球阀- 工作原理：通过阀杆带动球体旋转来实现阀门的开闭。当球体旋转90度时，可实现全开或全关，从而控制介质的通断。开启时球体通孔与阀体通道对齐，介质顺利通过；关闭时球体阻挡介质流动，依靠球体与阀座的密封面实现密封 。

HRKH高压球阀- 特点优势：耐压能力强，设计压力通常≥10MPa，部分型号可承受超高压。密封稳定，小口径常采用金属硬密封，可耐受高压下的介质冲刷和挤压；阀杆密封采用多级填料结构，防止介质泄漏。操作设计适配高压工况，通常配备增力传动装置，或直接采用气动/电动执行器，确保启闭顺畅 。

HRKH高压球阀- 技术参数：公称压力可达PN700bar~PN800bar，公称通径为DN13~DN25，适用温度范围根据密封材料和阀体材质不同而有所差异，一般可在-20℃至80℃左右，部分特殊材质可耐受更高温度 。

HRKH高压球阀- 应用领域：广泛应用于液压系统、气体行业、环境工业、石油化工行业等，可用于控制油、液压油、酸性气体、水蒸气、乳化液等多种介质的流通 。

 HRKH high - pressure ball valve is a kind of valve product suitable for high - pressure working conditions, usually with good pressure - resistance sealing performance. The product overview is as follows:

 HRKH high - pressure ball- Structural composition: It is generally manufactured by forging process. The valve body materials are often S355J2G3, stainless steel (1.4571/316Ti), etc. The ball valve stem are also mostly made of stainless steel, the sealing material is plastic, which has good wear - resistance corrosion - resistance.

HRKH high - pressure ball- Working principle: The opening closing of the valve are realized by the valve stem driving the ball to rotate. When the ball rotates 90 degrees, full - open full - close can be achieved, so as to control the on - off of the medium. When opening, the through - hole of the ball is aligned with the valve body channel, the medium passes smoothly. When closing, the ball blocks the medium flow, the sealing is realized by relying on the sealing surface of the ball the valve seat.

HRKH high - pressure ball- Features advantages: It has strong pressure - resistance, the design pressure is usually ≥ 10MPa, some models can withstand ultra - high pressure. The sealing is reliable. Metal hard - seal is often used for small - diameter valves, which can withstand the scouring extrusion of the medium under high pressure. The valve stem sealing adopts a multi - stage packing structure to prevent the medium leaking. The operation design is suitable for high - pressure working conditions. It is usually equipped with a force - increasing transmission device, a pneumatic/electric actuator is directly used to ensure smooth opening closing.

HRKH high - pressure ball- Technical parameters: The nominal pressure can reach PN700bar~PN800bar, the nominal diameter is DN13~DN25. The applicable temperature range varies according to different sealing materials valve body materials, generally about - 20℃ to 80℃, some special materials can withstand higher temperatures.

HRKH high - pressure ball- Application fields: It is widely used in hydraulic systems, gas industry, environmental industry, petrochemical industry, etc., can be used to control the flow of various media such as oil, hydraulic oil, acidic gas, water vapor, emulsion, etc.
