Abstract

一种煤气球阀,包含有阀体及球形旋塞,球形旋塞位于阀体内,且密封副位于阀体和球形旋塞之间,旋销一端联接旋塞,另一端装有手柄,其特点是在旋销和阀体之间安装有O形密封圈。本实用新型可以有效防止介质从旋销部位泄漏,从而保证了在煤气管道系统中使用时的安全性和可靠性。

Description

煤气球阀
一种煤气球阀,涉及通过塞子旋转运动而启闭的阀。
中国专利96229320.2号公告了一种《煤气报警安全阀》主要由阀体和报警器所组成。在阀体内设置有一球阀,在球阀上,设置有扭簧和档杆,在阀体内设置有电磁铁。它具有声光报警和自动关闭煤气的功能,而且还设置有手动和自动两种装置。但这种煤气报警安全阀不能解决阀体自身泄漏问题。
实用新型的目的是提供一种煤气球阀,它能有效解决阀自身泄漏的问题。
本实用新型采用这样的技术方案:该煤气球阀包含有阀体及球形旋塞,球形旋塞位于阀体内且密封付位于阀体和球形旋塞之间,旋销一端联接旋塞,另一端装有手柄,其特点是在旋塞和阀体之间安装有O形密封圈。
本实用新型在旋销和阀体的结合中,采用O形密封圈,从而有效地防止了介质从旋销部位的泄漏。从而保证了本煤气球阀在煤气管道系统中使用时的安全性和可靠性。
实用新型的具体结构由以下的实施例及其附图给出。
附图为依据本实用新型提出的煤气球阀结构示意图。
以下结合附图及实施例对依据本实用新型提出的煤气球阀作进一步的说明。
如附图所示,本煤气球阀包含有阀体(6),球形旋塞(4)安装在阀体内,并且通过旋塞的旋转实现阀的启闭。在阀体和球形旋塞之间装有密封付(5),对密封副采用预留压紧量来保证密封,旋销(3)一端联接在球形旋塞上,另一端伸出阀体与手柄(1)相连。因此,通过手柄的转动,就可操纵球形旋塞动作。在旋销和阀体之间安装有O形密封圈(2)。为更加有效地进行密封,以防介质从旋销部位泄漏,最好采用两道以上O形密封圈进行密封。本煤气球阀的零件除手柄和密封元件外,均采用黄铜材料,并在零件表面镀上镀层,例如镀镍或镀铬。由此可保证产品的内腔在与煤气中残存的有害元素长期接触时具有良好的耐蚀性能。

Claims (3)

1、一种煤气球阀,包含有阀体及球形旋塞,球形旋塞位于阀体内,且阀体和球形旋塞之间装有密封付,旋销一端联接旋塞,另一端装有手柄,其特征是旋销和阀体之间安装有O形密封圈。
2、如权利要求1所述球阀,其特征是在旋销和阀体之间至少安装有两道O形密封圈。
3、如权利要求1或2所述煤气球阀,其特征是阀体、旋塞及旋销表面有镀层。
