为了解决上述问题,设计出一种排放压力(开启压力)和回座压力(关闭压力)稳定性、重复性好,而且结构紧固,不易损坏、安全性能好的安全阀成为本领域的研究亮点。
实用新型内容
为克服上述同类技术存在的不足,本实用新型的目的是提供一种低温绝热气瓶安全阀。该安全阀特别适用于机动车用液化天然气焊接绝热气瓶、焊接绝热气瓶和低温管道热传导泄压应用,保证压力容器及压力管道的安全运行。
本实用新型的技术方案是:一种低温绝热气瓶安全阀,包括阀体,所述阀体包括设置在其内部的进气流道、阀座、滑道、阀芯和弹簧,所述阀体的进气端的外壁上设置有进气口连接螺纹,所述阀体的出气端安装有调节螺母,所述调节螺母上设置有调节螺母排气孔,所述弹簧安装在调节螺母与带有排气孔的弹簧支架间,所述弹簧支架下方的阀体内腔内安装有活门组合件,所述活门组合件由阀芯、安装在阀芯外壁上的导向环、定位钢珠和阀瓣组成,所述阀芯上设置有阀芯排气孔,带有排气孔的弹簧支架设置在定位钢珠上,所述阀瓣坐落在阀座上,阀瓣与阀座紧密配合。
作为优选技术方案,本实用新型的所述阀瓣为圆弧形阀瓣,所述圆弧形阀瓣与阀座紧密配合。
作为优选技术方案,本实用新型的所述导向环为聚四氟乙烯导向环,所述阀芯外壁上相间设置有两个聚四氟乙烯导向环。
作为优选技术方案,本实用新型的所述弹簧、弹簧支架、定位钢珠、阀芯、阀瓣的中心在同一中心线上。
本实用新型的有益效果是:
本实用新型用于低温机动车用液化天然气焊接绝热气瓶和焊接绝热气瓶,保证低温机动车用液化天然气焊接绝热气瓶和焊接绝热气瓶的安全运行,有效减少恶性事故发生的可能性。
本实用新型其排放压力(开启压力)和回座压力(关闭压力)的稳定性、重复性、密封性非常好,起到压力保护作用,提高机动车用液化天然气焊接绝热气瓶和焊接绝热气瓶的安全性,该安全阀结构紧固,不易损坏,安全性高。
为了确保安全阀动作可靠性和密封性,安全阀设有运动部件的导向机构,即该安全阀在其阀芯外表面增设了2只四氟乙烯导向环,这样可减少阀芯与滑道之间的摩擦力,也确保了热胀冷缩的温度因素。
为了确保安全阀动作的稳定性和重复性,安全阀设置运动部件中心定位机构,即该安全阀在其阀芯内设置了弹簧支架与定位钢珠,且弹簧、弹簧支架、定位钢珠、阀芯、阀瓣的中心在同一中心线上,这样起到阀瓣与阀座的中心定位作用,当阀瓣在阀座上方升启时能确保其面积不变。
本实用新型能解决现用安全阀存在的不足,为了确保安全阀动作可靠性和密封性,设置了运动部件的导向机构,为了确保安全阀动作的稳定性和重复性,设置了运动部件中心定位机构,起到了超压安全保护作用,从而避免重大事故发生,解决能源的浪费问题。导向机构的改进和中心定位机构的设计,使其结构合理,安全性能高。
附图说明
图1是本实用新型实施例1的结构示意图。
具体实施方式
下面结合具体实施例,进一步阐述本实用新型。应理解,这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围。此外应理解,在阅读了本实用新型讲授的内容之后,本领域技术人员可以对本实用新型作各种改动或修改,这些等价形式同样落于本申请所附权利要求书所限定的范围。
参照附图1,提出本实用新型的具体实施例1,如图1所示,一种低温绝热气瓶安全阀,包括阀体1,所述阀体1包括设置在其内部的进气流道3、阀座4、滑道6、阀芯7和弹簧13,所述阀体1的进气端的外壁上设置有进气口连接螺纹2,所述阀体1的出气端安装有调节螺母14,所述调节螺母14上设置有调节螺母排气孔16,所述弹簧13安装在调节螺母14与带有排气孔12的弹簧支架11间,所述弹簧支架11下方的阀体内腔内安装有活门组合件,所述活门组合件由阀芯7、安装在阀芯7外壁上的聚四氟乙烯导向环8、定位钢珠10和阀瓣5组成,所述阀芯7外壁上相间设置有两个聚四氟乙烯导向环8。所述阀芯7上设置有阀芯排气孔9,带有排气孔12的弹簧支架11设置在定位钢珠10上,所述阀瓣5坐落在阀座4上,阀瓣5与阀座4紧密配合。本实用新型的所述阀瓣5为圆弧形阀瓣,所述圆弧形阀瓣与阀座4紧密配合。
本实用新型的所述弹簧13、弹簧支架11、定位钢珠10、阀芯7、阀瓣5的中心在同一中心线上。
本实用新型使用中,天然气通过管道从进气流道3进入阀体1内部,当低温机动车用液化天然气焊接绝热气瓶内胆压力达到安全阀开启压力(排放压力)时,天然气压力推动阀瓣5向上移动离开阀座4,达到全启的开启高度,此时阀瓣5推动阀芯7,阀芯7在同一个中心位置上推动定位钢珠10、弹簧支架11,弹簧支架11压缩弹簧13,聚四氟乙烯导向环8可以减少阀芯7与滑道6之间的摩擦力,天然气通过进气流道3、阀芯排气孔9和弹簧支架11上的排气孔12进入阀体1,最后通过调节螺母排气孔16将天然气排出,降低低温机动车液化天然气焊接绝热气瓶内胆压力。当内胆压力降至安全阀关闭压力值时(回座压力),弹簧13推动在同一中心位置上的弹簧支架11、定位钢珠10和阀芯7,使阀瓣5恢复到阀座4上,使安全阀处于关闭的位置,密封住内胆的气体不再排出。
以上所述仅为本实用新型的优选实施例,并非因此而限制本实用新型的专利范围,凡是利用本实用新型说明书及附图内容所作的等效结构变换,或直接或间接运用在其他相关的技术领域,均同理包括在本实用新型的专利保护范围内。
