Description

一种导流卸压阀 技术领域
本发明涉及煤矿开采技术领域，尤其涉及一种导流卸压阀。
背景技术
向煤层尤其是高应力下的高瓦斯松软突出煤层打钻或抽采瓦斯过程中，极易造成钻孔、抽采管道内大量瓦斯聚集、超限，给煤矿的安全、高效生产造成威胁，目前，针对此类瓦斯浓度超限问题，通常运用卸压阀释放瓦斯管道内的瓦斯，降低瓦斯压力，但现有卸压阀均是短时彻底卸压，不可避免的造成大量瓦斯的突然运动，不能完全有效地消除安全隐患，极易对设备和人员造成危害。
发明内容
本发明提供了一种导流卸压阀，可及时降低瓦斯流通管道内的瓦斯压力，保证钻孔施工和瓦斯抽采的安全。
本发明提供了一种导流卸压阀，其包括：设于导流管道内的阀盖、与所述阀盖相配合的阀体、以及实现所述阀体与所述阀盖抵接或分离的抵接件，所述阀盖上设有卸压孔，所述阀体抵接于所述卸压孔处，所述抵接件在受到的作用力超过预设作用力阈值时实现所述阀盖与所述阀体的分离。
进一步地，所述抵接件包括固定于所述导流管道内与所述阀体间隔设置的支撑板、以及设于所述阀体与所述支撑板之间的弹性连接件。
进一步地，所述弹性连接件为弹簧。
进一步地，所述阀盖固定于所述导流管道内，所述卸压孔开设于所述阀盖的中间部位。
进一步地，所述阀盖与所述阀体之间的接触部位垫设有密封垫。
进一步地，所述密封垫为橡胶垫。
进一步地，所述阀盖的外部尺寸与所述导流管道内壁尺寸相适应，与所述阀体对应的所述阀盖的表面开设有锥形凹槽，所述阀体为与所述锥形凹槽尺寸相适应对应抵接于所述锥形凹槽内的锥体，所述卸压孔位于所述锥形凹槽的槽 底。
本发明实施例通过设置阀盖、阀体以及实现阀体与阀盖抵接或分离的抵接件，阀体抵接于卸压孔处，抵接件在受到的作用力超过预设作用力阈值时实现阀盖与阀体的分离，由阀盖与阀体之间的分离或抵接实现卸压阀的打开与关闭，从而实现压力超标时卸压阀的自动卸压，及时降低瓦斯流通管道内的瓦斯压力，保证钻孔施工和瓦斯抽采的安全。
附图说明
为了更清楚地说明本发明实施例技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的一种导流卸压阀的内部结构剖视图；
图2为本发明实施例提供的一种导流卸压阀的结构爆炸示意图；
图3为本发明实施例提供的一种导流卸压阀的I-I剖面图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应当理解，当在本说明书和所附权利要求书中使用时，术语“包括”和“包含”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
还应当理解，在此本发明说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本发明。如在本发明说明书和所附权利要求书中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
参见图1和图2，图1是本发明实施例一提供的一种导流卸压阀的内部结构剖视图，其包括设于导流管道1内的阀盖2、与阀盖2相配合的阀体3、以及实现阀体3与阀盖2抵接或分离的抵接件4，阀盖2上设有卸压孔21，阀体3抵接于卸压孔21处，抵接件4在受到的作用力超过预设作用力阈值时实现阀盖与阀体3的分离。
具体地，导流管道1的一侧为瓦斯进口11，另一侧为瓦斯出口12，瓦斯流入瓦斯进口1内，当瓦斯压力对阀体3与阀盖2之间的作用力小于预设作用力阈值时，抵接件4会促使阀体3与阀盖2相抵接，从而实现卸压阀的闭合。当瓦斯压力对阀体3与阀盖2之间的作用力不小于预设作用力阈值时，抵接件4则会促使阀体3与阀盖2分离，从而实现卸压阀的打开，对内部瓦斯压力进行卸压。
具体地，通过设置阀盖2、阀体3以及实现阀体3与阀盖2抵接或分离的抵接件4，阀体3抵接于卸压孔21处，抵接件4在受到的作用力超过预设作用力阈值时实现阀盖2与阀体3的分离，由阀盖2与阀体3之间的分离或抵接实现卸压阀的打开与关闭，从而实现压力超标时卸压阀的自动卸压，及时降低瓦斯流通管道内的瓦斯压力，保证钻孔施工和瓦斯抽采的安全。
参见图1，在一实施例中，抵接件4包括固定于导流管道1内与阀体3间隔设置的支撑板41、以及设于阀体3与支撑板41之间的弹性连接件42。
在一实施例中，弹性连接件42为弹簧。
具体地，可例如将抵接件4设置为物理性质的弹性抵接件，其由弹性连接件42和支撑板41组成，弹性连接件42可例如为弹簧。在具体实现中，可例如将支撑板41间隔固定在阀体3的瓦斯出口12侧，通过弹簧与阀体3相连，弹簧初始为压缩状态，通过弹簧自身的回复力将阀体3压在阀盖2上，当瓦斯在瓦斯进口11处的作用力大于弹簧的回复力时，则会继续压缩弹簧，从而使得阀体3与阀盖3分离，实现卸压阀的打开卸压，此时作用力阈值大小即为弹簧在初始状态下的回复力的大小，当瓦斯进口11处的作用力随着瓦斯排卸减小到小于弹簧回复力后，弹簧则会继续将阀体3压在阀盖2上，从而实现卸压阀的自动关闭。
在一实施例中，阀盖2固定于导流管道1内，卸压孔21开设于阀盖2的中间部位。
参见图1-图3，在一实施例中，阀盖2与阀体3之间的接触部位垫设有密封垫5。
在一实施例中，密封垫5为橡胶垫。
具体地，设置密封垫5一方面可以提高卸压阀自身的气密性，另一方面也可以起到阀体3与阀盖2之间的缓冲作用，提高卸压阀的使用寿命。
在一实施例中，阀盖2的外部尺寸与导流管道1内壁尺寸相适应，与阀体3对应的阀盖2的表面开设有锥形凹槽，阀体3为与锥形凹槽尺寸相适应对应抵接于锥形凹槽内的锥体，卸压孔2位于锥形凹槽的槽底。
在本申请所提供的实施例中，应该理解到，所揭露的内容，仅仅是示意性的，可以通过其它的方式实现。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
