Description
技术领域
本发明涉及阀门领域，具体是一种杆芯一体式带过滤网焊接球阀。
背景技术
球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业，在国民经济中占有举足轻重的地位。球阀中设有球体，主要通过旋转球体来实现开启或者关闭介质通路的功能，再能起到切断、分配和改变介质流动方向的作用。
在现有技术中，球阀的阀杆与球芯分离，用阀杆插入球阀芯的槽口来实现同步旋转控制，但同时球阀芯的槽口语阀杆磨损严重，容易松动，失去同步控制效果，球阀使用寿命短。而含有杂质的介质进入球阀密封面，会加快阀芯的磨损速度，球阀的使用寿命短。
发明内容 本发明旨在提供一种杆芯一体式带过滤网焊接球阀，旨在解决上述问题。
为实现上述目的，本发明的技术方案如下：
一种杆芯一体式带过滤网焊接球阀，包括左阀体、右阀体，其特征在于：左阀体与右阀体通过焊接形成一个整体式阀体，阀体中间设有与阀杆一体铸造成的阀芯；所述的阀杆与阀体连接处设有止渗部件；所述左阀体与右阀体在靠近端口位置上还开有环槽，环槽连通到阀体外表面，环槽内设置有与介质流体通道适配的过滤网，过滤网设有金属固定边框，金属固定边框包裹在氟橡胶圈内；所述氟橡胶圈的直径大于介质流体通道的直径。
进一步地，所述做阀体与右阀体外表面开有与环槽适配的孔格，并设置有与孔格适配的保护盖。
进一步地，所述金属固定边框设置有拉钩。
进一步地，所述阀杆与阀体之间设置有密封O形圈。
进一步地，所述阀杆上还用螺栓连接有手轮。
一、本发明的有益效果在于：在介质流体通道内设置有过滤网，过滤网能够在恶劣工况中将大量残渣阻拦，避免进入球芯磨损过快。
二、同时在金属固定边框外包裹氟橡胶，能起到密封作用，避免介质从金属固定边框与阀体缝隙中泄露。
三、环槽连通到阀体外表面，在一段时间后，只需打开保护盖，拉起金属固定边框上的拉钩，就能将过滤网拉出清洗，清洗完后再将过滤网插入环槽内，结构简单，花费的时间少，经济实用。
四、阀杆与球芯一体式设计，杜绝了阀杆插头与球阀芯槽口的磨损，提高球阀的使用寿命。
五、阀体由左、右阀体焊接成，结构更稳定。
附图说明
图1是本发明提供的杆芯一体式带过滤网焊接球阀结构示意图。
图2是本发明提供的过滤网结构示意图。
图中标记：1为环槽、2为保护盖、3为右阀体、4为过滤网、5为阀座、6为阀芯。7为左阀体、8为阀杆、9为密封O形圈、10为手轮、11为止渗部件、12为拉钩、13为氟橡胶圈、14为金属固定边框。
具体实施方式
下面结合附图与具体实施例对本发明做进一步说明。
如图1、图2所示，一种杆芯一体式带过滤网焊接球阀，包括左阀体7、右阀体3，其特征在于：左阀体7与右阀体3通过焊接形成一个整体式阀体，阀体中间设有与阀杆8一体铸造成的阀芯6；所述的阀杆8与阀体连接处设有止渗部件11；所述左阀体7与右阀体3在靠近端口位置上还开有环槽1，环槽1连通到阀体外表面，环槽1内设置有与介质流体通道适配的过滤网4，过滤网4设有金属固定边框14，金属固定边框14包裹在氟橡胶圈13内；所述氟橡胶圈13的直径大于介质流体通道的直径。所述左阀体7与右阀体3的外表面开有与环槽适配的孔格，并设置有与孔格适配的保护盖2。所述金属固定边框14设置有拉钩12。所述阀杆与阀体之间设置有密封O形圈9。所述阀杆上还用螺栓连接有手轮10。
阀体由左、右阀体焊接成，结构更稳定。阀杆8与球芯6一体式设计，杜绝了阀杆插头与球阀芯槽口的磨损，提高球阀的使用寿命。同时在左阀体7与右阀体3的靠近端口位置设有方便取插的过滤网4，能够吸附大量的残渣，在金属固定边框外还抱过有氟橡胶圈，起到密封作用，防止介质从环槽的缝隙泄露。每经过一段时间，打开用于防尘的保护盖2，用钩子勾住拉钩即可从环槽内取出过滤网4进行清洗，简单快捷，效率高。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
