  • Temperature measuring devices typically consist of a temperature sensing probe and a detection sleeve. During use, the end of the temperature sensing probe needs to be inserted into the detection sleeve. When inserting or removing the probe, the connection between the detection sleeve and the pipeline needs to be opened or closed promptly. When this connection is closed, the probe is difficult to insert or remove from the detection sleeve due to the sealing properties of the connection point between the detection sleeve and the probe end. Therefore, a temperature measuring device for high-temperature steam pipelines is proposed.

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合说明书附图对本发明的具体实施方式做详细的说明。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是本发明还可以采用其他不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下 做类似推广，因此本发明不受下面公开的具体实施例的限制。
其次，此处所称的“一个实施例”或“实施例”是指可包含于本发明至少一个实现方式中的特定特征、结构或特性。在本说明书中不同地方出现的“在一个实施例中”并非均指同一个实施例，也不是单独的或选择性的与其他实施例互相排斥的实施例。
实施例1，参照图1至图3，为本发明第一个实施例，该实施例提供了一种高温蒸汽管道温度测点装置，包括，输送机构100，其包括蒸汽管道101，以及固定设于蒸汽管道101上的套管102；在本实施例中，套管102焊接于蒸汽管道101的外壁表面，套管102和蒸汽管道101呈连通状态。
截止机构200，其包括固定设于套管102顶端的阀体201，以及固定设于阀体201内的封堵件202；在本实施例中，封堵件202能够控制阀体201内部通道的开启和关闭。
插套300，其固定设于阀体201的顶端；温度传感探头400，其滑动设于插套300的内壁；在本实施例中，温度传感探头400能够对温度进行检测，温度传感探头400的端部插入插套300后能够通过插套300进行密封。
需要说明的是，阀体201包括固定设于套管102顶端的壳体201a，以及设于壳体201a内的横向通道201b和纵向通道201c，还包括和横向通道201b以及纵向通道201c相连通的连通缺口201d，壳体201a上设有泄气孔201e；在本实施例中，壳体201a的两端均设有法兰结构，能够和套管102以及插套300进行连接，横向通道201b和纵向通道201c呈垂直设置且相互连通，连通缺口201d设于靠近插套300所在的部位，且连通缺口201d设于靠近泄气孔201e所在的一侧，泄气孔201e和横向通道201b相互连通。
需要说明的是，封堵件202包括固定设于壳体201a内的螺纹套202a，以及螺纹连接于螺纹套202a内壁的螺纹杆202b，还包括固定设于螺纹杆202b端部的转盘202c，螺纹杆202b的一端固定安装有封堵塞202d，在本实施例中，封堵塞202d滑动设于横向通道201b的内部，封堵塞202d位于横向通道201b和纵向通道201c所连通的部位时，能够将纵向通道201c进行截断；封堵塞202d靠近螺纹杆202b的一端经过倒角处理，连通缺口201d呈三角形结构，当封堵塞202d位于横向通道201b和纵向通道201c所连通的部位时，横向通道201b、纵向通道201c通过连通缺口201d进行连通，封堵塞202d沿着泄气孔201e所在方向运动时，滑入横向通道201b后，封堵塞202d将连通缺口201d进行覆盖，完成对横向通道201b靠近泄气孔201e一端的封堵。
在将温度传感探头400插入插套300内时，插套300内的气体能够通过温度传感探头 400的端部挤压进入连通缺口201d，经过横向通道201b后从泄气孔201e排出，方便温度传感探头400的插入，当温度传感探头400的端部接触到封堵塞202d之后，通过转动转盘202c，使得螺纹杆202b转动，进而使得封堵塞202d滑动，使得纵向通道201c的通道打开，由于封堵塞202d的滑动将和连通缺口201d错位，因此可以保障蒸汽不会经过连通缺口201d从泄气孔201e内泄漏，避免产生安全隐患，通过下压温度传感探头400使其前端插入套管102内，直至进入蒸汽管道101的内部，对高温蒸汽管道内部的温度进行测量，此时可以通过转动螺纹杆202b使得封堵塞202d的端部抵触温度传感探头400的插入部位，对温度传感探头400进行固定。
在测量完毕需要取下温度传感探头400时，先将温度传感探头400上提到合适的位置，再通过封堵塞202d将纵向通道201c进行封堵截断，避免蒸汽外泄的情况出现，随后向外抽出温度传感探头400，抽出时，外部的气体能够通过泄气孔201e进入横向通道201b，并通过连通缺口201d进入纵向通道201c内，方便温度传感探头400从套管102的内部抽出。
实施例2，参照图1～图7，为本发明第二个实施例，与上个实施例不同的是，还包括固定设于温度传感探头400外壁的定位机构500，以及固定设于壳体201a外壁的卡接机构600；定位机构500包括设于温度传感探头400外壁的连接件501，以及滑移设于连接件501内的锁定件502；卡接机构600包括固定设于壳体201a外壁的支撑件601，以及固定设于支撑件601上的一号卡接件602和二号卡接件603；截止机构200还包括滑移设于壳体201a外壁的限位件203。
具体的，连接件501包括连接架501a，以及设于连接架501a上的导向槽501b，还包括设于连接架501a上的扣帽501c，扣帽501c和连接架501a之间连接有固定螺栓501d，在本实施例中，通过固定螺栓501d能够将扣帽501c和连接架501a进行连接，方便将连接架501a和温度传感探头400之间进行安装和拆卸。
进一步的，锁定件502包括滑移设于连接架501a内的卡接框502a，以及滑动设于卡接框502a内的滑动框502b，滑动框502b的端部固定安装有卡接块502c，还包括设于滑动框502b内的弹簧502d；在本实施例中，滑动框502b能够在卡接框502a的内部滑动，弹簧502d的两端分别和滑动框502b以及卡接框502a相连接，卡接框502a远离卡接块502c的一端为斜面，卡接块502c远离卡接框502a的一端为斜面，且两者相互远离的一端表面呈相互平行的状态。
进一步的，卡接框502a的外壁固定安装有一号推柱502a-1；卡接块502c的外壁固定 安装有二号推柱502c-1，在本实施例中，一号推柱502a-1和二号推柱502c-1的外壁均与导向槽501b的内壁滑动连接。
优选的，限位件203包括旋转设于螺纹杆202b外壁的旋转套203a，以及固定设于旋转套203a外壁的限位套203b，还包括固定设于限位套203b顶端的一号限位杆203c和二号限位杆203d，在本实施例中，限位套203b能够在壳体201a的外壁水平滑移，在转动螺纹杆202b时，限位套203b将随着螺纹杆202b的位移一同进行水平滑移，一号限位杆203c靠近一号推柱502a-1设置，二号限位杆203d靠近二号推柱502c-1设置，一号推柱502a-1和二号推柱502c-1设于一号限位杆203c和二号限位杆203d之间。
较佳的，一号卡接件602包括固定设于支撑件601上的一号固定架602a，以及固定设于一号固定架602a顶部的一号卡接齿条602b；需要说明的是，二号卡接件603包括固定设于支撑件601上的二号固定架603a，以及固定设于二号固定架603a顶部的二号卡接齿条603b；一号卡接齿条602b上的齿槽和二号卡接齿条603b上的齿槽的朝向相反，在本实施例中，一号卡接齿条602b和二号卡接齿条603b的外壁均和连接架501a的内壁滑动连接，能够对连接架501a进行限位，增加连接架501a的稳定性，进而增加对温度传感探头400的固定效果。
优选的，卡接框502a的顶部固定安装有一号挤压块502a-3；卡接块502c的顶部固定安装有二号挤压块502c-3，通过一号挤压块502a-3和二号挤压块502c-3的设置方便使用者挤压卡接框502a和卡接块502c，便于对弹簧502d进行压缩。
其余结构均与实施例1相同。
在使用时，当封堵塞202d处于截断纵向通道201c的状态时，此时的二号限位杆203d和二号推柱502c-1处于抵触状态，锁定件502位于靠近一号卡接件602所在的区域，在弹簧502d的弹力作用下，卡接框502a能够卡接于一号卡接齿条602b的齿槽上，当封堵塞202d处于封堵状态时，能够限制温度传感探头400插入套管102的内部，使得温度传感探头400只能拔出，无法插入，可以避免温度传感探头400受力后其端部抵触封堵塞202d造成检测部位损坏，在需要控制温度传感探头400插入插套300内时，需要先挤压卡接框502a和卡接块502c，使得弹簧502d进行压缩，致使卡接框502a脱离和一号卡接齿条602b的卡接，此时才能控制温度传感探头400的插入。
当封堵塞202d运动至靠近泄气孔201e所在的部位时，由于一号限位杆203c推动一号推柱502a-1，一号推柱502a-1和二号推柱502c-1在导向槽501b的内壁滑动，使得锁定件502运动至靠近二号卡接件603所在的位置，此时一号限位杆203c和一号推柱502a-1处于抵 触状态，卡接块502c和二号卡接齿条603b上的齿槽处于卡接状态，此时温度传感探头400只能向插套300内插入，无法拔出，可以避免蒸汽管道101的内的压力将温度传感探头400顶出，若需要拔出温度传感探头400，则需要先挤压卡接框502a和卡接块502c，使得弹簧502d进行压缩，致使卡接块502c脱离和二号卡接齿条603b的卡接，此时才能控制温度传感探头400的拔出。
实施例3，参照图1～图8，为本发明第三个实施例，与上个实施例不同的是，支撑件601包括固定设于壳体201a外壁的支撑座601a，以及固定设于支撑座601a上的支撑板601b，支撑板601b上设有槽口601c，还包括由下至上均匀设置于槽口601c上的限位条601d，在本实施例中，支撑板601b设置有两个，且在支撑座601a上呈对称设置，支撑板601b的设置能够对一号限位杆203c和二号限位杆203d进行限位，增加一号限位杆203c和二号限位杆203d的强度。
具体的，一号推柱502a-1的端部固定安装有一号直角梯形块502a-2；二号推柱502c-1的端部固定安装有二号直角梯形块502c-2。一号直角梯形块502a-2靠近二号直角梯形块502c-2的一面为倾斜面，二号直角梯形块502c-2靠近一号直角梯形块502a-2的一面为倾斜面，且一号直角梯形块502a-2和二号直角梯形块502c-2相互靠近的一面呈平行状态。
其余结构均与实施例2相同。
当封堵塞202d处于截断纵向通道201c的状态时，二号直角梯形块502c-2位于限位条601d的侧面，此时的限位条601d无法阻碍二号直角梯形块502c-2进行上下滑动，当转动螺纹杆202b使得封堵塞202d从横向通道201b的一端运动到另一端的过程中，由于螺纹杆202b位移将带动二号限位杆203d位移，在弹簧502d的弹力作用下，保持卡接框502a和一号卡接齿条602b处于卡接状态，二号限位杆203d和二号推柱502c-1处于抵触状态，二号直角梯形块502c-2将产生水平位移，经过水平位移后将进入均匀排列的限位条601d之间，通过限位条601d来限制连接架501a的上下滑动，保持对温度传感探头400的锁定，随着螺纹杆202b位移距离的增加，一号限位杆203c将抵触一号推柱502a-1，推动锁定件502滑移，一号直角梯形块502a-2将滑动进入均匀排列的限位条601d之间，通过限位条601d来限制连接架501a的上下滑动，直至螺纹杆202b运动一定的距离之后，卡接块502c将和二号卡接齿条603b抵触，螺纹杆202b继续位移使得一号限位杆203c抵触一号推柱502a-1，使得弹簧502d压缩，一号直角梯形块502a-2从限位条601d中滑出，此时解除限位条601d的限位，通过卡接块502c和二号卡接齿条603b的卡接来对连接架501a进行限位，可以在调整封堵件202的位置 时，保持对温度传感探头400的锁定，避免因为蒸汽将温度传感探头400从插套300内顶出的现象出现，由于一号直角梯形块502a-2靠近二号直角梯形块502c-2的一面为倾斜面，二号直角梯形块502c-2靠近一号直角梯形块502a-2的一面为倾斜面，且一号直角梯形块502a-2和二号直角梯形块502c-2相互靠近的一面呈平行状态，一号直角梯形块502a-2和二号直角梯形块502c-2能够和限位条601d之间保持更大面积的接触，同时还能保证卡接框502a和滑动框502b之间的滑移，降低螺纹杆202b位移使得一号直角梯形块502a-2和二号直角梯形块502c-2穿过限位条601d所需要的行程，保障一号直角梯形块502a-2和二号直角梯形块502c-2穿过限位条601d时，至少有其中一个能够和限位条601d之间形成有效的限位，提升对连接架501a的限位效果。
应说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
