A circular ladder-shaped insertion end is arranged at the bottom of the transfer pipe, and a thread is arranged at the top of the transfer pipe, and the transfer pipe is fixed at one end of the pipe through the insertion end; a probe rod is inserted into the pipe at the transfer pipe, and an O-shaped sealing ring is sleeved in the middle of the probe rod, and the O-shaped sealing ring is opposite to the inner wall of the pipe; and a supporting block is fixed at the top of the probe rod to support the pipeline. A nut corresponding to the top radius of the nozzle is arranged under the block, and one end of the nut is fixed with the supporting block; the outer diameter of the nozzle is larger than the radius of the probe, and a pressure relief gap is formed between the nozzle and the probe rod. Because the pressure relief gap is set, the thrust of high pressure water on the salt probe of marine boiler is reduced, and the sudden explosive growth is avoided when the salt probe of marine boiler is pulled out, the maintenance personnel can hold the salt probe of marine boiler tightly during the process of pulling out the salt probe of marine boiler, thus preventing the high pressure water from supplying the salt probe of marine boiler with very high pressure water. The large kinetic energy makes it earn out of the maintenance personnel and hit the maintenance personnel.

一种船用锅炉盐分探头结构
本新型涉及一种盐分检测装置,尤其是一种船用锅炉盐分探头结构。
技术介绍
船用锅炉盐分探头是用于检测船用锅炉中的盐分浓度的。现有的船用锅炉盐分探头如图2所示,包括底端设有环状阶梯形的插接端、顶端有螺纹的转接管3,转接管3通过环状阶梯形的插接端固定地与管道5插接;探测杆1其中部套有O形密封圈2,其顶部固接有一抵持块,在抵持块下方设置一个与转接管顶端相适的螺母4,螺母与抵持块固接。现有技术的缺陷在于,在工作人员检修船用锅炉盐分探头时,需拧开螺母后将整个船用锅炉盐分探头拆出后进行检修操作。而管道内的水压较高,特别是在工人拉出船用锅炉盐分探头的过程中,让出了管道与固定螺纹轴之间的间隙空间,水进入了该间隙空间,对船用锅炉盐分探头产生推力,致使在工人将船用锅炉盐分探头拉动至刚好脱离管道的瞬间,高压水喷涌而出,其动能传递给脱离了限位装置的船用锅炉盐分探头,容易使船用锅炉盐分探头由于高压水传递的动能而飞出,对工人的人身安全造成严重的威胁。
技术实现思路
本技术旨在给出一种船用锅炉盐分探头结构,减少在拆卸时高压水对船用锅炉盐分探头的冲击力,避免船用锅炉盐分探头被高压水冲击击飞甚至击中检修人员,从而保障检修人员的人身安全。一种船用锅炉盐分探头结构,包括转接管,转接管底端设有环状阶梯形的插接端、转接管顶端设有螺纹,转接管通过插接端与管道的一端固接;探测杆在转接管处插入到管道内,探测杆中部套有O形密封圈,且O形密封圈与管道内壁相抵;探测杆顶部固设有抵持块,在抵持块下方设置一个与转接管顶端半径相适的螺母,螺母的一端与抵持块固接;转接管的外径大于探测头的半径,在转接管 ...
