The utility model relates to a simplified pipe clamp valve with self inspection function, which comprises a rubber tube, an expansion ring and a air tube seat, a valve body sleeved on the outside of the rubber tube, and an insulation sensor installed on the valve body; a cavity is formed between the inner wall of the valve body and the rubber tube; the air tube seat is installed on the outer wall of the valve body and is communicated with the cavity; the insulation sensor is installed on the valve body through the sensor mounting screw hole, and the inner end is extended into the cavity; the insulation sensor It consists of two conductors that are not in contact with each other, both of which are exposed to the air in the cavity. The utility model is designed for a high-speed railway sewage system, and is also suitable for ordinary passenger trains, large passenger cars and even passenger airplanes. The utility model fundamentally solves the problem that the rubber tube of the pipe clamp valve is damaged and can not be found in time, and reduces the air pollution when the collecting system is applied. The valve body cost of the utility model is far lower than that of the rubber tube, which can be used as a one-time product to reduce the maintenance labor cost. The utility model has the advantages of simple structure and reliable performance, so as to reduce the maintenance workload and use cost of the high-speed railway convenience collection system.

技术介绍
对飞机高铁等客运装备上的集便系统而言,用于排污通道开关控制的管夹阀的工作原理可谓经典;但在产品结构、使用材料和应用过程中仍存在一些问题。首先是体积大、浪费气源、部件多、装配人工成本高;无论是铝合金外壳还是注塑外壳均无例外;由于人们习惯于在机械装备或部件装配过程中采用螺丝或丝扣紧固,管夹阀壳体与胶管间的连接紧固密封也习惯性的采用了这种约定俗成的方式,因此涉及部件较多,壳体就必然会做得很笨重,使用的材料自然就比较多,管夹阀的壳体与胶管间的空间较大完成一次开关动作就需要更多地气源,制造过程中的繁琐工艺也浪费了许多人工成本;另外,管夹阀不论应用于集便系统还是其他系统中,发生胶管破损是迟早的事,如果胶管破损不能及时被发现都会产生不良后果。以应用于集便系统的管夹阀为例:输送粪便过程中在胶管内的压力作用下粪便会透过胶管破损处进入管夹阀压力腔,管夹阀打开过程中压力腔内的压缩空气排大气时,如果压力腔内有渗透进来的粪便,就会随压缩空气排到大气中,排气口若在室内,大便杆菌弥漫在空气中会造成严重污染;由于胶管破损过程很缓慢且很难早期发现,往往当我们发现管夹阀故障时压力空气排气出口的消声器已被粪便堵塞;及时发现管夹阀胶管破损,防止污染意义重大。鉴于此,有必要提供一种结构简单合理、性能稳定可靠、密封性好、故障时能及时发现、价格低廉、具有自检功能的简化管夹阀,从而降低管夹阀制造的材 ...
