Abstract
The utility model relates to a liquid sampling device, in particular to a sewage sampling valve. The sewage sampling valve comprises a valve body. The upper end of the valve body is connected with a sample feeding pipe and a sample outlet pipe, and a liquid outlet is arranged at the lower end of the valve body. A valve core is sleeved inside the valve body, a control coil is arranged outside the valve body, the control coil is connected with a controller, the valve core is a plastic-sealing iron core, and three supporting points are evenly distributed on the inner wall of the valve body on the lower portion of the valve core. The sewage sampling valve has the advantages that a plastic-sealing iron core structure replaces a traditional glass-sealing iron core structure to be used as the valve core, so that a grinding process is removed, manufacturing is simple, cost is low, and the effects of sealing and throttling are excellent.
Description
Technical field
The utility model relates to a kind of liquid sampler, particularly a kind of sewage sampling valve.
Background technique
In prior art, the electromagnetic valve core of sewage sampling valve adopts the structure of glass capsulation iron core more, in order to strengthen the sealing between spool and valve body, its surface of contact pair frosted structures that adopt more, but frosting technology is a kind of processing technology that bothers very much in producing, and is strict, complex procedures, cost is higher, and sealing and restriction effect not good enough.
Summary of the invention
The utility model is for solving the deficiency in the above-mentioned background technology, a kind of Novel sewage sampling valve is provided, by adopting the plastic seal core structure to substitute traditional glass capsulation core structure as spool, technique is more simple, cost is lower, sealing effect is better, throttling action is more outstanding thereby make.
For achieving the above object, the technical solution adopted in the utility model is:
Sewage sampling valve comprises valve body, and the upper end of valve body is connected with sample feeding pipe and goes out the sample pipe, the lower end is provided with liquid outlet, valve inner cover cartridge spool, and there is control coil the outside of valve body, control coil connects controller, and spool is the plastic seal iron core, and the valve interior wall of spool bottom is evenly equipped with three fulcrums.
Spool is polytetrafluoroethylplastic plastic sealing iron core.
Compared with prior art, the beneficial effects of the utility model are to adopt the plastic seal core structure to substitute traditional glass capsulation core structure as spool, thereby saved frosting technology, make that processing is more simple, cost is lower, and sealing and restriction effect more outstanding.
