Abstract
The utility model discloses a water drain valve core of a filter, which comprises a valve rod. The valve rod comprises the front portion, the middle portion and the rear portion which are integrated. The front portion and the rear portion are both in a cylindrical shape, and the middle portion is a taper-shaped platform. An annular boss and an annular groove are arranged on the ring wall of the front portion of the valve rod, the annular groove is located outside the annular boss, threads are arranged on the ring wall of the annular boss, and a seal ring is installed in the annular groove in sleeved mode. The water drain valve core of the filter is simple in structure, reasonable in design and simple and convenient in manufacturing process, enhances sealing performance through the effect of the seal ring, and meets using requirements of enterprises.
Description
Technical field
The utility model relates generally to the filter cleaner technical field, relates in particular to a kind of filter cleaner with the spool that discharges water.
Background technique
Filter cleaner includes air-strainer, oil filter and fuel filter.
Air-strainer is arranged in engine aspirating system, the assembly that it is made up of the filter component of one or several clean air.It mainly acts on is that filtering will get into objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.
Oil filter is arranged in engine lubrication system.Its upper reaches are oil pump, and downstream are to need each lubricated component in the motor.Its effect is to carrying out filtering from objectionable impurities in the machine oil of oil sump, with kinematic pair such as the engine oil supplying bent axle of cleaning, connecting rod, camshaft, pressurized machine, piston rings, plays lubricated, cooling, cleaning action, thereby prolongs the life-span of these component.
Fuel filter is on the pipeline that is connected between fuel pump and the throttle valve body filler opening.The effect of fuel filter is to remove solid sundries such as being contained in iron oxide in the fuel oil, dust, prevents that oil-fired system from stopping up.
The structure of each parts will have influence on the usability of filter cleaner in the filter cleaner.Such as filter cleaner is with the spool that discharges water.
The model utility content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of filter cleaner rational in infrastructure with the spool that discharges water.
The utility model is realized through following technological scheme:
A kind of filter cleaner includes valve rod with the spool that discharges water, and it is characterized in that: valve rod includes front portion, middle part and the rear portion of one; Said front and rear is cylindrical; Said middle part is the taper platform, and the anterior ring wall of said valve rod is provided with annular boss and annular groove, and annular groove is positioned at the outside of annular boss; The ring wall of said annular boss is provided with screw thread, is set with seal ring in the annular groove.
A kind of filter cleaner is characterized in that with the spool that discharges water: said valve rod middle part diameter dimension is greater than the anterior diameter dimension of valve rod, and the anterior diameter dimension of valve rod is greater than valve rod rear portion diameter dimension.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, and preparation process is simple and convenient, and the effect through seal ring has strengthened sealability, satisfied the user demand of enterprise.
