Description
Technical field
The utility model relates to the technical field of valve, is specifically a kind of mangetic core assembly for automatically controlled backwash filter.
Background technique
Backwash filter, is that a kind of filter screen that utilizes directly tackles impurity in water, removes water body recovery technology, particulate matter, reduce turbidity, reduce the generations such as system dirt, bacterium algae, corrosion, with the precision equipment purified water and other equipment of protective system normally work.The shortcoming that the automaticity brought due to manually operated backwash filter is low, labor intensity is large, therefore, the backwash filter that coal mine underground support uses, normally adopts automatically controlled backwash filter.If publication number disclosed on State Intellectual Property Office website is the automatic backwashing filter of CN102100984A, it discloses in valve body and main valve plug assembly, element kit, fluid joint are installed, wherein main valve plug assembly comprises valve pocket, spring, valve rod and piston, and main valve plug assembly integrally plug connector loads valve pocket.Its working procedure is that valve stem slides is connected in valve pocket, and the upper end of valve rod is fixedly connected with piston, and form the valve of opening or closing working hole between valve rod and valve pocket, spring housing is connected on valve rod and the two ends of spring and pushes against with piston and valve pocket respectively.But the mangetic core assembly of the electric reverse flush filter of this structure exists following problem: move down until blocked by liquid entering hole due to piston, valve closing, when working hole returns liquid, spring is what to be in by the state compressed; When valve is opened again, piston stops toward pressing down, and valve rod will move up gradually under the effect of the restoring force of spring, until spring-return is to original state; Therefore, after using for a long time, spring is tired gradually, will produce spring failure or the phenomenon slowly that resets, thus the response making mangetic core assembly not in time, causes the normal working performance affecting whole filter.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of valve rod to respond in time, thus ensures the mangetic core assembly for automatically controlled backwash filter that mangetic core assembly normally works.
For solving the problems of the technologies described above, the mangetic core assembly for automatically controlled backwash filter that the utility model provides, comprise valve pocket, valve rod, spring and piston, valve stem slides is connected in valve pocket, piston is slidably fitted in one end of valve pocket, and form pistons work chamber between piston and valve pocket and valve rod, spring housing is connected on one end of valve rod and is positioned at pistons work chamber, one end and the piston of spring push against, and the other end and valve pocket push against; The sleeve side wall at described pistons work chamber place is provided with at least one liquid-through hole, and one end of this liquid-through hole is communicated with near the pistons work chamber at the bottom of chamber, and the other end is communicated with the liquid entering hole of valve pocket in valve pocket outside.
Described valve pocket has annular groove on one end outer circle wall of piston, and annular groove is wherein the oblique sidewall expanded outwardly away from a sidewall of valve pocket end; Described liquid-through hole is the through hole tilted, and one end of liquid-through hole is positioned on oblique sidewall.
The quantity of described liquid-through hole is four, and along the circumferential direction uniform.
Described valve pocket is formed by connecting by upper valve sleeve and lower valve sleeve, and piston is slidably fitted in upper valve sleeve, and liquid-through hole is also positioned on upper valve sleeve, and valve rod and upper valve sleeve sliding connection also form valve with lower valve sleeve.
After adopting above structure, the utility model compared with prior art, have the following advantages: owing to being provided with liquid-through hole on the valve pocket in pistons work chamber, and liquid-through hole is communicated with liquid entering hole, therefore, when the valve is open, not only at liquid entering hole feed liquor, and liquid also enters pistons work chamber from liquid-through hole simultaneously, thus the fluid pressure in pistons work chamber is raised, force piston to move up, serve the effect of secondary spring and make piston revert to initial position; Therefore, make the response of valve rod at the right time, sensitive, also extend the working life of spring simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the mangetic core assembly of automatically controlled backwash filter.
Wherein: 1, piston; 2, spring; 3, valve rod; 4, valve pocket; 5, liquid entering hole; 6, annular groove; 7, pistons work chamber; 8, liquid-through hole; 9, oblique sidewall.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
The structural representation that the utility model is as shown in Figure 1 used for the mangetic core assembly of automatically controlled backwash filter is known, it comprises valve pocket 4, valve rod 3, spring 2 and piston 1, valve rod 3 is slidably connected in valve pocket 4, piston 1 is slidably fitted in one end of valve pocket 4, pistons work chamber 7 is formed between piston 1 and valve pocket 4 and valve rod 3, spring 2 is socketed in one end of valve rod 3 and is positioned at pistons work chamber 7, and one end and the piston 1 of spring 2 push against, and the other end and valve pocket 4 push against.Valve pocket 4 sidewall at described pistons work chamber 7 place is provided with at least one liquid-through hole 8, and one end of this liquid-through hole 8 is communicated with near the pistons work chamber 7 at the bottom of chamber, and the other end is communicated with the liquid entering hole 5 of valve pocket 4 in valve pocket 4 outside.
Described valve pocket 4 has annular groove 6 on one end outer circle wall of piston 1, and annular groove 6 is wherein the oblique sidewall 9 expanded outwardly away from a sidewall of valve pocket 4 end.Described liquid-through hole 8 is the through hole tilted, and one end of liquid-through hole 8 is positioned on oblique sidewall 9.
