Description

Filtering pressure reducing valve

Technical field

The utility model relates to a kind of filtering pressure reducing valve.

Background technique

Filtering pressure reducing valve in use behind the impurity such as the oil in the pressurized air process two-stage three-segment formula filter removal pressurized air, water, dirt, has improved the working life of reduction valve diaphragm and the precision of adjusting pressure greatly; Because filter element is longer working life; On safeguarding, can repair filter element, decompression member separately, need not integral replacing, practice thrift cost greatly; And present on the market filtering pressure reducing valve; It is all reasonable inadequately that internal structure is provided with, not outstanding to the filter capacity of impurity, can't reach a good filtering effect.

Summary of the invention

The purpose of the utility model is to overcome the defective of existing technology, provide a kind of structure setting more rationally, performance is more outstanding, more stable, the better filtering pressure reducing valve of filter capacity.

For realizing above-mentioned purpose, the utility model adopts a kind of filtering pressure reducing valve, comprises valve gap, valve body, water tumbler, spool, diaphragm unit, relief valve, cyclone blade, manger board, the seat that discharges water, round head bolt, assembly cap, pressure-regulating device, filter core; Said valve gap is arranged on the valve body, links together with the upper end of valve body, and the lower end of water tumbler and valve body links together; The part of controlling mechanism is arranged on the inner chamber of valve gap, and another part of controlling mechanism stretches out valve gap and is formed on the valve gap outside, and diaphragm unit is arranged on the joint of valve gap and valve body; Filter core is fixedly installed on the centre of valve body, and relief valve is arranged on the inner chamber of water tumbler, and the upper end of relief valve is installed in the installation cavity of valve body; The lower end of relief valve is formed in the inner chamber of water tumbler; The top of filter core and relief valve the bottom be connected, said cyclone blade is set on the installation end face of relief valve and filter core, said round head bolt passes manger board; The bottom is connected with the screw of relief valve bottom intermediate portion; The seat that discharges water is arranged on the lower end of water tumbler, is fixed together through discharge water assembly cap and water tumbler, and the lower end of said manger board and filter core links together.

The utility model further is provided with again; Said pressure-regulating device comprises handwheel, screw press, look nut, pressure adjusting spring; Screw press axially is installed on the valve gap through look nut; Said pressure adjusting spring is sleeved on the screw press, and the end top of pressure adjusting spring is located at the lower end surface of look nut, and the other end of pressure adjusting spring withstands on the upper-end surface of diaphragm unit.

In sum; The beneficial effect of the utility model is: through above setting; The internal structure of the utility model becomes more reasonable, and performance of products improves, and is more stable; Simultaneously make that also the filter capacity of product is better, improved the working life and the precision of regulating pressure of reduction valve diaphragm greatly.
