Abstract
The invention relates to a check valve with a filter function. The check valve is characterized by comprising a valve body (1), wherein a valve base (2) is fixed in the valve body (1), an oil way through hole (2.1) is arranged on the valve base (2), a spring base (3) is arranged on the valve base (2), and the bottom of the spring base (3) covers the oil way through hole (2.1). A spring bushing (4) is arranged above the spring base (3), a spring (5) is arranged between the spring base (3) and the spring bushing (4), and the valve base (2), the spring base (3) and the spring bushing (4) are fixed by a bolt (6) which penetrates through the valve base (2), the spring base (3) and the spring bushing (4) from bottom to top. A flange (8) is respectively arranged at the bottom and the top of the valve body (1), a flange through hole (8.1) is arranged on each flange (8), and a filter screen (8.2) is arranged in each flange through hole (8.1). The check valve with the filter function can filter impurities, is not needed to be detached during cleaning, and save labor cost.
Description
Technical field
The present invention relates to a kind of one-way valve, be mainly used in the hydraulic system of machineries such as large excavator, hoist, be used to connect the oil circuit hole of hydraulic machinery, belong to valve technology field with filtering function.
Background technique
Many oilholes in the hydraulic system of machinery such as large excavator, hoist need be connected with other equipment through one-way valve.The break-make that one-way valve can be used for controlling the oil-way system of hydraulic machinery realizes unidirectional conducting.Yet because the oil in the hydraulic machinery constantly flows, wherein adhered to more impurity in various device,, needed to consume a large amount of manual works if large hydraulic equipment is carried out very trouble of disassembly, cleaning.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of one-way valve with filtering function is provided, this one-way valve can impurity screening, avoids disassembly, cleaning, and has saved cost of labor.
The objective of the invention is to realize like this:
The present invention has the one-way valve of filtering function, comprises valve body, and the internal fixation of valve body has valve seat; Have the oil circuit through hole on the valve seat, said valve seat is provided with spring seat, and the bottom of this spring seat covers the oil circuit through hole; The top of spring seat is provided with spring housing, is provided with spring between said spring seat and the spring housing, and said valve seat, spring seat and spring housing fix from running through down through bolt; Said bolt top is provided with locking nut; The bottom and the top of said valve body are equipped with flange, have the flange through hole on the said flange, are provided with filter screen in the said flange through hole.
Compared with prior art, the invention has the beneficial effects as follows:
Filter plate is equipped with in the one-way valve bottom of this this band filter screen of one-way valve with filtering function, and the impurity of the filter screen on the filter plate through hole in can filter oil has been avoided the disassembly, cleaning to large hydraulic machinery, has saved manual work.
Description of drawings
Fig. 1 has the cross-sectional view of the one-way valve of filtering function for the present invention.
Fig. 2 has the worm's eye view of the one-way valve of filtering function for the present invention.
Wherein: valve body 1, valve seat 2, oil circuit through hole 2.1, spring seat 3, spring housing 4, spring 5, bolt 6, locking nut 7, flange 8, flange through hole 8.1, filter screen 8.2.
Embodiment
Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of one-way valve with filtering function, comprise valve body 1; The internal fixation of valve body 1 has valve seat 2, has oil circuit through hole 2.1 on the valve seat 2, and said valve seat 3 is provided with spring seat 3; The bottom of this spring seat 3 covers oil circuit through hole 2.1, and the top of spring seat 3 is provided with spring housing 4, is provided with spring 5 between said spring seat 3 and the spring housing 4; Said valve seat 2, spring seat 3 and spring housing 4 fix from running through down through bolt 6, and said bolt 6 tops are provided with locking nut 7, and locking nut 7 is used for bolt 6 fixing; The bottom of said valve body 1 and top all are fixed with flange 8; Said flange 8 is used for one-way valve is fixed on the flange of oil pipe and hydraulic machinery, has three flange through holes 8.1 on the said flange 8, is provided with filter screen 8.2 in the said flange through hole 8.1.
When one-way valve led to oil, oil got into from the one-way valve bottom, and passes the oil circuit through hole 2.1 of valve seat 2, just can lead to oil after spring seat 3 is backed down.After logical oil finished, spring 5 resetted spring seat 3, makes spring seat 3 cover oil circuit through hole 2.1.
Claims (1)
1. one-way valve with filtering function, it is characterized in that: it comprises valve body (1), the internal fixation of valve body (1) has valve seat (2); Have oil circuit through hole (2.1) on the valve seat (2); Said valve seat (3) is provided with spring seat (3), and the bottom of this spring seat (3) covers oil circuit through hole (2.1), and the top of spring seat (3) is provided with spring housing (4); Be provided with spring (5) between said spring seat (3) and the spring housing (4); Said valve seat (2), spring seat (3) and spring housing (4) fix from running through down through bolt (6), and said bolt (6) top is provided with locking nut (7), and the bottom of said valve body (1) and top are equipped with flange (8); Have flange through hole (8.1) on the said flange (8), be provided with filter screen (8.2) in the said flange through hole (8.1).
