Embodiment
embodiment 1:
As shown in Figure 1, the utility model provides a kind of self-cleaning cone shaped one-way valve, comprises valve seat 5 and covers on the valve bonnet 8 be connected on valve seat 5 and with valve seat 5, forming hollow cavity between valve seat 5 and valve bonnet 8, the bottom of valve seat 5 offers conical through-hole 10, and the top board of valve bonnet 8 offers liquid outlet 9;
Valve rod 7 is provided with in hollow cavity, valve rod 7 is arranged with spring 6, the top board of valve bonnet 8 is run through in one end of valve rod 7, one end is connected with valve plate 1 and scrubbing plate 3 by screw 4 in addition, valve plate 1 is between valve rod 7 and scrubbing plate 3, the surface contact of valve plate 1 and scrubbing plate 3 and conical through-hole 10 or be separated, the diameter of scrubbing plate 3 is greater than the maximum diameter of conical through-hole 10.
The working principle of the self-cleaning cone shaped one-way valve that the utility model provides is:
The Compress Spring 6 when valve plate 1 is subject to upper liquid suction or lower liquid thrust, valve plate 1 and scrubbing plate 3 up, scrubbing plate 3 slightly extrudes rear arrival valve seat 5 top by valve seat 5, and passage is opened, and liquid is entered by conical through-hole 10, discharges from liquid outlet 9.
When valve plate 1 upper liquid suction be less than spring 6 downwards spring-back force or be subject to lower liquid suction time valve plate 1 and scrubbing plate 3 descending, pathway closure.The diameter of scrubbing plate 3 is greater than the maximum diameter of conical through-hole 10, and time descending, scrubbing plate 3 rubs with the conical through-hole 10 of valve seat 5, scrubbing plate 3 pairs of valve seats 5 are cleared up, and by dirt removal, valve rod 7 continues descending, until conical through-hole 10 close contact of valve plate 1 and valve seat 5, passage is thoroughly closed.
It should be noted that, as shown in Figure 1, the one side that valve plate 1 contacts with conical through-hole 10 is inclined-plane, and when valve rod 7 drives valve plate 1 up or descending, this inclined-plane can increase valve plate 1 and the area of contact of conical through-hole 10, ensures sealability; The shape of scrubbing plate 3 is the cylindrical body that there is radian centre, the similar drum type of its shape, when scrubbing plate 3 contacts with conical through-hole 10, can ensure the sealability of valve seat 5 and scrubbing plate 3.
This self-cleaning cone shaped one-way valve that the utility model provides, is applicable to the self-cleaning type cone shaped one-way valve of various oil hydraulic pump, can foreign matter on automated cleaning valve seat, effective guarantee valve plate and valve seat can not single-contact for a long time, reduce fixed position wearing and tearing, guarantee one-way valve sealing, extend valve working life.
embodiment 2:
On the basis of embodiment 1, be connected with locating shoulder 2 between described valve rod 7 and valve plate 1, this locating shoulder 2 can position spring 6, also can prevent moving up and down and causing misaligning of valve plate 1 of valve plate 1 simultaneously.
