Accompanying drawing explanation
Figure 1 shows that the generalized section of existing one-way valve;
Figure 2 shows that the structural representation of the jetting machine in the utility model one embodiment;
Figure 3 shows that the thin portion enlarged view of the one-way valve part of Fig. 2 mesohigh washing machine.
Embodiment
In order to more understand technology contents of the present utility model, institute's accompanying drawings is coordinated to be described as follows especially exemplified by specific embodiment.
Referring to Fig. 2 and Fig. 3.Figure 2 shows that the structural representation of the jetting machine in the utility model one embodiment; Figure 3 shows that the thin portion enlarged view of one-way valve 21 part of Fig. 2 mesohigh washing machine.
First, one-way valve 21 comprises valve pocket 201, outlet pipe spring 202, first seal ring 203, valve seat 204 and the second seal ring 205.Valve pocket 201 outer race has the first seal ring 203.Valve pocket 201 is enclosed within outside valve seat 204, and the second seal ring 205 is arranged between valve seat 204 and valve pocket 201, plays seal action.Outlet pipe spring 202 is supported on valve seat 204, supports valve pocket 201 by valve seat 204 to A direction.
One-way valve 21 more comprises spool 206, steel ball 207 and valve pocket spring 208.Spool 206, steel ball 207 and valve pocket spring 208 are arranged in valve pocket 201, and valve pocket spring 208 abuts spool 206 and valve pocket 201, and steel ball 207 is arranged between spool 206 and valve seat 204.Valve seat 204 has water passage hole 209.Normal state lower valve sleeve spring 208 withstands steel ball 207 by spool 206, and the water passage hole 209 on valve seat 204 is blocked closedown by steel ball 207.
First water cavity 211 of jetting machine 2 and the second water cavity 212 are arranged on one end of valve pocket 201, and the 3rd water cavity 213 is arranged on the other end of valve pocket 201.Jetting machine 2 also comprises relief valve valve rod 214, in order to regulate the hydraulic pressure in the second water cavity 212.Jetting machine 2 also comprises outlet pipe 20.
Jetting machine operationally, the pressure of the first water cavity 211, second water cavity 212 and the 3rd water cavity 213 is equal, the hydraulic pressure at steel ball 207 two ends is equal, and valve pocket spring 208 withstands steel ball 207 by spool 206, and the water passage hole 209 on valve seat 204 is blocked closedown by steel ball 207.
When jetting machine 2 is in pass gun state, the relief valve valve rod 214 in pump cover produces action, makes the second water cavity 212 internal pressure change and reduce, and the hydraulic pressure of steel ball 207 both sides in one-way valve 21 is changed, becomes unequal.Hydraulic pressure now in the 3rd water cavity 213 is greater than the hydraulic pressure in the second water cavity 212, namely when the hydraulic pressure of spool 206 side of steel ball 207 is less than the hydraulic pressure of outlet pipe spring 202 side, hydraulic pressure in 3rd water cavity 213 overcomes the elastic force of valve pocket spring 208, back down steel ball 207 pressure release, thus reach to the effect of jetting machine 2 pressure release.When the elastic force of the hydraulic pressure in the hydraulic pressure in the 3rd water cavity 213, the second water cavity 212 and valve pocket spring 208 reaches balance, the water passage hole 209 on valve seat 204 is blocked closedown by steel ball 207 again.
One-way valve 21, in above-mentioned working procedure, serves the effect of non-return effect and reduction valve, has enriched the function of one-way valve in prior art, has had more practicability.
Although the utility model with preferred embodiment disclose as above, so itself and be not used to limit the utility model.Have in the utility model art and usually know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on those as defined in claim.
