As preferably, water inlet flow channel 515 end is provided with spherical water delivering orifice 525 near the side of plug component 53, the radius-of-curvature of this spherical water delivering orifice 525 and the radius of rubber bulb 52 suitable.
embodiment 3
On the basis of embodiment one or embodiment two, SMIS round 519 inside is provided with damping hole 518, damping hole 518 draining aperture be less than the aperture of SMIS round 519, thus when in water inlet flow channel 515, hydraulic pressure is less, water is discharged by damping hole 518, and due to the xsect of damping hole 518 less, the flow that water in water inlet flow channel 515 is arranged outward is less, hydraulic pressure in water inlet flow channel 515 increases faster, thus can make middle spool 58 with outer spool 57 at round place quick separating, pressure release is accelerated in raising.
embodiment 4
On the basis of above-described embodiment, the outline of outer spool 57 is divided into from down to up: lower valve face 571, middle valve face 572, upper valve face 573, on the longitudinal section passing through outer spool 57 central axis, the shape of lower valve face 571 is inside diminishing arcuation para-curve from top to bottom, the shape of middle valve face 572 is straight line and the length of middle valve face 572 is 100 to 400mm, and the shape of upper valve face 573 is the arcuation para-curve outwards increased gradually from top to bottom.For make water flow in runner more smooth and easy, reduce vibration, be easy to outer row, the degree that lower valve face 571 externally tilts is less than the degree that valve face 573 externally tilts.
embodiment 5
On the basis of above-described embodiment, the outside surface of valve body 51 inside surface and outer spool 57 is all piled and is welded with high-chromium alloy wearing layer, and the thickness of built-up welding depends on the needs.
In the chemical composition of high-chromium alloy wearing layer carbon content reach 4 to 5%, chromium content up to 25 to 30%, in its metallographic structure, the volume fraction of Cr7C3 carbonide reaches more than 50%, and macrohardness is HRC56 to 62, and the hardness of chromium carbide is HV1400 to 1800.Because carbonide is formed in the perpendicular distribution of wear direction, even if compare with the casting alloy of hardness with congruent, anti-wear performance is enhanced about more than once, and has good resistance to impact, can bear impact and wearing and tearing that High-Pressure Water causes.In addition, high-chromium alloy wearing layer contains the crome metal of high number percent, therefore makes the outside surface of valve body 51 inside surface and outer spool 57 all have necessarily antirust and corrosion resistance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
