Embodiment
For the ease of understanding, below in conjunction with accompanying drawing, by embodiment, technical solutions of the utility model are further described in detail:
As Figure 1-Figure 8, a kind of high-pressure water pump, comprises upper pump casing 1, lower pump body 2, outlet valve 3, inlet valve 4, plunger 41, guide sleeve 42, lining 45, Sealing 46, inlet channel 52 and water outlet 53 and evacuation valve 7.
Upper pump casing 1 is connected by connecting bolt 51 with lower pump body 2, is provided with seal ring 44 between upper pump casing 1 and lower pump body 2, and seal ring 44 plays sealing and anti-leakage effect.
Plunger 41 is sheathed in upper pump casing 1, described plunger 41 threaded upper ends is connected with and knocks cap 5, upper pump casing 1 upper end is provided with adjustment cap 6, the cross sectional area of the work water displacement=working stroke × plunger of described plunger 41, by the size of the adjustable working stroke of adjustment cap 6, when stroke is large, water-outlet quantity is also large, and the explosive thrust of generation is also large, thus controls the size of the nailing dynamics of rifle.
Knock between cap 5 and adjustment cap 6 and be provided with plunger return spring 40, plunger return spring 40 can retract initial position plunger 41.
Be provided with lining 45 and Sealing 46 between upper pump casing 1 and plunger 41, Sealing 46 seals, and can be O type circle or other forms of seal ring and material.The lining 45 material manufacture of wear-resisting and waterproof, is positioned at the top of Sealing 46, and lining 45 effect improves plunger 41 and the coaxality of Sealing 46, to improve the sealing effect of Sealing 46, also reduces the wearing and tearing of Sealing 46.
Be provided with guide sleeve 42 between adjustment cap 6 and plunger 41, described guide sleeve 42 play the guiding role when plunger 41 moves up and down, and adopts wear-resisting material to make to cover 42.
Active chamber 50 is formed between described plunger 41 and upper pump casing 1 and/or lower pump body 2.
Be provided with preloading spring 43 between adjustment cap 6 and upper pump casing 1, preloading spring 43 can strengthen adjustment cap 6 feel.
Lower pump body 2 is provided with outlet valve 3, inlet valve 4 and evacuation valve 7.
Inlet valve 4 connects active chamber 50 by inlet channel 52, and inlet valve 4 is one-way valves, and water can only enter and can not go out.Inlet valve 4 is connected by water pipe and water tank and is formed runner.Inlet valve 4 comprises valve seat 80, spool 81 and Returnning spring 82.Described valve seat 80 has a sealing surface with spool 81, be adjacent to the sealing surface of spool 81 at the precompression lower valve base 80 of Returnning spring 82, when active chamber 50 has degree of vacuum, the active force that spool 81 overcomes Returnning spring 82 under barometric pressure effect is opened, the water of intake pipe is just inhaled in pump working chamber 50, when active chamber 50 has high pressure, valve seat 80 and spool 81 are just close to and are sealed, and water can not be revealed, and plays one-way valve.
Outlet valve 3 connects active chamber 50 by water outlet 53, and outlet valve 3 comprises water intake 60, water outlet 67, valve seat 61, spool 62, position-limited lever 63, Returnning spring 64, valve body 65, locking nut 66 and outlet pipe 68.Valve body 65 one end connecting valve seat 61, the other end connects outlet pipe 68, is provided with spool 62 in valve seat 61, spool 62 one end connects water intake 60, and the other end connects position-limited lever 63, and described position-limited lever 63 is positioned at valve body 65, position-limited lever 63 position-limiting actions, prevent spool from taking off from valve seat.Locking nut 66 is for fastening outlet pipe 68.
Described valve seat 61 and spool 62 are that couple coordinates, and matching gap is 0.001 ~ 0.003mm, and spool 62 has one to lack platform 69, only have spool 62 under water pressure pushing, to lack platform 69 when exposing valve seat 61, and when also just saying that stroke is greater than m, high pressure water could flow out, and m replaces stroke.When water pressure reduces, Returnning spring 64 promotes spool 62 return, now in valve body 65 inner chamber, form a void volume, the water of this void volume must be supplemented by the water in water outlet 67 and outlet pipe 68, the sectional area of this void volume=displacement stroke m × spool 62, the water leaving seldom amount in such outlet pipe 68 pipeline is unlikely to be transmitted by high-temperature part the heat of vaporization come and falls, and when causing impact next time, injection flow rate is inadequate.The water yield that such structure makes high-pressure water pump no matter when get at every turn is impartial, ensures that nailing dynamics is also all the same.
The scarce platform 69 of described spool 62 can have various ways, or cross short slot or spiral short slot.
When there being air in pump working chamber 50, water pump can not normally absorb water work, so air must be discharged.Described evacuation valve 7 is for discharging the air in active chamber 50, and described evacuation valve 7 comprises valve body 70 and spool 71.Be provided with spool 71 in valve body 70, spool 71 is provided with holddown spring 72, and valve body 70 and spool 71 have a sealing cone, back down as long as spool 71 is overcome holddown spring 72 by external force, utilizes vacuum just the air in water pump can be extracted out.Described evacuation valve 7 also can be integrated with the air extractor of outside and be contained on rifle body, more convenient during use.The lower pump body 2 that described evacuation valve 7 is threaded connection water pump is connected with active chamber 50.
During use, when operator hammer beat water pump knock cap 5 time, the water that plunger 41 pressure hits hyperbaric chamber 50 produces high pressure, and high pressure water blast in water pump water outlet valve 3, high-pressure water pipe and intake pipe enter steam power generator (system) produces high temperature and high pressure steam.
