Embodiment
With reference to Fig. 1 to 5 of accompanying drawing, shown specific implementation fluid pump 10 of the present invention here, fluid pump 10 has: elongated cylindrical metal cover body 100; From following and metal tubes 200 cover body 100 end-to-ends; Coil 300 around cover body 100; And the long slider 400 in the cover body 100.Cover body 100 has little tubular inlet 110, and tubular inlet 110 face one distal process from it rises so that be connected to water tank by for example flexible pipe.Outlet 210 (inner threaded) are served as in the lower end of pipe 200, so that to for example electric boiler supply water.Cover body 100 and pipe 200 adjacent opened end 120 and 220 and is bonded together by threaded cylindrical joiner 510.Joiner 510 also relies on use pair of screws 522 to support the housing 520 that is used for coil 300.
Slider 400 is supported by cover body 100 and is directed, so that carry out axial sliding movement along opposite direction up and down as piston is in cylinder.Coil 300 is electromagnetic coils, and it acts on the slider of being made by ferromagnetic material 400 and drives slider 400, and this has formed electromechanical assembly, i.e. solenoid together.Slider 400 is located by a pair of upper and lower disc spring 610 and 620, and this is positioned at opposite end place to upper and lower disc spring 610,620, cooperate with the upper and lower end of cover body 100 respectively, thereby make slider 400 static rest on from coil 300 downward biases from the position.
When being encouraged by the ac mains power supply, coil 300 intermittently moves and adjusts upward slider 400 with the effect of antagonistic spring 610 and 620, and thus, slider 400 is driven along cover body 100 reciprocating in vertical direction.
The lower end of slider 400 reduces to become much thin one section, and this section is served as plunger 410.Pipe 200 limits cylindrical cavity 230, and plunger 410 extends into chamber 230 at end 220 places that open of pipe 200.Open end 220 places at this, be provided with seal ring 700, seal ring 700 acts between chamber 230 and the plunger 410, also allows plunger 410 relative chambeies 230 to slide simultaneously.
Slider 400 has through hole 401 along its central axis, and through hole 401 extends up to plunger 410 bottom from the top of slider 400.The hole 401 of passing plunger 410 has the corresponding diameter that reduces, and it serves as the inlet 240 in chamber 230, and what this inlet 240 was arranged on the chamber opens end 220 with interior or with to open end 220 consistent.
Hole 401 allows as a whole to flow down in the inside of slider more than 400, by slider 400 from cover body 100 by 110 water that enter that enter the mouth and enters in the chamber 230.Thereby the bottom side hole of the slider 400 of conjugate foramen 401 402 allows cover body 100 in the inside of slider below 400 and in the internal communication of slider more than 400 and authorized pressure balance.
In chamber 230, the spring-loaded one-way valve that comprises ball 810 act on from below plunger 410 bottom, be the inlet 240 in chamber 230.Used another spring-loaded one-way valve in the bottom in chamber 230, it is used for the outlet 210 in chamber 230, and this one-way valve realizes by valve member 820, and valve member 820 acts on the valve seat 821 that the annular flange flange by the chamber wall provides from below.
Based on the above-mentioned up-and-down movement of the slider 400 under electromagnetic coil 300 effects, plunger 410 carries out pump-absorb action in chamber 230.More particularly, plunger 410 towards the chamber the 230 external induction strokes that make progress slide, water introduced chamber 230 with inlet 240 by chamber 230, wherein, inlet valve 810 is opened simultaneously that outlet valve 820 keeps cutting out.Alternately, plunger 410 slides in the chamber 230 at downward discharge stroke, to force outlet 210 exhaust chambers 230 of water by chamber 230, and wherein, outlet valve 820 is opened then simultaneously that inlet valve 810 is closed now.
The pipe 200 and the suitable area of the opposed face step of clamping member 250, hold it with the real part (substantial part) of clamping whole outer portion 710 and the internal ring portion 720 by clamping seal ring 700 tightly, wherein, the most external of internal ring portion 720 is exposed so that engage pistons 410.
The design of seal ring 700 only allows high pressure water upwards to promote ring 700, and does not have water can walk around the outermost edge that arrives ring 700, thereby and thereby does not have pressure and assemble there and act on the ring 700 and will encircle 700 and push against plunger 410.
By reducing the value of H, can be limited in the circular cross section 721 outer peripheral amounts that flow and act on circular cross section 721 outer peripheral high hydraulic pressure on every side.This can further be avoided Sealing 700 to be extruded against plunger 410 during high hydraulic pressure.
Referring now to Fig. 7 and 7A, Fig. 7 and 7A demonstrate specific implementation another fluid pump of the present invention 10A, fluid pump 10A and above-mentioned first fluid pump 10 have much at one structure and with the operation of identical method, wherein, Deng Xiao part adds suffix letter " A " with identical reference character and represents.
Unique difference is the design of seal ring 700A, and clamping member 250A and pipe end 220A in the face of part together, wherein, describedly clamp and retaining ring 700A in the face of part.Ring 700A has the unitary circular structure equally, and it is roughly T shape by cross section 711A outer portion 710A constitutes with the internal ring portion 720A with spherical cross section 721A.As shown, T shape cross section 711A is positioned at a side and shares common symmetry center axis with another cross section 721A.Spherical cross section 721A be circular or is circle to small part, and slightly thicker than the adjacent portion of T shape cross section 711A.
Thereby seal ring 700A is set up in the wall that is clipped in chamber 230A between clamping member 250A and the pipe end 220A and fixes by making clamped member 250A of its outer portion 710A and pipe end 220A clamp and be clipped in, wherein, make clamping member 250A and pipe end 220A in the face of gripping surface has the cross section of the shape complementarity of the basic and outer portion 710A of shape, so that clamp outer portion 710A securely.Internal ring portion 720A also is received or is received in described in the face of between the gripping surface, and wherein, the most external of internal ring portion 720A is exposed so that engage with the wall slipper seal of plunger 410A.
Compare with first seal ring 700, the shape of the combined cross section of two ring part 710A and 720A is clamped thereby seal ring 700A can be compared safely by the middle part of its thickness that reduces roughly as dumbbell.
Can predict, the invention of this theme can be applicable to comprise various fluids (liquid or the gas) pump of reciprocating type positive-displacement pump, no matter they are direct or indirect process pump, single cylinder or twin cylinder pump, single action or double action pump or kinetic pump.
The present invention only is presented for example, and those skilled in the art can make many other modification and/or changes to described embodiment without departing from the scope of the invention, and scope of the present invention is stipulated in claims.
