Described valve gap 7 is arranged on the inner chamber 31 of sealed cylinder block 3 on cylinder body 3; Telescopic container 5 is provided with in described inner chamber 31; Described Telescopic container 5 has cavity; One end and the valve gap 7 of described Telescopic container 5 are tightly connected, and the other end seals; Described valve gap 7 is provided with the oil connection 8 being communicated with Telescopic container 5 cavity.
Described filler opening 34 is provided with and refers to that mode that feed liquor one-way valve 1 connects is flow into miniature LNG blower pump for pipeline inner chamber 31 from miniature LNG blower pump for pipeline outside for making direction of flow by inner chamber 31 externally to the feed liquor one-way valve 1 that inner chamber 31 inside is communicated with.
Described oil outlet 35 is provided with and refers to that the Placement of fluid one-way valve 2 is that to flow out miniature LNG blower pump for pipeline from miniature LNG blower pump for pipeline inner chamber 31 outside for making direction of flow by inner chamber 31 inside to the fluid one-way valve 2 of inner chamber 31 ft connection.
In working procedure: as shown in Figure 3, first need the fluid by once pressing to enter in inner chamber 31 by feed liquor one-way valve 1, described fluid refers to liquid or gas; Then hydraulic oil is passed into by the oil connection 8 that valve gap 7 is arranged, hydraulic oil flows in the cavity of Telescopic container 5, because one end of Telescopic container 5 and valve gap 7 are tightly connected, the other end seals, therefore when the cavity inherence of Telescopic container 5 is filled with hydraulic oil, Telescopic container 5 expands, and Telescopic container 5 extends the fluid be squeezed in inner chamber 31, thus realizes pressurization to the fluid in inner chamber 31.Fluid after pressure increase flows out inner chamber 31 by oil outlet 33 through oil outlet one-way valve 2; Thus realize the supercharging of convection cell.Due to the stretchability that Telescopic container 5 has, after pressurization completes; Hydraulic oil or gas stop passing in Telescopic container 5 cavity; Hydraulic oil or gas are by oil connection 8 oil return simultaneously, and in Telescopic container 5, hydraulic oil or gas reduce, and Telescopic container 5 can be retracted to reset condition, and now fluid enters into inner chamber 31 by feed liquor one-way valve 1, after being full of inner chamber 31; Oil connection 8 passes into hydraulic oil, repeats the process that convection cell carries out pressurizeing.Telescopic container 5 expands and recovers once, completes a pulse-pressure of convection cell.The space of storing fluid in inner chamber 31 is reduced by the expansion of Telescopic container 5, thus realize the pressurization of convection cell, avoid when realizing convection cell pressurization by the mobile space reducing storing fluid of piston in traditional plunger pump, sealing is needed between piston and the inwall of inner chamber of cylinder block, and can relative sliding.Therefore high requirement is higher, and working life is short simultaneously.The utility model adopts shell Expansion container 5, can increase the service life, and reduces manufacture cost.
In above process can by regulating the pressure of hydraulic oil or the gas entered in Telescopic container 5 thus regulating miniature LNG blower pump for pipeline inner chamber 31 inner fluid applied pressure; Thus make the pressure of inner chamber 31 inner fluid reach the value needing adjustment.
Miniature LNG blower pump for pipeline described in the utility model is by arranging Telescopic container 5 in the inner chamber 31 of cylinder body 3 in sum, by thinking to pass in Telescopic container 5 gas or liquid with pressure, Telescopic container 5 is expanded, thus the gap between Telescopic container 5 and inner chamber 31 is reduced, fluid in compression inner chamber 31, thus realize the pressurization of convection cell.Pressure provides solution or atmosphere storage in Telescopic container 5 simultaneously, and avoiding pressure provides solution or gas leakage in pressurized fluid, and convection cell damages.This miniature LNG blower pump for pipeline, structure is simple, simple to operate; Liquid driven or gas-powered can be realized, driving mode variation simultaneously.Therefore the miniature LNG blower pump for pipeline described in this practicability, can save the manufacture cost of miniature LNG blower pump for pipeline, simplify the operation, and improves the adaptability of miniature LNG blower pump for pipeline, extends working life.
In order to improve pumping efficiency, make pressurization evenly.Further, piston 4 is provided with in described inner chamber 31; Described piston 4 is slidably matched with inner chamber 31; Described Telescopic container 5 is between piston 4 and valve gap 7, and described Telescopic container 5 one end and valve gap 7 are tightly connected, and the other end and piston 4 are tightly connected.
Piston 4 is provided with in described inner chamber 31; Described piston 4 and inner chamber 31 are slidably matched and refer to that piston 4 can move in inner chamber 31, and and gapless between the inwall of inner chamber 31.
Telescopic container 5 is provided with between described piston 4 and valve gap 7; Described Telescopic container 5 has cavity; Described Telescopic container 5 one end and valve gap 7 are tightly connected, and the other end and piston 4 are tightly connected and refer to that one end of Telescopic container 5 is connected with valve gap 7, and the cavity of this end is sealed by valve gap 7; The other end is connected with piston 4, and the cavity of the other end is sealed by piston 4.The other end that one end of described Telescopic container 5 is connected with valve gap 7 is connected with piston 4; Therefore can by the motion of the extension and contraction control piston 4 of Telescopic container 5; By the motion of control piston 4, the gap length between the bottom of control piston 4 and inner chamber 31.Thus regulate the pressure entering the fluid of miniature LNG blower pump for pipeline inner chamber 31.
If piston 4 is not connected with Telescopic container 5; So when miniature LNG blower pump for pipeline is by when placing as shown in Figure 3, piston 4 can self gravitation do with under contact with the bottom of inner chamber 31, when fluid enters into inner chamber 31 by feed liquor one-way valve 1, the gravity of piston 4 can apply a pressure by automatic convection cell; Therefore this pressure cannot control.Make fluid cannot keep the pressure of self after entering miniature LNG blower pump for pipeline simultaneously.In order to avoid there is above-mentioned situation, be therefore provided with Telescopic container 5, thus piston 4 is connected with valve gap 7, between ensureing bottom piston 4 and inner chamber 31, there is a primary clearance.Thus ensure that fluid pressure after entering inner chamber 31 remains unchanged, just can implement supercharging when starting miniature LNG blower pump for pipeline.
