Abstract
The utility model relates to a flow pressure controller for a mini air compressor. A main body of the flow pressure controller is in an H-shaped layout, the right part of the main body comprises a knob, a valve rod, a pressing nut, a valve seat and a pressure switch, the left part of the main body comprises a venting connector, the left part is connected with the right part through a sealed air pipe, and a needle valve is arranged in the air pipe. The knob is fastened at the upper end of the valve rod with the lower end in a cone shape, and a cone head part abuts against the right end of the needle valve. A screw thread is arranged in a middle section of the valve rod and is matched with the surrounding pressing nut, the pressing nut is in threaded fit with the valve seat, and a returning spring is arranged at the left end of the needle valve. The lower portion of the valve seat is connected with the pressure switch, and the pressure switch is turned on and turned off through pressure of compressed air exhausted out of the air compressor. The flow pressure controller is small in size and can be matched with the mini air compressor. Due to the fact that a pressure regulating valve or a flow control valve is combined together, the mini air compressor is convenient to carry. Simultaneously, due to the fact that the cone head part squeezes the needle valve, flow and pressure can be adjusted freely, the adjusting range is wide, precision is high, and the flow pressure controller is stable in overall performance and compact in structure.
Description
Technical field
The utility model is to control the controlling device that air compressor goes out throughput and pressure for regulating, and especially refers to a kind of mini air compressor flow pressure controller.
Background technique
Along with the needs of industry developments such as advertising painting, workpiece spray paint, pneumatic control, small-sized or micro-air compressor is extensive application more and more.Because its volume is little, be easy to carry, can move use.So welcome by the operator.Because some special occasions needs the littler air compressor of volume, repairing needs painting as the field maintenance automobile, when some outdoor facility is maintained, wall advertisement air brushing etc., need light air compressor and small-sized spray gun supporting, so industry requirement has the littler air compressor of a kind of volume, be commonly called as mini air compressor flow pressure controller.Because the microminiaturization of air pump, so require supporting with it flow pressure controller also to want microminiaturized, that is to say that claimed structure compactness, volume are small and exquisite, the product that pressure regulation and control flow unite two into one.
The model utility content
The purpose of this utility model is to provide a kind of supporting compact structure, volume with it small and exquisite to mini air compressor, mini device---the air pump flow pressure controller that pressure regulation and control flow unite two into one can make complete machine be more suitable for being easy to carry, move and use.
The technological scheme of the utility model technical solution problem is: mini air compressor flow pressure controller, its main body is H shape layout, the right half of described main body is knob, valve rod, clamping nut, valve seat and pressure switch from top to bottom successively, the left half of described main body is air outlet adapter, tracheae with sealing in the middle of the two-part of the left and right sides connects, and is provided with needle-valve in described tracheae.Described knob is fastened on the valve rod upper end, and described valve rod lower end is tapered, and its cone head part withstands the right-hand member of needle-valve; Described valve rod stage casing has spiral shell strand, cooperates with on every side clamping nut, and described clamping nut and valve seat closely cooperate with screw thread, and the needle-valve left end heads on a reciprocal Returnning spring that moves of control needle-valve.
Described valve seat bottom connects pressure switch, and the compressed air pressure control that described pressure switch is discharged by air compressor opens and closes.
Be provided with seal ring between described valve rod and the valve seat.
Characteristics of the present utility model are that volume is small and exquisite, can be complementary with mini air compressor.And pressure regulator valve or flow control valve are combined, save one of them, the boundary dimension of mini air compressor complete machine is dwindled, thereby be more convenient for carrying.While is because of the mode with conehead extruding needle-valve, but the equal free adjustment of flow and pressure, and regulation range is wide, precision is high; Overall performance is stable, compact structure.
Description of drawings
Fig. 1 is the vertical cross-sectional schematic of the utility model;
Each title and numbering among the figure: 1-knob, 2-valve rod, 3-clamping nut, 4-seal ring, 5-needle-valve, 6-valve seat, 7-pressure switch, 8-Returnning spring, 9-air outlet adapter.
Embodiment
As shown in Figure 1: mini air compressor flow pressure controller, its main body is H shape layout.The right half of main body is knob 1, valve rod 2, clamping nut 3, valve seat 6 and pressure switch 7 from top to bottom successively.The left half of main body is air outlet adapter 9, and the tracheae with sealing in the middle of the two-part of the left and right sides is communicated with, and is provided with needle-valve 5 in tracheae.Knob 1 is fastened on valve rod 2 upper ends, and valve rod 2 lower ends are tapered, and its cone head part withstands the right-hand member of needle-valve 5.Valve rod 2 stage casings have spiral shell strand, cooperate with on every side clamping nut 3, and clamping nut 3 and valve seat 6 usefulness screw threads closely cooperate.Needle-valve 5 left ends head on the back and forth Returnning spring 8 of operation of a control needle-valve 5.Valve seat 6 bottoms connect pressure switch 7, and the compressed air pressure control that pressure switch 7 is discharged by air compressor opens and closes.Between valve rod 2 and valve seat 6, be provided with seal ring 4.
Once working principle of the present utility model and using process are described below: pressurized air enters pressure switch 7 from tracheae, reed in the pressure switch 7 is backed down, enter valve seat 6 inner chambers, use knob 1 spinning valve rod 2 this moment, valve rod 2 moves downward, and the conehead extruding needle-valve 5 of valve rod 2 ends makes needle-valve 5 bars to left movement, the needle point of needle-valve 5 and the gap smaller of valve port, air mass flow diminishes.On the contrary, knob 1 turn in the other direction, valve rod 2 moves upward, and the conehead of valve rod 2 ends loosens needle-valve 5 extruding, and needle-valve 5 moves right under Returnning spring 8 promotes, and makes needle point with big with the gap change of valve port, and it is big that air mass flow also becomes thereupon.
