Detailed description of the invention
With detailed description of the invention, the utility model is further described below in conjunction with the accompanying drawings.
In embodiment as shown in Figures 1 to 4, a kind of press type liquid nozzle, including the 1st, the pump housing carries
The 2nd, the upper shield of internal thread is in combination lid above upper shield the 21st, with the piston rod 31 of bar cavity, institute
Stating upper shield to be set on the pump housing, having in tubulose road in conjunction with lid and be relatively fixed with the pump housing, piston rod passes through
In conjunction with road in the tubulose of lid, piston rod upper end is provided with the elbow nozzle 4 connecting with bar cavity, bar hollow
It is provided with out liquid check valve, feed liquor check valve in chamber, go out liquid check valve and be in above feed liquor check valve, the pump housing
Inside being provided with the piston seat 32 with seat cavity, pump housing lower end is provided with the suction pipe 11 connecting with seat cavity,
Piston rod includes that the 311st, tube rod section is in the flared section of tube rod section lower end the 312nd, for terminating under lid with combining
Touch the sealing 313 sealing, sealing connecting tube bar segment and flared section, flared section and pump housing madial wall it
Between slipper seal coordinate, be provided with spring 33 between sealing and piston seat, the pump housing be provided with at least one lead to
Pore, passage present position is higher than present position, flared section lower end.So-called slipper seal coordinates, it is simply that
Can relatively slide, keep again sealing effectiveness, as between cylinder block of the prior art and oil cylinder piston
Cooperation, coordinating between cylinder block with cylinder piston, broadly fall into slipper seal coordinate.
Described elbow nozzle includes bleed pipe the 41st, straight tube 42, and piston rod upper end is connected with straight tube, on straight tube
End connects with bleed pipe, and straight tube lower end connects with bar cavity, and straight tube lateral wall is provided with pipe external screw thread,
It is provided with the lid internal thread mating with pipe external screw thread in conjunction with road in the tubulose of lid.When not needing to use this practicality
When novel, or before the utility model does not also break a seal, in straight tube can be allowed to screw in tubulose, road is (now outside pipe
Screw thread and lid screw-internal thread fit), such that it is able to allow elbow nozzle be fixed.
Described go out liquid check valve include closing in pipe the 51st, for blocking the upper reverse blocking pearl 52 of upper closing in pipe, on
In the pipe of closing in pipe, bore is gradually increased from the bottom to top, between upper closing in pipe lateral wall and bar cavity inwall
It is tightly connected；Feed liquor check valve include lower closing in pipe the 61st, for blocking the lower reverse blocking pearl 62 of lower closing in pipe,
The bore of lower closing in pipe is gradually increased from the bottom to top, close between lower closing in pipe lateral wall and bar cavity inwall
Envelope connects.
Being provided with the gag lever post 421 for limiting upper reverse blocking pearl displacement in described straight tube, gag lever post is in
Above upper reverse blocking pearl, gag lever post lower end is stretched in bar cavity；It is provided with in piston seat for limiting lower reverse blocking
The limit body 321 of pearl displacement, limit body is in above lower reverse blocking pearl.Upper reverse blocking pearl at most rises to
Contact gag lever post lower end, lower reverse blocking pearl at most rises to contact limit body, such that it is able to prevent on reverse blocking pearl
Rise apart from excessive, can the stability of the effective guarantee course of work.
Upper shield is enclosed within liquid container, and available internal thread is connected with liquid container.During work, press down
Elbow nozzle, drives and presses under piston rod, and now pump body space reduces, and pressure increases, pump body
Liquid be extruded the pump housing, due to the existence of lower reverse blocking pearl and lower closing in pipe, cause the liquid cannot be from the pump housing
Enter liquid container, so liquid can only upwards be washed open reverse blocking pearl, (be squeezed by straight tube, bleed pipe ejection
Go out).And after discharging elbow nozzle, under the action of the spring, piston rod resets, now pump body space increases
Greatly, air pressure reduces, thus has negative-pressure sucking, due to the existence of upper reverse blocking pearl and upper closing in pipe, outward
The water in portion, air can not countercurrently enter the pump housing, thus the liquid only in liquid container can through suction pipe,
Wash lower reverse blocking pearl open, enter in the pump housing.During additionally, press elbow nozzle under, extraneous air can be from
Sealing and combine between lid lower end enter, enter in liquid container after passage, thus can realize
Liquid container internal and external pressure balance (if liquid container only goes out liquid and without air inlet, then cannot realize liquid smoothly
The extrusion of body).And when elbow nozzle is released, piston rod resets, thus sealing can contact sealing again
In conjunction with lid lower end, thus ensure when not in use, liquid container inner air and outer air can not circulate, liquid also without
Method is revealed.Above-mentioned seal form is mainly by sealing and the sealing that contacts combining between lid lower end, also
Could alternatively be the seal form directly sealing passage by flared section, so, after pressing under piston rod, expand
Mouth section leaves passage, and air can enter in liquid container, and after reset, flared section seals passage,
Liquid container inner air and outer air can not circulate, and liquid also cannot be revealed.And the utility model can use and possess height
Toughness, the macromolecular material of fire-retardant feature are made, thus can possess high tenacity, good fire-retardant energy
Power, ensures longer service life, improves safety in utilization, also beneficially environmental protection.
