Abstract
The invention relates to the technical field of high pressure pump manufacture and in particular relates to a screw-installed liquid inlet valve combination which is characterized by comprising a liquid inlet valve plate positioning sleeve and a liquid inlet valve plate, wherein the liquid inlet valve plate is sleeved on the liquid inlet valve plate positioning sleeve, a spring is arranged between the liquid inlet valve plate positioning sleeve and the liquid inlet valve plate and a thread is formed in one end of the liquid inlet valve plate positioning sleeve. The screw-installed liquid inlet valve combination is simple in structure and has excellent guide, limiting and reset functions; the liquid inlet valve plate sleeves the liquid inlet valve plate positioning sleeve, when being installed, only the liquid inlet valve plate positioning sleeve needs to be screwed on a high pressure pump through the thread, thus the combination and installation are facilitated and the integrity is good.
Description
Technical field
The present invention relates to high-pressure service pump manufacturing technology field, relate in particular to a kind of spiral shell dress type liquid feed valve combination.
Background technique
The pump that plunger pump manufacturer produces both at home and abroad, the liquid feed valve of employing and liquid discharging valve, be all not have the dynamic passive entire valve of opening substantially.Start when plunger stretches out working stroke, the thrust of plunger makes liquid produce pressure, and liquid discharging valve is opened, and liquid feed valve closes entire under the effect of spring force simultaneously; Plunger continues to move ahead according to curve speedup and deceleration, and liquid discharging valve is opened manyly because flow velocity increases under the impact of working fluid, and flow velocity reduces and opens gradually little valve and open, and liquid discharging valve closes entire under the effect of spring force simultaneously; Plunger continues retraction, and liquid feed valve reaches and starts afterwards farthest to retract at liquid fluidization tower plug, and feed liquor stroke starts, and the fluid pressure in feed pathway makes to open under feed liquor impact gradually large---and gradually little.Comparatively complicated for the liquid feed valve structure on high-pressure service pump in prior art, more loaded down with trivial details when installation, be difficult for installation and removal maintenance.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of spiral shell dress type liquid feed valve combination is provided, be convenient to install, sealing is strong.
The present invention for achieving the above object, by the following technical solutions: a kind of spiral shell dress type liquid feed valve combination, it is characterized in that: comprise feed liquor valve plate setting sleeve and feed liquor valve plate, described liquid feed valve sleeve-board is contained on described feed liquor valve plate setting sleeve, between described feed liquor valve plate setting sleeve and described feed liquor valve plate, be provided with spring, described feed liquor valve plate setting sleeve one end is provided with screw thread.
Preferably, described feed liquor valve plate setting sleeve is made up of cylindrical portion and opening portion, and the cross section of described opening portion is trapezoidal, and one end of opening portion minimum diameter is connected with described cylindrical portion, and described screw thread is arranged in cylindrical portion.
Preferably, described opening portion outer end ring week be provided with annular projection, the cross section of described feed liquor valve plate is L-shaped, the outer ring of described liquid feed valve setting sleeve is provided with ladder platform, described feed liquor valve plate coordinates with described ladder platform, and described spring is arranged between described annular projection and the long limit of feed liquor valve plate.
The invention has the beneficial effects as follows: the present invention is simple in structure to there is good guiding, spacing, reset function, liquid feed valve sleeve-board is contained on feed liquor valve plate setting sleeve, when mounted, only feed liquor valve plate setting sleeve need to be screwed on high-pressure service pump by screw thread, be convenient to combination and install, good integrity.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment, as shown in Figure 1, the combination of a kind of spiral shell dress type liquid feed valve, comprise feed liquor valve plate setting sleeve 1 and feed liquor valve plate 2, described liquid feed valve sleeve-board is contained on described feed liquor valve plate setting sleeve, between described feed liquor valve plate setting sleeve and described feed liquor valve plate, be provided with spring 3, described feed liquor valve plate setting sleeve one end is provided with screw thread 4.Feed liquor valve plate can carry out shutoff by liquid entering hole under the effect of spring, when mounted, feed liquor valve plate setting sleeve is together arranged on to the liquid feeding end of water pump by screw thread together with feed liquor valve plate, and it is convenient to install.
Enter for the ease of current, described feed liquor valve plate setting sleeve is made up of cylindrical portion 5 and opening portion 6, and the cross section of described opening portion is trapezoidal, and one end of opening portion minimum diameter is connected with described cylindrical portion, and described screw thread is arranged in cylindrical portion.
In order to make feed liquor valve plate slide on feed liquor valve plate setting sleeve smoothly, described opening portion outer end ring week be provided with annular projection 7, the cross section of described feed liquor valve plate is L-shaped, the outer ring of described liquid feed valve setting sleeve is provided with ladder platform 8, described feed liquor valve plate coordinates with described ladder platform, and described spring is arranged between described annular projection and the long limit of feed liquor valve plate.
The present invention is simple in structure, has good guiding, spacing, reset function, and liquid feed valve sleeve-board is contained on feed liquor valve plate setting sleeve, when mounted, only feed liquor valve plate setting sleeve need to be screwed on high-pressure service pump by screw thread, is convenient to combination and installs, good integrity.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
