Description
Technical field
This practicality relates to valve field, especially relates to a kind of anti-jamming spring loaded check valve.
Background technology
Check-valves is also known as check (non-return) valve, check valve or non-return valve, and it acts on the fluid media (medium) directed flow being to ensure that in pipeline
And will not flow backwards.The valve rod of existing spring loaded check valve and valve rod are cased with fit clearance, easy hydrops or entrance in valve stem sleeve
Air, causes check-valves not open.Additionally check-valves is when closed, if having water or air in valve stem sleeve, in valve stem sleeve
Portion forms negative pressure, makes the check-valves can not normal switching-off.
Summary of the invention
For overcoming above-mentioned deficiency, this utility model provides a kind of anti-jamming spring loaded check valve, it is possible in making valve stem sleeve
Hydrops or air discharge smoothly, will not to valve rod formed resistance.Check-valves opens and closes more smooth and easy, reduces maintenance cost
With, reduce repair density.
The technical solution adopted in the utility model is as follows:
A kind of anti-jamming spring loaded check valve, including valve body, top cover, check plate, valve rod and valve stem sleeve, described valve body is upper
The hollow structure of under shed, the under shed of valve body is water inlet, and body top opening part seals and is covered with top cover, and top cover has
The outlet of connection valve inner, the lower central of top cover is fixedly connected with valve stem sleeve, and valve stem sleeve is vertical hollow pipeline, valve rod
Being provided with valve rod in set, valve rod is slidably connected with valve stem sleeve, and the bottom of valve rod connects has check plate, check plate to be positioned at valve body
Portion, check plate and valve interior wall are in sealing contact and the diameter of check plate is less than the valve diameter on check plate top, outside valve stem sleeve
Portion is set with the upper contact of spring, spring one end and check plate, the other end and the lower contacts of top cover, and described top cover has
The pod apertures connected with valve stem sleeve.The effect of pod apertures is to the water in valve stem sleeve or air be discharged, making check-valves
Open and close more smooth and easy.
As preferably, described pod apertures is positioned at the center of top cover.
As preferably, a diameter of 8mm of described pod apertures.According to the needs in real work, the diameter of pod apertures open into
8mm can be good at realizing function of the present utility model, and the check-valves of the pod apertures of other diameters also falls into this practicality newly certainly
The protection domain of type.
As preferably, described check plate is circular sheet-like structures.
As preferably, described check plate outer cover is provided with rubber cushion.The outside sheathed rubber cushion of circular sheet-like structures, it is possible to increase only
Returning the sealing effectiveness of plate, when making check plate close, effect is more preferable.
As preferably, the spacing d < 1mm of described valve rod and described valve stem sleeve inwall.
As preferably, described outlet has two, and profile is crescent and symmetrical about top cap central.So arrange not only
Be conducive to the smooth discharge of current, and it is the most smooth that top cover can be made to take off from valve body.
As preferably, top cover is connected with valve body screw thread.So arranging to make top cover pull down from valve body smoothly.
Compared with prior art, the beneficial effects of the utility model are:
The pod apertures connected with valve stem sleeve by top cap central, hydrops or air in valve stem sleeve can quickly discharge,
So that check-valves opens and closes more smooth and easy, dismantle convenient, reduce maintenance cost, reduce repair density.
Accompanying drawing explanation
Fig. 1 is front section view of the present utility model；
Fig. 2 is top view of the present utility model.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is specifically described.
As depicted in figs. 1 and 2, a kind of anti-jamming spring loaded check valve, including top cover 1, valve body 2 and check plate 4, valve body 2
For the hollow structure of upper and lower opening, the lower openings of valve body 2 is water inlet 8, and the lower sides of valve body 2 caves inward.Described valve
End face outer and the outer, bottom surface of body 2 all have screw 10, for check-valves is arranged on desired location.
Having two outlets 9 on top cover 1, outlet 9 is crescent and about top cover 1 centrosymmetry, top cover 1 and valve body
The upper shed of 2 is tightly connected, and the present embodiment uses threaded, uses this connected mode, it is possible to make top cover 1 very convenient
Pull down from valve body 2, it is simple to clean and keep in repair.
Top cover 1 bottom is fixedly connected with valve stem sleeve 7, is provided with valve rod 3 in valve stem sleeve 7, and valve rod 3 slides even with valve stem sleeve 7
Connecing, the bottom of valve rod 3 is connected with the central upper portion of check plate 4, and check plate 4 is positioned at valve inner, and check plate 4 is tied for round sheet
Structure, and the outer cover of check plate 4 is provided with rubber cushion.Check plate 4 contacts with the inner wall sealing of valve body, and the diameter of check plate 4 is less than position
In the valve diameter on check plate 4 top, being so conducive to the smooth unlatching of check plate 4, the present embodiment uses and is positioned at non-return
The sidewall of plate 4 lower body 2 caves inward, and is positioned at the sidewall mode outwardly of the valve body 2 on check plate 4 top.
The outer cover of valve stem sleeve 7 is equipped with the lower contacts of spring 6, spring 6 one end and top cover 1, the other end and check plate 4
Upper contact.
The center of top cover 1 has the pod apertures 5 connected with valve stem sleeve 7.Pod apertures 5 can make the hydrops in valve stem sleeve 7 or
Person's gas is quickly discharged, thus ensures that valve rod 3 can raising and lowering smoothly, it is ensured that will not block in check-valves work process
Extremely.
In the present embodiment, pod apertures 5 is opened in the center of top cover 7, a diameter of 8mm of pod apertures 5, valve rod 3 and valve rod
The inwall of set 7 coordinates spacing d < 1mm.
Specific works process is as follows, and check-valves is arranged on desired location, and now check-valves is closed, and works as current
When water inlet 8 flows into, due to the effect of hydraulic pressure, check plate 4 is backed down, so that current enter valve body 2, flows from outlet 9
Go out.When the water flow stops, owing to hydraulic pressure is not enough, under the effect of spring 6, check plate 4 closes, thus stops current to flow backwards.When
When entering liquid or air in valve stem sleeve 7, owing to the existence of pod apertures 5, liquid or air can quickly be got rid of, it is ensured that
The normal work of check-valves.When check-valves needs repairing or cleans, only top cover 1 need to be screwed out in valve body 2, can be by valve
Bar 3, check plate 4 and spring 6 take out in valve body 1, thus keep in repair whole check-valves.If members damages simultaneously
Bad, also have only to removable parts assembly, structure is simpler, uses convenient.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic is at this
Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from this utility model structure
Under, it is also possible to making some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without impact
Implementation result of the present utility model and practical applicability.The protection domain that this application claims should be with the content of its claim
Being as the criterion, the detailed description of the invention in description etc. records the content that may be used for explaining claim.
