Description
Technical field
The utility model is related to a kind of check-valves, specifically a kind of novel horizontal check-valves.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.Check-valves is divided into Vertical Lift Check Valves and sleeping by its structure
Formula check-valves, as its name suggests, horizontal check valve are exactly a kind of check-valves that valve pocket uses level connection joint mode.It is CN in notification number
In a kind of 204387412 U non-return valve, by setting three valve shafts being connected with valve plate, and three valve shafts are triangular in shape
Distribution, utilizes the stability of triangle to improve intensity of the valve plate when opening and closing, it is to avoid because long-time using rear valve plate position occurs
The phenomenon of skew, because when medium ends, valve plate is moved downward under its own Action of Gravity Field closes valve port, and intake antrum
Interior total hydraulic pressure that there is the system that must be from, causes valve plate closing velocity slow, always has certain media backflow, thus response speed
Degree is slow, in addition, in above-mentioned file valve body can only right angle setting, otherwise valve plate can not move under its Action of Gravity Field, and actually
In, the setting angle of check-valves is various, therefore the check-valves application place in above-mentioned file is limited, it is necessary to enter to it
Row is improved.
Utility model content
The purpose of this utility model is to provide a kind of novel horizontal check-valves, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：
A kind of novel horizontal check-valves, including：Valve body, valve plate, valve rod, valve stem sleeve, platen, valve shaft and bonnet, it is described
Valve rod is arranged in valve stem sleeve and can slided in valve stem sleeve, and stem bottom is fixedly connected with valve plate, and the valve rod is total to valve stem sleeve
There are three groups, and three groups of valve rods and valve stem sleeve distribution triangular in shape；It is fixedly connected at the top of valve stem sleeve below platen, the platen is
Valve shaft is fixedly connected with the top of cylindrical disk body, platen, the bonnet is arranged on above valve body by bolt, spiral shell in setting in bonnet
Line, and external screw thread is set on valve shaft excircle, valve shaft is arranged in bonnet by the helicitic texture, in addition, valve rod and valve stem sleeve
It is respectively provided with stage clip outside.
It is used as further program of the utility model：The valve plate is round table-like, sets in valve seat, valve seat and sets in valve body
The annular slope being engaged with round platform excircle.
It is used as further program of the utility model：It is provided with the excircle of the valve plate in annular groove, the annular groove
O-ring is set.
It is used as further program of the utility model：Rubber washer is set between the bonnet and valve body.
Compared with prior art, the beneficial effects of the utility model are：The utility model is improved to prior art, is led to
Cross and stage clip be set outside valve rod and valve stem sleeve, the driving force closed by the elastic force of stage clip as valve plate, with fast response time,
The advantage such as timely is closed, is not also influenceed by the setting angle of valve body, in addition, the valve shaft installed by screw thread is acted on, be can adjust
The pretightning force that valve plate is opened, so as to change the Opening pressure of valve plate, application scenario will be more extensive.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the mplifying structure schematic diagram at A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~2, the utility model embodiment, a kind of novel horizontal check-valves, including：Valve body 1, valve plate 2,
Valve rod 41, valve stem sleeve 42, platen 6, valve shaft 9 and bonnet 8, the valve rod 41 are arranged in valve stem sleeve 42 and can be in valve stem sleeves 42
Interior to slide, the bottom of valve rod 41 is fixedly connected with valve plate 2, and the valve rod 41 has three groups, and three groups of valve rods 41 and valve with valve stem sleeve 42
The distribution triangular in shape of rod set 42；The top of valve stem sleeve 42 is fixedly connected on the lower section of platen 6, and the platen 6 is cylindrical disk body, platen
6 tops are fixedly connected with valve shaft 9, and the bonnet 8 is arranged in the top of valve body 1, bonnet 8 by bolt and sets internal thread, and valve shaft 9
External screw thread is set, and valve shaft 9 is arranged in bonnet 8 by the helicitic texture, in addition, valve rod 41 is outer with valve stem sleeve 42 on excircle
Stage clip 5 is set, upward reasoning is produced to valve plate 2 when media flow, valve plate 2 moves up and compresses stage clip 6, in medium
During stopping, the elastic force of stage clip 6 makes the closing rapidly of valve plate 2, no longer only relies on valve as the restoring force for moving down valve plate 2
The gravity closure of plate 2 itself, response speed is substantially accelerated, when valve plate 2 is closed, and rotates valve shaft 9, effect of the platen 6 in valve shaft 9
Lower (or upward) downwards is mobile, is compressed stage clip 5, so as to improve the Opening pressure of (or reduction) valve plate 2, realizes that valve plate 2 is opened
Open the regulation of pressure.
