Less than the opening diameter of each self-corresponding limitting casing body, connected by metal bracelet between two metal balls；
The bottom of valve body is provided with intake tunnel, the base diameter of valve rod is identical with the diameter of intake tunnel；And,
When valve rod is not rotated up, the bottom of valve rod contacts to form sealing with the inwall of intake tunnel, and blocking water inlet is logical
The connection in road and exhalant canal；
When valve rod is rotated up, space is formed between valve rod and intake tunnel, connect intake tunnel and exhalant canal.
Furthermore it is preferred that structure be, the port that the exhalant canal is in communication with the outside be delivery port, on delivery port set
There is protective cover.
Additionally, it is preferred that structure be to be pasted with seal washer in the position of the bottom of valve rod and intake tunnel joint.
Compared with prior art, the utility model has the advantage of：
A spacing framework is respectively fixedly connected with exhalant canal on the valve rod, placed respectively in two limitting casing bodies
One metal ball that can only be moved in limitting casing body, two metal balls are connected by metal bracelet, make the valve rod cannot be by hydraulic pressure
Go out valve body.
Brief description of the drawings
By reference to the explanation below in conjunction with accompanying drawing and the content of claims, and with to it is of the present utility model more
Comprehensive understanding, other purposes of the present utility model and result will be more apparent and should be readily appreciated that.In the accompanying drawings：
Fig. 1 is the overall structure diagram of the above ground hydrant according to the utility model embodiment.
Reference therein includes：Bonnet 1, valve rod 2, valve body 3, exhalant canal 31, intake tunnel 32, spacing framework 4,
Metal ball 5, metal bracelet 6, protective cover 7.
Identical label indicates similar or corresponding feature or function in all of the figs.
Specific embodiment
Specific embodiment of the utility model is described in detail below with reference to accompanying drawing.
Fig. 1 shows the structure of the above ground hydrant according to the utility model embodiment.
As shown in figure 1, the above ground hydrant that the utility model is provided, including：Bonnet 1, valve rod 2 and valve body 3, valve rod 2 set
Put in the inside of valve body 1, and extended valve body 3 top, be provided with through hole on the inwall at the top of valve body 3, set on through hole
Internal thread is equipped with, the external screw thread with screw-internal thread fit is provided with valve rod 2, the top of valve rod 2 connects through through hole with bonnet 1
Connect, when rotary valve cover 1, rotating upwardly and downwardly for valve rod 2 is realized with externally threaded cooperation by internal thread.
Exhalant canal 31 is respectively arranged with the both sides of valve body 3, being not provided with externally threaded position in valve rod 2 is fixedly connected with
Spacing framework 4, is also fixedly connected with spacing framework 4 on the inwall of valve body 3, is fixed on the spacing framework 4 on the inwall of valve body 3
Can be fixed on the inwall of exhalant canal 31, a metal ball 5 is respectively put into each spacing framework 4, it is spacing at each
There is an opening respectively, the opening diameter of each spacing framework 4 is respectively less than the metal ball 5 in respective spacing framework 4 in framework 4
Diameter, to prevent metal ball 5 from moving out spacing framework 4, connected by metal bracelet 6 between two metal balls 5, spacing framework
4th, metal ball 5 and metal bracelet 6 constitute a stopping means, the up and down motion for limiting valve rod 2.
The bottom of valve body 3 is provided with intake tunnel 32, when valve rod 2 is rotated up, the limitting casing on valve rod 2 is fixed on
Metal ball 5 in body 4 and spacing framework 4 is rotated up therewith, and the spacing framework 4 being fixed on the inwall of valve body 3 is remained not
It is dynamic, because the metal ball 5 in two spacing frameworks 4 is ined succession by metal bracelet 6, so as to limit the upward motion of valve rod 2, prevent
Valve rod 2 goes out valve body 3 by the hydraulic pressure of intake tunnel 32.
Preferably, externally threaded position is not provided with valve rod 2 and offers a circle groove, spacing framework 4 connects with valve rod 2
Tactile position is set to the shape being adapted with groove, can be slided in groove, spacing so as to when valve rod 2 is rotated up
Framework 4 need not concomitant rotation, and moved along a straight line relative to the spacing framework 4 being fixed in exhalant canal 31.
The base diameter of valve rod 2 is identical with the diameter of intake tunnel 32, to realize sealing function.Specifically, in valve rod 2 not
When being rotated up, the bottom of valve rod 2 contacts to form sealing with the inwall of intake tunnel 32, blocks intake tunnel 32 and exhalant canal
31 connection；When valve rod 2 is rotated up, space is formed between valve rod 2 and intake tunnel 32, intake tunnel 32 is led to water outlet
Road 31 is connected.
In a preferred embodiment of the present utility model, the port that exhalant canal 31 is in communication with the outside is delivery port,
Protective cover 7 is provided with delivery port.
In order to ensure the sealing between valve rod 2 and intake tunnel 32, in another side of being preferable to carry out of the present utility model
Formula collects, and seal washer (not shown) is pasted with the position of the bottom of valve rod 2 and the joint of intake tunnel 32.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be described with power
The protection domain that profit is required is defined.
