Specific embodiment
The purpose of this utility model is to provide a kind of valve, the structure design of the valve can prevent that valve rod from arbitrarily being taken
Under event occur, eliminate safe hidden trouble.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
A kind of valve that the utility model embodiment provides, including valve body 1 and valve rod 2.
Wherein, contractile limiting device and its mounting groove are provided on one in valve body 1 and valve rod 2, on another
The limiting slot with limiting device cooperation is provided with, and limiting device can be unfolded valve body 1 and valve rod 2 to be limited with limiting slot cooperation
Position.
Compared with prior art, valve provided by the utility model, in use, limiting device can be in valve body 1 and valve rod 2
Cooperation installation process in shrink in 2 mounting groove of valve rod or expansion is in 1 mounting groove of valve body, when valve body 1 and valve rod 2 coordinate
After in place, limiting device is deployable or shrinks with limiting slot cooperation fixing to prevent valve rod 2 from valve body 1 departing from；By in valve body 1
Position limiting structure is set between valve rod 2, the valve rod 2 during normal use can be avoided arbitrarily to be removed, so as to avoid
Thus the risk of the Liquified gas leakage brought, eliminates safe hidden trouble, and improves the reliability of valve, meets the regulation of national standard.
Various structures can be used in limiting device, specifically, referring to Fig. 1, Fig. 1 is the valve that the utility model embodiment provides
The structure diagram of door, in the embodiment, limiting device is clamp spring 3, the clamp spring 3 using the C-shaped configuration with an opening, so as to
Can have the function of to shrink or expand, this C-shaped configuration is not limited to certainly, in practical application, as long as can possess contraction
And/or the function of expansion, it is corresponding, it is provided with that the mounting groove of above-mentioned clamp spring 3, /V are installed on valve rod 2
Slot is arranged at valve body 1, and clamp spring 3 protrudes from mounting groove and can be contracted in mounting groove in the initial state, it is of course also possible to will
Clamp spring 3 is installed on valve body 1, sets to install the mounting groove of clamp spring 3 on valve body 1, limiting slot is arranged at valve rod 2, is blocked
Spring 3 protrudes from mounting groove and can be expanded in mounting groove in the initial state.
Further optimize above-mentioned technical proposal, for ease of in the engagement process of valve rod 2 and valve body 1, clamp spring 3 can be voluntarily
It shrinks or expands in order to which valve rod 2 is installed in place, in the utility model embodiment, formed at least one end face of clamp spring 3
There is annular to be oriented to the conical surface, for example, when clamp spring 3 is installed on valve rod 2, when assembling, the annular guide cone should be made facing towards valve body 1
On entrance, in this way, when valve rod 2 is into fashionable, clamp spring 3 will be contracted in mounting groove under the promotion of valve body 1, when clamp spring 3 is installed
In valve body 1, in assembling, the annular guide cone should be made using valve rod 2 clamp spring 3 to be promoted to be expanded to facing towards the entrance of valve body 1
In the mounting groove of valve body 1, in order to the assembling of valve rod 2.
To better ensure that limit effect, in the utility model embodiment, as shown in Figure 1, being used for installation card on valve rod 2
One side wall surface of the mounting groove of spring 3 is circular cone, i.e., in figure underlying one in two side walls face, when valve rod 2 has
When being upwardly separated from the trend of valve body 1, which can promote clamp spring 3 to expand, it is ensured that it coordinates with limiting slot, so as to play
The effect that valve rod 2 is preferably avoided to depart from valve body 1.
Certain said structure can similarly apply the mounting groove on valve body 1, opposite with the mounting groove on valve rod 2,
The side wall surface of the formation circular cone of mounting groove on valve body 1 is underlying one in two side walls face.
In addition to the embodiment shown in Fig. 1, limiting device can also use other structures, for example, limiting device bag
Limited block is included, limited block is telescopically arranged in the mounting groove on 2 side wall of valve body 1 and/or valve rod, and limited block can be in bullet
Property return unit under the action of stretch out in outside mounting groove, it is above-mentioned flexible to pass through slip of the limited block in mounting groove or rotate real
Existing, further, if limited block uses the connection mode rotated to be installed in mounting groove, pivot center can be with the axis of valve rod 2
