Abstract
The utility model discloses a valve core for a fire extinguisher valve. The valve core comprises a valve core body, wherein the valve core body is arranged in a valve body, made of an aluminum alloy and comprises a valve rod and a valve ball; the valve ball is arranged at the lower end of the valve rod; one end, which deviates from the valve ball, of the valve rod is spherical; a groove is formed in the circumferential surface of the valve ball, and a leak-proof ring is matched with the valve ball through the groove; two through holes are formed in the circumferential surface of the valve rod and penetrate through the axis of the valve rod, the through holesare threaded holes, a threaded rod is matched in one through hole, a force application piece is arranged at one end of the threaded rod, the other end of the threaded rod is matched with a lock nut, and the two through holes are arranged in an upper-and-lower manner. According to the valve core, a fire extinguisher can be locked before and during usage, when the fire extinguisher is not used, the fire extinguisher can be prevented from spraying due to locking, and when the fire extinguisher is used, force applied by hands of a user can be reduced due to locking.
Description
Technical field
The utility model relates to the spool that a kind of extinguisher valve is used.
Background technique
Existing fire extinguisher, untapped time, conventionally need to be pinned by safety pin, in the time that needs use, then safety pin is extracted, although which can avoid fire extinguisher to open, but it cannot realize locking after fire extinguisher is opened, therefore after fire extinguisher is opened, user still needs to continue the application of force, causes larger pressure to user.
Summary of the invention
The technical problems to be solved in the utility model is to provide the spool that a kind of extinguisher valve is used, this device can carry out locking before fire extinguisher does not use and while use, in the time that fire extinguisher does not use, locking can be avoided fire extinguishing device jet, and locking can reduce people's the hand application of force in use.
For addressing the above problem, the utility model adopts following technological scheme:
The spool that a kind of extinguisher valve is used, comprise the spool body that the aluminum alloy that is arranged in valve body is made, described spool body comprises valve rod and valve ball, described valve ball is arranged on valve rod lower end, one end that described valve rod deviates from valve ball is spherical, on the circumferential surface of described valve ball, be provided with a groove, and there is leakage-proof ring by this groove fit, on the circumferential surface of described valve rod, offer through hole, this through hole is through valve rod axle center, described through hole is tapped hole, in this through hole, be combined with a threaded stem, threaded stem one end is provided with application of force sheet, the other end is combined with lock-nut, described through hole is provided with two, present, lower arrangement.
As preferred technological scheme, the upper and lower end face of described valve ball is conical surface, on the conical surface of the lower end of valve ball, is provided with draw-in groove.
As preferred technological scheme, the bottom surface of described groove is circular arc.
As preferred technological scheme, described leakage-proof ring is for having flexible rubber ring, and the cross section of described leakage-proof ring is circular.
The beneficial effects of the utility model are: in the time that fire extinguisher does not use, threaded stem can be fitted on valve rod in the tapped hole in below, after threaded stem fits into, spool is by the cavity volume sealing of fire extinguisher, in the time that fire extinguisher uses, threaded stem can be fitted on valve rod in the tapped hole in top, after threaded stem fits into, spool is in lower shifting state, and cavity volume is opened, fire extinguishing device jet, this device can reduce user's the hand application of force, reduce manipulation strength, and the structure of this device is comparatively simple, manufacture more for convenience, is applicable to promoting the use of.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
