Abstract
The utility model relates to a fire extinguisher valve. The fire extinguisher valve comprises a valve body, a valve rod, a carrying handle, a pressing handle, a safety pin and a rubber chain, wherein the valve rod is arranged in a cavity of the valve body, the top of the valve rod emerges from the valve body, a sealing ring connected with the valve body in sealing mode is arranged in the middle of the valve rod, a sealing cap, a gasket, a sealing gasket connected with the conical surface of the valve body in sealing mode sleeve the lower end of the valve rod, the sealing gasket is an elastic cylindrical body, the outer corner of the top of the sealing gasket is set to be a conical face, and the taper degree of the conical face is larger than the taper degree of the conical surface on the valve body. According to the fire extinguisher valve, the outer corner of the top of the sealing gasket on the valve rod is set to be the conical face, the taper degree of the conical face is larger than the taper degree of the conical surface on the valve body, the corner of the sealing gasket gradually shrinks during the contact process, a contact surface large in contact area is formed, and therefore the sealing surface of the sealing gasket is fully and evenly contacted with the valve body, and sealing performance of the sealing gasket is stable and reliable.
Description
Technical field
The utility model relates to a kind of fire extinguisher, especially relates to a kind of extinguisher valve.
Background technology
Fire extinguisher for press handle type, between its valve rod and spool, by sealing gasket, form and be tightly connected, for example be called " extinguisher valve " (notification number: CN202418617U), it comprises aluminium valve body, valve rod assembly, pressure handle, safety plug, vertical tube socket and spring, described aluminium valve body is provided with first long way and second long way, described first long way and second long way connect, described valve rod assembly is located in first long way, aluminium valve body top is exposed in described valve rod assembly upper end, described valve rod assembly lower end is connected with described spring, described spring is located in vertical tube socket, described vertical tube socket is connected with aluminium valve body, described second long way is provided with nozzle, described aluminium valve body is provided with the 3rd long way, in described the 3rd long way, be provided with successively guard terminal sealing gasket, the insurance the top of a wall and relief spring, and by insurance cap sealed, described pressure handle is rotationally connected by rivet and aluminium valve body, described safety plug is located on pressure handle, described safety plug end is provided with plastic packaging.In the disclosure technology, the sealing gasket between valve rod and spool, its part that participates in sealing is bight, and this bight is right angle, and contact area is little, and yielding formation is stressed irregular, causes sealing unstable.
Summary of the invention
The utility model main purpose provides the reliable and stable a kind of extinguisher valve that is tightly connected between a kind of valve rod and valve body.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of extinguisher valve, comprise valve body, valve rod, carrying handle, pressure handle, safety plug, rubber chain, it is characterized in that: valve rod is located in the cavity of valve body, top is exposed to valve body and middle part is provided with the sealing ring being tightly connected with valve body formation; Valve rod lower end is arranged with sealing cap, pad, forms with the conical surface on valve body the sealing gasket being tightly connected; Sealing gasket is elastic columnar shape body, and its top external angle is set to the conical surface, and the tapering of this conical surface is greater than the tapering of the conical surface on valve body.
As preferably, described pressure handle is rotationally connected by rivet and valve body.
As preferably, rubber chain penetrates carrying handle, then safety plug is penetrated to rubber chain.
Sealing gasket top external angle on the utility model valve rod is set to the conical surface, the tapering of the conical surface is greater than the tapering of the conical surface on valve body, in contact process, the bight of sealing gasket is shunk gradually, form larger contact area, the sealing surface that makes sealing gasket and valve body more fully, contact more equably, make sealing more reliable and more stable.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is the A place enlarged drawings in accompanying drawing 1.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of extinguisher valve of the utility model, as shown in accompanying drawing 1, accompanying drawing 2, it comprises valve body 1, valve rod 2, carrying handle 9, pressure handle 10, safety plug 11, rubber chain 12, valve rod 2 is located in the cavity of valve body 1, and top is exposed to valve body 1 and middle part is provided with the sealing ring 3 being tightly connected with valve body 1 formation; Valve rod 2 lower ends are arranged with sealing cap 6, pad 7, form with the conical surface on valve body 1 sealing gasket 5 being tightly connected; Sealing gasket 5 is elastic columnar shape body, and its top external angle is set to the conical surface, and the tapering of this conical surface is greater than the tapering of the conical surface on valve body 1.
Pressure handle 10 is rotationally connected by rivet 8 and valve body 1.
Rubber chain 12 penetrates carrying handle 9, then safety plug 13 is penetrated to rubber chain 12.Safety plug 11 ends arrange plastic packaging or lead sealing.
Valve body 1 lower end arranges external screw thread, and external screw thread root arranges sealing ring 4.
During use, press pressure handle, band ovable valve stem assembly moves downward, and opens valve, and the operation of putting out a fire, decontrols pressure handle, and valve rod moves upward under the effect of spring force, valve-off; When needs make to spray fire extinguisher, first pull out plastic packaging, more described safety plug is extracted, the operation of putting out a fire.
