Technical field
The utility model relates to a kind of fire extinguisher, especially relates to a kind of extinguisher valve.
Background technique
Fire extinguisher is for be generally all provided with arming pin, such as " extinguisher valve " (notification number: CN202418617U) by name, it comprises aluminium valve body, valve rod assembly, pressure handle, arming pin, 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, guard terminal sealing gasket is provided with successively in described 3rd long way, 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 arming pin is located on pressure handle, described arming pin end is provided with plastic packaging.In the disclosure technology, the structure of carrying handle, for heavy duty, bearing capacity is large not; And the sealing gasket between valve rod and spool, its part participating in sealing is bight, and this bight is right angle, and area of contact is little, and yielding formation is stressed irregular, causes sealing unstable.
Summary of the invention
The utility model main purpose be to provide a kind of load-bearing comparatively large, seal stable a kind of extinguisher valve.
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, arming pin, vertical tube socket and spring, it is characterized in that: valve body is provided with the first path connected and the alternate path that can arrange nozzle; Valve rod, vertical tube socket are located in the first path; The top of the upper end of valve rod is exposed to valve body and middle part is provided with and forms with valve body the seal ring be tightly connected, the endoporus of vertical tube socket is up big and down small shoulder hole, the hypomere of this shoulder hole is tapped hole, and both ends of the spring is resisted against on the tapped hole sidewall of valve rod lower end and vertical tube socket respectively; Valve body is provided with groove, and the end of carrying handle is inserted in this groove.
As preferably, valve body is provided with third path, is provided with sealing plain cushion, retracting spring, insurance valve seat, relief spring seat in third path successively.
As preferably, pressure handle is rotationally connected by rivet and valve body.
As preferably, valve rod lower end is arranged with sealing plain cushion, sealed cap, pad; 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.Sealed cap end arranges groove; Sealing gasket is up big and down small hierarchic structure, and upper end external diameter is greater than sealed cap external diameter, and lower end is arranged in the groove of sealed cap.
Therefore, the utility model valve body is provided with groove, and the end of carrying handle is inserted in this groove, can improve bearing capacity; Sealing gasket top external angle on valve rod is set to the conical surface, and 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 area of contact, formed more fully evenly contact, 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 a kind of structural representations of insurance valve seat.
Accompanying drawing 3 is the A place enlarged views in accompanying drawing 1.
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 11, pressure handle 12, arming pin 13, vertical tube socket 9 and spring 8, and valve body 1 is provided with the first path connected and the alternate path that can arrange nozzle.Seal ring 4 is established in valve body 1 lower end.
Valve rod 2, vertical tube socket 9 are located in the first path; The top of the upper end of valve rod 2 is exposed to valve body 1 and middle part is provided with and forms with valve body 1 seal ring 3 be tightly connected, the endoporus of vertical tube socket 9 is up big and down small shoulder hole, the hypomere of this shoulder hole is tapped hole, and spring 8 two ends are resisted against on the tapped hole sidewall of valve rod 2 lower end and vertical tube socket 9 respectively; Valve body 1 is provided with third path, is provided with sealing plain cushion 15, retracting spring 16, insurance valve seat 17, relief spring seat 18 in third path successively.
Valve rod 2 lower end is arranged with sealing plain cushion 5, sealed cap 6, pad 7.Sealed cap 6 and valve body form and are sealed and matched.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.Sealed cap 6 end arranges groove; Sealing gasket 5 is up big and down small hierarchic structure, and upper end external diameter is greater than sealed cap 6 external diameter, and lower end is arranged in the groove of sealed cap 6.
