Abstract
The utility model belongs to the technical field of the fire engineering, especially, an inclined plane compression fire extinguisher valve case, including the valve rod, the fixed surface of valve rod has seted up the seal groove, and the inner wall of seal groove is the annular shape, and O type sealing washer has been cup jointed to the inner wall of seal groove, and the one end threaded connection of valve rod has the base, and the surface of valve rod is provided with connects sealing mechanism. This inclined plane compression fire extinguisher valve case, through the side direction and the axial compression planar axial extrusion that set up 45 cone angles, seal ring can not turn up and break away from base and seal groove, it is good to have a sealing performance, avoid when promptly putting out a fire, because of the fire extinguisher inefficacy causes the characteristics of unnecessary property economic loss, and have simple structure, the equipment is convenient, the working property is good and the practicality is strong advantage, thereby solved current fire extinguisher valve case sealing member and sprayed and easily drop, lead to the problem that the complete machine fire extinguisher became invalid.
Description
Technical Field
The utility model relates to a fire engineering technical field especially relates to an inclined plane compression fire extinguisher valve case.
Background
The fire extinguisher is a portable fire extinguishing tool. Chemical substances are placed in the fire extinguisher for saving and extinguishing fire. The fire extinguisher is one of common fire-proof facilities, is stored in public places or places where fires may happen, different fire extinguishers of different types are filled with different components and are specially designed for different fires, and people need to pay attention to use the fire extinguisher so as to avoid adverse effects and life risks.
The valve core of the existing fire extinguisher valve has the defects that the fire extinguisher often has the defects of sealing piece rupture during high-temperature intermittent injection and leakage during low-temperature filling. At present, the valve rod assembly of the carbon dioxide fire extinguisher on the market has two structures, one structure is manufactured by a rubber coating process, and the other structure is manufactured by an axial extrusion process. The encapsulation process is that the base is placed in a mold cavity and injection molding of the sealing element is carried out. The sealing surface of the valve rod assembly manufactured by the encapsulation process is uneven and smooth, and the sealing element is not tightly bonded with the sealing element base, so that the sealing performance is influenced, the sealing element is ejected and falls off due to the loose bonding, and finally the failure of the fire extinguisher of the whole machine is caused, so that the valve core of the inclined plane compression type fire extinguisher valve is needed.
SUMMERY OF THE UTILITY MODEL
Based on current fire extinguisher valve case sealing member sprays and easily drops, leads to the technical problem of complete machine fire extinguisher inefficacy, the utility model provides an inclined plane compression fire extinguisher valve case.
The utility model provides a pair of inclined plane compression fire extinguisher valve case, including the valve rod, the fixed surface of valve rod has seted up the seal groove, the inner wall of seal groove is the annular shape, the inner wall of seal groove has cup jointed O type sealing washer, the one end threaded connection of valve rod has the base, the surface of valve rod is provided with connects sealing mechanism, it includes axial compression plane to connect sealing mechanism, axial compression plane has been seted up to the fixed surface of valve rod.
Preferably, the surface of the base is fixedly provided with a sealing groove, and the inner wall of the sealing groove is inserted with a sealing gasket.
Preferably, the inner wall of the sealing gasket is in sliding connection with the surface of the valve stem, which is provided with a 45 ° taper angle.
Preferably, the surface of the 45 ° cone angle is inserted into the inner wall of the sealing washer, and the surface of the axial compression plane is inserted into the surface of the sealing washer.
The utility model provides a beneficial effect does:
1. through the side direction that sets up 45 cone angles and the axial extrusion of axial compression plane, seal ring can not turn up and break away from base and seal groove, has that sealing performance is good, avoids when promptly putting out a fire, because of the fire extinguisher inefficacy causes the characteristics of unnecessary property economic loss, and has simple structure, equipment convenience, the working property is good and the practicality is strong advantage to solved current fire extinguisher valve case sealing member and sprayed and easily drop, leaded to the problem that the complete machine fire extinguisher became invalid.
