Abstract
The utility model discloses a novel stainless-steel pressure reducer, comprising a stainless-steel valve body and a stainless-steel valve cap, wherein the valve cap is used for closing the valve body to form a valve-body inner cavity. A stainless-steel pressure regulating diaphragm is arranged in the valve-body inner cavity, one end of the pressure regulating diaphragm is connected with a pressure-reducing valve mechanism, and the other end of the pressure regulating diaphragm is butted with a regulating spring. A regulating rod is connected on the valve cap, one end of the regulating rod extends out the valve cap, and the other end of the regulating rod is connected with the regulating spring. The wall of the valve-body inner cavity and the pressure regulating diaphragm are in a hard sealing structure. In the utility model, the valve body and the pressure regulating diaphragm adopt stainless steel and realize the hard sealing structure, and therefore the sealing effect is good. The sealing structure is not easy to corrode and age, so as to prevent potential safety problems and accidents caused by the damage, leakage and the like of the pressure reducer.
Description
Technical field
The utility model relates to decompressor.
Background technique
Because the gas cylinder internal pressure is higher, and the required pressure of gas welding and gas cutting and use point is less, so need come the gas that is stored in the elevated pressures in the gas cylinder is reduced to low-pressure gas with decompressor, and should guarantee that required working pressure keeps steady state from start to finish.Original decompressor adopts brass as main raw material(s) mostly, and rubber material is adopted in voltage regulation diaphragm device and sealing, and is diversified in specifications with the parent connecting thread.Its major defect is that the use occasion restriction is more, particularly short and easily aging working life in the corrosive gas occasion, because voltage regulation diaphragm adopts the problem of rubber structure with regard to the corrosion resistance difference that should wear out, easily cause leakage with being threaded of parent is diversified in specifications, decompressor well damage, leakage etc. and cause potential safety hazard and accident.
The model utility content
Technical problem to be solved in the utility model just provides a kind of good sealing effect, the not perishable aging decompressor of sealing configuration.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: novel stainless steel decompressor, comprise stainless steel body and stainless steel valve gap, the valve gap closed valve forms body cavity, described body cavity is provided with the stainless steel voltage regulation diaphragm, voltage regulation diaphragm one end connects reducing valve mechanism, voltage regulation diaphragm the other end apical grafting Regulation spring, be connected with adjustable lever on the valve gap, adjustable lever one end stretches out valve gap, the adjustable lever the other end links to each other with Regulation spring, it is characterized in that: described body cavity wall and voltage regulation diaphragm are hard sealing structure.
As preferably, described adjustable lever end is provided with top board apical grafting Regulation spring.
Valve body and voltage regulation diaphragm all adopt stainless steel and have realized hard sealing structure in the utility model, thereby good sealing effect, and sealing configuration is not perishable aging, prevent decompressor damage, leakage etc. and cause potential safety hazard and accident.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, embodiment for the utility model decompressor, comprise valve body 1 and valve gap 2, the valve gap closed valve forms body cavity, and described body cavity is provided with voltage regulation diaphragm 4, voltage regulation diaphragm one end connects reducing valve mechanism 3, voltage regulation diaphragm the other end apical grafting Regulation spring 5 is connected with adjustable lever 7 on the valve gap, adjustable lever one end stretches out valve gap, the adjustable lever the other end links to each other with Regulation spring, and described body cavity wall and voltage regulation diaphragm are hard sealing structure.Wherein, described voltage regulation diaphragm adopts the 316L stainless steel, and described valve body and valve gap adopt stainless steel to make.Described adjustable lever end is provided with top board 6 apical grafting Regulation springs.
Working principle of the present utility model is: be divided into the two-stage decompression system, suction port and reducing valve are inter-agency to be first order depressurized system 13, reducing valve mechanism 3, voltage regulation diaphragm 4, Regulation spring 5 and adjustable lever 7 are formed second level depressurized system, after pressurized gas enter valve body from suction port 11, first order depressurized system 13 is reduced to medium pressure gas automatically with pressurized gas, reducing to pressure is 2MPa, sends into second level depressurized system then.In the second depressurized system, when screwing adjustable lever 7, by Regulation spring 5, voltage regulation diaphragm 4 and reducing valve mechanism 3, make the opening and closing in various degree of reducing valve do, with the decompression degree that is used for regulating the oxygen that first depressurized system sends into or stop air feed, decompressor is reduced to low-pressure gas with pressurized gas and is kept the pressure and the stability of flow of output gas constant, 12 outflows from the air outlet at last.
