Abstract
The utility model discloses a large-flow reducing valve, which comprises an air inlet, an air outlet, an upper valve body, a lower valve body, a rubber film, an adjusting spring, an adjusting bolt and a lever component. The large-flow reducing valve is characterized in that a piston type copper spray nozzle is mounted at the air inlet and fixedly connected into the air inlet in a threaded manner, a steel ball is mounted at an air inlet end of the copper spray nozzle and in fit connection with the air inlet end of the copper spray nozzle, a control button is connected to the upper end of the steel ball and controls the steel ball to be capable of longitudinally moving, a positioning spring used for limiting transverse movement of the steel ball is further disposed at the front end of the steel ball, an air outlet end of the copper spray nozzle contacts with a valve pad, and the other end of the valve pad is connected with the lever component to form a linkage mechanism. The large-flow reducing valve adopts the piston type copper spray nozzle, is safer in closing pressure and air tightness and more stable in pressure, and is widely applied to reducing valve equipment.
Description
Technical field
The utility model relates to a kind of reducing valve body device, a kind of especially high-flow pressure reducing valve.
Background technique
Reduction valve is mounted in and connects angle valve and sebific duct on the cylinder for liquefied gas angle valve, play the important gas-fired equipment of the household gas apparatus that reduces delivery pressure and stable output pressure in supporting, at present, the structure of relief pressure valve that adopts on the market mainly is made up of parts such as suction port, air outlet, handwheel, bonnet, bottom flange, air inlet nozzle, spiracle, upper gas chamber, underpressure chamber, valve pad, lever, rubber film, spring, adjusting plug screws; Have the valve opening that leads to the underpressure chamber in the suction port, rely on pressurized gas to push valve pad open, pressurized gas enter the underpressure chamber from suction port, the height of gas pressure is depended in the folding of valve opening fully, because existing bottom flange cavity volume is little, gas directly passes through, when gas pressure is high, opening of valve opening is just big, and gas flow is big, gas pressure hour, gas flow is just little, the flow of the gas of supply air outlet is just unstable like this, causes combustion instability, causes the flame instability of burner, it is insufficient to burn to the end, the gas of low pressure overstocks in bottle, can not use, and causes waste.
Summary of the invention
In order to overcome the deficiency of existing function technology, the utility model provides that a kind of tightness is good, a kind of high-flow pressure reducing valve of pressure stability.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of high-flow pressure reducing valve, comprise suction port, air outlet, upper valve body, following valve body, rubber film, Regulation spring, adjusting bolt, lever assembly is characterized in that being positioned at air inlet parts piston type copper nozzle are installed, and the copper nozzle is fixed in the suction port by being threaded; The inlet end of copper nozzle is equipped with steel ball, and steel ball top is connected with the control knob of control steel ball energy longitudinally-moving, and the front end of steel ball is provided with and is used to limit the laterally movable retaining spring of steel ball; The outlet side of described copper nozzle contacts with valve pad, and the other end and the lever assembly of valve pad connect to form linkage mechanism; Described valve body down is circular-arc cavity; Described button is fixed on the suction port by being threaded.
The beneficial effects of the utility model are: the utility model adopts piston type copper nozzle, and closing pressure and tightness are safer, and pressure is more stable; The structural design of original creation has changed a difficult safety switch and the manometric difficult problem of installing of piston type valve body, uses safety and reliability; The big cavity body structure design of the following valve body reduction valve of original creation makes reduction valve have the super large load, and pressure is more stable; Be widely used in the reducing valve body appliance arrangement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 be the utility model embodiment structural representation.
Embodiment
With reference to Fig. 1, a kind of high-flow pressure reducing valve of the utility model embodiment, comprise suction port 1, air outlet 2, upper valve body 3, following valve body 4, rubber film 5, Regulation spring 6, adjusting bolt 7, lever assembly 8, it is characterized in that being positioned at suction port 1 part piston type copper nozzle 9 is installed, copper nozzle 9 is fixed in the suction port 1 by being threaded; The inlet end of copper nozzle 9 is equipped with steel ball 11 and is connected, and steel ball 11 upper ends are connected with the control knob 12 of control steel ball 11 energy longitudinally-movings, and the front end that is positioned at steel ball 11 also is provided with and is used to limit the laterally movable retaining springs 13 of steel ball 11; The outlet side of described copper nozzle 9 contacts with valve pad 10, and the other end of valve pad 10 and lever assembly 8 connect to form linkage mechanism.Described valve body 4 down is circular-arc cavity.Described button 12 is fixed on the suction port 1 by being threaded.
Working principle of the present utility model: reduction valve is mounted in and connects angle valve and sebific duct on the cylinder for liquefied gas angle valve, play the important gas-fired equipment of the household gas apparatus that reduces delivery pressure and stable output pressure in supporting, have simple in structure, pressure stability, in light weight, regulate advantages such as easy for installation.When the user closed the switch of combustion gas tool, along with the liquefied petroleum gas (LPG) that enters down valve body 4 underpressure chamber increases, its pressure raise, and was got in rubber film 5 tops of being pressed by Regulation spring 6, and the part air that is present in the upper gas chamber of upper valve body 3 is discharged valve body by spiracle.Like this, force the lever of lever assembly 8 to move up, the valve opening that utilizes leverage to make valve pad 10 stop up copper nozzle 9 is closed, and has cut off the path of liquefied petroleum gas (LPG) import, and the pressure of following valve body 4 reduction valve outlet just no longer rises.Behind the switch of opening the combustion gas tool, liquefied petroleum gas (LPG) is from flowing out in valve body 4 reduction valve down, pressure in the underpressure chamber is descended, rubber film 5 is recessed, drives lever assembly 8 levers and moves down, and outside air enters upper gas chamber from spiracle, make valve pad 10 in move, it is big that admission space becomes, and air inflow increases, and pressure raises.Always it is constant that adjustment process makes the pressure of underpressure chamber so continuously, promptly no matter suction pressure is higher or on the low side, outlet pressure is always stable, thereby up to the effect of step-down and voltage stabilizing.
The utility model adopts piston type copper nozzle 9, and closing pressure and tightness are safer, and pressure is more stable; The structural design of original creation has changed a difficult safety switch and the manometric difficult problem of installing of piston type valve body, uses safety and reliability; The big cavity body structure design in following valve body 4 underpressure chamber of original creation makes reduction valve have the super large load, and pressure is more stable; Be widely used in the reducing valve body appliance arrangement.
In conjunction with the accompanying drawings specific embodiment of the utility model has been carried out exemplary description above, obviously the invention is not restricted to this, the details of other not specified (NS) is also in protection scope of the present invention.
