Abstract
The utility model discloses a pressure reducing valve on the ever-living fire apparatus of the middle-pressure stove, which is composed of a valve body (6), an airway (1), a press cover (2), a seal ring and a pressure reducing control which comprises a regulating press plate (4), springs (5), a top plate (8) and a pressure reducing unit (7) positioned on an air outlet, the pressure reducing valve is suitable for medium-pressure stoves with ever-living fire lighting system, the manufacture and the installation are both convenient, the cost is reduced, and the reliability is increased.
Description
The utility model relates to a kind of air pressure reducer, the gas pressure reducer on specifically a kind of medium pressure furnace tool.
Middle compression ignite steam stove tool on the domestic market occurs very not of a specified duration, existing medium pressure furnace tool, and the ever-burning flame of its igniting usefulness is not mostly established pressure-reducing valve.Liquefied gas nozzle from ever-burning flame under higher pressure sprays fast, has not only caused the waste of a large amount of gas, and because pressure height, gas combustion are insufficient, can generate many pernicious gases.What have on the external medium pressure furnace tool is provided with pressure-reducing valve, but general manufacturing cost is all higher, finds the pressure-reducing valve with the utility model structure similar at present as yet.
The purpose of this utility model provides a kind of pressure loading valve that is used on the medium pressure furnace tool, and the manufacturing of this valve and use are all very convenient, and have reduced cost, have increased reliability.
In order to achieve the above object, the utility model has adopted following scheme: pressure-reducing valve is made up of valve body, wireway, gland, sealing ring and depressed control device, depressed control device comprises the decompression part of regulating pressing plate, top board, spring and gas outlet, this decompression part can be a steel ball, also can be rubber stopper or other article.
Like this, the valve body and the body of heater of pressure-reducing valve are combined as a whole, and have both made things convenient for manufacturing, have reduced cost again, install also very simply, and have increased reliability.
Below in conjunction with accompanying drawing to this practical being described further.
Fig. 1 is the structure chart of two kinds of different embodiments of the utility model with Fig. 2.
Embodiment 1 sees Fig. 1, and wherein (1) is wireway, and (2) are gland, and (3) are sealing ring, and (4) for regulating pressing plate, (5) are spring, and (6) are valve body, and (7) are rubber stopper, and (8) are top board.
Wireway (1) passes gland (2), and the cavity of gas importing pressure-reducing valve, gland (2) is a threaded engagement with valve body (6), and pushes down sealing ring (3), prevents that gas is excessive.Valve pocket top is for regulating pressing plate (4), regulating between pressing plate and valve body wall is threaded engagement, regulate the pressing plate center groove is arranged, can transfer the position of adjusting pressing plate by screwdriver insertion groove inward turning when opening gland, pressing plate props up top board (8) by spring (5) down, between top board (8) and the valve body wall slight gap is arranged also.Top board for rubber stopper (7), is sealed the gas outlet down.
After liquefied gas imports valve pocket by wireway, from the gap of regulating pressing plate and valve body wall threaded engagement, enter the cavity at middle part, and then infiltrate the bottom through the slit of top board.Place, gas outlet, bottom envelope has rubber stopper, lifts slightly under the gas pressure effect, and gas enters blast pipe.Like this, through three decompressions, pressure can reduce hundreds of times to gas altogether.Regulate the pressure size as need, thereby the size that only needs rotation adjusting pressing plate to change slit between rubber stopper and gas outlet can realize.
Embodiment 2 sees Fig. 2, and wherein (1) is wireway, and (2) are gland, and (3) are sealing ring, and (4) for regulating pressing plate, (5) are spring, and (6) are valve body, and (7) are steel ball, and (8) are top board.
The structure of relief pressure valve of embodiment 2 and operation principle are basic the same with embodiment 1, and the difference part that is to reduce pressure is a steel ball, but not rubber stopper can reach same effect of easing stress like this.
Claims (6)
1. medium pressure furnace tool pressure-reducing valve, form by valve body (6), wireway (1), gland (2), sealing ring (3) and depressed control device, it is characterized in that depressed control device comprises the decompression part (7) of regulating pressing plate (4), spring (5), top board (8) and being positioned at the gas outlet.
2. pressure-reducing valve as claimed in claim 1, it is characterized in that regulating between pressing plate (4) and the valve body (6) is threaded engagement.
3. pressure-reducing valve as claimed in claim 1 or 2, it is characterized in that regulating pressing plate (4) center has a groove, when opening gland, can be with regulating in the blade insertion groove, pressing plate (4) is regulated in rotation, thereby adjusts pressure.
4. pressure-reducing valve as claimed in claim 1, the decompression part (7) that it is characterized in that the gas outlet is a rubber stopper.
5. pressure-reducing valve as claimed in claim 1, the decompression part (7) that it is characterized in that the gas outlet is a steel ball.
6. pressure-reducing valve as claimed in claim 1 is characterized in that having between described top board (8) and valve body (6) inwall slit to exist.
