Description
Technical field
The utility model relates to a kind of gas-fired equipment, especially a kind of combustion gas pressure maintaining valve, specifically a kind of pressure maintaining valve of energy quick adjustment delivery pressure.
Background technique
As everyone knows, pressure maintaining valve is to guarantee combustion stablized basis, it can adjust the size of atmospheric pressure automatically according to incoming pressure, make delivery pressure constant in certain scope, adjust the size of atmospheric pressure if desired, the decrement that only need regulate pressure adjusting spring can realize the adjusting of output pressure size.In the double-source gas system, because described air pressure differed bigger when different sources of the gas burnt, air pressure as natural gas needs between the 4-7 inches of water, the air pressure of liquid gas needs between the 8-11 inches of water, therefore, must regulate pressure adjusting spring when changing source of the gas, and the look nut that existing pressure maintaining valve all needs to be fitted on the pressure adjusting spring by rotation carries out the adjustment of pressure, not only adjustment cycle is long, and be difficult to reach the optimum state, it is very important to the usability that improves gas-fired equipment therefore to design a kind of pressure maintaining valve to the quick adjustment delivery pressure.
Summary of the invention
The purpose of this utility model is long with the pressure maintaining valve pressure regulation time at existing combustion gas, and is difficult to grasp the problem of whether adjusting to the right place, designs a kind of pressure maintaining valve that presses the energy quick adjustment delivery pressure that promptly switches to the required air pressure of corresponding source of the gas.
The technical solution of the utility model is:
A kind of pressure maintaining valve of energy quick adjustment delivery pressure, comprise valve body 1, valve body 1 is provided with gas-entered passageway 2 and outlet passageway 3, gas-entered passageway 2 is provided with the air outlet 4 that communicates with outlet passageway 3, seal ring 14 and pressure regulation bolt 5 are installed in air outlet 4, seal ring 14 is inlaid in the air outlet 4, pressure regulation bolt 5 is movably arranged in the air outlet 4, the lower end of pressure regulation bolt 5 is arranged in gas-entered passageway 2, the upper end of pressure regulation bolt 5 links to each other with epithelium 6, epithelium 6 is divided into one with outlet passageway 3 and is used for combustion gas air chamber by combustion gas and one and stops up greater than the atmosphere gas that communicates, on epithelium 6 one side relative pressure adjusting spring 7 is installed with the atmosphere air chamber, the upper end of pressure adjusting spring 7 is arranged in pilot hole 8, the upper end that it is characterized in that described pressure adjusting spring 7 offsets by connecting rod 9 and sphenoid surface bottom slide block 10, sphenoid surface bottom slide block 10 offsets with the sphenoid surface top slide block 11 that matches, and button 12 is housed in sphenoid surface top slide block 11, in the bottom of sphenoid surface bottom slide block 10 Returnning spring 13 is installed.
The beneficial effects of the utility model:
The utility model is by calculating the well decrement of the pressure adjusting spring of the atmospheric pressure value correspondence of different sources of the gas in advance, utilize the principle of the shrinkable ball point pen of existing pen core, make by depressing top slide block that bottom slide block is descending to be pressed on the pressure adjusting spring, thereby make delivery pressure increase to the state of liquid gas fast, pushing top slide block again, again bottom slide block to be resetted up, make pressure adjusting spring return to the rock gas state, it is quick, accurate that pressure is regulated, and uses very convenient.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of pressure maintaining valve of energy quick adjustment delivery pressure, comprise valve body 1, valve body 1 is provided with gas-entered passageway 2 and outlet passageway 3, gas-entered passageway 2 is provided with the air outlet 4 that communicates with outlet passageway 3, seal ring 14 and pressure regulation bolt 5 are installed in air outlet 4, seal ring 14 is inlaid in the air outlet 4, pressure regulation bolt 5 is movably arranged in the air outlet 4, the lower end of pressure regulation bolt 5 is arranged in gas-entered passageway 2, the upper end of pressure regulation bolt 5 links to each other with epithelium 6, epithelium 6 is divided into one with outlet passageway 3 and is used for combustion gas air chamber by combustion gas and one and stops up greater than the atmosphere gas that communicates, on epithelium 6 one side relative pressure adjusting spring 7 is installed with the atmosphere air chamber, the upper end of pressure adjusting spring 7 is arranged in pilot hole 8, the upper end of pressure adjusting spring 7 offsets by connecting rod 9 and sphenoid surface bottom slide block 10, sphenoid surface bottom slide block 10 offsets with the sphenoid surface top slide block 11 that matches, and button 12 is housed in sphenoid surface top slide block 11, in the bottom of sphenoid surface bottom slide block 10 Returnning spring 13 is installed.As shown in Figure 1.
Under the normal condition, the pressure that pressure produced that pressure adjusting spring 13 is applied on the epithelium 6 is waited until mutually with the air pressure of air outlet, if air pressure is excessive, then can lift epithelium 6, drive and to move on the pressure regulation bolt and overlap with seal ring 14 air outlet 4 is blocked, thereby the air pressure of air outlet is descended, and pressure adjusting spring 7 presses down, and drives pressure regulation bolt 5 and leaves seal ring 14, open the air outlet, like this repeatedly so that the pressure in the outlet passageway 3 is kept a constant level, in the case, if wish to adjust the atmospheric pressure that of outlet passageway 3, then can adjust the decrement of pressure adjusting spring, increase decrement, the pressure in the outlet passageway 3 increases, otherwise then diminishes.
In the dual gas supply system because different sources of the gas required air pressure difference of when burning, therefore need the amount of regulating also bigger, if there is not quick controlling device, then need to regulate repeatedly the decrement of pressure adjusting spring, not only the time long, and regulated quantity is difficult to grasp.And adopt the structure that has the slide block up and down of sphenoid surface of the present utility model, only need press button and get final product quick adjustment, and this compression is to determine by calculating in advance to the desired position.Whole adjustment state and process are shown in Fig. 2-7.The working principle of slide block is similar to the working principle of existing ball point pen up and down.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
