Abstract
The utility model relates to a pressure limiting valve for a liquid fuel burner, which comprises an upper cover (3), a lower cover (12), a rubber membrane (6), a motion lever (9), a rubber pad (11), a gas nozzle (10), a handle (15), etc. When the pressure in a fuel tank (14) exceeds the nominal pressure, the rubber pad (11) and the gas nozzle (10) generate an interstice, the fuel tank (14) is communicated with the atmosphere, and the pressure relief starts. In this way, under any working condition, the pressure in the fuel tank (14) can be ensured within the normal value. The manual handle (15) is pressed to quickly eliminate the negative pressure in the fuel tank (14).
Description
The utility model relates to a kind of pressure limiting valve that is used for liquid fuel range.
92212875.8), self-pressing type light a fire the automatically liquid fuel burner (kitchen range) (patent No. 91212962.X) and self-pressing type liquid fuel furnace (the kitchen range) (patent No.: 92212335.7) liquid fuel range of the automatic supply fuel of now the having authorized (patent No.:, because stove (kitchen range) tool does not have pressure limiting device, the pressure in the fuel tank changes with many factors vary such as burner hearth firepower size, burning time, environment temperatures.This stove (kitchen range) tool is in the working time, firepower shakiness, and after the fuel tank internal pressure rises to certain value, will have liquid to release in the burner hearth, and light contaminated environment then, heavy then cause fire.
The purpose of this utility model provides a kind of under any working condition, guarantee the liquid fuel tank internal pressure at rated value with interior pressure limiting valve.
The utility model is realized by the following technical solutions: this pressure limiting valve is made up of set screw (1), spring (2), loam cake (3), nut (4), screw (5), rubber membrane (6), gripper shoe (7), lower cover (12), air inlet pipe (13) etc.Be separated with rubber membrane (6) between loam cake (3) and the lower cover (12), and fastening with screw (5), form not connected B chamber and A chamber in the valve.The B chamber communicates with atmosphere, and the A chamber is communicated with fuel tank (14) top by air inlet pipe (13).Gripper shoe (7) fuses by carriage release lever (9), elastic tape (8), nut (4) with rubber membrane (6), carriage release lever (9) is provided with a connecting rod (16), and one handle (15) is housed on the connecting rod (16), lower cover is opened a hole on (12), if a gas is chewed (10), set screw (1) is spun on the loam cake (3), and spring (2) is placed between bullet joint screw (1) and the gripper shoe (7).Have a hole in carriage release lever (9) lower end, be provided with a blanket gas in the hole and chew the valve rubber of (10) (11); Perhaps on carriage release lever (9),, pacify a fork (17) along its diametric(al) perforate, fork (17) one ends are fixed on the lower cover (12) with pin (18), and can rotate around pin (18), the other end has a hole, is provided with a blanket gas in the hole and chews the valve rubber of (10) (11).
Owing to adopted above-mentioned technical solution, made the interior pressure of fuel tank (14) of liquid fuel range remain in the rated value, compared with the prior art, safe and reliable during work, stopped disaster hidden-trouble, stable fire can be eliminated the interior negative pressure of fuel tank (14) rapidly.
Description of drawings:
Fig. 1 is the utility model embodiment 1 main generalized section of looking
Fig. 2 is the utility model embodiment 2 main generalized sections of looking
Embodiment one:
As shown in Figure 1, be provided with not connected B chamber, A chamber in the pressure limiting valve.The B chamber communicates with atmosphere, and the A chamber is communicated with fuel tank (14) top by air inlet pipe (13).On lower cover (12), open a hole, if a gas is chewed (10), carriage release lever (9) lower end has a hole, be provided with a blanket gas in the hole and chew the valve rubber of (10) (11), when fuel tank (14) and A cavity pressure when rating number is following, the pressure that spring (2) acts on the rubber membrane (6) acts on pressure on the rubber membrane (6) greater than the A chamber, rubber membrane (6) drives carriage release lever (9) and moves down, valve rubber (11) is chewed (10) with gas and is fitted, the A chamber only is communicated with fuel tank, is in closed state.When fuel tank (14) and A cavity pressure surpass rated pressure, the pressure that this moment, the A chamber acted on the rubber membrane (6) acts on pressure on the rubber membrane (6) greater than spring (2), rubber membrane (6) drives carriage release lever (9) upwards, valve rubber (11) is chewed (10) with gas and is produced the gap, A chamber and fuel tank (14) are communicated with atmosphere, the beginning release.When A chamber and fuel tank (14) internal pressure drop in the rated pressure, spring (2) acts on pressure on the rubber membrane (6) greater than the pressure that acts in the A chamber on the rubber membrane (6), rubber membrane (6) drives carriage release lever (9) and moves down, valve rubber (11) is chewed (10) with gas and is fitted again, A chamber and fuel tank (14) are in closed state again, and release stops.So circulation makes A chamber and fuel tank (14) pressure limit in rated value.Rotation set screw (1) position changes spring (2) decrement, can select the interior rated pressure size of fuel tank (14).
Press lower handle (15), promote connecting rod (16), affect carriage release lever (9), make valve rubber (11) chew (10) with gas and separate, can eliminate the negative pressure in the fuel tank (14) rapidly.
Embodiment two:
Shown in the accompanying drawing 2, fork (17) is transverse in carriage release lever (9) hole, and an end is fixed on the lower cover (12) with pin (18), and fork (17) can be around pin (18) rotation, and the other end is opened a hole, establishes a blanket gas in the hole and chews the valve rubber of (10) (11).Variation carriage release lever (9) upper-lower position drives fork (17) swing, and realization valve rubber (11) is chewed (10) and separated and applying with gas.All the other are with embodiment 1.
Claims (3)
1, a kind of pressure limiting valve that is used for liquid fuel range, it comprises set screw (1), spring (2), loam cake (3), nut (4), screw (5), rubber membrane (6), gripper shoe (7), lower cover (12), air inlet pipe (13) etc., its principal character is:
