In gas equipment, front end inlet pressure fluctuation can influence the stability that gas was used, leads to the load of gas-cooker or oven inaccurate, influences the culinary art effect. The pressure stabilizing valve can stabilize the action of pressure. The common pressure stabilizing valve is in a connection state for a long time after being connected into the gas circuit for use, and pressure fuel gas is directly introduced into the pressure stabilizing valve, so that the service life of the pressure stabilizing valve is reduced, and the pressure stabilizing valve is damaged and then has a long-time gas leakage risk. In the prior art, the pressure-stabilizing valve is protected by blocking the pressure fuel gas outside the pressure-stabilizing valve through a structure with a cut-off function in the pressure-stabilizing valve. However, such a pressure stabilizing valve is complicated in structure and high in manufacturing cost.

In view of the above problems, referring to fig. 1, a pressure stabilizing valve 100 according to an embodiment of the present application includes: a main body 110, a base plate 120, a shut-off assembly 130, and a voltage stabilizing assembly 140.

Specifically, the shutoff component 130 may shut off the pressure stabilizing valve 100 from the air supply line, avoiding the pressure stabilizing valve 100 from being in a pressure environment for a long period of time; the pressure stabilizing component 140 can adjust the pressure of the gas output by the pressure stabilizing valve 100, so that the pressure stabilizing valve 100 outputs the gas with stable pressure. Referring to fig. 3, the main body 110 has an air inlet 111, a first chamber 112, a second chamber 113, a third chamber 114, and an air outlet 115, which are sequentially communicated, the air inlet 111 is connected to an air supply line, and the air outlet 115 is connected to an air using device. In the case of using gas, the gas flows in the surge valve 100 and passes through the gas inlet 111, the first chamber 112, the second chamber 113, the third chamber 114, and the gas outlet 115 in this order.

When the relative position of the positioning member 144 and the inner wall of the through hole is adjusted, the pressing member 145 moves along with the positioning member 144 in the up-down direction (as shown in fig. 4), and the other end of the pressing member 145 drives the adjusting core 141 to move relative to the connecting port, so as to adjust the corresponding part of the adjusting core 141 to be placed in the connecting port and change the ventilation area of the connecting port. In this way, the opening degree of the connection port can be adjusted by adjusting the positioning member 144 to adjust the gas pressure of the gas outlet 115. In some embodiments, the compression member 145 may be an elastic member.

The regulator valve 100 outputs a gas of a certain pressure through the positioning member 144 and the regulating core 141. When the pressure of the gas inputted into the pressure stabilizing valve 100 fluctuates, the pressure loss of the gas is changed by adjusting the diaphragm 142 and the pressing member 145, thereby stabilizing the gas pressure. For example, when the gas pressure in the regulator valve 100 increases, the gas flowing through the third chamber 114 pushes the regulating diaphragm 142 upward (in the direction shown in fig. 4), the regulating block 1411 moves upward (in the direction shown in fig. 4), the ventilation area of the connection port decreases, and the packing 145 is compressed, causing a loss of gas pressure, so that the gas pressure output from the regulator valve 100 remains stable.

Referring to fig. 4, according to some embodiments of the present application, a support plate 1421 is disposed on a side of the adjusting diaphragm 142 facing the pressing cover 143, the adjusting core 141 is disposed through the adjusting diaphragm 142 and connected to the support plate 1421, and the pressing member 145 abuts against the support plate 1421 to protect the adjusting diaphragm 142. The support plate 1421 may be disposed at a central position of the adjusting diaphragm 142, one end of the adjusting core 141 is disposed through the adjusting diaphragm 142 and the support plate 1421, and the adjusting core 141 is fixedly connected to the support plate 1421, for example, the adjusting core 141 and the support plate 1421 may be connected through threads. One end of the pressing member 145 is connected to the positioning member 144, and the other end of the pressing member 145 abuts against the support plate 1421. The pressing member 145 and the adjusting core 141 are connected with the adjusting diaphragm 142 through the supporting plate 1421, so that the stress area of the adjusting diaphragm 142 can be increased, and the damage to the adjusting diaphragm 142 due to concentrated stress can be avoided.

The gas cooker according to the embodiment of the application includes the pressure stabilizing valve 100 as described above. The pressure stabilizing valve 100 is connected between the gas supply line of the gas cooker and the gas consuming device. When using the gas, the pressure stabilizing valve 100 outputs the gas with stable pressure to the gas using device, and the load of the gas stove is kept stable, so as to improve the cooking effect. When the gas is not used, the cut-off component 130 of the pressure stabilizing valve 100 can block the gas at the gas inlet 111 of the pressure stabilizing valve 100, so that the pressure stabilizing valve 100 is prevented from being in a pressure environment for a long time, the service life of the pressure stabilizing valve 100 is prolonged, and the use safety of the gas stove is improved.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
