Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The utility model relates to a valve capable of adjusting large and small fires simultaneously, which comprises a valve seat 100 and a valve core 200.

As shown in fig. 1 and 2, the valve seat 100 is provided with an inlet duct 110, an inner ring flame duct 120, and an outer ring flame duct 130, and the valve body 200 is rotatably installed in the installation hole 140 of the valve seat 100. One end of each of the air inlet passage 110, the inner ring fire air passage 120 and the outer ring fire air passage 130 is connected to the mounting hole 140, and the other end is an air inlet end, an inner ring fire air outlet end and an outer ring fire air outlet end. As shown in fig. 3 and 4, the valve element 200 is in a cylindrical shape, and a first air groove 210, a second air groove 220, and a communication groove 230 are formed on an outer side wall of a curved surface of the valve element 200. Taking the direction in which the axial direction of the valve element 200 is vertically disposed in the space as an example, the first air groove 210 and the second air groove 220 are distributed up and down on the valve element 200. The first air groove 210 and the second air groove 220 surround the central axis of the valve core 200, and are opened along the circumferential direction of the outer wall of the valve core 200. The communication groove 230 connects the first air groove 210 and the second air groove 220. In this embodiment, the upper end of the communication groove 230 is connected to the right end of the first air groove 210, and the lower end of the communication groove 230 is connected to the left end of the second air groove 220. Preferably, the communication groove 230 is parallel to the central axis of the valve core 200 and is opened along the axial direction, that is, the right end of the first air groove 210 is located right above the left end of the second air groove 220. When the valve core 200 is mounted on the valve seat 100, one end of the inlet duct 110 close to the valve core 200 is at the same height in space with the second air groove 220; one end of the outer fire air passage 130 close to the valve core 200 is at the same height with the first air groove 210 in terms of space; the transfer position 201 of the first air groove 210 and the communication groove 230 (i.e., the left end of the first air groove 210 and the lower end of the communication groove 230 in this embodiment) is spatially at the same height as the end of the inner ring flame path 120 close to the valve element 200.

In practical use, when the valve is in a closed state, the second air groove 220 and one end of the air inlet channel 110 may be always kept in a mutually communicated state with opposite positions, or the right end of the second air groove 220 and one end of the air inlet channel 110 may be dislocated. At this time, the first air groove 210, the port of the outer ring fire air passage 130 and the port of the transition position 201 in the inner ring fire air passage 120 are in a staggered state, that is, the gas in the inlet passage 110 cannot be transmitted to the inner ring fire air passage 120 and the outer ring fire air passage 130 through the valve core 200. In the embodiment, the valve core 200 rotates around the central axis in the counterclockwise direction as the valve opening direction, the second air groove 220 is aligned to the port of the air inlet passage 110, the second air groove 220 is communicated with the port of the air inlet passage 110, the left end of the first air groove 210 is gradually overlapped and communicated with the port of the outer ring fire air passage 130, synchronously, the switching position 201 is gradually overlapped and communicated with the port of the inner ring fire air passage 120, at the moment, the fuel gas is conveyed to the inner ring fire air passage 120 through the air inlet passage 110, the second air groove 220 and the switching position 201, and a part of the fuel gas flows through the switching position 201, the communication groove 230 and the first air groove 210 and is conveyed to the outer ring fire air passage 130. In the rotation process of the valve core 200, the overlapping area of the port of the outer ring fire air passage 130 and the first air groove 210 is gradually increased, the ventilation volume of the outer ring fire is gradually increased, and when the port of the outer ring fire air passage 130 is completely aligned to enter the first air groove 210, the ventilation volume of the outer ring fire air passage 130 is maximum; the overlapping area of the port of the inner ring fire air passage 120 and the adapter 201 is gradually increased, the ventilation volume of the inner ring fire air passage 120 is gradually increased, and when the port of the inner ring fire air passage 120 is completely aligned to enter the adapter 201 or the second air groove 220, the ventilation volume of the inner ring fire is the maximum. In the rotation process of the valve core 200, the first air groove 210 is synchronously staggered or communicated with the port of the outer ring fire air passage 130, the switching position 201 and the port of the inner ring fire air passage 120, and the size of the superposed area is also synchronously changed, so that the firepower of big and small fire of the stove is synchronously adjusted, any firepower between the big and small fire is selected, the whole structure is simple, and the adjustment is very convenient.

In some embodiments of the present invention, the middle-lower portion of the valve cartridge 200 has a reverse tapered shape, and the diameter of the portion is gradually reduced from top to bottom. The first air groove 210, the second air groove 220, and the communication groove 230 are located on the core body of the reverse taper shape. The valve seat 100 is provided with a mounting hole 140 for mounting the valve element 200, which is formed in a reverse taper shape and is engaged with a middle lower portion of the valve element 200. The outer side wall of the valve core 200 is fully attached to the inner wall of the mounting hole 140, so that gas leakage is avoided.

In some embodiments of the present invention, a limiting groove 240 is formed in an upper outer wall of the valve core 200, and the limiting groove 240 surrounds a central axis of the valve core 200 and is formed along a circumferential direction of the valve core 200. The inner wall of the mounting hole 140 may be provided with a limiting step, and when the valve element 200 is assembled in the mounting hole 140, the limiting groove 240 is located above the limiting step, and a retaining ring and the like may be clamped at the limiting groove 240, so that the rotation stroke of the valve element 200 is limited by the cooperation of the retaining ring and the limiting step.

In some embodiments of the present invention, as shown in fig. 3 and 4, the widths D1, D2, and D3 of the first air groove 210, the second air groove 220, and the communication groove 230 are all equal, so as to ensure that the flowing amounts of the fuel gas in the first air groove 210, the second air groove 220, and the communication groove 230 are equal.

In some embodiments of the present invention, both ends of the first air groove 210, both ends of the second air groove 220, and both ends of the communication groove 230 are arc-shaped. The ports of the inlet duct 110, the inner ring fire air duct 120 and the outer ring fire air duct 130 near the valve core 200 are in a round mouth shape, and are matched with the two ends of the first air groove 210, the two ends of the second air groove 220 and the arc-shaped end part of the communication groove 230.
