In order to solve the problems of longer time and low regulation efficiency when the air outlet is sealed in the prior art. The utility model provides a governing valve and gas equipment. The specific gas appliance includes the following regulating valve.

Example one

As shown in fig. 1 and 2, the regulating valve of the present invention comprises a valve body 10, a valve core 20, and a sealing unit, wherein the valve body 10 has an air inlet 11 and an air outlet 12 communicated with a valve cavity; the valve core 20 is movably arranged in the valve cavity, and the valve core 20 can translate between a first position and a second position to regulate the fluid flow of the air outlet 12; the sealing unit is disposed on an inner wall of the valve chamber to cooperate with the valve core 20 such that the valve core 20 can close the air outlet 12 at the first position and the second position.

The valve body 10 has an inlet 11 and an outlet 12 communicating with the valve chamber. The valve spool 20 is movably disposed within the valve cavity, and the valve spool 20 is translatable between a first position and a second position to regulate fluid flow to the outlet port. The sealing unit is arranged on the inner wall of the valve cavity to be matched with the valve core 20, so that the valve core 20 can seal the air outlet at the first position and the second position. That is, even if the valve element 20 is not in direct contact with the air outlet 12, the sealing unit is disposed to be engaged with the valve element 20, so that the air outlet can be closed when the valve element 20 is at the first position and the second position, thereby achieving the purpose of indirectly sealing the air outlet. The utility model provides a governing valve, when sealed gas outlet, the time of cost is shorter, has improved regulation efficiency.

As shown in fig. 1, the fluid flows from the inlet port 11 to the first position of the valve element 20, the second position of the valve element 20 and the outlet port 12 in sequence; when the valve core 20 is in the first position, the valve core 20 can cooperate with the sealing unit to seal the air outlet 12, and when the valve core 20 is in the second position, the valve core 20 can also cooperate with the sealing unit to seal the air outlet 12. And the valve spool 20 is movable between the first and second positions to regulate the flow of fluid from the outlet port 12. Therefore, the adjusting efficiency of the adjusting valve is improved, and the purpose of sealing the air outlet 12 can be quickly achieved when the air outlet 12 needs to be sealed.

As shown in fig. 1, the sealing unit has a first sealing portion 31, the first sealing portion 31 is disposed on the inner wall of the valve chamber, and the first sealing portion 31 and the side surface of the valve core 20 can form the flow-through valve port 15, and when the valve core 20 is at the first position, the flow-through valve port 15 can be closed. In this embodiment, the overflow valve port 15 corresponds to a first position of the valve core 20 during the translation process, and the first sealing portion 31 is an overflow groove disposed on the inner wall of the valve cavity and engaged with the valve core 20, and the overflow groove extends along the movement direction of the valve core 20.

Specifically, the valve core 20 has an adjusting portion 21, the adjusting portion 21 and the flow passing groove cooperate to form the flow passing valve port 15, and the adjusting portion 21 protrudes from the surface of the valve core 20. The regulating portion 21 of the valve spool 20 is capable of sealing the spill valve port 15 when the valve spool 20 is in the first position, and is capable of regulating the flow of fluid from the outlet 12 when the valve spool 20 is translated from the first position to the second position. The flow through groove can play a certain guiding role for the movement of the valve core 20, so that the valve core 20 is prevented from rotating in the valve cavity, and the stability of adjustment is improved.

As shown in fig. 1, during the movement of the valve core 20, the flow-passing valve port 15 can be changed regularly to regulate the fluid flow of the air outlet 12. In this embodiment, the adjusting portion 21 of the valve core 20 is an inclined surface with respect to one surface of the groove bottom of the overflow groove, and the inclined surface forms an included angle with the plane of the valve core 20. When the valve core 20 moves, the distance between the adjusting portion 21 and the bottom of the flow through groove will change constantly, so that the opening of the flow through valve port 15 will change regularly, and the fluid flow of the air outlet 12 can be adjusted.

As shown in fig. 1 and 2, during the movement of the valve core 20, the flow-passing valve port 15 has at least two variable sides, and the variable sides are parallel to each other to linearly regulate the fluid flow of the outlet 12. In this embodiment, the first side 211 of the two changing sides is located on the adjusting portion 21 of the valve core 20, and the second side 311 is located on the bottom of the overflow groove, when the two moving sides move relative to each other, the two sides are parallel to each other, and the distance between the two sides will be continuously close to or far away from each other on the cross section of the overflow valve port 15. When the valve core 20 translates in the valve cavity, the regulating portion 21 of the valve core 20 translates relative to the overflow groove, and the first side 211 moves relative to the second side 311, so that the change of the overflow valve port 15 can be controlled. The two changing edges are parallel to each other, so that the overflowing valve port 15 can be ensured to be continuously and linearly changed.

It should be noted that the above-mentioned variable side is an edge constituting the spill valve port 15, that is, an edge determining the opening degree of the spill valve port 15, and may be thought of as a "gate" at the spill valve port 15, particularly, a first side 211 provided on the regulating portion 21 of the valve body 20, like a bottom edge of the gate. When the spool 20 moves relative to the valve chamber, the first side 211 of the different position on the spool 20 acts as the "bottom edge of the gate" at that time.

As shown in fig. 1, when the valve body 20 is at the first position, the first seal portion 31 is pressed against the side surface of the valve body 20. In this embodiment, when the valve element 20 is in the first position, the spill valve port 15 needs to be sealed so that the flow through the outlet 12 is zero. To ensure the reliability of the sealing, the first sealing portion 31 is pressed against the valve body 20. The end of the adjusting part 21 of the valve core 20 can be provided with a sealing gasket, so that a better sealing effect can be achieved in the process of extruding with the overflowing groove.

As shown in fig. 1, when the area of the overflow valve port 15 is smaller than the area of the air inlet 11 and the area of the air outlet 12, the overflow valve port 15 has a function of adjusting the fluid flow rate of the air outlet 12. When the flow rate of the fluid introduced into the regulating valve is constant, the cross-sectional area of the overflowing valve port 15 is controlled, so that the flow of the fluid passing through the overflowing valve port 15 can be controlled, the area of the air inlet 11 is larger than that of the overflowing valve port 15, the cross-sectional area of the overflowing valve port 15 becomes the only factor influencing the flow of the fluid passing through the overflowing valve port 15, and the control is more convenient. Meanwhile, the area of the air outlet 12 needs to be larger than that of the overflow valve port 15, so that the air outlet 12 does not influence the flow of the fluid passing through the overflow valve port 15. So that the flow rate of the fluid passing through the outlet port 12 can be relatively accurately secured, and the efficiency of the regulation is improved.

As shown in fig. 1, the sealing unit has a second sealing portion 32, and when the valve core 20 is in the second position, the second sealing portion 32 has an opening, and the valve core 20 can be connected with the opening in a sealing manner. In this embodiment, the second position of the valve core 20 corresponds to the position of the outlet 12 of the regulating valve, and the second sealing portion 32 is a gasket disposed in the valve chamber and corresponding to the position of the outlet 12. When the valve element 20 moves to the second position, the end of the valve element 20 presses against the second sealing portion 32 to seal the air outlet 12.

Specifically, the end of the valve core 20 abutting against the second sealing portion 32 is shaped as a conical structure, and when the conical structure abuts against the second sealing portion 32, the small end of the conical structure is inserted into the opening of the second sealing portion 32 to close the air outlet 12. Set up the toper structure and can play better sealed effect.

As shown in fig. 1, the opening can regulate the fluid flow of the outlet 12 when the area of the opening is smaller than the area of the flow-through valve port 15. In this embodiment, the area of the opening corresponds to the gap between the conical structure on the valve core 20 and the conical structure when the conical structure is inserted into the opening, and when the area of the minimum cross section of the gap is smaller than the area of the minimum cross section of the flow-passing valve port 15, the fluid flow at the air outlet 12 can be adjusted.
