Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 5, the present invention provides a 0 degree double injection synchronous plug valve, comprising:
the valve body 100 is provided with an air inlet passage 110, a main fire passage 120 and a secondary fire passage 130. Specifically, the fire outlet parallel arrangement of main fire channel 120 and time fire channel 130, wherein, time fire channel 130 is located the center axis of valve body 100, and main fire channel 120 is located one side of valve body 100, and inlet channel 110 is then vertical sets up in the bottom of valve body 100, and inlet channel 110 passes through valve body inlet hole 111 and communicates with the external world, and the plug valve that this application provided is applicable to the use of integrated kitchen.
And the valve core 140 is installed in the valve body 100, the valve core 140 can rotate relative to the valve body 100, and the valve core 140 is provided with a vent hole for cutting off or conducting communication between the valve core 140 and the valve body 100. Wherein, the air vent includes: a valve core air inlet hole 141 communicated with the air inlet channel 110 and the valve body air inlet hole 111, a valve core air outlet hole 142 communicated with the valve core air inlet hole 141, a valve body main air outlet hole 101 communicated with the main fire channel 120, a valve body secondary air outlet hole 102 communicated with the secondary fire channel 130, and a valve core fire protection hole 143 communicated with the main fire channel 120 and the secondary fire channel 130.
The valve core air inlet hole 141 is directly communicated with the secondary fire channel 130, the main fire channel 120 is communicated with the valve core air inlet hole 141 through the valve core air outlet hole 142, and due to the fact that the valve core air inlet hole 141 can averagely divide entering fuel gas, the fuel gas amount entering the secondary fire channel 130 is equal to that entering the main fire channel 120, and the effects that the fire amounts of the main fire outlet 121 and the secondary fire outlet 131 are kept consistent and can be synchronously changed are achieved.
Specifically, when the gas stove is ignited, gas enters the gas inlet channel 110 through the valve body gas inlet hole 111, and is divided into two parts after passing through the valve core gas inlet hole 141, wherein half of the gas directly enters the secondary fire channel 130, and the other half of the gas enters the main fire channel 120 after passing through the valve core gas outlet hole 142.
In actual operation, the valve core intake hole 141 and the valve body intake hole 111 at the initial position are in a non-conduction state, and gas cannot enter the valve core intake hole 141 from the valve body intake hole 111, and the valve core 140 is located at the 0 ° position at this time.
The spool 140 rotates 0 ° -90 °: when the valve core 140 rotates relative to the valve body 100, the valve core air inlet hole 141 and the valve body air inlet hole 111 are gradually communicated, so that fuel gas can enter the valve core air inlet hole 141 from the valve body air inlet hole 111 and evenly flow into the main fire channel 120 and the secondary fire channel 130, and finally, the main fire outlet 121 and the secondary main fire outlet synchronously fire. In the process of the rotation of the valve core 140, the area of the overlapped hole between the valve body air inlet hole 111 and the valve core air inlet hole 141 is gradually increased along with the rotation of the valve core 140, until the valve core 140 rotates by 90 degrees, the area of the hole between the valve core air inlet hole 141 and the valve body air inlet hole 111 reaches the maximum value, the air inflow entering the valve core air inlet hole 141 from the valve body air inlet hole 111 reaches the peak value, and the fire outlet amount of the main fire hole and the secondary fire hole is the maximum at this time.
The spool 140 rotates 160 ° -180 °: after the valve core 140 rotates by 90 degrees and the fire amount reaches the maximum, the valve core 140 continues to rotate, at this time, the area of the overlapped hole between the valve core air inlet hole 141 and the valve body air inlet hole 111 gradually decreases, and the air intake amount also decreases, so the fire amounts of the main fire outlet 121 and the secondary fire outlet 131 also synchronously decrease, until the valve core 140 rotates to the range of 160 degrees to 180 degrees, the valve body air inlet hole 111 and the valve core air inlet hole 141 are not communicated, the valve body air inlet hole 111 and the valve core fire retaining hole 143 are communicated with each other, after gas enters from the valve body air inlet hole 111, the gas enters the main fire channel 120 and the secondary fire channel 130 through the valve core fire retaining hole 143, and finally, after passing through the valve body main air outlet hole 101 and the valve body secondary air outlet hole 102, the main fire outlet 121 and the secondary fire outlet 131 synchronously fire. In addition, because the diameter of the valve core fire-protecting hole 143 is small, and the air input is also small, the valve core fire-protecting hole 143 plays a role in keeping the gas stove in a small fire state, and the flame is not extinguished.
In summary, when the valve core 140 is between 0 ° and 90 °, as the rotation angle increases, the main fire outlet 121 and the secondary fire outlet 131 of the valve body 100 synchronously fire, and the synchronous fire outlet amount is changed from small to large; when the valve core 140 rotates to close from 90 degrees, the synchronous fire outlet quantity of the main fire outlet 121 and the secondary fire outlet 131 of the valve body 100 gradually decreases until the valve core is closed, wherein when the valve core 140 is positioned in the interval of 160-180 degrees, gas enters the main fire channel 120 and the secondary fire channel 130 from the fire protection hole 143 of the valve core, and at the moment, the plug valve is in a fire protection state, which shows that the plug valve always keeps a small fire state on a gas stove and cannot be extinguished.
Preferably, the main fire channel 120 includes a first valve body air outlet channel 122 and a second valve body air outlet channel 123, axes of the first valve body air outlet channel 122 and the second valve body air outlet channel 123 are not on the same straight line, and further, the first valve body air outlet channel 122 and the second valve body air outlet channel 123 are conducted by the main valve body air outlet hole 101, that is, after entering the main fire channel 120, the fuel gas passes through the first air outlet channel and the main valve body air outlet hole 101, reaches the second valve body air outlet channel 123, and finally is ejected outwards from the main fire hole.
Preferably, the valve further comprises a valve rod 150, the head of the valve rod is connected with the valve core 140, the tail of the valve rod is connected with a rotating handle 160, the rotating handle 160 drives the valve core 140 to rotate, a notch is arranged at the position of the rotating handle 160 to serve as an indicating surface 161, an indicating groove which is consistent with the axial direction of the valve body 100 is further arranged on the indicating surface 161, when the valve core 140 is located at an initial position of 0 degree, the indicating surface 161 is vertically upward, and through the arrangement of the indicating surface 161, an operator can clearly know how many angles the rotating handle 160 rotates, so that the rotating angle of the valve core 140 is judged, and the convenience in use is improved.
Preferably, the spool 140 includes a spring cavity 170 and a vent cavity 180, wherein the vent is located in the vent cavity 180, and the head of the stem 150 is fitted with a spring 151, the spring 151 being located in the spring cavity 170.
In addition, the plug valve that this application provided, its connected solenoid valve that is used for controlling the admission passage 110 break-make condition is external, is independent mutually between whole valve body 100 and the solenoid valve promptly, establishes the plug valve at valve body 100 in for the solenoid valve, and the plug valve inner structure of this application is simpler, has consequently improved the efficiency when producing, changes the solenoid valve when also being convenient for follow-up maintenance, has improved the convenience.
