TECHNICAL FIELD
[0001] The utility model belongs to control valve technical field, concretely relates to a self -stop control valve for grain moistening vehicle. BACKGROUND
[0002] In the grain moistening stage of the brewing process of Maotai-flavor liquor, boiling water is poured into the grain pile for grain moistening. At present, a certain amount of boiling water is delivered into the grain pile by using a grain moistening water injector. However, in the actual use process, the water injection is stopped by manual control, and due to the influence of human factors, the actual water injection amount is different each time. Different water injection amounts can significantly affect the liquor quality and raw material processing. For example, too much grain moistening water can cause the sugar in the raw material to become diluted after saccharification, thereby reducing the alcohol content of the final liquor. Too much water can cause the sugar in the liquor to be too much, resulting in a sweet taste, low acidity of the liquor body, and poor overall taste. In addition, too much water can cause the acid to rise too rapidly during the fermentation process, further affecting the flavor of the liquor. Moreover, too much water can cause the loss of volatile substances, thereby affecting the release of the aroma of the liquor.
[0003] Therefore, it is necessary to design a control valve that can control the stopping of water injection, so that the water injection amount is stable within a very small fluctuation range each time. SUMMARY

[0029] In order to make the technical personnel in the prior art can better understand the utility model, the utility model technical scheme is further explained below with the embodiment and the drawing.
[0030] As Figures 1-3 The utility model discloses a self -stop control valve for grain moistening vehicle, including valve body 1, valve body 1 is equipped with valve core cavity 2, one -way valve cavity 3, valve body inlet 4, steering passage main waterway 5, steering passage branch waterway 6 and valve body outlet 7;
[0031] Valve core cavity 2 with valve body inlet 4, steering passage branch waterway 6 and valve body outlet 7 communicate, one -way valve cavity 3 input end with valve body inlet 4 side communication, one -way valve cavity 3 output end with steering passage main waterway 5 communicate, and steering passage branch waterway 6 output end and steering passage main waterway 5 side communication;
[0032] Valve core cavity 2 is equipped with two moving grooves 21 symmetrically, and one of moving grooves 21 is equipped with delay function cavity inlet 22 and delay function cavity outlet 23, and delay function cavity inlet 22 and delay function cavity outlet 23 communicate, and delay function cavity outlet 23 with steering passage branch waterway 6 input end communication,
[0033] Valve core 8 is installed inside valve core cavity 2, and ear plate 81 is connected in two moving grooves 21, return spring 82 is connected between moving groove 21 without setting delay function cavity inlet 22 and ear plate 81, and screw rod 83 is integrated on the top of valve core 8, handle 84 is installed on screw rod 83, and valve cover 9 with the same size as valve core 8 is installed on valve body 1.
[0034] One-way valve cavity 3 is screw-connected with bolt 31, bolt 31 is connected with compression spring 32, and valve plug 33 is connected at the end of compression spring 32.
[0035] In this embodiment, when the self-stopping control valve used in the grain lubricating vehicle is used, the control valve presents three states, one is standby state, two is starting state, and three is stopping state.
[0036] In standby state, valve core 8 blocks delay function cavity inlet 22 and steering passage branch waterway 6 inlet, so the water flow in valve body 1 cannot flow, and the water pressure in valve body inlet 4 is constant, it is necessary to point out that the water pressure in constant state or standby state cannot flush valve plug 33, so the water flow cannot enter one-way valve cavity 3, and the water flow is discharged from steering passage main waterway 5, the water pressure in valve body 1 does not change, and the water supply equipment connected through valve body inlet 4 does not start without change of water pressure, and standby instruction is obtained.
[0037] For example, Figure 4 And Figure 5As shown, in the start-up state, the handle 84 needs to be manually turned counterclockwise. The rotation of the handle 84 drives the valve core 8 to rotate in the valve core cavity 2 via the screw rod 83. The rotation of the valve core 8 connects the input end of the delay function cavity inlet 22 and the input end of the turning channel branch water passage 6 with the valve core cavity 2. The water in the valve core cavity 2 then flows from the delay function cavity inlet 22 and the turning channel branch water passage 6 into the turning channel main water passage 5, and after passing through the other side of the valve core 8, it is discharged from the valve body outlet 7. Because of the water discharge, the water pressure inside the valve body 1 decreases. The water supply equipment connected through the valve body inlet 4 detects the change in water pressure and starts to start, receiving the water supply command and starting to supply water. In the water supply state, the water pressure immediately begins to rise, while the valve core 8 in the valve core cavity 2 returns to its original position. Under the effect of spring 82, it begins to slowly move back to its standby position, blocking the input ends of the branch water passage 6 of the turning channel and the inlet 22 of the delay function chamber. However, the water supply from the water supply equipment causes the water pressure to rise, so the water pressure can open the valve plug 33. The water flows from the one-way valve chamber 3 into the main water passage 5 of the turning channel and is discharged from the valve body outlet 7 from the other side of the valve core 8, achieving the purpose of continuous water supply. When the water supply equipment reaches the set water supply volume, the water supply equipment stops, the water pressure inside the valve body 1 returns to normal, and under the effect of spring 32, the valve plug 33 re-seals the inlet end of the one-way valve chamber 3, so the water flow can no longer enter the main water passage 5 of the turning channel, thereby achieving the purpose of stopping water supply. The valve body 1 achieves the purpose of self-stopping.
[0038] Furthermore, the opening and closing pressure of the valve plug 33 can be adjusted according to the actual situation. For example, the spring 33 of different strengths can be replaced, or the screwing depth of the bolt 31 can be changed so that the contraction strength of the spring 33 changes due to the change in its own length. Alternatively, the length of the bolt 31 or the valve plug 33 can be changed so that it can be adapted to different pressures of the water supply equipment.
[0039] like Figure 6 As shown, in the stopped state, the handle 84 needs to be manually turned clockwise once. This state is a manual intervention stop, which is often used in situations where abnormalities occur or water supply needs to be stopped in advance. The clockwise rotation of the valve core 8 directly blocks the input end of the valve body outlet 7. The water that cannot flow out and the continuous water supply of the water supply equipment cause the water pressure inside the valve body 1 to increase. When the water supply equipment detects that the water pressure has increased to the set value, the water supply program terminates.
[0040] The valve cover 9, bolt 31 and valve plug 33 are all fitted with sealing rings 10. This design ensures a sealing and waterproof effect. In fact, sealing and waterproof measures can also be considered depending on the specific situation.
[0041] Preferably, the adjusting screw 11 is installed at the communication position between the time delay function cavity inlet 22 and the time delay function cavity outlet 23, and the adjusting screw 11 is screwed to the valve cover 9, through adjusting the blocking area of the adjusting screw 11 inserted between the time delay function cavity inlet 22 and the time delay function cavity outlet 23, the water flow between the time delay function cavity inlet 22 and the time delay function cavity outlet 23 can be adjusted, and the time length of the time delay can be adjusted, and actually, the installation and sealing measures of the adjusting screw 11 can be considered according to the specific conditions.
[0042] Preferably, the limit groove 12 is arranged at the bottom center position of the valve core cavity 2, and the limit disc 85 matched with the limit groove 12 is integrally connected to the valve core 8, through the design, the rotation of the valve core 8 can be stable, and the stress effect can be guaranteed, and the service life of the whole can be enhanced, and actually, the position positioning structure of the valve core can be considered according to the specific conditions.
[0043] Preferably, the start-stop mark is arranged on the valve cover 9, through the design, the rotation direction can be quickly understood by the related users, and actually, the drawing method and shape style of the start-stop mark can be considered according to the specific conditions.

Any person skilled in the art can modify or change the above embodiment without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the utility model should be covered by the claims of the utility model.
