Detailed Description

The invention is further described with reference to the following figures and embodiments.

Referring to fig. 1, the invention discloses a deep sea water inlet valve, which mainly comprises a valve main body, a control mechanism and the like.

Wherein the valve main body comprises a water inlet valve body 1, a water inlet spring 2 and a water inlet valve core 3 which are arranged in the water inlet valve body 1, one end of the water inlet valve body 1 is closed, the other end of the water inlet valve body is respectively provided with a transverse outlet, a longitudinal inlet and a pin shaft hole positioned below the transverse outlet, a steel ball 4 is arranged in the pin shaft hole, the outer wall surface of the water inlet valve core 3 is provided with a pit corresponding to the steel ball 4, the concave pit has the same diameter with the steel ball 4, the depth is 1/3-1/2 of the diameter of the steel ball 4, the outer wall of the water inlet valve body 1 is transversely provided with a connecting sleeve, the outlet of the pin shaft hole is positioned at the center of the connecting sleeve, one end of the water inlet spring 2 is fixed at the closed end of the water inlet valve body 1, the other end is connected with the water inlet valve core 3, the inner wall of the water inlet valve body 1 is provided with a step part which is close to the transverse outlet and used for limiting the water inlet valve core 3, and a sealing ring is arranged on the water inlet valve core 3 to realize the sealing of the water inlet valve core 3 and the inner wall surface of the water inlet valve body 1.

The control mechanism comprises an electric explosion valve body 7 and an electric explosion valve core 8 arranged in the electric explosion valve body 7, wherein an electric explosion head 6 and an electric explosion plug 10 are respectively arranged at two ends of the electric explosion valve body 7, an electric explosion spring 9 is arranged between the electric explosion valve core 8 and the electric explosion plug 10, a connecting shaft positioned in a connecting sleeve is transversely arranged on the outer wall of the electric explosion valve body 7, a pin shaft hole communicated with the inner cavity of the electric explosion valve body 7 is formed in the center of the connecting shaft, a pin shaft 5 abutted against a steel ball 4 is arranged in the pin shaft hole, a flange part is arranged at the bottom end of the electric explosion valve core 8, a step part for limiting the flange part is arranged on the inner wall of the electric explosion valve body 7 close to the pin shaft hole, and a sealing ring is arranged on the electric explosion valve core 8 so as to seal the inner wall surface of the electric explosion valve body 8 and the electric explosion valve body 7. Wherein the pin shaft hole on the water inlet valve body 1 and the pin shaft hole on the electric explosion valve body 7 have the same aperture and accommodate the horizontal movement of the pin shaft 5.

The valve body and the control mechanism of the invention are controlled and conducted through the steel ball 4 and the pin shaft 5.

Fig. 1 is a closed state of the water inlet valve body 1, which is also an initial state of the water inlet valve body 1: when the water inlet valve body 1 is not opened, the inlet of the water inlet valve body is contacted with seawater, the water inlet valve core 3 bears seawater pressure, the pressure acts on the steel ball 4, the steel ball 4 cannot move rightwards under the limitation of the pin shaft 5 and the electric explosion valve core 8, and therefore the water inlet valve core 3 can bear high seawater pressure. In order to avoid the deformation of the stressed part under the pressure of seawater, except the water inlet spring 2, the electric explosion head 6, the electric explosion spring 9 and the electric explosion plug 10, other parts are made of high-hardness alloy materials, particularly the water inlet valve core 3 and the steel ball 4, and the hardness HRC of the parts is not less than 30.

Fig. 2 shows the open state of the water inlet valve body 1: firstly, the electric explosion head 6 is ignited to generate gas and impact force, and the electric explosion valve core 8 is pushed to overcome the friction force of the pin shaft 5 and the electric explosion valve core 8 to move downwards. When the electric explosion valve core 8 moves to the position shown in the figure, the right side of the pin shaft 5 is not limited, so the steel ball 4 and the pin shaft 5 move to the right under the action of the water inlet valve core 3, and simultaneously the water inlet valve core 3 moves upwards to communicate an inlet and an outlet to complete the opening action.

The valve opening device has the function that the valve opening process can be completed by small acting force in a deep sea high-pressure environment. Under the condition that the stressed part of the water inlet valve body 1 is not deformed and the working capacity of the electric explosion head 6 is enough, the higher the seawater back pressure is, the more the opening of the valve is facilitated.
