fig. 2 is an enlarged view of a structure a in fig. 1.
In the figure: the air-tight valve comprises a valve body 1, a chamber 2, a first spring 3, a moving block 4, a support rod 5, an air bag 6, a vent pipe 7, a water inlet 8, a sealed cavity 9, a base 10, a valve clack 11, a water outlet 12, a partition plate 13, a second spring 14, a sealing plug 15 and a connecting rod 16.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-2, a pressure sealing check valve comprises a valve body 1, a chamber 2 is fixedly connected at the center of the upper end of the valve body 1, a water inlet 8 is arranged at the lower side of the valve body 1, a water outlet 12 is arranged at the upper end of the valve body 1, a first spring 3 is fixedly connected in the chamber 2, a movable block 4 is fixedly connected at the other end of the first spring 3, the movable block 4 is slidably connected in the chamber 2, a support rod 5 is fixedly connected at one end of the movable block 4 away from the first spring 3, a valve flap 11 is fixedly connected at one end of the support rod 5 away from the movable block 4, so that the valve flap 11 can be lifted under the action of the first spring 3 by water impact to achieve water outflow, a bearing part is arranged between the two ends of the valve flap 11 and the valve body 1, the bearing part comprises two bases 10, the bases 10 are respectively fixedly connected to, the valve flap 11 is connected on the notch of the base 10 in a sliding manner, the valve flap 11 is arranged on the notch of the base 10, so that the valve flap 11 and the base 10 form a closed and sealed state for the water inlet 8 and the water outlet 12, a sealing part is arranged in the base 10, the sealing part comprises a sealing cavity 9, a second spring 14 is fixedly connected in the sealing cavity 9, the other end of the second spring 14 is fixedly connected with a sealing plug 15, the sealing plug 15 is connected in the sealing cavity 9 in a sliding manner, a connecting rod 16 is fixedly connected on one surface of the sealing plug 15 far away from the second spring 14, the connecting rod 16 penetrates through the base 10, therefore, when the valve flap 11 rises, the opening force of the second spring 14 is enabled as the valve flap 11 is arranged above the connecting rod 16, the lamp hook pushes the connecting rod 16 and the sealing plug 15 to rise, the air bag 6 is arranged between the two ends, 13 fixed connection of baffle is on base 10, because baffle 13 is in the top of gasbag 6, make gasbag 6 can guarantee when aerifing spacing gasbag 6 between valve clack 11 and base 10, 6 fixed connection of gasbag is on base 10, fixedly connected with breather pipe 7 between gasbag 6 and the sealed chamber 9, because breather pipe 7 connects the lower extreme at sealed chamber 9, make when sealing plug 15 descends, can promote the air in the sealed chamber 9 and pass through in breather pipe 7 gets into gasbag 6, because the air in the gasbag 6 makes gasbag 6 increase, thereby reach and fill the space between valve clack 11 and the base 10, reach better sealed effect.
The utility model discloses in when water entered from water inlet 8, because branch 5 fixed connection is passed through on movable block 4 in valve clack 11 upper end, because the first spring of fixedly connected with 3 on the movable block 4, and movable block 4 slides in cavity 2, make when water flows in from water inlet 8, the pressure of water can strike valve clack 11, make valve clack 11 rise, can pass through rivers from this, it goes out smoothly from delivery port 12 to reach water, when water of water inlet 8 does not have pressure, first spring 3 then can make valve clack 11 descend on the falling base 10 because elasticity, from this just reached effective flowing to rivers put and cut to.
When the valve flap 11 rises, because the connecting rod 16 in the base 10 is not limited by the valve flap 11, the connecting rod 16 passes through the elasticity of the second spring 14 below the sealing plug 15 fixedly connected, the sealing plug 15 and the connecting rod 16 are pushed to rise, the air in the sealing cavity 9 is reduced due to the rising of the sealing plug 15, the air in the air bag 6 connected through the vent pipe 7 enters the sealing cavity 9, the air bag 6 is reduced, and the valve flap 11 falls to fall on the base 10, the connecting rod 16 is pressed downwards due to the gravity of the valve flap 11, the sealing plug 15 moves downwards, so that the air in the air bag 6 is filled, and the filled air bag 6 fills the gap between the valve flap 11 and the base 10 and is sealed to achieve the backflow of water.
