Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model discloses the not tight condition of valve plate and sealing washer seal that adopts the sealed existence of mechanical type to current inflation valve provides an air bag formula sealing device, air bag formula sealing device sets up in the inner chamber of inflation valve body 4, and its structure is as shown in figure 1, including aerifing placenta 1 and restriction subassembly 2, it has for to aerify placenta 1 aerify and make its pressure boost inflation to aerifing placenta 1 by the full-fled first state, and will aerify the second state that contracts after placenta 1 loses heart, first state is arranged in the gaseous circulation in the separation inflation valve inner chamber, the second state is arranged in passing through the inflation valve inner chamber gas, restriction subassembly 2 sets up aerify the outside of placenta 1 for the restriction aerify placenta 1's expansion range, so, can play the effect that the separation air current passes through to the inner chamber of inflation valve's valve body 4 after aerifing placenta 1 is full of inflation valve to reach safe airtight effect.
In a specific embodiment, the inflated placenta 1 is a bladder structure made of rubber material, the inflated placenta 1 has two states, a first state and a second state, wherein the first state is an expanded state when the inflated placenta 1 is filled with gas, and the second state is a tightened state after the gas in the inflated placenta 1 is released; when the inflatable placenta 1 is in the first state, the inflatable placenta 1 can completely block the inner cavity of the valve body 4 of the inflation valve, so that the gas circulation in the inner cavity of the inflation valve can be blocked, the cutting-off effect is achieved, meanwhile, the inflatable placenta 1 is made of rubber materials, the flexible sealing effect is achieved, the loose condition of the existing mechanical sealing can be effectively improved, and the sealing performance of the inflation valve is improved.
In a specific embodiment, the inflatable placenta 1 is disc-shaped in the first state, and the circumferential edge of the inflatable placenta 1 abuts against the periphery of the inner cavity of the valve body 4 of the inflation valve, so that the inflatable placenta 1 can completely block the air in the inner cavity of the inflation valve.
In a specific embodiment, the inflated placenta 1 is flat in the second state and is disposed on a side wall of the internal cavity of the inflation valve, and when the air in the inflated placenta 1 is completely released, the volume of the inflated placenta 1 is reduced to a minimum state, the air flow passing space of the internal cavity of the inflation valve is released to the maximum extent, so that the air flow can pass smoothly.
In a specific embodiment, one side (generally the bottom) of the inflated placenta 1 is provided with an air hole for inflating or deflating the placenta, a valve core 3 is connected to the air hole, the other end of the valve core 3 is arranged through a valve body 4 of an inflation valve, and the other end of the valve core 3 is connected with an inflation assembly.
It will be appreciated that the above-described inflation assembly serves to inflate the placenta 1, and thus, the inflation assembly may be used with existing mature products, such as a pump, and the like, only for the inflation function. When the air-filled placenta 1 needs to be deflated, only the valve core 3 needs to be pulled out, and the operation is very convenient.
In a particular embodiment, in order to better perform the sealing effect of the inflated placenta 1, it is necessary to limit the state of the inflated placenta 1 when it is filled with gas, and therefore we have arranged the limiting assembly 2 outside said inflated placenta 1.
Specifically, as shown in fig. 2, the limiting component 2 comprises a first steel grid and a second steel grid, and the first steel grid and the second steel grid are respectively arranged on two sides of the inflatable placenta 1. Preferably, the first steel grating and the second steel grating are formed by intersecting a plurality of cross beams 2.1 and a plurality of longitudinal beams 2.2, and both ends of the cross beams 2.1 and the longitudinal beams 2.2 are fixed on the inner cavity wall of the inflation valve.
In a specific embodiment, the first steel grid and the second steel grid have the same shape, that is, the plurality of grids distributed on the first steel grid and the second steel grid are corresponding, so that when the inflated placenta 1 is in the second deflated state, the airflow can smoothly pass through, and the service function of the inflation valve is ensured.
