Abstract
The utility model discloses a novel air valve applicable to liquid replenishment. The air valve comprises an electromagnetic valve, a liquid inlet source, a liquid storage tank, a liquid feed tank, a plastic sheet, a metal gasket, a spring and a sealing ring, wherein the electromagnetic valve adopts a two-way electromagnetic valve; the height of the liquid inlet source is greater than that of the liquid feed tank; the spring is arranged between a metal upper cover and the metal gasket; the plastic sheet is arranged between the metal gasket and a metal lower cover; the sealing ring is arranged between the plastic sheet and the metal upper cover. The air valve has the benefits that although pressure in the sealing space is constantly changed during the process of switching of the electromagnetic valve, pressure in a liquid feed pipe and the liquid storage tank is slightly changed, so that the pressure of lower section equipment connected with the liquid feed pipe cannot be affected, and further the operation reliability of the equipment is improved.
Description
Technical field
The utility model relates to crystal silicon solar batteries sheet and makes field, relates to particularly a kind of novel Air valves that is applicable to liquid supply.
Background technique
At present, polysilicon solar battery slice preparation generally includes making herbs into wool, diffusion, wax spray, etching, PECVD plated film and silk-screen printing technique.Conventionally adopt sour making herbs into wool and wet-etching technology preparation, because it has the advantage of low-cost high-efficiency.Above-mentioned two kinds of techniques mainly adopt the mixture system of hydrofluoric acid and nitric acid to prepare matte.Along with needing timely fluid infusion in production process, just can reach the matte reflectivity of the polysilicon chip of preparing in controlled range.In the fluid infusion system of existing equipment, utilize electromagnetic valve vacuum system break-make, by vacuum system, act directly on hypomere equipment container inside, container internal pressure is reduced, by liquid suction container.In process of production, hypomere equipment container is because of vacuum system break-make aperiodically for existing equipment, and internal pressure is changing continuously, and easily to hypomere equipment, work causes harmful effect.
Summary of the invention
For above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of Air valves that is applicable to liquid supply, by on the control of solenoid valve can in the case of not affecting the internal pressure of hypomere equipment simply, rapidly fluid infusion container is realized and is started freely or stop liquid make-up, improve the operational reliability of equipment.
In order to address the above problem, the utility model provides a kind of Air valves that is applicable to liquid supply, and this Air valves comprises solenoid valve, feed liquor source, store up liquid bath, feed tank, plastic tab, metallic shim, spring and seal ring, wherein said solenoid valve adopts two-way electromagnetic valve; It is high that the aspect ratio in described feed liquor source is stored up liquid bath; Described spring is placed between metal top cover and metallic shim; Described plastic tab is placed between metallic shim and metal lower cover; Described seal ring is placed between plastic tab and metal top cover.
The beneficial effects of the utility model are in the process of switching at solenoid valve, although seal space internal pressure changes constantly, but only can there is very little change in feed pipe and the pressure of storing up in liquid bath, thereby can not affect the pressure of the hypomere equipment being connected with feed pipe yet, improve equipment reliability of operation.
Accompanying drawing explanation
The structural drawing of the Air valves that is applicable to liquid supply in accompanying drawing 1 the utility model when logical atmosphere
In figure: 1 represents metallic shim; 2 represent spring; 3 represent seal ring; 4 represent plastic spacer; 5, liquid bath is stored up in 7 representatives; 6 represent feed tank
The structural drawing of the Air valves that is applicable to liquid supply in accompanying drawing 2 the utility model when logical vacuum.
Embodiment
By reference to the accompanying drawings 1 and accompanying drawing 2 technological scheme that the utility model is provided be described in further detail.
When the logical atmosphere of solenoid valve as shown in Figure 1, metal top cover inner sealing space is normal atmosphere (An), now the spring of moderate compression has a downward pressure to metallic shim, metallic shim is tightly pushed down plastic tab, the seal ring of plastic tab and thin slice below is fitted tightly, the liquid of storing up in liquid bath cannot flow in feed pipe, and now this product plays and stops feed flow function.
When the logical appropriate vacuum of solenoid valve as shown in Figure 2, metal top cover inner sealing space is appropriate negative pressure, plastic tab has been produced to pulling force upwards, and by the suitable adjustment to negative pressure of vacuum, the pulling force upwards that negative pressure is produced plastics is a bit larger tham the downward pressure that metallic shim applies it.The sealed circle in plastic tab two ends firmly kills, and makes plastic tab intermediate portion under the effect of pulling force, warpage slightly, and no longer, with the laminating of lower seal circle, the liquid of storing up in liquid bath just flows into feed pipe continuously.
Claims (1)
1. a novel Air valves that is applicable to liquid supply, this Air valves comprises solenoid valve, liquid bath is stored up in feed liquor source, feed tank, plastic tab, metallic shim, spring and seal ring, is characterized in that: described solenoid valve adopts two-way electromagnetic valve; It is high that the aspect ratio in described feed liquor source is stored up liquid bath; Described spring is placed between metal top cover and metallic shim; Described plastic tab is placed between metallic shim and metal lower cover; Described seal ring is placed between plastic tab and metal top cover.
