Abstract
The utility model provides a novel one-way valve which comprises a valve body, a valve core with valve ports and side ports and a valve cap connected with the valve core. The area of a valve disk is equal to or bigger than the area of the valve cap, so the access of air is labor-saving, particularly when the differential pressure is relatively small. The work efficiency of the one-way valve can be improved, the working time can be shortened, the machinery friction losses can be reduced and the energy can be saved when the novel one-way valve is used.
Description
The utility model relates to a kind of one-way valve.
Common one-way valve operating principle is that to act on the pressure of spool both sides unequal: when one-way valve was opened, the pressure of valve opening side (outside) was greater than the inboard, and the body (or liquid) of calming the anger this moment enters inboard (for example gas tank) by one-way valve; When closed check valve, inboard pressure is greater than the outside, and then spool withstands valve opening, and gas (or liquid) can not flow backwards.Usually, spool outside lifting surface area is less than inboard lifting surface area.Situation with gas tank is an example, reaches certain pressure in order to make the gas in the gas tank, must impose higher pressure in the one-way valve outside, so that the enough pressure reduction that spool is opened to be provided.When pressure reduction hour, gas injection difficulty relatively then, the time that reaches setting pressure is also longer, thereby makes mechanical wear too fast, and wastes energy.
The purpose of this utility model is to overcome above-mentioned difficulties and a kind of novel one-way valve is provided.This one-way valve can action easily under the less situation of the outside and inside pressure difference, air inlet is more laborsaving.
The purpose of this utility model reaches by following technical solution: it comprises that a valve body, one have the spool of valve disc, a valve gap that is connected with spool.The side opening that spool has valve opening and is connected with valve opening.The valve disc area equals the valve gap area at least.
Compared with prior art, the utlity model has following advantage: 1. because the outside pressure of valve is relevant with spool effective lifting surface area vertically with outside pressure, the inside pressure of valve is relevant with valve gap effective lifting surface area vertically with inboard pressure, suitably adjust both area ratios, can accomplish that air inlet is laborsaving.And shorten period of intake greatly; 2. because air inlet is laborsaving and the time is short, the whole system operation efficient and the degree of reliability have been improved; 3. avoid too much mechanical wear, prolonged mechanical working life; 4. energy saving.
The utility model is described in further detail below in conjunction with embodiment.
Fig. 1 is embodiment's schematic representation of the present utility model.Can see that on scheming a spool (14) is arranged in the valve body (5), an axial valve opening (13) is arranged in the spool (14), valve opening (13) is connected with side opening (12).End at spool is a valve disc (1), and the other end has a core bar (10), and valve gap (9) is installed on the core bar (10).The two ends of valve body (5) have screw thread (3) and (7) respectively, are connected with inboard (for example gas holder) with the outside (for example compressed air line) respectively.Also can on valve body (5), add a body cap (2) again, have threaded hole (16) on the body cap (2), to adapt to the connecting pipeline of different-diameter.When the pressurized air that comes from source of compressed air enters cavity (15) by connecting pipeline, valve disc (1) is subjected to a pressure, when this pressure greater than inboard gas during to the pressure of valve gap (9), spool (14) moves down, side opening (12) exceeds the lower end surface of valve body (5), and pressurized air enters the inboard of one-way valve by valve opening (13), side opening (12).When the pressurized air of inboard is gone up suffered pressure to the pressure of valve gap (9) greater than outside valve disc (1), stressed the moving up of spool (14), valve gap (9) contacts with plane (8), and then Nei Ce pressurized air can not flow backwards away.In order to make spool (14) hour can in time get back to closed position, a spring (6) can be installed between valve disc (1) and valve body (5) at pressure reduction.The effect of shoulder block (4) is the stroke of restriction spool (14).Valve gap (9) can be fixed on the core bar (10) by nut (11).
The state of spool (14) (open or close) depends on power that acts on valve disc (1) and the size that acts on the power on the valve gap (9).The size of power then depends on the size of pressure and axial useful area.In order to make the one-way valve air inlet laborsaving, the utility model is got bigger valve disc area.With pressurized air is example, when outside pressure (source of compressed air) is the about 5kg/cm of 0.5MPa(
2), the setting pressure of inboard (gas holder) is about 4.2 kg/cm of 0.42MPa(
2) time, the ratio of desirable valve disc area and valve gap area is between 1～1.5.Present embodiment gets 1.5, inflationtime shortened to originally (using common one-way valve) 1/3rd.
The utility model can be made different sizes with different materials, to be applicable to the requirement of different flows, pressure and medium. Above embodiment is take air as medium, and the utility model also can be used for other media in principle, comprises gas and liquid.
