Abstract

The invention discloses an air-operated ultrahigh-pressure one-way valve. A liquid inlet channel, a liquid outlet channel, a steel ball, a piston and a high-pressure air chamber are arranged in the cavity of the one-way valve, wherein the steel ball is arranged on the outlet of the liquid inlet channel, the piston is arranged in the cavity in a sealing and sliding mode, one end of the piston is connected with the steel ball, the other end of the piston makes contact with the high-pressure air chamber, and the liquid outlet channel is formed in the portion, between the steel ball and the piston, of the wall of the cavity. According to the air-operated ultrahigh-pressure one-way valve, the piston and the airtight high-pressure air chamber are combined to control the pressure of liquid entering a valve body; only when the pressure of the input liquid is higher than that of the high-pressure air chamber, can the liquid jack up the steel ball and compress air and can the valve body be communicated. The air-operated ultrahigh-pressure one-way valve is simple in structure and convenient to use.

Description

Gas control ultrahigh pressure one-way valve
Technical field
The present invention relates to mechanical valve technical field, especially a kind of gas control ultrahigh pressure one-way valve.
Background technique
Existing ultrahigh pressure one-way valve, although powerful, corresponding construction complexity, complex operation, the more important thing is easily and breaks down, inconvenient maintenance causes cost high.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of gas control ultrahigh pressure one-way valve, structure is ingenious, easy to use.
In order to realize foregoing invention object, the invention provides following technological scheme: a kind of gas control ultrahigh pressure one-way valve, in the cavity of this one-way valve, be provided with into liquid passage, liquid outlet channel, steel ball, piston and plenum chamber, described in being located at, described steel ball enters liquid channel exit, described piston seal is located in described cavity slidably, one end is connected with described steel ball, and the other end contacts with described plenum chamber; Described liquid outlet channel is located on the cavity wall between described steel ball and described piston.
Further, described high pressure air locular wall is provided with pressure measurement or injecting hole.
Further, described plenum chamber is located at described piston top, described in enter liquid channel outlet and be located at described steel ball below.
Compared with prior art, the present invention has the following advantages: in conjunction with piston and airtight plenum chamber, control the fluid pressure size that enters valve body, and while only having input liquid pressure to be greater than plenum chamber pressure, ability jack-up steel ball pressurized gas, the conducting of valve body ability; Simple in structure, easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of gas control ultrahigh pressure one-way valve as shown in Figure 1, in the cavity of this one-way valve, be provided with into liquid passage 1, liquid outlet channel 2, steel ball 3, piston 4 and plenum chamber 5, described in being located at, described steel ball 3 enters liquid passage 1 outlet port, described piston 4 seals and is located at slidably in described cavity, one end is connected with described steel ball 3, and the other end contacts with described plenum chamber 5; Described liquid outlet channel 2 is located on the cavity wall between described steel ball 3 and described piston 4.Wherein, described plenum chamber 5 is located at described piston 4 tops, described enter liquid passage 1 outlet be located at described steel ball 3 belows, piston 4 and steel ball 3 are under the effect of plenum chamber 5, clogging enter liquid passage 1 export, only, in the time that the fluid pressure of input is greater than the pressure of plenum chamber 5, ability jack-up steel ball 3, enters in liquid outlet channel 2.
On the wall of plenum chamber 5, be provided with pressure measurement or injecting hole 6, can calculate fluid pressure by the pressure of measuring plenum chamber 5, or the pressure of change plenum chamber 5 adapts to needed fluid pressure.
