Abstract
The invention discloses an ultrahigh pressure one-way valve. The chamber of the one-way valve is provided with a liquid inlet channel, a liquid outlet channel, a steel ball, a straight bar, a piston and a closed air chamber, wherein the steel ball is arranged at the outlet of the liquid inlet channel, the piston is slidingly arranged inside the closed air chamber in a sealing mode, the straight bar slidingly extends out of the closed air chamber in a sealing mode, one end of the straight bar is connected with the piston and the other end of the straight bar is connected with the steel ball; the liquid outlet channel is arranged on a chamber wall between the steel ball and the closed air chamber; closed air chamber walls on both sides of the piston are provided with air holes. According to the ultrahigh pressure one way valve, the piston divides the closed air chamber into two chambers, so that precision control can be performed on pressure of the two chambers and further precision control of the amount of pressure of liquid entering into the value body can be controlled; the ultrahigh pressure one-way valve is simple in structure and convenient to use.
Description
Technical field
The present invention relates to mechanical valve technical field, especially a kind of ultrahigh pressure one-way valve.
Background technique
Existing ultrahigh pressure one-way valve, although powerful, corresponding construction complexity, complex operation, and cannot reach accurate control; The more important thing is easily and break down that 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 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 ultrahigh pressure one-way valve,: in the cavity of this one-way valve, be provided with into liquid passage, liquid outlet channel, steel ball, straight-bar, piston and closed air chamber, described in being located at, described steel ball enters liquid channel exit, described piston seal is located in described closed air chamber slidably, described closed air chamber is stretched out in described straight-bar sealing slidably, and one end is connected with described piston, and the other end is connected with described steel ball; Described liquid outlet channel is located on the cavity wall between described steel ball and described closed air chamber; On the described closed air chamber wall of described piston both sides, be equipped with pore.
Further, described closed air chamber is located at described steel ball 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: utilize piston that closed air chamber is divided into two chambers, can carry out accurate control to the pressure of these two chambers, thereby reach the accurate fluid pressure size that enters valve body of controlling; 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 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, straight-bar 7, piston 4 and closed air chamber, 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 closed air chamber, closed air chamber is divided into two independently chambers 5 and 6, described straight-bar 7 seals and stretches out slidably described closed air chamber, and one end is connected with described piston 4, and the other end is connected with described steel ball 3; Described liquid outlet channel 2 is located on the cavity wall between described steel ball 3 and described closed air chamber; On the described closed air chamber wall of described piston 4 both sides, be equipped with pore 51 and 61.Closed air chamber is located at described steel ball 3 tops, described in enter liquid passage 1 outlet and be located at described steel ball 3 belows.
Respectively chamber 5 and chamber 6 are inputted the gas of different pressures through pore 51 and pore 61, can be controlled steel ball 3 and be transfused to the fluid pressure of valve body, reach the accurate effect of controlling ultrahigh pressure one-way valve.
