Abstract
The invention discloses an adjustable ultrahigh pressure check valve; a liquid inlet channel, a liquid outlet channel, a steel ball, a piston, a spring and a plug valve are arranged in the cavity of the check valve, wherein the steel ball is arranged at the outlet of the liquid inlet channel; the piston is hermetically arranged in the cavity in a sliding manner, and one end of the piston is connected to the steel ball while the other end is connected to the plug valve through the spring; the plug valve is in threaded connection with the inner wall of the cavity. The adjustable ultrahigh pressure check valve utilizes the spring and the piston to jointly plug the liquid inlet channel, and only with pressure which exceeds a threshold value for causing deformation of the spring, the check valve can be opened; in addition, the elastic force of the spring is changed by the plug valve, so that the pressure, which enables the check valve to be communicated, of the liquid in the liquid inlet channel is also variable.
Description
Technical field
The present invention relates to mechanical valve technical field, especially a kind of adjustable super-high 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 adjustable super-high 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 adjustable super-high pressure one-way valve, in the cavity of this one-way valve, be provided with into liquid passage, liquid outlet channel, steel ball, piston, spring and cock, 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 is connected with described cock through described spring; Described cock with described cavity inner wall for being threaded.
Further, described in, entering liquid passage and described liquid outlet channel is 90 degree settings.
Further, described steel ball size enters the diameter of liquid passage described in being greater than.
Further, described piston outer wall is provided with multiple-sealed circle.
Compared with prior art, the present invention has the following advantages: utilize spring to stop up entering liquid passage in conjunction with piston, exceeding the pressure that causes spring deformation, one-way valve just can be opened; The elastic force that can change by cock in addition spring, makes the fluid pressure that enters liquid passage of one-way valve conducting also become variable.
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 adjustable super-high pressure one-way valve as shown in Figure 1, in the cavity of this valve body 7, be provided with into liquid passage 1, liquid outlet channel 2, steel ball 3, piston 4, spring 5 and cock 6, 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 is connected with described cock 6 through described spring 5; Described cock 6 with described cavity inner wall for being threaded.Wherein the diameter of steel ball 3 is greater than into liquid passage 1, can stop up the liquid entering.
Entering liquid passage 1 is 90 degree settings with described liquid outlet channel 2, facilitates piston 4 to drive steel ball 3 to entering liquid passage 1 just to stopping up; Cock 6 is regulated, can regulate and control the elastic force of spring 5, thereby can control the fluid pressure entering in valve body 7, only have the elastic force that is greater than spring 5 when pressure, could promote steel ball 3, flow out from liquid outlet channel 2; Circulation in the other direction cannot be carried out.
For guaranteeing the sealing of piston 4 in cavity, piston 4 outer walls are provided with multiple-sealed circle.
