Description
Technical field
The present invention relates to and block flow element technical field, especially relate to a kind of ultrahigh pressure fluid-controlled cut-off valve.
Background technique
Stop valve, is also pipe valve, is most popular a kind of valve, is mainly used in blocking or connect various flowing medium.Stop valve product in the market generally adopts manual, electronic or pneumatic driving mode to open and close, and the general pressure of hand stop valve is higher, reaches as high as 100MPa, but its action need people on-site manual is implemented, therefore use has certain narrow limitation; And although electronic or pneumatic stopping valve can accomplish that Remote operates, owing to being subject to size, the Power Limitation of driving element, so its working pressure is general not high, be up to 40MPa.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides the ultra-high pressure stopped valve of a kind of hydraulic control.The present invention adopts the hard seal form of the metal conical surface and adopts hydraulic controlled operation to drive, and both can seal super high pressure fluid medium, and maximum pressure can reach more than 70MPa; Again because hydraulic driving power is large, therefore Remote operation can be realized.
Technological scheme of the present invention is as follows:
The ultra-high pressure stopped valve of a kind of hydraulic control, comprise valve gap and valve body, described valve gap and valve body are hollow cylinder, and described valve gap is connected with the bottom end seal of valve body, and the bottom of described valve gap is liquid inlet, and described valve body side has liquid outlet; The hollow space of described valve body is divided into two joints, and upper joint is columnar hollow, and lower joint is tapered hollow; Described liquid outlet is positioned at the intersection of joint and lower joint;
The hollow space of described valve body fills spool, and described spool is divided into two sections, and epimere is cylinder, is filled in the upper joint of valve body hollow space, by filling O type circle and back-up ring realizes dynamic seal (packing) between described spool epimere and valve body save;
The hypomere of described spool is vertebra shape, is filled in the lower joint of valve body hollow space, and described spool hypomere is positioned at liquid outlet bottom; Described spool hypomere is with the tapered hollow saved under conical surface seal valve body;
The top of the hollow space of described valve gap is connected with spool bottom by spring, and fastens by the elastic force of spring on the tapered hollow wall of the lower joint of valve body by the taper hypomere of spool;
Described valve body end sealing connects a piston cylinder, and described piston cylinder is hollow cylinder, and described piston cylinder top is hydraulic control oil-in; Described piston cylinder hollow space fills a piston; By filling O type circle and back-up ring realizes dynamic seal (packing) between described piston and piston cylinder; Described piston is connected with described spool top by nut.
Be connected by thread seal between valve gap with valve body, and seal at the joint O type circle of valve gap and valve body.Described piston cylinder is connected by thread seal with between valve body, and seals at the joint O type circle of piston cylinder and valve body.
The technique effect that the present invention is useful is:
This valve adopts metal conical surface seal form, and sealing effect is good, and IN mouth pressure more high sealing effect is better, sealing load can to more than 70MPa.And due to hydraulic driving power large, therefore Remote operation can be realized.Meanwhile, this valve adopts corrosion resistant titanium alloy material to be made, therefore may be used for sealing various high-pressure fluid medium, as seawater, fresh water and various industrial fluids medium, has market purposes widely.
Accompanying drawing explanation
Fig. 1 is the generalized section of the ultra-high pressure stopped valve of this hydraulic control.
Embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described.As shown in Figure 1, this stop valve comprises valve gap 1 and valve body 3 to the ultra-high pressure stopped valve arrangement of hydraulic control, and valve gap 1 and valve body 3 are hollow cylinder, and valve gap 1 is threaded connection with the bottom of valve body 3, and seals at the joint O type circle 14 of valve gap 1 and valve body 3.Valve body 3 side has liquid outlet Out, and the bottom of the hollow space of valve gap 1 is liquid inlet In.
The hollow space of valve body 3 is divided into two joints, and upper joint is columnar hollow, and lower joint is tapered hollow; Liquid outlet Out is positioned at the intersection of joint and lower joint.The hollow space of valve body 1 fills spool 5, and spool 5 is divided into two sections, and epimere is cylinder, is filled in the upper joint of valve body 3 hollow space, passes through to fill O type circle 11 and back-up ring 12 realizes dynamic seal (packing) between spool 5 epimere and valve body 3 saves.The hypomere of spool 5 is vertebra shape, is filled in the lower joint of valve body 3 hollow space, and the taper of spool 5 hypomere, with conical surface seal valve body 3 times joints, forms valve port 15; Valve port 15 is positioned at the bottom of liquid outlet Out.
The top of the hollow space of valve gap 1 is connected with spool 5 bottom by spring 2, and by the elastic force of spring 2, the taper hypomere of spool 5 is fastened on the lower pitch cone of valve body 3, make valve port 15 airtight, thus make valve gap 1 hollow space cannot with liquid outlet out UNICOM.
Valve body 3 end sealing connects a piston cylinder 4, and piston cylinder 4 is hollow cylinder, and hollow space fills a piston 6.The top of the hollow space of piston cylinder 4 is hydraulic control entrance P.Be threaded connection between piston cylinder 4 and valve body 3, and seal at the joint O type circle 13 of piston cylinder 4 and valve body 3.By filling O type circle 10 and back-up ring 9 realizes dynamic seal (packing) between piston 6 and piston cylinder 4; Piston 6 is connected with the top of spool 5 by nut 7.The connecting wall of nut 7 and piston 6 is arranged an O type circle 8 to seal.
Spool 5 and valve body 3 are two critical components of this valve, and adopt the metal conical surface firmly to seal between the two and carry out coordinating and formed " valve port 15 ", valve port 15 decides " unlatching " and " closedown " of this valve.The compressive force that the initial sealing power of valve port 15 is produced by spring 2 provides, and valve gap 1 is the supporting base of spring 2.
The working principle of this valve is as follows: In is the liquid inlet of this valve, and Out is liquid outlet, and P mouth is hydraulic control entrance.When In mouth has pressure fluid medium, the elastic force of this pressure and spring 2 acts on spool 5, makes the hypomere centrum of spool 5 upwards withstand the conical surface of valve body 3 times joint, valve port 15 is closed, In mouth and Out mouth obstructed.When P confession high pressure liquid force feed, overcome the precompression of In mouth pressure and spring 2 by hydraulic fluid pressure, promote spool 5 and move down, valve port 15 is opened, In with Out is communicated with, and realizes the unlatching of valve.After P oral fluid pressure is cancelled, spool 5 is return under the effect of In mouth pressure and spring 2 precompression, and valve 15 is closed again.
