Abstract
The utility model discloses a self-lockable valve which includes a valve body, a valve seat, a screw rod, a hand wheel, nuts, square keys, a press cap, a screw nut, and fillings. The valve body has a structure with changed inner/outer diameter. The lower end of the valve body is connected with the valve seat and the upper end is installed with the press cap. The screw rod passes through the valve body. Diameter of inner chamber of the valve body is changed. The fillings, a press ring, a press plate, a stabilizing block, a copper sleeve, the screw nut and a regulating cap press plate are sequentially arranged in the inner chamber of the valve body from bottom to top. An axial through-hole is arranged on the stabilizing block and is provided with a stabilizing nail, a spring and lead paste therein. An axial through-hole is arranged on the circumference of the lower part of the screw nut and is provided with a regulating rod and a regulating cap therein. The regulating cap press plate is installed at the top of the regulating cap. The utility model has the advantages of wide application, convenient operation, flexibility and theft-preventing function, and can be widely used in petroleum well and pipelines.
Description
One, technical field
The utility model relates to valve, particularly a kind of self-locked valve.
Two, background technique
The structure of traditional valve for freely opening or close, it also is anyone arbitrarily switch, but that this conventional valves exists is antitheft, the deadly defect of the non-constant of preventing destructing performance, especially in the open air, on the oil well or oil transport pipeline of border district, this valve is easier in any switch of lawless person, arbitrarily steal oil, also can suppress Lou, suppress bad valve because of arbitrarily closing sometimes stolen, oil leak accident take place, cause the loss of environmental pollution and national wealth.
Three, summary of the invention
The purpose of this utility model provides a kind of improved self-locked valve, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art, prevent any switch effectively, thereby stopped lawless person's stealing and destructive activity effectively, make state's family property wealth exempt from loss.
Self-locked valve described in the utility model, mainly comprise valve body, screw mandrel, valve plate, handwheel, nut, square key, pressure cap, mother lead screw and filler, described valve body is inside and outside variable-diameter structure, its lower end links to each other with valve body, the upper end is equipped with pressure cap, described leading screw passes valve body, in the valve body is diameter-changing cavity, be installed on filler in this chamber from bottom to top in turn, trim ring, pressing plate, steady piece, copper sheathing, mother lead screw and adjustment cap pressing plate, described steady piece is provided with axial hole, is equiped with steady nail in the hole, spring and plumbous mud, described mother lead screw lower circumference is provided with axial hole, be installed on regulating lever in the hole and adjust cap, this adjustment crown portion is installed on and adjusts the cap pressing plate.
Wherein, described mother lead screw is the up-small and down-big reducing cylindrical structure that has center hole, and top small diameter cylinders body internal thread is meshed with the leading screw outside thread, and the outside is provided with keyway, installs square key in the groove, and handwheel is installed on it.Axial distribution has at least one through hole on the large diameter cylinder of described mother lead screw bottom, is installed on regulating lever in this hole and adjusts cap.Described steady piece is the cylindrical structure that has the endoporus that can pass leading screw, and it axially is provided with at least one through hole, and this hole is communicated with the same footpath of the through hole on the mother lead screw, wherein be installed on steady nail and spring, under the effect of this spring, steady nail can insert in screw mandrel mother's the through hole, forms self-locking.Described valve body horizontal ends is installed on flange.Described valve body top is provided with internal thread and outside thread.Described steady piece is provided with outside thread, is meshed with the internal thread of valve body.Described copper sheathing is provided with outside thread and is meshed with the valve body internal thread, and mother lead screw and adjustment cap pressing plate are installed in the copper sheathing.Be equipped with on described mother lead screw and the adjustment cap and adjust the cap pressing plate.
The utility model has following advantage compared with prior art:
1, of many uses, not only can be used as the production valve, also can be used as the back pressure valve, both can on oil well head, use, also can on the multifunction storage oil tank, use, also can and use on the above valve of DN40 on various pipe networks such as water supply, air feed;
2, owing to adopted the self-locking structure, the switch degree of control valve is very easy to use, flexible arbitrarily;
3, have reliable anti-theft feature, make the unordered management that to defend of oil well and pipe network become orderly management.
