Various valves such as the gate valve that uses on the present pipeline, stop valve, ball valve are born the effect that pipeline was blocked and regulated in its sealing.For preventing that other people from stealing and opening by mistake valve and causing the goods and materials in the pipeline to waste, employing is put various valves in the room or with the tubbiness object and is overlapped the method for sealing whole valve body usually, the antitheft cost height of this method, and anti-theft effect is poor.On the other hand, in present commercialization heat supply, water system, also press for a kind of valve that makes things convenient for locking, with control heat supply and water output.
The model utility content
For overcoming the above-mentioned defective that prior art exists, the purpose of this utility model provides the dark bar elastic sluice valve with wedge-shaped sealing face of a kind of locking formula, valve body or valve gap that employing is positioned at the valve rod side are provided with the locking closure that makes the valve rod locking, valve itself is just had prevent that other people from stealing and opening by mistake the effect of valve, and also have simple in structure, the advantage of the low and good anti-theft effect of antitheft cost.
The technological scheme that the utility model solution prior art deficiency is taked is: a kind of dark bar elastic sluice valve with wedge-shaped sealing face is characterized in that: be provided with the locking closure that makes the valve rod locking on the valve gap of gate valve rod side, this locking closure comprises:
One lockhole, described lockhole is positioned on the valve rod, and lockhole is corresponding with the locking bar position;
One locked groove, described locked groove are positioned on the valve gap of valve rod side, the locked groove one end valve rod that communicates, the other end corresponding valve gap exterior edge face that communicates, and the locked groove front end is provided with and the be spirally connected spiro union portion of precession of locking bar, and its rear portion is provided with the card post that blocks antitheft lock nut;
One locking bar, described locking bar is positioned at locked groove, and locking bar is a lead screw, and the locking bar rear end is a locking bar abnormity cylinder, and locking bar abnormity cylinder is provided with the magnet body;
One antitheft lock nut, described antitheft lock nut is positioned at locked groove and seals locked groove, and antitheft lock nut front portion is provided with draw-in groove and the draw-in groove open hole that crouches for card post card;
One key, described key one end is a cylinder, establishes the abnormity that is inserted on the locking bar abnormity cylinder in the cylinder and opens and closes groove, the key the other end is established key and is opened and closed the magnet body.
The beneficial effects of the utility model are: valve itself is just had prevent that other people from stealing and opening by mistake the effect of valve, and also have simple in structurely, antitheft cost is low, it only is one of percentage of setting up antitheft room cost, be 1/10th of other theft preventing method cost, good anti-theft effect, easy to use.On the other hand, the utility model also can effectively be controlled heat supply and water output in present commercialization heat supply, water system, to stop supplier's loss.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, the utility model mainly is to install locking closure additional on traditional valve, still adopt traditional valve mechanism, promptly at the affixed valve gap 18 in valve body 19 upper ends, be provided with valve rod 16 in the valve gap, be positioned at the outer valve rod in valve gap upper end and connect handle 17, the other end of valve rod is coupling and controls and is positioned at valve body and seals the valve plate 20 of opening its inner valve seat 21, handle with sleeve can drive valve rod switch valve plate, so repeat no more.
A kind of dark bar elastic sluice valve with wedge-shaped sealing face of the utility model is provided with the locking closure that makes the valve rod locking on the valve gap of gate valve rod side, this locking closure comprises:
One lockhole 15, described lockhole is positioned on the valve rod, and lockhole is corresponding with the locking bar position.Lockhole can penetrate for the locking bar front end, and when the locking bar front end penetrated in the lockhole, locking closure was in locking states, and valve rod can not rotate.Otherwise unlatching valve rod.Lockhole can be as required respectively valve rod go to valve plate close, crack, half-open during to standard-sized sheet, at the position of locking bar position correspondence several are set, for the locking of different conditions.
One locked groove 4, described locked groove are positioned on the valve gap of valve rod side, the locked groove one end valve rod that communicates, the other end corresponding valve gap exterior edge face that communicates, and the locked groove front end is provided with and the be spirally connected spiro union portion 1 of precession of locking bar, and its rear portion is provided with the card post 13 that blocks antitheft lock nut.
One locking bar 2, described locking bar is positioned at locked groove, and locking bar is a lead screw, and the locking bar rear end is a locking bar abnormity cylinder 14, and locking bar abnormity cylinder is provided with magnet body 3.Locking bar abnormity cylinder is that end section can be square, triangle or other polygonal behind the locking bar, removes key external application simple tool rotating rod lock, Open valve to prevent other people.The effect of magnet body is to hold antitheft lock nut internally, to prevent that other people from removing key external application hand or simple tool is opened antitheft lock nut.
One antitheft lock nut 11, described antitheft lock nut is positioned at locked groove and seals locked groove, and antitheft lock nut front portion is provided with draw-in groove 5 and the draw-in groove open hole 12 that crouches for card post card.Establish the hollow hole of putting into in the locking bar rear end 6 in the antitheft lock nut front end.The effect of antitheft lock nut is to prevent that other people from removing key external application hand or simple tool is opened locking bar.
One key 7, described key one end is a cylinder 8, establishes the abnormity that is inserted on the locking bar abnormity cylinder in the cylinder and opens and closes groove 10, the key the other end is established key and is opened and closed magnet body 9.
During use, when needing the locking valve rod, locking bar is placed in the locked groove, open and close groove with the abnormity on the key cylinder and be inserted in the rotation of locking bar Special-Shaped Column key handle drive locking bar, in the lockhole of locking bar on along the spiro union portion precession of locked groove to valve rod, blocking valve rod can not rotate, thus locking valve rod, i.e. Locking valve.Again key is taken in locked groove, in locked groove, be inserted in antitheft lock nut, the draw-in groove open hole aligning card post that is about to antitheft lock nut is put into locked groove, the card post was sitting in the draw-in groove after antitheft lock nut put in place, antitheft lock nut exterior edge face is parallel with corresponding valve gap face or be sunken into the valve gap face, get from antitheft lock nut except that aiming at Ka Zhuchu from the draw-in groove open hole, all the other all can not get from.At this moment, the magnet body on the locking bar abnormity cylinder holds antitheft lock nut internally, to prevent that other people from removing key external application hand or simple tool is opened antitheft lock nut, finishes Locking valve.When opening valve rod, key keying magnet body with the key the other end holds antitheft lock nut, rotate antitheft lock nut, make from draw-in groove open hole aligning Ka Zhuchu and get from antitheft lock nut, open and close groove with the abnormity on the key cylinder again and be inserted in locking bar Special-Shaped Column backward rotation key handle drive locking bar backward rotation, make in the lockhole on the locking bar end disengaging valve rod valve opening.
In a word, the utility model in use has and prevents that other people from stealing and opening by mistake the effect of valve, and also has simple in structurely, and antitheft cost is low, the effect that normal locking is convenient and practical rapidly.
