Abstract
The utility model discloses a drawing rod type gate valve and comprises a valve body, a bonnet, a valve stem, a flashboard and a handwheel. Wherein a plurality of outward protruding rings are arranged on the valve stem, thereby a caulking groove is arranged between two adjacent outward protruding rings. The upper end of the outward protruding ring on the top is limited through a locking screw which is installed on the upper portion of the bonnet and the lower end of the outward protruding ring on the base is limited by a boss shoulder which is arranged in the bonnet. An O-shaped sealing ring is installed in the caulking groove and the end surface of the locking screw is provided with a groove or a circular hole. The utility model is simple in structure. The valve stem is loaded from the upper portion and can be extracted when a valve is closed, which play a latch and safety role. The leakage caused by the pull-off of sealing parts is not to be worried about. Because the locking screw on the valve stem is installed by a special wrench and the external portion needs to be opened by the special wrench, the sealing leakage and the drop-out of nuts caused by human factors are capable of being eliminated completely.
Description
Technical field
The utility model relates to valve, is specifically related to a kind of gate valve.
Background technique
Traditional gate valve product, as Fig. 1, in the sealing of its valve rod 5 no matter be that to adopt sealing bedding and padding or O shape cushion rubber 9 all be to adopt hexagonal gland nut 4 to be spun on to compress or lock valve rod 5 on the valve gap 2 usually, make the gate valve increase compress parts such as gasket ring, nut, not only wasted material but also increased cost, and use common spanner just to open it easily, also easily stolen and destroy, valve rod 5 is to install from valve gap 2 bottoms in addition, again handwheel is installed in valve stem tip, trouble relatively.
The model utility content
The purpose of this utility model is to provide a kind of designs simplification, easy for installation, good airproof performance, beautiful shape and can valve rod can be extracted out behind valve closing, and what have effect with lock takes out the rod-type gate valve.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rod-type gate valve of taking out, comprise valve body, valve gap, valve rod, flashboard, handwheel, valve rod is installed in the valve gap, the valve rod top links to each other with handwheel, stem lower portion is connected with flashboard, it is characterized in that: valve rod is provided with some outer bulge loops, thereby constitute caulking groove at two adjacent evagination interannulars, the outer bulge loop upper end of described the top is spacing by the locking nut that is installed in valve gap top, outer bulge loop lower end bottom is spacing by the shoulder of the boss in the valve gap, in the described caulking groove O-ring seals is installed.
As of the present utility model preferred, described outer bulge loop is set to three roads.
As improvement of the present utility model, the end face of described locking nut is provided with groove or circular hole, can be arranged on the upper-end surface, also can be arranged on the side end face, in order to the installation or removal locking nut.
As above-mentioned improved preferred, the end on the described locking nut and groove or circular hole be set to 2～6 roads.
After the utility model adopted technique scheme, its advantage was:
(1) cancelled hexagon gland nut and packing press ring on traditional gate valve rod, made that the profile of whole valve is more succinct, elegant in appearance.
(2) because the mounting type of valve rod is packed into from top, improving the sealability except valve rod is provided with the two pass O-ring seals, mainly is valve rod can be extracted out behind valve closing, plays safety effect with lock.
(3) needn't worry to cause leakage because of coming off of obturator; Because of the locking nut on the valve rod is installed with special-purpose wrench, the outside must just can be opened with special-purpose wrench, therefore, can get rid of the seal leakage and the nut that cause because of personal factor fully and lose.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is traditional gate valve structure schematic representation.
Fig. 2 is the utility model overall structure schematic representation.
Embodiment
As shown in Figure 2, be the utility model gate valve structure-improved, comprise valve body 1, valve gap 2, valve rod 5, flashboard 3, handwheel 8, O-ring seals 6, valve rod 5 is installed in the valve gap 2, valve rod 5 tops link to each other with handwheel 8, valve rod 5 bottoms are threaded with flashboard 3, bulge loop 31 outside three roads about valve rod 5 is provided with, bulge loop 51 forms two caulking grooves 52 outside three roads, caulking groove 52 is equipped with two O-ring seals 6, and outer bulge loop lower end bottom is installed in the boss shoulder 21 in the valve gap 2, is takeed on 21 spacing by boss, valve gap 2 upper end is provided with a locking nut 7 in the aperture, be used to limit outer bulge loop 51 topmost, thereby make valve rod 5 spacing between valve gap 2 and locking nut 7, the end face of locking nut 7 is provided with 2～6 road grooves 71, also can be circular hole, need install and open with special spanner.Valve rod 5 moves up and down thereby drive flashboard 3 by handwheel 8 rotations, opens the keying effect of valve.Handwheel clockwise rotates to cutting out in the present embodiment, is rotated counterclockwise to opening.
Claims (4)
1, a kind of rod-type gate valve of taking out, comprise valve body (1), valve gap (2), valve rod (5), flashboard (3), handwheel (8), valve rod (5) is installed in the valve gap (2), valve rod (5) top links to each other with handwheel (8), valve rod (5) bottom is connected with flashboard (3), it is characterized in that: valve rod (5) is provided with some outer bulge loops (51), thereby constitute caulking groove (52) at two adjacent evagination interannulars, the outer bulge loop upper end of described the top is spacing by the locking nut (7) that is installed in valve gap top, outer bulge loop lower end bottom is spacing by the shoulder of the boss in the valve gap (2) (21), and O-ring seals (6) is installed in the described caulking groove (52).
2, according to the described a kind of rod-type gate valve of taking out of claim 1, it is characterized in that: described outer bulge loop (51) is set to three roads.
