Abstract
The utility model relates to a gate valve, comprising a valve body, a valve cap, a valve stem, a hand wheel, a compression nut and a shutter. The two ends of the valve stem are separately connected with the hand wheel and the shutter, a convex ring is arranged on the valve stem, a step is arranged on the inner cavity wall of the valve cap to divide the inner cavity of the valve cap into an upper and a lower cavities which are communicated, a cam is matched with the upper cavity of the valve cap, the lower valve stem of the convex ring is matched with the lower cavity of the valve cap, when locked, the valve stem, the compression nut and the hand wheel can be extracted together. The utility model has the advantages of simple structure, convenient assembly, and good locking effect. The utility model is an ideal stem extraction type gate valve.
Description
One, technical field
The utility model relates to a kind of valve.
Two, background technique
All valve must be installed on any pipeline, the kind of valve is a lot, the gate valve structure that is arranged on the intake pipe of water meter is simpler, it has valve body, valve gap, valve rod, flashboard, on the valve rod external part handwheel is housed, rotate handwheel and just can open or close gate valve, operation easily, but when needs carry out mandatory administration to pipeline, locking gate valve for example uses above-mentioned gate valve that can not lock construction then to be difficult to meet the demands, and is easy to because of handwheel rotates, even the dismounting handwheel adopts general utility tool also to be easy to open gate valve.
Three, summary of the invention
The purpose of this utility model is to provide a kind of convenient management, and what have the locking effect takes out the rod-type gate valve.
The utility model is a kind of rod-type gate valve of taking out, and comprises valve gap, valve body, valve rod, handwheel, flashboard, valve rod one end and handwheel is fastening links wherein, the valve rod the other end links by screw thread and flashboard activity, and big of valve rod and flashboard all are arranged in valve gap and the chamber that valve body is communicated with.Has step on the valve cover cavity wall, make valve gap can be divided into epicoele and the cavity of resorption that is communicated with up and down, has bulge loop on the valve rod, bulge loop matches with the valve gap epicoele, be equipped with gland nut on the valve rod on bulge loop top, gland nut and valve gap epicoele outside screw link, and the valve rod of bulge loop bottom matches with the valve gap cavity of resorption.Be embedded with 2-3 O-ring seals on the valve rod bulge loop.Other disposes a sealing nut that is complementary with the valve gap epicoele outside.
The utility model when needs locking flashboard, need only be closed flashboard after adopting said structure, unclamps gland nut, rotation hand wheel, and valve rod, gland nut and handwheel can be extracted out together at this moment, thereby flashboard can't be opened again.The effect of O-ring seals is to increase the sealing of gate valve when normally using at ordinary times, and the effect of sealing nut prevents that dust from entering in the valve body when being that Sluice valve lock closes.While the utility model assembling is also greatly convenient, need only inwardly assemble from the valve gap epicoele at valve gap assembling back valve rod, fixes getting final product again with gland nut and valve gap epicoele screw thread.
Four, description of drawings
Fig. 1 is the utility model overall structure schematic representation;
Fig. 2 extracts valve rod, gland nut and handle out for the utility model, the structural representation during the configuration sealing nut.
Five, embodiment
The utility model is a kind of rod-type gate valve of taking out, and comprises valve gap 1, valve body 8, valve rod 2, handwheel 5, flashboard 6, wherein valve rod 2 one ends and handwheel 5 fastening linking, valve rod 2 the other ends link by screw thread and flashboard 6 activities, and valve rod 2 big portions and flashboard 6 all are arranged in valve gap 1 and the chamber that valve body 8 is communicated with.Has step 1-1 on the valve gap 1 chamber wall, make valve gap 1 can be divided into epicoele 1-2 and the cavity of resorption 1-3 that is communicated with up and down, has bulge loop 2-1 on the valve rod 2, bulge loop 2-1 matches with valve gap epicoele 1-2, be equipped with gland nut 4 on the valve rod on bulge loop 2-1 top, gland nut 4 links with valve gap epicoele 1-2 outside screw, and the valve rod of bulge loop 2-1 bottom matches with valve gap cavity of resorption 1-3.Be embedded with 2-3 O-ring seals on the valve rod bulge loop 2-1.Other disposes a sealing nut 7 that is complementary with the valve gap epicoele 1-2 outside.
When the needs Locking valve, the handle 5 that turns clockwise closes flashboard 6 by valve rod 2 rotations, at this moment, unclamp gland nut 4, handwheel 5 again turns clockwise, valve rod 2, assemblies such as gland nut 4 and handwheel 5 can be extracted out together, revolve on valve gap 1 top and put sealing nut 7.
When needs were opened valve, the sealing nut 7 of dismantling was with valve rod 2, assemblies such as gland nut 4 and handwheel 5 screw in counterclockwise, and valve rod 2 links with flashboard 6 screw threads, gland nut 4 and valve gap 1 top also again screw thread link and put in place, another mistake hour hands rotation hand wheel 5, flashboard 6 can be opened.
