In figure:1 elbow, 2 glands, 3 outer tubes, 301 outer tube walls, 302 outer tube external screw threads, 303 flarings, 304 guide plates, 4 bottoms Support, 5 valve boss, 6 inner tubes, 7 inner tube connectors, 701 internal threads, 702 connectors, 703 spacing rings, 8 valve composite members, 801 Sealing element, 802 valve bodies, 803 guide pins, 804 through-holes, 805 valve external screw threads, 9 sealing rings, 10 cappings.

Specific implementation mode

As shown in Figures 1 to 10, which includes elbow 1, inner tube 6, outer tube 3, gland 2 and collet 4, Elbow 1 is connected with inner tube 6, more excellent design, and the elbow connect for threaded connection, Rapid chuck with inner tube connection type, is viscous Connect or flanged joint in one kind.

The elbow 1 may be configured as split-type structure with inner tube 6, as shown in Figure 8.Elbow 1 can screw off take away avoid by Steathily, and in inner tube 6 it can be equipped with a capping 10, to carry out the closing of inner spout, sundries is avoided to enter.

Said inner tube 6 moves in outer tube 3, and 3 upper end of outer tube is equipped with gland 2, for carrying out between inner tube 6 and outer tube 3 Sealing.

Further, sealing ring 9 is equipped between the outer tube 3 and gland 2, the sealing ring 9 is contacted with inner tube 6, to Carry out the sealing of inner tube and outer tube.

The sealing ring can be rubber ring or silica gel ring.

Outer tube 3 is connected with collet 4, and the collet is equipped with valve boss 5, and valve boss 5 is disposably whole with collet It is made, is both a part for collet and the component of valve;6 lower end of said inner tube is equipped with valve composite members 8, the valve Composite members 8 are moved up and down with inner tube 6 to contact or be detached from valve boss 5, compound by valve boss 5 and valve The switch of valve is realized in the clutch of part 8, to realize the on-off switch control of fluid.

The valve boss is preferably taper or cylindricality, spherical shape etc., meets valve boss and is contacted with valve composite members Realize sealing effect.

A kind of optimization design is equipped with inner tube connector 7, said inner tube connector 7 between inner tube 6 and valve composite members 8 Including connector 702,702 inner wall of the connector is equipped with internal thread 701, the internal thread 701 and the valve in valve composite members 8 Screw thread 805 matches outdoors, spacing ring 703 is equipped on connector 702, for carrying out positioning of the inner tube on connector.

The valve composite members 8 include sealing element 801, are contacted, are left to real with valve boss 5 by sealing element 801 Existing fluid on-off effect.

The sealing element is made of thermoplastic elastomer (TPE).The thermoplastic elastomer (TPE) is different from rubber, is that industry is special Industry term, is in industry widely used, and is not introduced excessively with work.

The valve composite members 8 further include valve body 802, and 802 lower part of the valve body is preferably broadening formation, or Circular platform type or cylindricality, valve body 802 are equipped with valve external screw thread 805, through-hole 804 are additionally provided in valve body 802, around valve body Circumferential array has several guide pins 803, and the sealing element is compound to be wrapped in valve body inside and outside and by valve body Through-hole connects inside and outside sealing element.

As shown in Figures 4 and 5, the outer tube includes outer tube wall 301, is equipped on the upside of outer tube wall to coordinate with gland 2 Outer tube external screw thread 302, flaring 303 is equipped on the downside of outer tube wall, the outer tube wall and flaring lower end inside are equipped in limiting The guide plate 304 of pipe horizontal direction movement, the guide plate 304 are matched with guide pin 803.

The sealing element 801 and valve body 802 of composition valve composite members 8 tend to integral structure through compound, and integral production does not have Other assemblies, good integrity have good stability in use.

Valve composite members 8 are in addition to other required physical characteristics, the technology requirement also needed to meet, first, with compared with high-impact Hit intensity, second is that there is certain elasticity, to ensure to combine face closure tight, select thermoplastic elastomer (TPE) be compounded in ABS plastic or On PC plastic component.First use ABS plastic part or PC plastic part by mold and injection molding machine injection molded valve body 802, so It is put into afterwards in the mold for making final composite members, because valve body 802 is different from the material of sealing element 801, therefore fusing point is different.Through Injection molding machine heats thermoplastic elastomer (TPE), cooling, and then is combined into one.

The valve composite members 8 of bottom of inner tube, as the water stream channel of inner tube, support when both having played inner tube lifting carriage is made With, and be the switch mouth door of valve;Valve composite members 8 pass through system by hard resin material and thermoplastic elastomer (TPE) elastomeric material It is compounded to form one as technique, realizes that controlled valve closes faying face with valve boss 5.Valve composite members 8 it is Nian Jie with inner tube or It is threadedly coupled.

When water supply, under press elbow, under effect of water pressure, the sealing element in valve composite members passively coincide with valve boss Closing, pressure is bigger, and closing is tighter;Elbow is above carried, so that the sealing element in valve composite members is detached with valve boss, valve is opened It opens.

The hydrant can be mounted in a protection well, be pressed in well when need not use, and the protection well includes having The protection vertical shaft and a cover board of some strength, the protection vertical shaft are embedded in below ground, and external force can be done directly on cover board and protection Well avoids the destruction of hydrant, to safeguard or providing space using hydrant.

It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
