Specific embodiment
As shown in Figures 1 to 10, the lifting open-close type hydrant 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 and inner tube connected mode be connecteds for threaded connection, Rapid chuck, glue
Connect or flange connection 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 can be provided with a capping 10 to carry out the closing of inner spout, it is to avoid debris enter.
Said inner tube 6 is moved in outer tube 3, and the upper end of outer tube 3 is provided with gland 2, for carrying out between inner tube 6 and outer tube 3
Sealing.
Further, sealing ring 9 is provided between the outer tube 3 and gland 2, the sealing ring 9 is contacted with inner tube 6, is used 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 provided with valve boss 5, and valve boss 5 is disposably overall with collet
It is made, is both a part for collet, is again the part of valve；The bottom of said inner tube 6 is provided with valve composite members 8, the valve
Composite members 8 are moved up and down so as to contact or depart from valve boss 5 with inner tube 6, are combined by valve boss 5 and valve
The switch of valve is realized in the clutch of part 8, so as to the on-off switch for realizing fluid is controlled.
The valve boss is preferably taper, or cylindricality, spherical etc., meets valve boss and is contacted with valve composite members
Realize sealing effectiveness.
A kind of optimization design, is provided with inner tube connector 7, said inner tube connector 7 between inner tube 6 and valve composite members 8
Including connector 702, the inwall of the connector 702 is provided with internal thread 701, the valve on the internal thread 701 and valve composite members 8
Screw thread 805 is engaged outdoors, and spacing ring 703 is provided with connector 702, for carrying out positioning of the inner tube on connector.
The valve composite members 8 include seal 801, are contacted with valve boss 5 by seal 801, left so as to real
Existing fluid on-off effect.
The seal is made up of thermoplastic elastomer (TPE).The thermoplastic elastomer (TPE) is different from rubber, is special industry
Industry term, is in industry widely used, not excessive with work to introduce.
The valve composite members 8 also include valve body 802, and the bottom of the valve body 802 is preferably broadening formation, or
Circular platform type or cylindricality, valve body 802 are provided with valve external screw thread 805, and through hole 804 is additionally provided with valve body 802, around valve body
Circumferential array has some prerotation vanes 803, and the seal is combined and is wrapped in valve body inner side and outside and by valve body
Inside and outside through hole connection seal.
As shown in Figures 4 and 5, the outer tube includes outer tube wall 301, is provided with the upside of outer tube wall to coordinate with gland 2

The guide plate 304 of pipe horizontal direction movement, the guide plate 304 is engaged with prerotation vane 803.
The seal 801 and valve body 802 of composition valve composite members 8 tend to integrative-structure through compound, and integral production does not have
Other assemblies, good integrity, with good stability in use.
Valve composite members 8 also need the technical requirements for meeting in addition to other required physical characteristics, and one is had compared with high-impact
Hit intensity, two is have certain elasticity, with ensure combine face closure it is tight, from thermoplastic elastomer (TPE) be compounded in ABS plastic or
On PC plastic members.Valve body 802 is first passed through into mould and injection machine injection molded using ABS plastic part or PC working of plastics, so
It is put into afterwards in the mould for making final composite members, because valve body 802 is different from the material of seal 801, therefore fusing point is different.Through
Injection machine is heated to thermoplastic elastomer (TPE), cooling, and then is combined into one.
The valve composite members 8 of interior bottom of the tube, used as the water stream channel of inner tube, support when both having played inner tube lifting carriage is made
With being again the switch mouthful door of valve；Valve composite members 8 are by hard resin material and thermoplastic elastomer (TPE) elastomeric material by system
One is compounded to form 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
Threaded connection.
During feedwater, under press elbow, under effect of water pressure, the seal in valve composite members passively coincide with valve boss
Closing, pressure is bigger, closes tighter；Elbow is above carried, the seal in valve composite members is separated with valve boss, valve is opened
Open.
The hydrant can be arranged in a protection well, it is not necessary to pressed to when using in well, the protection well includes having
The protection vertical shaft and a cover plate of some strength, the protection vertical shaft are embedded in below ground, and external force can be done directly on cover plate and protection
Well, it is to avoid the destruction of hydrant, to safeguard or providing space using hydrant.
In addition to the technical characteristic described in specification, the known technology of those skilled in the art is.
