Described connecting rod 6 includes the mobile jib portion 12 of lengthwise and the pressure section 13 being connected with mobile jib portion 12.
Described lower valve body 2 lower end is provided with support base 14, the valve rod 15 of insertion support base 14, the valve element 16 being arranged on valve rod 15 and is set on valve rod 15 and is located at the elastomeric element 17 of valve element 16 lower section.
Described support base 14 becomes round table-like, and it includes installation portion 18, the supporting part 19 for valve rod 15 insertion and some flanks 20 connecting installation portion 18 and supporting part 19 being fixedly mounted in lower valve body 2.Described installation portion 18 is bolted in lower valve body 2, installation easy to disassemble.Described supporting part 19 is circular hole.
Described valve rod 15 one end is inserted on the supporting part 19 of support base 14.The other end of described valve rod 15 is convexly equipped with the limit base 21 of annular.The cross section of described valve rod 15 is crosswise.Described valve element 16 is set on the other end of valve rod 15 and is located above limit base 21.
Described elastomeric element 17 is located between limit base 21 and the supporting part 19 of support base 14.The elastomeric element 17 of the present invention adopts spring, is valve element 16 and valve rod 15 offer floating power.
Described valve element 16 and valve port 3 and valve rod 15 all seal cooperation.The pressure section 13 of described connecting rod 6 can be resisted against on valve rod 15 and valve element 16 and drive their in the vertical directions to move back and forth.Described valve element 16 is included primary sealing area 22 that is being coordinated with valve port 3 sealing and becoming arc-shaped and seals coordinating with limit base 21 and become plane secondary sealing area 23.Described valve element 16 is additionally provided with the installing hole passing through for valve rod 15（Not shown）And it is looped around the compressing hole 24 of installing hole surrounding.Compressing hole 24 can increase the elasticity of valve element 16, and valve element 16 is subject to the effect of hydraulic pressure that elastic deformation occurs, and then increases the sealing property of valve element 16.
Described upper valve body 1 is provided with sluicing part near the position of valve port 3.The pressure section 13 of described connecting rod 6 and the cooperation of sluicing part.Described sluicing part includes the spilled water hole 27 of the mounting framework 25 being fixedly mounted on upper valve body 1, the caulking gum 26 being connected on mounting framework 25 and sealing with pressure section 13 cooperation and insertion caulking gum 26 and mounting framework 25.Described spilled water hole 27 connects the inside and outside of upper valve body 1.What described pressure section 13 included contacting with valve element 16 and valve rod 15 first compresses face 28 and compresses the relative upper surface in face 28 29 with first and be connected first and compress face 28 and the second of upper surface 29 and compress face 30.Described first compresses the arc-shaped that the primary sealing area 22 with valve element 16 for 28 one-tenth of the face matches.Described second compresses the distance of face 30 and upper valve body 1 inwall being progressively incremented by from top to bottom.Described second compresses face 30 can seal cooperation with caulking gum 26.Described spilled water hole 27 is always positioned at the lower section of upper surface 29.When valve element 16 and valve port 3 sealing cooperation, pressure section 13 is separated with the caulking gum 26 of sluicing part；When valve element 16 is departed from valve port 3, pressure section 13 is coordinated with caulking gum 26 sealing.Sluicing part, when valve element is closed, can exclude the hydrops within key, and when preventing temperature low, hydrops freeze, the work of impact turncock.
Described upper valve body 1 includes the nozzle 31 protruding out formation from both sides, the blind cover 32 being arranged on nozzle 31, the gland 33 being set in blind cover 32 and being fixed on nozzle 31, is set in blind cover 32 and is located at the snap ring 34 between gland 33 and nozzle 31 and is set in blind cover 32 and is fixed on the slotting ring 35 on gland 33.Described snap ring 34, after blind cover 32 is pulled down, can be used to connect snap joint, convenient and swift.
The operation principle of the turncock of the present invention is as follows：When starting turncock, as long as rotary motion handle 5, turning handle 5 drivening rod 6 moves downward, and connecting rod 6 first promotes valve rod 15 to move downward, and the limit base 21 of valve rod 15 departs from the secondary sealing area 23 of valve element 16, the first stress of valve rod 15, and moment of torsion is light, and one hand is operable；Then connecting rod 6 continues to move downward, and the pressure section 13 of connecting rod 6 promotes valve element 16 to move downward, and the primary sealing area 22 of valve element 16 departs from valve port 3, and the sealing due to valve rod 15 and valve element was first lost efficacy, and pressure release in key is just conducive to valve element 16 to depart from valve port 3；Now the second of pressure section 13 compresses the caulking gum 26 sealing cooperation in face 30 and sluicing part, prevents the water in key from leaking.
When closing turncock, reversion turning handle 5, connecting rod 6 moves upwards and departs from valve element 16 and valve rod 15, valve rod 15 Rapid reset under the counteracting force of elastomeric element 17 first, then valve rod 15 carries movable valve plug 16 Rapid reset again, last valve element 16 and valve port 3 and valve rod 15 all seal cooperation, and the turncock of the present invention is closed fast；Now the second of pressure section 13 is compressed face 30 and is departed from the caulking gum 26 of sluicing part, and sluicing part starts draining, prevents from existing hydrops in the key of turncock, the work of icing effect turncock when temperature is low.
In sum, these are only presently preferred embodiments of the present invention, the scope of the present invention should not be limited with this.I.e. every simple equivalence changes made according to claims of the present invention and description and modification, all should still remain within the scope of the patent.
