Description
Technical field
The utility model relates to a kind of pipe switch valve technology field, especially for the large capacity coke oven gas pipe line air inflow control valve that switches coke-stove gas and de-carbon air.
Background technique
Existing coke-stove gas cock is mainly used on the medium and small coke oven gas pipe, be used to switch coke-stove gas and de-carbon air, tap structure is respectively equipped with the faucet body of suction port and air outlet by upper and lower and the cock core that is arranged in the faucet body is formed, be provided with the horizontal inner chamber of tapering that an end is big, an end is little in the faucet body, big end at horizontal inner chamber is arranged big end cap, adopts bolt and seal ring to be tightly connected between big end cap and the faucet body; Arrange little end cap at the small end of horizontal inner chamber, the periphery of little end cap is connected with faucet body by seal ring; Supporting shaft in the little end cap, fixedly connected with an end of cock core in the inner of transmission shaft, and the other end then stretches out in the faucet body outside.Remove handle in the connection of the outer end of transmission shaft, act on by outside driving mechanism and remove, make transmission shaft drive cock core and rotate last, thus the open and close of realization suction port and air outlet passage and gas flow control.In order to guarantee the sealability between cock core and the faucet body, pass through to regulate supported spring between the ladder table top of bolt at gland and transmission shaft in the outer end of transmission shaft, by regulating bolt, holddown spring makes the horizontal inner chamber of cock core in faucet body pull to small end.Because faucet body and cock core material adopt grey cast iron HT200, to making casing rigidity low, the seal lubrication condition is poor, in addition, it is big to regulate the operation moment of torsion, and the Installation and Debugging difficulty is big, can not realize the sealing purpose of design between cock core and the faucet body fully, working life is short.
The model utility content
The utility model purpose be to design a kind of moment of torsion little, be convenient to install, the reliable gas tap of sealability.
The utility model comprises faucet body, and the faucet body top is provided with suction port, the below is provided with the air outlet, is provided with the horizontal inner chamber of tapering in the faucet body, arranges cock core in horizontal inner chamber; Small end at horizontal inner chamber is provided with little end cap, and described little end cap and faucet body are tightly connected; Big end at horizontal inner chamber is arranged big end cap, and the periphery of big end cap is connected with faucet body by seal ring, bolt; Described big end cap is provided with mesopore, the mesopore internal thread connects a bearing support, described bearing support is provided with flanging, the pin-and-hole of uniform some and cock core parallel to an axis on flanging, at the outer side surface of big end cap the positioning pin hole of cooperation is set, between the positioning pin hole of the pin-and-hole of bearing support and big end cap, connects locating stud; Described bearing support is provided with axial hole, at this through hole internal fixation ball bearing is set, and connects the transmission shaft of lateral arrangement in ball bearing by dynamic seal, and the inner of described transmission shaft is connected with cock core is coaxial, and the outer end is arranged in the outside of big end cap.
When the sealing between needs adjustment cock core and the faucet body, extract locating stud in advance out, the rotatingshaft bearing, because above design, bearing support, ball bearing have been connected to form a whole double-action mechanism, change bearing support in big end covering position, also changed simultaneously the relative position relation of bearing support, ball bearing and transmission shaft, cock core and big end cap, so, when inwardly screwing bearing support, just cock core is pressed to the small end of inner chamber, reach the purpose that improves the sealing between cock core and the faucet body.Transmission shaft back and forth rotates when preventing operation, causes to rotate between bearing support and the big end cap and change sealing between cock core and the faucet body, and the utility model is located by locating stud between the positioning pin hole of the pin-and-hole of bearing support and big end cap.The utility model has changed the mode that available technology adopting " is drawn ", but the mode of employing " pressure " improves the sealing between cock core and the faucet body.The utility model is convenient to be installed, adjusts, and the operation moment of torsion is little, long service life.
Install for convenience, the utility model is provided with the annular stop step in the inner of bearing support, and an end of described ball bearing is arranged on the annular stop step, and the other end of ball bearing is provided with bearing cap, and described bearing cap is threaded in the bearing support.By this structure, with the ball bearing fixed limit and be fixed between annular stop step and the bearing cap.
Between bearing support and the bearing cap attachment screw is set.By the connective stability between attachment screw reinforcement bearing support and the bearing cap.
Between bearing cap and ball bearing, locking nut is set.By the integrity between locking nut reinforcement ball bearing, bearing support and the bearing cap.
