Abstract
The utility model relates to a rotary stop valve, mainly by the left valve body and the valve body that right valve body fixed connection formed, valve gap, valve rod and hand wheel etc. constitute, its characterized in that installs the valve gap on the last flange face of left valve body, install the data plate on the valve gap, the center of valve gap is the valve rod, conical gear is equipped with to the lower extreme of valve rod, the top of valve rod is hand wheel and sign, the seal receptacle is fixed in the inner chamber recess of left valve body, the epaxial with the seal receptacle's end plane that contacts of seal receptacle is installed in seal receptacle central authorities to the seal receptacle, all there is trisection evenly distributed's hole groove on seal receptacle and the sealed terminal surface of covering, the cap nut is installed epaxially, the rack is installed on the terminal surface. The stop valve can be fully opened or fully closed by only rotating one sixth of the hand wheel, and has short operation time, simplicity and convenience.
Description
The utility model relates to the industrial ducted valve that is used for, and is specifically to be used for low pressure, the ducted a kind of rotary stop valve of pressure.
Existing old-fashioned stop valve, handwheel will rotate a few, just can make valve rod drive flap and rise and decline, reaches the standard-sized sheet of valve or the purpose of full cut-off.Complex structure is when useless and inconvenient operation.
The purpose of this utility model is to provide a kind of operating time short, as long as rotate the sixth circle of handwheel, just can make valve reach the rotary stop valve of standard-sized sheet or full cut-off.
The purpose of this utility model is achieved in that the rotary stop valve that a kind of valve body, valve gap, valve rod and handwheel etc. that are formed by fixedly connecting by left valve barrel and right valve barrel constitute, and it is characterized in that by left valve barrel, and valve gap is installed on the upper flange surface of left valve barrel; Nameplate is installed on the valve gap, the center of valve gap is a valve rod, and cone gear is equipped with in the lower end of valve rod, and the top of valve rod is handwheel and direction board, sealing seat is fixed in the lumen channels of left valve barrel, and the axle that sealing cover is installed in sealing seat central authorities upward contacts with the Transverse plane of sealing seat; The equally distributed hole slot of trisection is all arranged on sealing seat and the sealing cover end face, and acorn nut is installed on the axle, and tooth bar is installed on the end face of sealing cover, tooth bar and cone gear engagement; Described axle upper end is threaded.During work, by rotation hand wheel, the drive valve rod, the rotation of cone gear, thus drive tooth bar, the rotation of sealing cover, sealing cover produces relative rotation with the sealing seat that is fixed on the left valve barrel, makes pipeline realize connecting, and blocks or partly block the circulation of medium.
Because the utility model mainly is provided with sealing seat and sealing cover on its structure, and on its end face, be equipped with the equally distributed hole slot of trisection, so the rotation hand wheel sixth can realize that the unlatching of valve is with closed, reach the purpose of quick keying, make pipeline realize rapidly connecting, block or partly block the circulation of medium.The utility model is simple in structure, easy to operate, sealing is reliable.
Fig. 1 is the structure sectional view of the rotary stop valve of the utility model.
With reference to accompanying drawing as can be known, the valve body that the utility model is formed by fixedly connecting by left valve barrel (1) and right valve barrel (4), valve gap (6), valve rod (7) and handwheel formations such as (9), it is characterized in that by left valve barrel (1), valve gap (6) is installed on the upper flange surface of left valve barrel (1), nameplate (10) is installed on the valve gap (6); The center of valve gap (6) is valve rod (7); Cone gear (5) is equipped with in the lower end of valve rod (7), and the top of valve rod (7) is handwheel (9) and direction board (8), and sealing seat (2) is fixed in the lumen channels of left valve barrel (1); The axle (13) that sealing cover (3) is installed in sealing seat (2) central authorities upward contacts with the Transverse plane of sealing seat (2), on sealing seat (2) and sealing cover (3) end face the equally distributed hole slot of trisection is arranged all, acorn nut (12) is installed on the axle (13), tooth bar (11) is installed on the end face of sealing cover (3), tooth bar (11) and cone gear (5) engagement; Described axle (13) upper end is threaded.During work, by rotation hand wheel (9), drive valve rod (7), the rotation of cone gear (5), thereby drive tooth bar (11), the rotation of sealing cover (3), sealing cover (3) produces relative rotation with the sealing seat (2) that is fixed on the left valve barrel (1), make pipeline realize connecting, block or partly block the mediation of medium.
Claims (2)
1, a kind of valve body that is formed by fixedly connecting by left valve barrel and right valve barrel, the rotary stop valve that valve gap, valve rod and handwheel etc. constitute is characterized in that by left valve barrel (1), and valve gap (6) is installed on the upper flange surface of left valve barrel (1); Nameplate (10) is installed on the valve gap (6); The center of valve gap (6) is valve rod (7), and cone gear (5) is equipped with in the lower end of valve rod (7); The top of valve rod (7) is handwheel (9) and direction board (8), and sealing seat (2) is fixed in the lumen channels of left valve barrel (1), and the axle (13) that sealing cover (3) is installed in sealing seat (2) central authorities upward contacts with the Transverse plane of sealing seat (2); On sealing seat (2) and sealing cover (3) end face the equally distributed hole slot of trisection is arranged all, acorn nut (12) is installed on the axle (13), and tooth bar (11) is installed on the end face of sealing cover (3), tooth bar (11) and cone gear (5) engagement.
2, rotary stop valve according to claim 1 is characterized in that the upper end of described axle (13) is threaded.
