Secondary structure design has directive significance, so as to improve the sealing property and reliability of valve.
Stop valve（stop valve,Globe Valve）Opening and closing element be stopper flap, sealing above be in plane or sea
The conical surface, flap is for linear motion along the center line of valve seat.The forms of motion of valve rod,（Adopted name：Dark bar）, also there is lifting rotation
Rod-type can be used to control empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium etc. each
The flowing of type fluid.Therefore, such stop valve valve that dams is highly suitable as cutting off or adjusting and throttle
With.Due to the valve rod of such valve, to be turned on and off stroke relatively short, and with very reliable cutting function, and due to
The change of valve seat port and the stroke direct proportionality of flap, are very suitable for the regulation to flow.
At present, stop valve commercially in use, the attachment structure of its flap uses the mode of T-slot connection,
It is so operationally, upper with valve rod during using this connected mode, it usually needs cylindrical by flap cuts a part
OK, easily there is the phenomenon rocked and tangled by inclined hole on valve body in flap, and centering is nor very well, therefore can only be applicable
In the installation of horizontal pipe, and it is not applied for the installation of vertical pipe.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of centering is good, can be suitably used for horizontal vertical Pipe installing
Novel valve clack attachment structure stop valve.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of novel valve clack attachment structure stop valve,
Its innovative point is：Including
One valve body, has a runner for holding flow of media in valve body, while have respectively on valve body being communicated with runner
An inlet, a liquid outlet；
One opening/closing component, the opening/closing component includes that a valve rod being arranged in valve body, one are arranged on the valve of valve rod lower end
Valve and a valve seat in valve body, the sealing surface of the flap cooperate with the sealing surface of valve seat and are collectively forming sealing
Pair, is fixed between flap and valve rod by valve clack cover, and the flap is an overall cylindrical structure；
One filler unit, described filler unit includes being sleeved on the filler of valve rod outer end, is also sleeved on outside valve rod including one
The gland held and compressed to filler, described filler gland is mutually fixed by bolt with valve body.
Further, the connection between the flap and valve rod is specially：There is a spacing preiection in the lower end of valve rod,
The upper end of flap has the groove of a spacing preiection insertion for holding valve rod, after the groove on the lower end insertion flap of the valve rod is interior
Fixed by valve clack cover, the valve clack cover t shape, there is an external thread structure on the outer wall of valve clack cover, while recessed in flap
There is a female thread structure on the inwall of groove, fixation is locked by screw thread between the valve clack cover and flap.
The utility model has the advantage of：In the utility model, by the connection of flap by traditional T-slot connected mode
The form of valve clack cover mating connection is changed to, flap need not be so cut off so that flap is an overall cylindrical structure, with preferable
Centering, while being also not in the phenomenon that flap is tangled to inclined hole on valve body, it is adaptable to the installation of horizontal vertical pipeline.
For the connection between flap and valve rod, using valve clack cover fit system, convenient for assembly and dismounting.
