Abstract
The utility model discloses a choke valve, a perforated plate type throttle valve, including the choke valve main part, set up in that the choke valve main part is inside and the last valve plate that sealed coincide is in the same place valve rod, lower extreme and valve rod fixed connection's of valve plate, lower extreme and last valve plate fixed connection under and transmission shaft and first hand wheel, the choke valve main part has hollow barrel upwards extending with last valve plate just right position, the transmission shaft rotationally sealing connection in this barrel, the top facial height of transmission shaft is in the barrel and this top face up extends the linkage segment that has the minor diameter, and an end cover pierces into the top threaded connection of this linkage segment and barrel and in close contact with is located to the inside top surface of this end cover and the shaft shoulder of transmission shaft, the linkage segment top and the first hand wheel fixed connection of transmission shaft. The utility model discloses an end cover comes control and goes up the clearance between valve plate and the lower valve plate, has good leakproofness in the assurance between valve plate and the lower valve plate.
Description
Technical field
The utility model relates to a kind of choke valve, particularly a kind of hole plate type throttle valve.
Background technology
Choke valve is the critical component of choke manifold.Porose board-like choke valve in existing choke valve, its structure mainly includes throttle body, it is arranged on the upper valve plate within throttle body and lower valve plate, seal between valve plate and lower valve plate on this and be superimposed together, by rotating upper valve plate, the semicircle orifice on valve plate and lower valve plate is made to stagger certain angle to regulate flow.Due to effect and the inevitably abrasion of pressure, the gap between upper valve plate and lower valve plate can become larger, and sealing reduces.
Utility model content
For solving the deficiencies in the prior art, the utility model provides simple in construction and the hole plate type throttle valve of a kind of good airproof performance.
The utility model solves problem and the technical scheme is that
A kind of hole plate type throttle valve, including throttle body, it is arranged on throttle body inside and seals the upper valve plate and lower valve plate being superimposed together, the valve rod being connected is fixed, with upper valve plate, in lower end, the power transmission shaft being connected and the first handwheel are fixed in lower end with valve rod, described throttle body with upper valve plate just to position upwardly extend the cylinder of hollow, described power transmission shaft is sealedly connected in this cylinder rotationally, the top end face of described power transmission shaft is up extended with the linkage section of minor diameter higher than cylinder and this top end face, one end cap pierces into this linkage section and is connected with the screw top of cylinder and is in close contact at the inside top surface of this end cap and the shaft shoulder of power transmission shaft, the linkage section top of described power transmission shaft is fixing with the first handwheel to be connected.
As the further improvement of such scheme, between the inside top surface of described end cap and the shaft shoulder of power transmission shaft, it is additionally provided with ball.
As the further improvement of such scheme, it is connected for fine thread between described end cap and the top of cylinder.
The beneficial effects of the utility model: the utility model connects end cap in cylinder screw top, and the inside top surface of this end cap is pressed at the shaft shoulder of power transmission shaft, gap between upper valve plate and lower valve plate because of abrasion or pressure effect become big time, can directly turn end cap, the gap between valve plate and lower valve plate is made to reduce, ensureing sealing effectiveness between the two, compare traditional choke valve, its sealing is more preferably.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of innovation and creation is carried out clear, complete description, to be completely understood by the purpose of the invention, feature and effect.Each technical characteristic in the invention, can be with combination of interactions on the premise of the most conflicting conflict.
With reference to Fig. 1, a kind of hole plate type throttle valve, including throttle body 1, it is arranged on throttle body 1 inside and seals the upper valve plate 2 and lower valve plate 3 being superimposed together, lower end and the upper fixing valve rod 4 being connected of valve plate 2, the lower end power transmission shaft 5 that be connected fixing with valve rod 4 and the first handwheel 6, described throttle body 1 with upper valve plate 2 just to position upwardly extend the cylinder of hollow, described power transmission shaft 5 is sealedly connected in this cylinder rotationally, the top end face of described power transmission shaft 5 is up extended with the linkage section of minor diameter higher than cylinder and this top end face, here minor diameter refers to the diameter diameter less than power transmission shaft 5 itself of linkage section, both form the shaft shoulder at transition position.Other end lid 7 pierces into this linkage section and is connected with the screw top of cylinder and is in close contact at the inside top surface of this end cap 7 and the shaft shoulder of power transmission shaft 5, and the linkage section top of described power transmission shaft 5 is fixed with the first handwheel 6 and is connected.
Further improvement to embodiment, is additionally provided with ball 8 between the inside top surface of described end cap 7 and the shaft shoulder of power transmission shaft 5.Change the friction that ball 8 can be substantially reduced between end cap 7 and power transmission shaft 5.It is connected for fine thread between the most described end cap 7 and the top of cylinder.
The utility model compresses power transmission shaft 5 by using threaded end cap 7, and then control upper gap between valve plate 2 and lower valve plate 3, when sealing reduces because of abrasion or pressure effect for upper valve plate 2 and lower valve plate 3, rotatable end cap 7 reduces the gap between upper valve plate 2 and lower valve plate 3, it is ensured that its good sealing.
The above is the utility model preferably embodiment, and it is not intended that the restriction to the utility model protection domain, as long as realize the purpose of this utility model with essentially identical means all should belong to protection domain of the present utility model.
