Abstract
The utility model discloses an adjustable valve rod of a track friction-free butterfly valve. A vertical guide through hole is arranged in the valve rod, a penetrating hole is arranged on a press cover right facing the guide through hole, a transverse screw pin respectively penetrates through the penetrating hole and the guide through hole, and two ends of the screw pin are respectively screwed with a locking nut. The valve rod and a press rod are reasonable in connection design, ensure reliability of rising opening of a valve clack and improve integral using performance of the butterfly valve.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to the adjustable valve rod that track does not have the friction butterfly valve.
Background technique
Track does not have the friction butterfly valve and structurally changed the movement locus that traditional butterfly valve opens and closes valve plate: during unlatching, dish version and valve body sealing surface elder generation front are left, and rotate dish version standard-sized sheet then; When closing, forward compressed after rotation dish version and valve body sealing surface aligned earlier.Sealing surface does not have wearing and tearing fully in whole switching process.But the valve rod of present valve and the design of gland mounting structure are unreasonable, and assembling and work are inconvenient.
The model utility content
The purpose of the utility model provides the adjustable valve rod that a kind of track does not have the friction butterfly valve, and valve rod is connected reasonable in design with depression bar, has guaranteed the reliability that flap rises and opens, and has improved the whole usability of butterfly valve.
The technological scheme of the utility model is following:
Track do not have the friction butterfly valve adjustable valve rod, have vertical guide through hole in the valve rod, with guide through hole over against gland on have perforation, have horizontal threaded to pass perforation, guide through hole respectively, the two ends of threaded are combined with locking nut respectively.
Be fixed with block respectively on the threaded of described valve rod both sides.
The valve rod of the utility model can lead mobile along threaded up and down, and valve rod is connected reasonable in design with depression bar, has guaranteed the reliability that flap rises and opens, and has improved the whole usability of butterfly valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; Track does not have the adjustable valve rod of friction butterfly valve; Have vertical guide through hole 2 in the valve rod 1, with guide through hole 2 over against gland 6 on have the perforation 3, have horizontal threaded 4 pass respectively the perforation 3, guide through hole 2; The two ends of threaded are combined with locking nut 5 respectively, are fixed with block respectively on the threaded of valve rod 1 both sides.
Claims (2)
1. track does not have the adjustable valve rod of friction butterfly valve; It is characterized in that: have vertical guide through hole in the valve rod; With guide through hole over against gland on have perforation, have horizontal threaded to pass perforation, guide through hole respectively, the two ends of threaded are combined with locking nut respectively.
2. track according to claim 1 does not have the adjustable valve rod of friction butterfly valve, it is characterized in that: be fixed with block respectively on the threaded of described valve rod both sides.
