Abstract
Two direction scale removal check valves relates to one kind and installs on sewer line, prevents the check valve of medium refluence. Damage scheduling problem design for solving the easy corrosion of current check valve valve rod and valve clack. Which comprises a valve body, the disk seat is fixed at the valve body anteriorly, there is the water inlet on the disk seat, the valve body has the delivery port, there is T shape sealing washer between valve clack and the disk seat, there is disk seat eccentric sleeve in the disk seat, there is the fixed plate in the valve body, gag lever post uide bushing and stem guide cover are all fixed on the fixed plate, there is the axle sleeve on the gag lever post uide bushing inner wall, establish eccentric sleeve in the stem guide cover, the front end of valve rod and gag lever post is all fixed on the valve clack, the valve rod passes through from the stem guide cover, the gag lever post passes through from the gag lever post uide bushing, the rear end of valve rod and gag lever post is all fixed on the locating plate, gag lever post uide bushing overcoat has the spring, spring one end top is on the fixed plate, other end top is on the valve clack, there is O shape sealing washer between disk seat and the valve body. The advantage can prevent that valve rod and valve clack corrosion from damaging.
Description
Technical field:
This utility model relates to one and is arranged on sewage conduct, it is prevented that the check-valves that medium flows backwards。
Background technology:
In use for some time, valve rod and flap easy-to-rust damage the existing check-valves being arranged on sewage conduct, make check-valves cannot normal operation, do not have the effect preventing medium from flowing backwards；Additionally flap and valve rod rotate under flow action, cause abrasion, reduce the service life of check-valves。
Summary of the invention:
Technical problem to be solved in the utility model is to provide one and has descaling function, double; two guiding scale removal check-valves of long service life。
Above-mentioned purpose is achieved in that it includes valve body, valve seat is fixed on valve body front portion, valve seat has water inlet, there is outlet at valve body rear portion, flap is contained in valve body, T-shaped sealing ring is had between flap and valve seat, valve seat excentric sleeve it is provided with in the valve seat in flap front, fixing plate it is fixed with in the valve body at flap rear, gag lever post fairlead and stem guiding set are all fixed on fixing plate, the two ends inwall of gag lever post fairlead is inlaid with axle sleeve all respectively that make with white steel, set, in stem guiding set, the excentric sleeve made with white steel, the front end of valve rod and gag lever post is all fixed on flap, valve rod passes through overlapping from stem guiding, gag lever post passes through from gag lever post fairlead, the rear end of valve rod and gag lever post is all fixed on location-plate, the spring that the useful white steel of gag lever post fairlead overcoat is made, spring one end withstands on fixing plate, the other end of spring withstands on flap, O-ring seals it is provided with between valve seat and valve body。
The utility model has the advantages that: owing to being provided with the excentric sleeve made with white steel at stem guiding in overlapping, valve seat excentric sleeve it is provided with in valve seat, after flap is opened, under flow action, flap produces vibration with valve rod, can shake by dirt impurity thereon, prevent corrosion from damaging, additionally, due to being provided with gag lever post fairlead and stem guiding set, so valve rod and gag lever post can be played guide effect, prevent flap from rotating, increase the service life of check-valves。
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model。
Detailed description of the invention:
With reference to accompanying drawing 1, it includes valve body 1, valve seat 2 is fixed on valve body front portion, valve seat has water inlet, there is outlet at valve body rear portion, flap 3 is contained in valve body, T-shaped sealing ring 4 is had between flap and valve seat, valve seat excentric sleeve 5 it is provided with in the valve seat in flap front, fixing plate 6 it is fixed with in the valve body at flap rear, gag lever post fairlead 7 and stem guiding set 8 are all fixed on fixing plate, the two ends inwall of gag lever post fairlead is inlaid with axle sleeve 9 all respectively that make with white steel, set, in stem guiding set, the excentric sleeve 10 made with white steel, the front end of valve rod 11 and gag lever post 12 is all fixed on flap 3, valve rod passes through overlapping from stem guiding, gag lever post passes through from gag lever post fairlead, the rear end of valve rod and gag lever post is all fixed on location-plate 13, the spring 14 that the useful white steel of gag lever post fairlead overcoat is made, spring one end withstands on fixing plate, the other end of spring withstands on flap, O-ring seals 15 it is provided with between valve seat and valve body。
