Abstract
The utility model relates to the field of a vacuum pump, in particular to an anti-overflow valve device of a vacuum pump. A carrier rod is arranged in the central holes of a valve body and a sealing seat, and a carrier rod sleeve, a ball-shaped bearing block and a sealing ball-shaped body are fixed on the carrier rod. The sealing seat and O-shaped sealing ring are arranged in the stopping opening of the upper end of the valve body, and the valve body is tightly fixed at an upper cover by a bolt. A floater is put in a floater cylinder body, and the floater cylinder body is connected with the valve body by screws. The inner surface of the sealing seat is a cone, and the outer surface of the sealing ball-shaped body is a cone. As the technical scheme is adopted, after a vacuum pump is operated and a tank body is filled with fecal sewage, the fecal sewage can not overflow and enter the outlet of an anti-overflow valve to be sucked into the vacuum pump, so the normal operation of the vacuum pump is ensured, and a whole pipeline system is protected well.
Description
Technical field
The utility model relates to field of vacuum, is a kind of anti-overflow valve device of vacuum pump.
Background technique
Usually the anti-overflow valve of vacuum pump is made up of parts such as valve body, sealing seat, push rod, top stem casing, sealing anchor plate, seal ring, float cylindrical shell, float, loam cakes.Push rod is packed in the central hole of valve body, sealing seat, top stem casing, sealing anchor plate, all is fixed on the push rod, and sealing seat is packed in the seam of valve body upper end, loam cake and valve body bolton.Float is put into the float cylindrical shell, and the float cylindrical shell is connected with screw with valve body.
In order to guarantee that the vacuum pump that special-purpose suction-type sewer scavenger disposes runs well, prevent that fecal sewage from sucking vacuum pump and damaging whole pipe-line system, when suction-type sewer scavenger installation pipeline system, anti-overflow device must be installed on tank body top.Because vacuum pump is when work, liquid level raises gradually in the tank body, the float cylindrical shell is immersed in the water liquid, float in the cylindrical shell also floats on the liquid level simultaneously, when the liquid level in the tank body continues to raise, float rises and will promote the push rod rise, in the circular groove of sealing anchor plate upper-end surface, O-ring seals is housed, the sealing anchor plate is fixed on the push rod, when float rose, O-ring seals contacted with the sealing seat end face, and the compresses seal end face plays the purpose of sealing, make fecal sewage not enter anti-overflow valve upper cover outlet place and suck vacuum pump, so that damage whole system.
This anti-overflow device deficiency is when the vacuum pump work, float raises with liquid level in the tank body and rises, when being drawn into the sewage ripples in the tank body and swung, or liquid level fails in time to close vacuum pump when reaching operational height, cause water liquid to continue to raise, having swung in the direct admission valve body cavity of sewage, sewage, residue thing just are immersed in valve body upper end endoporus and sealing anchor plate periphery.When float rising push rod rose, sealing anchor plate upper-end surface and sealing seat end face can produce not parallel, cause seal ring and sealing seat end face to can not get tight sealing, made fecal sewage enter the anti-overflow valve outlet port and sucked vacuum pump, damaged whole pipe-line system.
Summary of the invention
The purpose of this utility model is that a kind of new structure will be provided, and the vacuum pump anti-overflow valve that guarantees the suction-type sewer scavenger configuration is when work, and the ball sealer body closely contacts with the sealing seat inner conical surface, has reached tight sealing.
The purpose of this utility model is achieved in that push rod packs in the central hole of valve body, sealing seat, top stem casing, spheroid anchor plate, ball sealer body all are fixed on the push rod, sealing seat, O RunddichtringO are all packed in the seam of valve body upper end, valve body and loam cake bolton, float is put into the float cylindrical shell, the float cylindrical shell is connected with screw with valve body, and the internal surface of sealing seat is a cone, and the outer surface of ball sealer body is a cone.
Owing to adopted technique scheme, when the vacuum pump running, after fecal sewage was filled in the tank body, fecal sewage can not overflow and enter anti-overflow valve outlet port suction vacuum pump, has guaranteed the normal operation of vacuum pump, and whole pipe-line system has been obtained excellent protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings: 1, loam cake; 2, sealing seat; 3, O RunddichtringO; 4 push rods; 5, valve body; 6, float cylindrical shell; 7, float; 8, top stem casing; 9, spheroid anchor plate; 10, ball sealer body.
Embodiment
The utility model is further described below in conjunction with drawings and Examples.
In Fig. 1, push rod 4 is packed in the central hole of valve body 5, sealing seat 2, and top stem casing 8, spheroid anchor plate 9, ball sealer body 10 all are fixed on the push rod 4, and float 7 is put into float cylindrical shell 6, and float cylindrical shell 6 is connected with valve body 5 usefulness screws.Sealing seat 2, O RunddichtringO 3 are all packed in the seam of valve body 5 upper ends, and valve body 5 connects with loam cake 1 usefulness bolton.
When the vacuum pump work, liquid level raises gradually in the tank body, float cylindrical shell 6 is immersed in the water liquid, float 7 in the float cylindrical shell floats on the liquid level, when the liquid level in the tank body continued to raise, float 7 rose and promotes push rod 4 rises, and ball sealer body 10 just progresses into closely contact in sealing seat 2 cones, when fecal sewage reaches operational height in the tank body, stop the running of vacuum pump immediately.
