Abstract
The utility model discloses a prying type exhaust valve for preventing impurities from entering a valve cavity, wherein a valve seat is arranged above a shell, a floating ball is arranged in the shell, a sealing plug is tightly pressed on a valve port through a spring, a valve rod is arranged at the rear end of the sealing plug, the floating ball is connected with a rotating spring, the front end of the rotating spring enters the valve seat through a rotating spring sliding groove on the valve seat and is tightly attached to the lower part of the valve rod, the rear end of the valve seat is sealed by a gland, and a sealing device is arranged at the rear end of the valve seat to seal a hole formed between the rotating spring sliding groove and a rotating shaft of the rotating spring; the sealing device effectively seals the hole formed between the rotating shafts of the rotating springs, thereby thoroughly preventing impurities from entering the valve seat and solving the problems in the prior art.
Description
Technical Field
The utility model relates to an automatic exhaust valve.
Background
The prying type exhaust valve comprises a shell, a valve seat is mounted above the shell, a floating ball is arranged in the shell, a sealing plug is tightly pressed on a valve port through a spring, a valve rod is arranged at the rear end of the sealing plug, the floating ball is connected with a rotating spring, the front end of the rotating spring enters the valve seat through a sliding groove of the rotating spring on the valve seat and is tightly attached to the lower portion of the valve rod, and the rear end of the valve seat is sealed by a gland. When the water level drops and the floating ball sinks, the front end of the rotating spring moves upwards to pry the sealing plug for exhausting. The prying type exhaust valve has the main problems that a plurality of large holes are formed between the rotating shaft of the rotating spring and the sliding groove of the rotating spring, impurities easily enter the valve seat through the holes, and therefore the situation that the valve is not closed tightly and water leakage occurs is likely to happen.
Disclosure of Invention
The purpose of the utility model is to solve the existing problems, and to provide a prying-open type exhaust valve which can overcome the defects.
The utility model provides a prevent that impurity gets into sled formula discharge valve of valve pocket, which comprises a housin, the disk seat is installed to the casing top, there is the floater in the casing, the sealing plug compresses tightly on the valve port through the spring, the sealing plug rear end has a valve rod, the floater is connected and is changeed the spring, the front end of changeing the spring passes through the below that the spring cunning that rotates on the disk seat goes into in the disk seat and hugs closely the valve rod, the rear end of disk seat is sealed by the gland, its characterized in that sets up a sealing device at the rear end of disk seat and slides the hole that forms between the axis of rotation of going into the spring on the disk seat and rotating the spring and seal.
The sealing device effectively seals a hole formed between the rotating spring sliding groove on the valve seat and the rotating shaft of the rotating spring, thereby thoroughly preventing impurities from entering the valve seat and solving the problems in the prior art.

Legend: 1. the valve comprises a valve port, 2, a sealing plug, 3, a spring, 4, a filter screen, 5, a valve seat, 6, a valve rod, 7, a gland, 8, a rotating spring, 9, a floating ball, 10, a cap-shaped sealing ring, 11, a rotating spring sliding groove on the valve seat, 12, a hole between a rotating shaft of the rotating spring and the rotating spring sliding groove on the valve seat, 13, a rotating shaft of the rotating spring, 14, a shaft hole on the cap-shaped sealing ring, 15 and a mounting seam on the cap-shaped sealing ring.
Detailed Description
As shown in fig. 4, the sealing device is a cap-shaped sealing ring 10, two mounting slots 15 are symmetrically formed on the side surface of the cap-shaped sealing ring 10, a shaft hole 14 is formed at the rear part of each mounting slot, and the cap-shaped sealing ring is mounted on a rotating shaft 13 of a rotating spring, as shown in fig. 7. The rotating shaft 13 of the rotating spring slides into the valve seat 5 through the rotating spring on the valve seat 5 to bring the cap-shaped sealing ring 10 into the valve seat 5, the gland 7 is screwed tightly, and the cap-shaped sealing ring 10 is stably arranged at the rear part of the valve seat 5, as shown in figure 3. The cap-shaped sealing ring 10 seals the hole 12 between the rotating shaft of the rotating spring and the sliding groove of the rotating spring on the valve seat, and effectively prevents impurities from entering the valve seat 5.
