Through adopting above-mentioned technical scheme, the inclination that the sealing that the rotation is located the downthehole is adjusted the sealing for the assembly error that the machining error that the compensation part produced and the disk seat assembly formed ensures that sealing and floater form good sealed, thereby promotes trap's leakproofness and life longer. When the valve is sealed in the use and goes wrong, the sealing part can be rotated to be adjusted, so that the sealing performance between the sealing part and the sealing part can be recovered, parts do not need to be replaced, the maintenance is also convenient, and the maintenance cost is greatly reduced.
Further setting the following steps: the pedestal part comprises a main body part and a dismounting part, the rotary hole is formed in the main body part and the dismounting part, a locking part is connected between the main body part and the dismounting part, when the dismounting part is separated from the main body part, the sealing part is separated from the rotary hole, and a sealing ring is arranged between the rotary hole and the sealing part.
Through adopting above-mentioned technical scheme, the cooperation between main part, dismantlement portion and the retaining member three realizes the dismantlement equipment in sealing and commentaries on classics hole, makes the installation operation of sealing more convenient and can change sealing, and simple structure, equipment change convenience.
Further setting the following steps: the valve body is provided with an installation cavity which is communicated with the inner cavity and the outside and used for installing the valve seat, the valve body is externally provided with a locking piece used for fixing the valve seat, and the locking piece is in threaded connection with the installation cavity.
Through adopting above-mentioned technical scheme, the setting up of locking piece realizes that the disk seat lies in the steady installation of installation cavity, ensures the steady operation of structure, when will maintaining or changing the disk seat, just can take out convenient operation from the installation cavity with the disk seat through the locking of relieving the locking piece.
Further setting the following steps: the valve cover is provided with a mounting frame extending into the inner cavity, and the mounting frame is provided with a filter screen.
Through adopting above-mentioned technical scheme, when will changing or wasing the filter screen, open the valve gap, can be together with taking out the filter screen from the inner chamber when opening the valve gap, the operation is more convenient, maintain simpler.
Further setting the following steps: an annular boss is formed in the inner cavity, when the valve cover seals the valve body, the mounting frame abuts against the boss to form sealing, and a sealing gasket is arranged between the mounting frame and the boss.
Through adopting above-mentioned technical scheme, sealed setting up of filling up guarantees the leakproofness between mounting bracket and the boss, makes the medium circulate after the filter screen filters completely to ensure filtration efficiency.
In conclusion, the utility model has the following beneficial effects: the utility model has better sealing performance, longer service life and lower maintenance cost.
