Description

Fixed PE ball valve of ball

Technical Field

The utility model relates to a technical field of PE ball valve especially relates to a fixed PE ball valve of ball.

Background

The PE ball valve has the advantages of no corrosion, no external leakage of an integral valve body, aging resistance, long service life, direct burial, convenience in connection with a PE pipe network and the like, and is generally applied to town gas pipe networks, but with the increase of the caliber of the pipe network, the large-caliber PE ball valve generally has the problems of internal leakage and difficulty in opening.

Most ball valves in the market at present adopt a floating ball valve structure, along with the increase of the caliber and the operating pressure of a pipeline, the thrust of a medium to a ball body reaches more than several tons, and the pressure to a rubber valve seat far exceeds the allowable specific pressure of rubber, so that the valve seat fails and leaks. Meanwhile, the force arm is increased due to the fact that the ball deviates from the rotation center, and the opening torque is increased.

The ball valve that increases the locating pin below the ball appears in the market, and during the locating pin disect insertion PE valve body, because PE material intensity is low, easily take place the creep, can't bear the thrust of ball, the shaft hole of being of a specified duration is drawn greatly, and the ball is fixed to be inefficacy.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a through at spheroid bottom fastening cartridge locating pin to through locating pin and locating piece normal running fit, make the spheroid except rotating, no other actions again, the locating piece is installed in the middle of the valve body, the locating piece is big with valve body area of contact, can effectively bear the thrust of spheroid transmission, spheroidal fixed removal and the spheroid of reducing are to rubber valve seat sealing specific pressure, leak in the ball valve effectively and the problem of moment of torsion increase, improve the fixed PE ball valve of ball of stability in use.

The utility model discloses a fixed PE ball valve of ball, including valve body, locating piece, locating pin, metal insert and spheroid, the inside water cavity that leads to that is provided with of valve body, locating piece fixed mounting is in the inside bottom of valve body, locating piece middle part intercommunication is provided with the jack, install the metal insert on the jack lateral wall, the locating pin rotates the cartridge in the locating piece jack, spheroid middle part intercommunication is provided with the water hole, the spheroid bottom sets up to the plane, and locating pin fastening cartridge is at spheroid bottom middle part.

The utility model discloses a fixed PE ball valve of ball, the locating piece adopts POM, PA material preparation to form.

The utility model discloses a fixed PE ball valve of ball, metal insert fuses as an organic whole through injection molding process and locating piece.

Compared with the prior art, the beneficial effects of the utility model are that: through fastening cartridge locating pin in spheroid bottom to through locating pin and locating piece normal running fit, make the spheroid except rotating, no other actions again, the locating piece is installed in the middle of the valve body, and locating piece and valve body area of contact are big, can effectively bear the thrust of spheroid transmission, and spheroidal fixed removal and the spheroid of reducing are to the sealed specific pressure of rubber valve seat, have effectively solved the problem of leaking and the moment of torsion increase in the ball valve, improve stability in use.
