Abstract
The utility model discloses an integrated type oblique ball valve which comprises a valve body, a valve seat and a ball arranged in the valve body. The valve seat is fixedly connected with the valve body, and sealing rings are arranged among the ball, the valve seat and the valve body. The ball is tightly attached to the sealing face of the valve seat, an anti-static device is arranged between the ball and the valve body, a valve cover is arranged at the upper end of the valve body, a valve rod penetrates through the valve cover and is fixedly connected with the ball, the lower end of the valve rod is of a split spiral structure, and a disc spring is arranged between the upper end of the ball and the valve cover. The integrated type oblique ball valve has the advantages that more reliability is achieved due to the sealing face of a special structure, the sealing performance is good, moreover, when pressure in the valve body is abnormal, the valve rod can not disengage, the waterproof and anti-static effects are better, safety of a system is guaranteed, the hoisting capacity of the valve is small, and due to the split spiral structure arranged on the valve rod, the valve is more convenient to install and maintain.
Description
Technical field
The utility model relates to a kind of pipe technology, particularly the oblique ball valve of a kind of integrated type.
Background technique
Ball valve is applied more extensive, traditional ball valve in system of flow ducts, and sealability is inadequate, and valve inner structure is tight not, and waterproof antistatic performance is general, and safety coefficient is not high, maintenance service trouble.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of integrated type oblique ball valve.
To achieve these goals, the measure that the utility model is taked:
The oblique ball valve of a kind of integrated type, comprise valve body, valve seat and be located at the spheroid in valve body, described valve seat is fixedly connected with valve body, between spheroid and valve seat, valve body, be provided with seal ring, spheroid and sealing surface of seat fit tightly, the sealing surface of valve seat is wedge shape two inclined-planes, between described spheroid and valve body, be provided with anti-static device, the upper end of described valve body is provided with valve gap, valve rod is fixedly connected with spheroid through valve gap, the lower end of valve rod is split helix structure, between described spheroid upper end and valve gap, is provided with dish spring;
Between described valve gap and valve rod, be provided with filler, filler top is provided with Gland;
Described valve stem tip is fixedly connected with handle, between handle and valve rod, is provided with banking stop;
Described anti-static device is fireproof metal ring.
Valve interior wall is provided with for supporting the ledge structure of seal ring, and the inner seal ring of valve body can be placed on ledge structure like this, can reduce wear.
Valve body is provided with sandwich structure, has inculcated coolant in sandwich structure, can be useful in hot environment, and extraneous high temperature can not affect the medium in valve body.
The beneficial effects of the utility model: the sealing structure face of the utility model uniqueness is more reliable, sealability is better, and in valve body, press when abnormal, valve rod can not deviate from, waterproof anti-static effect is better, has guaranteed the safety of system, and valve opening and closing power is little, the split helix structure arranging on valve rod, makes the installation, maintenance of valve convenient.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model structure.
Embodiment
