Abstract
The utility model relates to a high-pressure flexible-sealed spherical valve which comprises a valve body, a valve cover, a valve stem, a valve core and a handle. Two sides of the valve cover are connected with two ends of the valve body through screws, and the handle brings along the valve stem to drive the valve core. Sealant is filled in the connection part of the valve body and two sides of the valve cover. The utility model avoids the limitation of poor sealing effect of the prior art, that the cover of the common flexible-sealed spherical valve is connected with the valve body through screws, under high temperature and pressure working environment. The spherical valve keeps good sealing performance even under high temperature and pressure environment, in particular to the valve body without leakage. The utility has the advantages of simple structure, strong sealing performance, and long life-span.
Description
Affiliated technical field
The utility model relates to a kind of soft seal high-pressure ball valve.
Background technique
Traditional High-pressure Fire-proof Ball Valve that is applicable to high-pressure medium, its both sides valve gap and two ends of valve body are all by being threaded, and under the working environment of High Temperature High Pressure, the sealing effect that regular screw threads connect is relatively poor, thereby cause high-pressure ball valve to leak, have a strong impact on security of products energy and working life.
Summary of the invention
Be threaded in order to adopt between the valve gap that overcomes common soft seal high-pressure ball valve in the prior art and valve body, the relatively poor problem of working environment lower seal effect in High Temperature High Pressure, the utility model provides a kind of soft seal high-pressure ball valve, this soft seal high-pressure ball valve simple in structure, sealability is strong, reliability is high.
The technological scheme that its technical problem that solves the utility model adopts is: comprise valve body, valve gap, valve rod, ball core and handle, the both sides valve gap is threaded with two ends of valve body, handle drives valve rod drive ball core, at the filled sealer of the threaded joints of both sides valve gap and valve body.
The utility model is by above-mentioned specific design, makes ball valve still can keep can not leaking between good sealability, particularly valve gap and valve body under high-temperature high-pressure state, have simple in structure, sealability is strong, reliability is high, the advantage of long service life.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve gap 2, valve rod 3, ball core 4 and handle 5, and both sides valve gap 2 is threaded with the two ends of valve body 1, and handle 5 drives valve rod 3 drive ball cores 4, at both sides valve gap 2 and the filled sealer 6 of the threaded joints of valve body 1.When work, valve body 1 inside is in high-temperature high-pressure state, because sealer 6 has been reinforced thread seal, continues to guarantee the safe handling of remaining valid of soft seal high-pressure ball valve.
Claims (1)
1, a kind of soft seal high-pressure ball valve, comprise valve body, valve gap, valve rod, ball core and handle, the both sides valve gap is threaded with two ends of valve body, and handle drives valve rod drive ball core, it is characterized in that at both sides valve gap (2) and the filled sealer (6) of the threaded joints of valve body (1).
