Eccentric hemisphere valve of lining fluorine high-risk medium, can detect the wearing and tearing condition of disk seat to in time discover the disk seat and damage, saved the maintenance time of disk seat greatly.

Description

Eccentric half ball valve of fluorine lining high-risk medium

Technical Field

The utility model relates to an eccentric hemisphere valve of line fluorine high-risk medium belongs to the special valve field of chemical industry high-risk medium pipeline.

Background

Enterprises in chemical industry, metallurgy, pharmacy need use strong corrosivity high-risk media such as liquid chlorine, hydrochloric acid, caustic soda in the production process of product, and when these high-risk media were carried through the pipeline, for the convenience of the control to high-risk media flow, need install multiunit special valve subassembly on the pipeline, and the eccentric hemisphere valve of line fluorine high-risk media is one of the special valves most commonly used.

Because the valve is used for controlling high-risk media, the requirement on the sealing property of the valve is high, and therefore soft sealing is adopted between the eccentric hemisphere and the valve seat. And because the soft seal has the defects of easy aging, easy abrasion, short service life and the like, the valve seat needs to be frequently inspected and maintained at irregular intervals, and the time is greatly wasted.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the fluorine-lined high-risk medium eccentric half ball valve can detect the abrasion condition of the valve seat.

Lining fluorine high-risk medium eccentric half ball valve, including valve body, disk seat, eccentric hemisphere, valve rod and executor, the bottom of valve body is equipped with the detection mouth of the inner chamber of intercommunication valve body, is equipped with the fluoroplastic lining layer on the inner wall of detection mouth, the end connection who detects the mouth has the test tube.

The detection tube is a transparent plastic tube.

The detection pipe is in threaded connection with the detection port.

Compared with the prior art, the utility model beneficial effect who has is:

eccentric hemisphere valve of lining fluorine high-risk medium, can detect the wearing and tearing condition of disk seat to in time discover the disk seat and damage, saved the maintenance time of disk seat greatly.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an enlarged view at a in fig. 1.

In the figure: 1. a valve body; 2. a valve seat; 3. an eccentric hemisphere; 4. a valve stem; 5. an actuator; 6. a detection tube; 7. a detection port; 8. a fluoroplastic lining layer.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in figure 1 and figure 2, lining fluorine high-risk medium eccentric half ball valve, including valve body 1, disk seat 2, eccentric hemisphere 3, valve rod 4 and executor 5, the bottom of valve body 1 is equipped with the detection mouth 7 of the inner chamber of intercommunication valve body 1, is equipped with fluoroplastic lining layer 8 on the inner wall of detection mouth 7, and the end connection who detects mouth 7 has a detecting tube 6.

In a preferred embodiment: the detection tube 6 is a transparent plastic tube; the detection tube 6 is in threaded connection with the detection port 7.

When the valve seat 2 is used, when the valve seat 2 is damaged and liquid leaks due to abrasion, leaked high-risk media enter the cavity of the valve body 1 and then enter the detection pipe 6 through the detection port 7. Therefore, when the maintainer finds that the detection pipe 6 is internally provided with high-risk media, the valve seat 2 is damaged, and the valve seat 2 needs to be replaced or maintained in time

Eccentric hemisphere valve of lining fluorine high-risk medium, can detect the wearing and tearing condition of disk seat 2 to in time discover disk seat 2 and damage, saved disk seat 2's maintenance time greatly.
