Abstract
The utility model discloses a kind of ball valves with fire proof construction, including valve body, valve deck and spool；The valve deck is connected on one end of the valve body, and the spool is mounted in the valve body；The fire collar made of refractory material is equipped in the valve deck or/and in the other end of the valve body, the fire collar is against on the sealing ring on the outside of the corresponding spool；Compressed spring is equipped between the fire collar and the valve deck or valve body.The ball valve has fire proof construction, and when a fire, ball valve will not leak, and use is safer.
Description
Technical field
The utility model is related to valve technology fields, more particularly to a kind of ball valve with fire proof construction.
Background technology
Ball valve is one of widely used valve, and operation principle is all by rotary spool as plug valve
Make valve opening and closing, but lighter than cock valve switching, relative volume is small, can make big-diameter ball valve.Ball valve sealing is reliable, knot
Structure is simple, easy to maintenance, and sealing surface, often in closed state, is not easy by medium erosion, thus in oil, chemical industry, metallurgy with sphere
Etc. industries be widely used.The ball valve of the prior art is usually that sealing ring is arranged between spool and valve body to reach the effect of sealing
Fruit, but when a fire is easy to be burned off and causes what leaking occurred in ball valve to show since sealing ring is nonmetallic materials
As.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of ball valve with fire proof construction, which has anti-
Fiery structure, when a fire, ball valve will not leak, and use is safer.
The technical solution of the utility model is to provide a kind of ball valve with fire proof construction having following structure,
Including valve body, valve deck and spool；The valve deck is connected on one end of the valve body, and the spool is mounted on described
In valve body；The fire collar made of refractory material is equipped in the valve deck or/and in the other end of the valve body, it is described
Fire collar is against on the sealing ring on the outside of the corresponding spool；Between the fire collar and the valve deck or valve body
Equipped with compressed spring.
After using the above structure, the ball valve with fire proof construction of the utility model has following compared with prior art
Advantage：
Due to being set in the valve deck of the ball valve with fire proof construction of the utility model or/and in the other end of the valve body
There are the fire collar made of refractory material, the fire collar to be against on the sealing ring on the outside of the corresponding spool；Institute
Compressed spring is equipped between the fire collar and the valve deck or valve body stated, in this way, when a fire, the sealing on the outside of spool
After circle is burned out, fire collar is just directly against on spool, plays the role of sealing, the phenomenon that from without leaking.
As an improvement, being equipped with fire collar in the valve deck.It is such to be designed as optimum implementation.
As an improvement, the inside of the valve deck is equipped with mounting groove, the fire collar is mounted in the mounting groove.
As an improvement, being sealed by the first sealing ring between the fire collar and mounting groove.
As an improvement, the fire collar is equipped with bulge loop, the mounting groove close to the outside of one end of the spool
One end corresponding with the bulge loop is equipped with concave ring, and the bulge loop coordinates in the concave ring, and the bulge loop is separate
The compressed spring is equipped between the side of the spool and the side wall of the concave ring.
As an improvement, being sealed by the second sealing ring between the bulge loop and the concave ring.
As an improvement, the fire collar is equipped with seal groove close to the end face of one end of the spool, it is described
Sealing ring on the outside of spool is stuck in the seal groove.
