Abstract
The utility model relates to a forcible sealing ball valve could be used in high temperature, low temperature or high pressure. The ball valve used for the moment are always has the problem of seepage in high temperature, low temperature or high oil path pressure owing to the washer. The utility model provides a metal sealing ring between valve seat and valve cover to solve the above problem. The utility model has the advantages of high temperature-resistance, low temperature-resistance, high pressure-resistance, wearing-resistance and good sealing performance.
Description
Technical field
The utility model relates to a kind of high temperature cryogenic high pressure hard seal ball valve, and it is applicable to the circulation of high pressure ultralow temperature liquid line and blocks.
Background technique
At present the hard seal ball valve ubiquity high temperature that uses down can not high pressure, and high pressure inconvenience down opens and closes, can not high vacuum under the low temperature etc. problem, let alone wear-resistant, thereby people wish to have a kind of ball valve appearance that can overcome above-mentioned shortcoming.
Summary of the invention
The purpose of this utility model is to provide a kind of high temperature cryogenic high pressure hard seal ball valve, and it has solved freely opening and closing and sealing problem of ball valve under high pressure, superhigh temperature, the ultra-low temperature surroundings.
The utility model is achieved through the following technical solutions, it comprises valve gap, valve body, supporting plate, metal o-ring, spring, spheroid, packing washer, valve seat, valve rod, Stuffing box, connects formations such as dish, worm gearing, and metal o-ring is arranged between valve seat and the valve gap.
The utlity model has characteristics such as high pressure resistant, low temperature resistant, wear-resistant, good airproof performance.
Description of drawings
Accompanying drawing is the utility model sectional structure schematic representation.
In the accompanying drawing, 1 is that valve gap, 2 is that valve body, 3 is that supporting plate, 4 is that metal o-ring, 5 is that spring, 6 is that spheroid, 7 is that packing washer, 8 is that valve seat, 9 is that valve rod, 10 is that Stuffing box, 11 is a worm gearing for connecing dish, 12.
Specific embodiment
Device is attached in the oil transport pipeline as shown in drawings, drive valve rod 9 and rotate by handwheel, worm gearing 12, thereby driving spheroid 6 rotates, when the perforate position on the spheroid 6 rotates to as shown in drawings state, whole oil circuit is unimpeded, rotate when drive valve rods 9 by worm gearing 12, thereby when the perforate position that drives spheroid 6 rotated to the perpendicular position of shown position, whole oil circuit was closed.In the process that oil circuit is opened and closed, it is bigger particularly to close in the closed procedure pressure of ducted oil, along with the bigger variation and the hyperbaric environment of temperature, in metal o-ring 4 positions, easily forms seepage.Utilization metal o-ring 4 in the utility model, it can adapt to the environment of superhigh temperature, ultralow temperature, high pressure.Realize ne-leakage under the states such as superhigh temperature, ultralow temperature, high pressure, thereby realized sealing.
