Abstract
The utility model discloses a novel stop valve which comprises a valve body, a valve rod, a hand wheel, a valve clack and a valve cap, wherein the valve body comprises an inlet pipeline and an outlet pipeline; the valve cap is in threaded connection with the valve body; the valve rod is mounted inside the valve body; the valve rod is fixedly connected with the valve clack. The novel stop valve is characterized in that a leakage prevention device is mounted on the valve cap, is mounted at the upper end opening of the valve cap, is placed on the valve rod outer ring face, and comprises a mounting cover, a positioning sleeve, filler, a filler pad and an elastic element; the positioning sleeve is mounted between the mounting cover and the valve rod; the filler is mounted at the lower end of the positioning sleeve; the filler pad is mounted at the lower end of the filler; one end of the elastic element is propped against the filler pad, and the other end of the elastic element is placed on a limiting annular table arranged on the valve cap. According to the utility model, the pneumatic-manual normally-opened urgent stop valve is designed, the filler pressing is adopted as the initial sealing, and the filler sealing property is enhanced along with the medium pressure increment; the stop valve has the self-sealing function, does not requires manual maintenance, and is applicable to high-medium pressure conveying pipeline.
Description
Technical field
The utility model relates to a kind of stop valve, particularly a kind of novel stop valve.
Background technique
In the past, the ammonia valve of chemical industry, was generally the common valve that sealability is general.Common valve is from material or structure does not possess special-purpose feature, and it is bad that on the one hand this valve respectively seals the sealability at position, can not stop well dielectric leakage; Under the poisonous and hazardous process conditions of burn into, often poor sealing performance, easily leaks on the other hand, housing is easily bored a hole, and working life is short, can not meet the specific (special) requirements of permanently effective conveying poisonous medium, once and ammonia leaks out, can bring very large harm to surrounding enviroment and personal safety.
Model utility content
The purpose of this utility model is that a kind of novel stop valve of a kind of long service life, good seal performance is provided in order to solve above-mentioned the deficiencies in the prior art.
1, to achieve these goals, a kind of novel stop valve that the utility model is designed, comprise valve body, valve rod, handwheel, flap and valve gap, described valve body comprises inlet pipe road and goes out pipeline, valve gap is fixedly connected with valve body, valve rod is arranged in valve body, valve rod is fixedly connected with flap, it is characterized in that: on described valve gap, leakage preventer is installed, described leakage preventer is arranged on valve gap upper end-hole, and be placed in valve rod outer ring face, described leakage preventer comprises mounting cover, setting sleeve, filler, Packing seat and elastic component, described setting sleeve is arranged between mounting cover and valve rod, described filler is arranged on setting sleeve lower end, filler lower end is provided with Packing seat, described elastic component one end and Packing seat are conflicted, the other end is placed in the limited ring dais arranging on valve gap, flap upper-end surface is provided with seal ring, corresponding valve gap is provided with projection.
Preferably, described flap lower end is provided with pressing plate, and pressing plate is mounted on flap by screw.
Preferably, described flap is provided with sealing surface.
Preferably, between described flap and valve rod, stuffing box gland is installed.
A kind of novel stop valve that the utility model obtains, the filler of take pressing as initial sealing, along with pressure medium rise Reliability of Packing Seal strengthen, both there is self-sealing function, without manual maintenance, be applicable to high pressure conveyance conduit, must be by the complete standard-sized sheet of valve when this valve is all provided with seal ring, valve opening, use seal ring to do to be far smaller than common valve in order to increase filler working life, this valve opening slim and graceful, steering force.
