Abstract
A conveniently opened cock valve consists of a valve body, a valve cover, a cock, a bearing and a roller group, wherein a channel is formed in the cock, a groove is formed in the wall of the cock, the roller group is arranged in the groove, an oil channel is formed in the upper end of the cock, a valve rod channel is formed in a valve rod, a filler is padded between the valve rod and the valve body and compressed by a filler gland, a groove is formed in the top end of the filler gland to enable a gland bearing to be arranged in the groove, a groove is formed in the bottom of the valve body, and a base bearing is placed in the groove in the bottom of the valve body; when the cock is in a closed state, seal grease is injected into the oil channel through the valve rod channel, so that the roller group in the cock groove is fully lubricated; when the cock is in an open state, a medium flows into a medium inlet, flows through the channel and subsequently flows out of a medium outlet. When the valve rod rotates, due to actions of the bearing and rollers, functions that the cock is subjected to first attachment, subsequent uncoupling, rotation, and final attachment seal during opening and closing of the valve are achieved.
Description
Technical field
The utility model relates to stopcock, is specifically related to a kind of light stopcock of opening.
Background technique
Stopcock is the rotary valve of closure member or plunger shape, by 90-degree rotation, make passway on valve plug identical with passway on valve body or separate, realize a kind of valve of opening or closing, stopcock is suitable for as cutting off and connect medium and shunting applicable most, but according to applicable character and the abrasion-resistance of sealing surface, sometimes also can be used for throttling.
At present, the stopcock on market is when opening or cutting out, in order to reach seal request, accuracy of manufacturing is had relatively high expectations, and faucet body and valve interior wall are realized sealing with fitting tightly of conical surface, therefore in rotation process, moment during unlatching is larger, opens more difficult.
Model utility content
The purpose of this utility model is to provide a kind of light stopcock of opening, and has to open that light, simple in structure, long service life, precision are high, good airproof performance.
The utility model adopts following technological scheme:
Open a light stopcock, by valve body, valve gap, cock, bearing and set of rollers, formed.
In described cock, have a passage, the medium inlet of passage and valve body, media outlet are on same level line, and described cock wall is provided with groove, is provided with set of rollers in groove.Described cock upper end is provided with oil duct.
In described valve rod, be provided with valve stem passage, valve stem passage communicates with the oil duct in cock, and cock oil duct two ends communicate with the groove in cock wall.Between described valve rod and valve body, be lined with filler, by Gland, compressed, Gland top has groove, and gland bearing be can be placed in groove.Described valve gap is bolted gland bearing to be placed in valve body.
Described valve body bottom has groove, is mounted with base bearing in groove, and described base is bolted base bearing to be placed in valve body.
When cock is closed condition, by valve stem passage, in oil duct, inject seal grease, make the set of rollers in cock groove lubricated fully.When cock is opening state, medium flows into from medium inlet, after the passage of flowing through, flows out from media outlet again.When valve rod rotates, due to the effect of bearing and roller, realized the cock of valve opening and closing process and first from being adjacent to, thrown off the function that rotation is more finally adjacent to sealing.
The utility model has the advantage of: open that light, simple in structure, long service life, precision are high, good airproof performance.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Wherein: 1. valve body, 2. valve gap, 3. cock, 31. passages, 32. oil ducts, 33. set of rollers, 4. valve rod, 41. valve stem passage, 5. Gland, 6. gland bearing, 7. base bearing, 8. base.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The utility model as shown in Figure 1, is a kind ofly opened light stopcock, valve body 1, valve gap 2, cock 3 and valve rod 4, consists of.
In described cock 3, have a passage 31, the medium inlet of passage 31 and valve body 1, media outlet are on same level line, and described cock 3 walls are provided with groove, are provided with set of rollers 33 in groove.Described cock 3 upper ends are provided with oil duct 32.
In described valve rod 4, be provided with valve stem passage 41, valve stem passage 41 communicates with the oil duct 32 in cock 3, and oil duct 32 two ends communicate with the groove in cock 3 walls.Between described valve rod 4 and valve body 1, be lined with filler, by Gland 5, compressed, Gland 5 tops have groove, and gland bearing 6 be can be placed in groove.Described valve gap 2 is bolted gland bearing 6 to be placed in valve body 1.
Described valve body 1 bottom has groove, is mounted with base bearing 7 in groove, and described base 8 is bolted base bearing 7 to be placed in valve body 1.
When cock 3 is closed condition, by valve stem passage 41, to the interior injection seal grease of oil duct 32, make the set of rollers 33 in cock 3 grooves lubricated fully.When cock 3 is opening state, medium flows into from medium inlet, after the passage 31 of flowing through, flows out from media outlet again.When valve rod 4 rotates, due to the effect of bearing and roller, realized valve opening and closing process cock 3 and first from being adjacent to, thrown off the function that rotation is more finally adjacent to sealing.
