Abstract
The utility model discloses a one-way valve. The utility model comprises a valve core and a valve body, wherein the valve core is composed of a T-shaped guide core rod, a compression spring, an elastic gasket and a guide core seat, and both ends of the valve body are provided with internal screw threads. The middle part of the valve body is provided with a valve hole seat of which the diameter is smaller than the cavity diameter of the valve body, and the valve core is arranged between a location hole sheet and the valve hole seat in the cavity of the valve body. A valve core component with automatic reset and cutoff is composed of the compression spring and the elastic gasket, thereby, the defect that noise is sent out at the time of reverse cutoff is avoided when the utility model is used. Preferable effects are obtained when the valve is applied to water heaters.
Description
The utility model relates to the improvement that pipe stops valve, especially a kind of one-way cock, and it belongs to the FLUID TRANSPORTATION technical field.
In the prior art, one-way cock often is applied in the pipe-line system, plays a part unidirectional conducting and oppositely ends.General one-way valve structures is unreasonable, and unidirectional conducting is not smooth, not exclusively and between parts can make a noise when ending, and spool cooperates imprecision with valve seat, and is easy to wear between parts, and working life is short.
The purpose of this utility model is the deficiency that will overcome above-mentioned one-way valve, designs a kind of one-way cock, and it has the conducting smoothness, by tight, be active in one's movements between parts, lightly, buffer function is arranged, noiseless characteristics automatically switch.
Task of the present utility model has following technological scheme to finish, developed a kind of one-way cock, it comprises that the pipe fitting two ends have the valve body and the spool of internal thread, in this valve body middle part cavity, be provided with the valve opening seat of diameter less than footpath, valve body chamber, also be provided with the positioning hole sheet in the cavity of this seat top, hole, the spool of unidirectional conducting is installed between this hole seat and positioning hole sheet, this spool shutoff is on this hole seat, and can be above this hole seat, move along the center guide hole axle direction of positioning hole sheet is upper and lower, thereby constitute this spool folk prescription to the state of opening or closing this hole seat.
This one-way cock, described spool, it comprises: "T"-shaped guiding core bar, pressure spring, resilient pad and guiding core print seat, wherein the upper end bar of this core bar passes the center guide hole of positioning hole sheet, connect in the vestibule that solid guiding core print seat falls to being sitting in this hole seat with this core bar and can be in this vestibule upper and lower moving; Between the horizontal end plate of this core bar and this core print seat upper-end surface, be embedded with resilient pad, the outward edge ring plate of this pad just in time shutoff is being provided with the pressure spring of this pad of shutoff on this vestibule end face that reset between the horizontal end plate of location piece and this core bar on the vestibule end face of this hole seat.
This one-way cock, described positioning hole sheet, except that being provided with the center guide hole, its periphery also is provided with arranges orderly through hole on its sheet plate, and the shape in this hole can be a circular port, also can be fan shaped borehole.
This one-way cock, the guiding core print seat of fast spool, it can fall to being sitting in the core print seat shape in the vestibule of this hole seat glibly, can be frustoconic shape, its big bottom surface diameter of a circle should equal or the vestibule diameter of big slightly this hole seat of son; It also can be terrace with edge shape with this core print seat form fit.
One-way cock advantage of the present utility model has: owing to designed the valve core structure with resilient pad and Returnning spring, make this valve when oppositely ending, be active in one's movements automatic cut-off, and noise free, this is the effect that the buffer function owing to elastic caoutchouc matter pad produces.Owing to designed orderly circle or the fan-shaped pylone of arrangement on the positioning hole sheet, guaranteed this valve conducting smoothness, and by the time by the vestibule of the center guide hole of this hole sheet and valve opening seat as the guiding core bar of spool and the moving track of guiding core print seat, resilient pad is under the effect of resetting pressure spring and reverse pressure head when guaranteeing to end, just in time shutoff is on the vestibule end face of this hole seat, realize automaticallying switch noiseless effect by tight.Less because of the spring force of pressure spring, the pressure head to fluid is enough to this pad of ejection breakdown down, and by positioning hole sheet smoothness freely.
Embodiment's accompanying drawings of the present utility model is as follows:
Fig. 1 is the structure sectional view of one-way cock.
Fig. 2 is the structure plan view of one-way cock.
The one-way cock of making referring to Fig. 1 is the pipe fitting of brass material, and it has the valve body 1 of internal thread for two ends, is provided with the valve opening seat 9 of diameter less than footpath, valve body chamber in this valve body 1 in the cavity of position.Also be provided with positioning hole sheet 2 in the cavity of these hole seat 9 tops.The spool of unidirectional conducting is installed between this hole seat 9 and positioning hole sheet 2.This spool shutoff and can be above this hole seat 9 on this hole seat 9, moves along the center guide hole 11 of positioning hole sheet 2 is axially upper and lower, thereby constitute this spool folk prescription to the state of opening or closing this hole seat 9.
The designed spool of this one-way cock comprises: "T"-shaped guiding core bar 8, pressure spring 3, resilient pad 5 and guiding core print seat 6.The upper end bar 8 of this core bar 8 ' the pass center guide hole 11 of positioning hole sheet 2 wherein.Connect in the vestibule that solid guiding core print seat 6 falls to being sitting in this hole seat 9 with this core bar 8 and can be in this vestibule upper and lower moving.Between the horizontal end plate 4 of this core bar 8 and this core print seat 6 upper-end surfaces, be embedded with resilient pad 5, outside this pad 5; The edge ring plate just in time shutoff on the vestibule end face 10 of this hole seat 9.Be provided with the pressure spring 3 of this pad 5 of shutoff on this vestibule end face 10 that reset between the horizontal end plate 4 of positioning hole sheet 2 and this core bar 8.
The positioning hole sheet 2 that this one-way cock is designed, except that being provided with center guide hole 11, its periphery also is provided with arranges orderly through hole 12 on its sheet plate.The shape in this hole 12 can be a circular port, also can be fan shaped borehole.
The guiding core print seat 6 of the spool that this one-way cock is designed, it can fall to being sitting in the vestibule of this hole seat 9 glibly, its core print seat 6 shapes are a kind of frustoconic shape, its big bottom surface diameter of a circle should be equal to or slightly greater than the vestibule diameter of this hole seat 9, be beneficial to this core print seat 6 and in this vestibule, move smooth and unlikely coming off, guarantee unidirectional conducting, the effect of oppositely ending realizes.
