Abstract
The utility model discloses a bi-directional breather valve, which includes a valve core and a valve body, wherein the valve core and the valve body are propped and matched with a seal ring on a valve seat by adopting axial seal structures, so that the two seal structures can not interfere each other during operation of the breather valve, and the efficiency and reliability of the sealing can be ensured; and further, the seal ring mounted on the valve seat are embedded completely in a seal groove, and the upper end surface of the seal ring is flush with a notch of the seal groove. On one hand, the bi-directional breather valve is enabled to be more compact in structure, can further reduce the size and the manufacture cost of the breather valve at the same time without lowering the function of the breather valve, and on the other hand, the deformation of the seal ring under compression can be further avoided, and the seal effect of the bi-directional breather valve is improved.
Description
Technical field
The utility model relates to a kind of inhalation valve, and definite saying so relates to a kind of two-way inhalation valve that is used for the equalizing reservoir external and internal pressure.
Background technique
Inhalation valve mainly is installed in the inside and outside pressure that is used for equalizing reservoir on normal pressure or the low-pressure gas-liquid container.Chinese patent open file CN2695747Y discloses a kind of inhalation valve; This inhalation valve comprises valve body, valve base and spool; Spool guiding is slided and is arranged in the pilot hole that valve base center correspondence offers; The valve base inboard is provided with expiration spring and the air-breathing spring with the coaxial setting of pilot hole, and on spool, is fixed with the spring of exhaling and contacts the back-up ring that cooperates, and in valve body, is provided with air-breathing spring and contacts the web plate that cooperates; On valve base and end face that spool contacts, seal ring is installed, the sealing circle simultaneously with spool on sealing surface and the applying of the sealing surface on the valve body.Spool adopts the axial seal structure of axial force distribution to cooperate with seal ring on the valve base in this inhalation valve; Valve body then adopts cone structure to cooperate with seal ring; Adopt the defective of this sealing configuration to be: the conical surface crush seal circle of valve body causes seal ring to produce torsional deformation easily, thereby destroys the sealing effect between seal ring and the spool; And after this seal ring is installed on the valve base, its half embed in the annular groove of valve base, the end face that half protrudes in valve base, making has bigger gap between valve base and the valve body of this inhalation valve, structure is compact inadequately.
The model utility content
The purpose of the utility model is: the two-way inhalation valve that a kind of compact structure, good sealing effect are provided.
The technological scheme of the utility model is: a kind of two-way inhalation valve; Establish the valve body of valve pocket in comprising; End in valve pocket in the valve body is provided with pneumostome; The guiding activity is changeed and to be furnished with the valve base that is used for opening and closing pneumostome and to be equipped with the spool with this valve base corresponding matching in this valve base guiding in the valve pocket; Be provided with the through hole that is communicated with pneumostome and valve pocket in the valve base; And on the end face of pneumostome, be positioned at the seal groove of the periphery of through hole offering at valve base and be embedded with seal ring through correspondence, on said valve interior wall and spool, be respectively equipped with simultaneously the sealing configuration of conflicting and being sealed and matched with the sealing circle, the sealing configuration on the said spool be along on the valve base movement direction towards the annular boss of seal ring extension; The exterior edge face of described seal ring flushes with the notch of described seal groove, and the sealing configuration on the said valve body is to be positioned at the annular flange flange that protrude along the valve base movement direction towards seal ring the spool periphery on the valve interior wall.
The longitudinal section of described annular flange flange on the valve base movement direction is conical structure.
In the utility model; Spool and valve body all adopt the axial seal structure that is provided with along the valve base movement direction to conflict with the seal ring on the valve base to cooperate, make mutual noninterference when inhalation valve is worked between this two sealing configuration, guaranteed the validity and the reliability that seal; And the seal ring of installing on the valve base embeds in the seal groove completely; The upper-end surface of seal ring flushes with seal groove notch place, makes that on the one hand the structure of this two-way inhalation valve is more compact, and it can further reduce the volume of inhalation valve when not reducing the inhalation valve effect; Reduce the manufacture cost of inhalation valve; On the other hand, can further avoid the seal ring compressive deformation, improve the sealing effect of this two-way inhalation valve.
Description of drawings
Fig. 1 is the structural representation of the two-way inhalation valve specific embodiment of the utility model;
Fig. 2 is the A portion enlarged view among Fig. 1.
Embodiment
The specific embodiment of the two-way inhalation valve of the utility model vertically is set to example with two-way inhalation valve; Like Fig. 1, shown in Figure 2, this two-way inhalation valve is mainly reached and is formed with the big spring seat 9 of air-breathing spring 6 corresponding settings with the submissile spring abutment 8 of expiration spring 7 corresponding settings by valve body 1, filter assemblies 2, spool 3, valve base 4, air-breathing spring 6, expiration spring 7.Wherein, be provided with valve pocket in the valve body 1, the end that valve pocket is positioned at valve body is provided with pneumostome; Valve base 4 guiding are slidingly mounted in the valve pocket of valve body 1; In this valve base 4, be provided with the through hole that is communicated with pneumostome and valve pocket, and the seal groove of the periphery that on the upper-end surface of pneumostome, is positioned at through hole at valve base 4 through the correspondence setting be embedded with seal ring 5, in the utility model; Valve base 4 is the plane towards the upper-end surface of pneumostome, and the exterior edge face of sealing circle 5 flushes with corresponding valve seat 4 upper-end surfaces.Spool 3 has a seal disc 31 that is oppositely arranged with valve base 4 upper-end surfaces and is located at seal disc 31 centers and valve rod 30 that valve base 4 guiding are slidingly matched; And be provided with the annular boss of conflicting and being sealed and matched in the circumferential edge of sealing dish 31 with seal ring 5; This annular boss is conical structure on the movement direction of valve base 4; Simultaneously; The periphery that on the inwall of valve body 1, is positioned at seal disc 31 also is provided with a sealing configuration that is sealed and matched with sealing circle 5, and in the present embodiment, the sealing configuration of this valve body 1 comprises that the annular retaining that is convexly set on valve body 1 inwall is along 10; And the annular flange flange that on the bottom surface of valve base 4, is equipped with to seal ring 5 protrusions on this annular retaining edge 10, this annular flange flange also is conical structure on valve base 4 movement directions.Air-breathing spring 6 all is set on the valve rod 30 of valve base 4 bottoms with expiration spring 7; Air-breathing spring 6 is all conflicted on the lower end surface of valve base 4 away from pneumostome with the upper end of expiration spring 7; Big spring seat 9 is fixed on the inner hole wall of valve body 1 lower end, and submissile spring abutment 8 is fixed on the underpart of valve rod 30.
