Description
Technical field
The utility model relates to a kind of taper valve core one-way valve.
Background technique
One-way valve can be widely used in the occasion of the unidirectional cut-out fluid of all needs in the fluid delivery process, is mainly used in the import and export of pump.Can substitute the one-way valve of structural types such as common spherical valve core, plane spool, improve the reliability of sealing, prolong valve working life.The less occasion of medium impurities that requires pump to carry can suitably select for use different valve materials to come anticorrosion and heatproof according to the characteristics of applying working condition.Good at chemical field highly versatile, promotional value height, application prospect.
Referring to Fig. 1, it is depicted as traditional one-way valve, comprise valve seat 10, valve gap 20, spool 30 is steel balls of a 20, rely on the spring 40 of valve internal that impacting force is provided, the seal form of it and valve seat 10 belongs to (list) linear sealing, and the steel ball spherical surface all is a sealing surface, and along with the continuous rotation of steel ball in valve body, sealing surface also constantly changes.Therefore,, valve invalidation will be caused, certainly, valve invalidation can be caused too if defective appears in valve seat in case defective appears in sphere.From actual use condition, the reason of valve invalidation (airtight not tight) mainly contains five.
1. this type of valve is very high to the requirement of steel ball ovality, but the control difficulty is quite high, if exceed accuracy rating, the sealing effect of valve will be had a greatly reduced quality, and this phenomenon often takes place in the actual using process, and all there is this type of situation in the domestic and imported valve.
2. provide power owing to closing of valve relies on spring, and this spring force is unadjustable, the sealing impacting force that the new valve medi-spring produces is big, causes the valve base sealing facial disfigurement on the one hand, and distortion sometimes is quite serious; Cause the steel ball surface to produce very dark annular groove mark on the other hand.And along with the prolongation of active time, the aging sealing of spring impacting force will descend, and sealing effect also just descends thereupon, and these situations all took place on inlet valve spare part and homemade valve spare part.
3. because steel ball frequent and valve gap rigid collision in the valve opening process is easy to cause the surface failure of steel ball, thereby has destroyed the sealed precision of sealing surface, the sealing effect nature is just poor.And, because this kind valve is the single line sealing, lacking certain compensation characteristic, leakage phenomenon comes out soon.
4. steel ball relies on spring that power is provided in valve seat, lacks necessary position structure, so the valve opening and closing precision will be subjected to certain influence, thereby influences sealing effect.
5. there is tiny pit in situation about damaging from valve on steel ball and valve base surface, the especially sealing surface of seat, illustrate that traditional one-way valve is very responsive to the solid particle that contains in the material, these particles continuingly act on the sealing surface, can cause sealing surface impaired, and sealing effect descends.
Summary of the invention
The purpose of this utility model is to design a kind of taper valve core one-way valve, and it has good airtight performance, and, long service life.
For achieving the above object, the technical solution of the utility model is,
A kind of taper valve core one-way valve comprises, valve seat, and it has a cavity body structure, and the one end has a through hole, and this via openings place sidewall is a cone structure; Valve gap is connected in the other end of valve seat, and its diapire central authorities have a projection, have the guide channel that runs through valve gap on this projection; Also have through hole on the diapire around the projection; Spool, it comprises a directional post and the fixing taper valve core of one end; This directional post stretches in the guide channel of valve gap, and taper valve core cooperates with valve seat through-hole; Spring is sheathed on the spool directional post, and the one end is against the valve gap diapire, and the other end is against taper valve core one side of directional post.
Further, described valve gap and valve seat are for being threaded.
A step is also established in described spool directional post and taper valve core joint, and described spring is fixed in this step.
The sealing surface of described taper valve core, the sealing surface of valve seat through-hole adopt Hardmetal materials.
Valve gap and valve seat are screwed into the pretightening force that the degree of depth guarantees spring by screw thread simultaneously by being threaded; Spool is realized accurately location by the spool guide channel that spool guide-localization post penetrates on the valve gap; Spool cooperates formation sealing spoke with valve seat, the spool cone structure has certain leading role, and certain self compensation function is arranged simultaneously.
The beneficial effects of the utility model are,
The utility model spool adopts cone structure, makes it that certain leading role be arranged, and certain self compensation function is arranged simultaneously, guarantees airtight performance; Simultaneously, valve gap and valve base chamber adopt threaded connection mode, and the assurance initial tension of spring can be regulated; Certain compensate function is arranged between sealing surface; Set up guide structure, improve spool and open and close precision; Improve flow velocity and effectively wash sealing surface.
Description of drawings
Fig. 1 is the structural representation of traditional one-way valve;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 2, taper valve core one-way valve of the present utility model comprises, valve seat 1, and it has a cavity body structure 100, and the one end has a through hole 11, and these through hole 11 opening sidewalls are cone structure 12; Valve gap 2 is threadedly connected to the other end of valve seat 1, and its diapire 21 central authorities have a projection 22, have the guide channel 23 that runs through valve gap 2 on this projection 22; Also have 8 through holes 24 on the diapire 21 around the projection 22; Spool 3, it comprises a directional post 31 and the fixing taper valve core 32 of one end; This directional post 31 stretches in the guide channel 23 of valve gap 1, and taper valve core 32 cooperates with valve seat 1 through hole 11; Spring 4 is sheathed on spool 3 directional posts 31, and the one end is against valve gap 2 diapires 21, and the other end is against taper valve core 32 1 sides of directional post 31; Spool directional post 31 is also established a step 33 with taper valve core 32 joints, and described spring 4 is fixed in this step 33.
