Background technique
Ball valve is that open-shut device (spheroid) is driven by valve rod, and around the valve that the axis of valve rod rotates.Be mainly used in blocking or connect the medium in pipeline, also can be used for the regulating and control of fluid.Ball valve, according to the difference of driving mode, can be divided into: pneumatic ball valve, electric ball valve and manual ball valve.
At present, manual ball valve is as widely used a kind of valve, have install convenient, use the advantages such as simple, but shortcoming is: in long-time using process, owing to being rotated by handle force, thus colliding and causing damage easily appears in the retaining positions place making both valve body and valve rod be formed, thus reduce valve working life.
Model utility content
The utility model embodiment technical problem to be solved is, provides a kind of manual ball valve, and reduction valve rod and valve body are positioned at the damage at the retaining positions place that the two is formed, and extend the working life of valve.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of manual ball valve, comprise valve body, valve rod, spheroid and handle, the two ends of described valve rod are connected with the handle be positioned at outside described valve body and the spheroid that is positioned at described valve body respectively, described valve interior wall is formed with a groove, and between the two ends of described valve rod, be formed with the flange be installed in described groove, and on the end face of described flange away from described spheroid side and/or described groove on the inwall of described spheroid side, be provided with thrust washer for cushioning.
Wherein, described manual ball valve also comprises locating washer, and described locating washer between valve body and described handle, and is socketed on the outer wall of described valve rod.
Wherein, described locating washer extends certain length from its perimeter edge edge towards described handle center's point direction.
Wherein, described valve body comprises left valve barrel and right valve barrel, and is provided with described spheroid and described groove in described left valve barrel; Wherein, middle part pad is provided with between described left valve barrel and described right valve barrel.
Wherein, described left valve barrel and described right valve barrel are provided with valve seat with the described spheroid place of matching respectively.
Wherein, fixed by screw between described left valve barrel and described valve rod.
Implement the utility model embodiment, there is following beneficial effect:
1, in the utility model embodiment, coordinate because the groove of valve body holds mutually with the flange of valve rod, and on the end face of flange away from spheroid side and/or groove on the inwall of spheroid side, be provided with thrust washer for cushioning, avoid because handle force is rotated and collision between valve body and valve rod may be caused to produce damage, thus extending the working life of valve;
2, in the utility model embodiment, owing to being provided with from perimeter edge along the locating washer extending certain length towards handle center's point direction, avoid because handle force is rotated and collision between handle and valve body may be caused to produce damage, thus extending the working life of valve.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, the accompanying drawing obtaining other according to these accompanying drawings still belongs to category of the present utility model.
The structural representation of the manual ball valve that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structural representation of locating washer in Fig. 1;
Wherein: 1-valve body, 11-groove, 12-left valve barrel, 13-right valve barrel, 2-valve rod, 21-flange, 3-spheroid, 4-handle, 5-thrust washer, 6-locating washer, pad in the middle part of 7-, 8-valve seat, 9-screw.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The direction that the utility model is mentioned and position term, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " top ", " bottom ", " side " etc., be only the direction with reference to accompanying drawing or position.Therefore, the direction of use and position term are in order to illustrate and to understand the utility model, but not the restriction to the utility model protection domain.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of manual ball valve, comprise valve body 1, valve rod 2, spheroid 3 and handle 4, the two ends of valve rod 2 are connected with the handle 4 be positioned at outside valve body 1 and the spheroid 3 that is positioned at valve body 1 respectively, wherein, valve body 1 inwall is formed with a groove 11, and between the two ends of valve rod 2, be formed with the flange 21 be installed in groove 11, and on the end face of flange 21 away from spheroid 3 side and/or groove 11 on the inwall of spheroid 3 side, be provided with thrust washer 5 for cushioning.
Should be noted that, rotated by handle 4, when realization opens or closes manual ball valve, a downward pressure may be applied just can rotate, now because handle 4 presses down, valve rod 2 is moved upward, thus cause valve rod 2 flange 21 to collide with the inwall of valve body 1 groove 11 towards spheroid 3 side, therefore in prolonged and repeated switch manual ball valve process, there will be both valve body 1 and valve rod 2 and occur collsion damage, and the setting of thrust washer 5 is used for buffering valve body 1 and the collision both valve rod 2, avoid the generation damaged, thus extend the working life of valve.
In order to extend the working life of valve further, avoid applying to occur that collsion damage appears in both valve body 1 and valve rod 2 to upper pulling force because handle 4 rotates, therefore manual ball valve also comprises locating washer 6, and locating washer 6 between valve body 1 and handle 4, and is socketed on the outer wall of valve rod 2.
In order to further extend the working life of valve, avoid occurring that collsion damage appears in both valve body 1 and handle 4 because handle 4 rotates applying down pressure, therefore locating washer 6 extends certain length from its perimeter edge edge towards handle 4 central point direction, handle 4 and valve body 1 is made not to come in contact like this, as shown in Figure 2.
Further, valve body 1 comprises left valve barrel 12 and right valve barrel 13, and is provided with spheroid 3 and groove 11 in left valve barrel 12; Wherein, be provided with middle part pad 7 between left valve barrel 12 and right valve barrel 13, improve sealing therebetween.
Further, left valve barrel 12 and right valve barrel 13 are provided with valve seat 8 with spheroid 3 place of matching respectively.
Further, fixed by screw 9 between left valve barrel 12 and valve rod 2.
Implement the utility model embodiment, there is following beneficial effect:
1, in the utility model embodiment, coordinate because the groove of valve body holds mutually with the flange of valve rod, and on the end face of flange away from spheroid side and/or groove on the inwall of spheroid side, be provided with thrust washer for cushioning, avoid because handle force is rotated and collision between valve body and valve rod may be caused to produce damage, thus extending the working life of valve;
2, in the utility model embodiment, owing to being provided with from perimeter edge along the locating washer extending certain length towards handle center's point direction, avoid because handle force is rotated and collision between handle and valve body may be caused to produce damage, thus extending the working life of valve.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
