Abstract
The utility model discloses an impurity proof ball vale which comprises a valve body, a valve seat and a ball body. An O-shaped seal ring and a spring are arranged between the valve body and the valve seat, an insertion groove is opened in the valve seat, an insertion piece is arranged in the insertion groove, bosses which are mutually matched are arranged on the valve body and the valve seat on the front side of the O-shaped seal ring respectively, and an impurity holding cavity is formed between the two bosses which are mutually matched. According to the impurity proof ball vale, the bosses are arranged on the valve body and the valve seat on the front side of the O-shaped seal ring respectively, and the impurity holding cavity is formed between the two bosses, so that impurities are prevented from permeating to the O-shaped seal ring, and the sealing effect of the ball valve is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of anti-impurity ball valve.
Background technique
One of widely used valve of ball valve, its working principle is the same with stopcock, all is to make valve opening and closing by rotary spool, but lighter than stopcock switch, relative volume is little, can make big-diameter ball valve.Ball valve sealing is reliable, and is simple in structure, easy to maintenance, and sealing surface and the spheroid closed state of being everlasting is difficult for by the medium erosion, thereby is widely used in industries such as oil, chemical industry, metallurgy.
Referring to shown in Figure 1, the spheroid 3 that existing ball valve generally comprises valve body 1, valve seat 2 and seals, be provided with spring 4 and O-ring seals 5 between valve body 1 and the valve seat 2, offer slot on the valve seat, be provided with a nonmetallic plug-in unit 6 in the slot, the spheroid of ball valve is fixed, do not produce movement behind the pressurized, after valve seat is subjected to hydrodynamic pressure, produce mobile, so that plug-in unit can be pressed on the spheroid, seal with assurance.Yet ball valve is in the use of reality, and the impurity in the fluid can enter in the standing groove of O-ring seals, and then causes O-ring seals to lose efficacy, and finally causes whole ball valve to lose efficacy.
Summary of the invention
The utility model purpose provides a kind of anti-impurity ball valve, by the improvement to structure, has guaranteed the sealing effect of ball valve.
The technical solution of the utility model is: a kind of anti-impurity ball valve, comprise valve body, valve seat and spheroid, be provided with O-ring seals and spring between described valve body and the valve seat, offer slot on the described valve seat, be provided with plug-in unit in the described slot, the front side that is positioned at described O-ring seals on described valve body and the valve seat is respectively equipped with the boss that cooperatively interacts, and consists of the impurity accepting groove between the described boss that cooperatively interacts.
In the technique scheme, ball valve is by valve body, valve seat and the spheroid that seals consist of, be provided with O-ring seals and spring between valve body and the valve seat, be respectively equipped with the boss that cooperatively interacts in the forward position that is positioned at described O-ring seals on valve body of the present utility model and the valve seat, consist of an impurity accepting groove between two boss that cooperatively interact, the relatively more difficult placement location direction toward O-ring seals of impurity in the fluid that is arranged so that of boss is permeated, avoided the inefficacy of O-ring seals, even and a small amount of infiltration arranged, also can be housed in the impurity accepting groove, thereby guarantee the sealing effect of ball valve.
The utility model has the advantages that:
1. the utility model arranges respectively the boss that cooperatively interacts by the front side that is positioned at described O-ring seals at valve body and valve seat, two boss that cooperatively interact consist of the impurity accepting groove, the inefficacy of O-ring seals has been avoided in the setting of boss and impurity accepting groove, has guaranteed the sealing effect of ball valve;
2. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is ball-valve structure schematic representation in the prior art;
Fig. 2 is the utility model embodiment one structural representation.
Wherein: 1, valve body; 2, valve seat; 3, spheroid; 4, spring; 5, O-ring seals; 6, plug-in unit; 7, valve body; 8, valve seat; 9, spheroid; 10, O-ring seals; 11, spring; 12, plug-in unit; 13, boss; 14, impurity accepting groove.
Embodiment
Embodiment one: referring to shown in Figure 2, a kind of anti-impurity ball valve, comprise valve body 7, valve seat 8 and spheroid 9, be provided with O-ring seals 10 and spring 11 between described valve body 7 and the valve seat 8, offer slot on the described valve seat 8, be provided with plug-in unit 12 in the described slot, the front side that is positioned at described O-ring seals 10 on described valve body 7 and the valve seat 8 is respectively equipped with the boss 13 that cooperatively interacts, and 13 of the described boss that cooperatively interacts consist of impurity accepting groove 14.
Ball valve in use, offer respectively the boss that cooperatively interacts on valve body and the valve seat, consist of the impurity accepting groove between two boss, arranging of boss increased the difficulty of the impurity in the fluid to the infiltration of O-ring seals direction, even a small amount of infiltration is arranged, these impurity also can be housed in the impurity accepting groove, thereby have guaranteed the sealing effect of ball valve.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
