Description
Technical field
The utility model relates to a kind of ball valve, particularly the two-door ball valve of a kind of combustion gas.
Background technique
Two-door ball valve is a kind of valve that is respectively equipped with spheroid at two connecting passage places of valve body, the opening and closing time of this type of valve is short, keying dynamics is little, it is mainly by valve body, valve gap, the symmetrical connection chamber that is provided with two connecting passages and connects two connecting passages on valve body, between two connecting passages and connection chamber, be respectively equipped with spheroid, valve body is provided with the valve seat with ball seal, valve gap is provided with driving mechanism, between driving mechanism and two spheroids, by linkage rack, implement interlock, when forming two spheroids with this, control or control respectively.Yet the sealing surface between spheroid and valve seat easily causes wearing and tearing in running, and the pressure medium in valve body is when excessive, and swinging easily appears in spheroid in running, and the sealing between spheroid and valve seat cannot be protected.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of good airproof performance, the stable two-door ball valve of combustion gas.
For achieving the above object, the utility model provides following technological scheme: the two-door ball valve of a kind of combustion gas, include valve body, valve gap, the symmetrical connection chamber that is provided with two connecting passages and connects two connecting passages on valve body, between two connecting passages and connection chamber, be respectively equipped with spheroid, valve body is provided with the valve seat with ball seal, between spheroid and valve seat, be provided with Sealing, valve gap is provided with driving mechanism, between driving mechanism and two spheroids, by linkage rack, be connected, it is characterized in that: the sealed end place of described spheroid and valve seat is provided with the cavity of accommodating valve seat, the seal face of the coated valve seat of sidewall of cavity, between spheroid and valve seat, be provided with positioning and guiding assembly, on spheroid, on the bottom end face of cavity, offer standing groove, Sealing is installed in this standing groove, and between the bottom end face of standing groove and Sealing, be provided with elasticity and compress assembly.
Adopt technique scheme, by the cavity of accommodating valve seat and the seal face of the coated valve seat of cavity side walls are set on spheroid, arrange and make the cavity on spheroid be essentially guide groove like this, valve seat can be guide rail, make spheroid stable, when the operation of spheroid and valve seat can keep stable state during as for valve base sealing, can effectively prevent that spheroid is subject to the impact of pressure medium and shakes, the sealing of valve seat and spheroid is guaranteed, the effect of auxiliary positioning and the guiding of spheroid is played in the setting of positioning and guiding assembly, stability while further having guaranteed spheroid operation, the setting that elasticity compresses assembly be when guaranteeing that spheroid remains static and valve seat between sealing.
The utility model is further set to: positioning and guiding assembly include be located at the some ring-type positioning convex strips on spheroid cavity bottom end face and be opened on valve seat and with the ring-type positioning and guiding groove of ring-type positioning convex strip adaptation.
Adopt technique scheme, arrange so simple in structure, easy to process.
The utility model is further set to: elasticity compresses assembly and includes one end and standing groove bottom end face and conflict, the spring that compresses of the other end and Sealing conflict.
Adopt technique scheme, setup cost is cheap like this, and more reliable and stable to the conflict pressure of Sealing.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
As Fig. 1, the two-door ball valve of a kind of combustion gas shown in Fig. 2, include valve body 1, valve gap 2, the symmetrical connection chamber 12 that is provided with two connecting passages 11 and connects two connecting passages 11 on valve body 1, between two connecting passages 11 and connection chamber 12, be respectively equipped with spheroid 3, valve body 1 is provided with the valve seat 4 with spheroid 3 sealings, between spheroid 3 and valve seat 4, be provided with Sealing 5, valve gap 2 is provided with driving mechanism 6, driving mechanism 6 can be motor or manual pulley, between driving mechanism 6 and two spheroids 3, by linkage rack 7, be connected, the sealed end place of spheroid 3 and valve seat 4 is provided with the cavity 31 of accommodating valve seat 4, the seal face of the sidewall 311 coated valve seats 4 of cavity 31, on spheroid 3, on the bottom end face of cavity 31, offer standing groove 32, Sealing 5 is installed in this standing groove 32, and between the bottom end face of standing groove 32 and Sealing 5, be provided with elasticity and compress assembly 33.In such scheme, by the cavity 31 of accommodating valve seat 4 and the seal face of cavity 31 sidewall 311 coated valve seats 4 are set on spheroid 3, arrange and make the cavity 31 on spheroid 3 be essentially guide groove like this, valve seat 4 can be guide rail, make spheroid 3 stable, when spheroid 3 seals as for valve seat 4 with valve seat 4 operations, can keep stable state, can effectively prevent that spheroid 3 is subject to the impact of pressure medium and shakes, valve seat 4 and the sealing of spheroid 3 are guaranteed; The setting that elasticity compresses assembly 33 be when guaranteeing that spheroid 3 remains static and valve seat 4 between sealing.In the utility model embodiment, in order to reduce costs, make Sealing 5 can be subject to the power of conflicting comparatively reliably, elasticity compresses assembly 33 and includes one end and standing groove 32 bottom end faces and conflict, and the other end and Sealing 5 are conflicted compresses spring, certain, it should be noted that, this elasticity compresses assembly 33 and also can be and have flexible pressing plate or elastic spring, is also feasible, and Sealing 5 is selected fluorine rubber pad.
