Abstract
Two spherical ball valve, the right body of valve body comprising valve body and be linked together with valve body and the left body of valve body, two alleys are provided with in described valve body, be positioned at the first alley of its right-hand member and be positioned at the second alley of its left end respectively, described first alley and the second alley are separately installed with corresponding first spheroid and the second spheroid, described first spheroid and the second spheroid upper end, valve body outside is fitted with corresponding first driving mechanism and the second driving mechanism respectively, described valve body side is fitted with blowdown valve, in order to the clean blowdown in the first alley and the second alley, the utility model is when wherein any one spheroid occurs opening and closing halfway situation, this hidden danger is thoroughly eliminated in keying by another one spheroid, play the effect of a double insurance, and after damage appears in one of them spheroid, only need change or safeguard the spheroid end of damage, another one spheroid also works on, and like this, extends spheroid working life on the whole.
Description
Technical field
The utility model relates to a kind of ball valve, specifically refers to a kind of two spherical ball valve.
Background technique
Ball valve is a kind of common Flow valve.Its structure generally comprises valve body, valve gap, spheroid, valve rod and operating device composition, and wherein operating device and valve rod are linked, and actuate valve stem drives spheroid to rotate, and completes the switching motion of ball valve.In this structure, its valve rod and spheroid are that split arranges linkage installation, there is corner or spot as yet untouched by a clean-up campaign, the shortcoming that cleaning is inconvenient.In addition, on chemical industry, petroleum transportation pipeline, absolute Security is required to some medium transport, do not allow to exist because valve opening and closing does not thoroughly cause security incident, in prior art, for this situation, general is all be provided with to organize ball valve on same conveyance conduit more, space hold is large, and there is the drawback taken time and effort when organizing ball valve installation, demolition and maintenance more, also add extra installation cost and maintenance cost simultaneously.
Model utility content
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, provides a kind of reasonable in design, easy to clean, can play two spherical ball valves of double insurance to conveyance conduit.
In order to realize final purpose of the present utility model, intend adopting following technology:
Two spherical ball valve, the right body of valve body (2) comprising valve body (1) and be linked together with valve body (1) and the left body of valve body (5), two alleys are provided with in described valve body (1), be positioned at first alley (3) of its right-hand member and be positioned at second alley (4) of its left end respectively, first alley (3) and the second alley (4) are separately installed with corresponding first spheroid (30) and the second spheroid (40), the axis of described first spheroid (30) and the second spheroid (40) is in same level, and with valve body (1) dead in line, first spheroid (30) and the second spheroid (40) upper end, valve body (1) outside is fitted with corresponding first driving mechanism (31) and the second driving mechanism (41) respectively, in order to keep cleaning in the first alley (3) and the second alley (4), valve body (1) side is fitted with blowdown valve (10), in order to the clean blowdown in the first alley (3) and the second alley (4).
For convenience of adapting to the user demand of working site, described first driving mechanism (31) and the second driving mechanism (41) are any one in manual, electronic, pneumatic drive mechanism.
The beneficial effects of the utility model are:
1. the utility model devises the alley that two are positioned at same level axis on valve body, by corresponding spheroid equipped in alley and operating device, can ensure wherein ought occur that keying is not thorough by any one spheroid, and then when likely causing leakage or do not dam, this hidden danger is thoroughly eliminated by the keying of another one spheroid, play the effect of a double insurance, and by arranging two spheroid, after there is damage in one of them spheroid, only need change or safeguard the spheroid end of damage, another one spheroid also works on, like this, extend spheroid working life on the whole.
2. the utility model is provided with blowdown valve at the side of valve body, arranging of blowdown valve can regularly be cleaned two alleys, to ensure being sealed and matched of spheroid and alley, one of the ball valve lost of life mainly causes reason to be exactly spheroid wearing and tearing, regular blowdown can reduce the spheroid wear problem that spheroid causes because of factors such as impurity in pipeline, benefits the working life extending ball valve.
Accompanying drawing explanation
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model plan view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, two spherical ball valve, the right body of valve body (2) comprising valve body (1) and be linked together with valve body (1) and the left body of valve body (5), two alleys are provided with in described valve body (1), be positioned at first alley (3) of its right-hand member and be positioned at second alley (4) of its left end respectively, first alley (3) and the second alley (4) are separately installed with corresponding first spheroid (30) and the second spheroid (40), the axis of described first spheroid (30) and the second spheroid (40) is in same level, and with valve body (1) dead in line, first spheroid (30) and the second spheroid (40) upper end, valve body (1) outside is fitted with corresponding first driving mechanism (31) and the second driving mechanism (41) respectively, in order to keep cleaning in the first alley (3) and the second alley (4), valve body (1) side is fitted with blowdown valve (10), in order to the clean blowdown in the first alley (3) and the second alley (4).
Embodiment 1, first driving mechanism (31) does not work, first spheroid (30) is in normally open, the now keying of ball valve controls the unlatching of the second spheroid (40) mainly through the second driving mechanism (41) or closes, when the second spheroid (40) or the second driving mechanism (41) break down, when cannot normally open and close, the keying of valve body is now realized again by operation first driving mechanism (31) and the first spheroid (30), certainly, above-mentioned first driving mechanism (31) and the second driving mechanism (41) working state interchangeable, namely the first driving mechanism (31) work, second driving mechanism (41) does not work.
Embodiment 2, at some chemical industry, under the use occasions such as rock gas, the truncating of medium fluid requires high, that is after valve closing, do not allow the situation occurring that any medium fluid is passed through, now, according to user demand, when damming, close the first driving mechanism (31) and the second driving mechanism (41), make the first driving mechanism (31) and the second driving mechanism (41) closed condition simultaneously, when opening stream, open the first driving mechanism (31) and the second driving mechanism (41) again, make the first driving mechanism (31) and the second driving mechanism (41) be in opening state simultaneously.
