Abstract
The utility model relates to a valve body, which can obstruct any fluid and is composed of a valve body, a valve seat, a valve cap with a valve handle, a sealing device arranged on valve handle but arranged in valve cap, valve core fixed at lower end of valve handle and handwheel positioned at upper end of valve handle. In addition, the valve comprises an auxiliary valve on one side of valve, thus forming main valve and auxiliary valve, of which auxiliary valve has valve cap. A auxiliary valve gantry is arranged on valve cap. An auxiliary valve handle is arranged in the center of gantry, which connects with the auxiliary valve through auxiliary valve cap. End of auxiliary valve handle in auxiliary valve is provided with auxiliary valve flashboard. Auxiliary valve handle forms a slanting angle with vertical main valve handle. The utility model can cut off the fluid flowing into and out of flow passage and realize repair under pressure, in particular to the working conditions of high-temperature and medium-pressure corrosive fluid in petrochemical industry. The proposed installation angle of the valve is 40o-45o. Therefore, the utility model has solved crowded and disordered pipe collocation and makes pipe ranking easy and convenient, which occupies less cubage and has the advantages of rational layout.
Description
Technical field
The utility model relates to valve, the particularly a kind of valve that can stop fluid arbitrarily.
Background technique
Existing stop valve or membrane valve are to realize allowing pressurized maintenance by the fluid that unidirectional cut-out enters runner, especially the application of the corrosive fluid of in the petrochemical industry field, pressing in the high temperature, but need to adopt stop valve or the membrane valve that is suitable for the allowing pressurized maintenance of hydraulic fluid operating conditions in the high temperature.Although in above-mentioned application stop valve or membrane valve have been installed, it only limits to setting angle about 90 °, and can not adapt to the installation of other angle, and it is crowded and numerous and diverse to cause fluid line to be arranged, nor can stop fluid with other angle.
Summary of the invention
Task of the present utility model provides a kind of improved valve that can stop fluid arbitrarily, the setting angle that it has solved existing stop valve or membrane valve only limits to 90 °, it is crowded and numerous and diverse to cause fluid line to be arranged, and can not stop the problem of fluid with other angle.
The technical solution of the utility model is as follows:
A kind of valve that can stop fluid arbitrarily, it comprises valve body and valve seat, the valve gap of valve rod is housed, be placed in the seal arrangement that is positioned at valve gap on the valve rod, and spool that is connected with the valve rod lower end and the handwheel that is installed in the valve rod upper end, it also comprises the secondary valve that is installed in valve body one side, forms main valve and secondary valve; Described secondary valve is equipped with secondary valve gap, and secondary valve portal frame is housed on secondary valve gap, installing one auxiliary valve rod in the middle of secondary valve portal frame, and this auxiliary valve rod passes secondary valve gap and enters secondary valve inside, settles secondary valve flashboard in the auxiliary valve rod end that is positioned at secondary valve inside; Form included angle between the main valve stem of the auxiliary valve rod of described secondary valve and the main valve of positioned vertical with angle.
The valve that can stop fluid arbitrarily of the present utility model can cut off the fluid that enters and discharge runner at work, realizes allowing pressurized maintenance, is particluarly suitable for using under the operating conditions of pressure corrosive fluid in the high temperature in the petrochemical industry.Because this valve is suitable for installing under setting angle is about 40 °～45 ° operating conditions, has therefore overcome crowded, the numerous and diverse phenomenon of conduit arrangements in the arrangement of pipeline, makes conduit arrangements simple, volume-diminished is rationally distributed.
Valve mechanism of the present utility model is simple, and is easy to operate, is installed in the pipeline and can stops fluid arbitrarily, guaranteed the safety reliability of allowing pressurized maintenance, enlarged the application area of valve.
Description of drawings
Accompanying drawing is a kind of structural representation that can stop Fluid valve arbitrarily of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of valve that can stop fluid arbitrarily of the present utility model is equipped with main valve and secondary valve.Main valve body 1, main valve seat 2 and main valve lid 3 are housed on the main valve, on the main valve lid 3 main valve stem 4 are housed, on main valve stem 4, be positioned at the seal arrangement 5 in the main valve lid 3.Sealing device 5 is equipped with seal 51 and sealing trim ring 52, and sealing trim ring 52 is pressed and put on seal 51, and seal arrangement 5 is connected on the main valve stem 4 by link.Dispose a main valve plug 6 in the lower end of main valve stem 4, then settle a handwheel 7 in the upper end of main valve stem 4.
Secondary valve is installed in a side of main valve body 1.On the secondary valve secondary valve gap 8 is housed, the secondary valve portal frame 9 of assembling on secondary valve gap 8, installing one auxiliary valve rod 10 in the middle of secondary valve portal frame 9.This auxiliary valve rod 10 passes secondary valve gap 8 and enters secondary valve inside, connects in auxiliary valve rod 10 ends that are positioned at secondary valve inside and settles secondary valve flashboard 11.Settle a secondary valve hand wheel 12 in auxiliary valve rod 10 upper ends.Operate secondary valve hand wheel 12, make auxiliary valve rod 10 half-twists can open or close secondary valve flashboard 11.
Form included angle between the main valve stem 4 of the auxiliary valve rod 10 of secondary valve of the present utility model and the main valve of positioned vertical with angle.Angle angle between this auxiliary valve rod 10 and the main valve stem 4 is generally 40 °, also can be 45 °.But reduced volume just when arranging pipeline like this overcomes the crowding phenomenon of conduit arrangements, makes layout more reasonable.
Claims (4)
