Abstract
The utility model discloses a plug valve used for pipeline systems for conveying liquid and gas. The utility model is mainly composed of a valve body, sealing plugs and transmission mechanisms, wherein the sealing plugs are in a cylinder body shape, and each sealing plug is composed of a wedge-shaped valve core with via holes, and a sealing plate which is connected the wedge-shaped combining surface in a dovetail groove structure; annular sealing rings are arranged on the sealing plates. The utility model has the characteristics that the plug valve is easy to open and close, wear is reduced, the service life of the sealing rings is extended and universality is good. Common working pressure of the utility model can reach 1.6 MPa, and the utility model has especially good dual sealing ensuring properties.
Description
The utility model belongs to stopcock, particularly a kind of stopcock of easy keying.
Stopcock is a valve commonly used in gas, the liquid pipeline system.Its greatest problem is easy wearing and tearing, and sealed precision is not high, and operating life is low.
The purpose of this utility model is to provide a kind of improved efficient sealed stopcock, and it can improve sealability effectively, reduces wearing and tearing, increases the life-span of seal ring.
Efficient sealed stopcock of the present utility model, mainly form by valve body, sealing cock and driving mechanism, it is characterized in that said sealing cock is cylindrical shape, its port two side directions are provided with the sealing plate that the oat tail groove structure mode connects, and sealing plate is oblique downwards with the junction plane of spool, and spool is wedge shape, sealing cock top is provided with the end handle, end handle place is provided with Sealing, sealing plate cylindroid be provided with O-ring seal, said end handle is connected with driving mechanism and handwheel.
Said driving mechanism drives sealing cock lifting and rotates 90 ° of angles and carry out along the roller guide groove.
Said Sealing is the v-ring combination.
Technique effect of the present utility model shows: it is cylindrical 1. sealing cock, is convenient to processing, easily assembling; 2. in off position down, block the duct by sealing plate, carry out two way sealed with ring packing, the side direction sphenoid surface of spool moves down propelling and pushes down sealing plate is stable, can guarantee sealing effect; 3. when opening, will carry on the spool by screw-drive mechanism, sealing plate is loosened after, turn over 90 ° of angles again, port is aimed at the duct, valve is opened for it, the wearing and tearing of seal ring can be eased down to minimum level; 4. hold the sealing of shank position can prevent effectively that liquid from leaking from handle; 5. be applicable among the pipeline of various transfusions, gas transmission, so versatility is good.
Be illustrated below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
As shown in drawings, this stopcock is mainly by valve body 1, sealing cock 2, mounting flange 4, and the driving mechanism of connecting sleeve 5 and interior dress thereof and handwheel 7 formed, and the 6th, the bearing box of screw axis is established for reducing the resistance easy-to-operat, and the 8th, valve position indication, the 3rd, duct.Driving mechanism comprises the screw axis 12 and the screw rod cover 13 that screw flight cooperates that are driven by handwheel 7, and removable mounting and couples together by connecting pin 14 and end handle 15 in the sealing cock 2 in connecting sleeve 5.Driving screw axis when handwheel rotates changes, screw rod cover 13 with screw-thread fit moves with respect to screw axis 12 and connecting sleeve 5, for making this motion become the lifting straight line motion of sealing cock 2, so a roller 11 is set on its jacket wall, roller can be roller or ball, roller along set guide groove 9 upwards then with screw axis on turn over the guide groove 10 of 90 ° of radians near Transverse plane the groove position match, realize the switch control of handwheel to 90 ° of directions of cock.Sealing cock 2 is the garden cylindricality, two side directions of port 20, the ragged edge device has two sealing plates 21 of tiltedly splitting shape, sealing plate 21 inboards connect so that oat tail groove structure is movable with the interior downwards oblique junction planes of spool 19, dovetails 17 is along sliding in the groove, sealing plate is promoted with the core valve, on inwardly loosening when moving, loosen the back and create the switch condition for cock 2 half-twists.Said driving mechanism drives the spool lifting and rotates 90 ° of angles and carry out along roller guide groove 9 and 10.The 18th, O-ring seal, be inlaid in sealing plate on the cylindroid, the 16th, Sealing for v-ring combined type product, is used to prevent by the handwheel position to external leakage.The sealability of this product structure is better than common.
Present embodiment is with the spiral jacking, and the spool wedge is to pushing tow, sealing plate both sides roof pressure, and two way sealed adds the excellent sealing of cock end shank position, common working pressure can reach 1.6Mpa.And close to, jacking with right rotation, or left-handed loosening promotes, and turns to then and opens.Convenient and swift efficient.
