Description of drawings

Fig. 1 is the stifled structure diagram that send the instrument of getting of a kind of novel V-R of the utility model.

The specific embodiment

Below in conjunction with Fig. 1 the utility model is further elaborated.

As shown in Figure 1, the stifled instrument of getting that send of a kind of novel V-R, comprise handwheel 1, piston connecting rod parts 2, oil cylinder 11, connector 15, first stop valve 4, second stop valve 14, sleeve 16, in conjunction with flange 17, piston connecting rod parts 2 is arranged on the inside of oil cylinder 11, one end is connected with handwheel 1, and its other end links to each other with sleeve 16; The two ends of oil cylinder 11 are respectively arranged with oil cylinder head 5 and connector 15; Be arranged on the connector 15 in conjunction with flange 17, first stop valve 4 and second stop valve 14 are separately positioned on oil cylinder head 5 and the connector 15, link to each other by oil pipe 12, oil pipe 12 links to each other by the high pressure screw thread with first stop valve 4, second stop valve 14, is connected by 60 ° of taper pipe threads between second stop valve 14 and the connector 15; Piston connecting rod parts 2 comprises first piston 211, second piston 212 and piston rod 22; Tighten with screw thread between the first piston 211 and second piston 212, and coat screw thread fastening glue, piston rod 22 is made as two sections, and one section links to each other with first piston 211, and another section links to each other with second piston 212; Sleeve 16 inside are provided with interior hexagonal structure, and are suitable with stifled 19 profiles of V-R; This V-R is stifled to send the instrument of getting also to comprise a pair of locking nut 13, and a pair of locking nut 13 is arranged on the outside of oil cylinder 11, contacts with oil cylinder head 5, connector 15 respectively, is used for locking cylinder head 5 and connector 15.

The stifled instrument of getting that send of a kind of novel V-R utilizes " fluid cylinder pressure balance " principle, and the opening and closing by first stop valve 4 and second stop valve 14 come regulating piston parts 21 both sides area pressure differences to come work.Oil cylinder head 5 is respectively equipped with sealing ring 3, sealing ring 9 and sealing ring 10 with connecting portion, the piston rod 22 of oil cylinder 11 with the connecting portion of connector 15 with connecting portion, the piston element 2 of piston rod 22, guarantee overall sealing performance, piston element 21 has adopted key cover 7 to be connected with piston rod 22, not only satisfied big shearing force requirement under the high pressure, piston rod 22 can be made of polished rod simultaneously, has saved material and has reduced processing cost.

As shown in Figure 1, the utility model was installed V-R at stifled 19 o'clock, V-R stifled 19 is installed on the interior hexagonal of sleeve 16, makes in conjunction with flange 17 by bolt and nut to be connected on the gate valve flange 18, open gate valve, slowly open second stop valve 14, the two sides of piston element 21 forms pressure differential, promotes piston rod 22 under the effect of pressure, and V-R stifled 19 is delivered to the position that needs setting, clockwise rotate handwheel 1, make V-R stifled 19 recognize button.After recognizing button, handwheel 1 14 ~ 15 circles that continue to turn clockwise tighten for several times repeatedly, guarantee that V-R stifled 19 tightens and seals, and open first stop valve 4, and fluid flows out from plug hole, release pressure; Handwheel 1 is pulled back, the stifled instrument of getting and the V-R stifled 19 of sending of V-R broken away from, pull down valve and V-R stifled 19 and send the instrument of getting, check the shutoff situation.

The utility model was pulled down V-R at stifled 19 o'clock, V-R is blocked up send being installed on the gate valve flange 18 in conjunction with flange 17 of the instrument of getting, and opened second stop valve 14, promoted piston rod 22 to V-R forward and blocked up 19, made V-R stifled 19 stuck with the interior hexagonal of sleeve 16; Slowly rotation hand wheel 1 to V-R stifled 19 is all loose intact counterclockwise, and this moment, V-R stifled 19 was trapped in conjunction with the aperture because of the pressure differential of piston element 21 both sides, slow first stop valve 4 that opens, can stretch out automatically until piston rod 22, and control screw nut 13, impel piston rod 22 slowly to rise.When piston rod 22 extends the limit, closing gate valve is pulled down the stifled instrument of V-R, and it is stifled 19 to take off V-R, and scrub and wear well are kept properly for future use.

Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
