Abstract
The utility model provides a hollow water distributor, comprising an upper connecting pipe, a middle connecting pipe, a lower connecting pipe, a distribution of water core, a sealing ring, a plane buckle inner joint, a spring, an outer connecting pipe, a valve seat, distribution of water holes, a lower connecting joint, and a valve body. Sliding bushes are respectively arranged on the upper connecting pipe and the lower joint; an oil seal core is arranged between the sliding bushes and the distribution of water core; the oil seal core is fixed on the sliding bushes. The utility model is a hollow water distributor which has good sealing, and the sealing ring of the hollow water distributor cannot brush off.
Description
Technical field: the utility model relates to the hollow distributor that a kind of water injection well is used.
Background technology: at present, hollow distributor, water distributing core band sealing ring, sealing ring easily comes off when throwing fuse, and the sealing ring after coming off very easily falls in the well, influences other operation.
Summary of the invention: in order to address the above problem, the utility model provides a kind of good seal, the adeciduate hollow distributor of sealing ring.
Concrete technical scheme is as follows: a kind of hollow distributor, comprise that top adapter, middle part adapter, bottom adapter, water distributing core, sealing ring, flat buckle spigot, spring, extension tube attached, valve seat, distributing hole, lower contact, valve body, it is characterized in that: in top adapter and lower contact, be respectively equipped with sliding sleeve, be provided with the oil sealing fuse between sliding sleeve and water distributing core, the oil sealing fuse is fixed on the sliding sleeve.
Compare with prior art, the utility model adopts said structure, has changed the structure of water distributing core band sealing ring in the past, and the sealing of the utility model water distributing core realizes sealing by the oil sealing fuse of sulfuration on sliding sleeve, can guarantee sealing, sealing ring is come off.
Description of drawings: the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
The specific embodiment: as shown in Figure 1, a kind of hollow distributor, top take over 5 and on flat button spigot 1 connect by tubing thread, outside flat button spigot 1, be connected with and regulate box cupling 2, spring plain cushion 3 is enclosed within top and takes on 5, in the adapter of top, spring plain cushion 3 lower end, be provided with spring 4, top is taken over 5 and is connected by screw thread 14 with extension tube attached 6,10 of extension tube attached and valve seats are provided with sealing ring 9, extension tube attached 6 and middle part are taken over 11 and are connected by screw thread 14, the middle part is taken over 11 and is provided with distributing hole 20, the middle part is taken over 11 and is connected by screw thread 14 with bottom adapter 16, middle part adapter 11 and bottom are taken over 16 and are provided with sealing ring 15, the bottom is taken over 16 and is connected by screw thread 14 with lower contact 18, the bottom is taken over 16 and is connected by screw thread 14 with valve body 12, bottom adapter 16 and 12 of valve bodies are provided with sealing ring 13, in top adapter 5 and lower contact 18, be respectively equipped with sliding sleeve 17,19 of sliding sleeve 17 and water distributing core are provided with oil sealing fuse 7,7 sulfurations of oil sealing fuse are on sliding sleeve 17, and water distributing core can be faucet type water distributing core and dead mouth formula water distributing core.
Operating principle: drop into water distributing core (stagnant water mouth) from well head, suppress from oil pipe, packer expands and seals, and expanding is honored as a queen pulls water distributing core out, drop into the water distributing core water distribution again after adjusting water nozzle, the sealing of water distributing core realizes sealing by the oil sealing fuse on the sliding sleeve, can guarantee sealing, and sealing ring is come off, it is up that water promotes valve seat, the compression spring, valve seat and valve body form the gap, realize water distribution.
