Detailed Description
The invention will be further described with reference to the following examples.
Example 1.
As shown in fig. 1-2, the liquid leakage preventing plunger for gas production by drainage of a gas well comprises a plunger body 1, a plunger head 2 is mounted on the plunger body 1, a high-pressure water pipe joint 3 is mounted in the top of the plunger head 2, a water outlet valve spring 4 is connected to the high-pressure water pipe joint 3, a water outlet valve seat 5 is connected to the top of the other end of the water outlet valve spring 4, and a water outlet plug 6 is mounted on the top of the water outlet valve seat 5.
This application produces the piston motion through the operation of plunger pump when using will wait to extract liquid suction to plunger body 1 in, at first through plunger head 2, flow into to inside through high pressure water pipe connector 3, internally mounted's outlet valve spring 4 with liquid pump income to outlet valve seat 5 in, by the temporary shutoff of outlet valve stopper 6 storage, wait to pump into liquid and get into to next region when reaching certain quality and handle.
The leak protection structure 8 of installation enables liquid and gets into wherein, and the leak protection sealing washer 10 of both ends installation enables liquid and prevents to permeate to the external world, and the aqua storage tank of both sides installation can cushion liquid effectively, prevents that pressure from too big causing the overflow, and raceway 12 that is used for the reposition of redundant personnel is installed to both sides, and raceway 12 installs and also can greatly increased seal in whole leak protection structure 8 is inside, prevents that liquid from spilling.
The upper joint 9 is internally provided with a water guide pipe 13, and the center of the upper joint 9 is sleeved with an elastic element 14.
The liquid enters the upper joint 9 through the plunger spring structure 7, and the elastic element 14 arranged in the upper joint 9 can enable the liquid to flow out more quickly, so that the efficiency of the whole plunger is improved.
The inside of the plunger spring device can increase the buffering force, and the piston movement of the integral plunger can be buffered when the inner spring 15 is compressed, so that the service life of the plunger is prolonged.
A buffer cushion 17 is arranged at the joint of the top of the inner spring 15 and the leakproof seal ring 10.
Because long-time application causes the friction between inside spring 15 and the leak protection sealing washer 10, consumes leak protection sealing washer 10 easily, makes leak protection sealing washer 10 appear the gap, leads to the leakproofness not good, and the blotter 17 of installation can reduce effectively in this application and wear and tear to the consumption of leak protection sealing washer 10, prevents that liquid from spilling.
The center of the water outlet valve seat 5 is provided with a cylindrical round limiting pin 18, and the water outlet valve spring 4 is matched with the cylindrical round limiting pin 18.
The round limiting pin 18 is inserted into the spring, so that the positions of the water outlet valve spring 4 and the round limiting pin 18 can be fixed more conveniently, and the integral structure is more stable.
In the production process, the liquid that flows through is stored and shunted through leak protection aqua storage tank 11 of the inside both sides installation of leak protection structure 8 and raceway 12 of installation on leak protection aqua storage tank 11, installs and prevents that liquid from spilling in inside both sides, and the connection position goes out more and has increased leak protection sealing washer 10, has increased the seal of plunger, has reduced the possibility of leaking, can be safe convenient carry out drainage gas production operation more.
It should be finally noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.
