Description
Technical Field
The utility model belongs to the technical field of annotate fat valve plugging device, a leaking stoppage plug valve is related to.
Background
Because the internal spring or the valve ball of the gas production resin injection valve is damaged, the resin injection valve cannot be closed, and air leakage is caused. The main control valve can be operated because the pressure of the casing head needs to be cut off. The traditional method for cutting off the pressure of the pressure casing head comprises two methods: firstly, the traditional well killing is high in cost and long in period, and secondly, the valve replacement under pressure is high in cost, so that the maintenance cost of a gas production tree is saved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a leaking stoppage plug valve has solved and has annotated the unable problem that leads to leaking gas of closing of fat valve.
The utility model adopts the technical scheme that the plugging plug valve comprises a valve body, wherein the valve body comprises a horizontal section and a vertical section, a valve rod is arranged in the valve body, one end of the valve rod extends out of the valve body and is connected with a handle, a gasket, a gland and a packing layer are sequentially sleeved on the valve rod from top to bottom, a channel is formed between the lower part of the valve rod and the horizontal section of the valve body, and an oil guide groove communicated with the channel is arranged on the valve body; the valve rod is provided with a through hole.
The utility model discloses a characteristics still lie in:
the outlet end of the oil guide groove is connected with an oil nozzle.
The inner wall of the horizontal section of the valve body is provided with a groove, and the other end of the valve rod extends into the groove.
Lead the oil groove and include two, two lead the oil groove and be located valve body vertical section end, valve body horizontal segment bottom respectively.
The packing layer is a fluororubber ring.
The utility model has the advantages that:
the utility model relates to a plugging plug valve, which is connected with the tail part of a grease injection valve, and can effectively prevent the air leakage of a pressure release valve under the condition of not changing the valve under pressure; meanwhile, the problem of air leakage caused by the fact that the grease injection valve cannot be closed is solved through the modes of valve rod leakage stoppage and oil sealing, and the sealing effect is further improved.
Drawings
Fig. 1 is a schematic structural view of a plugging plug valve of the present invention;
fig. 2 is a front view of the plugging plug valve of the present invention.
In the figure: 1. the valve comprises a valve body, a valve rod, a handle, a gasket, a gland, a packing layer, a channel, a nozzle, a guide oil groove, a through hole and a groove, wherein the valve body is 2, the valve rod is 3, the gasket is 4, the gland is 5, the packing layer is 6, the channel is 7, the nozzle is 8, the guide oil groove is 9, the through hole is.
Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a leaking stoppage plug valve, as shown in figure 1, including valve body 1, valve body 1 includes horizontal segment and vertical section, is provided with valve rod 2 in the valve body 1, and valve rod 2 stretches into the horizontal segment by the vertical section of valve body 1, and recess 11 has been seted up to the horizontal segment inner wall of valve body 1, and the other end of valve rod 2 stretches into in the recess 11, and valve rod 2 one end stretches out of valve body 1 and is connected with handle 3, and gasket 4, gland 5, packing layer 6 have been cup jointed in proper order to valve rod 2 top-down, form passageway 7 between valve rod 2 below and the horizontal segment of valve body 1, set up on the valve body 1 and lead oil groove 9 with the communication of passageway 7; the valve rod 2 is provided with a through hole 10.
The outlet end of the oil guide groove 9 is connected with an oil nozzle 8, the oil nozzle 8 is positioned outside the valve body 1, and the oil nozzle 8 is a one-way valve ball; lead oil groove 9 and include two, two lead oil groove 9 and are located valve body 1 vertical section end, valve body 1 horizontal segment bottom respectively.
Preferably, the packing layer 6 is a fluororubber ring.
The utility model relates to a use method of leaking stoppage plug valve as follows:
one end of the valve body 1 is connected with the tail part of the grease injection valve, and the other end is connected with the drainage tube; initially, the axis of the through hole 10 is parallel to the axis of the horizontal section of the valve body 1, gas enters the drainage tube through the through hole 10, when the grease injection valve cannot be closed, the rotating handle 3 drives the valve rod to rotate for 90 degrees, the axis of the through hole 10 is vertical to the axis of the horizontal section of the valve body 1, and the gas is blocked to finish plugging; grease is injected into the oil nozzle 8, enters the channel 7 through the oil guide groove 9, and lubricates and seals the channel 7.
Through the mode, the leaking stoppage plug valve is connected to the tail part of the grease injection valve, so that the leakage of the pressure release valve can be effectively prevented under the condition that the valve is replaced without pressure; meanwhile, the problem of air leakage caused by the fact that the grease injection valve cannot be closed is solved through the modes of valve rod leakage stoppage and oil sealing, and the sealing effect is further improved.
