Detailed Description
The invention is described in further detail below with reference to the drawings and the detailed description, but the invention is not limited to the scope of protection and application.
In the present embodiment, the first elastic member 204 and the second elastic member 303 are both springs.
Example 1
A dynamic regulation type oil pressure seat for preventing pressure overload in an oil field is shown in figures 1-4 and comprises an oil pressure seat body 1, an oil pressure gauge 2, a valve 3 and a dynamic regulation system; an oil pressure gauge 2 is arranged at the upper part of the oil pressure seat body 1; the lower part of the oil pressure seat body 1 is provided with a valve 3; a liquid inlet groove 1a, a first limiting groove 1b, a second limiting groove 1c and a pressure measuring groove 1d are sequentially formed in the oil pressure seat body 1 from bottom to top; the liquid inlet groove 1a, the first limiting groove 1b, the second limiting groove 1c and the pressure measuring groove 1d are communicated in sequence; dynamic adjusting systems are arranged in the first limiting groove 1b and the second limiting groove 1 c.
The dynamic adjusting system comprises a separating disc 201, a connecting column 202, a fixed disc 203, a first elastic element 204 and a top disc 205; a separating disc 201 is arranged in the first limiting groove 1 b; four connecting columns 202 are welded on the upper side of the separating disc 201; the four connecting columns 202 are arranged around the circumference at equal intervals; the upper sides of the four connecting columns 202 are welded with fixed disks 203; the middle part of the fixed disc 203 is provided with a through groove; six first elastic pieces 204 are connected to the upper side of the fixed disc 203; the six first elastic pieces 204 are arranged around the circumference at equal intervals; the upper sides of the six first elastic pieces 204 are connected with top discs 205; the middle part of the top disc 205 is provided with a through groove; the fixed disc 203, the first elastic piece 204 and the top disc 205 are all arranged in the second limiting groove 1 c; the first elastic element 204 and the top disc 205 are both in contact with the inner wall of the second limiting groove 1 c.
The diameter of the separating disc 201 is smaller than the inner diameter of the first limiting groove 1b and larger than the through hole above the first limiting groove 1 b.
When the dynamic regulation type oil pressure seat capable of preventing pressure overload for the oil field is used, the oil pressure seat body 1 is installed at a position where oil pressure needs to be measured, a worker opens the valve 3 to enable crude oil to flow into the oil pressure seat body 1, the crude oil enters from the liquid inlet groove 1a and then reaches the position of the first limiting groove 1b, the separation disc 201 is jacked up by the crude oil, the crude oil flows upwards through a gap between the separation disc 201 and the first limiting groove 1b due to the fact that the diameter of the separation disc 201 is smaller than the inner diameter of the first limiting groove 1b, the crude oil flows into the second limiting groove 1c through the penetrating grooves in the centers of the fixed disc 203 and the top disc 205, finally the crude oil flows into the pressure measuring groove 1d, and oil pressure is measured through the oil pressure gauge 2.
When the oil pressure suddenly rises, the separating disc 201 can float upwards in crude oil, the separating disc 201 drives the connecting column 202, the fixed disc 203, the first elastic element 204 and the top disc 205 to synchronously move upwards, when the oil pressure exceeds the limit value of the oil pressure gauge 2, the separating disc 201 floats upwards to be in contact with the inner upper wall of the first limiting groove 1b, because the diameter of the separating disc 201 is larger than the through hole above the first limiting groove 1b, the separating disc 201 seals the through hole above the first limiting groove 1b, the crude oil below can not enter the second limiting groove 1c, when the oil pressure exceeds the limit value of the oil pressure gauge 2, the input path of the crude oil is cut off, the overload operation of the oil pressure gauge 2 is prevented, when the separating disc 201 is in contact with the upper wall in the first limiting groove 1b, the top disc 205 is in contact with the upper wall in the second limiting groove 1c, and the first elastic element 204 is compressed, and because the oil pressure changes, the separating disc 201 can continuously float upwards and downwards in a reciprocating manner, by utilizing the elastic buffering action of the first elastic piece 204, the impact acting force of the separating disc 201 on the oil pressure seat body 1 in the floating process is reduced, the impact acting force of the top disc 205 on the oil pressure seat body 1 is also reduced, after the oil pressure is recovered, the bearing force borne by the separating disc 201 is reduced, the separating disc 201 automatically falls down, the crude oil flows into the second limiting groove 1c again, the quick response to the change of the oil pressure is realized, and the measurement work of the oil pressure is recovered while the oil pressure is recovered.
