Abstract
The utility model relates to an oil pressure device for oil-water wells and belongs to a device for measuring fluid pressure. The oil pressure device for the oil-water wells comprises a pressure gauge, a short connector and a self-closing valve, the self-closing valve comprises a cup-shaped seat with a bottom hole and a valve body, the cup-shaped seat is fixed in a pipeline, the lower portion of the valve body matches with an internal thread of the cup-shaped seat, the upper portion of the valve body matches with an internal thread of a pressing cap, an inverted-cone floating valve core is embedded on the lower portion of a center hole of the valve body, an ejector pin is inserted into the upper portion of the center hole, an upper handle of the ejector pin is sleeved into a cap hole of the pressing cap in a clamping manner, the upper handle extends out of the upper portion of the cap hole of the pressing cap to be connected with an internal thread of the short connector, and an upper opening of the short connector and the pressure gauge are in screw connection. A pressure guide channel is formed sequentially from the bottom hole of the cup-shaped seat to the center hole of the valve body, a center hole of the ejector pin at a downward moving state of the floating valve core and a center hole of the pressure gauge. The oil pressure device for the oil-water wells overcomes the defects of past various pressure-measuring connectors and is of a built-in needle valve structure and internally filled with anti-freezing engine oil, and the pressure gauge is directly communicated with measured pressure during pressure measurement, so that pressure transmission errors are avoided. Besides, the oil pressure device is directly welded on a wellhead pipeline and has the advantages of precise pressure measurement, convenience in use, low-temperature resistance, theft prevention, safety and reliability.
Description
Technical field
The utility model belongs to the device of measuring fluid pressure, relates to a kind of oil-water well oil gear specifically.
Background technology
Liquid in industry such as oil, the chemical industry delivery line need be sampled chemical examination usually to confirm its physicochemical characteristics; So that take appropriate measures; But present sampling jointing does not have antitheft, antifreeze function, particularly the cold winter in the north; If do not adopt antifreezing measures, bring very big difficulty can for sampling or admission datamation; And the disappearance of anti-theft feature not only causes damage to national wealth, has increased the business administration difficulty, also directly influences the ordinary production of enterprise.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and a kind of oil-water well oil gear is provided.
The oil-water well oil gear of the utility model; Be to constitute by tensimeter, short circuit head and self-closing valve; Described self-closing valve comprises that the handleless cup seat that has bottom outlet is fixed in the pipeline, the bottom of valve body and cup screw-internal thread fit of screw-internal thread fit, its top and the pressure cap of seat; The bottom setting-in back taper float valve core of the center pit of valve body; Thimble is inserted on the top of center pit, the last handle of thimble and the cap hole of pressure cap mutually cutting ferrule, stretch out top, pressure cap cap hole on handle be connected with the internal thread of short circuit head, the suitable for reading and pressure epiphase spiral shell of short circuit head links.From the bottom outlet of handleless cup seat successively to the center pit of valve body, to the float valve core the thimble of shifting state center pit, constitute the pilot passage to the tensimeter center pit.
As the further improvement of the utility model, oared segrne pii is arranged at the bottom of the center pit of valve body, and its reverse taper with the float valve core matches.
As the further improvement of the utility model, be provided with flexible gap between the lower platform of last handle and the upper mounting plate of valve body, the top of going up of the lower end of thimble and float valve core offsets.
The oil-water well oil gear of the utility model has been avoided the deficiency of various pressure measuring tie-ins in the past, adopts built-in needle valve structure, in fill non-congealable oil, during pressure measurement, tensimeter directly communicates with the institute measuring pressure, does not have the pressure conduction eror; PMU directly is welded on the well head pipeline, has that pressure measurement is accurate, easy to use, low temperature resistant, antitheft and a safe and reliable beneficial effect.
