Abstract
The utility model relates to a pressure gauge used for oil and gas gathering and transferring, in particular to an environmentally-friendly pressure gauge joint. The technical schemes in the utility model are as follows: the environmentally-friendly pressure gauge joint includes a pressure gauge, a pressure gauge joint and a valve device; the valve device is arranged inside the pressure gauge joint; an oil and gas passage passes through the valve device; the valve device is composed of a tapered sealing seat and a valve ball; the movable valve ball is arranged inside the tapered sealing seat; the valve ball is sealed with the tapered sealing seat; the upper part of the pressure gauge joint is connected with the pressure gauge through an internal screw thread; and the lower end of the pressure gauge joint is provided with an outer screw thread. The environmentally-friendly pressure gauge joint of the utility model is advantageous in simple structure, low cost, and convenient installation and maintenance. The environmentally-friendly pressure gauge joint further has the following advantages that: when a connected accessory body is broken, a needle valve can be automatically closed from a normally-open state, such that environmental accidents can be effectively prevented; the valve ball is made of non-metal materials with excellent toughness and corrosion resistance, when being squeezed to a top portion hole shrinkage position, the valve ball can be deformed elastically according to a contact surface, such that excellent sealing can be realized.
Description
Technical field
The utility model relates to a kind of oil-gas gathering and transportation tensimeter, particularly a kind of environmental protection pressure meter connector.
Background technology
At present the needle-valve on the oil-gas gathering and transferring technology flow process mainly contains two kinds of functions: a kind of is the sampling cock, and state is normally closed, another kind ofly connects equipment or the line pressure table of measured medium by pressure tapping, and state is often opened.Tensimeter is a weak link on the flow process as the annex on the oil-gas gathering and transferring technology flow process, in case windage loss, damage by water or other collision situations occur, the tensimeter cracky, the flow process oil and gas leakage, contaminated environment affects the oil field and normally produces.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of environmental protection pressure meter connector is provided, and needle-valve can effectively be avoided the environmental protection accident from the normally open autoshutdown.
Its technical scheme is: comprise tensimeter, pressure tapping and faner apparatus, described pressure tapping inside is provided with faner apparatus, gas channel is through faner apparatus, described faner apparatus is comprised of conical sealing seat, valve ball, conical sealing seat inside is provided with movable valve ball, and valve ball and conical sealing seat are realized sealing; Pressure tapping top is connected with tensimeter by internal thread; The lower end of pressure tapping is provided with external thread.
When the tensimeter connection was excellent, valve ball did not affect normal pressure transmission passage because deadweight drops on the entrance point bottom, can normally read pressure from tensimeter.Cause when leaking when tensimeter is impaired, valve ball is pulled to pars intermedia conical sealing seat position on the faner apparatus under the effect of oil gas pressure reduction, play sealing function, and the hydrocarbon flow passage is ended.
The beneficial effects of the utility model are: (1) is simple in structure, and cost is low, makes things convenient for I﹠M; (2) when the attachment body that connects was damaged, needle-valve can effectively be avoided the environmental protection accident from the normally open autoshutdown; (3) valve ball is preferably nonmetallic materials (anticorrosion) making of toughness, when being extruded into undergauge position, top, can according to surface of contact generation elastic deformation, reach excellent sealing.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: tensimeter 1, pressure tapping 2, faner apparatus 3, conical sealing seat 4, valve ball 5, external thread 6, internal thread 7.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises tensimeter 1, pressure tapping 2 and faner apparatus 3, described pressure tapping 2 inside are provided with faner apparatus 3, gas channel is through faner apparatus 3, described faner apparatus 3 is comprised of conical sealing seat 4, valve ball 5, conical sealing seat 4 inside are provided with movable valve ball 5, and valve ball and conical sealing seat are realized sealing; Pressure tapping 2 tops are connected with tensimeter 1 by internal thread 7; The lower end of pressure tapping 2 is provided with external thread 6.
Principle of work: the tensimeter of installing in the Oil-Gas Gathering Technology flow process, after opening needle valve, pipeline internal medium enter the pressure tapping entrance point extended the aperture in, valve ball drops on the entrance point bottom because of deadweight, do not affect normal pressure transmission passage, can normally read pipeline pressure, grasp pressure changing in order in time understand, lay the foundation for analyzing various faults.If tensimeter damages when causing oil and gas leakage, valve ball is pulled to pars intermedia conical sealing seat position on the faner apparatus under the effect of oil gas pressure reduction, play sealing function, and the hydrocarbon flow passage is ended, be equivalent to needle-valve from the normally open autoshutdown, can effectively avoid the generation of environmental protection accident.
