A flange-type gauge valve group comprises a communicating needle valve, an emptying needle valve and a valve group body, wherein the valve group body is cylindrical; round grooves are formed in centers of the upper top surface and the lower bottom surface respectively; the emptying needle valve is arranged in the middle of the front side of a central line; an emptying hole is horizontally formed in a peripheral surface from the bottom to the right side of a needle point hole of a valve seat; the communicating needle valve is arranged in the middle of the left side in a horizontally inward manner; a communication hole is formed in a position from the upper peripheral side of the needle point hole of the valve seat to an upper part of the bottom of the upper round groove; a communication hole is formed in a position from the communication hole to the peripheral side of the needle point hole of the emptying needle valve seat; and a communication hole is formed in a position from the lower peripheral side of the needle point hole of the valve seat to an upper part of the bottom of the lower round groove. Annular bosses are arranged on the circumferences of the upper and lower round grooves; a seal steel ring groove is formed in the upper annular boss or the lower annular boss, bolt holes are formed in the circumferences of the annular bosses; or a screw thread interface provided with a female thread is arranged in the upper annular boss or the lower annular boss; or a weld nipple is welded on the circumference of the lower round groove.
Description
Technical field
The present invention relates to a kind of flange-type Gauge Valves group that connects instrument, solve existing Gauge Valves group due to unreasonable structure, flexible connection face is many, and leakage point is many, causes sealing unreliable, the problem that the instrument to collect data are inaccurate.
Background technique
All adopt at present automatic management in oil-gas gathering and transportation system, the installation requirement of pressure transmitter pressure transducer and intelligent manometer is very high, a bit leakage can not be arranged, otherwise will affect the control of automation, unreasonable due to existing valve block structure, junction surface is many, leakage point reaches the connection more complicated more, installing space is little in addition, does not leak very difficult assurance joint, present oil-gas gathering and transportation control flow is all compact, various instrument are installed many, existing Gauge Valves group has been not suitable with the requirement of automation control flow.
Summary of the invention
The objective of the invention is a kind of flange-type Gauge Valves group, overcome the defective that above-mentioned prior art exists, satisfy the requirement that automation is controlled.
Technological scheme of the present invention is achieved in the following ways:
The present invention includes and be communicated with needle type valve, emptying needle type valve, valve group body, it is characterized in that valve group body is made as cylindrical, be provided with separately a circular groove at upper end face and bottom surface center, be provided with an emptying needle type valve at middle part, center line front side to front side face middle part, be provided with a relieving device in bottom, needle point hole to the right side side face level of emptying needle valve seat; Left side central portion level at valve group body inwardly is provided with a connection needle type valve, top, the end at the supreme circular groove of needle point hole side last week of needle valve seat is provided with an intercommunicating pore, intercommunicating pore to all sides in the needle point hole of emptying needle valve seat are provided with an intercommunicating pore, are provided with an intercommunicating pore on the lower periphery side in the needle point hole of needle valve seat to the top, the end of lower circular groove; Be provided with an annular boss in up and down circular groove periphery, be provided with the sealing steel rings groove on upper annular boss or on lower annular boss, periphery at annular boss is provided with bolt hole, or at the screw thread interface that is provided with on upper annular boss or on lower annular boss with box thread, or at welding pipe nipple of lower circular groove periphery welding.
Flange-type Gauge Valves group and pressure gauge or pressure transmitter or pressure sensor interface flange are connected or are threaded.
Flange-type Gauge Valves group is connected with a year pressure pipeline flange or is threaded or welds by the welding pipe nipple.
Compared with the prior art the present invention has the following advantages:
1, the present invention is made as integral type to the attachment portion of connecting valve and atmospheric valve and pressure line, connecting link and leakage face have been reduced, compressed the operating space, can guarantee the sealing reliability of junction surface, guarantee the operating accuracy of pressure gauge, pressure transmitter and pressure transducer, guaranteed the reliability of automation.
2, the Placement variation can extensively adapt to on-the-spot actual requirement.
3, can form in conjunction with on-the-spot actual requirement the seriation of product.
