Abstract
The utility model belongs to a pipeline pressure control valve, in particular to an automatic pressure regulating valve which can be used for various liquid central conveyance pipelines, avoid pressure fluctuation, ensure balance conveyance and protect instruments and meters in the conveyance pipelines from being damaged by pressure influence. The automatic pressure regulating valve comprises a valve body, wherein the valve body is internally provided with a liquid flowing channel and an outlet pressure liquid trough which is communicated with a valve body central hole; a seal cover is connected with the valve body; a pressure regulating type valve plug is arranged in the seal cover; and the conveyance pressure in pipelines is automatically regulated by utilizing the pressure regulating type valve plug. The automatic pressure regulating valve is simple in structure and easy to manufacture, can ensure the stability of the conveyance pressure in pipelines and the normal of the conveyance capability, can be used in various liquid conveyance pipelines, reduce the influence to the instruments and the meters in various conveyance pipelines, prolong overhaul period and service life and reduce cost loss; and the automatic pressure regulating valve can automatically regulate pressure, obviously simplify operation procedure and lowers the labor intensity of workers.
Description
Technical field
The utility model relates to the pipeline pressure control valve, and particularly a kind of automatic pressure regulator can be used for avoiding pressure surge in the various liquid collector and delivery pipes road, and balance is carried, the instrument and apparatus in the protection collector and delivery pipe road be not stressed fluctuation influence and damage.
Background technique
The oil field is to utilize the pipeline common valve to the control mode of various gathering line pressure at present, and the size of regulating its opening degree refluxes, the pressure release operation.But because the difference of various gathering line operating conditions, in case pressure moment occurs than great fluctuation process, changing will appear in pressure and flow.The normal operation of influence on the one hand also can bring harmful effect to the various instruments, the instrument that are installed on the pipeline on the other hand, also can cause the equipment instrument when serious and damage pipeline overpressure failure accident.Valve is changed in on-the-spot decompression through in various degree, increases pressure gauge range etc. and does not all reach desirable effect, and wasted cost.The pressure of gathering line is regulated frequent, loaded down with trivial details.If utilize frequency conversion equipment to carry, its equipment price is expensive, cost is high.The scene needs a kind of inexpensive, effective stable-pressure device.
Summary of the invention
The purpose of this utility model provides a kind of automatic pressure regulator, overcomes above-mentioned technological deficiency, makes it possess good stable, can guarantee the steady of pressure, does not also influence flow, simplifies procedures.Reduce expenses such as meter calibration, check, reduce production costs.
The purpose of this utility model is achieved in that a kind of automatic pressure regulator comprises valve body, be provided with liquid chunnel in the valve body, also be provided with the logical liquid bath of the outlet pressure that connects with the valve body center hole in the valve body, seal closure is connected with valve body, the pressure regulating type spool is housed in seal closure, utilizes the pressure regulating type spool to regulate the interior discharge pressure of pipeline automatically.
Use the utlity model has following useful effect and tangible advantage:
1, the utility model can guarantee that pipeline delivery pressure steadily and conveying capacity normal, can in multiple fluid-carrying lines, use, can weaken the effect, prolong turn(a)round the instrument in the multiple transfer line, instrument, increase the service life, loss reduces cost;
2, this device automatic pressure regulation has significantly been simplified programmed sequence of operations, has reduced working strength of workers;
3, the utility model is simple in structure, and is easy to manufacture, with low cost, convenience quick for installation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, a kind of automatic pressure regulator comprises valve body, be provided with liquid chunnel in the valve body, also be provided with the logical liquid bath 7 of the outlet pressure that connects with the valve body center hole in the valve body, seal closure 9 is connected with valve body, the pressure regulating type spool is housed in seal closure 9, regulates the hydrodynamic pressure of the present utility model of flowing through automatically by the pressure regulating type spool.The pressure regulating type spool comprises center-pole 1, pressure adjusting spring 2 and pressure regulating ring 3, and the bottom of center-pole 1 is provided with logical liquid bath 6, and pressure adjusting spring 2 is installed between seal closure 9 and the pressure regulating ring 3.Logical liquid bath 6 is vee gutters, and its gradient selects 1: 40-1: any one size between 60, as 1: 45,1: 55 etc.; The external diameter of pressure regulating ring 3 is greater than the diameter of valve body center hole.The logical liquid bath 7 of outlet pressure connects with it in the bottom of valve body center hole and is communicated with the outlet end of liquid chunnel, and the side of the logical liquid bath 7 of outlet pressure is in communication with the outside, and sealing bolt 8 is housed, the easy cleaning sediments.The periphery of valve body center hole is provided with the seal ring mounting groove below seal closure 9, built-in ring 4.Entrance point and outlet end welded flange 5 in the valve body both sides are fixed to the use position by the bolt on the flange with this device, and the pressure regulating type spool will carry out the adjusting of flow pressure according to the setting of pressure, and is simple to operate.At first according to service condition, the pressure regulating ring 3 of this device is turned the size of regulated fluid pressure up or down.
Fluid in pipeline is by import of the present utility model, when the logical liquid bath 6 of center-pole 1 enters outlet, under the effect of the logical liquid bath 7 of outlet pressure, pressure is directed to the bottom of center-pole 1, under the effect of pressure, center-pole 1 moves up, and the logical liquid measure of logical liquid bath 6 reduces, and outlet pressure reduces.When outlet pressure reaches setting pressure, center-pole 1 logical liquid bath 6 on close after moving to the top of seal ring 4.Treat that pressure reduces the back under the effect of pressure adjusting spring 2 pressure, center-pole 1 moves down opens logical liquid bath 6, reaches the self-regulating purpose of pressure.The valve body two ends flange 5 of burn-oning is linked in the gathering line with the flange ways of connecting.
