Abstract
The utility model relates to a pipe coupling provided with a pressure measurement interface. A small controllable check valve is arranged inside the coupling. Under normal conditions, a tapered surface of a valve core seals up a valve seat hole to prevent the pressure oil from leaking. When measuring the pressure, a flexible pipe coupling provided with the pressure measurement interface is arranged into a threaded hole. A core body in the flexible pipe coupling pushes the valve core of the check valve out to make the pressure oil flow into the manometer through a clearance of the valve core so as to measure pressure. After measuring the pressure, the flexible pipe coupling is demounted. The valve core of the check valve pushes upwards under the action of a spring and the pressure oil, of which the tapered surface seals up the valve seat hole; thereby the self-sealing is realized to avoid leakage of the liquid inside the pipeline. The pipe coupling provided with the pressure measurement interface not only plays the role in connection of the ordinary pipe coupling, but also is used conveniently for measuring the pressure of every part in a system. Because of the simple structure and the low cost, it is easy to realize the universalization and standardization.
Description
Technical field
The utility model relates to hydraulic fitting, especially has the pipe joint of pressure measurement interface.
Background technique
In hydraulic system debugging and trouble shooting process, understand each several part in the system force value be very important, be applied to the pipe joint in the hydraulic system at present, it is the element that connection oil pipe and other hydraulic element become path, the interface that does not have measuring pressure on it, other common hydraulic element are not with the measurement interface yet, have only a fixing measuring point in the general hydraulic system, other parts can not measured pressure value, makes very difficulty of hydraulic system debugging and trouble shooting.
Summary of the invention
In order to overcome existing pipe joint not with the defective of pressure measurement interface, a kind of general pipe joint that has the pressure measurement interface is provided, also can measure the force value of each several part when making the hydraulic system running easily, for system's adjustment and fault judgement provide foundation.
This technological scheme of using novel its technical problem of solution to be adopted is:
A little controllable check valve is set on the fittings body of pipe joint, and under normal conditions, the spool conical surface of one-way valve is sealed valve seat orifice can not leak pressure oil.When the needs measuring pressure, dust cap is taken off from tapped hole, pack in the tapped hole being connected with manometric hose coupling, the core body at hose coupling center backs down the spool of one-way valve, make pressure oil flow to pressure gauge, measured pressure value by the gap of spool and valve seat and the cross recess on spool top.Simultaneously, the seal ring of core body end compresses the valve seat end, makes the pressure oil can not be to external leakage.Measuring pressure finishes, and unloads hose coupling, the spool of one-way valve jack-up upwards under the effect of spring and pressure oil, and the conical surface on it is sealed valve seat orifice, and fluid can not be leaked, and loads onto behind the dust cap that the common tube joint is the same uses with other.
The beneficial effects of the utility model are, this pipe joint that has the pressure measurement interface not only can play the interconnect function of common tube joint, the force value of measuring system each several part easily, be equivalent to open a plurality of windows of spying on, make the debugging of system and faut detection very convenient to the hydraulic system of sealing.After hose coupling unloads, can seal voluntarily, the liquid that can not in the pipeline runs off.And simple in structure, cost is low, realizes generalization and standardization easily.

Embodiment
As shown in the figure, a controllable check valve is installed in six sides' the tapped hole outside the fittings body 1 of FERRULETYPE, welding type, flared fitting, the conical surface of the spool 2 of one-way valve is towards the endoporus of valve seat 5, spring 3 is equipped with in the bottom of spool 2, the seal ring 4 of valve seat 5 lower ends is pressed on the interior edge face of tapped hole, prevents that pressure oil from leaking.When the needs measuring pressure, dust cap 13 is taken off from tapped hole, the hose coupling 7 that is connected with pressure gauge 12 is packed in the original thread hole, the core body 8 at hose coupling 7 centers backs down the spool 2 of one-way valve, make between spool 2 and the valve seat 5 and produce the gap, pressure oil flows to pressure gauge, measured pressure value by 2 ones cross recess b and core body 8 endoporus on the gap between spool 2 and the valve seat 5, the spool.Simultaneously, the seal ring 6 of core body 8 ends is pressed on the upper-end surface of valve seat 5, makes the pressure oil can not be to external leakage.Clip 9 is pressed on flexible pipe 10 on the cylindrical on core body 8 tops, and cylindrical is provided with several circular groove c, can make to connect reliably.The upper end of handgrip 11 is threaded with pressure gauge 12, lower end and flexible pipe 10 clip connecteds, and the material of flexible pipe 10 adopts the braided steel wire rubber hose, is convenient to observe pressure gauge numerical value.
Measuring pressure finishes, and unloads hose coupling, spool jack-up upwards under the effect of spring and pressure oil, and the conical surface on it is sealed valve seat orifice, and fluid can not be leaked, and the effect of dust cap is the harm that protection one-way valve and tapped hole are not subjected to other object strikes and dust.
Fig. 6 another embodiment shown in being is illustrated in the position that this measurement interface is set on the radial type pipe coupling, spool 2, and spring 3, valve seat 5, hose coupling 7, core body 8 is installed in the tapped hole in the hinged hex head bolt 14 top hexahedrons successively.
Characteristics of the present utility model are to use on the measurement interface of the pipe joint of all size with a kind of tapped hole and one-way valve, this pipe joint that has the pressure measurement interface that can connect various device with a cover pressure gauge hose coupling device, both easy, save cost again.
