Abstract
Disclosed is a hydraulic valve with a pressure measuring interface; a small controllable unidirectional valve is arranged in the valve body of the hydraulic valve; under the general state, the valve core conical surface of the unidirectional valve seals the valve base hole to avoid the pressure oil from leaking. When the pressure measurement is required, a soft pipe joint connected with a pressure meter is mounted in a threaded hole; the valve body in the center of the soft pipe joint jacks up the valve core of the unidirectional valve to enable the pressure to flow to the pressure meter through the gap of the valve core for measuring the pressure value. When the measurement is finished, the soft pipe joint is demounted; the valve core of the unidirectional valve projects upwards under the effect of a spring and the pressure oil; the conical surface of the valve core seals the valve base hole to realize the automatic sealing and avoid the liquid in the pipeline from losing. The hydraulic valve with a pressure measuring interface not only can have the effect of a common hydraulic valve, but also can measure the pressure of the position of the hydraulic system conveniently and have the advantages of simple structure, low cost, realizing the generality and standardization easily.
Description
Technical field
The utility model relates to hydrovalve, especially has the hydrovalve 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 hydrovalve in the hydraulic system at present, be controlling party to the element of, flow and pressure, the interface that does not have measuring pressure on it, 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 hydrovalve not with the defective of pressure measurement interface, a kind of general hydrovalve 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.
The technological scheme that its technical problem that solves the utility model adopts is:
A little controllable check valve is set on the valve body of hydrovalve, 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, protective hat 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 protective hat that common hydrovalve is the same uses with other.
The beneficial effects of the utility model are, this hydrovalve that has the pressure measurement interface not only can play the effect of common hydrovalve, the force value of this part of measuring system easily, be equivalent to open the window that to spy 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 little controllable check valve is installed in the tapped hole of the valve body 1 of directional control valve, pressure valve, Flow valve, 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, protective hat 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 the cross recess b and core body 8 endoporus on the gap between spool 2 and the valve seat 5, spool 2 tops.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 protective hat is the harm that protection one-way valve and tapped hole are not subjected to other object strikes and dust.
Characteristics of the present utility model are to make at the measurement interface of the hydraulic valve of all size With same screwed hole and check valve, can connect various with a cover Pressure gauge hose joint This hydraulic valve with interface of pressure measurement of equipment, both easy, save again cost.
