Abstract
The utility model relates to an adjustable type throttling valve which is characterized in that a valve joint is provided with an adjusting screw rod inside. One end of the valve joint is communicated with one end of a tube base, the other end of which is connected with a spiral tube. A cylindrical body is connected with the valve joint, and the outer side of the cylindrical body is provided with a movable sleeve. Therefore, the utility model has the functions of current limiting and damping, and throttling and delaying a target (pulsation pressure) to be measured which has little cyclic variation to obtain a better use effect.
Description
Technical field: the utility model relates to a kind of matching parts of pressure measuring instruments category.Specifically, it belongs to and can be intended to a kind of adjustable throttle valve that matches with selected pressure instrumentation.
Background technique: at present, only have the function of damming, and do not have the effect of throttling delay with the stopcock of pressure instrumentation institute adapted; Adopt general bend pipe connection set, also be not enough to play the effect that throttling postpones.Therefore, in a single day have in measurand under the situation of certain pressure pulsation, be difficult to and the universal supporting application of pressure instrumentation.
Summary of the invention: even if the purpose of the utility model provide a kind of have periodically variable arbitrarily with the supporting operating mode that then can be applicable to measurand of pressure instrumentation non-ly acutely have under the fluctuation pressure, and the adjustable throttle valve firm in structure durable, easy and simple to handle, that maintenance is very little again.
For finishing the technological scheme that above-mentioned purpose is taked, the adjusting screw of valve body is set in the utility model valve joint, valve joint one end is communicated with base, base one end is welded in volute, it is simplified that establish in the volute outside, and simplified and valve joint are by being threaded cylindrical shell arranged outside sleeve.Above-mentioned adjustable throttle valve is to use for reference the action principle of common stopcock, adopted the structural type similar to adjustable isolation mounting, promptly in valve joint, be provided with adjusting screw, volute at its pressure guide hole one end connecting band base, to change the bad condition of measured variable fluctuation pressure, promptly by the current limliting amount of decrease be the pulsation amplitude of pressure and throttling postpone until the pilot chamber by produce corresponding in pressure so that selected pressure instrumentation can obtain is stable measured.
Avoid the pollution or the mechanical deterioration of external environment for the main body that makes valve, be provided with movable cover letter on the valve joint limit with the outer surface of cylindrical shell and protected.
The utility model can be arbitrarily and the supporting use of pressure instrumentation, and in the needs maintenance or when changing instrument, install and remove rather easy.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model.
Embodiment: the utility model structure accompanying drawing 1 is done following further describing.
This valve is made up of two-part: first portion is an adjusting mechanism, is made of valve joint 1, adjusting screw 2 and O-ring seals 3; Part 2 is the pilot chamber, is made of volute 5, base 4 and cylindrical shell 6.With above two-part combination back as a whole, outermost surface is established quill 7, thus, if with selected pressure instrumentation equipped after, promptly becoming one can be for measuring the pressure instrumentation with general fluctuation pressure.
