Abstract
The utility model provides an adjustable pressure stabilizer for a pressure meter, which is composed of a casing provided with two inner cavities of which the middles are communicated, wherein, one inner cavity is an inlet and the other inner cavity is an outlet. The utility model is characterized in that a pressure stabilizing mechanism which is formed by that a small spring, a plunger and an adjusting screw are placed in order from inside to outside is arranged in the inner cavity which is served as the inlet. The adjustable pressure stabilizer for a pressure meter provided by the utility model has the advantages that the swinging phenomenon of a pointer of the pressure meter is eliminated; the pointer of the pressure meter stably displays the indicated value of the operating pressure of the point, and therefore, a stoker can clearly readout the operating pressure of the pressure meter, and therefore, the accuracy of the pressure display value is not affected due to the problem that the error is created by the swinging phenomenon; simultaneously the problem that the pressure meter bears the impact in moment due to an electric centrifugal pump is suddenly started up, and then the pointer is rotated at very high speed to damage the pressure meter is solved.
Description
Technical field:
The utility model relates to stable-pressure device, and a kind of adjustable pressure table voltage stabilizer that is used for pipeline circulating system particularly is provided.
Background technique:
According to " steam boiler safety and technical supervision rules " and " water-heating boiler safety and technical supervision rules " correlation technique: should install pressure gauge on boiler feedwater pump, the circulating pump discharge pipe hereinafter to be referred as " rules ", and influence such as should prevent to be given a shock, beat and should stop using when pointer appears in pressure gauge.But in existing boiler feed water equipment, usually adopt the make-up pump and the circulating water pump of electric centrifugal pump as boiler, electric centrifugal pump is that the centrifugal power that utilizes electric drive " blade " high speed rotating to produce reaches the feedwater purpose, and this centrifugal power has certain pulse feature, therefore, at the boiler feedwater pump, the gauge hand of installing on the circulating pump discharge pipe, fierce swing just constantly takes place along with the variation of pulse power, and amplitude of fluctuation is bigger, generally about 30 °, the stoker personnel can't accurately read pump outlet pressure gauge working pressure indicating value to its beat of pointer angle.That is to say that under actual conditions, this pressure gauge is not brought into play its useful effect, perform practically no function, and caused waste.
Summary of the invention:
The purpose of this utility model is to provide a kind of adjustable pressure table voltage stabilizer, and it can make manometric indication accurately also stable, and it is simple in structure, easy to maintenance.
The utility model provides a kind of adjustable pressure table voltage stabilizer, housing (1) by the inner chamber that has two intermediate connections constitutes, an inner chamber is inlet (2), another inner chamber is characterized in that for exporting (3): be provided with little spring (4), the piston of placing successively from the inside to the outside (5), the pressure stability mechanism that adjusts screw (6) formation in the described inner chamber as inlet (2).
In the utility model adjustable pressure table voltage stabilizer, piston (5) is preferably the piston that has guide mechanism (6).
To seal more easily in order realizing operating, in the utility model adjustable pressure table voltage stabilizer, can also to be provided with the spring of placing successively from the inside to the outside (7), the sealing mechanism that seal rubber pad (8) constitutes in the inner chamber as outlet (3).
For easy for installation, in the utility model adjustable pressure table voltage stabilizer, the outside of housing (1) is provided with the paired working surface that is parallel to each other.
In the utility model adjustable pressure table voltage stabilizer, the inlet (2) of housing (1) is an external thread structure, and outlet (2) is a female thread structure.
The utility model can be installed between pressure gauge and the trap pipe, and directly is connected with pressure gauge.By in the boiler room site test, the result shows:
1, thoroughly eliminated the dancing of pump discharge place gauge hand, its pointer stably demonstrates this and puts working pressure value of living in, and the stoker personnel can clearly read its working pressure indicating value, thereby has solved practical challenges effectively.
2, the pressure gauge indicating value does not have to take place to cause the problem of " error " thus, and influences its accuracy.
3, solved unexpectedly simultaneously because electric centrifugal pump starts suddenly, pressure gauge was impacted in moment, made the very fast rotation of its pointer and the pressure gauge that causes damages problem.Can see in the practical operation that manometric pointer gently rises to working pressure value position, thereby protect pressure gauge effectively, satisfy the related request of " " rules " " preferably.
In a word, the utility model can start the size of the pulse power that the back produced according to electric centrifugal pump, adjusts, can be accurately to reach pump discharge place gauge hand, stablize and show its working pressure value unchangeably.The utility model device does not have pressure error and produces, and do not influence its accuracy, and volume is little, rational in infrastructure, easy to maintenance.
Description of drawings:
Fig. 1 is the signal of adjustable pressure table stabilizator structure.
Embodiment:
Embodiment 1
As shown in Figure 1, adjustable pressure table voltage stabilizer housing (1), the sealing mechanism that a built-in spring of cavity (7), seal rubber pad (8) equal pressure table obturator constitute; The pressure stability mechanism that the built-in little spring of another cavity (4), piston (5), adjustment screw (6) constitute; Housing (1) sealing mechanism one end is a female thread structure, and this end is connected with pressure gauge; Housing (1) pressure stability mechanism one end is an external thread structure, and this end is connected with the boiler pipe system.Directed mobile piston (5) in the pressure stability mechanism passes little spring (4), thereunder rely on housing pin (6) to adjust the degree that little spring (4) compresses, in order to the elimination pulsed power that electric centrifugal pump produced, and have adjustability, play " damping ".The sealing mechanism that spring (7), seal rubber pad (8) equal pressure table obturator constitute has constituted manometric " just connecing " device, in other words, when the setting pressure table, need not be tied with the linen thread of paint on the manometric screw thread, can directly install, as long as the pressure gauge sealing surface contacts with seal rubber pad, it realizes sealing by intrasystem pressure, interior pressure is big more, and sealing effect is good more.The bottom of housing (1) is that hexagon has 3 pairs of parallel working surfaces, is convenient to install with instrument.
