Abstract
The utility model discloses a pressure regulating and controlling pressure reducing valve end plate, which comprises a cap-shaped end plate (1), wherein a pressure compensation opening (3) is formed right above the cap-shaped end plate (1), and an installing hole (2) is formed in the cap-shaped end plate (1). The pressure regulating and controlling pressure reducing valve end plate has the advantages and beneficial effects that the pressure compensation opening is formed in the cap-shaped end plate, and the long-time stable work of a pressure reducing valve can be ensured.
Description
Technical field
The utility model relates to air valve technical field, particularly a kind of regulate and control the reduction valve end plate of pressure.
Background technique
Reduction valve is a kind of special arrangement of automatic reduction working pressure of pipeline, and it can be reduced to fluid pressure higher pipeline before valve the required level of pipeline after valve.The structural type of reduction valve is a lot, can be divided into diaphragm type, spring diaphragm type, piston type, Lever type and bellow type etc. by structural type.Press artificially single seated and double seat of valve seat number.Can be divided into positive interaction type and reaction-type by the position difference of flap.Can be divided into nitrogen reduction valve, hydrogen reduction valve, oxygen pressure reducing valve etc. by medium.The basic role principle of reduction valve is, by valve inner flow passage, the local resistance of current is reduced to hydraulic pressure, and the scope that hydraulic pressure falls is by connecting the film of flap or the import and export differential water pressures of piston both sides regulates automatically.
The reduction valve tip plate configurations function singleness of traditional regulation and control pressure, does not have pressure compensation mouth.
Model utility content
For solving the reduction valve tip plate configurations function singleness of traditional regulation and control pressure, there is no the problem of pressure compensation mouth, the utility model provide a kind of regulate and control the reduction valve end plate of pressure.
The purpose of this utility model is achieved through the following technical solutions:
The reduction valve end plate of regulation and control pressure, comprises cap shape end plate, directly over cap shape end plate, is provided with pressure compensation mouth, and mounting hole is arranged on cap shape end plate.
As further improvement, also comprise water outlet, water outlet is arranged on described cap shape end plate, and the effect of water outlet is the water outlet of reduction valve circulating water while heating.
As further improvement, have at least three described mounting holes to be arranged on cap shape end plate, cap shape end plate can be fixedly secured on relief valve body.
As further improvement, described mounting hole is evenly distributed on taking cap shape end plate central point on the circumference in the center of circle, makes to install more firm.
As further improvement, the material of described cap shape end plate is that Kohlenstoffgehalt is the carbon steel carbon of 0.3-0.5 %, and content is the rigidity requirement that the carbon steel of 0.3-0.5 % can meet chamber.
As further improvement, it is characterized in that, the diameter of described pressure compensation mouth is 10-20mm, can meet user demand.
In sum, advantage of the present utility model and beneficial effect are:
The reduction valve tip plate configurations function singleness of traditional regulation and control pressure, does not have pressure compensation mouth.The utility model is provided with pressure compensation mouth on cap shape end plate, can ensure reduction valve long-term stable operation.
