Background
A gas pressure regulator, commonly called a pressure reducing valve, is a device that automatically changes the flow of gas through a regulating valve to maintain a predetermined pressure of gas at an outlet. Generally, the method is classified into a direct action type and an indirect action type.
At present, a gas pressure regulator on the market comprises a valve body with an inlet and an outlet, a valve seat, a valve core and a pressure regulating device, and the valve core is regulated by the pressure regulating device to move relative to the valve seat, so that the size of an opening on the valve seat can be regulated, and the purpose of controlling flow is achieved. In the prior art, in the working process of the pressure regulator, the downstream air pressure can be gradually reduced along with the increase of the downstream air consumption, when the air pressure is reduced to a certain degree, the pressure stabilizing precision (the maximum pressure stabilizing precision specified by the national standard is AC 15) of the normal working of the pressure regulator is exceeded, the flow which can be reached by the pressure regulator is the maximum flow of the pressure regulator (namely, the opening of the valve seat is completely opened), and the air pressure entering the downstream is not uniform and the air flow is unstable due to the overlarge flow passing through the valve seat at the moment, so that the pressure stabilizing precision is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a simple structure, simple to operate can improve the steady voltage precision of the pressure regulator and can increase the flow of the pressure regulator so as to improve the gas pressure regulator's of pressure regulator application range flow stabilizer.
In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a flow stabilizer of gas pressure regulator, includes the valve body, adorns the disk seat in the valve body admittedly and is used for opening the disk seat or close the case of disk seat, the valve body includes air inlet and gas outlet, form the chamber of admitting air between disk seat and air inlet in the valve body, form the chamber of giving vent to anger between disk seat and the gas outlet in the valve body, a stationary flow circle has been cup jointed to the disk seat towards the one end of giving vent to anger the chamber, the stationary flow circles and is provided with the through-hole that supplies the fluid circulation, the lateral wall circumference equipartition of stationary flow circle have at least two with.
Adopt above-mentioned scheme, cup joint a stationary flow circle on the disk seat, make the gas can pass through the stationary flow circle the through-hole that sets up and enter into the intracavity of giving vent to anger, and because the lateral wall circumference equipartition at stationary flow circle has the water conservancy diversion hole with the through-hole intercommunication, consequently the gas also can enter into the intracavity of giving vent to anger through the water conservancy diversion hole, the common water conservancy diversion through-hole and water conservancy diversion hole can improve the flow size, when the case is in under the complete open mode, compare prior art, its maximum flow has obvious improvement, consequently, can improve the application range of voltage. And because the even reposition of redundant personnel of each water conservancy diversion hole can make the atmospheric pressure that the air current that gets into the air outlet cavity formed tend to stability again, can not cause the inhomogeneous condition of atmospheric pressure, improved steady voltage precision. The device has the advantages of simple structure, quick installation, convenient maintenance and the like.
As the utility model discloses a further setting, the disk seat is adorned admits air the one end in chamber admits air admittedly on the valve body, the lateral wall that the disk seat orientation goes out air cavity one end is provided with positioning groove, the inside wall of stationary flow circle be provided with be used for with positioning groove forms joint complex location lug.
By adopting the scheme, the positioning groove is formed in the valve seat, and the positioning lug is arranged on the inner side wall of the flow stabilizing ring, so that when the flow stabilizing ring is sleeved on the valve seat, the positioning lug can be embedded into the positioning groove to form clamping fit, the condition that the flow stabilizing ring slides axially to fall off can be prevented, and the product stability is improved.
As a further setting of the utility model, the lateral wall that the disk seat orientation goes out air cavity one end is provided with the straight line annular knurl, stationary flow circle inside wall be provided with at least one with the bump that the cooperation of straight line annular knurl was prevented changeing.
By adopting the scheme, the straight-line knurls are processed on the side wall of the valve seat, and the salient points are arranged on the inner side wall of the flow stabilizing ring, so that large friction is formed between the salient points and the straight-line knurls, the flow stabilizing ring can be prevented from rotating circumferentially relative to the valve seat, and the purpose of preventing rotation is achieved.
As a further setting of the utility model, the one end of disk seat orientation air inlet chamber with the valve body spiro union is fixed.
By adopting the scheme, the valve seat is fixed with the valve body in a threaded manner, so that the valve is more convenient to install.
As a further arrangement of the utility model, the steady flow ring is made of spring steel.
By adopting the scheme, the steady flow ring is made of special spring steel and can have holding force with certain strength.
The present invention will be further described with reference to the accompanying drawings.
