Abstract
The utility model belongs to the technical field of pressure regulation equipment for fuel gas, and discloses a fuel gas pressure regulator, which is mainly technologically characterized by comprising a valve body with an inlet, a valve port and an outlet; the valve body is provided with a regulation cavity and a cutting-off cavity; the regulation cavity is provided with a diaphragm; a valve rod connected with the diaphragm is provided with a spring and a valve clack connected with a valve drum; and the valve body is provided with a valve sleeve matched with the valve drum. When the fuel gas pressure regulator provided by the utility model is used, the spring is extended and retreated to drive the diaphragm and the valve rod to vertically move due to the fuel gas pressure change in a lower cavity of the diaphragm, and the clearance between the valve port and the valve clack is adjusted to adjust the pressure of a gas outlet end. When the valve rod drives the valve clack to vertically move, the valve drum linearly moves along the valve sleeve, so the valve rod and the valve clack do not have an offset, the pressure regulation precision is improved and the stability of outlet pressure is good.
Description
Technical field
The utility model belongs to combustion gas voltage adjusting device technical field, relates in particular to a kind of gas pressure regulator, governor.
Background technique
Gas pressure regulator, governor is to be specially adapted in the gas transmission and distribution system being widely used in the gas transmission and distribution engineering as the combustion gas voltage adjusting device of pressure regulation, voltage stabilizing.Its effect is to regulate gas outlet pressure automatically, makes it be stabilized in a certain pressure range, satisfies the force value of customer requirements, satisfies usage requirement.Pressure governor comprises the valve body that has import, valve port and outlet, and valve body is provided with to be regulated the chamber and cut off the chamber, regulates the chamber and is provided with diaphragm, and the valve rod that is connected with diaphragm has spring and flap.During use, diaphragm cavity of resorption gaseous-pressure changes makes telescopic spring drive diaphragm and valve rod moves up and down, and regulates valve port and flap gap with the adjusting end pressure of giving vent to anger.The valve rod of this gas pressure regulator, governor moves up and down and occurs deviation easily, influences outlet pressure stability.
The model utility content
Technical problem to be solved in the utility model just provides a kind of gas pressure regulator, governor of outlet pressure good stability.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the valve body that has import, valve port and outlet, valve body is provided with to be regulated the chamber and cuts off the chamber, regulate the chamber and be provided with diaphragm, the valve rod that is connected with diaphragm has spring and flap, described flap is connected with valve cylinder, and valve body is provided with the valve pocket that is complementary with valve cylinder.
A kind of gas pressure regulator, governor provided by the utility model, flap is connected with valve cylinder, and valve body is provided with the valve pocket that is complementary with valve cylinder.During use, diaphragm cavity of resorption gaseous-pressure changes makes telescopic spring drive diaphragm and valve rod moves up and down, and regulates valve port and flap gap with the adjusting end pressure of giving vent to anger.When valve rod drive flap moved up and down, valve cylinder made valve rod and flap deviation can not occur along the valve pocket straight line motion, thereby improves the pressure regulation precision, makes the outlet pressure good stability.
Description of drawings
Fig. 1 is the structural representation of a kind of gas pressure regulator, governor of the utility model.
Embodiment
Be described in further details below in conjunction with structure and the working principle of accompanying drawing to a kind of gas pressure regulator, governor of the utility model.
As shown in Figure 1, a kind of gas pressure regulator, governor of the utility model comprises valve body 1, valve body 1 has import 2, valve port 3 and exports 4, valve body 1 is provided with to be regulated chamber 5 and cuts off chamber 6, regulate chamber 5 and be provided with diaphragm 7, the valve rod 8 that is connected with diaphragm 7 has spring 9 and flap 10, and flap 10 is connected with valve cylinder 11, and valve body 1 is provided with the valve pocket 12 that is complementary with valve cylinder 11.
When a kind of gas pressure regulator, governor provided by the utility model used, diaphragm 7 cavity of resorption gaseous-pressures change moved up and down spring 9 telescopic band dynamic diaphragms 7 and valve rod 8, regulated valve port 3 and flap 10 gaps with the adjusting end pressure of giving vent to anger.When valve rod 8 drive flaps 10 moved up and down, valve cylinder 11 made valve rod 8 and flap 10 deviation can not occur along valve pocket 12 straight line motions, thereby improves the pressure regulation precision, makes the outlet pressure good stability.
A kind of gas pressure regulator, governor that the utility model provides is not limited only to said structure, so long as structure is identical with the utility model, all falls into the utility model protection domain.
