Abstract
The utility model discloses a gas pressure regulator signal pipe connection structure, its characterized in that: this connection structure includes the coupling that is used for with the signal pipe butt joint, the coupling has the interior interface of step and the outer tip of outside loudspeaker form, sets up seal assembly A and seal assembly B between the coupling of signal pipe and butt joint, signal pipe sets up fastening components with the outside of coupling butt joint, the sealing ring is located between signal pipe, coupling and the seal assembly B. The utility model discloses changed that signal pipe that the directness divides the problem of being connected with sensor portion in the present gas product, firm zonulae occludens between signal pipe and the coupling, even the long -time back of using, obscissions such as crack can not appear in its connection position, the circumstances of junction unstability more can not appear, have guaranteed the leakproofness of atmospheric pressure, can not influence the detection effect of sensor, are favorable to properties of product such as trip valve, voltage regulator and life's extension.
Description
Technical field
The utility model relates to a kind of gas pressure regulating field, especially a kind of gas pressure regulator, governor signal tube linkage structure.
Background technique
Along with the change of China's energy resource structure and continuing to increase of environmental protection dynamics, the development and utilization of rock gas is made to obtain swift and violent development.Compressed natural gas is that well head rock gas or the laggard horizontal high voltage of pipe natural gas purification compression are stored and transport, arrives place to use, directly inputs pipe network supply all types of user through multi-stage heat exchanger, pressure regulation.Gas generally could finally will be used by user through the pressure regulation of regulator, and Gas Pressure Regulating Equipment is generally made up of several function module, as pressure governor realizes voltage regulation function; Filter realizes clean filtering function etc.; In recent years, because wideling popularize of the clean energy resourcies such as rock gas, Gas Regulator also obtains applying more widely, and therefore relevant departments also strengthen the supervision of the design of the type device, manufacture, use, make quality of product further be ensured and improve.In existing voltage-regulating system, no matter be cut-off valve or pressure governor, its signal tube is all directly connect with corresponding Sensor section, and after using a period of time, its connection part easily occurs crack, easily comes off; Due to the instability of joint, easily cause pressurized seal poor, affect the effect that sensor detects, affect cut-off valve performance and working life; Be unfavorable for whole voltage-regulating system work simultaneously; Therefore need to be improved.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of gas pressure regulator, governor signal tube linkage structure is provided at this, changing signal tube in existing fuel gas product is the problem be directly connected with Sensor section, between signal tube with pipe joint, secure rigid is connected, after using even if long-time, its connection part there will not be the obscissions such as crack, more there will not be the situation of joint instability, ensure that the sealing of air pressure, the Detection results of sensor can not be affected, be conducive to the prolongation in the product performance such as cut-off valve, pressure governor and working life.
The utility model is achieved in that a kind of gas pressure regulator, governor signal tube linkage structure of structure, it is characterized in that: this linkage structure comprises the pipe joint for docking with signal tube; Pipe joint has outside trumpet-shaped step inner joint and outer end, arranges black box A and black box B between signal tube and the pipe joint docked; The outer installment fastener assembly that signal tube docks with pipe joint; Seal ring is between signal tube, pipe joint and black box B.
The utility model has the advantage of: the utility model provides a kind of gas pressure regulator, governor signal tube linkage structure by improving at this, changing signal tube in existing fuel gas product is the problem be directly connected with Sensor section, between signal tube with pipe joint, secure rigid is connected, after using even if long-time, its connection part there will not be the obscissions such as crack, more there will not be the situation of joint instability, ensure that the sealing of air pressure, the Detection results of sensor can not be affected, be conducive to cut-off valve, the prolongation in the product performance such as pressure governor and working life, also be conducive to the operation of whole gas pressure regulating system simultaneously.
