Abstract
The utility model discloses a liquid phthalic anhydride truck loading quick connector which comprises a quick connector body with the connector female end and the connector male end. The value of the size of the diameter of the inner wall of a female end connector at the connector female end is larger than the value of the size of the diameter of the inner wall of a male end connector at the connector male end, the value of the size of the diameter of the inner wall of the female end connector at the connector female end is larger than or equal to the value of the size of the diameter of the inner wall of a gasket of a sealing gasket which is mounted between the connector female end and the connector male end. The fluid guide effect on liquid media during truck loading is effectively improved, the effect of removing the impacting force borne by the sealing gasket of the female end face and the male end face of the quick connector is achieved, so that the reliability of the sealing gasket is guaranteed, and the service life of the sealing gasket is greatly prolonged. The problem of the potential safety hazard of leakage and spraying of the truck loading quick connector is solved.
Description
Technical field
The utility model relates to a kind of rapid pipe joint, especially relates to a kind of rapid pipe joint for the entrucking of liquid phthalic anhydride.
Background technique
Conventionally for the entrucking of these type high temp chemical product of liquid phthalic anhydride, the rapid pipe joint adopting, because the MEDIA FLOW of liquid body phthalic anhydride is to requiring effects limit, need flow from top to bottom, having limited thus the cloudy end of joint and sealing gasket should not be at upside, otherwise Joint's falling off or the distortion phenomenon that is shifted easily occurs; Yet due to conventionally for the entrucking of liquid acid anhydride, be subject to temperature substantially to surpass 140 ℃, working pressure reaches 0.5MPa, and back pressure is 0, the characteristic factor impacts such as 131.6 ℃, solidifying point, make the sealing gasket being arranged between the cloudy end of rapid pipe joint and oedoeagus affected by the impulse force of MEDIA FLOW, once there is leakage phenomenon, can cause work safety accident.
Model utility content
The utility model exists easy leakage for solving the sealing gasket of the rapid pipe joint of existing liquid phthalic anhydride entrucking, cause the present situations such as work safety accident and provide a kind ofly can effectively prevent that sealing gasket from leaking, prevent to produce the liquid phthalic anhydride entrucking rapid pipe joint of security incident.
The utility model is to solve the problems of the technologies described above adopted concrete technological scheme to be: a kind of liquid phthalic anhydride entrucking rapid pipe joint, comprise the rapid pipe joint with the cloudy end of joint and joint oedoeagus, it is characterized in that: the cloudy end of joint the diameter dimension value of cloudy end connector inner diameter be greater than the male coupling inner diameter size value of joint oedoeagus, the cloudy end of joint the diameter dimension value of cloudy end connector inner diameter be more than or equal to the packing ring inner diameter size value that is arranged on the sealing gasket between the cloudy end of joint and joint oedoeagus.Water conservancy diversion effect to liquid medium while effectively having improved entrucking, reaches elimination rapid pipe joint negative and positive end face seal pad and is subject to the impulse force effect of MEDIA FLOW, thereby guaranteed the reliability of sealing pad and greatly extended working life; Finally reach and eliminate the security hidden trouble that splash is leaked in entrucking rapid pipe joint.
As preferably, described joint oedoeagus and the seal face of sealing gasket are vertical seal termination face, between the packing ring inwall of vertical seal termination face and sealing gasket, form one end perpendicular steps, the male coupling inner diameter size value of its middle joint oedoeagus is less than the packing ring inner diameter size value of sealing gasket.Reduce to a greater extent and reduce the percussion of phthalic anhydride liquid to sealing gasket, improve the working life of sealing gasket.
As preferably, described male coupling inwall has the inner wall section of two ends different-diameter size value, what wherein near joint the moon, hold is the first male coupling inner wall section, what by liquid phthalic anhydride, pour direction outer end is the second male coupling inner wall section, and wherein the diameter dimension value of the second male coupling inner wall section diameter is less than the diameter dimension value of the first male coupling inner wall section diameter.Reduce to a greater extent and reduce phthalic anhydride liquid in the shunting action of male coupling inwall, reach the reduction to a greater extent percussion to sealing gasket, the working life of improving sealing gasket.
As preferably, the entrucking of described joint oedoeagus is installed external end head and is provided with several mounting holes.Raising is firm by the safe handling of rapid pipe joint, reliability.
The beneficial effects of the utility model are: the water conservancy diversion effect to liquid medium while effectively having improved entrucking, reach elimination rapid pipe joint negative and positive end face seal pad and be subject to the impulse force effect of MEDIA FLOW, thereby guaranteed the reliability of sealing pad and greatly extended working life; Finally reach and eliminate the security hidden trouble that splash is leaked in entrucking rapid pipe joint.
