Abstract

The utility model discloses an exhaust type fast connector, which solves the existing problems that there is no special connector for pipeline connection and liquid delivery. It specifically includes an exhaust joint and a butt joint; the exhaust joint is connected to the butt joint; the exhaust joint and the butt joint are used to connect the empty sewage recovery pipeline or the dosing pipeline; An air release valve is also connected to the exhaust joint. It can realize the continuous delivery of liquid in the pipeline under pressure, save the time of pipeline connection and delivery, improve work efficiency, and ensure that there is no residual liquid in the pipeline after delivery, so as to prevent the liquid medicine or sewage from flowing to the ground to pollute the environment or the liquid medicine Loss is wasted.

Description

Exhaust quick connector

technical field

The utility model relates to a pipeline connector.

Background technique

At present, in the oil field, when the oil well tank truck is adding chemicals, the oil well casing gate is opened, and the rubber hose is directly inserted into the casing. When the air is pumped out, part of the liquid medicine flows to the ground to pollute the environment, which is time-consuming and wastes the liquid medicine.

At the same time, there are similar problems in the emptying of sewage recovery pipelines after cleaning of various tanks such as transfer stations, joint stations, and water injection stations in oil fields, and sewage recovery pipelines for water injection well cleaning.

Contents of the invention

In view of this, the utility model provides an exhaust type quick connector, which is widely used in various tanks such as transfer stations, joint stations, water injection stations, etc. after cleaning, emptying sewage recovery pipelines, oil well dosing tank cars and wellhead pipelines The quick connection and the liquid delivery of the pressurized pipeline can improve work efficiency and avoid polluting the environment.

For realizing above-mentioned purpose of the invention, the technical scheme that the utility model adopts is:

A vented quick connector, comprising:

Exhaust fittings and butt fittings;

The exhaust joint is connected to the butt joint;

The exhaust joint and the butt joint are used to connect the empty sewage recovery pipeline or the dosing pipeline;

An air release valve is also connected to the exhaust joint.

Preferably, the butt joint is a clamp type quick joint.

Preferably, the exhaust joint has a docking handle.

Beneficial effects of the utility model: the exhaust type quick connector is applied to the quick connection of the pressure pipeline, and discharges the gas in the pressure pipeline at any time, realizes the continuous delivery of the liquid in the pressure pipeline, saves connection and Delivery time, improve work efficiency, and ensure that there is no residual liquid in the pipeline after delivery, so as to avoid the liquid medicine or sewage flowing to the ground to pollute the environment or the loss and waste of the medicine solution.

Description of drawings

Through the following description of the embodiments of the utility model with reference to the accompanying drawings, the above-mentioned and other purposes, features and advantages of the utility model are more clear, in the accompanying drawings:

Fig. 1 is a schematic structural view of an exhaust type quick connector according to an embodiment of the present invention.

Detailed ways

The following describes the present invention based on examples, but it should be noted that the present invention is not limited to these examples. In the following detailed description of the present utility model, some specific details are described in detail. However, those skilled in the art can also fully understand the utility model for the parts that are not described in detail.

In addition, those of ordinary skill in the art should understand that the provided drawings are only for illustrating the purpose, features and advantages of the present utility model, and the drawings are not actually drawn to scale.

At the same time, unless the context clearly requires, the words "include", "include" and other similar words in the entire specification and claims should be interpreted as an inclusive meaning rather than an exclusive or exhaustive meaning; that is, "include but not limited to the meaning of ".

Fig. 1 is a schematic structural view of an exhaust type quick connector according to an embodiment of the present invention. As shown in Figure 1: an exhaust type quick connector, including:

Exhaust joint 1 and butt joint 3;

The exhaust joint 1 is connected with the butt joint 3;

The exhaust joint 1 and the butt joint 3 are connected to the empty sewage recovery pipeline or the dosing pipeline;

An air release valve 2 is also connected to the exhaust joint 1 .

Further, in FIG. 1 , the butt joint 3 is a clamp type quick joint.

Further, in FIG. 1 , the exhaust joint 1 has a docking handle 4 .

Specifically, in conjunction with Fig. 1, a brief description is given of the process of the utility model being applied to oil well tank trucks for dosing:

The left end of the exhaust joint 1 is connected with the oil well casing thread, the right end of the exhaust joint 1 is fixedly connected with the clamp type quick joint 3, and the other end of the clamp type quick joint 3 is connected with the tank car dosing hose, and the tank car and the oil well casing pipeline connected. Open the dosing valve of the tank truck, and the liquid medicine flows into the casing. If the casing pressure is high, open the air release valve 2 to exhaust while adding the liquid medicine; Remove the quick connector hose end first, then remove the connector and close the casing gate.

The above-mentioned embodiment is only to express the embodiment of the utility model, and its description is relatively specific and detailed, but it should not be understood as limiting the patent scope of the utility model. It should be pointed out that those skilled in the art can make several modifications, equivalent replacements, improvements, etc. without departing from the concept of the utility model, all of which belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
