Description

A New Vacuum Tube Orifice Sealing Plug

technical field

The utility model relates to a novel vacuum tube nozzle sealing plug, in particular to a novel vacuum tube nozzle sealing plug in which a sealing ring main body and a sealing ring are combined together.

Background technique

With the maturity of solar thermal utilization technology, the market demand for solar products is also increasing, the pressure of market competition is high and the requirements of customers for product quality are getting higher and higher. As the key position to ensure the quality of product processing, More and more companies have paid more and more attention to it, and the inspection and efficiency requirements for the inner tank have also become higher and higher.

The current inspection is to install a water test plug after installing a silicone ring at the vacuum nozzle, then use tooling to fasten it, and then use air pressure to test in the water test pool, which is very cumbersome to install. When the vacuum nozzle is sealed with two stations, it is more troublesome to install the silicone ring and the main body of the sealing plug. After the inspection is completed, the main body of the sealing plug should be removed first, and then the silicone sealing plug, which is also a waste of time. Since the number of nozzles of the product is not fixed, the more the number, the longer the inspection time will be, which will lead to the different processing efficiency of the product. In order to improve the efficiency, it is necessary to improve the sealing method of the nozzle.

Contents of the invention

In order to overcome the disadvantages of the above-mentioned technical problems, the utility model provides a novel vacuum tube mouth sealing plug in which the main body of the sealing ring and the sealing ring are combined together.

The novel sealing plug of the nozzle of the vacuum tube of the utility model includes a sealing plug main body which plays a supporting role. The lower groove; the sealing ring is in the shape of a cylinder with two ends open, and the inner surface of the sealing ring is provided with several annular protrusions matching the lower groove. The main body of the sealing plug plays a supporting role, and the outer surface of the lower part of the main body of the sealing plug is provided with a number of annular lower grooves, so that the sealing ring can realize the connection between the sealing ring and the main body of the sealing plug through the annular protrusion arranged on the inner cavity. Connect firmly. Then cooperate with the vacuum tube through the sealing ring to realize the sealing effect on the vacuum tube.

In the novel sealing plug of the nozzle of the vacuum tube of the utility model, the upper part of the main body of the sealing plug is provided with an upper groove which is convenient to be held by hand. During the use of the sealing plug of the utility model, due to the need for installation and disassembly, after the upper groove is provided, the staff can hold the sealing plug very conveniently.

In the novel sealing plug of the nozzle of the vacuum tube of the utility model, the main body of the sealing plug is made of nylon material; the material of the sealing ring is silica gel. The main body of the sealing plug is made of nylon material, which can ensure that the main body of the sealing plug has a long service life; the sealing ring is made of silica gel material, which can ensure good sealing performance between the sealing plug of the present invention and the vacuum nozzle of the water heater.

The beneficial effects of the utility model are: the utility model effectively realizes the sealing effect on the vacuum tube of the water heater by setting the main body of the sealing plug and the sealing ring matched with the main body of the sealing plug, avoids the cumbersome step-by-step operation in the past, and improves the work efficiency. Efficiency: The main body of the sealing plug of the utility model is provided with an upper end groove matched with human hands, which further facilitates people's use.

Fig. 2 is a schematic structural view of the main body of the sealing plug of the present invention;

Fig. 3 is the structural representation of sealing ring of the present utility model;

In the figure: 1 main body of sealing plug, 2 sealing ring, 3 upper groove, 4 lower groove, 5 annular protrusion.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, a structural schematic diagram of the utility model is provided, which includes a sealing plug main body 1 and a sealing ring 2, and Fig. 2 and Fig. 3 respectively provide structural representations of the sealing plug main body and the sealing ring, and the shown sealing The upper end of the plug body 1 is provided with an upper end groove 3; the upper end groove 3 is used to cooperate with human hands during use, so that workers can hold it, which saves labor and improves work efficiency. The lower part of the sealing plug main body 1 is provided with several lower grooves 4 , and the lower grooves 4 are distributed in a ring shape along the outer surface of the sealing plug main body 1 . The sealing ring 2 shown is in the shape of a cylinder, on the inner surface of the sealing ring 2, there are several annular protrusions 5 matching the lower groove 4, the main body of the sealing plug 1 and the sealing ring 2 pass through the lower groove 4 and the ring The matching of the protrusions 5 can be tightly combined. In order to ensure that the vacuum tube nozzle sealing plug of the utility model has a relatively high service life, the sealing plug main body 1 is made of nylon material, and in order to ensure a good sealing effect on the vacuum tube of the water heater, the sealing ring 2 is made of silica gel material.

In the process of using the utility model, the main body 1 of the sealing plug provided with the sealing ring 2 can be directly inserted into the nozzle of the vacuum tube, which saves the cumbersome setting of the original sealing ring 2 and the main body 1 of the sealing plug, and saves time. Improve work efficiency.
