Description

A drain valve seat

Technical field:

The invention relates to the technical field of water discharge valves, in particular to a water discharge valve seat.

Background technique:

The drain valve is one of the most important components on the car radiator or condenser. In an all-aluminum radiator, the water discharge valve is generally in an inverted T shape, and a concave platform is formed on the top to match the sealing ring on the water discharge valve. The drain valve seat is generally fixed on the water chamber of the radiator by welding, but because the wall thickness of the water chamber of the all-aluminum radiator is relatively thin, the welding requirements are increased, and the welding skills of the welders vary from person to person, which not only produces The efficiency is not high, and the quality stability of the product is poor, and the welding cost is high;

Although the water discharge valve seat connected by bolts has avoided the influence caused by welding, the sealing ring on the water discharge valve seat will be affected by the temperature generated when the water chamber and the radiator core are welded, so it can only be used in the basic After the welding is completed, the water discharge valve seat is installed, and the installation of the water discharge valve seat can only be done by entering the water inlet and outlet pipes on the water chamber, and because the reserved hole for installing the water discharge valve seat is no longer near the water inlet and outlet pipes, it is troublesome to install.

Invention content:

The object of the present invention is to provide a drain valve seat for the deficiencies of the prior art, which is fixed on the radiator through bolt connection, and the installation is convenient and quick.

Technical solutions of the present invention are as follows:

A water discharge valve seat, including a body of the water discharge valve seat, the body is composed of a chassis, a round platform and a cylinder, a round platform is formed on the upper end surface of the chassis, a cylinder is formed on the upper end surface of the round platform, and a concave platform is formed on the top surface of the cylinder. The bottom surface of the concave platform is formed with a threaded hole that runs through the bottom surface of the chassis; the circular platform is inserted with a sealing ring, and the inner wall of the sealing ring is pressed against the outer wall of the circular platform; the outer wall of the upper end of the cylinder is formed with a The opposite grooving, the outer wall of the cylinder on the lower side of the grooving is threaded, and the thread of the cylinder is screwed with an inverted concave-shaped screw sleeve. The upper end of the sealing ring is inserted into the screw sleeve and pressed against the screw sleeve. put on.

The inner wall of the sealing ring is conical, and the conical angle of the inner wall of the sealing ring is the same as that of the truncated cone.

The diameter of the upper end surface of the circular platform is greater than the diameter of the cylinder.

There are several symmetrical cutting edges on the outer wall of the screw sleeve.

The beneficial effects of the present invention are:

It has a simple structure and can be connected to the radiator instead of welding, so that welding is not required, and welding costs are saved. At the same time, it is not necessary to install the water discharge valve seat through the water inlet and outlet pipes on the radiator after welding, which facilitates the installation process of the water discharge valve seat.

Detailed ways:

Embodiment: As shown in Figures 1 to 3, a water discharge valve seat includes a body 1 of the water discharge valve seat. The body 1 is composed of a chassis 11, a round platform 12 and a cylinder 13. The upper end surface of the chassis 11 is formed with a round platform 12, a round platform A cylinder 13 is formed on the upper end surface of the cylinder 12, a concave platform 17 is formed on the top surface of the cylinder 13, and a threaded hole 16 penetrating the bottom surface of the chassis 11 is formed on the bottom surface of the concave platform 17; ring 2, the inner wall of the sealing ring 2 is pressed against the outer wall of the round platform 12; the outer wall of the upper end of the cylinder 13 is formed with a corresponding cutout 14, and the outer sidewall of the cylinder 13 on the lower side of the cutout 14 is formed with a screw thread 15. The screw thread 15 of the cylinder 13 is screwed with an inverted concave-shaped screw sleeve 3 , and the upper end of the sealing ring 2 is inserted into the screw sleeve 3 and pressed against the screw sleeve 3 .

The inner wall of the sealing ring 2 is conical, and the conical angle of the inner wall of the sealing ring 2 is the same as that of the frustum 12 .

The diameter of the upper end surface of the circular platform 12 is larger than the diameter of the cylinder 13 .

There are several symmetrical cutting edges 31 on the outer wall of the screw sleeve 3 .

Working principle: The water discharge valve seat of the present invention replaces the welding method by threaded connection, which avoids the disadvantages caused by the welding method; at the same time, the water discharge valve seat does not need to be installed after the basic welding of the all-aluminum radiator; it can be removed first For the sealing ring on the water discharge valve seat, when the water chamber and the core body are not welded, the body 1 and the screw sleeve 3 are first fixed in the water chamber, and then the water chamber and the core body are welded, so that the sealing ring 2 will not be affected by the water chamber. The influence of temperature when welding with the core body, after the water chamber and the core body are welded and cooled, then remove the screw sleeve 3 on the water discharge valve seat, insert the sealing ring 2 on the sleeve, lock the screw sleeve 3, the screw sleeve 3 The sealing ring 2 is urged to move and expand under pressure on the round table 12 of the body 1, thereby sealing the water discharge valve seat body 1 and its installation reserved hole.
