Description

Water heater check valve anchor clamps

Technical Field

The utility model belongs to the technical field of anchor clamps, concretely relates to water heater check valve anchor clamps.

Background

The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. Check valves are also known as check valves or check valves. For preventing reverse flow of oil in hydraulic systems or for preventing reverse flow of compressed air in pneumatic systems.

The utility model provides a check valve for water heater, its structure includes water inlet, delivery port, escape orifice and control mouth, and the pipeline middle part of water inlet and delivery port still is equipped with the instruction arrow point of instruction rivers direction, and the delivery port outside is equipped with outer hexagon nut for the installation of check valve. Such check valves typically have a check function and a pressure relief function in water heater applications. The non-return function is that the non-return function is arranged at the water inlet at the bottom of the one-way valve, so that the one-way valve only can feed water but can not discharge water, and the burnt hot water can be prevented from flowing back to a pipeline; and pressure relief function installs pressure relief device in for the valve body, and when pressure exceeded the rated pressure of check valve when running water pipeline pressure or through electric heating, the check valve can be automatically through the mode that the drain hole drips and come the too high pressure of draining, when the drainage is forced to needs, can control the drainage through the control assembly of control mouth installation. Therefore, the machining of the respective ports of the check valve must be relatively precise to enable good installation of the respective components that satisfy the various functions.

FIG. 1 is a schematic structural view of a fixture for a check valve of a water heater according to the present invention;

in the drawings: 10-a first cylindrical section, 11-a second cylindrical section, 12-a first fixing part, 13-a second fixing part, 14-a positioning groove, 15-a third fixing part, 16-an expansion joint and 17-a fourth fixing part.

Detailed Description

The features and characteristics of the present invention will be described in further detail below with reference to the attached drawings.

As shown in fig. 1, a water heater check valve anchor clamps, including first cylinder section 10 and second cylinder section 11, the inside of first cylinder section 10 and second cylinder section 11 is equipped with the through-hole, the through-hole is as fourth fixed part 17, the one end that fourth fixed part 17 is located second cylinder section 11 is equipped with the hexagon socket head cap, the hexagon socket head cap is as third fixed part 15, and this end still is equipped with constant head tank 14, be provided with logical groove on the second cylinder section 11, logical groove is as second fixed part 13, the rectangular channel has still been seted up at the rear portion of second fixed part 13, the rectangular channel is as first fixed part 12, be equipped with expansion joint 16 along the axial on the second cylinder section 11. The fourth fixing portion 17 is used for fixing a pipeline from a water inlet to a water outlet of the water heater check valve, the third fixing portion 15 is used for fixing an outer hexagon nut at the water outlet, the second fixing portion 13 is used for fixing a pipeline at a control port of the water heater check valve, and the first fixing portion 12 is used for fixing a pipeline of a drain hole. The positioning groove 14 is used for positioning and fixing an indication arrow on the water heater check valve, and the expansion joint 16 is used for slightly contracting the expansion joint 16 when a machine for external processing applies a certain force when the clamp clamps the water heater check valve, so that the clamp can more stably clamp the water heater check valve.

When the fixture is in practical use, one end of a water inlet of the water heater check valve is placed into the through hole of the first cylindrical section 10 through the through hole of the second cylindrical section 11 of the fixture, at the moment, a pipeline from the water inlet to the water outlet is completely included in the through hole, namely, the pipeline is fixed by the fourth fixing part 17, the pipeline of the control port is fixed by the second fixing part 13, the pipeline of the drain hole is fixed by the first fixing part 12, the third fixing part 15 is matched with the outer hexagon nut of the water outlet, and the indication arrow is positioned in the positioning groove 14. When the clamp and the water heater check valve are assembled, the clamp can be machined, and when the clamp is clamped by a machine, the expansion joint 16 is slightly contracted to fix the water heater check valve more stably in one step. And the indication arrow is positioned in the positioning groove 14, and the water heater check valve is fixed, so that the cooperation of the indication arrow and the positioning groove 14 can prevent the water heater check valve from axially sliding out from the through hole of the clamp.

Besides, the length and the width of the positioning groove 14 of the clamp are the same as those of the indication arrow of the one-way valve of the water heater, and the indication arrow can be guaranteed to have a better fixing effect in the positioning groove 14 due to the fact that the length and the width are the same. In order to ensure the expansion effect of the expansion joint 16, the one-way valve of the water heater clamped by the fixture is more stable, so that the expansion joint 16 penetrates from the outer cylindrical surface to the inner cylindrical surface of the second cylindrical section 11. Under the prerequisite that reaches good flexible effect, the quantity of expansion joint 16 can set up to the strip, and every two adjacent expansion joints 16 mutually perpendicular, and one of them expansion joint 16 can be located the middle part of first fixed part 12 and second fixed part 13, because expansion joint 16's flexible effect like this in the course of working, the pipeline of this anchor clamps to the last discharge orifice of water heater check valve and the pipeline centre gripping of control port can be more firm. In order to save material and to facilitate the gripping of the clamp, the diameter of the first cylindrical section 10 may be made smaller than the diameter of the second cylindrical section 11.
