Description
Technical Field
The utility model belongs to the technical field of anchor clamps, concretely relates to 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 corresponding pipeline, 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.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: the one-way valve clamp is provided, and aims to well fix a one-way valve when each port of the one-way valve is machined, so that the machining of each port is more accurate.
In order to solve the technical problem, the technical scheme of the utility model as follows:
a check valve clamp comprises a first clamping block and a second clamping block;
the first clamping block is a semicircular ring body, the inner diameter of the first clamping block is equal to the outer diameter of a control port pipeline, a semicircular first groove is formed in one side of the lower portion of the first clamping block, the radius of the first groove is the same as the outer diameter of a drain hole pipeline, a semicircular second groove which is parallel to the first groove is formed in the upper portion of the first clamping block, the radius of the second groove is equal to the outer diameter of a pipeline from a water inlet to a water outlet, a third groove which is perpendicular to the second groove is formed in one end of the second groove, and the third groove is used for positioning an outer hexagon nut of the water outlet;
the second clamping block and the first clamping block are in mirror symmetry.
Furthermore, the bottom of the second groove is also provided with a positioning groove, and the length and the width of the positioning groove are equal to those of the indication arrow of the one-way valve.
Furthermore, an inner hexagon matched with an outer hexagon nut of the water outlet is arranged in the third groove.
Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:
the first clamping block and the second clamping block of the fixture are matched with each other, and each groove structure is matched with a drain hole pipeline, a water inlet pipeline to a water outlet pipeline, a water outlet outer hexagon nut and a control port pipeline of the one-way valve respectively, so that the fixture can fix the valve body when the valve body of the one-way valve is machined, and the problem that the valve body machining is influenced due to transverse or rotary motion of the valve body is avoided.
Drawings
Fig. 1 is a schematic structural view of a first clamping block of the present invention;
in the drawings: 10-a first groove, 11-a second groove, 12-a positioning groove, 13-a third groove and 14-a first clamping block.
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 check valve clamp includes a first clamp block 14 and a second clamp block in mirror symmetry;
the first clamping block 14 is a semicircular ring body, the inner diameter of the first clamping block is equal to the outer diameter of a control port pipeline, a semicircular first groove 10 is formed in one side of the lower portion of the first clamping block 14, the radius of the first groove 10 is the same as the outer diameter of a drain hole pipeline, a semicircular second groove 11 parallel to the first groove 10 is formed in the upper portion of the first clamping block, the radius of the second groove 11 is equal to the outer diameter of a pipeline from a water inlet to a water outlet, a third groove 13 perpendicular to the second groove 11 is formed in one end of the second groove 11, and the third groove 13 is used for positioning an outer hexagon nut of the water outlet. Wherein the first groove 10, the second groove 11 and the third groove 13 are respectively matched with a drain hole pipeline, a pipeline from a water inlet to a water outlet and an outer hexagon nut of the water outlet of the one-way valve. Since the first clamping block 14 is a semi-circular ring, a semi-circular hollow area is arranged inside the first clamping block, and a control opening pipeline of the check valve is matched with the semi-circular hollow area.
When the clamp is actually used, the valve body of the check valve is placed into each groove correspondingly, and then the second clamping block is closed, so that the machine can be machined.
In addition, since the valve body of the one-way valve has an indicating arrow, in order to enable the first clamping block 14 and the second clamping block to completely clamp the valve body of the one-way valve, a positioning groove 12 is further arranged at the bottom of the second groove 11, and the length and width of the positioning groove 12 are equal to those of the indicating arrow of the one-way valve. An inner hexagon matched with the outer hexagon nut of the water outlet is arranged in the third groove 13.
