Abstract
The utility model relates to a fitting for a hot water pipeline valve, and discloses a plugging head for a pipeline valve of a solar water heater. The plugging head structurally comprises a plugging rod and a head part which are connected together, wherein threads are formed on the surface of the plugging rod, the other end of the head part is connected with a rectangular block, and the cross section of the rectangular block is rectangular. During mounting and dismounting, a spanner is used for clamping the rectangular block and rotates, and accordingly, the plugging head can be mounted on the pipeline valve or dismounted from the pipeline valve. The spanner can increase the moment of force during operation, accordingly, the operation is more labor-saving while compared with the use of a screw driver, and neither mounting nor dismounting can be influenced by water scale or rusting.
Description
Technical field
The present invention relates to mechanical field, be specially a kind of accessory for the hydro-thermal pipeline valve, especially a kind of valve pipe block head for solar water heater.
Background technique
Solar water heater need to check and clears up its pipeline valve in routine use, therefore, usually can at the pipeline valve place of solar water heater pipe laying valve plug, namely on pipeline or valve, through hole be set, above plug is arranged on.During the maintenance cleaning, plug is removed and get final product.
The structure of solar energy water heater pipe valve pipe block head generally comprises shutoff bar and the head that links together, and there is screw thread on shutoff bar surface, and the screw thread coupling with in the pipeline valve through hole can screw in the shutoff bar in through hole, make it sealing.Head operated by rotary motion at block head arranges cross or the yi word pattern groove, and available cross or slotted point screwdriver carries out dismounting.
But block head is after long-term the use, and because of reasons such as build-up of limescale and erosions, groove can or produce corrosion by the incrustation scale shutoff, causes groove and screw-driver not to mate, and is difficult to dismounting; And screw-driver moment is less, and when long or size is larger when block head, operation is more time-consuming and painstaking.
Therefore need to be improved prior art, be made it to be easy to dismounting.
The model utility content
The present invention aims to provide a kind of valve pipe plug for solar water heater.
This solar energy water heater pipe valve block head, its structure comprises shutoff bar and the head that links together, and the cross section of shutoff bar is circular, and shutoff bar surface arranges screw thread; The other end of head connects rectangular block, and the cross section of rectangular block is rectangle.The height of rectangular block is preferably 10～35mm, and the diameter of shutoff bar is preferably 5～30mm.
When the cross section of head was circle, the length of rectangular block cross section was 3/4～a times of head diameter, and width is 1/4～3/4 of head diameter.Preferably, the width of rectangular block cross section is 1/3～2/3 of head diameter.
If the head cross section is oval, one side that the rectangular block cross section is grown is parallel with major diameter, and shorter one side is parallel with oval minor axis; The length on long limit is a times of major diameter, and the length of minor face (being width) is 2/3 of oval minor axis.
Block rectangular block and rotate with spanner during installation and removal, block head can be arranged on pipeline valve or remove.Moment when using spanner can increase operation, operation is than using the laborsaving convenience of screw-driver like this.And can be because of incrustation scale and corrosion and affect dismounting.

Embodiment
Embodiment 1
As shown in Figure 1, a kind of solar water heater 1, its structure comprises pipeline 3 and some heater bands 2, perforate on pipeline, and valve pipe block head 4 is set in the hole, so that the cleaning pipeline.
As shown in Figures 2 and 3, the structure of this valve pipe block head comprises shutoff bar 401 and the head 403 that links together, and screw thread 402 is set on the shutoff bar, and the length of screw thread is less than the length of shutoff bar.The cross section of head is circular, and at the opposite side connection rectangular block of head, the cross section of rectangular block is rectangle, and the length of rectangular block cross section is a times of head diameter, and width is 3/5 of head diameter.
If the head cross section is oval, one side that the rectangular block cross section is grown is parallel with major diameter, and shorter one side is parallel with oval minor axis; The length on long limit is a times of major diameter, and the length of minor face (being width) is 2/3 of oval minor axis.
The cross section of shutoff bar is circular, and diameter is 20mm.The height of rectangular block is 25mm.
During installation with the gasket sleeve of annular on the shutoff bar, be placed on head, block rectangular block and rotate with spanner, block head is arranged on pipeline valve.Block rectangular block and backward rotation with spanner during dismounting, block head can be pulled down.Moment when using spanner can increase operation, operation is than using the laborsaving convenience of screw-driver like this.
The comparative example
Traditional solar water heater valve pipe block head, its structure comprise shutoff bar 401 and the head 403 that links together, and screw thread 402 is set on the shutoff bar, as shown in the A and B of Fig. 4.As shown in Figure 5, arrange cross on head or the yi word pattern groove, available cross or slotted point screwdriver carries out dismounting.
