Embodiment Construction

[0026] Preferred embodiments are provided below to make the technical solution and beneficial technical effects of the present invention clearer and clearer to those skilled in the art. However, the practice of the present invention is not limited to the following examples. Nor does it prove that the formulation of the invention is the only specific requirement.

[0027] Sheet molding compound (SMC) formulation (weight ratio):

[0028]

[0029]

[0030] production method:

[0031] Stir and mix the raw materials other than glass fiber with a high-speed disperser, and then soak the short glass fiber to make a sheet covered with PE film on both sides; the glass fiber needs to be treated with a silane coupling agent first;

[0032] The sheet was thickened at 40°C for 48 hours to form a semi-tacky sheet-shaped sheet molding compound;

[0033] Tear off the PE films on both sides of the material, put them into the special metal mold of the present invention heated to 110-115...

Abstract

The invention relates to a water meter well made of plastic, and aims to provide a plastic water meter well convenient to machine and use. The water meter well comprises a well body with the bottom sealed, and the bottom of the well body protrudes to the inner side of the well body to form at least one boss, and the two bosses are oppositely arranged. The plastic is made of 60-65 parts of unsaturated polyester, 30-35 parts of polystyrene, 0-2 parts of mold release, 1 part of MgO powder, 1 part of benzamide, 2 parts of tert-butyl peroxy-2-ethylhexanoate, 3 parts of zinc stearate, 200-230 parts of calcium carbonate and 100-110 parts of short glass fiber, wherein the MgO powder is made to pass through a 400-mesh sieve. The plastic water meter well is durable in use, resistant to corrosion and low in cost. The water meter well with the bosses is convenient to install, use and maintain. Performance of the new plastic is superior, a machining and manufacturing process and equipment are further simplified, and machining efficiency is improved.

Description

technical field [0001] The invention relates to water supply and drainage facilities, in particular to a water meter well made of plastic and used in tap water supply and other similar occasions. Background technique [0002] In order to measure tap water users, tap water meters are installed on the tap water pipes. Then a plurality of water meters are all installed in the same water meter well in order to facilitate meter reading and maintenance. That is, a main pipe is divided into multiple branches through multiple water meters and branch pipes, and the water flow of each branch is measured by the water meter. The connections between these water meters and main pipes and branch pipes are located in the water meter wells. [0003] Existing water meter wells are usually of brick structure, which has low construction efficiency and is not corrosion-resistant. The water meter well of plastic material appeared on the market afterwards, as shown in the outward appearance des...
