National valve standardization technical committee standard review conference held in Zhejiang Cixi decoration accidentally hit crack pipe old master a valve to solve the problem
On September 26, the national Valve standardization Technical Committee standard review meeting was held in Cixi, Ningbo, Zhejiang province. The meeting reviewed the GB/T84642008 iron and copper thread connection valves and other four national standards (English version), and reviewed the preparation template of valve product standards. The review of the standard, the transformation and upgrading of China’s valve industry to guide and play a role.

Valves are widely used, involving various fields such as national defense, infrastructure, industry and agriculture, and domestic and civilian use. Valves are used in all places where gas is used. Because of this, this industrial product is internationally divided into the special equipment camp. For decades, China has gradually become the world’s largest processing plant, the number of China’s valve enterprises is stable in the world.
A few decades ago, when industrial technology was still relatively backward, China relied on imports for safety valves and other products, and even its national standards were based on foreign standards. Until 2007, under the attention and requirements of the National Development and Reform Commission, Zhejiang Chaochao Company and Hefei General Machinery Research Institute successfully drafted the industry standard “Safety Valve for Compressor” JB/T 64412008. With the advent of industry 4.0 era, the processing and manufacturing of valve products will face greater space for development. Valve as a special product, demand industry, quality requirements are also very important. The review of the four national standards of the valve industry at this meeting will further transform and upgrade the industry.
Cixi city has always attached importance to guiding enterprises to take the development road of standard industry. Cixi city in recent years, the implementation of standardization strategy as an important gripper, promoting economic transformation and upgrading of the development of service oriented, to innovation as the power, * * * * boot, social participation, build enterprise as the main body of the standardization work pattern, effectively improve the quality and level standard supply, promote products and technology innovation, power transformation and upgrading of cixi manufacturing. Up to now, a total of 68 enterprises have presided over 164 international, national and industrial standards system revision, of which presided over the formulation of national and industrial standards 74, the total number of ningbo counties and urban areas forefront, 2 enterprises respectively participated in the formulation of lighters and range hoods international standards, creating a precedent in the domestic industry.
Decoration accidentally hit crack pipe old master a valve to solve the problem said that when the decoration of water and electricity is ** may give a problem, ** at the beginning of my letter, unexpectedly my shower decoration, because did not mark the pipeline position in advance, directly hit crack pipe! The master that decorate to my home says, if change word, have to pull down metope, whole root changes ability to go, very trouble. ***, the old master looked back, installed a valve to deal with the problem.
All said that when the decoration of water and electricity is ** may be a problem, ** at the beginning of my letter, but my shower decoration, because there is no early marked pipe position, directly cracked the water pipe! The master that decorate to my home says, if change word, have to pull down metope, whole root changes ability to go, very trouble. ***, the old master looked back, installed a valve to deal with the problem.
The worker says with me, perforation should have been hit in advance before decorating, wait to decorate otherwise in the future, can appear hit crack ceramic tile or hit the case that cracks conduit, whole if change tube, it is trouble very much. It is better to look for the valve that does not have switch, cut the pipeline that cut is split at both ends cut open, replace interface with valve, seal with water mud again next, new shop sticks ceramic tile to go.
Many people are afraid that the valve of this interface will rust, and it is not a problem to apply cement to the future, with a dozen or twenty years. If you are still worried, you can directly buy PPR material interface. However, the deficiency of this repair is that the interface part is very narrow, which may affect the flow rate of water.
There is A common repair method is to use plastic steel soil, with the brothers good about the same, A, B two sides. When repairing water pipes with plastic soil, it is necessary to close all valves to ensure that there is no water pressure. Then smear both sides evenly with warm water, remember that you must soak with warm water and gradually solidify, otherwise it will not stick.
Then wrapped with gauze, such as 24 hours after the water to see whether there is a problem of leakage. If leak, repair again, until do not leak, can wipe cement, stick ceramic tile afresh, ordinary this kind of model steel soil won’t appear a problem inside 10 years. If you want to solidify faster, you can use a hair dryer on the line.
