Valves are widely used in various areas of the national economy and to adapt to the requirements of a variety of different conditions, 200X pressure reducing valve and thus its variety and a huge number. Valve manufacturing in China is enormous, thousands of valve manufacturers throughout the country, China has become one of the largest global valve production and market demand. China\\ s valve industry, mostly small and medium-sized enterprises, mixed 300X slow closing check valve, the annual output value exceeding 100 million yuan less than 10, even compared with other domestic machinery industry, whether on the equipment or technical level, there are also very a large gap between the real ability of independent research and development of high-end products unit rarely so large petrochemical, nuclear, oil & gas transmission pipeline and other major projects, 300X700X pump control valve of the valve supporting mainly rely on imports.

Valve enterprises attach great importance to the development of new products. It should be noted that China\\ s valve industry today, 500X pressure relief there are still gaps to hold the valve with the international advanced level, but has gone beyond simply copy the absorption stage. To seek further development of the technology the way it should be in the analysis of foreign advanced products at the same time, from a deeper level of valve technology development trends and product development towards a comprehensive analysis and thinking, efforts to develop the 100X piston remote control float valve new products with independent intellectual property rights.

People-oriented, to establish a user-friendly product design philosophy. Usually the main consideration in product design elements of the 100A-angle fixed water level valve material, structural, mechanical strength, performance, service life, the general also use these indicators in the evaluation of the pros and cons of the valve. With the development, social progress, people-oriented ideas have penetrated into various fields of social life, we feel this change from the housing, cars, computers, cell phones, clothing and a variety of public facilities can 100X remote control float valve from the many aspects of the safety, comfort, energy saving, environmentally friendly, innovative, beautiful in every detail, nuanced account of the consumer experience, reflect on care. Clear, user-friendly design should not be confined to the scope of consumer goods, a wide range of the valve as a large, widely used in industry, agriculture, national defense and people\\ s daily work and life are closely related to mechanical products, can not always is limited to the traditional design concepts and design methods, but should explore new ideas, diaphragm type remote control float valve to inject new ideas.

When the analysis of foreign advanced products, in addition to the technical performance indicators, will be noted that its beautiful shape, compact structure, the cavity is clean and elegant details piston-type remote control float valve. For example, in order to prevent secondary pollution, sewage valve does not use asbestos packing and gasket sealing. Another example is to avoid the hand of the operator is scratched, the flange connecting bolts ends are processed into arc, etc., the differences in these specific details, it should lead us to a deeper level of thought: of KPF-16-type balancing valves why To do this? Think of how it do this? Conclusions can not be attributed to the user-friendly design concepts go, to understand from this level up, it will no longer stay in a simple first stage of our product design, but from an ergonomic point of view, more secure, reliable, energy saving, environmental protection, clean production, operating comfort and convenience, easy disassembly and maintenance study many aspects of thinking, to give the valve the traditional products ZSJZ flow indicator with a new concept and image, formed its own characteristics.

    In the gas tank to install a valve, it will not leak to ensure their safety? New Year period, the two claimed to be commissioned by

the staff of gas street, big sell to the public this "safety valve." Reporter yesterday from the gas company in Shijiazhuang City,

confirmed that the company has never had to sell to the public safety valve, the majority of users to guard against fraud.

    According to a district west Leung introduced the afternoon of January 3, at home, suddenly a man and a woman, the other gas

equipment companies claiming to be the staff, the company and the city gas company signed an agreement, uniform for users to

install gas the safety valve. "They said that only a general gas valve, not enough to guarantee safety, the safety valve is installed, you

can ensure that the gas does not leak so safe." Leung told reporters, usually the mother alone at home cooking and more , listening

to the other side of this valve introduces high security, so they move the heart to spend 108 yuan installation of a "safety valve."

    However, after installation the valve formal invoice issued by the other party has not only provided a receipt and then left. Leung

soon found that receipt of the seal is not "gas company", but at a certain gas distribution equipment, and seals also appeared on the

actually spelling, including "burning" not a word is the word next to the fire. "If it is a regular official seal, may be spelling it how?" Ms

Leung then go out to recover quickly, but the other had not disappeared. Leung later learned from the neighbors, each other and

there is no "house to house" of publicity, but only a few households selected for each building door to door. For the so-called "safety

valve" is safe or not, Ms Leung did not mind the end: "After all, gas is not a joke, if installed, there are security risks and inferior

products, may be how to do ah?"

    At the same time, who lives in a high column, Ms. Lu district to call the newspaper, said that during the holiday season was the

name of the gas company to install the safety valve of the district, many residents to buy this valve.

    Afterward, the reporter repeatedly on the receipt by the other side of the phone trying to contact, but the phone number still

can not connect. Yesterday morning this reporter consulted the Shijiazhuang city gas companies. The company s staff, the company

has never been any unit or individual agreement, nor who will be commissioned to sell products door, so Ms Leung, who is certainly

not encountered gas company s regular staff or cooperative units.

    In addition, the staff told reporters that are equipped with pressure relief valve on the gas tank, when the user each time the

ventilation valve for professional staff will check, remind the user needs to be replaced: "the price of a valve about three $ 40, was

not in the hundred or more. "staff, the case against Leung and others, they can go to the ventilation station for a professional

installation of a new" safety valve "for checks, according to choose whether to remove .
