Valve enterprises to have the effect of the end of the “labor shortage” valve key technical standards
Compressive strength performance
The strength performance of the valve refers to the ability of the valve to bear the working pressure of the medium. The valve is to bear the gas pressure of the equipment goods, so it must have sufficient strength and bending stiffness, to ensure that long-term use without cracking or deformation.
Valve sealing performance refers to the valve sealing position blocking medium leakage ability, it is the main technical performance index value of the valve. The sealing position of the valve has three places: the contact between the opening and closing parts and the high-pressure gate valve; Filling material and valve seat and sleeve joint matching; Junction of oil circuit plate and valve cap. In the first part of the leakage is called leakage, which is usually referred to as the closed, it will harm the ability of the valve to disconnect the medium. For disconnect valves, internal leakage is not allowed. The last two leaks are called exposure, that is, the medium leaks from the valve to the outside of the valve. Exposure will lead to raw material damage, environmental pollution, more serious will also lead to safety accidents. For inflammable and explosive items, harmful or radioactive media, exposure is not allowed, so the valve must have stable sealing performance.
Medium through the valve will form pressure damage (both before and after the valve pressure difference), that is, the valve has a certain friction resistance to the fluidity of the medium, the medium to get rid of the valve friction resistance will need to spend a certain amount of kinetic energy. From the consideration of resources, design and production of valves, to minimize the friction resistance of the valve on the flow medium.
Opening and closing force and torque
Opening and closing force and torque are the mutual forces or torques that must be increased to open or close the valve. Turn off the valve, must make open-close part and send a produce certain sealing pressure between the two tu face, at the same time also to get rid of the seat and filling material, among the external thread and nut the seat, seat support in friction and his position at the top of the sliding friction, so be sure to increase must turn off the power and torque, the valve in the opening and closing process, The required opening and closing force and opening and closing torque are variable, and the maximum value is at the final moment of closing or the first moment of opening. Valves should be designed and manufactured to reduce closing force and closing torque.
Opening and closing speed is indicated by the time period required for a single opening or closing position of the valve. General valve opening and closing rate without strict management, but there are some working conditions on the opening and closing rate has special requirements, if some provisions quickly open or close, to prevent safety accidents, some provisions slow off, to prevent water strikes, which should be taken into account in the use of valve types.
Postural sensitivity and stability
This also refers to the valve for the main parameter changes in the medium, to reflect the corresponding vulnerability level. For one-way throttle valve, pressure regulating valve, regulating valve and other valves used to adjust the main parameters of the medium and its valves, steam trap valve and other valves with special role, its sensitivity and stability is a very key technical performance index value.
It shows the solid level of the valve, is the key performance index value of the valve, and has great social and economic practical significance. It is usually indicated by the opening and closing frequency to ensure the tightness standard, and can also be indicated by the service time.
Valve enterprises to have an effect on the end of the “labor shortage”
Valve enterprises to have the effect of year-end labor shortage”
In recent years, every year near the end of this period of time, “labor shortage” like a stubborn disease as regular occurrence, and thus led to a series of related reactions. The valve parts industry chain is more labor-intensive fields, the shortage of human capital immediately leads to the valve parts of many enterprises to reduce production and manufacturing, and even some enterprises dare not blindly accept orders, in order to prevent heart willing and insufficient, resulting in greater damage.
Labor shortage in China is not a new thing, as early as two years ago in the eastern coastal areas and advanced regions of the labor shortage and recruitment difficulties, and 2022 labor shortage comes earlier than usual, fierce, most valve enterprises are worried.
On the analysis of the report, in most of the valve parts enterprises in Our country have the latest production method outdated, low commodity profits, staff demand is large, outdated management concept and other attacks; And in the advanced goods gradually become the future sales market must, important harm enterprise operating profits and survival of the development trend of indoor space, so to play a price war as a market competition to lead the wind part of the valve enterprise, has not a lot of spiritual essence weighing the right of staff. Understanding of talent resources and attaches great importance to the industry or is insufficient, feel just give sufficient wages, independent, is lack of this kind of practice can not work, enterprise talent drain and often the status of departure is more outstanding, the primary factors or lack of agile enterprise recruitment system, the lack of talents and fair communication, On the other hand, such changes also promote enterprises to attach great importance to excellent talents and try their best to retain talents.
In view of the valve industry in Our country, what way can we really keep talents? I think stay only have to pay attention to, want to retain talent, for its obtain capital, their first must have the development plan, let a worker in the enterprise has a long-term goal, have the confidence to follow you, make him except to make ends meet, more major or work, to complete their own ideal life, has a long-term goal, of course, I’ll leave a heart to go, Not only to invest in their own obligations, talent, enthusiasm and youth; And technological innovation, continuous diligence and progress. In addition, it is also necessary to actively build efficient and mutual trust in the corporate culture and art, so that they have ample opportunities to use their own talents and complete their use value.
