First, the basic product introduction:
SS-6PNBGM8 imported high pressure needle valve It is a kind of fine-tuning valve. Its valve plug is needle-shaped, which is mainly used to adjust the air flow. 公称口径是1/4-2 ，微调阀要求阀口开启逐渐变大，从关闭到开启能连续细微地调节。 The model of this valve is SS-6PNBGM8, and its nominal diameter is 1 / 4-2 . The fine adjustment valve requires that the opening of the valve gradually increases, and it can be continuously finely adjusted from closing to opening. Needle valve plugs can achieve this function. SS-6PNBGM8 imported high-pressure needle valve plug is generally made of hardened steel long needle, and the valve seat is made of soft materials such as tin and copper. The seal between the valve needle and the valve seat is achieved by the tight fit of its tapered surface. ： 50和60锥角两种，锥表面要经过精细研磨。 The taper of the valve needle has two kinds of taper angles of 1:50 and 60 , and the taper surface must be finely ground. The seal between the valve stem and the valve seat is achieved by a bellows. 进口高压针阀密封填料有PTFE 、 PEEK 、石墨、阀芯阀座密封：堆焊STL 、 PEEK 、 PTFE 、及硬质合金密封。 SS-6PNBGM8 imported high-pressure needle valve sealing packing has PTFE , PEEK , graphite, valve seat seal: surfacing welding STL , PEEK , PTFE , and hard alloy seal. Valves can be selected according to different pressures, temperatures and media. The special structure and corresponding sealing material are used to ensure that the valve will not leak under working conditions, the seal will not deform at the corresponding temperature, and the phenomenon of tight sealing will not occur. The valve core can be cut off and adjusted to cut off by replacing the valve core.
Second, SS-6PNBGM8 imported high-pressure needle valve main parameters:
1. Product model: SS-6PNBGM8
2. Nominal caliber: 1 / 4-2
3. Pressure: 1000Psi-20000Psi
4. Main material: stainless steel
5. Structural form: two pass through, two corner pass, three two pass, three one pass
6. Applicable medium: water, oil, steam, natural gas, petrochemical, etc.
Third, SS-6PNBGM8 imported high-pressure needle valve main features:
1. The needle valve has good sealing performance and long service life. Even if the sealing surface is damaged, you only need to replace the vulnerable parts and you can continue to use it. 进口高压针阀时应使介质的流向与阀体上的箭头方向一致。 When installing the SS-6PNBGM8 inlet high-pressure needle valve, the flow direction of the medium should be consistent with the direction of the arrow on the valve body.
进口高压针阀具有安装拆卸方便、连接紧固、有利于防火、防爆和耐压能力高、密封性能良好等优点，是电站、炼油、化工装置和仪表测量管路中的一种先进连接方式的阀门。 2. SS-6PNBGM8 imported high-pressure needle valve has the advantages of convenient installation and disassembly, fast connection, favorable for fire resistance, high explosion-proof and high pressure resistance, and good sealing performance. It is one of the power stations, oil refining, chemical equipment and instrument measuring pipelines A valve with an advanced connection.
进口高压针阀是一种可以准确调整的阀门用途较广，比如火焰切割用的割距，调整火焰温度的旋钮就是针阀，仪表针阀是仪表测量管路系统中重要组成部分，主要有截止阀和球阀，其功用是作开启或切断管道通路 3, SS-6PNBGM8 imported high-pressure needle valve is a valve that can be accurately adjusted for a wide range of uses, such as the cutting distance for flame cutting, the knob to adjust the flame temperature is the needle valve, the instrument needle valve is an important part of the instrument measurement pipeline system There are mainly stop valves and ball valves, whose function is to open or cut off the pipeline path.
Fourth, SS-6PNBGM8 imported high pressure needle valve anticorrosion method:
1. The main materials of the valve body are stainless steel and carbon steel. The difficulty in selecting the material of the valve body lies in the fact that not only the corrosion problem can be considered, but also the pressure and temperature resistance, whether it is economically reasonable, and whether it is easy to purchase.
2. When the pressure and temperature are not high, using non-metal as the main material of the valve can often prevent corrosion very effectively.
3. Take lining measures, such as lead lining, aluminum lining, engineering plastic, natural rubber and various synthetic rubber. If the media conditions permit, this is a way to save.
进口高压针阀阀体外表面还受到大气腐蚀，一般钢铁材料都以刷漆来防护。 4. In addition, the external surface of SS-6PNBGM8 imported high-pressure needle valve is also subject to atmospheric corrosion. Generally, steel materials are protected by painting.
1. The installation position, height, and inlet and outlet directions must meet the design requirements. Note that the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body.
的规定。 2. The appearance of the valve must be inspected before installation. The nameplate of the valve should comply with the current standard "General Valve Mark" GB 12220 . 及在主干管上起到切断作用的阀门，安装前应进行强度和严密性能试验，合格后方准使用。 For valves whose working pressure is greater than 1.0 MPa and which acts as a cut-off on the main pipe, strength and tight performance tests should be performed before installation, and only qualified after use. 倍，持续时间不少于5min ，阀门壳体、填料应无渗漏为合格。 In the strength test, the test pressure is 1.5 times the nominal pressure, and the duration is not less than 5min . The valve housing and packing should be qualified without leakage. 倍；试验持续的时间符合GB 50243的要求。 During the tightness test, the test pressure is 1.1 times the nominal pressure; the duration of the test meets the requirements of GB 50243 .
