Example Embodiment

[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0016] Such as figure 1 Shown:

[0017] A stainless steel pressure control valve includes a valve seat 1, a valve body 2 and a valve cover 3 arranged in sequence from bottom to top. A fluid inlet 4 is provided on one side of the lower part of the valve seat 1, and a fluid outlet 5 is provided on the other opposite side. The upper part of the valve seat 1 is provided with a cavity 6 and the lower part is provided with ...

Abstract

The invention discloses a stainless steel pressure control valve. The stainless steel pressure control valve comprises a valve base, a valve body and a valve cover. A fluid inlet and a fluid outlet are formed in the lower portion of the valve base. A compression spring and a valve element are arranged inside the valve base from bottom to top in sequence. The lower portion of the valve element is a cone. The valve element is sleeved with a hard sealing base and a soft sealing base. A gap or sealed state can be formed between the valve element and the soft sealing base through the cone. A valve element base and a membrane are installed at the upper portion of the valve element. A round hole is formed below a cavity in the upper portion of the valve base and communicated with the fluid outlet. The valve body and the valve cover are internally provided with communicated cavities internally provided with a large spring base, a large spring and a small spring base from bottom to top in sequence. The large spring base is clamped to the lower portion of the valve body. A screw rod is arranged at the upper portion of the valve cover. The lower portion of the screw rod penetrates through the valve cover and is fixedly connected with the small spring base, and a handle is arranged at the upper portion of the screw rod. The stainless steel pressure control valve is simple in structure, good in sealing effect and stable in performance, and when medium flow suddenly changes, the stability of the pressure of a rear pipeline of the valve body can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of LED production, in particular to a stainless steel pressure control valve for LED production. Background technique [0002] Due to its obvious advantages, such as small size, low voltage, long service life, high brightness, low heat, and environmental protection, LEDs have gradually increased their market usage. [0003] In the production process of LED, the raw material gas is toxic. In order to protect the workers and determine the safety of LED students, it is necessary to effectively prevent the leakage of toxic gas. The pressure control valve is an important part of whether there will be toxic gas leakage during the production process, so it is necessary for the pressure control valve to produce LEDs to work safely and effectively. [0004] Ordinary pressure reducing valves have the problem of easy leakage to cause personal injury and casualties. The working process of an ordinary pressure control ...
