Embodiment Construction
[0019] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0020] Depend on figure 1 to combine figure 2 As shown, a plastic-lined regulating valve includes a valve body 1, a valve cover 2, a valve disc 3 and a valve stem 4. The valve body 1 is provided with a medium channel 11, and the valve disc 3 and the valve stem 4 Connected and inserted into the medium passage 11 of the valve body 1, the inner wall of the valve body 1 is provided with a first plastic lining layer 5, the valve flap 3 is provided with a second plastic lining layer 6, and the valve flap 3 is provided with a second plastic lining layer 6. The flap 3 has a first position where it is opened so that the medium channel 11 is conducted and a second position where it is closed so that the first plastic lining layer 5 and the second plastic lining layer 6 are in contact. The valve stem 4 is covered with a telescopic tube 7 , the telescopic tube 7 is a...

The invention discloses a plastic-lined adjusting valve. The problem that an existing adjusting valve is not reliable in sealing is solved. The plastic-lined adjusting valve comprises a valve body, avalve cover, a valve clack and a valve rod, wherein a medium channel is arranged in the valve body, the valve clack and the valve rod are connected and are inserted into the medium channel of the valve body, a first plastic-lined layer is arranged on the inner wall of the valve body, a second plastic-lined layer is arranged outside the valve clack, and the valve clack has a first position and a second position, when the first position is opened, the medium channel can be connected, and when the second position is closed, the first plastic-lined layer and the second plastic-lined layer are attached; and a telescopic pipe is arranged outside the valve rod in a sleeving mode, and the telescopic pipe is attached to the plastic-lined layers. According to the plastic-lined adjusting valve, the telescopic pipe and the second plastic-lined layer are arranged, so that the valve rod is not in contact with the medium, the medium is not prone to leakage from the valve rod, the sealing effect of the product is good, in the vertical movement process of the valve rod, the telescopic pipe can stretch and retract reliably, the position of the valve rod is not prone to leakage in the movement process and can be reliably attached to the second plastic-lined layer, so that the product sealing effect is good.
Description
technical field [0001] The invention relates to a regulating valve, in particular to a plastic-lined regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, is the final control element that changes the process parameters such as medium flow, pressure, temperature, liquid level, etc. by means of power operation by receiving the control signal output by the adjustment control unit. Generally, it is composed of an actuator and a valve. According to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; according to the power used by the actuator, it can be divided into three types: pneumatic regulating valve, electric regulating valve and hydraulic regulating valve. According to its functions and characteristics, it is divided into three types: linear characteristics, equal percentage characteristics and parabolic characteristics. ...
