Abstract
The utility model discloses a wear-resistant chlorine stop valve with a long service lifetime, which comprises a valve body. The lower end of the valve body is provided with an inlet channel and an outlet channel. The upper end of the valve body is provided with a valve cover. A valve stem is disposed in the valve body. A sealing filler and a pressure plate are disposed between the valve stem and the valve cover. The lower end of the valve rod between the inlet channel and the outlet channel is provided with a valve clack. The upper end of the valve stem is provided with a hand wheel. The outer side of the valve stem disposed at the upper end of the sealing filler is sleeved by a plastic lining, and the plastic lining is fixed to the valve stem through the pressure plate. The wear-resistant chlorine stop valve is advantageous in that during the using process, no friction will occur between the valve stem and the valve cover; service lifetime of the valve stem is prolonged, and sealing effect is enhanced.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of wear-resisting chlorine stop valve.
Background technique
Wear-resisting chlorine stop valve is the valve a kind of commonly used that is used for deep-etching flowing mediums such as control and adjusting chlorine in the chemical industry.The structure of existing wear-resisting chlorine stop valve comprises: valve body, inlet passage and outlet passage in the lower end of valve body, upper end at valve body is provided with valve gap, inside at valve body is provided with valve rod, between valve rod and valve gap, be provided with stuffing box packing and pressing plate, the outside, lower end at valve rod is welded with bellows, and the lower end of valve rod is provided with flap between inlet passage and outlet passage, is provided with handwheel in the upper end of valve rod.During use, wear-resisting chlorine stop valve is installed in the pipeline, drives valve rod, flap lifting by handwheel, thus the connection that realizes inlet passage and outlet passage with close.In the using process, valve rod easily and occur friction between the valve gap damages valve rod, and working life is shorter.
Summary of the invention
Technical problem to be solved in the utility model is: the wear-resisting chlorine stop valve that a kind of long service life is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: wear-resisting chlorine stop valve, comprise: valve body, inlet passage and outlet passage in the lower end of valve body, upper end at valve body is provided with valve gap, inside at valve body is provided with valve rod, between valve rod and valve gap, be provided with stuffing box packing and pressing plate, the lower end of valve rod is provided with flap between inlet passage and outlet passage, upper end at valve rod is provided with handwheel, the outside at described stuffing box packing upper end valve rod is arranged with plastic bushing, and plastic bushing is fixed on the valve rod by pressing plate.
The utility model has the advantages that: above-mentioned wear-resisting chlorine stop valve, in the using process, valve rod not can and valve gap between friction appears, prolonged the working life of valve rod, increased sealing effect.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the wear-resisting chlorine stop valve of the utility model.
Among the figure: 1, valve body, 2, inlet passage, 3, outlet passage, 4, valve gap, 5, valve rod, 6, stuffing box packing, 7, pressing plate, 8, flap, 9, handwheel, 10, plastic bushing.
Embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, wear-resisting chlorine stop valve, comprise: valve body 1, inlet passage 2 and outlet passage 3 in the lower end of valve body 1, be provided with valve gap 4 in the upper end of valve body 1, be provided with valve rod 5 in the inside of valve body 1, between valve rod 5 and valve gap 4, be provided with stuffing box packing 6 and pressing plate 7, the lower end of valve rod 5 is provided with flap 8 between inlet passage 2 and outlet passage 3, be provided with handwheel 9 in the upper end of valve rod 5, the outside at described stuffing box packing 6 upper end valve rods 5 is arranged with plastic bushing 10, and plastic bushing 10 is fixed on the valve rod 5 by pressing plate 7.
During use, wear-resisting chlorine stop valve is installed in the pipeline, drives valve rods 5, flap 8 liftings by handwheel 9, thus the connection that realizes inlet passage 2 and outlet passage 3 with close.
In the using process, plastic bushing 10 can prevent from occurring friction between valve rod 5 and the valve gap 4, has prolonged the working life of valve rod 5, has increased sealing effect simultaneously.
