Push rod.
Further, in order to improve the sealing between valve rod and bonnet, it is additionally provided between the valve rod and bonnet
Packing box assembly, the packing box assembly includes the lower liner, filler, the gland that set gradually from the bottom to top, in described filler
The first O-ring is provided between gland and valve rod and between gland and bonnet.
Further, pressing plate is provided with above described filler letter component, the pressing plate is fixed with bonnet by bolt and connected
Connect.
Further, it is fixedly connected by connecting bolt between the bonnet and valve body.
By said structure, the position of fairlead, valve element and valve seat in valve body is withstood using bonnet, and ensure
Liquid in valve body does not spill over, and plays good sealing effectiveness.
Further, for the ease of installation and the more preferable sealing for ensureing valve body, the top edge of the fairlead is outside
Side extends to form boss, and the boss is connected between the valve body and bonnet, and saw is provided with the both sides up and down of the boss
Tooth pad.
Further, there is good sealing in order to ensure executing agency, is provided between the piston and cylinder body
The O-ring of brightness second, the 3rd O-ring is provided between first push rod and the bottom end cover.
Remarkable result of the present utility model is：Spring assembly and executing agency be there occurs into change on traditional structure, i.e.,
Spring assembly in upper, executing agency under, while the requirement of conventional pressure adjustable type regulating valve is met, realize valve body and
The versatility of spool parts, the degree of product standardization is high, reduces use cost.
