Description

Stainless steel punching press welding type right angle pneumatic valve

Technical field

The utility model relates to a kind of stainless steel punching press welding type right angle pneumatic valve.

Background technique

Pneumatic valve product in the market mostly is to produce in the mode of traditional founding casting, and have following shortcoming: 1. traditional mode of production belongs to high energy consumption, high consumptive material, high pollution, harmful gas directly can be discharged into airborne, very not environmental protection; 2. the manufacture cycle of traditional product is longer; 3. traditional product phenomenons such as sand holes occur easily owing to technologic reason, makes cost of production very high; 4. the product of traditional founding casting is owing to the problem of material, and mostly deal is very heavy, large volume is also just big more more for flow; 5. the field that the product of traditional founding casting is suitable for is also very little, can not directly use in industries such as dyeing machine, food, medicine, chemical industry; 6. traditional product can only be made 180 degree angles owing to reasons such as technologies, must increase a right-angle elbow pipe in use, has increased user cost; 7. in traditional product, the sealing of valve rod and cylinder connection piece active part is to adopt the sealing of O type circle, and the tightness of O type circle sealing is relatively poor, and is easy to wear during use, and working life is short.

The model utility content

The purpose of this utility model provides a kind of stainless steel punching press welding type right angle pneumatic valve, with the high and relatively poor deficiency that waits of sealing of product cost that overcomes prior art.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of stainless steel punching press welding type right angle pneumatic valve, comprise connecting body, valve rod, draft cylinder and valve body, the upper and lower of described connecting body is connected with following fixed cover with last fixed cover by thread connecting mode respectively, fixedly connected with valve body with draft cylinder respectively in the top and bottom of connecting body, the guiding wear ring respectively is equipped with at following fixed cover inside and draft cylinder top, spring and stuffing box packing are equipped with in connecting body inside, and the right side of connecting body is welded with valve, and described connecting body is enclosed within on the valve rod; Fixedly connected with piston by locating stud in the top of described valve rod, Sealing is housed on the piston, and the upper end of valve rod is with spring; The bottom of described valve rod is located in the valve body, and the bottom of valve rod is connected with valve head by locating stud, and the sealing plain cushion is housed on the valve head; One end and the bottom of described valve body respectively are welded with body, and the outer end of body is welded with flange.

The beneficial effects of the utility model are: this product is that punching press, stretching, weldment are assembled, product with compact structure, beautiful shape in light weight, and in the equal volume down-off also greater than the traditional casting product; The use stainless steel is made, and the field that is suitable for is wide, can directly use in industries such as dyeing machine, food, medicine, chemical industry; Pneumatic valve is made 90 degree right angles, and this has just reduced by a right-angle elbow pipe in use, is more convenient for installing and using, and has reduced the cost that uses; The sealing of valve rod and cylinder connection piece active part is to adopt spring to add the structure of tetrafluoro filler, because the effect of spring, tetrafluoro filler under the situation that wearing and tearing are arranged slightly, still can be regulated sealing state automatically to best, thereby prolonged the working life of Sealing, reduced user cost.
