Abstract
The utility model relates to a plunger piston valve, which mainly comprises a valve body (1), a valve cover (2), a valve rod (3), a plunger piston (4), a hole frame (5), a sealing ring (6) and a hand wheel (7), wherein the valve cover (2) is arranged on the valve body (1) and is fixed through a screw bolt (8), the sealing ring (6) is arranged between the valve cover (2) and the valve body (1), the valve rod (3) is arranged in the middle of the hole frame (5), the upper end of the valve rod (3) is connected with the hand wheel (7), and the plunger piston (4) is arranged at the lower end of the valve rod (3). The utility model is characterized in that a regulating screw (3) is arranged on the hand wheel (7), the sealing ring (6) is formed by a two-layer structure, and adopts novel nontoxic sealing materials with high elasticity and high abrasion resistance, the sealing is reliable, and the utility model is durable in use.
Description
Technical field
The utility model relates to a kind of valve, refers more particularly to a kind of plunger valve.
Background technique
The general employing firmly of existing plunger valve seals, and the valve rod place is provided with filler, and leakage phenomenon in use easily takes place.Adopting flexible nonmetal sealing is a kind of more satisfactory sealing at present.But generally complicated with the structure of the corresponding plunger of this sealing means, the adjustment process of sealing operation simultaneously is cumbersome, damages seal ring when regulating easily by pressure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of novel plunger valve of simple in structure, easy to operate, good seal performance is provided.
The utility model is realized in the following way:
A kind of plunger valve mainly includes valve body 1, valve gap 2, valve rod 3, plunger 4, hole frame 5, seal ring 6, handwheel 7; Valve gap 2 is located on the valve body 1, and is fixing by bolt 8, between be provided with seal ring 6, valve rod 3 is located in the middle of the hole frame 5, its upper end is connected with handwheel 7, plunger 4 is located at the lower end of valve rod 3; It is characterized in that: described handwheel 7 is provided with an adjusting screw 3, and described seal ring 6 is made up of double-layer structure.
There is individual inclined-plane a the lower end of described plunger 4, and matches with the inclined-plane a ' of sealing on the elastic ring 9.
Described plunger 4 and 9 of sealing elastic rings adopt interference fit.
When the handwheel rotation, drive the open and close function that plunger pumps and finishes valve in the middle of the frame of hole by valve rod.In valve, adopt interference fit between plunger and seal ring, by regulating flange bolt in the gland, lateral force and valve body mesopore face and the sealing of plunger cylindrical that the seal ring compression is produced, thereby guaranteed the sealing of valve, stopped internal and outernal leakage, simultaneously valve opening moment is little, can realize the rapid opening and closing of valve.Can regulate control to the sealing elastic ring by adjusting screw.
In sum, the novel plunger valve of simple in structure, easy to operate, the good seal performance of the utility model.
Description of drawings
Fig. 1 the utility model structural representation;
Embodiment
Now in conjunction with the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1, a kind of plunger valve mainly includes valve body 1, valve gap 2, valve rod 3, plunger 4, hole frame 5, seal ring 6, handwheel 7; Valve gap 2 is located on the valve body 1, and is fixing by bolt 8, between be provided with seal ring 6, valve rod 3 is located in the middle of the hole frame 5, its upper end is connected with handwheel 7, plunger 4 is located at the lower end of valve rod 3; It is characterized in that: described handwheel 7 is provided with an adjusting screw 3, and described seal ring 6 is made up of double-layer structure.
There is individual inclined-plane a the lower end of described plunger 4, and matches with the inclined-plane a ' of sealing on the elastic ring 9.
Described plunger 4 and 9 of sealing elastic rings adopt interference fit.
Because plunger surface processes through high-precision cylindrical grinder.Seal ring adopts the nontoxic sealing material that elasticity is strong, wear resistance is high, so sealing is reliable, durable in use.Thereby improved the working life of plunger valve.
When the handwheel rotation, drive the open and close function that plunger pumps and finishes valve in the middle of the frame of hole by valve rod.In valve, adopt interference fit between plunger and seal ring, by regulating flange bolt in the gland, lateral force and valve body mesopore face and the sealing of plunger cylindrical that the seal ring compression is produced, thereby guaranteed the sealing of valve, stopped internal and outernal leakage, simultaneously valve opening moment is little, can realize the rapid opening and closing of valve.Can regulate control to the sealing elastic ring by adjusting screw.
Claims (3)
