Abstract
The utility model relates to a plunger-type valve, which comprises a valve body, a valve rod, a plunger, a valve base, a transmission mechanism, a seal part and a fixing part, the valve base and the plunger have a coordinated conical sealed curved surface, the key point is a soft sealing plunger ring is arranged on the sealing surface of the plunger, the soft sealing plunger ring is arranged between the plungers, a soft and a hard multilayer sealing structure is formed between the plunger sealing surface and the valve base sealing surface, soft sealing structure is in the middle of the hard sealing structure which has two layers upper and lower, the soft sealing structure has the advantages of suitable for high temperature and good sealing performance. Furthermore, the soft sealing plunger ring is suppressed in the plunger directly, thus the structure is simple, and additional leakage point is avoided. The plunger-type valve is applicable to be on-off switches which are used for the high temperature, high sealing requirement industrial pipeline.
Description
Technical field
The utility model relates to a kind of valve that is used for pipe switch, specifically about a kind of plunger valve.
Background technique
Plunger valve generally is made up of valve body, valve rod, valve gap, plunger, valve seat, driving mechanism, Sealing and assembling set etc., and valve seat and plunger have the cone seal curved surface that cooperatively interacts, and this cone seal curved-surface structure has this valve and opens and closes light advantage.But the plunger valve of existing structure, its sealing configuration are by soft seal ring on the plunger and sealing surface of seat fitted seal, are simple soft sealing structure, and serviceability temperature is lower, sealability is relatively poor.In addition, the soft seal ring is fitted on the plunger by a gland, has increased leakage point between gland and soft seal ring, reduces the sealability of valve, and complex structure.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of good seal performance, serviceability temperature height, light wear-resisting plunger valve simple in structure are provided.
The technological scheme that realizes the utility model purpose comprises valve body, valve rod, valve gap, plunger, valve seat, driving mechanism, Sealing and assembling set, valve seat and plunger have the cone seal curved surface that cooperatively interacts, its key is that the soft sealing plunger ring is set on the plunger seal face, this soft sealing plunger ring is arranged in the middle of the plunger, makes plunger and valve seat constitute hard, soft double seal.
The utility model advantage compared with prior art is: plunger and valve seat constitute hard, soft double seal, make and constitute hard soft alternate multi-layer sealing structure between plunger seal face and the sealing surface of seat, soft sealing structure makes valve Applicable temperature height, good seal performance in the centre of two-layer hard sealing structure up and down.In addition, the soft sealing plunger ring directly is compressed in the plunger, and is simple in structure, avoids additional leakage point.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Plunger valve as shown in Figure 1, comprise valve body 1, valve rod 10, valve gap 9, plunger 2, valve seat 4, driving mechanism, Sealing and assembling set, valve seat 4 has the cone seal curved surface that cooperatively interacts with plunger 2, on plunger 2 sealing surfaces, soft sealing plunger ring 3 is set, this soft sealing plunger ring 3 is arranged in the middle of the plunger 2, makes plunger 2 and valve seat 4 constitute hard, soft double seal.In the present embodiment, plunger 2 is provided with twice soft sealing plunger ring 3, makes and forms three road hard sealing structures and twice soft sealing structure between plunger 2 sealing surfaces and the sealing surface of seat.Plunger 2 is connected on the valve rod 10 by trip ring 5 and nut 6, and valve gap 9 is connected with valve body 1 with nut 8 by bolt 7.Bedding and padding ring 12, bedding and padding 13 between valve gap 9 and valve rod 10 are press-fited by gland 14, and frame is connected by bolt 11 valve gaps 9.Between frame and handwheel transmission device 16, be provided with bearing 15, between handwheel transmission device 16 and the valve rod 10 and cap 17 and nut 18 fixing.
