Abstract
The utility model relates to a kind of flange and connects regulating plunger stop valve, there is valve body, on described valve body, be provided with the valve gap coordinating with valve body, between valve body and plunger, be provided with flexible sealing ring, the resilience of flexible sealing ring is strong, and sealability is unique in leaking, the lumen centers position of valve body is provided with plunger, on plunger, be provided with valve rod, on valve rod, be connected with handwheel, on the appearance limit of valve body, be coated with anti-corrosion layer.The utility model science simple in structure, safe and reliable, opens and closes especially easily dexterously, and rapid operation, opens and closes light, soon, and sealability is unique improves the using scope of product without leaking, high temperature resistant, corrosion-resistant, resilience is strong, and maintain and replace is simple.
Description
Technical field
The utility model relates to a kind of flange and connects regulating plunger stop valve.
Background technique
Plunger stop valve is the modification of conventional stop valve, and in this valve, flap and valve seat are normally based on plunger principle design.Flap polishes into plunger and is connected with valve rod, sealing is to be realized by two elastic seal rings that are enclosed within on plunger, two elastic seal rings separate with a collar, and by the load being applied to by bonnet nut on valve gap, plunger seal ring is around fastened, elastic seal ring can be changed, and can adopt various materials to make, and this valve is mainly used in " opening " or " pass ", but have the plunger of special form or the special collar, also can be for adjust flux.
The stop valve Safety performance of using is now poor, open and close difficultly especially, complicated operation, exists safety to go back, sealability is poor, be prone to leakage situation, cause product normally to use, reduce manufacturing efficiency, the using scope of product is narrower simultaneously, high temperature resistant, corrosion-resistant, resilience is all poor by force, needs often maintenance and changes, and increases cost of production.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of flange high temperature resistant, corrosion-resistant, that resilience is strong to connect regulating plunger stop valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of flange connects regulating plunger stop valve, there is valve body, on described valve body, be provided with the valve gap coordinating with valve body, between valve body and plunger, be provided with flexible sealing ring, the resilience of flexible sealing ring is strong, and sealability is unique in leaking, the lumen centers position of valve body is provided with plunger, on plunger, be provided with valve rod, on valve rod, be connected with handwheel, on the appearance limit of valve body, be coated with anti-corrosion layer.
Further, with bolts between described valve body and valve gap.
Further, between described plunger and valve rod, by post nut, be connected, the pretightening force by adjusting nut opens and closes especially easily dexterous, and rapid operation, opens and closes light, fast.
Further, described valve body adopts metal stainless steel to make, and valve body has good resistance to high temperature, extends the working life of product, reduces costs.
The beneficial effects of the utility model are: the utility model science simple in structure, safe and reliable, opens and closes especially easily dexterity, rapid operation, open and close gently, soon, sealability is unique in leaking, the using scope of raising product, high temperature resistant, corrosion-resistant, resilience is strong, maintain and replace is simple.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. valve bodies in figure, 2. valve gap, 3. plunger, 4. valve rod, 5. handwheel, 6. bolt, 7. post nut, 8. flexible sealing ring, 9. anti-corrosion layer.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of flange as shown in Figure 1 connects regulating plunger stop valve, there is valve body 1, on valve body 1, be provided with the valve gap 2 coordinating with valve body 1, between valve body 1 and plunger 4, be provided with flexible sealing ring 8, the lumen centers position of valve body 1 is provided with plunger 3, on plunger 3, be provided with valve rod 4, on valve rod 4, be connected with handwheel 5, on the appearance limit of valve body 1, be coated with anti-corrosion layer 9, between valve body 1 and valve gap 2, adopt bolt 6 to be connected, between plunger 3 and valve rod 4, by post nut 7, be connected, valve body 1 adopts metal stainless steel to make.
It is concrete when handwheel 5 rotates, by valve rod 4, drive plunger 3 in the middle of valve body 1, to pump the open and close function of valve, between plunger 4 and flexible sealing ring 8, adopt interference fit, by adjusting bolt pretightening force, lateral force and valve body 1 mesopore face plunger 4 cylindrical sealings that flexible sealing ring 8 compressions are produced, thereby guaranteed the sealing of valve, stopped internal leakage.Because flexible sealing ring 8 adopts rebound elasticity strong, the nontoxic sealing material that wear resistance is high, so sealing is reliable, durable in use.Thereby improved the working life of valve.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
