Abstract
The invention relates to a flanged joint adjustable plunger stop valve. The flanged joint adjustable plunger stop valve is provided with valve body. The valve body is provided with a valve deck matched with the valve body. A flexible sealing ring is arranged between the valve body and a plunger. The resilience performance of the flexible sealing ring is high, the sealing performance of the flexible sealing ring is special, and leakage is avoided. The plunger is arranged in the center of an inner cavity of the valve body, a valve rod is installed on the plunger, a hand wheel is connected to the valve rod, and an anti-corrosion layer is sprayed to the outer surface of the valve body. The flanged joint adjustable plunger stop valve is simple and scientific in structure, safe and reliable, especially simple and nimble in opening and closing, light and rapid in opening and closing, special in sealing performance, free of leakage, resistant to high temperature and corrosion, high in resilience performance and easy to maintain and replace, labor is saved during operation, and the use range of a product is widened.
Description
Technical field
The present invention relates to a kind of Flange joint 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 realized by two elastic seal rings be enclosed within plunger, two elastic seal rings collar separates, and by the load be applied to by bonnet nut on valve gap, the seal ring around plunger is fastened, elastic seal ring can be changed, and various material can be adopted to make, and this valve is mainly used in "ON" or "Off", but have the plunger of special form or the special collar, also may be used for adjust flux.
The stop valve Safety performance of present use is poor, open and close hard especially, complicated operation, there is safety should go back, sealability is poor, easily there is 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, need often maintenance and change, increasing cost of production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of high temperature resistant, corrosion-resistant, Flange joint regulating plunger stop valve that resilience is strong.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Flange joint regulating plunger stop valve, there is valve body, described valve body is provided with the valve gap coordinated with valve body, be provided with flexible sealing ring between valve body and plunger, the resilience of flexible sealing ring is strong, the unique No leakage of sealability, the lumen centers position of valve body is provided with plunger, plunger is provided with valve rod, valve rod is connected with handwheel, the appearance limit of valve body is coated with anti-corrosion layer.
Further, with bolts between described valve body and valve gap.
Further, described plunger is connected by post nut with between valve rod, is opened and closed especially easily dexterous, rapid operation by the pretightening force of adjusting nut, 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 invention has the beneficial effects as follows: the simple science of structure of the present invention, safe and reliable, open and close especially easily dexterous, rapid operation, open and close light, fast, the unique No leakage of sealability, improves the using scope of product, high temperature resistant, corrosion-resistant, resilience is strong, and maintain and replace is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. valve bodies, 2. valve gap, 3. plunger, 4. valve rod, 5. handwheel, 6. bolt in figure, 7. post nut, 8. flexible sealing ring, 9. anti-corrosion layer.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of Flange joint regulating plunger stop valve as shown in Figure 1, there is valve body 1, valve body 1 is provided with the valve gap 2 coordinated with valve body 1, flexible sealing ring 8 is provided with between valve body 1 and plunger 4, the lumen centers position of valve body 1 is provided with plunger 3, plunger 3 is provided with valve rod 4, valve rod 4 is connected with handwheel 5, the appearance limit of valve body 1 is coated with anti-corrosion layer 9, bolt 6 is adopted to be connected between valve body 1 with valve gap 2, be connected by post nut 7 between plunger 3 with valve rod 4, valve body 1 adopts metal stainless steel to make.
It is concrete when handwheel 5 rotates, drive plunger 3 in the open and close function of the middle valve that pumped of valve body 1 by valve rod 4, interference fit is adopted between plunger 4 and flexible sealing ring 8, by adjusting bolt pretightening force, lateral force flexible sealing ring 8 being compressed produce and valve body 1 mesopore face plunger 4 cylindrical seal, thus ensure that the sealing of valve, stop internal leakage.Because flexible sealing ring 8 adopts rebound elasticity strong, the nontoxic sealing material that wear resistance is high is so sealing is reliable, durable in use.Thus improve the working life of valve.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
