Abstract
The utility model relates to a novel adjusting butterfly valve which comprises a valve body, a valve plate and a sealing ring body formed by sintering. An installation hole I is formed in the upper end of the sealing ring body. An installation hole II is formed in the lower end of the sealing ring body. Embedded grooves are formed in the two sides of the installation hole II. The whole bottom end of the sealing ring body is evenly coated with a plastic layer. A plurality of through holes are formed in the sealing ring body. The sealing ring body is a Y-type stainless steel sealing ring. According to the novel adjusting butterfly valve, due to the fact that the bottom end of the sealing ring body is coated with the plastic layer, the sealing effect of the novel adjusting butterfly valve can be improved; meanwhile, due to the fact that the through holes are formed in the sealing ring, stress concentration is prevented from being caused by excessively-large pressure acting on the end of the sealing ring in the using process.
Description
Technical field
The utility model relates to valve class field, relates in particular to a kind of novel regulating butterfly valve.
Background technique
Butterfly valve is again Flap valve, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.Its structure is mainly made up of valve body, valve rod, dish plate and seal ring, and valve body is cylindrical, and axial length is short, built-in dish plate.Its working principle is: dish plate is driven by valve rod, if turn over 90 °, opens and closes just can complete once.Change the deflection angle of dish plate, get final product the flow of control media.Its material decides according to purposes and medium, conventional butterfly valve has two kinds of wafer type butterfly valve and flange-type butterfly valves, wafer type butterfly valve is with stud bolt, valve to be connected between two piping flanges, flange-type butterfly valve be on valve with flange, two end flange on valve are connected on piping flange with bolt.
The main Sealing of butterfly valve is seal ring, and the seal ring sealing effect of prior art is poor, in use, easily causes the leakage of liquid,, bears in the process of pressure at seal ring meanwhile, can occur that stress is concentrated by seal ring, especially for metal o-ring.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of novel regulating butterfly valve is provided.
The utility model is to be achieved through the following technical solutions:
A kind of novel regulating butterfly valve, comprise the seal ring body that valve body, valve plate, sintering form, described seal ring body upper end has mounting hole I, the lower end of described seal ring body has mounting hole II, both sides at mounting hole II are provided with caulking groove, on the whole bottom of described seal ring body, be evenly coated with plastic layer, on seal ring body, have some through holes.
As optimal technical scheme of the present utility model, described seal ring body is Y type stainless steel seal ring.
As optimal technical scheme of the present utility model, described plastic layer is fluoroplastic, improves its wear-resisting and sealability.
As optimal technical scheme of the present utility model, the axis of described mounting hole I and mounting hole II is on same straight line., ensure can realize centering while installation.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being coated with plastic layer in the bottom of seal ring body, can improve its sealing effect, on seal ring, have through hole simultaneously, in use, prevent because the excessive stress that causes of pressure that acts on seal ring upper end portion is concentrated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The novel regulating butterfly valve of described one, comprise the seal ring body 1 that valve body, valve plate, sintering form, described seal ring body 1 upper end has mounting hole I2, the lower end of described seal ring body 1 has mounting hole II3, be provided with caulking groove 4 in the both sides of mounting hole II3, on the whole bottom of described seal ring body 1, be evenly coated with plastic layer 5, on seal ring body 1, have some through holes 6.
Described seal ring body 1 is Y type stainless steel seal ring, and described plastic layer 5 is fluoroplastic, and the axis of described mounting hole I2 and mounting hole II3 is on same straight line.
In sum, the utility model, by being coated with plastic layer in the bottom of seal ring body, can improve its sealing effect, has through hole on seal ring simultaneously, in use, prevents because the excessive stress that causes of pressure that acts on seal ring upper end portion is concentrated.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
