Abstract
The utility model discloses a floating valve plate open type board plug valve with efficiently avoiding sealing ring injury. The utility model is characterized in that the four corners of the frame of a valve plate (3) are respectively installed with a spring plate (5), and the middle of the spring plate (5) is installed internally with a sliding pin (6) connected with the valve plate (3). The two ends of the spring plate (5) are arranged in the chute (7). The utility model is convenient and simple to achieve the automatic reset of the valve plate sealing ring and avoid the injury of the sealing ring.
Description
Technical field
The utility model patent relates to a kind of unsteady valve plate open type push-pull valve (claiming intercepter valve (IV) again).It can realize on valve plate that seal ring dodges the action of sealing surface automatically, has guaranteed the intact of seal ring, thereby the reliability of valve is increased.
Background technique
At present, push-pull valve is widely used on the pipeline of industrial departments such as metallurgy, oil, chemical industry, coal gas.
Valve mainly is made up of left valve barrel, right valve barrel, bellows, valve plate, leading screw, nut, plate Denso, clamping Denso etc.
Because this kind valve its specific structure characteristics and seal form.This part at valve plate; it is unfavorable to the seal ring protection that problem goes out at original valve board structure; owing to be fixing valve plate; in valve opening; though right valve barrel has left sealing surface, the valve body sealing surface of left valve barrel and the seal ring of valve plate also are in a kind of contact condition, in the time of the motion valve plate; normal wearing and tearing and unexpected the scuffing all will take place in walking about and rocking of valve plate.Original structure such as Fig. 1.Wherein the structure among Fig. 1 is with the board-like transmission of standing valve, and this structure just exists above problem.
Summary of the invention
The purpose of this utility model is in order to overcome the problem that existing push-pull valve occurs when the motion valve plate, thus a kind of convenient easy unsteady valve plate open type push-pull valve of realizing that automatically reseting of valve plate seal ring avoids seal ring to scratch of elastic force that utilizes of design.
The technical solution of the utility model is:
A kind of unsteady valve plate open type push-pull valve, it is characterized in that four jiaos at valve plate 3 frameworks respectively are equipped with a flat spring 5, the center of flat spring 5 is coated with and makes its slidiing pin 6 that is connected with valve plate 3, and the two ends of flat spring 5 are arranged in chute 7, and chute 7 is positioned on the valve plate 3.
Described flat spring 5 is bow font structure.
Shown in Figure 2, at four angles of the quadra of valve plate 3, flat spring 5 is installed, the shape of flat spring 5 is as the bow font, the middle slidiing pin 6 that passes through is connected with valve plate 3, the two ends of flat spring 5 are placed in the chute 7, valve when closing, right valve barrel crush seal circle right side, flat spring 5 stress deformations, sliding in chute 7 in two ends, promotes valve plate 3 to the left valve barrel motion, finally airtight.During valve opening; right valve barrel leaves the seal ring of valve plate 3 under the synchronous drive of screw thread pair of nut anyway, and the seal ring in left side, under the effect that flat spring 5 resets; also leave the left valve barrel sealing surface of valve, thereby effectively protected the integrity of valve plate seal ring.
The beneficial effects of the utility model are, the convenient protective function of realizing the push-pull valve seal ring can be arranged, and are simple in structure, good practical effect.
Description of drawings
Fig. 1 is original valve valve board structure schematic representation.
Fig. 2 is that original valve sealing structure shows.
Fig. 3 is to use spring floating valve mechanism schematic representation.
Fig. 4 is to use the opening state of spring floating structure.
Among the figure
The 1st, right valve barrel, the 2nd, seal ring, the 3rd, valve plate, the 4th, left valve barrel, the 5th, flat spring, the 6th, slidiing pin, the 7th, chute.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 3.
In Fig. 3, four jiaos in valve plate 3 frameworks arc flat spring 5 is installed, flat spring 5 machining shapes are as the bow font, and the center sky of flat spring 5 is worn slidiing pin 6, is used for being connected with valve plate 3.The two ends of flat spring 5 are placed in the chute 7.By the connection of four direction, make valve plate 3 fixing.
Claims (2)
1. unsteady valve plate open type push-pull valve, it is characterized in that four jiaos at valve plate (3) framework respectively are equipped with a flat spring (5), the center of flat spring (5) is coated with the slidiing pin (6) that it is connected with valve plate (3), the two ends of flat spring (5) are arranged in chute (7), and chute (7) is positioned on the valve plate (3).
