According to above-mentioned a kind of Novel gate valve, wherein, the other end of fork is connected with running shaft, and running shaft extend out to the outside of described valve body.
According to above-mentioned a kind of Novel gate valve, wherein, linkage mechanism comprises swivel link and traction link, and swivel link and described traction link are connected to each other.
According to above-mentioned a kind of Novel gate valve, wherein, when circular baffle plate and latus rectum fit like a glove, the angle between swivel link and traction link is 90 °.
According to above-mentioned a kind of Novel gate valve, wherein, the other end of swivel link is connected with the running shaft of the outside of valve body.
According to above-mentioned a kind of Novel gate valve, wherein, the other end of traction link is connected with the driveshaft of described drive unit.
According to above-mentioned a kind of Novel gate valve, wherein, when circular baffle plate and latus rectum fit like a glove, the angle between traction link and driveshaft is 90 °.
According to above-mentioned a kind of Novel gate valve, wherein, valve body periphery is provided with housing.Wherein, described driveshaft can elongate or shorten under the effect of described drive unit, thus drives described Novel gate valve to open or close.
When push-pull valve is opened, drive unit drives driveshaft, traction link, swivel link and running shaft to rotate, and band motive sealing pendulum plate rotates, and valve body and latus rectum are departed from completely, and now, sealing pendulum plate is in free state, and required drive unit output torque is less.
When push-pull valve cuts out, drive unit drives driveshaft, traction link, swivel link and running shaft to rotate, and band motive sealing pendulum plate rotates, valve body and latus rectum are fitted like a glove, in this process, the reaction force of sealing pendulum suffered by plate increases, gradually until close completely.Required work moment is the resultant moment of drive unit output torque and driveshaft support force, in this process, the angle that traction link and swivel link are formed is close to 90 °, the output torque proportion of required drive unit constantly reduces, make the output torque change smooth fluctuations of drive unit, limit output torque is little, and the running shaft speed of rotation is little, close impact little, noise is low.
Beneficial effect
The beneficial effects of the utility model are:
(1) simple and compact for structure, reliable performance;
(2) sealing action adopts linkage mechanism to drive, and considerably reduces drive part output torque;
(3) external driving and bindiny mechanism, level of integration is high, install and easy to maintenance;
(4) external driving and bindiny mechanism's adjustable angle, can meet different installation requirements.
Accompanying drawing explanation
The structural representation of Fig. 1 when a kind of Novel gate valve is opened completely disclosed in the utility model;
Fig. 2 disclosed in the utility model a kind of Novel gate valve from transitional structure schematic diagram when being opened to closedown;
The structural representation of Fig. 3 disclosed in the utility model during a kind of Novel gate valve closedown.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
The structural representation of Fig. 1 when a kind of Novel gate valve is opened completely disclosed in the utility model, as shown in Figure 1, a kind of Novel gate valve, comprise valve body 01, sealing pendulum plate 02, linkage mechanism 03 and drive unit 04, valve body 01 top is provided with latus rectum 05, sealing pendulum plate 02 is arranged in valve body 01, the circular baffle plate 07 that sealing pendulum plate 02 comprises fork 06 and coincide with latus rectum 05, circular baffle plate 07 is connected to one end of fork 06, the other end of fork 06 is connected with running shaft 08, running shaft 08 extend out to the outside of valve body 01, linkage mechanism 03 is in the outside of valve body 01, linkage mechanism 03 one end is put plate 02 with sealing and is connected, the other end is connected with the driveshaft 09 of drive unit 04, linkage mechanism 03 comprises swivel link 10 and traction link 11 particularly, swivel link 10 and traction link 11 are connected to each other, the other end of swivel link 10 is connected with the running shaft 08 of the outside of valve body 01, the other end of traction link 11 is connected with the driveshaft 09 of 04 drive unit, when circular baffle plate 07 fits like a glove with latus rectum 05, angle between swivel link 10 and traction link 11 is 90 ° and angle between traction link 11 and driveshaft 09 is 90 °, valve body 01 periphery is provided with housing 12.
As shown in Figure 1, when Novel gate valve is opened, it is the longest that drive unit 04 drives driveshaft 09 to be stretched to, driveshaft 09 drives dynamic traction link 11 and swivel link 10 to rotate, swivel link 10 driven rotary axle 08 is rotated, thus band motive sealing pendulum plate 02 rotates, and makes circular baffle plate 07 and latus rectum 05 depart from completely.In this case, sealing pendulum plate 02 is free state, and required drive unit 04 output torque is little.
