Abstract
The utility model relates to a high-temperature resistant gas steel plate sluice valve. A valve body (1) of the high-temperature resistant gas steel plate sluice valve is provided with a double-sealing seat (12), a guide track (9) provided with an inclined plane, and a limit stop block (13); a valve plate (2) is provided with an elastic valve plate (11), a wedge-shaped limit pin (3) and a rolling wheel mechanism (10) which comprises a wheel shaft (15), a sealing shield ring (16), a rolling wheel (17) and a shield wheel (18); the valve body is also provided with cleaning holes (19) and sewage draining holes (20); a ventilating mechanism (14) which is ventilated with pressure gas is arranged between the two sealing seats. The high-temperature resistant gas steel plate sluice valve can be driven by liquid pressure, or by hand. With the advantages of light weight, and reliable sealing, the utility model is particularly suitable for the operating conditions of high temperature (< 750DEG. C) and frequent burning gas open and close.
Description
The utility model relates to a kind of gate valve, especially a kind of high temperature resistant, combustion gas steel plate gate valve.
The high temperature cut-off valve of present domestic use generally adopts the general wedge action valve of heat resisting cast iron or general cast iron.For guaranteeing sealing, flashboard must be closed on earth, because expand when high temperature and cooling in each position of valve parts, the contour projector difference, can produce the dead phenomenon of wedge of not opening, and sealing effect is poor, and fault is frequent, is difficult to adapt to the needs of frequent unlatching operating mode (as two sections stove producing gas methods).
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of applied widely, high temperature resistant, in light weight, open and close flexibly, reliable, the easy to operate combustion gas steel plate gate valve of sealing.
The utility model is realized the technological scheme of above-mentioned purpose: adopt the double-sealing stand structure of band elasticity valve plate, two valve plates and two sealing seats are promptly arranged; Under the compressing of wedge shape position limit pin, valve plate and sealing seat are fitted and are reached sealing; Roller, gear wheel are housed on valve plate, the Expanded graphite Sealing shield ring is housed in the roller; Rolling wheel guide rails one end is designed to the inclined-plane, and when valve plate arrived closed condition, roller rolled down from the inclined-plane, and valve plate is just fitted with sealing seat, and valve plate one is opened, and roller rolls on guide level, and valve plate promptly breaks away from sealing seat.
With sidepiece pollutant exhaust hole and cleanout are housed in the valve body bottom, the ventilating mechanism of the clean air that can be connected with certain pressure is housed in the middle of inside and outside sealing seat.
Owing to adopt the elasticity valve plate, rely on its resiliently deformable to guarantee sealing, so still can reach reliable sealing after the sealing pair generation thermal distortion during high temperature, the ventilating mechanism in the middle of two seals and the sealing seat can reduce the possibility of internal leakage, raising sealability.The setting of valve plate roller, valve body guide rail has reduced the frictional force between valve plate and valve body, and making stem shaft power is that tractive force reduces.The setting of gear wheel, can make valve plate in leaving the valve body of expansion gap about guiding, open and close steadily, flexibly.Valve plate only just contacts in closed position with sealing seat, has reduced the abrasion of valve plate and sealing seat, can satisfy the operating mode of frequent keying, improves valve working life.Valve is provided with cleaning system, can in time remove impurity such as dust stratification, tar.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the half sectional view of first mode of execution plan view of the utility model.
Fig. 2 is the sectional view of first mode of execution right elevation of the utility model.
Fig. 3 is the sectional view of first mode of execution roller mechanism of the utility model.
Fig. 4 is the structural representation of ventilating mechanism between first mode of execution sealing seat of the utility model.
Fig. 5 is the half sectional view of second mode of execution plan view of the utility model.
Fig. 6 is the sectional view of second mode of execution left view of the utility model.
Fig. 7 is the structural representation of second mode of execution doctor blade device of the utility model.
Fig. 1, shown in Figure 2 be a kind of structure of the present utility model, form by valve body 1, valve plate 2, wedge shape position limit pin 3, connecting pin 4, link 5, valve rod 6, connector 7, oil cylinder 8, guide rail 9, roller mechanism 10, elasticity valve plate 11, double-sealing seat 12, positive stop 13, ventilating mechanism 14 etc.
Roller mechanism shown in Figure 3 is made up of wheel shaft 15, Sealing shield ring 16, roller 17 and gear wheel 18 etc.
Sealing seat ventilating mechanism 14 shown in Figure 4 is made up of union body 21, nut 22, pipe 23 etc.
Oil cylinder 8 drives valve plate 2 and moves towards sealing seat 10, when near closed position, roller 16 rolls down from guide rail 13 inclined-planes, and the sealing surface of valve plate 2 contacts with interior sealing seat with external sealed seat, elasticity valve plate 11, and under the effect of wedge shape position limit pin 3, tightly fit, guaranteed that the sealing of the condition of high temperature is reliable.Open when valve one, roller rolls on guide rail 9 planes, and valve plate 2 breaks away from double-sealing seat 12, can reduce the wearing and tearing and the stem shaft power of valve plate and sealing seat.When valve plate was closed, ventilating mechanism 21 can lead to gas greater than valve working pressure as a kind of anti-leak safety installations, can make in crossing a small amount of medium of sealing surfaces can not cross the external sealed face, had improved sealability, also can remove the dust stratification between sealing seat.The valve body both sides are provided with clean-out hatch 19, can regularly blow, and clean the dust stratification on the track, prevent to block roller.The valve body bottom is for what tilt, and the pollutant exhaust hole 20 that is provided with on the bottom can be got rid of impurity such as tar.
Fig. 5, shown in Figure 6 be another kind of structure of the present utility model.Less for bore, open the not frequent valve of number of times, can manual opening-closing.In connector 7 one terminations screw rod 24 is arranged, bearing sleeve (nut) 26 is housed being equipped with on the valve body support on bearing support 25, the screw rod 24, handwheel 27 is housed on it, also be welded with connector guide rail 28 on the support.This kind structure, as long as screw rod 24, handwheel 27 are changed into oil cylinder 8, can the hydraulic driving valve.For the flat valve that crouches and install, also doctor blade device shown in Figure 7 29 can be installed on the valve plate 2, can strike off the laying dust on the guide rail, make valve opening and closing flexible.
