Description of the invention (3) Temple cage h Restricted by the present invention The evacuation valve of the CVD device is: (CVD: C hemica 1 V a f > 〇 "D e ρ 〇si 1: 1 ο η chemical vapor accretion) It has been used in the past. The valve body of the vacuum exhaust system installed in the CVD device has a gas inlet 1 on the right side and a gas on the lower side as shown in Figure 6 The valve box 3 flowing out of U 2 is sealed with a corrugated hose 6 on the upper side of the action connection part of the valve body 5 which is opened and closed by the actuator 4. At the seal liner connected to the valve seat 7 of the valve body 5 (ga S ket ) 8 Pseudo gas rubber is used. However, if the exhaust temperature is below U 〇 ° C, the product will adhere to the surface of the valve seat 7 or the sealing lining S and the corrugated hose 6, so when the valve is closed, The gas will leak. Therefore, Nai heats the valve, but because the sealing lining 8 uses gas rubber, the heating limit of the valve body is about 1 50 t ^ However, the rubber heater 9 installed outside the valve box body 3 Heating, even if the outside is 1 50 t, the inside is only about 30 t, if the inside of the valve is vacuum, the temperature is lower. Central Standard Hua Ma's uncle Gong Xiao f cooperation: ft Ingo I-----»I 1---: -I-11 Shi-I (Qi Xian M- ^ film and attention«, Xiang Bian 4 艿 本In this way, the rubber heater 9 is heated from the outside, because the temperature difference between the valve box 3 and the inside is large, and the valve body 5 or the corrugated hose 6 cannot be heated to U (above TC, _, so the valve body 5 or the corrugated hose 6 has to be left with the product of the chopsticks. Therefore, the valve body must be cleaned frequently, the life of the corrugated tube is shortened, and the durability of the valve body is also lacking. Β 明 要 解 :> The present invention provides a vacuum exhaust valve of a CVD device that can perform stable heating in the valve body without the product being attached to the valve body or the corrugated hose, etc. This paper standard is applicable to the Chinese National Standard (CMS) A4 Specifications (210X297mm) ό A7 B7 Printed by the Cooperative Society of the Central Ministry of Economic Affairs of the Ministry of Economy V.

Description of the invention (5) The heater, the lower end of which is fixed on the upper side of the valve body. The upper end of the body is fixed to the upper end, and the wire connected to the outside of the valve box is shortened when the valve is opened and closed, except for the lifting of the valve body, and the elastic member is displaced. Therefore, The valve body or the corrugated hose will be generally average and stable, especially when the sheath thermocouple is installed inside the sheath heater, the heating temperature of the rug heater can be set in the required range to obtain Stable temperature control target. Therefore, the product is not easy to be attached to the valve body or the corrugated hose. It can greatly reduce the cleaning frequency inside the valve body, extend the life of the corrugated kinkya, and improve the durability of the valve body. In addition, because the sheath heater pseudo-molds the metal tube into a coil spring shape that can be elastically stretched, and the electric heating wire is inserted through it, the electric heating wire is not drawn into a duck when the valve body is opened and closed External force such as bending. It can be freely displaced in the spiral elastic metal tube, so there will be no friction or wire breakage. An example of a vacuum exhaust valve of a CVD apparatus according to the present invention will be described in accordance with the drawings: As shown in FIG. 1, a valve box having a gas inlet 1 on one side and a gas outlet 2 on the bottom Inside the body 3, the actuator (actuat 〇 ") is sealed with a soft pattern 6 on the top, which is the case in this example; the valve body 5 according to the opening and closing action of the cylinder 4 is used as a connecting part, and the valve seat 7 is connected to the gear The use of the valve body 5 is a vacuum exhaust valve with a fluorine rubber pendulum as the sealing liner 8, and the elastic heater can be shrunk for a long time.

Description of the invention (6) The heater U Ao is formed from a gold drive tube into an elastically retractable coil spring, and if the electric heating wire is inserted inside, the lower end of the heater is pseudo vortex inward It is wound around, and pushed by a hun-shaped plate 5 and locked with bolts 16 on the holder 10 above the valve body 5, the upper end of which is fixed on the top surface of the valve box 3 and connected to the valve box 3 Outside the lead 1 7. Moreover, as other yellow + examples, there are; on the inner peripheral side of the sheath heater 14 as shown in FIG. 3, the sheath thermocouple is concentrically arranged at the same height and the same coil number, the lower end It is fixed above the valve body 5, and the upper end is fixed on the top surface inside the valve box 3, and is connected to the wire 19 outside the valve box 3. The vacuum exhaust valve shown in FIG. 1 of the above-structured embodiment operates when the air is supplied to the upper chamber of the cylinder 4 and pushes the push rod 11 connected to the racing rod 9, and the valve body 5 extends into a corrugated hose 6 and descend, as shown in FIG. 2, the sealing lining 3 under the valve body 5 is pushed to the valve seat to be sealed, and it becomes a closed state. 1. When the air in the upper chamber of the cylinder 4 is supplied with oil and the air is supplied in the T chamber to reverse the action, the push rod U connected to the piston 9 is raised, the lug body 5 is shortened and the corrugated hose 6 is different, as shown in the figure As shown in FIG. 1, the sealing lining 3 of the valve body 5 is separated from the valve seat 7 to form a valve-open state. The Ministry of Economy, Central Standards Bureau, Employee Consumption Cooperation 'company is in arrears. , All inside the corrugated soft Jin 6, the lower end is fixed on the valve body 5 above the holding member 10, and the upper end is fixed on the top of the valve box 3, with an integral up and down flexible heating jacket heating 1 4, therefore, the corrugated hose 6 can heat the radiant heat of the sheath heater U stably and continuously to 1800 0 ~ 2 0 0 C in all goodness, the valve body 5 is pseudo-slave from the sheath The lower end of the heater 1 4 is heated by the heat conduction of the holder 10: The paper standard is in accordance with the Chinese National Standard (CNS) Λ4 present grid (210Χ297mm) 6 A7 B7 Printed by the cooperative. 5.
