Abstract
The utility model provides a feed screw nut clamping spectacles valve, which comprises a valve body, a valve plate, and a feed screw nut clamping mechanism, wherein the valve plate is arranged inside the valve body, the valve body is provided with six feed screw nut clamping mechanism, the valve plate is provided with an internal layer sealing ring and an external layer sealing ring, and the internal layer sealing ring is made of silicon rubber while the external layer sealing ring is made of graphite packing. The utility model has the advantages that employment of six-point clamping strengthens high pressure resistance of valves, the double sealing rings can improve high temperature resistance of the valves, compensate for errors of processing and assembling of parts, and increase sealing property of the valves.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of glasses valve.
Background technique
The bikini glasses valve that generally uses on the metallurgy industry gas pipe line by the clamping to three equal branches of valve, reaches the purpose of valve seal at present.Under the fitness for purpose condition, this structure can reach the purpose of sealing, but under the high pressure-temperature condition, the bikini glasses valve can not reach good sealing effect, causes the leakage of valve, has a strong impact on environment and personnel's safety.
Summary of the invention
Leak at high pressure-temperature condition lower valve in order to overcome existing bikini glasses valve, have a strong impact on the deficiency of environment and personnel's safety, the utility model provides a kind of feed screw nut to clamp glasses valve.
The technological scheme that its technical problem that solves the utility model adopts is that a kind of feed screw nut clamps glasses valve, comprise valve body, valve plate, feed screw nut's fastening device, valve plate is installed in the valve body, feed screw nut's fastening device is housed on the valve body, feed screw nut's fastening device quantity is six, internal layer seal ring and outer seal ring are housed on the valve plate, and the internal layer sealing ring material is a silicone rubber, and outer sealing ring material is the graphite packing.
The beneficial effects of the utility model are to adopt 6 clampings, strengthen the high voltage performance of valve, the employing flexible graphite stuffing adds the double sealing circle of silicone rubber, strengthens the resistance to high temperature of valve, processing and assembly error that in addition can also the offset zero part improve the sealability of valve.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a tectonic maps;
Fig. 2 is the left view of Fig. 1;
Among the figure: 1. valve body; 2. feed screw nut's fastening device; 3. valve plate; 4. internal layer seal ring; 5. outer seal ring.
Embodiment
As shown in Figure 1 and Figure 2, a kind of feed screw nut clamps glasses valve, comprise valve body 1, valve plate 3, feed screw nut's fastening device 2, valve plate 3 is installed in the valve body 1, feed screw nut's fastening device 3 is housed on the valve body 1, feed screw nut's fastening device 3 quantity are six, and internal layer seal ring 4 and outer seal ring 5 are housed on the valve plate 3.Internal layer seal ring 4 materials are silicone rubber, and outer seal ring 5 materials are the graphite packing.Owing to adopt 6 clampings, significantly strengthen the high voltage performance of valve, employing silicone rubber adds the double sealing circle of graphite packing, has strengthened the resistance to high temperature of valve, makes valve reliable at the high pressure-temperature lower seal.
