Description
Technical Field
The utility model relates to a steam blow-off valve especially relates to a high frequency high speed connection clamp splice for ultra-temperature high pressure steam blow-off valve.
Background
The blowdown application is one of the most important applications in a combined cycle power plant. These valves must vent the main steam of the waste heat boiler to the atmosphere bypassing the turbine at the very beginning of operation to ensure that the unit temperature does not rise too quickly. This is done because the process lines are hot before allowing steam to dump through the turbine bypass valve to the condenser, the conventional steam dump valve, the clamp block, and the stem are tightly fitted to the column to prevent rotation of the stem; when the action is slow, the friction sound of the connecting clamping block and the upright post is small, if the metal and metal friction needs to be started quickly, great noise can be generated, the upright post can be abraded after a long time, and the normal use of the valve is influenced.
SUMMERY OF THE UTILITY MODEL
The applicant carries out research and improvement aiming at the defects and provides a high-frequency high-speed connecting clamping block for an ultrahigh-temperature high-pressure steam emptying valve.
The utility model discloses the technical scheme who adopts as follows:
The utility model provides a high frequency high speed connects clamp splice for ultra-high temperature high pressure steam blow-down valve, includes the clamp splice body of two connections, set up the connecting hole of centre gripping valve rod between the clamp splice body, the guide arm is all connected to clamp splice body one side, set up the spread groove between the guide arm, centre gripping guide block in the spread groove, the guide block cover is established on the stand, the guide block adopts the polyether ether ketone material to make.
As a further improvement of the above technical solution:
The two clamping block bodies are detachably connected together through four bolts on the clamping block bodies and one bolt on the guide arm.
The stand that the guide block cover was established leans on the outside to set up the instruction sign, the complex the guide block leans on the outside to set up the groove of stepping down.
The indicating sign is connected to the upright post through an upper screw and a lower screw which penetrate through a waist-shaped hole formed in the indicating sign.
The utility model has the advantages as follows: the high-frequency high-speed connecting clamping block for the ultrahigh-temperature high-pressure steam emptying valve is characterized in that a guide block made of polyether-ether-ketone is arranged between the clamping block and the stand column, so that friction noise between metal and metal can not be caused when the valve is opened quickly, the stand column is not easy to wear, normal use of the valve is guaranteed, and the service life of the valve is prolonged.

Detailed Description
The following describes a specific embodiment of the present embodiment with reference to the drawings.
As shown in fig. 1 to 3, the high-frequency high-speed connecting clamping block for the ultra-high temperature and high pressure steam blow-down valve of the embodiment comprises two clamping block bodies 1 connected together, the guide arm 3 is connected to one side of each clamping block body 1, the two clamping block bodies 1 are detachably connected to one another through four bolts on the clamping block bodies 1 and one bolt on the guide arm 3, a connecting hole 11 for clamping the valve rod 2 is formed between the two clamping block bodies 1, a connecting groove 31 is formed between the two guide arms 3, a guide block 4 is clamped in the connecting groove 31, the guide block 4 is sleeved on the upright post 5, the outer side of the upright post 5 penetrates through a waist-shaped hole fixed connecting piece indicating sign 51 formed in the upper part and the lower part of the indicating sign 51 through a screw, a abdicating groove 41 is formed near the outer side of the matched.
When the high-frequency high-speed connecting clamping block for the ultrahigh-temperature high-pressure steam emptying valve is installed, firstly, the two clamping block bodies 1 are connected through bolts, bolts are not screwed, then the valve rod 2 and the guide block 4 are arranged in the connecting hole 11 and the connecting groove 31, the bolts are screwed, the valve rod 2 and the guide block 4 are clamped, the executing component can drive the valve rod 2 to move, the valve is opened and closed, the clamping block and the guide block 4 are driven to move along the upright post 5 when the valve rod 2 moves, the function of preventing the valve rod 2 from rotating is achieved, the guide block 4 is arranged between the upright post 5 and the clamping block, the upright post 5 and the clamping block are not in direct contact, friction noise between metal and metal cannot be caused, the upright post 5 is not easy to wear, the guide block 4 is made of polyether ether ketone materials, the wear resistance is good, the wear resistance is not easy to wear.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
