Has the advantages that: the utility model discloses a design in ka tai and the card groove for being connected between valve rod and the valve body is more firm, has effectively avoided popping out of valve rod when the valve body uses under the high temperature high pressure condition, has reduced the potential safety hazard that the ball valve used, reduces the cost of maintenance of ball valve, has improved the life of ball valve.
Description
Technical Field
The utility model relates to a ball valve technical field, concretely relates to explosion-proof valve body of ball valve.
Background
The ball valve is a valve whose opening and closing piece is driven by valve rod and can make rotary motion around the axis of ball valve, and can be used for regulating and controlling fluid, in which between its V-shaped core and metal valve seat of bead weld hard alloy a strong shearing force is existed, so that it is specially applicable to the medium containing fibre and small solid granules, etc.
When the existing ball valve is used in a high-temperature and high-pressure environment, the pressure inside the pipeline and the valve body is high, and the valve rod of the ball valve is easily pushed out from the valve body under the condition of high pressure of the valve body, so that the ball valve cannot keep a normal working state, the potential safety hazard and the maintenance cost of the use of the ball valve are increased, the service life of the ball valve is reduced, and the existing problem is solved by urgently needing an explosion-proof valve body of the ball valve.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome the defects of the prior art, the explosion-proof valve body of the ball valve is provided, and the problems that when the existing ball valve is used in a high-temperature and high-pressure environment, the pressure in a pipeline and the valve body is high, a valve rod of the ball valve is easily pushed out from the valve body under the condition of high pressure of the valve body, the ball valve cannot keep a normal working state, the potential safety hazard and the maintenance cost of the use of the ball valve are increased, and the service life of the ball valve is shortened are solved.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides an explosion-proof valve body of ball valve, including valve body, valve rod and ka tai, the valve body adopts the integral type structure, valve body upper end middle part is rotated and is connected with the valve rod, the shaping of valve rod bottom has the dop, be close to on the peripheral lateral wall of valve body dop department shaping has the ka tai, be close to on the valve body ka tai department shaping has the card groove, the valve rod passes through the ka tai with the card groove links to each other.
By adopting the technical scheme, through the design of the clamping table and the clamping groove, the valve rod is more firmly connected with the valve body, the valve rod is effectively prevented from popping up when the valve body is used under the conditions of high temperature and high pressure, the potential safety hazard of the use of the ball valve is reduced, the maintenance cost of the ball valve is reduced, and the service life of the ball valve is prolonged.
Furthermore, a valve ball is inserted into the bottom end of the valve rod, and an installation groove is formed in the middle of the upper end of the valve ball and is opposite to the clamping head.
By adopting the technical scheme, the reliable installation and fixation of the valve rod and the valve core can be realized through the clamping head and the installation groove.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
when using under the highly compressed environment of high temperature for solving current ball valve, pipeline and valve body internal pressure are great, and the ball valve rod is outwards released from the valve body easily under the great condition of valve body pressure, makes the ball valve can't keep normal operating condition, has increased potential safety hazard and the cost of maintenance that the ball valve used, has reduced the life's of ball valve problem, the utility model discloses a design of ka tai and card solid groove for being connected between valve rod and the valve body is more firm, has effectively avoided popping out of valve rod when the valve body uses under the high temperature high pressure condition, has reduced the potential safety hazard that the ball valve used, reduces the cost of maintenance of ball valve, has improved the life of ball valve.
