Abstract
The utility model relates to a floating type ball valve with high temperature whose inlet side is provided with springs. The utility model comprises an end cover, springs, a valve body, a ball, a ball seat, sealing rings, etc. The springs which are arranged on the inlet side of the valve provide the original pressure force for the valve, making the assembly of the valve very easy. The high temperature can not influence the pressure force. The utility model is the perfect production in the matching use with the automatic ignition system of a boiler in a thermal power plant.
Description
The utility model relates to the high temperature Float ball valve that a kind of suction side has spring.It is made up of end cap, valve body, spheroid (through hole), ball seat, valve rod, seal arrangement and spring.
According to the actual conditions in China power station, require to reach 350 ℃ with the heatproof degree of the matching used electric ball valve of heat power plant boiler automatic ignition system, and only 250 ℃ of electric ball valve heatproofs that U.S. Wcrcester company produces.For solving high temperature, adopt bigger, the homemade Expanded graphite of sealing to make sealing material, but its force characteristic is hard, adding upper ball base, to lay the groove size of Expanded graphite seal ring big along the axial accumulated error of valve body, make the extremely difficult control of impacting force just, be prone to spheroid locking or packing less result, also be difficult to guarantee the moment requirement of electrical header.Homemade ball valve is with soft ball seat and spacer adjustment, and high-temperature ball valve can't be adjusted the tight power of initial pressure with soft ball seat and spacer, wastes time and energy like this, is subject to the influence that elevated temperature heat expands again.
The purpose of this utility model is to avoid the deficiency in the above-mentioned technology, and provides a kind of suction side to have spring, utilizes its elastic force to provide the high temperature Float ball valve of required initial impacting force between oral-lateral spheroid and ball seat, ball seat and end cap.
The purpose of this utility model can reach by following measure:
The high temperature Float ball valve that provides, form by end cap, spheroid, valve body, ball seat and valve rod etc., in a side end cap, spring is housed, and pass through bolt, fixed by nut on valve body, spheroid and valve rod are packed in the valve body simultaneously, by the ball seat supporting, an end of spring acts on the ball seat, between opposite side end cap and the ball seat seal ring is housed.
The purpose of this utility model can also reach by following measure:
Adopt homemade Expanded graphite seal ring between outlet side ball seat and the end cap, bear the first impacting force that the suction side spring provides, reach effect high temperature resistant and sealing.
The utility model compared with prior art has following advantage:
1. assemble very conveniently, simple, time saving and energy saving, need not to adjust repeatedly.
2. its impacting force is not subjected to the influence of high temperature.
3. guarantee sealing and torque demand.
Be described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the structure sectional view of high temperature Float ball valve.
Among the figure: 1--end cap 2--spring 3--spheroid
4--valve body 5--ball seat 6--seal ring
The 7--valve rod
High temperature Float ball valve provided by the utility model is made up of end cap (1), spring (2), spheroid (3), valve body (4), ball seat (5), seal ring (6) and valve rod (7).Suction side end cap (1) is as spring seat, spring (2) is packed in its hole, end cap (1) passes through bolt, fixed by nut on valve body (4), the other end of spring (2) acts on the ball seat (5), thereby realizes that the first impacting force between outlet side spheroid (3) and ball seat (5), ball seat (5) and the end cap (1) is provided by spring (2).Spheroid (3) is packed into simultaneously with valve rod (7) in the valve body (4), support by ball seat (5), be equipped with between outlet side end cap (1) and the ball seat (5) that to select homemade Expanded graphite for use be that the seal ring (6) of material bears the first impacting force that suction side spring (1) is provided, reach effect high temperature resistant and sealing.
Claims (3)
1, a kind of high temperature Float ball valve, have end cap (1), spheroid (3), valve body (4), ball seat (5) and valve rod (7), it is characterized in that: spring (2) is housed in a side end cap (1), end cap (1) passes through bolt, fixed by nut on valve body (4), spheroid (3) is packed into simultaneously with valve rod (7) in the valve body (4), by ball seat (5) supporting, an end of spring acts on the ball seat (5); Between opposite side end cap (1) and the ball seat (5) seal ring (6) is housed.
2, high temperature Float ball valve according to claim 1 is characterized in that seal ring (6) selects homemade Expanded graphite for use.
3, high temperature Float ball valve according to claim 1, a side that it is characterized in that being equipped with spring (2) is a suction side.
