The utility model discloses the outer leakage of valve under temperature is eliminated simultaneously in the transport and the regulation of the effectual assurance high viscosity medium of ability.
Description
Technical field
The utility model relates to valve body, specifically a kind of ball valve used in high viscosity medium.
Background technique
When medium becomes solid, glue or stickum at normal temperatures, and becoming liquid when being incubated or the convenient conveying of gaseous state situation, usually adopting thermal insulation clamp sleeving valve.And the valve body external leakage expanding with heat and contract with cold brought that integral heat preservation jacketed valve produces under preventing the situation that affects by temperature, what ensure in medium transport process is reliable and stable.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of ball valve used in high viscosity medium, effectively can ensure conveying and the adjustment of high viscosity medium, eliminates the external leakage of valve under temperature impact simultaneously.
According to the technical solution of the utility model: a kind of ball valve used in high viscosity medium, it is characterized in that: comprise valve body, the built-in valve seat of valve body, valve seat is fixed by gland, and valve seat is supported with valve ball, valve ball is fixedly connected with valve shaft, valve shaft stretches out from valve body, and valve body stretches out side corresponding to valve shaft and is fixed with support, valve shaft upper end is connected with coupling shaft, support is fixed with actuator, and coupling shaft upper end is connected with the clutch end of actuator; Valve body corresponds to diameter of axle surface, valve shaft upper end and be provided with stuffing box, in stuffing box, be provided with Packing seat.
As further improvement of the utility model, between described gland and valve body, be provided with seal ring.
As further improvement of the utility model, described actuator is provided with detection control part.
As further improvement of the utility model, valve body corresponds to valve ball place and be provided with medium channel.
Technique effect of the present utility model is: integral heat preservation ball valve chuck adopts through impact briquetting, and ensure enough soak zones between valve body, there is excellent insulation cold insulation characteristic, and the latus rectum of valve is consistent with caliber, effectively can reduces pipeline medium heat loss again simultaneously.Be widely used, be mainly used in the sorts of systems such as oil, chemical industry, metallurgy, pharmacy, food, with to carry under normal temperature can crystallization, the high viscosity medium that solidifies.Owing to adopting monolithic construction, thus Thermal insulating ball valve is less than general ball valve volume, and weight is lighter, and without leaking outside, favorable sealing property.Chuck adopts material wall thickness to consider the temperature and pressure impact of heat medium, more firmly withstand voltage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1, comprise valve body 1, valve seat 2, valve ball 3, valve shaft 4, stuffing box 5, support 6, coupling shaft 7, actuator 8, control unit 9, seal ring 10, gland 11 etc.
As shown in Figure 1, the utility model is a kind of ball valve used in high viscosity medium, comprises valve body 1, the built-in valve seat 2 of valve body 1, valve seat 2 is fixed by gland 11, valve seat 2 is supported with valve ball 3, valve ball 3 is fixedly connected with valve shaft 4, and valve shaft 4 stretches out from valve body 1, valve body 1 stretches out side corresponding to valve shaft 4 and is fixed with support 6, valve shaft 4 upper end and coupling shaft 7) be connected, be fixed with actuator 8 on the frame 6, coupling shaft 7 upper end is connected with the clutch end of actuator 8; Valve body 1 corresponds to diameter of axle surface, valve shaft 4 upper end and be provided with stuffing box 5, in stuffing box 5, be provided with Packing seat.
Be provided with seal ring 10 between gland 11 and valve body 1, actuator 8 be provided with detection control part 9, valve body 1 corresponds to valve ball 3 place and be provided with medium channel.
Actuator 8 in the utility model is pushing devices of ball valve, and it produces the power of corresponding implementation capacity as valve body action according to signal magnitude, and the actuator of pneumatic control valve is connected with pressure gauge.
Working procedure of the present utility model is as follows: after heat medium reaches set point of temperature, control unit 9 produces by control room signal air inlet/electric control actuator 8 and rotates, drive coupling shaft 7, valve shaft 4 make valve ball 3 synchronous axial system under the support of valve seat 2, and the thermal medium in valve body 1 performs to close when rotating and opens and regulating action by the hole on spheroid.
In the process of implementation, the medium in ball valve, first by the dielectric heating in chuck, because valve body 1 is integrated, can not cause generation external leakage so expand with heat and contract with cold; Because whole for valve body folder can be entered by chuck, thus can not produce be heated uneven, prevention medium valve shaft 4 filler place condensation and valve body 1 import and export condense, guarantee the stability of valve in use medium transport, adjustment; Because adopting monolithic construction, thus Thermal insulating ball valve is less than general ball valve volume, and weight is lighter.
The utility model adopts integral valve body, less than general ball valve volume, and weight is lighter, and without leaking outside, favorable sealing property.
Insulation jacket through impact briquetting, and ensures enough soak zones between valve body, have good insulation cold insulation characteristic, effectively can reduce pipeline medium heat loss again simultaneously.
Chuck adopts material wall thickness to consider the temperature and pressure impact of heat medium.More firmly withstand voltage.Chuck welds with outside valve body, and the maximum pressure allowing steam or cold water is 2MPa.
