Abstract
The utility model relates to a baiting valve preventing blocking by heating, which comprises a valve seat, a valve body, a gland, a screw rod and a spool. The valve seat, the valve body, the gland andthe screw rod are all provided with axial holes and the spool penetrates the whole baiting valve; the upper end of the valve body is provided with the valve seat and is arranged on a retort; the bulbof the upper end of the spool matches the valve seat and the bulb has a diameter larger than the inner diameter of a valve seat hole; the lower end of the valve body is tightly connected with the upper end of the gland and the lower part of a gland hole on the gland is provided with inner threads which match the screw rod; the screw rod is sleeved at the lower part of the spool and is fixed; thebaiting valve is characterized in that: the valve body is provided with a double-layer structure with a cavity; by leading in hot fluid to the cavity, the residual feed liquid in the valve body keepsin liquid state and does not block the baiting valve due to crystallization, thus ensuring smooth production.
Description
Technical field
The utility model belongs to mechanical equipment technical field, particularly relates to a kind of heating anti-plugging discharging valve that is applied in the Chemical Manufacture.
Background technique
In fields such as chemical industry, food, pharmacy, metallurgy, the various tank bodies of depositing feed liquid all are provided with the discharging valve that is used to discharge feed liquid, behind the existing discharging valve blowing, and residual material crystallization at normal temperatures in the valve body, putty when causing next blowing brings a lot of inconvenience to production operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rational in infrastructure, heating anti-plugging discharging valve that can guarantee the efficient operation of production safety is provided.
The purpose of this utility model realizes that by following technological scheme described heating anti-plugging discharging valve comprises valve seat, valve body, gland, screw mandrel and spool, all offers axial hole on described valve seat, valve body, gland, the screw mandrel, and spool runs through whole discharging valve; Valve seat is installed in the valve body upper end, and is installed on the retort; Match with valve seat in bulb, spool upper end, described bulb diameter is greater than the valve seat orifice internal diameter; Valve body lower end and gland upper end are fastenedly connected, and the bottom, gland hole on the described gland is provided with internal thread, and internal thread matches with screw mandrel; Described screw mandrel is enclosed within spool bottom and fixing; It is characterized in that: described valve body is the double layer construction that is provided with cavity, offers heating gate and cooling vent on the outer wall of valve body.
Described spool is provided with pin-and-hole, and pin is installed in the pin-and-hole, and described pin cooperates spacing with radiation fins lower end inner edge.
Between described valve body upper end and the valve seat tetrafluoro asbestos packing is housed; Described screw mandrel is provided with handwheel.
The utility model compared with prior art is made as the double layer construction that has cavity with valve body, by import hot fluid in cavity, makes that residual feed liquid keeps liquid in the valve body, can crystallization and stop up discharging valve, guarantee the smoothness of producing.

Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described heating anti-plugging discharging valve comprises valve seat 11, valve body 8, gland 4, screw mandrel 3 and spool 9, all offers axial hole on described valve seat 11, valve body 9, gland 4, the screw mandrel 3, and spool 9 runs through whole discharging valve; Valve seat 11 is installed in valve body 8 upper ends, and is installed on the retort, between valve body 8 upper ends and the valve seat 11 tetrafluoro asbestos packing 10 is housed, and improves sealability; Described valve body 8 offers heating gate 18 and cooling vent 19 for being provided with the double layer construction of cavity 7 on the outer wall 7 of described valve body 8; Match with valve seat 11 in bulb 12, spool 9 upper end, the opening and closing of control discharging valve, and described bulb 12 diameters are greater than valve seat orifice 13 internal diameters; Be fastenedly connected by screw 5 between valve body 8 lower ends and gland 4 upper ends, 16 bottoms, gland hole on the described gland 4 are provided with internal thread, and internal thread and screw mandrel 3 cooperatively interact; Described screw mandrel 3 is enclosed within spool 9 bottoms and fixing by nut 1, and screw mandrel 3 is provided with handwheel 2, rotates with convenient.
Described spool 9 is provided with pin-and-hole 17, and pin is installed in the pin-and-hole 17, and described pin cooperates spacing with radiation fins 15 lower end inner edges, the stroke of control spool 9.
In the practical application, when needs are opened discharging valve, turn handwheel 2, screw mandrel 3 is by the inside precession of internal thread on the gland 4, promote spool 9 and inwardly move, bulb, spool 9 upper end 12 breaks away from valve seat 11, and discharging valve is an open mode, specifically as shown in Figure 2, the feed liquid in the retort flows out from valve port 14 via valve seat orifice 13; When needs are closed discharging valve, reverse turn handwheel 2, spool 9 outwards moves, and fits closely with valve seat 11 and seal in bulb, spool 9 upper end 12, leaves the feed liquid that does not flow out fully this moment in the valve body 8, hot fluid flows in the cavity 7 by the heating gate on the valve body 8 18, residual feed liquid in the heating valve body 8, the hot fluid after the heating flows out from cooling vent 19, and hot fluid constantly circulates, feed liquid in the valve body 8 can not stopped up in crystallization, had influence on next blowing.
