The product of the utility model is simple in structure rationally, case lower extreme and the perfect cooperation of disk seat ability are realized better sealedly between ability in vogue and the disk seat under the case, it is streamlined that first passageway and second channel all are S, can make the pressure drop loss less, and the flow is big, and the adjustable range is wide, and the flow characteristic precision is high, the action is reliable, the little body of shape is light.
Description
Technical field
The utility model relates to valve body, specifically a kind of sealed-regulating valve base device.
Background technique
At present, in prior art, conventional pneumatic modulating valve generally should not be adopted to carry out the adjustment of the medium to hypertoxic, valuable, volatile, easy infiltration, because although conventional pneumatic modulating valve is also combined by many springs diaphragm actuator and single-seat adjusting valve, but because its valve seat adopts hard sealing, have certain leakage rate, and filler place also likely leaks, and No leakage instruction, although so though this kind of structure has reliable in action, the feature such as is rapidly opened in featuring rigid cutting-off, pass; But be not still suitable for without media such as granular, pure gas, liquid, steam.It is that valve body structure design is unreasonable that existing modulating valve also exists a larger problem, causes media flow to be a greater impact.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of sealed-regulating valve base device, and this regulating valve seat apparatus structure is simple, can realize sealing effect preferably in the course of the work, also have good leading role simultaneously to the flowing of medium.
According to the technical solution of the utility model: a kind of sealed-regulating valve base device, it is characterized in that: comprise valve body, valve seat is tightened against in valve body, valve seat is provided with spool, valve body upper step place's fixed connection and sealing seat, the top core body of spool stretches in sealing seat, and spool upper end hole is fixedly connected with connecting rod, connecting rod center is provided with blind hole, is provided with valve rod in blind hole; Sealing seat upper step is connected valve gap.
As further improvement of the utility model, described valve gap is connected by bolt, fastening nuts with between valve body.
As further improvement of the utility model, described sealing seat offers inclined hole, valve body offers first passage, second channel, the mounting groove of described inclined hole upper end communication seals seat gyration center, inclined hole lower end is communicated with first passage.
As further improvement of the utility model, described first passage, both second channels are all curved, and first passage is placed in above second channel.
As further improvement of the utility model, described sealing seat and valve gap and be respectively equipped with gasket seal between sealing seat and valve body.
Technique effect of the present utility model is: the utility model product structure advantages of simple, spool lower end and the perfect cooperation of valve seat energy, realizes better sealing when spool is descending between energy and valve seat; First passage and second channel are all streamlined in S, and droop loss can be made less, and flow is large, and adjustable extent is wide, and Flow characteristics precision is high, reliable in action, shape corpusculum are light.
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, first passage 1-1, second channel 1-2, valve seat 2, spool 3, valve rod 4, sealing seat 5, inclined hole 5-1, connecting rod 6, valve gap 7, bolt 8, nut 9 etc.
As shown in Figure 1, the utility model is a kind of sealed-regulating valve base device, comprise valve body 1, valve seat 2 is tightened against in valve body 1, valve seat 2 is provided with spool 3, valve body 1 upper step place's fixed connection and sealing seat 5, the top core body of spool 3 stretches in sealing seat 5, spool 3 upper end hole is fixedly connected with connecting rod 6, and connecting rod 6 center is provided with blind hole, is provided with valve rod 4 in blind hole; Sealing seat 5 upper step is connected valve gap 7.
Be fastenedly connected by bolt 8, nut 9 between valve gap 7 and valve body 1.
Sealing seat 5 offers inclined hole 5-1, valve body 1 offers first passage 1-1, second channel 1-2, the mounting groove of described inclined hole 5-1 upper end communication seals seat 5 gyration center, inclined hole 5-1 lower end is communicated with first passage 1-1.
First passage 1-1, both second channel 1-2 are all curved, and first passage 1-1 is placed in above second channel 1-2.
Sealing seat 5 and valve gap 7 and be respectively equipped with gasket seal 10 between sealing seat 5 and valve body 1.
Working procedure of the present utility model is as follows: when spool 3 is up, first passage 1-1 and second channel 1-2 is interconnected, and medium can circulate smoothly, when spool 3 comes downwards to and compresses valve seat 2, first passage 1-1 and second channel 1-2 disconnects mutually, and now medium can not pass through smoothly; Because first passage 1-1 and second channel 1-2 all designs in S streamlined, can pressure drop be effectively reduced, reduce noise; Inclined hole 5-1 in addition on sealing seat 5 is provided with some, and inclined hole is for being communicated with first passage 1-1 and sealing seat 5 internal cavity.
