Description
Technical field
The present invention relates to the spool that uses in a kind of inlet/outlet one-way valve group of reciprocating pump.
Background technique
Advancing in the reciprocating pump, the function of outlet one-way valve group is for sucking or discharge medium, advancing in traditional reciprocating pump, outlet one-way valve group as shown in Figure 1, comprise spool, valve seat, support etc., wherein, spool is a solid construction, spool comprises guide rod, support plate and the guide vane that play the guiding role that is contained in lower end of the guide rod, support plate is positioned at the conical cavity on valve seat top, guide vane cooperates with the cylinder chamber of the bottom of valve seat, the sealing gasket that cooperates with the conical cavity liquid sealing of valve seat is equipped with in the top of support plate, sealing gland is equipped with in the top of sealing gasket, the top of described guide rod can be socketed on up and down in the fixed support slippingly, is connected with Returnning spring between described fixed support and the described sealing gland.
During work, the conical surface that pressure fluid cooperates with valve seat from sealing gasket flows in the valve body, and support plate is held up, and makes on the spool and moves, and the Returnning spring that is contained between fixed support and the Sealing is compressed; When the spool bottom does not have pressure fluid, under the effect of Returnning spring, valve core reset, the one-way valve group is closed.Because spool adopts solid construction, spool is from great, when spool is closed, impulsive load to valve seat is big, causes valve seat, spool impact shock big, has a strong impact on the spool working condition, not only make the valve group big in when work vibration, the noise height, and shortened working life of spool.
Summary of the invention
Impact deficiency big, that noise is high, vibration is big, working life is short in order to overcome the spool that uses in traditional reciprocating pump inlet/outlet one-way valve group when great, the work, impact when the invention provides a kind of in light weight, work little, vibration is little, noise is low, the reciprocating pump import and export one-way valve group hollow structure spool of prolongation in working life.
The present invention adopts following technological scheme:
A kind of reciprocating pump turnover one-way valve group hollow structure spool, comprise guide rod, support plate and the guide vane that play the guiding role that is contained in lower end of the guide rod, described support plate is positioned at the conical cavity on valve seat top, the outer periphery of described support plate and the cone match of described conical cavity, described guide vane cooperates with the cylinder chamber of the bottom of valve seat, the Sealing that cooperates with the conical cavity liquid sealing of valve seat is equipped with in the top of described support plate, sealing gland is equipped with in the top of described Sealing, described Sealing and sealing gland are socketed in the bottom of described guide rod, the top of described guide rod can be socketed on up and down in the fixed support slippingly, be connected with Returnning spring between described fixed support and the described sealing gland, longitudinally be provided with cavity in the described guide rod, described cavity is a blind hole.
Preferably, described cavity communicates with the upper end of guide rod.
Be provided with guide sleeve between described fixed support and the described guide rod.
Technical conceive of the present invention is: under the prerequisite of rigidity that guarantees spool and intensity, the guide rod of spool is designed to hollow structure, can reduce the deadweight of spool, when spool is closed, can reduce the impulsive load of spool to valve seat, impact shock is little during spool work, and the work of valve group is more steady, noise is low, improve the working condition of valve group, prolonged the working life of spool.
Beneficial effect of the present invention: owing to reduced the deadweight of spool, when the work of valve group is closed, effectively reduce spool, the working condition of spool is improved, thereby prolonged the working life of spool to the impulsive load of valve seat and the vibration of spool.
Description of drawings
Fig. 1 is the structural representation that traditional reciprocating pump passes in and out the one-way valve group.
Fig. 2 is the structural representation of hollow structure spool of the present invention.
Fig. 3 is the structural representation of the valve group of employing hollow structure spool.
Embodiment
Referring to Fig. 2-3: a kind of reciprocating pump turnover one-way valve group is with hollow structure spool 1, comprise guide rod 7, support plate 10 and the guide vane that play the guiding role 8 that is contained in guide rod 7 lower ends, described support plate 10 is positioned at the conical cavity 11 on valve seat 6 tops, the cone match of the outer periphery of described support plate 10 and described conical cavity 11, described guide vane 8 cooperates with the cylinder chamber 12 of the bottom of valve seat 6, the sealing gasket 5 that cooperates with conical cavity 11 liquid sealings of valve seat 6 is equipped with in the top of described support plate 10, sealing gland 4 is equipped with in the top of described sealing gasket 5, described sealing gasket 5 and sealing gland 4 are socketed in the bottom of described guide rod 7, the top of described guide rod 7 can be socketed in the fixed support 3 up and down slippingly, be provided with guide sleeve 2 between described fixed support 3 and the described guide rod 7, be connected with Returnning spring 13 between described fixed support 3 and the described sealing gland 4, longitudinally be provided with cavity 9 in the described guide rod 7, described cavity 9 is arranged on the center of described guide rod 7, and described cavity 9 is a blind hole.Described cavity 9 communicates with the upper end of guide rod 7.Described cavity 9 is not arranged to the structure of up/down perforation, is in order to make the pressure flow physical efficiency produce effective function power, to be unlikely to release from the cavity 9 of up/down perforation.
During work, the conical surface that pressure fluid cooperates with valve seat 6 from sealing gasket 5 flows in the valve body, and support plate 10 is held up, and makes on the spool and moves, and sealing gasket 5 and sealing gland 4 move on also, and the Returnning spring 13 that is contained between fixed support 3 and the sealing gland 4 is compressed; When the spool bottom does not have pressure fluid, under the effect of Returnning spring 13, valve core reset, the one-way valve group is closed, and when the valve group was closed, spool can have impact force to valve seat, can produce corresponding impact shock on valve seat, the spool.
The guide rod of the spool that traditional reciprocating pump turnover one-way valve group adopts is a solid construction, and this just causes the spool deadweight bigger.Hollow structure spool of the present invention under the prerequisite of rigidity that guarantees spool and intensity, is designed to hollow structure with the guide rod of spool, can effectively reduce spool deadweight about 20%.Because the reduction of spool deadweight when the work of valve group is closed, can reduce the impulsive load of spool to valve seat, reduces the vibration of valve seat, spool, and the working condition of spool is improved, and has prolonged the working life of spool.
