Description
Technical field
The utility model relates to the mechanical type one-way valve, especially relates to the bottom valve that is used for two flexible double-action hydraulic vertical props.
Background technique
Bottom valve is mainly used in the flexible order of the two flexible double-action hydraulic vertical prop secondary cylinders of control and the post of living, and keeps secondary cylinder to obtain the resistance identical with first-stage cylinder.Because two flexible double-action hydraulic vertical props how use under coal mine, and it is comparatively complicated to be used in the bottom valve structure of two flexible double-action hydraulic vertical props at present, owing to be subjected to the restriction in space, down-hole, this just brings inconvenience to maintenance, the replacing of down-hole.
The model utility content
The utility model purpose is to provide a kind of simple and compact for structure, bottom valve that is used for two flexible double-action hydraulic vertical props of being convenient to safeguard.
For achieving the above object, the utility model can be taked following technical proposals:
Bottom valve described in the utility model, it comprises valve body, be arranged on valve seat, spool in the described valve body valve pocket, described valve pocket is the cavity that runs through valve body, described valve seat is arranged in the annular groove at valve body left port place, described spool is connected in an end of valve rod and is positioned at outside the valve body left port, and the other end of described valve rod extends outside the valve body right output port, and the valve body right output port is passed through seal ring seal; Be connected with bonnet at valve body left port thread seal, be provided with pressure spring at described bonnet inner chamber; Offer runner respectively at bonnet side wall, body wall.
For improving working life, described valve seat adopt polyformaldehyde material make and with described spool cone match; In described valve pocket, be positioned at body wall runner mouth place and be provided with liquid filter assemblies.
The utility model advantage is simple and compact for structure, during maintenance described bonnet is screwed off and can safeguard a valve left side, spool with the spool taking-up of valve rod one.For improving the working life of described bottom valve, valve seat adopt polyformaldehyde material make and with described spool cone match.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, bottom valve described in the utility model, it comprises valve body 1, be arranged on valve seat 3, spool 4 in described valve body 1 valve pocket 2, described valve pocket 2 is for running through the cavity of valve body 1, and described valve seat 3 is arranged in the annular groove at valve body 1 left port place, and described spool 4 is connected in an end of valve rod 5 and is positioned at outside valve body 1 left port, the other end of described valve rod 5 extends outside valve body 1 right output port, and valve body 1 right output port is by seal ring 6 sealings; Be connected with bonnet 7 at valve body 1 left port thread seal, be provided with pressure spring 8 at described bonnet 7 inner chambers; Offer runner 9,10 respectively at bonnet 7 sidewalls, valve body 1 sidewall.For improving working life, valve seat 3 adopt polyformaldehyde materials make and with spool 4 cone match; In valve pocket 2, be positioned at 10 mouthfuls of places of valve body 1 sidewall runner and be provided with liquid filter assemblies 11.
Claims (3)
1, a kind of bottom valve, it comprises valve body (1), be arranged on valve seat (3), spool (4) in described valve body (1) valve pocket (2), it is characterized in that: described valve pocket (2) is for running through the cavity of valve body (1), described valve seat (3) is arranged in the annular groove at valve body (1) left port place, described spool (4) is connected in an end of valve rod (5) and is positioned at outside valve body (1) left port, the other end of described valve rod (5) extends outside valve body (1) right output port, and valve body (1) right output port is by seal ring (6) sealing; Be connected with bonnet (7) at valve body (1) left port thread seal, be provided with pressure spring (8) at described bonnet (7) inner chamber; Offer runner (9,10) respectively at bonnet (7) sidewall, valve body (1) sidewall.
2, bottom valve according to claim 1 is characterized in that: described valve seat (3) adopt polyformaldehyde material make and with described spool (4) cone match.
