Abstract
A hand valve with high knob strength comprises a valve body, and a valve core is arranged on the valve body. An aluminum alloy fixing sleeve is arranged between the valve core and the valve body, and the lower end of the aluminum alloy fixing sleeve is clamped between the valve core and the valve body. The upper end of the hand valve with the high knob strength is a ring mouth sleeved in a ring sleeve, and the side wall of the ring mouth is provided with a circular protrusion and the circular protrusion is clamped in a circular clamping mouth. The hand valve with the high knob strength has the advantages that when a rotary button is rotated, due to the fact that the lower portion of the rotary button is supported by the ring mouth of the aluminum alloy fixing sleeve, the hand valve with the high knob strength does not shake, and therefore the service life of a valve rod is prolonged and the intensity of the rotary button is improved, at the same time, the rotary button is enabled not to be contacted with the valve body directly, and the rotary button is difficult to damage.
Description
Technical field
The utility model relates to a kind of pneumatic member, particularly a kind of hand valve.
Background technique
We will use various assemblies in pneumatic system, such as joint, stop valve, one-way throttle valve, hand valve, cylinder etc.
The hand valve is an assembly that is used for the switch whole system in the pneumatic system.
Existing hand valve all comprises the valve body of a belt spool, the valve body top is provided with a knob of controlling spool, the knob of prior art all is directly to be fixed on the valve rod of spool, and valve rod swings easily, cause the direct and valve body collision distortion in knob lower end of plastics quality during turning knob, have influence on the follow-up use of valve body.
Summary of the invention
The deficiency easy for the knob that overcomes existing hand valve and the valve body collision is out of shape, the utility model provides a kind of knob intensity high hand valve.
The technical scheme in the invention for solving the technical problem is: the hand valve that a kind of knob intensity is high, comprise a valve body, described valve body one end is provided with a fast interface of tracheae, the described valve body the other end connects a metal interface, described metal interface is provided with outside thread, the fast interface of described tracheae is communicated with by an air flue that is arranged in the valve body with described metal interface, also be provided with a spool that intercepts described air flue on the described valve body, described spool comprises a valve core shell, described valve core shell vertically is provided with valve-rod cavity, described valve-rod cavity downside is provided with the first gas port, described valve-rod cavity laterally is provided with the second gas port, be equipped with valve rod in the described valve-rod cavity, described valve rod upside connects a knob, described valve rod downside connects a piston, described valve-rod cavity is provided with the lifting groove, laterally being provided with projection on the described valve rod is slidedly arranged in the lifting groove, turning knob band ovable valve stem rotates, projection on the described valve rod moves up and down the band ovable valve stem along the lifting groove and moves up and down, thereby the piston of described valve rod downside is followed and mobile can be blocked the first gas port or open the first gas port; The air flue that described the first gas port communicates with the fast interface of tracheae is communicated with, and the air flue that described the second gas port communicates with metal interface is communicated with, and described knob below is provided with an annular groove, and described annular groove is provided with annular bayonet socket; Be provided with the Cuprum alloy fixed cover between described spool and the valve body, described Cuprum alloy fixed cover lower end is arranged between spool and valve body, and the upper end is that a collar extension is inserted in the described annular groove, also is provided with annular projection on the described collar extension sidewall and snaps in the described annular bayonet socket.
Further, described valve body is provided with two positioning holes.Described positioning hole is used for this product fixed arrangement at substrate or support, to put air pipe lines in order.
The utility model in use, turning knob because knob below supported by the collar extension of Cuprum alloy fixed cover, so can not rock, has improved the working life of valve rod, has improved simultaneously the working life of knob.
The beneficial effects of the utility model are: during turning knob, because supported by the collar extension of Cuprum alloy fixed cover below the knob, thus can not rock, so improved the working life of valve rod and the intensity of knob, also so that knob does not directly contact with valve body, knob is not easy to damage simultaneously.
Description of drawings
Fig. 1 is an embodiment's of the utility model schematic representation.
Fig. 2 is A place partial enlarged drawing among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
By reference to the accompanying drawings 1 and 2, the hand valve that a kind of knob intensity is high, comprise a valve body 1, described valve body 1 one ends are provided with a fast interface 2 of tracheae, the described valve body the other end connects a metal interface 3, described metal interface is provided with outside thread, the fast interface 2 of described tracheae is communicated with by an air flue 4 that is arranged in the valve body with described metal interface 3, also be provided with a spool 5 that intercepts described air flue on the described valve body 1, described spool 5 comprises a valve core shell 6, described valve core shell 6 vertically is provided with valve-rod cavity 7, described valve-rod cavity 7 downsides are provided with the first gas port 9A, described valve-rod cavity laterally is provided with the second gas port 9B, be equipped with valve rod 8 in the described valve-rod cavity 7, described valve rod 8 upsides connect a knob 10, described valve rod 8 downsides connect a piston 11, described valve-rod cavity 7 is provided with lifting groove 12, laterally being provided with projection 13 on the described valve rod 8 is slidedly arranged in the lifting groove 12, turning knob 10 band ovable valve stems 8 rotate, projection 13 on the described valve rod 8 moves up and down band ovable valve stem 8 along lifting groove 12 and moves up and down, thereby the piston 11 of described valve rod 8 downsides is followed and mobile can be blocked the first gas port 9A or open the first gas port; The air flue 4 that described the first gas port 9A communicates with the fast interface 2 of tracheae is communicated with, and the air flue 4 that described the second gas port 9B communicates with metal interface 3 is communicated with, and described knob 10 belows are provided with an annular groove 14, and described annular groove 14 is provided with annular bayonet socket 15; Be provided with Cuprum alloy fixed cover 16 between described spool 5 and the valve body 1, described Cuprum alloy fixed cover 16 lower ends are arranged between spool and valve body, the upper end is that a collar extension 17 is inserted in the described annular groove 14, also is provided with annular projection 18 on described collar extension 17 sidewalls and snaps in the described annular bayonet socket 15.
