Abstract
The utility model provides a hand-operated valve. The hand-operated valve comprises a valve body. An open slot is formed in the valve body axially, a core sleeve is fixedly installed in the open slot, the outer sidewall of the upper end of the core sleeve is provided with an outer notch; the inner sidewall of the upper end of the open slot is provided with an inner notch whose position corresponds to the position of the outer notch and whose shape and size are matched with the shape and size of the outer notch. The outer notch and the inner notch are jointed and combined correspondingly to form a pin hole slot, a fixed pin is installed in the pin hole slot, and the core sleeve is fixedly connected with the valve body through the fixed pin. According to the utility model, by installing the fixed pin between the core sleeve and the valve body, the fixation between the core sleeve and the valve body is realized through the fixed pin, the rotation of the core sleeve in the valve body can be effectively avoided, the service life of the hand-operated valve can be prolonged, the utilization and replacement cost of the hand-operated valve is reduced, and through the fixed pin, the positioning and installation of the core sleeve and the valve body of the hand-operated valve can be realized rapidly.
Description
Technical field
The utility model belongs to the printer field, and what be specifically related to is a kind of for controlling the hand-operated valve of printer nozzle ink-jet.
Background technology
Ink-jet printer refers to that the ink-jetting style of current ink-jet printer mainly contains micro-piezoelectric type and hot bubble type by ink droplet being ejected on print media to the printing device that forms word or image, and at first micro-piezoelectric ink jet slightly shrinks under the control of signal; Then element produces once larger extension, and ink droplet is released to nozzle; The moment that will fly away from nozzle at ink droplet, element can be shunk again, ink level is shunk from nozzle, thereby make the ink droplet liquid level precisely controlled, and the ink droplet of ejection has perfect shape and correct heading at once; Hot-bubble ink-jetting, by ink heating, expansion, compression at short notice, is ejected into ink on printing paper and forms ink dot, increases the stability of ink droplet color, realizes high-speed, high-quality printing.No matter be micro-piezoelectric type or hot bubble type; all need China ink is penetrated from nozzle; just can reach printing effect preferably; and China ink ejection from nozzle all relies on hand-operated valve to be controlled to adjust; but hand-operated valve is after using a period of time at present; often there will be core retainer plate to rotate in valve body, the problem that causes ink nozzle to stop up.
The utility model content
For this reason, the purpose of this utility model is to provide a kind of hand-operated valve, by a steady pin is installed between core retainer plate and valve body, realizes the fixing of core retainer plate and valve body, avoids occurring that core retainer plate rotates in valve body, the problem that causes ink nozzle to stop up.
The purpose of this utility model is achieved through the following technical solutions.
A kind of hand-operated valve, comprise valve body (1), axially be provided with an open slot (9) in described valve body (1), be installed with core retainer plate (2) in described open slot (9), the lateral wall of described core retainer plate (2) upper end is provided with an outer breach (10); The madial wall of described open slot (9) upper end is provided with the interior breach (7) of and shape size corresponding with described outer breach (a 10) position coupling, described outer breach (10) splice and combine into a pin-and-hole groove corresponding to interior breach (7), steady pin (3) is installed in described pin-and-hole groove, and described core retainer plate (2) is fixed together by described steady pin (3) and valve body (1).
Preferably, spool (4) is installed in described core retainer plate (2), is provided with leader (5) on described spool (4).
Preferably, radially be provided with a nozzle bore (8) that runs through valve body (1), core retainer plate (2) and spool (4) in described valve body (1).
Preferably, described outer breach (10) is half-cylindrical open slot with interior breach (7).
The utility model compared with prior art, beneficial effect is: the hand-operated valve that the utility model provides, by a steady pin is installed between core retainer plate and valve body, utilize this steady pin to realize fixing between core retainer plate and valve body, effectively avoid core retainer plate to rotate in valve body, extended the service life of hand-operated valve, reduced the use replacement cost of hand-operated valve, and, by steady pin, can realize fast location and the installation of core retainer plate and the valve body of hand-operated valve.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model hand-operated valve.
Identifier declaration in figure: valve body 1, core retainer plate 2, steady pin 3, spool 4, handle 5, valve gap 6, interior breach 7, nozzle bore 8, open slot 9, outer breach 10.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 the structural representation that Fig. 1 is the utility model hand-operated valve.The utility model provides a kind of hand-operated valve, and it is mainly used in solving current ink-jet printer hand-operated valve after using a period of time, easily occurs that core retainer plate rotates in valve body, the problem that causes ink nozzle to stop up.
Wherein hand-operated valve described in the utility model is arranged on the head of printer, and it includes valve body 1, core retainer plate 2, spool 4, handle 5 and valve gap 6.
Along being provided with an open slot 9 on valve body 1 axial direction, described open slot 9 upper end open, lower end, through valve body 1, is not provided with in the radial direction one at valve body 1 and runs through whole valve body 1, and the nozzle bore 8 be communicated with open slot 9, for spraying ink.
Wherein the madial wall in open slot 9 upper ends is provided with the interior breach 7 of a semi-cylindrical form, lateral wall in core retainer plate 2 upper ends also is provided with the outer breach 10 of a semi-cylindrical form, and when core retainer plate 2 is arranged in open slot 9 fully, interior breach 7 can form a columniform pin-and-hole groove with the corresponding splicing of outer breach 10, and correspondence is provided with a steady pin 3 in this pin-and-hole groove, by described steady pin 3, core retainer plate 2 and valve body 1 can be fixed together, to prevent occurring that because of long-time the use situation of rotating occurs between the two.
The utility model between the core retainer plate of conventional manual valve and valve body in use for some time, easily occur that core retainer plate spins in the valve body the inside, and cause the ineffective problem of hand-operated valve, correspondence is improved, increased a steady pin between valve body and core retainer plate, valve body and core retainer plate have been fixed, fundamentally solved valve body and core retainer plate and the problem of spinning occurred, the utlity model has simple in structure, be easy to processing, cost is low, practical, and can be applicable to the advantage such as most of hand-operated valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
