Abstract

The utility model belongs to valve field, in particular to a kind of hand-operated direction valve.A kind of hand-operated direction valve, including valve body and handle, the handle are detachably connected with valve body；Spool is equipped in the valve body, the spool tail end connects the pushing meanss of a control valve core aperture, and the limiter of restriction pushing meanss displacement is set between the handle and pushing meanss.The accurate control to manual reverse of direction valve opening is realized by the way that limiter is arranged between handle and valve body.

Description

A kind of hand-operated direction valve

Technical field

The utility model relates to valve technology fields, and in particular to a kind of hand-operated direction valve.

Background technique

Reversal valve is the directional control valve with two or more liquid forms and more than two hydraulic fluid ports, is to realize hydraulic oil stream Communication, cutting and commutation and discharge degree and sequentially-operating control valve.By the side of the relative motion of spool and valve body To control valve.There are rotary valve and two kinds of side valve type.The operating position number stopped in valve body by spool is divided into two, three etc.； It is logical etc. to be divided into two-way, threeway, four-way and six by the oil circuit number being connected with valve body；There is manual, machine in the way of operating valve core movement Dynamic, the electronic, patterns such as surge, is electro-hydraulic.

Existing reversal valve mostly uses magnet control, and when use needs to be powered and service life is shorter.Although city Also there is the reversal valve manually controlled on face, but there is and be unable to accurately control aperture handle and technical problem easy to damage.

Utility model content

The purpose of the utility model is to provide a kind of hand-operated direction valves, solve the above technical problem.

The technical issues of the utility model is solved can be realized using following technical scheme:

A kind of hand-operated direction valve, including valve body and handle, the handle and the valve body detachable connection；The valve body Interior to be equipped with spool, the spool tail end connects the pushing meanss of a control valve core aperture, sets one between the handle and pushing meanss Limit the limiter of pushing meanss displacement.

The limiter is using limit clip.

The pushing meanss use push rod.

The pushing meanss and valve core chamber are equipped with the reset spring by valve core reset to closure initial position.

The external control oil disengaging access of spool, the control oil disengaging access are equipped with multiple inserting throttle orifices.

The control oil disengaging access is equipped with multiple plug-in dampers.

The handle and push rod, which are adopted, to be hinged.

The handle is connected with push rod using pin shaft.

The handle is connect with valve body using pin shaft.

The utility model has the advantages that due to the adoption of the above technical scheme, the utility model between handle and valve body by being arranged limiter Realize the accurate control to manual reverse of direction valve opening.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1, valve body, 2, handle, 3, spool, 4, reset spring, 5, push rod, 6, limit clip.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face, which combines to be specifically illustrating, is further described the utility model.

Referring to Fig.1, a kind of hand-operated direction valve, including valve body 1 and handle 2 are equipped with spool 3 in the inside of valve body 1.Spool 3 The control oil access of external multiple control oil disengaging, is arranged plug-in throttle orifice on controlling oily access, is used for entering valve Control oil oil mass in body 1 carries out throttling control.Plug-in damper is also added on the inner wall of control oil circuit, is used for Handle 2 carries out the spool 3 generated when folding or switching operation vibration to spool 3 and is effectively controlled.It is also set at 3 both ends of spool There are reset spring 4 and push rod 5.Wherein the push rod 5 close to 2 side of handle is equipped with limit clip 6, and the limit setting of clip 6 is pushing away Bar 5 leaks out at the 1/2 ~ 1/3 of 1 part of valve body when not pushing spool 3.

In use, operation handle 2 is rotated, push rod 5 is pushed to compress reset spring 4, and then generates spool 3 Certain aperture.When spool 3 reaches required aperture, stop the operation to handle 2, limiting the engaging push rod 5 of clip 6 at this time makes It cannot be subjected to displacement because of restoring force of the generation of reset spring 4, so that the aperture to spool 3 is accurately controlled.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
