Abstract
The utility model discloses a valve in door closer, include the valve body that is used for with door closer body threaded connection, the bottom of this valve body is seted up only has the V of two lateral walls type groove, the grooving has been seted up on the top of valve body, the embedded O type sealing washer that is equipped with of grooving, this utility model structure is simple, can the micro - velocity of flow of adjusting this internal hydraulic oil of door closer.
Description
Technical field
The utility model relates to a kind of door closer, and more particularly, it relates to the valve in a kind of door closer.
Background technique
Door closer is a hydraulic pressure device for a upper spring-like, by compressing rear release after door being opened, automatically being shut by door, the effect of spring-like door, after can ensureing that door is unlocked, accurately, being timely closed to initial position.
At present, the door closer on market, it comprises door closer body and rocking arm, and door closer body is fixed on door/doorframe, and one end is connected with door closer body, and the other end is connected on doorframe/door.The scope that this door closer is suitable for is narrower, and the time of closing the door is not easy to control, and is not suitable for the special populations such as old man, children and handicapped people, therefore, needs a kind of device that can control hydraulic oil flow velocity in door closer body.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide the valve in a kind of door closer solved the problem.
For achieving the above object, the utility model provides following technological scheme:
A valve in door closer, comprises the valve body for being threaded with door closer body, and the bottom of this valve body offers the V-type groove only having two sidewalls, and the top of described valve body offers grooving, is embedded with O RunddichtringO in described grooving.
The utility model is set to further: described V-type groove is 15 ﹪ ~ 25 ﹪ of valve body length in the length of valve body axis.
The utility model is set to further: described valve body comprises first paragraph and second segment, and the external diameter of first paragraph is less than the radius of second segment, and described V-type groove is opened on first paragraph, and second segment is provided with outside thread.
The utility model is set to further: described V-type groove is 30 ﹪ ~ 60 ﹪ of first paragraph diameter in the length of valve body radial direction.
The utility model is set to further: one section of described second segment offers interior hexagonal groove.
By adopting technique scheme, valve body is threaded with door closer body, rotating valve body make V-type groove on it near or away from the oil duct on door closer body, the effect of regulator solution force feed flow velocity can be realized, the large and small effect reaching fine setting that this valve body is connected by regulating V-type groove and oil duct, O RunddichtringO, for improving the sealing of this valve body and door closer body, prevents hydraulic oil from leaking outside.
Accompanying drawing explanation
Fig. 1 is the schematic diagram 1 of the valve embodiments in a kind of door closer of the utility model;
Fig. 2 is the schematic diagram 2 of the valve embodiments in a kind of door closer of the utility model.
In figure: 1, valve body; 11, first paragraph; 12, second segment; 3, V-type groove; 4, outside thread; 5, hexagonal groove; 6, grooving; 7, O RunddichtringO.
Embodiment
Referring to figs. 1 through Fig. 2, the valve embodiments in a kind of door closer of the utility model is described further.
Valve in a kind of door closer, comprise the valve body 1 for being threaded with door closer body, the bottom of this valve body 1 offers the V-type groove 3 only having two sidewalls, and the top of described valve body 1 offers grooving 6, is embedded with O RunddichtringO 7 in described grooving 6.Valve body 1 is threaded with door closer body, rotating valve body 1 make V-type groove on it 3 near or away from the oil duct on door closer body, the effect of regulator solution force feed flow velocity can be realized, the large and small effect reaching fine setting that this valve body 1 is connected by regulating V-type groove 3 and oil duct, O RunddichtringO 7, for improving this valve body 1 and the sealing of door closer body, prevents hydraulic oil from leaking outside.
Described V-type groove 3 is 15 ﹪ ~ 25 ﹪ (in order to better hydraulic control oil flow velocity, preferably 20 ﹪) of valve body 1 length in the length of valve body 1 axis.Described valve body 1 comprises first paragraph 11 and second segment 12, and the external diameter of first paragraph 11 is less than the radius of second segment 12, and described V-type groove 3 is opened on first paragraph 11, and second segment 12 is provided with outside thread 4.Described V-type groove 3 is 30 ﹪ ~ 60 ﹪ (in order to better hydraulic control oil flow velocity, preferably 40 ﹪) of first paragraph 11 diameter in the length of valve body 1 radial direction.In order to prevent the intrinsic hydraulic oil of door closer from leaking outside, second segment 12 and door closer body realize being connected without friction sealed, and when valve body 1 rotation moves upward, three oil ducts controlled by this valve body 1 in door closer body can conducting.
One section of described second segment 12 offers interior hexagonal groove 5.In hole valve body 1 can being sunk to completely door closer body is offered, be convenient to while valve body 1 rotates, improve the attractive in appearance, generous of door closer entirety.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (5)
