Detailed description of the invention
Fig. 1 shows the schematic diagram under hose valve open state.
Fig. 2 shows the schematic diagrames under hose valve closed state.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As depicted in figs. 1 and 2, the utility model provides a kind of hose valve, which includes valve body 1 and fixed peace
Mounted in the intracorporal sebific duct 2 of valve, sebific duct 2 is located on valve body 1 by the step surface that sebific duct both ends and valve body 1 cooperate, and passes through method
Orchid is fixedly installed on valve body 1, has the channel 20 passed through for fluid media (medium) in sebific duct 2, and about 2 sebific duct is respectively equipped with
Casting die 30 and pressing member 32 are additionally provided with the valve rod 3 opened and closed for controlling upper casting die 30 and pressing member 32 on the valve body, work as valve rod
3 when rotating clockwise or counterclockwise, and casting die 30 and pressing member 32 can be driven to make opposite or far from movement, with realize should
Hose valve is turned on or off.Wherein sebific duct generally preferably uses elastic property good rubber material is made.Since valve rod 3 is controlled
The mode that casting die 30 and pressing member 32 move in system is the prior art, therefore its specific structure no longer carries out detailed description herein,
Specific structure can be with reference to the valve core structure in Publication No. CN105952926A.
The hose valve that is there is provided in the present embodiment and the prior art the difference is that, the sebific duct 2 30 He of casting die in face
First annular raised 200 be arranged radially along the sebific duct are formed on the position of pressing member 32, this is first annular raised 200 toward sebific duct
A first annular cavity 202 is protruded and formed on the outer wall of sebific duct in 2, this first annular raised 200 with the one of sebific duct 2 at
Type and obtain, and the wall thickness uniform thickness of first annular raised 200 wall thickness and sebific duct, i.e. sebific duct 2 corresponding upper casting die 30 and under
A shrinkage part collected inside is formed on the position of casting die 32, when so that fluid passing through the shrinkage part, the flow velocity of fluid be will increase,
So that the abrasive material in fluid is not easy to be sticked on the inner wall of shrinkage part, that is, it is not easy to be sticked to first annular raised 200 inner wall
On, and the radian that there is past internal projection due to first annular raised 200, relative to conventional round cambered surface, abrasive material
It can reduce the probability being sticked on first annular raised 200 inner wall, in addition, abrasive material is under the washing away of fluid
It is easier to be flushed away.
With reference to Fig. 1 and Fig. 2, wherein preferably, the upper casting die 30 and pressing member 32 are towards being all arranged on the end of sebific duct
There is the nip portion 300 and 320 to match with first annular cavity 202, since first annular cavity 202 in the present embodiment is each
The section at place is all identical, and to be arc-shaped, therefore the pressing in the nip portion 300 and pressing member 32 on upper casting die 30
Portion 320 is identical arc-shaped structure.Since the nip portion of upper casting die 30 and pressing member 32 is to be located at first annular cavity
Interior, therefore upper casting die 30 and pressing member 32 can play certain supporting role to sebific duct, and closed in the hose valve
In the process, first annular cavity 202 also plays certain position-limiting action to upper casting die 30 and pressing member 32, so that upper casting die 30
It will not be deviated with pressing member 32, so that the effect of its closure is more preferable.
With reference to Fig. 1 and Fig. 2, has at first annular raised 200 middle part and first annular raised 200 coaxial set with this
The second annular protrusion 204 set, second annular protrusion 204 protrude in sebific duct and form one the on the outer wall of sebific duct 2
It is both provided in the nip portion of second ring cavity 206, the upper casting die 30 and pressing member 32 and is matched with the second annular cavity 206
Lug boss 302 and 322, since the section of the second annular cavity 206 throughout is all identical in the present embodiment, and
What it is to be arc-shaped, therefore in 32 nip portion of upper casting die 30 and pressing member is the identical arc-shaped structure of lug boss.Due to
The presence of second ring protrusion 204, when so that fluid passing through shrinkage part, flow velocity increases again, so that the abrasiveness in fluid
Substance is not easy to be sticked on the inner wall of shrinkage part, and abrasive material is also easier to be flushed away under the washing away of fluid, and the second annular
The curvature of protrusion 204 is bigger than the curvature of first annular lug boss 200 and its area again smaller than first annular protrusion area, because
The probability that this abrasive material is sticked on the second annular protrusion 204 is smaller.And the protrusion in upper casting die 30,32 nip portion of pressing member
When the hose valve is closed, the power in nip portion is concentrated on lug boss, which is preferably closed, close in portion
It is more preferable to close performance.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
