Abstract
The utility model relates to a throttle stop valve, which comprises a throttle valve core arranged in a valve body. A stop valve core is also arranged in the valve body. The throttle valve core comprises a first throttle valve core. The axis of the first throttle valve core and the axis of the stop valve core are equidirectional or intersectant. A first filter screen is also arranged in the valve body. One end of the first filter screen is big, and the other end of the first filter screen is small. The throttle valve core comprises the first throttle valve core and a second throttle valve core. The first throttle valve core and the second throttle valve core are respectively arranged at both sides of the stop valve core. The first filter screen and a second filter screen are also arranged in the valve body, wherein the first filter screen approaches to the first throttle valve core, and the second filter screen approaches to the second throttle valve core. One end of the first filter screen is big, and the other end of the first filter screen is small; one end of the second filter screen is big; and the other end of the second filter screen is small. The throttle stop valve has the characteristics of simple and reasonable structure, small size, flexibility in operation, low manufacturing cost and wide application range.
Description
Technical field
The utility model relates to a kind of throttle valve, particularly a kind of throttling stop valve.
Background technique
Universal component in the present air-conditioning system: throttle valve and stop valve, it all is single products, be that throttle valve is an independently product, stop valve is another independently product, they need in use to make respectively, install respectively and debugging respectively, brought bigger workload with installation for the making of air conditioner, make us not too satisfied.
The model utility content
The purpose of this utility model aim to provide a kind of simple and reasonable, volume is little, flexible operation, fabricating cost throttling stop valve low, applied widely, to overcome deficiency of the prior art.
A kind of throttling stop valve by this purpose design comprises the throttling valve core that is arranged in the valve body, and its structure characteristic is also to be provided with by spool in the valve body.
Described throttling valve core comprises the first throttle spool, the axis of this first throttle spool with by the axis of spool in the same way or intersect.
Also be provided with first filter screen in the described valve body.
One end of described first filter screen is big, and the other end is little.
Described throttling valve core comprises the first throttle spool and second throttling valve core, and this first throttle spool and second throttling valve core are separately positioned on the both sides by spool.
Also be provided with first filter screen and second filter screen in the described valve body, first filter screen relies on the first throttle spool, and second filter screen relies on second throttling valve core.
One end of described first filter screen is big, and the other end is little; One end of second filter screen is big, and the other end is little.
The utility model ends function by setting up by spool thereby increased on the basis of throttling function in the valve body of throttle valve; And, can also in the valve body of throttle valve, set up first filter screen or second filter screen, it is big that this first filter screen or second filter screen have an end respectively, the structure that the other end is little, can realize capillary tube, stop valve, the incorporate characteristics of filter, thereby can reduce fabricating cost, and can reduce the workload of installing and debugging, increase work efficiency.
The utlity model has simple and reasonable, volume is little, flexible operation, low, the advantage of wide range of application of fabricating cost.
Description of drawings
Fig. 1 is the utility model first embodiment's a structural representation.
Fig. 2 is the routine structural representation that the utility model second is implemented.
Among the figure: 1 for ending spool, and 2 is valve body, and 3 is the first throttle spool, and 4 is first filter screen, and 5 is first valve gap, and 6 is second throttling valve core, and 7 is second filter screen, and 8 is second valve gap.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
First embodiment
Referring to Fig. 1, this throttling stop valve comprises the throttling valve core that is arranged in the valve body 2, also is provided with by spool 1 in the valve body 2.
In the present embodiment, described throttling valve core comprises first throttle spool 3, the axis of this first throttle spool 3 with by the axis of spool 1 in the same way or intersect.Only provided the concrete structure that intersects among Fig. 1.
Also be provided with first filter screen 4 in the valve body 2.One end of first filter screen 4 is big, and the other end is little.This first filter screen 4 can be provided with in the same way with first throttle spool 3; Also can be separately positioned on the different direction of valve body 2, see Fig. 1.
Present embodiment is three-in-one with capillary tube, stop valve and filter, can realize the function that one-way throttle ends.
Throttling valve core in the present embodiment can be replaced after it wearing and tearing takes place or damages.Pull down and can carry out the displacement of throttling valve core being arranged on pipe nipple cover on the valve body 2, the pipe nipple cover is threaded with valve body 2.First valve gap, 5 lids are connected on pipe nipple and put.
Second embodiment
Referring to Fig. 2, the described throttling valve core in the present embodiment comprises the first throttle spool 3 and second throttling valve core 6, and this first throttle spool 3 and second throttling valve core 6 are separately positioned on the both sides by spool 1.The axis of first throttle spool 3 is provided with in the same way with the axis that ends spool 1.
Also being provided with first filter screen 4 and second filter screen, 7, the first filter screens 4 in the described valve body 2 relies on first throttle spool 3, the second filter screens 7 and relies on second throttling valve core 6.One end of first filter screen 4 is big, and the other end is little; One end of second filter screen 7 is big, and the other end is little.
Present embodiment can be realized the function that bidirectional throttle ends with capillary tube, one-way valve, stop valve and filter four unifications.
All the other are not stated part and see first embodiment, no longer repeat.
