As shown in Figure 1 to Figure 3, one embodiment of the present invention provides a kind of slow pressure check valve of easily assembling, and the easy assembling is slow
Pressure check valve includes：Body 1；The body 1 is provided with the runner 2 extended in the same direction with it；One end of the body 1 is provided with and is passed through
The water inlet 3 of the runner 2；The side wall of the body 1 is provided with the delivery port 4 communicated with the runner 2；In the runner 2
Provided with spring 6 and valve element 5；The outer edge surface of the valve element 5 is fitted with the inner wall sealing of the runner 2；Spiral shell in the runner 2
Line is connected with fixture 8；The spring 6 is located between the valve element 5 and the fixture 8；Described one end of spring 6 is fixed on
On the fixture 8, the other end applies pulling force to the valve element 5；The fixture 8 is provided with the through hole passed through for water
83。
The valve element 5 has the first position and the second place along the bearing of trend of main body 1 spaced a predetermined distance；It is described
Valve element 5 will be blocked when being located at the first position between the water inlet 3 and the delivery port 4, and the valve element 5 is located at described the
The water inlet 3 is connected with the delivery port 4 during two positions；In the valve element 5 towards the water inlet 3 one in the runner 2
Side sets restraining position ring block 8；The spacing ring 8 can prevent the valve element 5 from being moved when being located at the first position to the water inlet 3
It is dynamic.
The valve element 5 can be from the first position to described the when being more than the elastic force of the spring 6 by the pressure of water
Move two positions；The valve element 5 can be from the second place to described when being less than the elastic force of the spring 6 by the pressure of water
Move first position.
In the present embodiment, body 1 can be pipe structure.The material of body 1 can be metal, such as steel, iron,
The material such as aluminium and metal alloy.Specifically, the cross section of the body 1 can be toroidal.Valve element 5 constructs for plectane.
Wherein, length of the delivery port 4 along the direction of body 1 is more than length of the outer edge surface of the valve element 5 along the direction of body 1
Degree（The thickness of valve element 5 can be such as considered as）.
As shown in Figure 1 to Figure 3, fixture 8 is threadedly connected in runner 2, and then by rotational fixture 8, fixture 8 can
Moved in runner 2 along runner 2, so as to adjust the original state or initial position of spring 6.When mounted, first by intaking
The spring 6 being fixedly connected, valve element 5 are put into runner 2 by mouth 3, are then put into fixture 8 in water inlet 3, and rotational fixture 8 makes
It is threadedly coupled with runner 2, and is stopped operating when being screwed into precalculated position, and fixture 8 can be fixed by threaded connection
In present position.It can be seen that, by setting fixture 8 very easily to assemble the slow pressure check-valves of the voltage stabilizing, and it is simple in construction,
Advantageously reduce manufacturing cost.
As shown in Figure 2 and Figure 3, the slow pressure check-valves of the voltage stabilizing is assembled to further facilitate, is easy to rotational fixture 8, it is described solid
Determining part 8 has the linkage section 81 being connected with the inner thread of runner 2 and rotational segment 82.The rotational segment 82 is connected to institute
Linkage section 81 is stated back to the spring side, to drive the linkage section 81 to rotate.The external diameter of the rotational segment 82 is less than described
The external diameter of linkage section 81.Wherein, the fixture 8 can be formed in one structure, or Split connection structure, such as rotate
Section 82 is with linkage section 81 by being welded to connect.The rotational segment 82 of the fixture 8 is with linkage section 81 to be coaxially disposed, and workman is in assembling
When can grip linkage section 81 and rotate fixture 8, be connected by the external screw thread of linkage section 81 with the internal thread of runner 2, and then
Fixture 8 is fixed in runner 2.
For ease of the entrance of water, fixture 8 is provided with the through hole 83 of its insertion, and water is after water inlet 3 enters
Moved after through through hole 83 until being applied to the pusher movable valve plug 5 of valve element 5.Specifically, the quantity of the through hole 83 is at least
Three；Through hole 83 described at least three is distributed evenly around the rotational segment 82.As shown in figure 3, shown through hole 83 is four
Individual, four through holes 83 are uniformly distributed around rotational segment 82.
Specifically, delivery port 4 is arranged on the side wall of body 1, its shape and number are simultaneously not intended to be limited in any.Preferably,
Delivery port 4 can be rectangle, and length direction is parallel with the length direction of runner 2.
In the present embodiment, the original state of the spring 6 is compressive state.Specifically, fixation is set in the runner 2
It is equipped with fixed plate 7.The spring 6 is located between fixed plate 7 and valve element 5；The fixed plate 7 is located at the delivery port 4 away from valve
The side of core 5.
In the present embodiment, valve element 5 is located between spring 6 and spacing ring 8.Spring 6 when valve element 5 is in first position
Thrust pulling force is increasing.Wherein, to cause the initial compressed state of spring 6 adjustable, in the spacing ring 8 and the runner 2
Wall is detachably connected.Specifically, the inwall of runner 2 is provided with internal thread, the spacing ring 8 is provided with external screw thread, the limit
Position ring 8 is connected with the inner thread of runner 2.
Valve element 5 is in first position, by the side of water inlet 3 hydraulic pressure to the second place move when, the movement of valve element 5 is default
When distance reaches the second place, water inlet 3 could be connected with delivery port 4.After hydraulic pressure venting, thrust of the valve element 5 in spring 6
（The thrust is the restoring force of valve element）Under return to first position.When valve element 5 is in first position, spring 6 may be at freedom
State（Without compression）, its pre-compressed state can also be in, so as to put on the pre- thrust of valve element 5 one.
When there are water pressure fluctuations in runner 2, water pressure fluctuations are put on valve element 5, and valve element 5 is to the second place（Delivery port
4）Mobile, in the moving process of valve element 5, the easy slow pressure check valve of assembling is in non-connected state all the time, due to water pressure fluctuations
Pressure is held time short and pressure transient, therefore in water pressure fluctuations, valve element 5 passes through to be moved the hydraulic pressure in pre-determined distance
Fluctuation buffering is fallen, and is not in the situation for opening by mistake and opening.
By above description as can be seen that the slow pressure check valve of the easy assembling of present embodiment passes through first to valve element 5
Put and one pre-determined distance is set with the second place, so that occurring valve element 5 during water pressure fluctuations in pipeline can move in pre-determined distance
It is dynamic, and then by water pressure fluctuations venting, therefore, the slow pressure check valve of easy assembling that present embodiment is provided before the second place is reached
Can be effectively prevented from because pipeline hydraulic pressure fluctuate occur open by mistake the problem of opening.
Herein cited any digital value all include between lower limit to higher limit with the lower value of an incremented and
The all values of upper value, the interval that there are at least two units between any lower value and any much higher value.For example, such as
Fruit elaborates the quantity or process variable of part（Such as temperature, pressure, the time）Value be from 1 to 90, preferably from 20
To 80, more preferably from 30 to 70, then purpose is to illustrate that such as 15 to 85,22 are also clearly listed in the specification arrives
68th, 43 to 51,30 to 32 is equivalent.For the value less than 1, it is 0.0001,0.001,0.01,0.1 suitably to think a unit.
