technical field

The utility model belongs to the technical field of machinery and relates to a flow regulating valve, in particular to a four-way flow regulating valve.

Background technique

Valves are widely used in pipeline engineering. Commonly used valves are composed of valve body, valve core, valve stem and handwheel. The valve stem and valve core are driven by the handwheel to open and close the valve. At present, the most commonly used valve is a straight-through valve, but it can only be opened and closed in one direction. It is not suitable for more complicated heating pipeline systems, and its function is relatively single. When used, it can only pass cold water or hot water. . In addition, there is also a three-way valve, which has two water inlets and one water outlet, which is more suitable for heating pipes. The two water inlets are respectively connected to cold water pipes and hot water pipes. After being mixed in the body, it flows out from the water outlet for users to use. However, the existing heating pipeline system is not only for single use, but the three-way valve has only one water outlet, which cannot be used by multiple people.

In order to solve the problems existing in the three-way valve, people have designed a four-way reversing ball valve. The valve is an LL-type reversing valve with two water inlets and two water outlets. °, the flow direction of the medium is switched once, so as to realize two in and two out of the flow channel. However, due to the inconsistent distribution of pipelines in each pipeline system, after the traditional four-way ball valve is produced and formed, the positions of the two water inlets and the two outlets are designed and cannot be changed. When it is well connected with the pipes distributed in the piping system used, it needs to be purchased again.

In this embodiment, the end cover 8 is square, and there are several protruding connecting lugs 8c on the outside of the end cover 8 .

As shown in Figures 1-4, the valve core 2 is plate-shaped, and the upper and lower ends of the valve core 2 have disc-shaped positioning plates 2a respectively, and both sides of the valve core 2 have arc-shaped sealing surfaces 2b respectively. 2. A valve stem 4 is fixedly connected to the positioning plate 2a at the upper end. The upper end of the valve stem 4 protrudes from the upper end of the valve body 1 to the outside of the end cover 8. The valve stem 4 is covered with a valve plate 3. The valve plate 3 is disc-shaped. The surface of the end cover 8 has a fitting cavity 8 a with the same shape as the valve plate 3 , the valve plate 3 is embedded in the fitting cavity 8 a, and the surface of the valve plate 3 is flush with the surface of the end cover 8 . The valve stem 4 is also sleeved with a gear indicator plate 7, the center of the valve plate 3 has an annular protrusion 3c, the gear indicator plate 7 is sleeved outside the annular protrusion 3c, and the valve plate 3 has a valve stem 4 The location is the four installation holes 3b evenly distributed in the circumferential direction of the center of the circle. The gear indicator plate 7 has installation holes 2 7a corresponding to the installation holes 3b, and the fitting cavity 8a on the surface of the end cover 8 has corresponding installation holes. Three, the valve plate 3 and the gear indicating plate 7 are fixed to the end cover 8 through the fasteners 6 passing through the second installation hole 7a, the first installation hole 3b and the third installation hole in sequence.

The valve stem 4 is sleeved with a handwheel 5, and the outer side of the upper end of the valve stem 4 has an inclined positioning surface 4a, and the inner side of the handwheel 5 corresponds to a protruding positioning block 5c, and the outer surface of the positioning block 5c fits with the positioning surface 4a , so that the valve stem 4 and the handwheel 5 are fixed in the circumferential direction. The annular protrusion 3c of the valve plate 3 has a protruding limit block 3a, and the bottom of the hand wheel 5 has an arc-shaped limit port 5a, and the limit block 3a is located in the limit port 5a, so that the valve stem 4 rotates The rotation stroke of the valve rod 4 is limited during this time.

In this embodiment, the upper end of the valve stem 4 has a positioning hole. After the hand wheel 5 is sleeved on the upper end of the valve stem 4, it is fixed by the positioning screw that penetrates from the top of the hand wheel 5 into the positioning hole at the upper end of the valve stem 4. .

When the four-way flow regulating valve is in use, it is the same as the common four-way valve, and the two ports on the valve body 1 are cold and hot water inlets, and the remaining two ports are water outlets. The position block 3a cooperates with the limit port 5a of the hand wheel 5 to limit the rotation angle and rotation formation of the valve stem 4, which actually means that the opening of one of the water inlets on the valve body 1 is controlled. Limit, and after the valve stem 4 rotates, the position of the indicator block 5b on the outside of the hand wheel 5 is opposite to the gear position on the gear indicator plate 7 to display the current opening corresponding to the water inlet.

In this four-way flow regulating valve, since the limit block 3a is set on the valve plate 3, and the valve plate 3 is fixed on the valve body 1 through the fastener 6, it means that the valve plate 3 and the valve body 1 between is detachable. At the same time, the cooperation between the limit block 3a and the limit port 5a on the hand wheel 5 is used to limit the rotation angle of the valve stem 4. Therefore, when the position of the limit block 3a changes, the position of the corresponding water inlet will naturally change. change, so that the positions of the two water inlets will change at the same time, which means that the four-way flow regulating valve can freely select the water inlet and the water outlet according to needs.

The operation of selecting the water inlet and the water outlet is as follows: since the valve plate 3 and the gear indicator plate 7 are fixed on the end cover 8 by the fastener 6, the fastener 6 is removed first, so that the valve plate 3 is in the It can be freely rotated relative to the valve body 1, then remove the gear indicator plate 7 from the valve plate 3, and then rotate the valve plate 3 around the valve stem 4 to ensure that the limit block 3a on the valve plate 3 rotates to the valve It needs to be set as the port of the water inlet on the body 1, so that one of the water inlets is selected, and then the gear indicator plate 7 is re-socketed to the ring-shaped protrusion 3c on the valve plate 3. It should be noted that, in order to enable the gear indicator plate 7 to accurately display the opening of the selected water inlet, the gear indicator plate 7 also needs to be rotated through the same angle and then fixed again with the fastener 6 . After one of the water inlets is selected, the position of the other water inlet on the valve body 1 is naturally determined due to the existence of the limiting block 3a and the limiting port 5a.

It can be seen that through the above structure, the four-way flow regulating valve can arbitrarily select the positions of the water inlet and the water outlet of the valve according to actual needs, and this method can well improve the application of the four-way flow regulating valve. It is flexible and can meet various demands, realizing that one valve body 1 has multiple ways of water inlet and outlet. Since the valve body 1 is four-way, and the valve core 2 in this four-way flow regulating valve is plate-shaped, the valve core 2 forms a seal between the sealing surface 2b on both sides and the inner wall of the valve body 1, so no matter No matter how the positions of the water inlet and the water outlet change, the sealing between the valve core 2 and the valve body 1 and the normal control of the valve core 2 on the opening will not be affected.
