Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
A flange-type hydraulic control valve 100 according to an embodiment of the present invention is described below with reference to fig. 1.
According to the utility model discloses flange formula water conservancy control valve 100, include: the valve comprises a valve body 1, a valve cover 2, a stop part 3, a rubber cover 4 and a spring 5.
Wherein, the axial both ends (as the left and right ends that fig. 1 shows) of valve body 1 are equipped with valve inlet 1a and valve outlet 1b respectively, and valve inlet 1a and valve outlet 1b department can be equipped with flange joint spare 11 respectively, and flange joint spare 11 can be connected with the pipeline. An open port may be formed on a sidewall of the valve body 1, and a flow space respectively communicating with the valve inlet 1a, the valve outlet 1b and the open port is formed in the valve body 1. The bonnet 2 is coupled to the valve body 1 to seal the open opening. For example, as shown in fig. 1, the valve body 1 and the bonnet 2 may be connected using a bolt assembly 6.
As shown in fig. 1, a portion of the valve body 1 may be projected toward a direction close to the bonnet 2 (upward direction as shown in fig. 1) to form a stopper 3, and a top of the stopper 3 may be formed as a plane. The rubber cover 4 may be disposed between the valve cover 2 and the valve body 1 and the rubber cover 4 may be recessed toward a direction close to the stopper 3, that is, the rubber cover 4 may be formed in a hemispherical shape, and the bottom of the rubber cover 4 may be provided with two sealing protrusions 41 disposed at an interval and extending in a radial direction of the valve body 1.
The two ends of the spring 5 in the axial direction (the upper and lower ends as shown in fig. 1) can respectively abut against the valve cover 2 and the rubber cover 4, the flange-type hydraulic control valve 100 can have a conducting state and a blocking state, in the blocking state, the spring 5 can drive the rubber cover 4 to abut against the abutting piece 3, and the two sealing protrusions 41 can abut against the opposite walls of the abutting piece 3, so that the communication space can be partitioned into a first chamber 1c communicated with the valve inlet 1a and a second chamber 1d communicated with the valve outlet 1 b; in the conducting state, the fluid pressure in the first chamber 1c can drive the spring 5 to extend and contract so as to drive the rubber cover 4 to separate from the stopping piece 3. At this time, the first chamber 1c is communicated with the second chamber 1d, and the fluid can be circulated through the flange-type hydraulic control valve 100.
Specifically, when fluid needs to be supplied, the fluid pressure in the first chamber 1c may be increased, and when the fluid pressure is greater than a set value, the fluid pressure may push the rubber cover 4 and the spring 5 to contract, the rubber cover 4 may be separated from the stopper 3, and at this time, the first chamber 1c and the second chamber 1d communicate with each other, and the fluid may enter the second chamber 1d through the first chamber 1c and be discharged through the valve outlet 1 b. When the flange-type hydraulic control valve 100 needs to be shut off, the fluid pressure in the first chamber 1c can be reduced, the spring 5 drives the rubber cover 4 to move towards the direction close to the abutting piece 3 and abut against the abutting piece 3 under the action of the elastic force, at this time, the two sealing protrusions 41 can abut against the opposite walls of the abutting piece 3, so that the first chamber 1c and the second chamber 1d can be separated, and the flange-type hydraulic control valve 100 is shut off.
As shown in fig. 1, the inner diameters of the first chamber 1c and the second chamber 1D may be the same, and the diameter D of the first chamber 1c and the thickness D of the rubber cover 4 may satisfy the relationship: D/D is more than or equal to 5 and less than or equal to 10. It can be understood that when the value of D/D is too large, the thickness of the rubber cover 4 is much smaller than the diameter of the first chamber 1c, so that in the cut-off state, the fluid in the first chamber 1c can easily push up the rubber cover 4, thereby causing the leakage phenomenon of the flange-type hydraulic control valve 100. When the value of D/D is too small, although the leakage phenomenon of the flange-type hydraulic control valve 100 can be prevented, the difference between the thickness of the rubber cover 4 and the diameter of the first chamber 1c is very small, the pressure of the fluid is difficult to jack the rubber cover 4, when the flange-type hydraulic control valve 100 needs to supply the fluid, an auxiliary pressurizing device is needed to separate the rubber cover 4 from the abutting part 3, and the operation is complicated. When D/D is more than or equal to 5 and less than or equal to 10, the flange type hydraulic control valve 100 can be flexibly switched between a conduction state and a stop state, and the sealing effect of the flange type hydraulic control valve 100 can be ensured. Further, D/D = 8.
According to the utility model discloses flange formula water conservancy control valve 100, the internal diameter through controlling first cavity 1c and second cavity 1D is the same, satisfies the relational expression between the diameter D of first cavity 1c and the thickness D of rubber lid 4: D/D is more than or equal to 5 and less than or equal to 10, the flange type hydraulic control valve 100 can be flexibly switched between a conduction state and a stop state, and the sealing effect of the flange type hydraulic control valve 100 can be ensured.
As shown in fig. 1, according to some embodiments of the present invention, the bottom of the rubber cover 4 may be provided with a concave sealing groove 4a facing the direction away from the abutting member 3, and in the closed state, the top of the abutting member 3 may extend into the sealing groove 4a, so that the tightness of the fit between the rubber cover 4 and the abutting member 3 may be improved, and the leakage phenomenon of the flange-type hydraulic control valve 100 may be prevented. Alternatively, two sealing protrusions 41 may be located on the left and right sides of the sealing groove 4a, so that each sealing protrusion 41 may seal the matching structure between the rubber cover 4 and the stopper 3, and the sealing effect of the flange-type hydraulic control valve 100 may be further improved.
As shown in fig. 1, according to some embodiments of the present invention, a side (an upper side as shown in fig. 1) of the rubber cover 4 away from the stopper 3 is provided with a fixing protrusion 42, and one end (a lower end as shown in fig. 1) of the spring 5 can be sleeved on the fixing protrusion 42, so that the connection structure of the spring 5 and the rubber cover 4 can be more firm. Alternatively, the fixing protrusion 42 may be formed in a rectangular parallelepiped shape, and the bottom surface of the fixing protrusion 42 may be parallel to the top surface of the abutting member 3, so that when the flange-type hydraulic control valve 100 is in the off state, the fixing protrusion 42 may completely fit with the abutting member 3, and the leakage prevention performance of the flange-type hydraulic control valve 100 is greatly improved.
As shown in fig. 1, according to some embodiments of the present invention, the inner peripheral wall of the valve cover 2 can be provided with a positioning groove 21 recessed toward the direction away from the rubber cover 4 (upward as shown in fig. 1), and the other end of the spring 5 is embedded in the positioning groove 21, so that the connection between the spring 5 and the valve cover 2 is simpler and firmer, and the operation stability of the flange-type hydraulic control valve 100 is greatly improved.
According to some embodiments of the present invention, the flange-type hydraulic control valve 100 may further include a sealing gasket, and the sealing gasket may be disposed at the top of the abutting member 3 to be in sealing engagement with the rubber cover 4, thereby preventing the leakage phenomenon from occurring in the flange-type hydraulic control valve 100. Alternatively, the gasket may be a piece of silicone material. The silica gel material has soft texture and good sealing performance.
