Ball valve controlling switch is irrigated using PVC more.Irrigation ball valve originally, irrigate that water pressure is very low or no pressure in the case of can open
Open and irrigated, because the operating pressure of irrigation water does not reach design pressure, cause irrigation system uniformity of irrigation water appilcation not reach and set
Evaluation, pour water of poor quality, water wastes serious.
Utility model content
A kind of the defects of the utility model is intended to overcome prior art, there is provided irrigation ball with pressure control switching device
Valve, purpose are exactly that the water pressure in main pipeline could open irrigation ball when reaching at or above branch pipe entrance design work pressure
Valve, irrigation ball valve otherwise can not be opened, to ensure that irrigation system uniformity of irrigation water appilcation reaches design load.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of irrigation ball valve with pressure control switching device, including lid 1, upper valve body 3, seal 4, Handle axis in annular
5th, handle 6, pressure switch apparatus, valve body 13, spherical valve core 14, spherical valve core 14, valve body and upper valve body are installed in valve body 13
Between be fixedly mounted by lid in annular 1 and bolt 2, between valve body 13, spherical valve core 14 and upper valve body 3 coordinate sealing is installed
Body 4, upper valve body 3 are provided with handle 6, and upper valve body 3 is also equipped with pressure switch apparatus.
Further, pressure switch apparatus, including adjusting screw rod 7, regulation body case 8, compression spring 9, upper gliding mass 10, sealing
Ring 11, lower gliding mass 12, adjust in body case 8 and adjusting screw rod 7, compression spring 9 and upper gliding mass 10 are installed, upper gliding mass is connected with down
Gliding mass, adjust and sealing ring 11 is provided between the upper valve body of body case and valve body；When valve is closed, in upper valve body 3 and pressure
The lower gliding mass 12 of the correspondence position of gliding mass 10 installation on switching device, the lower outside of gliding mass 12 set sealing ring 11, upper gliding mass 10 and downslide
Body 12 slides up and down in sealing ring 11.
Further, when valve is closed, upper gliding mass 10 is promoted to enter in sealing ring 11 by the elastic force of compression spring 9, upper gliding mass
10 prevention upper valve bodies 3 rotate, and handle 6 can not drive upper valve body 3 and valve element 14 to horizontally rotate with Handle axis 5, and valve can not be opened.
Compared with prior art, the utility model has following beneficial effect：
The utility model device is simple in construction to be leaned on, easy for installation.1st, have it is common irrigate ball valve without Stress control open
Function is opened, when only irrigation water pressure reaches or surpasses operating pressure, valve could be opened and irrigated, ensures that irrigation system fills
The uniformity of water, improve WUEL.2nd, according to the design work pressure of irrigation system, by adjusting the regulation spiral shell on body
Bolt or the spring for selecting different moduluss of elasticity, set different Opening pressures.
Brief description of the drawings
Fig. 1 is the valve-closed state figure of irrigation ball valve of the utility model with pressure control switching device.
Fig. 2 is the valve opening state figure of irrigation ball valve of the utility model with pressure control switching device.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of irrigation ball valve with pressure control switching device, including lid 1, upper valve body 3, sealing in annular
Body 4, Handle axis 5, handle 6, pressure switch apparatus, valve body 13, spherical valve core 14, spherical valve core 14, valve are installed in valve body 13
It is fixedly mounted by lid in annular 1 and bolt 2 between body and upper valve body, is coordinated between valve body 13, spherical valve core 14 and upper valve body 3
Seal 4 is installed, upper valve body 3 is provided with handle 6, and upper valve body 3 is also equipped with pressure switch apparatus.Above-mentioned pressure switch dress
Put, including adjusting screw rod 7, regulation body case 8, compression spring 9, upper gliding mass 10, sealing ring 11, lower gliding mass 12, adjust body case 8
Adjusting screw rod 7, compression spring 9 and upper gliding mass 10 are inside installed, upper gliding mass is connected with lower gliding mass, adjust body case upper valve body and
Sealing ring 11 is provided between valve body；When valve is closed, pacify in upper valve body 3 with the correspondence position of gliding mass 10 on pressure switch apparatus
Gliding mass 12 is loaded, the lower outside of gliding mass 12 sets sealing ring 11, and upper gliding mass 10 and lower gliding mass 12 slide up and down in sealing ring 11.
The operation principle of this irrigation ball valve：
1) Opening pressure H1 is set：Opening pressure H1 is set according to the operating pressure H of irrigation system, and H1 is equal to compression spring
Elastic force kx, spring force modulus k, amount of spring compression x (lower gliding mass sliding distance L1+ regulating bolts adjustment length L2), irrigation
Hydraulic pressure is P by force, and lower gliding mass bottom surface S, the pressure of irrigation water is PS.
2) this is a kind of normally closed type valve, when valve is closed, promotes upper gliding mass 10 to enter sealing ring by the elastic force of compression spring 9
In 11, upper gliding mass 10 prevents upper valve body 3 from rotating, therefore handle 6 can not drive upper valve body 3 and valve element 14 horizontal with the axle of Handle axis 5
Rotate, valve can not be opened.When pressure water is entered in valve (see Fig. 1) by right side, if PS≤kx, gliding mass 12 and upper under water pressure pushing
The upward sliding of gliding mass 10, when upper gliding mass 10 is pushed out sealing ring 11, handle 6 can drive upper valve body 3 and horizontal turn of valve element 14
It is dynamic 90 °, irrigated so as to open valve.If during PS ﹤ kx, hydraulic pressure can not push gliding mass and slide up, therefore valve can not be opened.
The operating pressure of irrigation water in so ensuring that into branch pipe.
Explanation embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for ability
It is all within the spirit and principles of the utility model for the technical staff in domain, any modification, equivalent substitution and improvements made
Deng should be included within the scope of protection of the utility model.
