Abstract
The utility model discloses a hydraulic control valve with a filtering device, and the hydraulic control valve comprises a valve body. One end of the valve body is a water inlet end; the other end of the valve body is a water outlet end; a control cavity is arranged in the valve body; a valve cap is arranged at the top of the control cavity; a valve seat is arranged in the control cavity; a valve rod is connected with the valve seat; the water inlet end of the valve body is provided with a filtering groove and an inserting hole; a filter screen is mounted at the water inlet end of the valve body; one end of the filter screen is clamped in the filtering groove; the other end of the filter screen is inserted into the inserting hole; and the inserting hole is in threaded connection with a filter screen gland. The hydraulic control valve has the characteristics of simple structure, convenience in use, low cost and capability of effectively eliminating impurities in a medium of a pipeline system.
Description
Technical field
The utility model relates to the valve mechanism field, refers more particularly to a kind of hydraulic control valve with filtrating equipment.
Background technique
At present in various pipe-line systems, usually cause pipeline to run well, severe patient even possibly cause the equipment in the pipe-line system to be destroyed because of the impurity that pipeline internal medium exists.Because the hydraulic control valve of conventional construction itself does not have the impurity of removal function; Solution in the past is a design special removal of impurity filter plant in pipe-line system, this mode in application process, exist install complicated, connected element is many, be easy to generate leakages, the inconvenient shortcomings such as (more unfavorable repairing), cost height of keeping in repair.
The model utility content
The purpose of the utility model to above-mentioned deficiency provide a kind of simple in structure, easy to use, cost is low, can effectively remove the hydraulic control valve of the band filtrating equipment of the impurity in the pipe-line system medium.
The utility model is realized through following mode:
A kind of hydraulic control valve with filtrating equipment comprises valve body 1, and an end of valve body 1 is a feed-water end, and the other end is the waterexit end; Be provided with control chamber in the valve body 1, the control chamber top is provided with valve gap 17, is provided with valve seat 4 in the control chamber, and valve rod 5 is connected with valve seat 4; It is characterized in that: valve body 1 feed-water end offers filter vat 11 and patchhole 12; Valve body 1 feed-water end is equiped with filter screen 7, and an end of filter screen 7 is arranged in the filter vat 11, and the other end is inserted in the patchhole 12; Bolt is connected with filter screen gland 9 on the patchhole 12.
Valve body 1 is provided with seal ring 8 with the joint of filter screen gland 9.
The utility model can effectively be removed impurity in the pipe-line system medium, and then guarantee the normal use of miscellaneous equipment in valve and the pipe-line system owing in valve body, be provided with filter screen 7.
In sum, the utility model is the hydraulic control valve of the band filtrating equipment that a kind of simple in structure, installation and maintenance is convenient, cost is low, easy to use.
Description of drawings
Fig. 1 the utility model structural representation.
Embodiment
Combine accompanying drawing at present, the utility model embodiment be detailed:
As shown in Figure 1, a kind of hydraulic control valve with filtrating equipment comprises valve body 1, and an end of valve body 1 is a feed-water end, and the other end is the waterexit end; Be provided with control chamber in the valve body 1, the control chamber top is provided with valve gap 17, is provided with valve seat 4 in the control chamber, and valve rod 5 is connected with valve seat 4; It is characterized in that: valve body 1 feed-water end offers filter vat 11 and patchhole 12; Valve body 1 feed-water end is equiped with filter screen 7, and an end of filter screen 7 is arranged in the filter vat 11, and the other end is inserted in the patchhole 12; Bolt is connected with filter screen gland 9 on the patchhole 12.
Valve body 1 is provided with seal ring 8 with the joint of filter screen gland 9.
The utility model can effectively be removed impurity in the pipe-line system medium, and then guarantee the normal use of miscellaneous equipment in valve and the pipe-line system owing in valve body, be provided with filter screen 7.
The hydraulic control valve part of the utility model is made up of valve body 1, valve seat 4, valve rod 5, diaphragm 6, gland 16, spring 14, valve gap 17; During work; Utilize the upstream and downstream pressure difference in self pipe-line system to be power; Make diaphragm 6 by the differential operation of hydraulic way, regulate automatically by the waterpower of self fully, thereby make valve seat 4 be in adjustment state; Diaphragm 6 on the valve body 1, valve seat 4 all adopt the high-molecular special composite material that rebound elasticity is good, wear resistance is high, friction factor is little to process, and airtight performance is good.
