Description
Technical Field
The utility model relates to a take Y type filter of ball valve.
Background
A ground source heat pump air conditioning system relates to a large number of devices such as water pumps, heat pump main machines and the like which need Y-shaped filter protection. Each machine room needs nine Y-shaped filters in a small quantity, and needs dozens of Y-shaped filters in a large quantity. The Y-shaped filter is used for removing impurities in the medium so as to protect the water pump and normal use of equipment. However, the Y-filter is often cleaned because of clogging over time. The existing Y-shaped filter with the ball valve comprises a main filter pipe 1 and a side filter pipe 2 which is obliquely connected to the middle of the main filter pipe 1, wherein one end of the main filter pipe 1 is a water inlet 11, the other end of the main filter pipe 1 is a water outlet 12, a filter cavity is arranged in the side filter pipe 2, and a cylindrical filter screen 20 is arranged in the filter cavity. The outlet end of the side filter pipe 2 is provided with a blind plate 3, and the middle part of the blind plate 3 is provided with a through hole for installing a ball valve 4. When the Y-type filter is cleaned, the ball valve 4 is opened, and impurities accumulated on the strainer 20 are discharged through the ball valve 4 by water flow. However, in the actual operation process, due to the inclined arrangement of the side filter tubes 2, impurities can be accumulated at the lower part of the outlet ends of the side filter tubes 2 and the corner A of the blind plate 13 and cannot be discharged, so that the filter is not cleaned completely (see fig. 1).
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a take Y type filter of ball valve, it can accomplish the cleaning of filter screen under the prerequisite of not dismantling Y type filter, and it is more convenient, more thorough to make the washing filter.
The purpose of the utility model is realized like this: a Y-shaped filter with a ball valve comprises the Y-shaped filter and the ball valve; the Y-shaped filter comprises a main filter tube, a main filter tube and a side filter tube obliquely connected to the middle part of the main filter tube, wherein one end of the main filter tube is provided with a water inlet, the other end of the main filter tube is provided with a water outlet, a filter cavity is arranged in the side filter tube, a filter screen is arranged in the filter cavity, wherein,
a blind plate is arranged at the outlet end of the side filter tube, and a notch is formed in the outer end face of the lower part of the blind plate;
the ball valve is arranged in a notch formed in the blind plate;
a back washing port for connecting a back washing pipeline is arranged on the main filter pipe positioned on the upstream side of the filter screen.
In the above Y-shaped filter with a ball valve, a blind flange or a back flush valve is installed on the back flush port.
The utility model discloses a Y type filter of taking ball valve has following characteristics: through with ball valve eccentric settings, make the impurity of piling up in the exit end lower part of side chimney filter and the corner of blind plate thoroughly wash clean. In addition, the water inlet pipe positioned at the upstream side of the filter screen is provided with a back washing port used for connecting a back washing pipeline, so that the back washing of the filter screen can be realized, the disassembly-free cleaning of the filter is realized, the filter is more convenient and more thorough to clean, and the maintenance frequency of the filter is reduced.
Drawings
FIG. 1 is a schematic diagram of a prior art Y-strainer with a ball valve;
fig. 2 is a schematic structural diagram of the Y-shaped filter with the ball valve of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 2, the Y-shaped filter with the ball valve of the present invention includes a Y-shaped filter and a ball valve 10; the Y-shaped filter comprises a main filter tube 1, a main filter tube 1 and a side filter tube 2 obliquely connected to the middle part of the main filter tube 1, wherein,
one end of the main filter pipe 1 is provided with a water inlet 11, and the other end of the main filter pipe 1 is provided with a water outlet 12;
a filter cavity is arranged in the side filter pipe 2, and a cylindrical filter screen 20 is arranged in the filter cavity; the outlet end of the side filter tube 2 is provided with a blind plate 3 ', and the outer end surface of the lower part of the blind plate 3' is provided with a notch;
the ball valve 10 is arranged in a notch formed on the blind plate 3';
a back washing port for connecting a back washing pipeline is arranged on the main filter pipe 1 positioned on the upstream side of the filter screen 20, and a blind flange 4 or a back washing valve is arranged on the back washing port.
The utility model discloses a take Y type filter of ball valve owing to install ball valve 10 eccentrically in the lower part of the exit end of side chimney filter 2, consequently when wasing the filter, opens ball valve 10, just can thoroughly wash away the impurity of piling up in the exit end lower part of side chimney filter 2 and the corner of blind plate 3', can wash the filter under the circumstances of exempting from to dismantle, has reduced the maintenance number of times of filter. In addition, the filter can realize back flushing through an external back flushing pipeline. When backwashing is carried out, the ball valve 10 is closed, the blind flange 4 on the backwashing port is detached and connected with a backwashing sewage discharge pipe, or the backwashing valve is opened, clean water is introduced into the reverse backwashing filter from the water outlet 12 of the main filter pipe 1, and then impurities accumulated on the upstream of the filter screen 20 can be flushed out through the backwashing port and then discharged through the backwashing sewage discharge pipe.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
